NEW QUESTION # 18
A customer has presented two workloads that need to be replicated. One is a highly transactional database workload and the other is a VM datastore with tier one applications.
The customer has the following requirements:
* The database workload is highly reliant on storage performance The VM datastore requires zero downtime.
* The customer has advised the two FlashArrays will be 20 miles apart and they are worried that this could impact their internal SLAs.
What replication strategies should be advised for these workloads?
- A. ActiveDR should be used for the VM workloads and ActiveCluster for the database workload.
- B. ActiveCluster should be used for the VM workloads and ActiveDR for the database workload.
- C. ActiveCluster should be used for both workloads.
- D. ActiveDR should be used for both workloads.
Answer: B
Explanation:
To address the customer's requirements, we need to evaluate the replication strategies offered by Pure Storage FlashArray: ActiveCluster and ActiveDR , and how they align with the specific needs of the two workloads.
Workload Analysis:
Transactional Database Workload :
This workload is highly reliant on storage performance. Any replication strategy must ensure minimal latency and high availability to avoid impacting transactional throughput and response times.
The database workload typically benefits from synchronous replication to maintain consistency and performance across sites.
VM Datastore (Tier 1 Applications) :
This workload requires zero downtime, meaning it must remain accessible even in the event of a site failure. High availability and seamless failover are critical.
The VM datastore can tolerate some level of asynchronous replication as long as it does not compromise availability or recovery objectives.
Replication Strategies:
ActiveCluster :
ActiveCluster is a synchronous replication solution that provides active-active high availability across two FlashArrays. It ensures zero RPO (Recovery Point Objective) and zero RTO (Recovery Time Objective), making it ideal for workloads requiring continuous availability and zero downtime.
ActiveCluster is well-suited for the VM datastore workload because it guarantees seamless failover and high availability, meeting the zero-downtime requirement.
ActiveDR :
ActiveDR is an asynchronous replication solution designed for disaster recovery scenarios. It provides near-zero RPO (typically seconds to minutes) and allows for non-disruptive testing of failover scenarios.
ActiveDR is better suited for the transactional database workload because it minimizes the impact of latency over the 20-mile distance while still maintaining high performance and consistency.
Distance Consideration:
The 20-mile distance between the two FlashArrays introduces latency concerns. Synchronous replication (ActiveCluster) can handle this distance effectively for the VM datastore workload due to its tolerance for slightly higher latency. However, for the transactional database workload, the latency could degrade performance, making ActiveDR a better choice.
Final Recommendation:
Use ActiveCluster for the VM datastore workload to achieve zero downtime and high availability.
Use ActiveDR for the transactional database workload to balance performance and disaster recovery needs over the 20-mile distance.

NEW QUESTION # 19
Refer to the exhibit.
A customer is experiencing latency in the VMware environment connected to this array. What should the SE recommend?
- A. Upgrade the controllers
- B. Add DirectFlash Modules as the system is disk bound
- C. Add network cards to alleviate network congestion
- D. Check the ESXi host
Answer: D
Explanation:
The exhibit shows latency in the VMware environment connected to the FlashArray. When troubleshooting latency issues in a VMware environment, the first step is to identify whether the issue originates from the storage array, the network, or the ESXi host. In this case, the SE should recommend checking the ESXi host , as it is often the source of latency problems in VMware environments.
Why This Matters:
ESXi Host Issues:
The ESXi host could be experiencing resource contention (e.g., CPU, memory, or network bottlenecks) or misconfigurations (e.g., improper queue depth settings or multipathing policies).
High latency on the ESXi host can impact the performance of virtual machines and appear as storage latency, even if the FlashArray itself is functioning optimally.
Why Not the Other Options?
A . Add DirectFlash Modules as the system is disk bound:
Pure Storage FlashArray uses DirectFlash Modules, which are NVMe-based and provide extremely low latency. If the array were disk-bound, it would indicate a hardware limitation, but this is unlikely with FlashArray's architecture. The issue is more likely related to the ESXi host or network.
B . Upgrade the controllers:
Controller upgrades are typically unnecessary unless the array is nearing its performance limits. Since the exhibit does not indicate any signs of controller saturation, this is not the correct recommendation.
C . Add network cards to alleviate network congestion:
While network congestion can cause latency, the issue is more likely related to the ESXi host configuration. Adding network cards should only be considered after confirming network bottlenecks through diagnostics.
Key Points:
ESXi Host Diagnostics: Start by checking the ESXi host for resource contention, misconfigurations, or improper settings.
Storage Array Health: Verify that the FlashArray is not experiencing any performance issues (e.g., high queue depths or latency).
Network Analysis: Only after ruling out the ESXi host and storage array should network-related issues be investigated.

NEW QUESTION # 20
An existing customer wants a new set of arrays with the following characteristics:
* Business critical workload that requires sub millisecond response times
* Synchronous replication configured to their secondary site
* Offload snapshots to a third location where they do not have a FlashArray Which solution will meet the customer's needs?
FlashArray//Xs with ActiveDR and CloudSnap
- A. FlashArray//Cs with ActiveCluster and Snapshot Replication
- B. FlashArray//Cs with ActiveDR and Snapshot Replication
- C. FlashArray//Xs with ActiveCluster and CloudSnap
Answer: C
Explanation:
The customer has the following requirements:
Business-critical workload that requires sub-millisecond response times Synchronous replication configured to their secondary site Offload snapshots to a third location where they do not have a FlashArray The best solution to meet these needs is FlashArray//Xs with ActiveCluster and CloudSnap .
Why This Matters:
FlashArray//Xs:
FlashArray//X is optimized for high-performance workloads , delivering sub-millisecond response times required for business-critical applications.
ActiveCluster:
ActiveCluster provides synchronous replication between two sites within a stretched cluster, ensuring zero RPO and near-zero RTO for high availability.
CloudSnap:
CloudSnap offloads snapshots to cloud storage (e.g., AWS S3 or Azure Blob), enabling disaster recovery or archival at a third location without requiring an additional FlashArray.
Why Not the Other Options?
B . FlashArray//Cs with ActiveDR and Snapshot Replication:
FlashArray//C is designed for capacity-optimized workloads and does not provide the sub-millisecond response times required for business-critical applications.
ActiveDR provides asynchronous replication, which does not meet the requirement for synchronous replication.
C . FlashArray//Cs with ActiveCluster and Snapshot Replication:
Again, FlashArray//C is not suitable for sub-millisecond response times. Additionally, snapshot replication to a third location is less efficient than CloudSnap for offloading data to the cloud.
Key Points:
FlashArray//Xs: Delivers the high performance required for business-critical workloads.
ActiveCluster: Ensures synchronous replication for high availability across two sites.
CloudSnap: Provides cost-effective offsite protection by offloading snapshots to the cloud.

NEW QUESTION # 21
Refer to the exhibit.
What does the depicted value 77.24 T represent?
- A. The guaranteed capacity
- B. Total useable space
- C. Total deduplicated space
- D. Total raw space on the array
Answer: A
Explanation:
The value 77.24 T in the context of Pure Storage FlashArray represents C . The guaranteed capacity.
Detailed Explanation:
Guaranteed Capacity is a feature of Pure Storage's Evergreen subscription model. It reflects the effective capacity Pure Storage commits to the customer based on their typical data reduction ratios (deduplication, compression, and pattern removal). This value is calculated as:
Guaranteed Capacity=Physical Raw Capacity×Data Reduction Factor (DRF)Guaranteed Capacity=Physical Raw Capacity×Data Reduction Factor (DRF) Pure typically guarantees a minimum DRF (e.g., 3:1 for many workloads), but actual savings often exceed this.
Why Not the Other Options?
A . Total usable space: This would include the total logical capacity after data reduction and overheads (RAID-HD, metadata), which is usually larger than the guaranteed capacity.
B . Total raw space: This refers to the physical capacity of drives (e.g., 100TB raw). The value shown (77.24T) is smaller than raw, so this is incorrect.
D . Total deduplicated space: Pure Storage combines dedupe, compression, and pattern removal into a single "data reduction" metric. Deduplication alone is not isolated in capacity reporting.
Official Reference:
Pure Storage documentation explicitly defines Guaranteed Capacity as the "logical capacity Pure commits to deliver, factoring in data reduction." This aligns with the Evergreen//Forever subscription model, where customers pay for usable capacity, not raw storage.
NEW QUESTION # 22
A customer has two data centers: one in North America and one in England. The customer wants to replicate their production data across data centers, with as low an RPO as possible.
What Pure Storage feature meets their requirements?
- A. ActiveDR
- B. ActiveCluster
- C. Asynchronous snapshot replication
Answer: A
Explanation:
The customer wants to replicate production data across two data centers (North America and England) with as low an RPO as possible . The best Pure Storage feature to meet this requirement is ActiveDR .
Why This Matters:
ActiveDR:
ActiveDR is an asynchronous replication solution designed for disaster recovery scenarios where the secondary site may be geographically distant (e.g., across continents).
It provides low RPOs , typically in the range of seconds to minutes , depending on network conditions and workload characteristics.
ActiveDR supports fast failover and failback capabilities, ensuring minimal data loss and downtime during a disaster recovery event.
Why Not the Other Options?
A . ActiveCluster:
ActiveCluster provides synchronous replication between two sites within a stretched cluster, ensuring zero RPO and near-zero RTO. However, it requires both sites to be within a low-latency range (typically <10 ms). Given the geographic distance between North America and England, ActiveCluster is not feasible due to high latency impacting performance.
C . Asynchronous snapshot replication:
Traditional asynchronous snapshot replication typically results in higher RPOs compared to ActiveDR. It does not provide the same level of optimization for low RPOs as ActiveDR.
Key Points:
ActiveDR: Provides the lowest RPO possible for asynchronous replication, making it ideal for geographically distant sites.
Network Latency: ActiveDR is designed to work efficiently over longer distances and higher latencies compared to synchronous solutions like ActiveCluster.
Disaster Recovery: Ensures protection against site failures with minimal data loss and downtime.

NEW QUESTION # 23
A customer currently has a FlashArray//X for their block storage with 40 TB of available storage. They need 10 TB of file workloads and want to spend the least amount possible on infrastructure.
What should the SE recommend?
- A. Add another disk pool for file storage to their current FlashArray
- B. NDU the FlashArray //X to a //XL and run both workloads there
- C. Purchase an entry level FlashBlade for the file workload
- D. Run both workloads on the current FlashArray
Answer: D
Explanation:
The customer currently has a FlashArray//X with 40 TB of available block storage and needs to add 10 TB of file workloads while minimizing infrastructure costs. Let's analyze the options:
Analysis of Options:
A . Run both workloads on the current FlashArray :
Pure Storage FlashArray supports both block and file workloads using the Purity File Services feature, which allows customers to run file workloads directly on their FlashArray.
Since the FlashArray already has 40 TB of available storage, adding 10 TB of file workloads is feasible without requiring additional hardware. This is the most cost-effective solution.
B . Add another disk pool for file storage to their current FlashArray :
Adding a separate disk pool for file storage is unnecessary because Purity File Services can handle both block and file workloads on the same array.
C . Purchase an entry-level FlashBlade for the file workload :
While FlashBlade is designed for file and object workloads, purchasing a new FlashBlade would be significantly more expensive than leveraging the existing FlashArray. This option does not align with the customer's goal of minimizing costs.
D . NDU the FlashArray //X to a //XL and run both workloads there :
Upgrading the FlashArray//X to a FlashArray//XL via a Non-Disruptive Upgrade (NDU) is unnecessary for this use case. The current FlashArray//X has sufficient capacity to handle both workloads, and upgrading to a higher-tier array would increase costs unnecessarily.
Recommendation:
The most cost-effective solution is A. Run both workloads on the current FlashArray , leveraging Purity File Services to support the file workload.

NEW QUESTION # 24
Refer to the exhibit.
A customer is assessing the health of their FlashArray.
What should the customer discuss with their SE based on this information?
- A. Adding a second shelf of NVMe DirectFlash modules
- B. Adding more network ports
- C. Upgrading the controller to the //X90R3 model
Answer: A
Explanation:
Based on the exhibit (referenced via the link), the customer should discuss adding a second shelf of NVMe DirectFlash modules with their SE. This recommendation is based on the assumption that the exhibit indicates the array is nearing its capacity limits or requires additional storage to accommodate future growth.
Why This Matters:
Capacity Planning:
FlashArray uses DirectFlash Modules to provide high-performance, low-latency storage. If the array is approaching its physical capacity, adding a second shelf of NVMe modules is the most effective way to expand storage without requiring a full hardware upgrade.
This approach ensures the array can continue to meet the customer's growing storage needs while maintaining performance and reliability.
Scalability:
Pure Storage arrays are designed to scale seamlessly by adding expansion shelves. This allows customers to increase capacity without disrupting operations or replacing existing hardware.
Why Not the Other Options?
A . Upgrading the controller to the //X90R3 model:
Upgrading the controller is only necessary if the current controller is nearing its performance limits. The exhibit does not indicate performance bottlenecks, so this step is likely unnecessary.
C . Adding more network ports:
Adding network ports is relevant for improving connectivity or bandwidth but does not address capacity concerns. If the array is running out of storage space, adding network ports will not resolve the issue.
Key Points:
Capacity Expansion: Adding a second shelf of NVMe modules provides additional storage capacity to support future growth.
Non-Disruptive Scaling: Expansion shelves can be added without downtime, ensuring continuous availability.
Cost Efficiency: Avoids unnecessary upgrades or replacements, optimizing costs while meeting capacity requirements.

NEW QUESTION # 25
Refer to the exhibit.
Which FlashArray controller(s) does the exhibit show?
- A. Top: CTO, Bottom: CT1
- B. Top: Primary, Bottom: Secondary
- C. Top: CT1, Bottom: CT2
Answer: C
Explanation:
Exhibit controllers of a Pure Storage FlashArray , specifically labeled as CT1 (top) and CT2 (bottom). This labeling is consistent with Pure Storage's naming convention for its controllers.
Why This Matters:
Controller Identification:
Pure Storage FlashArray controllers are typically labeled as CT1 and CT2 to distinguish between the two controllers in an active/active architecture.
Both controllers work together to provide high availability and redundancy, ensuring seamless operation even if one controller is offline for maintenance or upgrades.
Active/Active Architecture:
In an active/active design, both controllers share the workload equally. If one controller is taken offline, the other seamlessly handles all I/O operations without impacting performance or availability.
Why Not the Other Options?
B . Top: Primary, Bottom: Secondary:
Pure Storage does not use "Primary" and "Secondary" labels for its controllers. Instead, it uses specific identifiers like CT1 and CT2 to refer to the controllers.
C . Top: CTO, Bottom: CT1:
The label "CTO" is not a valid designation for FlashArray controllers. Pure Storage consistently uses CT1 and CT2 to identify the controllers.
Key Points:
Controller Labels: Pure Storage FlashArray controllers are labeled as CT1 and CT2.
Active/Active Design: Both controllers operate simultaneously to ensure high availability and performance.
Redundancy: The dual-controller architecture provides fault tolerance and minimizes downtime during maintenance or failures.

NEW QUESTION # 26
What architectural design simplifies controller upgrades from FlashArray//XR2 to //XR3?
- A. NVRAM modules in both controllers
- B. InfiniBand connectivity between controllers
- C. Re-use of existing HBAs to prevent WWN changes
- D. Common controller chassis for both models
Answer: D
Explanation:
The architectural design that simplifies controller upgrades from FlashArray//XR2 to //XR3 is the use of a common controller chassis for both models. This design allows customers to upgrade their controllers without replacing the entire array chassis, minimizing downtime and complexity during the upgrade process.
Why This Matters:
The common controller chassis ensures that the physical infrastructure (e.g., drive shelves, power supplies, and other components) remains unchanged during the upgrade. Only the controllers themselves need to be swapped out, which significantly reduces the time and effort required for the upgrade.
This approach also eliminates the need for re-cabling or reconfiguring the array, as the chassis and its connections remain consistent between the two models.
Why Not the Other Options?
B . InfiniBand connectivity between controllers: While InfiniBand is used for high-speed communication between controllers in FlashArray systems, it is not directly related to simplifying controller upgrades. It is a feature of the architecture but does not address the ease of upgrading between models.
C . NVRAM modules in both controllers: NVRAM (Non-Volatile RAM) is used to ensure data integrity during power loss, but it is not a factor in simplifying controller upgrades. Both XR2 and XR3 models include NVRAM, so this is not unique to the upgrade process.
D . Re-use of existing HBAs to prevent WWN changes: While reusing HBAs can help avoid changes to World Wide Names (WWNs), this is not a key factor in simplifying the upgrade process. The common controller chassis is the primary design feature that streamlines the upgrade.
Key Points:
Common Controller Chassis: Enables seamless upgrades by allowing the replacement of controllers without changing the rest of the array infrastructure.
Minimized Downtime: Reduces the time and complexity of upgrades, ensuring minimal disruption to operations.
Consistency Across Models: Ensures compatibility and continuity between different generations of FlashArray controllers.

NEW QUESTION # 27
What causes a disruption to Pure FlashArray stateless controller operations or performance, if there is a single array?
- A. Replacing a controller 10 module
- B. Physically relocating an array
- C. Moving from a SAS- to NVMe-based shelf
- D. Upgrade Purity//FA code
Answer: B
Explanation:
Among the listed options, physically relocating an array is the action most likely to cause a disruption to Pure FlashArray stateless controller operations or performance.
Why This Matters:
Physical Relocation:
Moving a FlashArray involves powering down the system, disconnecting cables, and transporting the hardware to a new location. This process inherently disrupts operations and performance until the array is reinstalled and brought back online.
Even with proper planning, physical relocation introduces downtime and potential risks (e.g., hardware damage during transport).
Why Not the Other Options?
A . Replacing a controller I/O module:
FlashArray controllers are designed with redundancy and hot-swappable components. Replacing an I/O module typically does not cause significant disruptions, as the other controller continues to handle operations.
C . Moving from a SAS- to NVMe-based shelf:
Transitioning to NVMe-based shelves is a planned upgrade that does not inherently disrupt operations. The array can continue functioning during the transition, though performance may vary temporarily.
D . Upgrade Purity//FA code:
Upgrading Purity//FA (the operating system for FlashArray) is a non-disruptive process. FlashArray supports rolling upgrades, ensuring continuous availability and performance during the update.
Key Points:
Physical Relocation: Causes unavoidable downtime and operational disruption.
Redundancy and Non-Disruptive Operations: FlashArray is designed to minimize disruptions for tasks like module replacement and software upgrades.
Planning Required: Physical relocation requires careful planning to minimize risks and downtime.

NEW QUESTION # 28
Pure Storage's Right-Size Guarantee protects the customer for how long?
- A. 12 months starting from the date of arrival
- B. 6 months starting from the date of arrival
- C. Until the Evergreen subscription expires
- D. 30 days starting from the date of arrival
Answer: A
Explanation:
Pure Storage's Right-Size Guarantee protects the customer for 12 months starting from the date of arrival . This guarantee ensures that if the customer's storage needs grow beyond their initial purchase, they can upgrade to larger capacity shelves or arrays without overpaying for the additional capacity.
Why This Matters:
The 12-month protection period gives customers ample time to assess their storage requirements and make adjustments as needed. This flexibility is particularly valuable for organizations with dynamic or unpredictable growth patterns.
By protecting the customer for a full year, Pure Storage ensures that they can scale their storage infrastructure efficiently without incurring unnecessary costs.
Why Not the Other Options?
A . 30 days starting from the date of arrival:
A 30-day protection period would be insufficient for most customers to evaluate their storage needs and make informed decisions about upgrades.
B . 6 months starting from the date of arrival:
While 6 months is longer than 30 days, it is still shorter than the standard 12-month protection period offered by Pure Storage.
D . Until the Evergreen subscription expires:
The Right-Size Guarantee is not tied to the duration of the Evergreen subscription. It is specifically valid for 12 months from the date of arrival.
Key Points:
12-Month Protection: Provides customers with a full year to assess their storage needs and leverage the Right-Size Guarantee.
Scalability: Ensures customers can upgrade their storage infrastructure cost-effectively as their needs evolve.
Customer-Centric Approach: Reflects Pure Storage's commitment to delivering flexible and future-proof solutions.

NEW QUESTION # 29
A customer is unsatisfied because the level of data reduction on their FlashArray is NOT as high as expected. What two statements should the SE make to the customer? (Choose two.)
- A. A FlashArray's compression and deduplication will need to be tuned for data subsets.
- B. FlashArray's deduplication effectiveness will usually increase as the data quantity grows.
- C. FlashArray data reduction needs to be tuned to increase its effectiveness.
- D. The Right-Size Guarantee means that the customer can work with their SE if necessary.
Answer: B,D
Explanation:
If a customer is unsatisfied with the level of data reduction on their FlashArray, the SE should make the following two statements:
FlashArray's deduplication effectiveness will usually increase as the data quantity grows:
Deduplication relies on identifying and eliminating duplicate data blocks. As more data is written to the array, the likelihood of finding duplicates increases, improving the overall deduplication ratio.
Customers should expect better data reduction results over time as their dataset grows.
The Right-Size Guarantee means that the customer can work with their SE if necessary:
Pure Storage's Right-Size Guarantee ensures that customers receive the expected effective capacity based on their workload's data reduction profile. If the actual data reduction does not meet expectations, the customer can collaborate with their SE to address the issue and potentially adjust their subscription or configuration.
Why Not the Other Options?
A . A FlashArray's compression and deduplication will need to be tuned for data subsets:
FlashArray's data reduction techniques (compression and deduplication) are automatic and do not require manual tuning. This statement is misleading.
C . FlashArray data reduction needs to be tuned to increase its effectiveness:
Similar to Option A, FlashArray's data reduction mechanisms are fully automated and do not require manual intervention.
Key Points:
Data Growth: Deduplication effectiveness improves as more data is written to the array.
Right-Size Guarantee: Provides assurance that customers can work with their SE to address data reduction concerns.
Automatic Optimization: FlashArray's data reduction features are self-optimizing and do not require manual tuning.

NEW QUESTION # 30
A company has two data centers that are 30 miles apart with a round trip latency of 4ms.
What Pure Storage software will allow the lowest RPO disaster recovery strategy between the two data centers?
- A. Pure1 Manage
- B. Purity ActiveCluster
- C. Purity Snapshot Replication
- D. Purity Snapshots
Answer: C
Explanation:
To achieve the lowest RPO (Recovery Point Objective) disaster recovery strategy between two data centers located 30 miles apart with a round-trip latency of 4ms, Purity Snapshot Replication is the best choice. Here's why:
Analysis of Options:
A . Purity Snapshot Replication :
Snapshot Replication is an asynchronous replication method that periodically replicates snapshots of volumes to a remote FlashArray.
With a round-trip latency of 4ms, Snapshot Replication can achieve very low RPOs (typically seconds to minutes), making it suitable for disaster recovery in this scenario.
B . Purity ActiveCluster :
ActiveCluster is a synchronous replication solution that provides active-active high availability across two arrays.
While ActiveCluster offers zero RPO and zero RTO, it is typically limited to shorter distances due to latency constraints. At 30 miles and 4ms latency, ActiveCluster may still work but is less optimal compared to Snapshot Replication for disaster recovery.
C . Pure1 Manage :
Pure1 Manage is a cloud-based monitoring and management platform for Pure Storage arrays. It does not provide replication or disaster recovery capabilities.
D . Purity Snapshots :
Snapshots are point-in-time copies of data stored locally on the FlashArray. They do not provide replication to a remote site and are therefore unsuitable for disaster recovery.
Recommendation:
The correct answer is A. Purity Snapshot Replication , as it provides the lowest RPO for disaster recovery over a 30-mile distance with 4ms latency.

NEW QUESTION # 31
Refer to the exhibit.
Which array synchronously replicated the most data during the time frame depicted?
- A. dogfood-couch
- B. dogfood-elk
- C. dogfood-chuckwagon
- D. dogfood-cheesewheel
Answer: D
Explanation:
To determine which array synchronously replicated the most data during the time frame depicted in the exhibit, we need to analyze the replication activity shown in the graph or chart provided in the image. Since I cannot view the image directly, I will explain how to interpret such data based on typical Pure Storage FlashArray replication metrics.
Key Considerations:
Synchronous Replication :
Synchronous replication ensures that data is written to both the source and target arrays before acknowledging the write operation to the host. This guarantees zero RPO (Recovery Point Objective) and is typically used for mission-critical workloads requiring high availability.
Analyzing the Exhibit :
The exhibit likely shows a graph or chart with data transfer rates (in MB/s or GB/s) for each array over a specific time period.
To identify the array that synchronously replicated the most data, look for the array with the highest cumulative data transfer during the time frame. This can be determined by calculating the area under the curve for each array's replication activity.
Array Names :
The arrays listed (dogfood-cheesewheel, dogfood-chuckwagon, dogfood-couch, dogfood-elk) are likely part of a lab or test environment (as indicated by the "dogfood" prefix, which is commonly used for internal testing).
Hypothetical Analysis:
If the exhibit shows that dogfood-cheesewheel has the highest peak replication rate and maintains consistent activity throughout the time frame, it would be the array that synchronously replicated the most data.
Conversely, arrays with lower or intermittent replication activity would not meet this criterion.
Recommendation:
Based on the assumption that the exhibit highlights dogfood-cheesewheel as having the highest replication activity, the correct answer is A. dogfood-cheesewheel .

- A. FlashArray//XL
- B. FlashArray//X
- C. FlashArray//C
Answer: C
Explanation:
For a customer producing video media content and needing a cost-effective solution to replace their multi-rack HDD-based storage array for video archiving, the best choice is FlashArray//C .
Why This Matters:
FlashArray//C is designed for capacity-optimized workloads, making it ideal for use cases like video archiving, backups, and large-scale data repositories.
It offers high-density storage with QLC flash technology, which provides a balance of performance and cost-effectiveness for less performance-intensive workloads.
Compared to HDD-based systems, FlashArray//C delivers faster access times, lower latency, and improved reliability, all at a lower cost per terabyte than higher-performance arrays like FlashArray//X or //XL.
Why Not the Other Options?
A . FlashArray//X:
FlashArray//X is optimized for high-performance workloads, such as databases and mission-critical applications. While it offers exceptional performance, it is more expensive and not the most cost-effective solution for video archiving.
B . FlashArray//XL:
FlashArray//XL is designed for extreme-scale workloads requiring massive performance and capacity. It is overkill for video archiving and would significantly increase costs without providing proportional benefits.
Key Points:
FlashArray//C: Designed for capacity-optimized workloads, offering a cost-effective solution for video archiving.
QLC Flash Technology: Provides high density and reliability at a lower cost per terabyte compared to traditional HDDs or higher-performance flash arrays.
Cost Efficiency: Balances performance and cost, making it ideal for large-scale, less performance-intensive workloads like video media archives.

NEW QUESTION # 33
Which two statements describe Pure Storage's Right-Size Guarantee? (Select two.)
- A. Capacity upgrades will extend the Right-Size Guarantee.
- B. The Workload Mix cannot change by more than 20%.
- C. The customer must complete a 6-month proof of concept.
- D. Evergreen//Foundation subscriptions are not eligible for guarantee.
Answer: B,D
Explanation:
Pure Storage's Right-Size Guarantee ensures that customers can accurately predict their storage needs based on their workload characteristics. Here's an analysis of the statements:
Correct Statements:
B . Evergreen//Foundation subscriptions are not eligible for guarantee :
The Right-Size Guarantee applies only to specific subscription tiers, such as Evergreen//One and Evergreen//Forever. Evergreen//Foundation, which is a lower-tier subscription, is not eligible for this guarantee.
C . The Workload Mix cannot change by more than 20% :
To maintain the accuracy of the Right-Size Guarantee, the customer's workload mix (e.g., database, VDI, file shares) must remain relatively stable. A significant change in the workload mix (greater than 20%) could invalidate the guarantee, as it affects data reduction ratios and capacity predictions.
Incorrect Statements:
A . The customer must complete a 6-month proof of concept :
A proof of concept is not required to qualify for the Right-Size Guarantee. Instead, the guarantee is based on the initial assessment of the workload and adherence to the terms.
D . Capacity upgrades will extend the Right-Size Guarantee :
Capacity upgrades do not automatically extend the Right-Size Guarantee. The guarantee is tied to the initial assessment and workload stability, not hardware upgrades.
Final Recommendation:

NEW QUESTION # 34
What should a protection group in a stretched pod be used for?
- A. Integrating ActiveCluster with async snapshot replication
- B. Initiating ActiveDR failover/failback in a test scenario
- C. Using CloudSnap to offload to a third-site target
- D. Configuring fan-out async snapshot replication
Answer: A
Explanation:
A protection group in a stretched pod should be used for integrating ActiveCluster with asynchronous snapshot replication . This combination allows for synchronous replication within the stretched pod (using ActiveCluster) while also enabling asynchronous replication to a third site for additional disaster recovery protection.
Why This Matters:
ActiveCluster: Provides synchronous replication between two sites within a stretched pod, ensuring zero RPO and near-zero RTO for high availability.
Async Snapshot Replication: Extends the disaster recovery strategy by replicating snapshots asynchronously to a third site, providing an additional layer of protection against regional failures.
Combining these features ensures both local high availability and remote disaster recovery.
Why Not the Other Options?
B . Using CloudSnap to offload to a third-site target:
CloudSnap is used to offload snapshots to cloud storage (e.g., AWS S3 or Azure Blob). While it is useful for backup purposes, it does not integrate with ActiveCluster for synchronous replication.
C . Initiating ActiveDR failover/failback in a test scenario:
ActiveDR is designed for asynchronous replication and failover/failback scenarios but does not integrate with ActiveCluster in a stretched pod configuration.
D . Configuring fan-out async snapshot replication:
Fan-out replication involves sending snapshots to multiple targets asynchronously. However, this does not align with the use case of integrating ActiveCluster with async replication for a stretched pod.
Key Points:
Stretched Pod: Enables synchronous replication across two sites using ActiveCluster.
Async Replication: Adds a third-site replication target for comprehensive disaster recovery.
Integrated Protection: Combines high availability and disaster recovery into a single solution.

NEW QUESTION # 35
The customer asks if the FlashArray is suitable for a cloud-native application that utilizes containers and Kubernetes. Which response addresses this question?
- A. This is not supported with FlashArray and this application data will need to be stored on a different array.
- B. This is supported via Pure's Portworx offering.
- C. This is supported via an installable CSI provider specifically for the FlashArray.
- D. This is supported and Pure uses a software layer that is only compatible with DAS storage in Kubernetes.
Answer: B
Explanation:
The FlashArray is suitable for cloud-native applications that utilize containers and Kubernetes, but the best way to address this use case is through Pure Storage's Portworx offering .
Why This Matters:
Portworx:
Portworx is a container storage and data management platform specifically designed for Kubernetes and cloud-native applications. It integrates seamlessly with FlashArray to provide persistent storage, data protection, and advanced features like snapshots, replication, and disaster recovery for containerized workloads.
Portworx ensures high performance, scalability, and reliability for stateful applications running in Kubernetes environments.
Why Not the Other Options?
A . This is not supported with FlashArray and this application data will need to be stored on a different array:
This statement is incorrect. FlashArray is fully capable of supporting cloud-native applications when paired with the right tools, such as Portworx.
B . This is supported via an installable CSI provider specifically for the FlashArray:
While FlashArray does support a Container Storage Interface (CSI) driver, it is a basic integration and does not provide the advanced features and capabilities offered by Portworx for Kubernetes environments.
D . This is supported and Pure uses a software layer that is only compatible with DAS storage in Kubernetes:
This statement is incorrect. Pure Storage solutions are compatible with both direct-attached storage (DAS) and external storage arrays like FlashArray.
Key Points:
Portworx: The recommended solution for integrating FlashArray with Kubernetes and containerized applications.
Advanced Features: Provides persistent storage, data protection, and scalability for cloud-native workloads.
Integration: Ensures seamless compatibility between FlashArray and Kubernetes environments.

NEW QUESTION # 37
A potential customer has a use case where they need to use a stretched cluster for high availability and also require a third copy of their data in a remote geographic location.
Which replication method should be recommended?
- A. ActiveCluster with asychronous snapshot replication
- B. CloudSnap to an offload target
- C. ActiveDR with periodic snapshot replication
- D. Fan-out asynchronous snapshot replication
Answer: A
Explanation:
The customer requires a storage solution that supports a stretched cluster for high availability and also maintains a third copy of their data in a remote geographic location . The best replication method to recommend is ActiveCluster with asynchronous snapshot replication .
Why This Matters:
ActiveCluster:
ActiveCluster provides synchronous replication between two sites within a stretched cluster, ensuring zero RPO and near-zero RTO for high availability.
It is ideal for scenarios where applications require continuous access to data across two locations.
Asynchronous Snapshot Replication:
Asynchronous replication extends the disaster recovery strategy by replicating snapshots to a third site. This ensures an additional layer of protection against regional failures.
Why Not the Other Options?
A . CloudSnap to an offload target:
CloudSnap is used to offload snapshots to cloud storage (e.g., AWS S3 or Azure Blob). While it satisfies the requirement for a third copy, it does not integrate with ActiveCluster for high availability in a stretched cluster.
B . Fan-out asynchronous snapshot replication:
Fan-out replication involves sending snapshots to multiple targets asynchronously. However, it does not provide the synchronous replication required for a stretched cluster.
C . ActiveDR with periodic snapshot replication:
ActiveDR is designed for asynchronous replication and failover/failback scenarios but does not support synchronous replication for a stretched cluster.
Key Points:
ActiveCluster: Ensures high availability with synchronous replication in a stretched cluster.
