Question 5
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. Run both workloads on the current FlashArray
- B. Add another disk pool for file storage to their current FlashArray
- C. Purchase an entry level FlashBlade for the file workload
- D. NDU the FlashArray //X to a //XL and run both workloads there
Answer:
A
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.

Question 7
A customer has a requirement for 450 TB of block storage to support their tier2 environment where
latency is not a concern. The workload is expected to achieve a 4-to-l data reduction.
Which array and capacity configuration is the minimum required to meet their needs?
- A. FlashArray//C40R3 247 TB
- B. FlashArray//C60R3 878 TB
- C. FlashArray//X70R3 228 TB
- D. FlashArray//C60R3 366 TB
Answer:
A
Explanation:
To meet the customer's requirement for 450 TB of block storage with a 4:1 data reduction ratio, we
need to calculate the effective usable capacity required and select the appropriate array
configuration.
Step-by-Step Calculation:
Effective Usable Capacity Needed :
The workload requires 450 TB of logical storage.
With a 4:1 data reduction ratio, the physical storage required is:
Array Selection :
The selected array must provide at least 112.5 TB of usable capacity after accounting for overhead
and RAID protection.
Let's evaluate the options:
A . FlashArray//C40R3 247 TB :
The FlashArray//C40R3 provides 247 TB of raw capacity. After accounting for overhead (typically
~20%), the usable capacity is approximately:Usable Capacity=247TB×0.8=197.6TB.
This exceeds the required 112.5 TB , making it a valid option.
B . FlashArray//C60R3 878 TB :
The FlashArray//C60R3 provides 878 TB of raw capacity, which is significantly larger than needed.
While it meets the requirement, it is not the minimum configuration.
C . FlashArray//X70R3 228 TB :
The FlashArray//X70R3 provides 228 TB of raw capacity. After overhead, the usable capacity is
approximately:Usable Capacity=228TB×0.8=182.4TB.
While this also meets the requirement, it is more expensive than the C40R3.
D . FlashArray//C60R3 366 TB :
The FlashArray//C60R3 with 366 TB of raw capacity is overkill for this requirement and not cost-
effective.
Recommendation :
The FlashArray//C40R3 247 TB provides the minimum required usable capacity while meeting the

Question 9
Refer to the exhibit.
Which array synchronously replicated the most data during the time frame depicted?
- A. dogfood-cheesewheel
- B. dogfood-chuckwagon
- C. dogfood-couch
- D. dogfood-elk
Answer:
A
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 .

Question 10
A customer wants to store 100 TiB of Oracle data and 200 TiB of VDI data onto a FlashArray. When
checking the data reduction ratio, the given data reduction ratios are 4:1 for Oracle and 5:1 for VDI.
What is the minimum useable capacity needed on the FlashArray?
- A. 40TiB
- B. 65TiB
- C. 300TiB
- D. 750TiB
Answer:
A
Explanation:
To calculate the minimum usable capacity needed on the FlashArray, we must account for the data
reduction ratios provided for Oracle and VDI workloads. Here's the step-by-step calculation:
Given Data:
Oracle data: 100 TiB with a 4:1 data reduction ratio.
VDI data: 200 TiB with a 5:1 data reduction ratio.
Calculation:
Oracle Data Reduction :
Effective capacity after reduction = 100 TiB ÷ 4 = 25 TiB .
VDI Data Reduction :
Effective capacity after reduction = 200 TiB ÷ 5 = 40 TiB .
Total Usable Capacity Needed :
Total effective capacity = 25 TiB (Oracle) + 40 TiB (VDI) = 65 TiB .
Recommendation:
The minimum usable capacity needed on the FlashArray is 65 TiB . However, since the question asks
for the minimum usable capacity and the options include 40 TiB , it appears there may be a
misunderstanding in the question phrasing. Assuming the intent is to find the total usable capacity,
the correct answer is 65 TiB .

Question 11
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. Purity Snapshot Replication
- B. Purity ActiveCluster
- C. Pure1 Manage
- D. Purity Snapshots
Answer:
A
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.

- D. Capacity upgrades will extend the Right-Size Guarantee.
Answer:
BC
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:
The correct answers are B. Evergreen//Foundation subscriptions are not eligible for guarantee and C.
The Workload Mix cannot change by more than 20% .

- D. Install Pure Storage SRA for VMware Site Recovery Manager (SRM)
Answer:
C
Explanation:
To gain more insight and control over their Pure Storage FlashArray and VMware environment from a
single user interface, the customer should configure the FlashArray Management Pack for vRealize
Operations Manager (vROps) . Here's why:
Analysis of Options:
A . Ensure all VMware API for Array Integration (VAAI) primitives are enabled :
VAAI is a set of APIs that offloads storage tasks from the ESXi host to the storage array, improving
performance and efficiency. However, it does not provide a unified interface for managing both
FlashArray and VMware environments.
B . Log in to the FlashArray GUI and install the plugin for vSphere Client :
While the FlashArray plugin for vSphere Client provides some integration, such as provisioning and
monitoring FlashArray volumes directly from the vSphere Client, it does not offer comprehensive
visibility and control over both environments from a single interface.
C . Configure FlashArray Management Pack for vRealize Operations Manager :
The FlashArray Management Pack for vROps integrates Pure Storage FlashArray with VMware
vRealize Operations Manager, enabling centralized monitoring, analytics, and management of both
environments from a single pane of glass.
This solution provides deep insights into storage performance, capacity utilization, and health
metrics, making it the ideal choice for the customer's requirement.
D . Install Pure Storage SRA for VMware Site Recovery Manager (SRM) :
The Pure Storage Storage Replication Adapter (SRA) is used for disaster recovery orchestration with

Question 14
An admin is setting up replication and has set up a Protection Group. What are the three choices
when adding Members? (Select three.)
- A. Add Hosts
- B. Add Volumes
- C. Add Snapshots
- D. Add Host Groups
- E. AddHBAWWN
Answer:
B, C, D
Explanation:
When setting up replication on a Pure Storage FlashArray, an admin creates a Protection Group to
define which entities will be replicated to a remote FlashArray. When adding members to a
Protection Group, there are three valid choices: Volumes , Snapshots , and Host Groups . Here's a
breakdown of each option:
Choices for Adding Members:
Add Volumes :
Volumes are the primary entities that can be added to a Protection Group. Replication ensures that
the data within these volumes is copied to the remote FlashArray.
This is the most common use case for replication, especially for protecting critical data such as
databases or virtual machine disks.
Add Snapshots :
Snapshots of volumes can also be added to a Protection Group. This allows point-in-time copies of
the data to be replicated to the remote array.
Snapshots are useful for disaster recovery scenarios where you need to restore data to a specific
point in time.
Add Host Groups :
Host Groups can be added to a Protection Group to replicate all volumes associated with the host
group. This simplifies management when multiple volumes are tied to a single application or server.
Replicating Host Groups ensures that all related volumes are protected together, maintaining
consistency across the workload.
Incorrect Options:
A . Add Hosts :
Hosts themselves cannot be directly added to a Protection Group. Instead, replication focuses on the
data (volumes) or logical groupings (host groups) associated with the hosts.
E . Add HBA WWN :
HBA WWNs (World Wide Names) are identifiers for Fibre Channel adapters and are not relevant to
replication or Protection Groups. They are used for zoning and connectivity but do not play a role in
defining replication members.
Final Recommendation:
The correct options are B. Add Volumes , C. Add Snapshots , and D. Add Host Groups , as these are
the valid entities that can be added to a Protection Group for replication.

Question 15
A potential healthcare customer wants to move to a modern storage array for their medical records
database. They need the fastest possible array as their workload is highly transactional.
Which solution should an SE recommend?
- A. FlashArray//XL
- B. FlashArray//X
- C. FlashArray//C
Answer:
A
Explanation:
To meet the healthcare customer's requirement for the fastest possible array for a highly
transactional medical records database, FlashArray//XL is the optimal choice. Here's why:
Analysis of FlashArray Models:
FlashArray//XL :
The FlashArray//XL is Pure Storage's highest-performance all-flash storage array, designed for
mission-critical, high-transaction workloads that demand ultra-low latency and maximum
throughput.
It offers the highest IOPS (Input/Output Operations Per Second), bandwidth, and capacity scaling
capabilities in the FlashArray family, making it ideal for workloads like medical records databases
that require extreme performance.
With its advanced NVMe architecture and DirectFlash Modules, FlashArray//XL delivers sub-
millisecond latency and exceptional performance consistency, which are critical for transactional
workloads.
FlashArray//X :
The FlashArray//X is a high-performance all-flash array but is positioned below the FlashArray//XL in
terms of raw performance and scalability.
While it is suitable for most enterprise workloads, it may not provide the same level of performance
as FlashArray//XL for highly transactional databases with demanding I/O requirements.
FlashArray//C :
The FlashArray//C is optimized for capacity and cost efficiency rather than raw performance.
It uses QLC NAND flash technology, which is more cost-effective but has lower endurance and
performance compared to the TLC NAND used in FlashArray//X and FlashArray//XL.
This makes FlashArray//C unsuitable for highly transactional workloads like a medical records
database.
Recommendation:
Given the customer's need for the "fastest possible array" and the highly transactional nature of their
workload, FlashArray//XL is the best recommendation. Its ability to deliver consistent, low-latency
performance at scale ensures that the medical records database will perform optimally under heavy
transactional loads.
