,Q1. A FlashArray//X array reports a data reduction ratio of 6.5:1. If the array has
100 TB of effective capacity (after RAID overhead) and currently stores 45 TB of
written data, what is the approximate physical space consumed by user data, and how
much effective capacity remains for new writes, assuming no additional data
reduction?
A. Physical used 6.9 TB; available effective 55 TB
B. Physical used 6.9 TB; available effective 55 TB
C. Physical used 292.5 TB; available effective 55 TB
D. Physical used 6.9 TB; available effective 70.8 TB
Correct Answer: A. Physical used 6.9 TB; available effective 55 TB
Rationale: The physical used is calculated as logical written data divided by data
reduction ratio: 45 TB / 6.5 6.9 TB. The available effective capacity is the total effective
capacity minus logical written data: 100 TB - 45 TB = 55 TB. Options B and D are
duplicates or miscalculate available capacity; option C incorrectly multiplies instead of
dividing.
Why Wrong:
B - Duplicate of A; no distinct rationale.
C - Incorrectly multiplies logical data by the ratio, yielding nonsensical physical
usage.
D - Subtracts physical used from effective capacity instead of logical used, giving an
incorrect remaining value.

Q2. An administrator needs to ensure that a FlashArray//M10R2 can synchronously
replicate a critical workload to a remote site with a round-trip latency of 2 ms. The
workload writes 50,000 IOPS with an average I/O size of 8 KB. Which consideration
is most critical for meeting the RPO of zero?
A. Ensure the array's NVRAM is sized to hold 100 MB of write data
B. Verify that the replication link bandwidth is at least 400 MB/s
C. Confirm that the remote array has identical hardware specifications
D. Enable asynchronous replication to avoid latency impact
Correct Answer: B. Verify that the replication link bandwidth is at least 400 MB/s
Rationale: Synchronous replication requires the replication link to handle the sustained
write throughput without becoming a bottleneck. The required bandwidth is 50,000 IOPS ×
8 KB = 400 MB/s. Without sufficient bandwidth, writes will be delayed, breaking the RPO.
NVRAM sizing (A) is less critical, identical hardware (C) is not required, and
asynchronous replication (D) would not provide RPO zero.
Why Wrong:
A - NVRAM buffers writes but does not guarantee replication bandwidth; the link
Page 3
, capacity is the limiting factor.
C - Synchronous replication does not require identical hardware; it only requires
compatibility and sufficient resources.
D - Asynchronous replication introduces a data loss window, violating the RPO of
zero.

Q3. A storage administrator is planning a migration from a legacy array to a
FlashArray//X. The workload is highly random with a 70/30 read/write ratio. Which
FlashArray feature is specifically designed to accelerate read performance by
leveraging persistent memory?
A. Unified Flash Management (UFM)
B. DirectFlash Modules (DFM)
C. NVMe over Fabrics (NVMe-oF)
D. ActiveReduce with inline deduplication
Correct Answer: B. DirectFlash Modules (DFM)
Rationale: DirectFlash Modules (DFM) are custom NVMe flash modules that bypass the
traditional SSD controller, allowing the array's software to manage flash directly. This
reduces latency and improves random read performance. UFM is a management tool,
NVMe-oF is a protocol, and ActiveReduce is for data reduction, not specifically read
acceleration.
Why Wrong:
A - UFM is a management interface, not a performance acceleration feature.
C - NVMe-oF provides network access but does not inherently accelerate read
performance on the array.
D - ActiveReduce focuses on capacity efficiency, not read latency reduction.

Q4. An administrator needs to provide a development team with writable snapshots
of a production volume for testing. The team requires that changes made to the
snapshot do not affect the production volume and that the snapshot can be promoted
to a full volume. Which Pure Storage feature should be used?
A. Volume clone
B. Snapshot schedule
C. Pod with ActiveDR
D. Protection group
Correct Answer: A. Volume clone
Rationale: A volume clone is a writable copy of a volume that is independent of the
source. It allows modifications without affecting the original and can be promoted to a full
