,Q1. In a Pure Storage FlashArray//X deployment, a storage administrator observes
that the effective capacity is significantly higher than the raw capacity despite a low
deduplication ratio. Which data reduction mechanism is most likely responsible for
this discrepancy?
A. Inline deduplication using SHA-256 hash comparisons
B. Pattern removal and zero-write elimination
C. Compression using LZ4 algorithm
D. Over-provisioning and thin provisioning
Correct Answer: B. Pattern removal and zero-write elimination
Rationale: Pattern removal identifies repetitive data blocks (e.g., all zeros) and stores only
metadata, drastically reducing capacity usage even when deduplication is low.
Deduplication (A) and compression (C) are also used but are less effective on
non-repetitive data. Thin provisioning (D) affects logical vs. physical allocation but does
not reduce stored data.
Why Wrong:
A - Deduplication is effective but would show a high dedup ratio; the scenario
specifies low dedup.
C - Compression reduces size but is typically not the primary cause when dedup is
low and capacity savings are high.
D - Thin provisioning affects allocation, not the actual data footprint reduction.

Q2. A company is deploying a new Pure Storage FlashArray//XL for a
mission-critical Oracle database. They require synchronous replication to a
secondary site 50 km away. Which Pure Storage feature should be configured to meet
this requirement?
A. ActiveCluster with synchronous replication
B. Async replication with a 15-minute RPO
C. Snapshot-based backup to Pure1
D. Cloud Block Store for DR
Correct Answer: A. ActiveCluster with synchronous replication
Rationale: ActiveCluster provides synchronous replication between two FlashArrays,
ensuring zero RPO and automatic failover, which is essential for mission-critical
databases over a metro distance. Async replication (B) has a higher RPO. Snapshots (C)
are not replication. Cloud Block Store (D) is a different platform, not a direct replication
feature.
Why Wrong:
B - Async replication does not provide zero RPO and is not synchronous.
C - Snapshots are for point-in-time recovery, not continuous replication.
Page 3
, D - Cloud Block Store is an alternative storage service, not a replication feature.
Reference: Pure Storage DSA Study Guide, Ch. 7: Replication and DR
Q3. A storage architect is designing a solution for a large-scale genomic research
environment that requires massive parallel throughput for file and object data.
Which Pure Storage platform and configuration is most appropriate?
A. FlashArray//M with NFS shares
B. FlashBlade//S with a single file system
C. FlashArray//C with SMB shares
D. FlashBlade//E with multiple file systems
Correct Answer: B. FlashBlade//S with a single file system
Rationale: FlashBlade is designed for high-throughput, parallel workloads like genomics,
offering unified file and object storage. FlashBlade//S provides high performance, while
//E is optimized for capacity. A single file system can scale to exabytes and deliver the
required parallelism. FlashArray is block-optimized and not suited for massive parallel
file access.
Why Wrong:
A - FlashArray is a block storage platform, not optimized for parallel file workloads.
C - FlashArray//C is capacity-optimized block storage, not for high-throughput file.
D - FlashBlade//E is capacity-focused, not performance-focused; also multiple file
systems are not the key advantage.
Reference: Pure Storage DSA Study Guide, Ch. 3: FlashBlade Architecture
Q4. In a Pure Storage FlashArray, a volume is configured with a 5 TiB size, but only
2 TiB of data has been written. A snapshot is taken. Subsequently, 1 TiB of new data
is written to the volume. What is the total physical capacity consumed by the volume
and its snapshot, assuming no data reduction?
A. 2 TiB
B. 3 TiB
C. 5 TiB
D. 6 TiB
Correct Answer: B. 3 TiB
Rationale: The snapshot initially consumes no extra physical space as it shares the
original 2 TiB of data. After writing 1 TiB of new data, the original 2 TiB is preserved by
the snapshot, and the new 1 TiB is additional, totaling 3 TiB. The volume size (5 TiB) is
logical, not physical.
Why Wrong:
A - This ignores the new data written after the snapshot.
C - This confuses logical volume size with physical capacity used.
