, 1.A batch application reading data from FlashBlade is changed to issue fewer, larger reads. During its
next run, the engineer observes lower read IOPS but higher read throughput. The application owner asks
whether storage performance has deteriorated.
Which two additional measurements are most useful for assessing these observations? (Choose two.)
A. The array's data-reduction ratio during each run
B. The average size of completed read requests during each run
C. The physical storage utilization at the end of each run
D. The read I/O response times during each run
E. The number of files retained after each run
Answer: B, D
Explanation:
● B: Request size helps explain why fewer operations can transfer more data per second. A lower IOPS
value by itself does not establish a regression when the workload changes.
● D: Response times show whether individual reads are taking longer, adding a responsiveness
measure to the observed transfer rate. Interpret this alongside the application's requirements; the
measurements alone do not establish a root cause.
● A: Data reduction describes storage efficiency, not the size and completion time of the observed reads.
● C: Physical utilization may matter in a broader investigation, but it does not directly resolve the IOPS-
versus-throughput comparison.
● E: File count does not measure the data transferred by each read or its response time.

2.A team is evaluating FlashBlade//S for two applications. One requires NFS access to its working files.
The other writes a separate data set through an S3 API. The team wants to keep both application
interfaces and consolidate storage without introducing a protocol gateway.
Which proposed design best fits this requirement?
A. Place both data sets in NFS file systems and translate the S3 application's requests through a
gateway.
B. Place both data sets in S3 buckets and modify the file application to use object requests.
C. Use native NFS file services for one application and native S3 buckets for the other on FlashBlade//S.
D. Deploy separate FlashBlade//S systems because file and object services require different storage
platforms.
Answer: C
Explanation:
● C: FlashBlade//S supports native file and object access, allowing these separate workloads to share a
platform.
● A: This introduces the gateway the customer wants to avoid.
● B: This requires the application-interface change the customer has ruled out.
● D: Separate arrays are not required merely because one workload uses NFS and the other S3.
This is a protocol-suitability decision, not a completed sizing recommendation. It does not imply that an
NFS file is also exposed as an S3 object.
