Correct Answer: A

Question 2

On a RDMA cluster, a latency test was conducted, with these results:

What should you do?

A. Rerun the test and see If It Is consistent.

B. Report the higher latency through a SR.

C. Nothing, this behavior is normal.

D. Latency Is not critical, check the bandwidth.

Correct Answer: C

Question 3

What HDFS replication factor can be used with Block Volumes to optimize cost?

A. 4

B. 3

C. 1

D. 2

Correct Answer: D

Question 4

A two node clustered/parallel filesystem built using Baremetal Compute shape (BM.Standard2.52) and Block Volume Storage delivers maximum sustained aggregate IO throughput of 5GB/s for read and write, while storing a single copy of the data (replica=l) in filesystem.
What will be the maximum sustained aggregate IO throughput for read and write, when two copies of the data (replica=2) are stored in filesystem for High Availability?

A. 2.5GB/s for readand 5GB/s for write

B. 2.5GB/s for both (read and write)

C. 2.5GB/S for write and 5GB/s for read

D. 5GB/s for both (read and write)

Correct Answer: B

Question 5

You have two different workloads, workload 1 does not scale very well (~100 cores) and requires a very high memory bandwidth, and a workload 2 that Is compute bound and IO intensive.
Which Instances shouldyou select?

A. 1: BM.HPC2.36 2: BM.Standard.2.52

B. 1: BM.Standard.E3.128 2: BM.HPC2.36

C. 1: BM.Standard-2.52 2: BM.HPC2-36

D. 1: BM.HPC2.36 2: BM.Standard.E3-128

Correct Answer: D

Question 6

What does the Terasort phase of the Terasort benchmark do?

A. It randomly maps source data and increases output to a bigger data set.

B. Itmaps and reduces source data in a parallel manner, leveraging data locality to minimize network transfer.

C. It maps and reduces one terabyte of data into a smaller data set.

D. It randomly maps source data and reduces output to a smaller data set,
