Question 1

On Oracle Cloud Infrastructure (OCI), a customer wants to build a3TB filesystem for high IOPS workloads (like relational databases, small files, etc).
Which action provides the highest IOPS using OCI block volumes for storage?

A. Attach one Block volume of 3TB volume size and use filesystem Block size of 4K.

B. Attach three Block volumes of 1TB each and use filesystem Block size of 4K.

C. Attach three Block volumes of 1TB each and use filesystem Block size of 2M or higher.

D. Attach one Block volume of 3TB volume size and use filesystem Block size of 2M or higher.

Correct Answer: A

Question 2

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

What should you do?

A. Latency Is not critical, check the bandwidth.

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

C. Nothing, this behavior is normal.

D. Report the higher latency through a SR.

Correct Answer: C

Question 3

You are architecting the infrastructure for a file system.
What are the different criteria you should use, and in what order to build a filesystem for optimal performance?

A. Network Bandwidth > Number of Compute Cores/RAM >Storage

B. Storage > Network Bandwidth > Number of Compute Cores/RAM

C. Number of Compute Cores/RAM > Storage > Network Bandwidth

D. Network Bandwidth > Storage > Number of Compute Cores/RAM

Correct Answer: A

Question 4

A customer has a very busy workload. The model is very large (1 PB range) and only some small files are updated for new jobs. Throughput needed during the run is roughly 25GB/s.
What Is a fast and cost-conscious way to handle the file system?

A. Build a file system using Block volumes and Standard BMs, take advantage of the different block volume performances levels.

B. Put the data in object storage, and mount It using s3fs-fuse project.

C. Use NVMe on HPC shapes to build a File Systemwith the RDMA connection.

D. Build a file-system using NVMe on Dense shapes. Then move the data to object storage when not needed.

Correct Answer: D

C. Distcp

D. Fast Connect

E. GoldenGate

Correct Answer: C

Question 6

Which workload is massively parallel In nature?

A. ETL

B. Streaming
