What minimum size of block volume with Balanced performance tier maximizes throughput for large files?

• A.10TB
• B.32TB
• C.100GB
• D.1TB

A customer ran a Job on 2 BM.HPC2.36, and the job took 4 hours using 32 cores of each node. They later ran on 4 nodes and the Job took 3 hours. What Is the efficiency gained?

• A.100%
• B.75%
• C.50%
• D.66%

A customer is hesitating between running BM.Standard.E3.128 or HPC2.36 for his workload. Which statement would disqualify the AMD chip without any benchmark?

• A.The workload requires about 4GB/core of memory.
• B.The workload is embarrassingly parallel.
• C.Total number of processes is between 48 and 128 cores and can use RDMA.
• D.IO speed has a huge impact.

On Oracle Cloud Infrastructure (OCI), a customer wants to build a 3TB 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 three Block volumes of 1TB each and use filesystem Block size of 4K.
• B.Attach one Block volume of 3TB volume size and use filesystem Block size of 2M or higher.
• C.Attach one Block volume of 3TB volume size and use filesystem Block size of 4K.
• D.Attach three Block volumes of 1TB each and use filesystem Block size of 2M or higher.

A customer wants to store small files (KBs) workload in a filesystem.
What two options should you use to measure performance for this filesystem?

• A.High IOPS
• B.Amount of Memory on file servers
• C.CPU processor clock speed for faster processing
• D.Low Latency
