Question 1

A guest VM is reported to have poor storage performance. It has an I/O profile of 80% read. 20% write, and the HDDs form more than 50% of the read source. What should an administrator do to resolve this issue?
A) Increase SSD capacity
B) Increase the OPLOG
C) Increase the write cache
D) Use HDDs with higher RPM

Accepted Answer

Increasing SSD capacity can help improve read performance, especially since the VM has a high read I/O profile and more than 50% of the reads are coming from HDDs. By increasing SSD capacity, more read operations can be served from faster SSDs instead of slower HDDs.
