CV0-004 Troubleshooting Practice Question
A cloud administrator is troubleshooting a virtual machine that is experiencing high memory usage. The VM is running a web server. Which two metrics should the administrator monitor to determine if the VM needs additional memory? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Swap usage
Options A and D are correct. Available memory directly shows the amount of free RAM, and swap usage indicates that the OS is using disk as memory, which is a sign of insufficient physical memory. Disk I/O wait (B) is a disk performance metric, page fault rate (C) is a memory metric but is less direct than swap usage for determining if more memory is needed, and CPU ready time (E) is a CPU metric.

For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Swap usage
Why this is correct
High swap usage indicates the OS is using disk as memory, a sign of insufficient physical memory.
- ✗
Disk I/O wait
Why it's wrong here
Disk I/O wait indicates disk performance issues, not memory.
- ✗
Page fault rate
Why it's wrong here
Page fault rate can indicate memory pressure but is less direct than available memory and swap usage.
- ✓
Available memory
Why this is correct
Available memory shows how much free memory is available; low available memory suggests need for more RAM.
