Network Topology

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
✓
Storage I/O error on the VM disk
Storage I/O errors on the VM disk can cause the hypervisor to pause the VM to prevent data corruption. CPU overcommitment (Option B) typically leads to performance degradation, not pausing. Insufficient memory (Option C) can cause swapping or OOM, but not directly pausing. A network interface being down (Option D) would affect connectivity, not cause the VM to enter a paused state.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Storage I/O error on the VM disk
Why this is correct
Hypervisors pause VMs when storage errors occur to prevent corruption.
- ✗
CPU overcommitment on the host
Why it's wrong here
High CPU ready time would slow VM, not pause it.
- ✗
Insufficient memory on the host
Why it's wrong here
Memory ballooning would occur, not pausing.
- ✗
Network interface is down
Why it's wrong here
Network issues don't affect VM state.
