CV0-004 Practice Question: Which THREE of the following are common causes of…
Which THREE of the following are common causes of VM migration failures in a cloud environment? (Choose three.)
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
✓
Incompatible CPU instruction sets or features between source and target hosts
Options B, D, and E are correct. Incompatible CPU instruction sets or features between source and target hosts (B) can cause migration failure because the VM may rely on specific CPU features. Insufficient storage space on the target host (D) prevents the VM's disk from being copied, leading to failure. Network connectivity issues between the source and target hypervisors (E) disrupt the data transfer required for migration. Option A is wrong: expired software licenses may affect compliance but are not a common cause of migration failures as licenses are typically per-VM or per-host. Option C is wrong: stale DNS records affect name resolution but do not directly impact the migration process, which uses IP addresses or hypervisor identifiers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Expired software licenses on the target host
Why it's wrong here
License checks are not typical causes; VMs carry their own licenses.
- ✓
Incompatible CPU instruction sets or features between source and target hosts
Why this is correct
Different CPU generations can prevent live migration.
- ✗
Stale DNS records for the VM's hostname
Why it's wrong here
DNS is not critical for hypervisor-level migration.
- ✓
Insufficient storage space on the target host
Why this is correct
Migration requires available storage for the VM.
- ✓
Network connectivity issues between the source and target hypervisors
Why this is correct
Migration traffic needs stable network.
