Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check the compatibility of third-party VIBs with ESXi 8.0.
For a rolling upgrade of ESXi hosts from 7.0 to 8.0 using vLCM, you must check the compatibility of third-party VIBs with ESXi 8.0 (A). Additionally, the vCenter Server must be upgraded to 8.0 before upgrading ESXi hosts because vCenter manages the cluster (B). The VUM rollback feature, which is available in vLCM, should be configured to allow revert in case of failure (D). Option C is incorrect because hardware compatibility must be verified via the VMware Compatibility Guide (HCL), not assumed just because it is a major release. Option E is incorrect because vSphere DRS should be enabled to allow automated VM migration during host maintenance, not disabled.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Check the compatibility of third-party VIBs with ESXi 8.0.
Why this is correct
Incompatible VIBs can cause hosts to fail after upgrade.
- ✓
Ensure that the vCenter Server is upgraded to 8.0 before upgrading ESXi hosts.
Why this is correct
vCenter must be at the target version to manage upgraded hosts.
- ✗
Assume that all server hardware is supported by ESXi 8.0 since it is a major release.
Why it's wrong here
Hardware must be on the HCL; assumption can lead to failures.
- ✓
Verify that the VUM rollback feature is configured to allow revert in case of failure.
Why this is correct
Rollback is important for safety during upgrades.
- ✗
Disable vSphere DRS to prevent VM migration during host maintenance.
Why it's wrong here
DRS should be enabled to automatically migrate VMs off hosts entering maintenance mode.
