VCP-DCV vSphere Lifecycle Management Practice Question
An administrator manages a vSphere 7.0 U2 cluster with 20 hosts. The cluster uses vLCM image-based management and vSphere DRS. The administrator applies a new image with ESXi 7.0 U3 and additional driver VIBs. During remediation, one host fails to reboot after the upgrade. The host is now unresponsive via vCenter, but can be pinged. The administrator connects to the host's DCUI and sees a purple screen with a PSOD error referencing 'Unsupported VIB' and 'vmkcswap'. What is the most likely cause?
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
✓
The vmkcswap VIB included in the image is not compatible with ESXi 7.0 U3.
The PSOD error referencing 'Unsupported VIB' and 'vmkcswap' clearly indicates that the vmkcswap VIB included in the vLCM image is not compatible with ESXi 7.0 U3. vLCM applies images directly; if a VIB is unsupported, it can cause a failure during reboot. Option A is correct. Option B is incorrect because the image did include the vmkcswap VIB, but incompatibility caused the issue. Option C is incorrect as no hardware fault is indicated. Option D is incorrect because network misconfiguration would not produce a PSOD referencing an unsupported VIB.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The vmkcswap VIB included in the image is not compatible with ESXi 7.0 U3.
Why this is correct
VIBs must be validated for the target ESXi version; otherwise, they cause failures.
- ✗
The image did not include the necessary vmkcswap VIB.
Why it's wrong here
The PSOD says 'Unsupported VIB', indicating it was included but not supported.
- ✗
The host has a hardware fault causing the PSOD.
Why it's wrong here
The PSOD error points to a VIB issue, not hardware.
- ✗
The host's network configuration is incorrect for the new version.
Why it's wrong here
Network misconfiguration would not cause a PSOD referencing a VIB.
