VCP-DCV vSphere Lifecycle Management Practice Question
A company has a vSphere cluster with 10 ESXi hosts managed by vLCM. They use a custom image that includes a third-party network driver. After updating the image to include a new version of the driver, remediation fails on all hosts with the error: 'The software specification contains a VIB that is not compatible with the host platform.' What is the most likely cause?
⚠ Common exam trap
Many candidates assume the error is about signing or corruption, but vLCM specifically checks VIB-to-platform compatibility at the VIB metadata level, not the image's signature or depot integrity.
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 new driver VIB is not compatible with the ESXi version in the image.
The error 'The software specification contains a VIB that is not compatible with the host platform' indicates that the VIB (vSphere Installation Bundle) in the custom image is not designed to run on the ESXi version specified in the image. vLCM validates VIB compatibility against the ESXi base image version, and a third-party driver VIB must be built for that exact ESXi build. Since the new driver version is incompatible with the ESXi version, remediation fails on all hosts.
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 new driver VIB is not compatible with the ESXi version in the image.
Why this is correct
The VIB must match the ESXi build; an incompatible version causes this error.
- ✗
The vLCM image depot is corrupted.
Why it's wrong here
Corruption would cause import errors, not compatibility issues.
- ✗
The hosts have incompatible firmware.
Why it's wrong here
Firmware incompatibility would produce a different error message.
- ✗
The custom image is not signed by VMware.
Why it's wrong here
Unsigned VIBs are allowed if added to the software depot; this would not cause that specific error.
