The correct answer involves reviewing the software FCoE/VLAN/driver versions in the cluster image and checking the vSphere Client cluster monitor for compliance details. When a host fails to remediate with a 'compliance error: host firmware mismatch' in a vLCM cluster, the mismatch is rarely about the firmware itself but rather about the image components—such as network driver or FCoE versions—that the firmware depends on, causing the host to report non-compliance. On the VCP-DCV exam, this question tests your understanding that vLCM enforces image-level consistency, and the cluster monitor provides the granular compliance data needed to pinpoint the exact component causing the mismatch. A common trap is assuming the error requires a firmware upgrade across all hosts, but the real issue is often a misaligned driver or protocol version within the cluster image. Remember the memory tip: "Firmware mismatch? Check the image components, not the firmware version."
VCP-DCV vSphere Lifecycle Management Practice Question
This VCP-DCV practice question tests your understanding of vsphere lifecycle management. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO troubleshooting steps should an administrator take when a host fails to remediate and shows 'compliance error: host firmware mismatch' in a vLCM cluster? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check the compliance status in the vSphere Client cluster monitor.
Options A and C are correct. Checking the vSphere Client cluster monitor provides details on compliance, and reviewing the software FCoE/VLAN/driver versions helps identify mismatches. Option B is incorrect because upgrading all hosts is too broad. Option D is incorrect because the error is about firmware, but the specific mismatch is likely due to image components. Option E is incorrect because disabling the cluster image is not a troubleshooting step.
Key principle: A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Remove the host from the cluster and re-add it.
Why it's wrong here
This is drastic and unlikely to fix the mismatch.
✗
Manually upgrade all hosts to the latest ESXi version.
Why it's wrong here
Manual upgrades bypass vLCM and may not resolve firmware mismatch.
✓
Check the compliance status in the vSphere Client cluster monitor.
Why this is correct
This shows which components are non-compliant.
Related concept
Access ports place end devices into a single VLAN.
✓
Review the software FCoE/VLAN/driver versions in the cluster image.
Why this is correct
Firmware mismatch often due to wrong driver version in the image.
Related concept
Access ports place end devices into a single VLAN.
✗
Disable the cluster image and use a baseline group instead.
Why it's wrong here
This is counterproductive and does not troubleshoot the issue.
Common exam traps
Common exam trap: an active trunk can still block the VLAN you need
A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.
Detailed technical explanation
How to think about this question
VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.
KKey Concepts to Remember
Access ports place end devices into a single VLAN.
Trunk ports carry multiple VLANs between switches.
Allowed VLAN lists decide which VLANs can cross a trunk.
Native VLAN mismatch can create confusing symptoms.
TExam Day Tips
→Use show vlan brief to verify access VLANs.
→Use show interfaces trunk to verify trunk state and allowed VLANs.
→Do not treat every same-VLAN issue as a routing problem.
Key takeaway
A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
Real-world example
How this comes up in practice
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
What to study next
Got this wrong? Here's your next step.
Review VLAN allowed lists, native VLAN mismatch detection, and how to verify VLAN membership with show vlan brief and show interfaces trunk. Then practise related VCP-DCV questions on switching, trunking, and access-port configuration.
