VCP-DCV vSphere Lifecycle Management Practice Question
A company with a small vSphere environment has a single vCenter Server managing three ESXi hosts. The hosts are running ESXi 6.7 and the company wants to upgrade to ESXi 7.0. The vCenter Server is version 6.7 and runs on Windows. The administrator plans to use vSphere Update Manager (VUM) for the upgrade. The administrator attaches a baseline of ESXi 7.0 to the cluster and starts remediation. The remediation fails on all hosts with an error stating that the upgrade cannot be performed from a host that is part of a cluster. What is the likely issue?
⚠ Common exam trap
Watch out — candidates often assume VUM can upgrade ESXi hosts independently of the vCenter Server version, but VMware enforces a strict version dependency where the vCenter Server must be at the same or higher version than the ESXi hosts being upgraded.
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 vCenter Server must be upgraded to version 7.0 before upgrading the ESXi hosts.
VSphere Update Manager (VUM) requires the vCenter Server version to be equal to or higher than the ESXi version being applied. Since the vCenter Server is still running version 6.7, it cannot orchestrate an upgrade to ESXi 7.0. The vCenter Server must first be upgraded to version 7.0 before any ESXi 7.0 baseline can be attached and remediated against the 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 ESXi hosts are part of a cluster; VUM cannot remediate clustered hosts.
Why it's wrong here
VUM can remediate clustered hosts; maintenance mode is needed.
- ✗
vSphere DRS is not enabled on the cluster.
Why it's wrong here
DRS is not required for VUM upgrades.
- ✓
The vCenter Server must be upgraded to version 7.0 before upgrading the ESXi hosts.
Why this is correct
vCenter must be at or above the target ESXi version to manage upgrades.
- ✗
The hosts are not in maintenance mode; put them in maintenance mode and retry.
Why it's wrong here
The error is not about maintenance mode; the remediation process would handle that.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is planning to upgrade vCenter Server from 7.0 to 8.0 and then upgrade ESXi hosts from 7.0 Update 2 to 8.0. They have a vSAN cluster and use vSphere Lifecycle Manager (vLCM) with a single image. What is a critical prerequisite that must be verified before starting the vCenter Server upgrade?
medium- A.The vSAN cluster must be turned off to avoid data loss.
- B.All ESXi hosts must be updated to the latest ESXi 7.0 patch before upgrading vCenter.
- C.vSphere Update Manager (VUM) must be installed and configured.
- ✓ D.The vCenter Server version must be equal to or higher than the ESXi version being managed.
Why D: VCenter Server must be at a version equal to or higher than the ESXi hosts it manages. When upgrading from vCenter 7.0 to 8.0, the vCenter upgrade must complete first, as it will then be able to manage the ESXi 7.0 hosts during their subsequent upgrade to 8.0. Attempting to upgrade ESXi hosts before vCenter would violate this compatibility requirement and could cause management communication failures.
