VMware vSphere 7.x Professional (VCP-DCV 2021) — Question 8

A cluster of vSphere 6.5 and 6.7 hosts all have identical hardware. VMs are created on the 6.7 hosts with virtual hardware version 14. During routine maintenance on the 6.7 hosts, the VMs are unable to migrate to the 6.5 hosts.
Why are the VMs unable to migrate to the 6.5 hosts?

Answer options

• A. The virtual hardware version is incompatible with 6.5
• B. VMware Tools version is upgraded
• C. EVC mode is disabled
• D. DPM is configured incorrectly

Correct answer: A

Explanation

The correct answer is A because the virtual hardware version 14 is not compatible with vSphere 6.5, which only supports up to version 13. Option B is incorrect as the VMware Tools version does not affect VM compatibility for migration. Option C is not relevant here since EVC mode affects CPU compatibility, not virtual hardware version. Option D is also incorrect since DPM is unrelated to the virtual hardware versions.
