VMware vSphere 7.x Professional for Service Providers — Question 4

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

Correct answer: B

Explanation

The correct answer is B because EVC (Enhanced vMotion Compatibility) mode must be enabled to allow VM migration between hosts with different CPU versions. The other options do not directly impact the migration capability related to hardware version compatibility.
