VMware vSphere 6 Advanced Design (VCAP6-DCV Design) — Question 46

A solution architect has made the following design decisions:
✑ Leverage existing hardware that is certified on earlier versions of vSphere but is NOT on HCL for ESXi 6.5.
✑ Upgrade vCenter Server to version 6.5.
✑ Configure separate clusters based on ESXi versions 5.5, 6.0, and 6.5 for newly purchased, certified hardware.
✑ The underlying CPU family is compatible.
✑ There is enough resources available to vMotion virtual machines (VMs).
Given this scenario, what is the correct statement about the ability to vMotion virtual machines between versions of ESXi?

Answer options

• A. VMs created in vSphere 5.x must be upgraded first to newer virtual hardware and then be vMotioned to vSphere 6.x.
• B. VMs created in vSphere 6.x environment with default settings can be moved to ESXi 5.x.
• C. VMs can be vMotioned to the same or newer version of ESXi.
• D. VMs that are created after the vCenter Server 6.5 upgrade can be vMotioned between any supported versions of ESXi.

Correct answer: A

Explanation

The correct answer is A because virtual machines (VMs) created in vSphere 5.x need to be upgraded to newer virtual hardware before they can be vMotioned to a vSphere 6.x environment. Options B and D are incorrect as VMs cannot be moved backwards to an older ESXi version or without the necessary upgrades, while option C is misleading since it does not specify the requirement for virtual hardware upgrades for older VMs.
