VMware vSphere 8.x Professional — Question 95

An administrator is tasked with adding two additional hosts into an existing production vSphere cluster to support the need for additional capacity.

The vSphere cluster currently has four identically configured ESXi hosts (esx01, esx02, esx03 and esx04) that utilize Intel Skylake-based CPUs. The two new hosts (esx05 and esx06) are con-figured identically in terms of memory and storage to the existing hosts, but utilize Intel Ice Lake-based CPUs.

The administrator must ensure that:

• Any virtual machine migrates to any of the six ESXi hosts running in the cluster.
• There is no virtual machine downtime during the process of adding the new hosts.

Which step should the administrator take to meet these requirements?

Answer options

• A. Create a new vSphere cluster with Enhanced vMotion Compatibility (EVC) enabled and move all hosts into the new cluster.
• B. Create a new vSphere cluster and move only three hosts into the new cluster.
• C. Configure Enhanced vMotion Compatibility (EVC) mode on the existing cluster and add the two new hosts into the cluster.
• D. Create a new vSphere cluster with vSphere High Availability (HA) enabled and move all hosts into the new cluster.

Correct answer: C

Explanation

The correct answer is C because configuring Enhanced vMotion Compatibility (EVC) allows for CPU compatibility across different generations, enabling virtual machines to migrate seamlessly between all six hosts. Options A and B suggest creating a new cluster, which would disrupt existing virtual machine operations and not meet the requirement for zero downtime. Option D focuses on High Availability, which does not address the CPU compatibility needed for migration.
