NEW QUESTION 3
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 (esxOT esx02. esx03 and esx04) that utilize Intel Skylake-based CPUs. The two new hosts (esx05 and esx06) are configured 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?

• A. Create a new vSphere cluster with Enhanced vMotion Compatibility (EVC) enabled and move all hosts into A' 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

Answer: C

Explanation:
The step that the administrator should take to meet these requirements is to configure Enhanced vMotion Compatibility (EVC) mode on the existing cluster and add the two new hosts into the cluster. EVC mode allows migration of virtual machines between different generations of CPUs by masking unsupported processor features. EVC mode can be enabled on an existing cluster without affecting powered-on virtual machines. References:
