Question
An administrator would like to add a new server into an existing vSphere cluster. The servers are running Intel processors. The administrator needs to ensure that the new server can be added to the cluster with the same processor baseline as the existing servers. Which strategy should be used to achieve this goal?
Options
- AFault Tolerance
- BEnhanced vMotion Compatibility
- CvSphere vMotion
- DvSphere High Availability

Why each option
To add a new server to an existing vSphere cluster with Intel processors while ensuring processor baseline compatibility with existing servers, Enhanced vMotion Compatibility (EVC) should be used.
Fault Tolerance (FT) provides continuous availability for a VM by creating an identical copy and does not address CPU compatibility for new hosts.
Enhanced vMotion Compatibility (EVC) ensures CPU compatibility across different generations of Intel or AMD processors within a vSphere cluster. EVC does this by presenting a common, baseline CPU feature set to all virtual machines running on hosts in the cluster, even if the hosts have newer CPUs, allowing for seamless vMotion migrations between hosts with different CPU capabilities.
vSphere vMotion allows live migration of running virtual machines between ESXi hosts, but it does not address the underlying CPU compatibility requirements for adding new hosts to a cluster.
vSphere High Availability (HA) automatically restarts virtual machines on other hosts in the cluster if a host fails, and it does not address CPU compatibility for new hosts.
