EVC ensures vMotion compatibility across hosts with different CPU generations by exposing a uniform set of CPU features to all virtual machines in the cluster.

When converging an existing vSphere environment into VCF, certain architectural requirements must be satisfied.
The VCF 9.0 Convergence Guide states that:
The vCenter Server must be running on a cluster it manages (self-managed cluster) to allow SDDC Manager to take ownership during convergence.
Incorrect options:
Baselines (A) are not required; in fact, VCF requires image-based lifecycle management after convergence.
VDS version 7.0 (C) is not a documented prerequisite.
NSX (D) is not required prior to convergence; NSX can be deployed during workload domain bring-up.
Therefore, the required prerequisite is:
vCenter Server VM must be hosted on a cluster it manages.

The fully qualified domain name (FQDN) of the Aria Suite Lifecycle appliance and cluster are necessary for proper configuration and integration within the VMware Cloud Foundation environment. The password for the root account is required to authenticate and provide administrative access to the environment.
The password for the vcfadmin@local account is needed to perform administrative tasks related to VMware Cloud Foundation (VCF).

A CPU Reservation guarantees a minimum amount of CPU resources. A CPU Limit actually restricts the maximum CPU usage, HA Isolation Response deals with host isolation events, and TPS is memory- related.

In a VMware Cloud Foundation (VCF) environment, when adding a new cluster to an existing VI workload domain, the new cluster must use the same principal storage as the existing cluster. Since the existing cluster is using NFS, the available storage options for the new cluster would be NFS or vSAN, depending on the configuration.
