When working with hypervisors configured in a highly available configuration that provides fail- over capabilities to virtualized servers and applications, which of the following requirements is commo

Storage allocation - specifically shared storage such as SAN or NFS - is a well-known and heavily documented HA prerequisite that administrators routinely configure and verify during HA setup.

CPU allocation and affinity settings are standard HA planning items covered in all major hypervisor HA documentation and vendor best practices guides.

Memory allocation and memory reservations are explicitly required during VM configuration and are a standard step in any HA cluster validation checklist.

When a virtualized server fails over to a different physical host in an HA cluster, the operating system and application licenses may be host-bound or limited by core/socket counts on the target host. Administrators frequently configure CPU, memory, and storage correctly but neglect to verify that license agreements and activation servers permit operation on the failover node, potentially causing compliance violations or application failures post-failover.
