Which component needs to be available for the ESXi hosts to be able to enable vSphere High Availability?

Question

Options

• A10Gbps network interfaces
• BDirect attached disks
• CShared data storage
• DDual CPU sockets

Explanation

vSphere High Availability works by restarting virtual machines on surviving hosts when a host fails, which requires all cluster hosts to access the same VM files - only possible with shared data storage (such as a SAN, NAS, or vSAN datastore). Without a common shared datastore, surviving hosts have no path to the VM disk and configuration files needed to restart workloads.

Why the distractors are wrong:

• A (10Gbps NICs): HA functions on standard 1Gbps networks; higher bandwidth improves performance but is not a requirement.
• B (Direct attached disks): Local/direct-attached storage is the opposite of what HA needs - it's host-specific and inaccessible to other cluster members.
• D (Dual CPU sockets): CPU socket count is irrelevant to HA; the feature has no hardware topology requirement beyond cluster membership.

Memory tip: Think of HA as a "rescue operation" - the rescue team (surviving hosts) can only save the passengers (VMs) if they can reach the vehicle (shared storage). No shared storage = no rescue.
