Which of the following is a capability enabled by VMware vCenter Server Appliance (VCSA)?

• A. VMware High Availability (HA)
• B. DNS resolution
• C. USB passthrough
• D. File sharing

Answer: (A)

The main idea here is that vCenter Server Appliance provides centralized management for a vSphere environment, and it is what enables coordinating features across multiple hosts. High Availability is a cluster-level capability in vSphere that automatically restarts virtual machines on other hosts when a host fails. Setting up and managing this behavior requires a central control point, which vCenter provides, so VCSA makes High Availability available to the entire cluster.

DNS resolution, USB passthrough, and file sharing aren’t features that are specifically enabled by VCSA in the same way. DNS is a network service typically provided by dedicated DNS servers, USB passthrough is a host/VM-level capability, and file sharing isn’t a core function managed by vCenter.
