Which functions are provided by server-based storage virtualization? (Select two.)

Host path failover is a core function of server-based virtualization software, which monitors multiple paths to storage and automatically reroutes I/O to an alternate path if the active path fails, ensuring continuous availability.

Volume sharing among multiple servers requires network-based or array-based virtualization, since server-based virtualization is scoped to a single host's view of storage and cannot coordinate shared access across hosts.

Performance load balancing of SAN connections is provided by server-based virtualization because the host-resident software can distribute I/O across all available SAN paths to maximize throughput and prevent bottlenecks.

Intelligent LUN expansion and reduction is an array-based virtualization function controlled by the storage array controller firmware, not by software running on the host.

Thin provisioning is an array-level or hypervisor-level feature that allocates physical capacity on demand behind a virtual disk, and is not a function provided by server-based storage virtualization software.
