CV0-003 · Question #128
Fault tolerant design allows a host to overcome a single HBA failure through:
The correct answer is A. clustering. Clustering provides host-level fault tolerance by allowing workloads to fail over to a surviving cluster node when a host's HBA fails, maintaining service continuity.

Why each option
Clustering provides host-level fault tolerance by allowing workloads to fail over to a surviving cluster node when a host's HBA fails, maintaining service continuity.
Clustering groups multiple hosts so that if one host suffers an HBA failure, the cluster automatically redirects and restarts workloads on a healthy node, effectively overcoming the single point of failure and maintaining availability without interruption.
UTA (Unified Target Adapter) pairing is a configuration method for converged network adapters and does not provide fault tolerance mechanisms for HBA failures.
Multipathing provides redundant I/O paths between a single host and storage at the fabric level, but is a path-redundancy mechanism rather than a host-level fault tolerance solution that overcomes a complete HBA failure.
NIC teaming provides Ethernet network interface redundancy for LAN connectivity, not fault tolerance for HBA failures in a storage fabric.
