The cluster ping-cluster command is specifically designed to testinter-node cluster network connectivity, includinglatency, packet loss, and throughputbetween cluster nodes. This command generates synthetic traffic over the cluster interconnect and measures performance characteristics that directly affect cluster health and stability.

The command is commonly used duringpost-installation validation, cluster expansion, and troubleshooting scenarios involving cluster network performance. It provides insight into whether the cluster interconnect is operating within expected parameters.

Other commands listed do not provide this functionality. QoS workload statistics focus on application-level performance, network test-path validates reachability for LIF failover paths, and statistics node show reports internal node counters rather than inter-node network performance.

Therefore, the correct answer isB.

The root aggregate hosts system volumes such as vol0. Adding data volumes can negatively impact system operations, causing performance and stability issues.
