Which command is often used to verify the status of an HA cluster?

The command that is commonly used to verify the status of an HA cluster is "show system ha." This command provides detailed insights into the High Availability (HA) configuration and the operational status of the cluster members. When executed, it displays key information about the cluster, such as the state of each member (active or standby), the cluster's health, and the synchronization status between cluster members. This information is crucial for network administrators to ensure that the HA setup is functioning correctly and that failover mechanisms are in place and ready to activate if needed.

Other options, while they may offer insights into the system or HA configuration, do not specifically target the status of an HA cluster as directly or comprehensively as "show system ha." For instance, "get system ha status" may be used to see certain details about the HA state, but "show system ha" offers a more detailed picture of the overall cluster status, making it the more effective choice for this verification task.
