Final answer:
It is considered best practice to invoke maintenance-mode prior to initiating a cluster rolling-restart.
Step-by-step explanation:
The statement 'It is considered best practice to invoke maintenance-mode prior to initiating a cluster rolling-restart' is true.
Maintenance mode is a feature in cluster management systems that enables administrators to perform maintenance tasks on individual nodes or the entire cluster without affecting service availability. When maintenance mode is invoked, the cluster redistributes workload from the nodes in maintenance to other nodes, ensuring uninterrupted service.
A cluster rolling-restart is a planned restart of cluster nodes, one at a time, to apply configuration changes, software updates, or other maintenance tasks. By invoking maintenance mode before a rolling-restart, administrators ensure that the workload is properly redistributed and services remain available throughout the restart process.
