Final answer:
It is recommended to have a backup Master Node configured in hot-standby to ensure high availability and prevent downtime in case the Cluster Master fails or is unreachable.
Step-by-step explanation:
The statement is true. It is recommended to have a backup Master Node configured in hot-standby to take over cluster coordination in case the Cluster Master fails or is unreachable. This helps ensure high availability and prevent downtime in the event of a failure.
Having a backup Master Node allows for uninterrupted cluster coordination and ensures that the cluster is still able to function even when the primary Master Node is down. The backup node can take over the responsibilities of the primary Master Node, such as coordinating cluster operations and managing resources.
Having a hot-standby configuration also provides fault tolerance and helps in disaster recovery scenarios. This means that if the primary Master Node fails, the backup Master Node can quickly and seamlessly take over, reducing the impact on the overall system.
