A company's IT team is responsible for a two-node active-passive cluster. They want to test the failover mechanism to ensure it works correctly. What is the safest way to test failover without risking data loss or a prolonged outage?

Run the failover test during peak business hours to see how the system behaves under load.

Test failover by unplugging the network cable from the active node without any prior preparation.

Skip the test because the cluster software is reliable and has been working without issues.

Perform the test during a scheduled maintenance window and ensure that a recent, verified backup is available.

What is a common impact of removing a node from a cluster?

The cluster requires a full reconfiguration from scratch

The services running on that node are automatically migrated to other nodes

The cluster automatically increases its quorum requirement

The cluster becomes read-only until the node is re-added

What is a common challenge when implementing high availability for stateful applications?

State must be replicated or shared across nodes

Stateful applications cannot be clustered

Stateful applications are inherently more secure

Stateful applications require more CPU resources

What is the primary purpose of a disaster recovery plan in the context of high availability?

To provide real-time failover for individual node failures

To ensure data is backed up regularly

To restore services after a catastrophic event affecting the entire cluster

To reduce the cost of the cluster infrastructure

A two-node active-passive cluster uses a shared storage array. Node A is the active node and Node B is the passive node. During a routine maintenance window, the administrator shuts down Node A cleanly. The cluster management software automatically fails over the service to Node B. After the maintenance is complete, the administrator wants to return the service to Node A. What is this process called and what is the primary consideration?

Reconfiguration; the administrator must remove Node A from the cluster and re-add it as a new node.

Failover; the administrator must manually copy all data from Node B back to Node A before restarting the service.

Quorum; the administrator must verify that Node A has a majority of votes before it can be reactivated.

Failback; the administrator must ensure Node A is fully synchronized with Node B's state before making it active again.
