A Pacemaker cluster administrator is configuring STONITH for a cluster with nodes that have IPMI-based BMCs. The administrator has created a fence device resource for each node. Which additional configuration is REQUIRED to ensure that fencing works correctly?

Configure a watchdog device on each node.

Set the 'stonith-enabled' cluster property to true.

Set the 'no-quorum-policy' to 'ignore'.

Create a location constraint for each fence device.

A Pacemaker cluster has a node that is experiencing intermittent hardware issues. The administrator wants to configure the cluster to automatically detect and fence the node when its health check fails. Which approach should be used?

Configure a resource agent that monitors node health and updates a node attribute, then create a location constraint that fences the node when the attribute indicates failure.

Set the 'node-health' cluster property to 'enabled'.

Configure a STONITH resource that monitors node health and fences the node on failure.

A Pacemaker cluster is experiencing unexpected resource failovers. The administrator suspects that the cluster is not correctly determining which node should be the Designated Coordinator (DC). Which component is responsible for electing the DC?

The Local Resource Management daemon (LRMd) elects the DC.

The Cluster Resource Management daemon (CRMd) on each node participates in the election process.

The Policy Engine (PEngine) on each node elects the DC.

The STONITH daemon (STONITHd) elects the DC.
