An administrator is troubleshooting a chassis cluster where the active node is repeatedly failing over to the backup node every few minutes. The cluster logs show 'heartbeat timeout' messages. The control link is physically connected. What is the most likely cause of this issue?

The backup node has a higher priority.

The failover threshold is set too high.

The control link is experiencing intermittent errors or is flapping.

An administrator is troubleshooting a chassis cluster where the active node is not responding to management traffic. The backup node is healthy. What is the most likely cause of this issue?

The backup node has taken over the active role.

The active node has lost connectivity to the management network.

A network engineer is deploying a chassis cluster with two SRX devices. The requirement is that Node 1 should be the active node for all failover groups. What configuration ensures this behavior?

Configure the same priority on both nodes.

Assign Node 1 a higher cluster priority than Node 0.

Set the failover group threshold to 1 on Node 1.

Assign Node 0 a higher cluster priority than Node 1.

A security team is deploying a chassis cluster and wants to ensure that if the active node loses power, the backup node takes over with minimal disruption. What is the primary mechanism that enables this failover?

The active node sends a shutdown signal to the backup node before losing power.

The backup node is pre-configured to become active at a scheduled time.

The backup node periodically polls the active node's routing table.

The backup node continuously monitors the active node's heartbeat.

A network administrator is setting up a chassis cluster and wants to ensure that the node with the highest priority is always the active node, even after a failover and recovery. What configuration is required?

Set the failover threshold to 1.

Configure the same priority on both nodes.

Disable the heartbeat link on the backup node.

Enable preemption on the cluster.

Active Node Behavior (determination and Enforcement) JN0-637 Practice Questions (Page 2)

Part of the Multinode High Availability (HA) domain, which makes up ~22% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~8–13 in this domain), expect 1–2 from this objective — we provide 17 practice questions to prepare you well beyond it.
