A network team is configuring an active/active chassis cluster. They want to ensure that if one node fails, the other node can take over the failed node's redundancy groups. What must be configured to allow this?

Redundancy groups with preempt enabled.

Redundancy groups with the same priority on both nodes.

Redundancy groups with both nodes as primary.

Redundancy groups with failover enabled.

What is a key characteristic of active/active HA mode compared to active/passive?

Only one node is active, and the other is a standby that does not process traffic.

Both nodes are actively processing traffic, which can increase overall throughput.

The nodes do not need to synchronize configurations because they operate independently.

Failover is faster because both nodes are always running.

In a chassis cluster, the active node loses power unexpectedly. The standby node has been monitoring the active node via the control link. What happens next?

The standby node becomes active for all redundancy groups after the heartbeat timeout.

The standby node sends an alert but does not take over.

The cluster remains down until the active node is restored.

The standby node reboots to re-establish the cluster.

An administrator is troubleshooting a chassis cluster that is not failing over as expected. They notice that the control link is up, but the fabric link is down. What is the most likely impact on failover?

Failover will not occur because the fabric link is required for heartbeats.

Failover will still occur, but existing sessions may be lost.

Failover will occur, but the new primary node will not have the configuration.

Failover will not occur because the cluster is not fully formed.

What software prerequisite must be met before configuring multinode HA on Junos devices?

The nodes must have a valid support contract to enable HA.

The nodes must be running the latest Junos version available.

The nodes must run different Junos versions to provide redundancy.

Both nodes must run the same Junos version and have the appropriate HA license.

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 27 practice questions to prepare you well beyond it.
