What happens if the control link fails in a chassis cluster?

The cluster continues to operate normally without any impact

The cluster automatically shuts down to prevent data corruption

The nodes immediately fail over all redundancy groups to the secondary node

The nodes may enter a split-brain condition if the fabric link is also down

A chassis cluster is running with node0 as primary for all redundancy groups. The control link goes down, and the fabric link remains up. The administrator wants to ensure that the cluster continues to operate without a split-brain scenario. What is the best course of action?

Disable the fabric link to force a failover.

Reboot node0 to force a failover.

Do nothing; the cluster will automatically failover to node1.

A chassis cluster is running with node0 as primary for all redundancy groups. The control link between the nodes goes down, but the fabric link remains up. What is the expected behavior of the cluster?

The cluster will continue to operate normally, with node0 as primary.

The cluster will enter a split-brain state, with both nodes acting as primary.

The cluster will remain operational, but the fabric link will be used for control traffic.

The cluster will failover to node1, making it primary for all redundancy groups.

Which configuration statement is used to enable a chassis cluster on a Junos device?

set high-availability cluster enable

Which statement about the fabric link is true?

It is used to connect the cluster to the upstream network

It can be used as a backup for the control link if the control link fails

It is used only for control plane communication

It is optional if the control link is operational

Chassis Cluster Characteristics and Operation JN0-336 Practice Questions (Page 2)

Part of the High Availability (HA) Clustering domain, which makes up ~14% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–8 in this domain), expect 1–2 from this objective — we provide 21 practice questions to prepare you well beyond it.
