What is the purpose of the cluster ID in a Junos HA cluster configuration?

To assign a unique IP address to each node.

To identify the cluster as a whole and ensure both nodes belong to the same cluster.

To determine the priority of the node in failover scenarios.

To specify the HA mode (active/passive or active/active).

A company runs an SRX HA cluster in active/passive mode. The primary node experiences a hardware failure that causes it to stop responding. The secondary node detects the failure and takes over as primary. However, the network team observes that some existing connections are dropped. What is the most likely reason for this?

The control link failed, preventing the secondary from receiving heartbeats.

The fabric link is down, so data cannot be forwarded between nodes.

The secondary node was ineligible, so it could not take over properly.

Session synchronization was not enabled, so the new primary does not have the session table.

What is the purpose of session synchronization in an HA cluster?

To synchronize the configuration between nodes.

To increase the number of sessions the cluster can handle.

To synchronize the routing table between nodes.

To ensure that existing sessions are not disrupted during a failover.

In a Junos HA cluster, what is the purpose of the control link?

To transmit data traffic between the two nodes.

To provide a backup path for data traffic.

To connect the cluster to the external network.

To exchange heartbeat messages and control information between the nodes.

What is a key characteristic of active/passive HA mode in Junos?

The active device and passive device both have their own separate configurations.

The passive device processes management traffic only.

The passive device maintains a synchronized configuration and session table but does not process traffic.

Both devices share the traffic load equally.

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 29 practice questions to prepare you well beyond it.
