What is required to form an active/passive cluster in Juniper?

A shared external storage device

A public IP address for each node

A dedicated control link between the two nodes

A separate management network for each node

A company runs an active/passive SRX cluster that handles VoIP traffic. The network team is concerned about call quality during a failover. They want to ensure that existing VoIP sessions are preserved during a failover. Which configuration is required to achieve this?

Enable session synchronization on the active node only.

Enable session synchronization and configure the cluster to synchronize application-specific sessions.

Enable the session synchronization feature only on the passive node.

Configure the cluster to use the control link for session synchronization.

An enterprise runs an active/passive SRX cluster. The active node experiences a complete power failure. The passive node detects the loss of the control link and the fabric link, and it fails over to become active. After the failed node is restored and rejoins the cluster, the network team observes that the original active node does not automatically reclaim the primary role. What is the most likely reason for this behavior?

The fabric link is not operational on the restored node, so it cannot participate in failover.

The restored node has a lower cluster priority than the current active node.

The cluster is configured with no-preempt, so the active node remains primary until a failure occurs.

The restored node's configuration is out of sync, so it cannot join the cluster as primary.

Why is session and state synchronization important in an active/passive HA cluster?

To enable both nodes to forward traffic simultaneously

To allow the passive node to take over existing sessions without interruption

To reduce the amount of traffic forwarded by the active node

To ensure the passive node has the same configuration as the active node

Which characteristic distinguishes active/passive HA mode from active/active mode in Juniper devices?

Both nodes forward traffic simultaneously in active/passive mode

Active/passive mode requires a dedicated management network

Active/passive mode uses a different routing protocol

Only one node forwards traffic at a time in active/passive mode

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 20 practice questions to prepare you well beyond it.
