An administrator is configuring a new SRX HA cluster. They have set the cluster ID to 1 and node IDs to 0 and 1. They have also configured the control link and fabric link. What else must be configured to ensure that the cluster can synchronize configuration changes?

Configure the cluster's virtual IP addresses on the data interfaces.

Ensure that both nodes have the same software version and license.

Enable configuration synchronization on both nodes.

Set the same root password on both nodes.

An SRX HA cluster is in active/passive mode. The active node loses power unexpectedly. The standby node takes over, but the administrator notices that some sessions are lost. What is the most likely reason?

The security policies were not synchronized.

Session synchronization was not enabled or the fabric link was down.

The standby node was not rebooted after the failover.

The control link was not configured.

A service provider wants to deploy two SRX devices to provide firewall services for two separate customer segments. Each segment requires its own set of security policies and should continue to operate even if one device fails. The provider has a limited budget and wants to use both devices efficiently. Which HA deployment mode should they choose?

Active/active with both nodes handling the same traffic load

Active/active with each node handling a different customer segment

Active/passive with failover only on the control link

Active/passive with both nodes in the same security zone

An SRX HA cluster is operating in active/passive mode. The active node experiences a hardware failure and the standby node takes over. After the failed node is repaired and brought back online, what is the default behavior regarding the cluster's active role?

The repaired node becomes active only if the administrator configures preemption.

The cluster remains active on the current node, and the repaired node joins as standby.

The repaired node automatically becomes active again because it has a lower node ID.

The cluster requires a manual reboot of both nodes to re-establish the original active/passive roles.

An SRX HA cluster is experiencing frequent failovers. The administrator suspects that the control link is flapping. What should the administrator check first?

The session synchronization settings on the fabric link

The physical cable and interface status of the control link

The routing protocol configuration on the data interfaces

The security policy configuration on both nodes

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 12 practice questions to prepare you well beyond it.
