A company is deploying an SRX HA cluster across two geographically separated data centers for disaster recovery. They want to use active/passive mode. What is a critical consideration for this deployment?

The control link must have low latency and high reliability, which may require a dedicated WAN connection.

Active/passive mode is not supported across geographic distances.

The two nodes must be in the same broadcast domain to form a cluster.

The cluster will automatically fail over if the WAN link between the sites goes down.

A company is deploying an SRX HA cluster with two different models: SRX345 and SRX550. Both have the same software version and licenses. What is the most important consideration for this deployment?

The two models can form a cluster if they have the same license features.

The two models must have the same hardware specifications to form a cluster.

The two models can form a cluster as long as they run the same software version.

The two models can form a cluster if they have the same number of interfaces.

An SRX HA cluster is configured to synchronize configuration and sessions. The administrator notices that after a failover, some sessions are not preserved. What is the most likely cause?

The security policies are not identical on both nodes.

The cluster is in active/active mode, which does not support session synchronization.

The control link is congested with data traffic.

The fabric link is down, so session synchronization is not occurring.

An administrator needs to upgrade the software on an active/passive SRX HA cluster with minimal downtime. The cluster is currently running a stable version, and the upgrade requires a reboot. What is the recommended maintenance procedure?

Upgrade the active node first, then the standby node after the active reboots.

Upgrade both nodes simultaneously to save time, then reboot the cluster.

Upgrade the standby node first, then force a failover to make it active, and upgrade the new standby.

Disable the cluster, upgrade both nodes, and then re-enable the cluster.

An administrator is configuring an active/passive HA cluster on SRX devices. They want to ensure that when a failover occurs, existing user sessions are preserved so that users do not have to re-authenticate. What must be configured to achieve this?

Use the same interface IP addresses on both nodes

Set the failover threshold to a low value

Enable session synchronization on the fabric link

Configure the same security policies on both nodes
