In Junos multinode HA, what is the role of the control link?

It carries data traffic between the two nodes in the cluster.

It provides a backup path for data traffic if the primary data link fails.

It is used to synchronize configuration and maintain heartbeat communication between nodes.

It connects the cluster to the external network for management purposes.

In an SRX chassis cluster, a network administrator notices that the control link has failed. What is the immediate impact on the cluster?

The cluster nodes will not be able to synchronize configuration and session state.

Data-plane traffic will stop forwarding.

The nodes will reboot to recover the control link.

The cluster will immediately fail over to the standby node.

Which scenario best illustrates the value of multinode HA in a Junos security deployment?

Two devices are configured so that one takes over if the other experiences a hardware failure.

A single device is upgraded to a higher-capacity model to handle increased traffic.

A firewall is placed in-line to inspect all traffic entering the network.

Multiple security policies are created to segment traffic between different departments.

An engineer is configuring a new SRX chassis cluster. They have connected the control and fabric links between the two nodes. What is the next mandatory step in the initial configuration?

Enable the cluster on the management interface.

Set the node ID and cluster ID on both nodes.

Assign IP addresses to the fabric link interfaces.

Configure the redundancy group on the primary node only.

What is the first step in configuring a multinode HA cluster on Junos devices?

Configure the control and fabric links on both nodes.

Connect the nodes to the network and assign IP addresses to the interfaces.

Enable HA on both nodes and set the node ID for each device.

Configure the security policies that will be applied to the cluster.
