   What is the function of the fabric link in a Junos multinode HA cluster?

   • AIt is used exclusively for heartbeat messages between the nodes.
   • BIt connects the cluster to the internet for firmware updates.
   • CIt carries data traffic between the nodes when one node needs to forward traffic to the other.
   • DIt provides a redundant path for control traffic if the control link fails.

   A company is considering a chassis cluster to provide high availability for their data center. They have a requirement that if one node fails, the other node must be able to handle the entire traffic load. What should they verify before deployment?

   • AThe fabric link is configured with a high bandwidth.
   • BThe control link is redundant.
   • CThe cluster is configured in active/active mode.
   • DThe standby node has sufficient capacity to handle the full traffic load.

   A company is deploying a chassis cluster to support both active/active and active/passive services. They want to use active/active for their web traffic and active/passive for their VPN traffic. How can this be achieved?

   • AUse a single redundancy group for all traffic and configure it as active/active.
   • BAssign the web traffic to redundancy group 1 and the VPN traffic to redundancy group 2, with both groups active on different nodes.
   • CUse two redundancy groups: one for web traffic (active/active) and one for VPN traffic (active/passive), with appropriate priorities.
   • DAssign the web traffic to redundancy group 1 and the VPN traffic to redundancy group 2, with both groups active on the same node.

   An administrator has an active/active chassis cluster with two redundancy groups. Redundancy group 1 is primary on node 0, and redundancy group 2 is primary on node 1. The fabric link fails. What is the impact on the cluster?

   • AThe cluster will fail over both redundancy groups to node 1.
   • BThe cluster will fail over both redundancy groups to node 0.
   • CThe cluster will reboot both nodes to re-establish the fabric link.
   • DBoth nodes will continue to forward traffic for their respective redundancy groups, but session synchronization will be lost.

   A network engineer is planning to deploy a two-node SRX chassis cluster. The two SRX devices are different models: one is an SRX340 and the other is an SRX345. Both run the same Junos version and have the same license. What is the most likely issue with this deployment?

   • AThe cluster will form but only one node will be active at a time.
   • BThe cluster will form but the fabric link will not come up.
   • CThe cluster will form but only the SRX345 can be the primary node.
   • DThe cluster will not form because the nodes must be the same model.
