   In a chassis cluster, the control link is down, but the fabric link is operational. What is the most likely outcome?

   • AThe cluster will immediately fail over to the standby node.
   • BThe cluster will reboot both nodes.
   • CData-plane traffic will be disrupted.
   • DThe cluster will continue to operate, but configuration changes will not be synchronized.

   A security team is configuring an active/active chassis cluster for two SRX devices. They want to ensure that both nodes actively forward traffic for different redundancy groups. Which statement is true about this configuration?

   • AEach node can be primary for a different redundancy group, allowing both to forward traffic.
   • BBoth nodes must be primary for all redundancy groups simultaneously.
   • COnly one node can forward traffic at a time, regardless of redundancy group configuration.
   • DThe fabric link is not required in active/active mode.

   A company is deploying a pair of SRX devices in an active/passive cluster to provide high availability for their internet edge. They want to minimize the failover time when the active node fails. Which mechanism is most effective in reducing failover time?

   • AConfiguring the cluster in active/active mode.
   • BUsing a longer heartbeat interval.
   • CEnabling session synchronization on the fabric link.
   • DIncreasing the number of redundancy groups.

   Which of the following is a hardware requirement for deploying multinode HA on Junos security platforms?

   • AThe nodes must be connected to the same switch for the control link.
   • BBoth nodes must be the same model and have the same hardware specifications.
   • CEach node must have a dedicated management interface for HA communication.
   • DThe nodes must be in the same physical location to ensure low latency.

   What is a primary benefit of deploying multinode high availability (HA) on Junos security platforms?

   • AIt eliminates the need for a separate management network by using the data plane for all control traffic.
   • BIt simplifies configuration by allowing all nodes to share a single configuration file that is automatically synchronized.
   • CIt increases the throughput of a single security device by combining the processing power of multiple nodes.
   • DIt provides network resilience by allowing a second node to take over traffic processing if the primary node fails.
