Configuration Basics

You are designing highly available SRX Series devices for your data center. Any failure on the active firewall must trigger a move of all services to the non-active firewall.

What will achieve this requirement?

  • A Place both nodes in a Virtual Chassis.
  • B Place all interfaces in the SRX cluster in RG0 and use interface monitoring.
  • C Remove RG0 from the SRX cluster and place all interfaces in RG1 and use interface monitoring.
  • D Install redundant chassis cluster cards in each node and disable one.
Explanation

Redundancy group 0 (RG0) controls which Routing Engine is primary in an SRX chassis cluster. An RG0 failover performs a Routing Engine failover, moving the control plane and restarting all processes on the new primary node. Interface monitoring can trigger redundancy-group failover when monitored-interface failure reduces the group threshold to zero. RG0 is mandatory in a chassis-cluster configuration.
