   An administrator is configuring an SRG on two SRX devices. The SRG will manage the 'nat' service. The administrator wants to ensure that the backup node can take over NAT sessions if the primary fails. What must be configured to enable session synchronization for the NAT service?

   • ASet the 'redundancy-mode' to 'active-active' for the SRG.
   • BUse the 'set security flow session-sync' command.
   • CConfigure 'nat' under the 'security' hierarchy on both nodes.
   • DEnable 'session-synchronization' under the SRG configuration.

   A network architect is designing a multinode HA solution for a pair of SRX devices. The requirement is to provide redundancy for a specific security service (e.g., IPS) without requiring full device-level failover. The architect wants to avoid the complexity of chassis clustering. Which approach should be taken?

   • AConfigure an SRG for the IPS service, specifying the primary and backup nodes.
   • BConfigure the IPS service on both nodes independently and use load balancing to distribute traffic.
   • CDeploy chassis clustering to provide redundancy for the IPS service.
   • DUse a routing protocol like VRRP to provide service redundancy.

   What event triggers a services redundancy group (SRG) to fail over services from the primary node to the backup node?

   • AThe primary node loses connectivity on a monitored interface
   • BThe primary node's CPU utilization exceeds 80%
   • CThe backup node sends a request to take over services
   • DThe primary node's configuration is modified

   What is a key difference between a services redundancy group (SRG) and chassis clustering on SRX Series devices?

   • ASRG is used for active/active configurations, while chassis clustering is used for active/passive
   • BSRG is a software feature, while chassis clustering is a hardware feature
   • CSRG requires a dedicated control link, while chassis clustering does not
   • DSRG provides redundancy for specific services, while chassis clustering provides redundancy for the entire device
