Answers
C.

If SRG1 moves to peer 2, peer 1 will drop packets sent to the SRG1 interfaces.

D.

If SRG1 moves to peer 2, peer 1 will forward packets sent to the SRG1 interfaces.

Answers
D.

If SRG1 moves to peer 2, peer 1 will forward packets sent to the SRG1 interfaces.

Suggested answer: D

Explanation:

The exhibit describes a Chassis Cluster configuration with high availability (HA) settings. The key information is related to Service Redundancy Group 1 (SRG1) and its failover behavior between the two peers.

Explanation of Answer D (Packet Forwarding after Failover):

In a typical SRX HA setup with active/backup configuration, if the SRG1 group moves to peer 2 (the backup), peer 1 (previously the active node) will forward packets to peer 2 instead of dropping them. This ensures smooth failover and seamless continuation of services without packet loss.

This behavior is part of the active/backup failover process in SRX chassis clusters, where the standby peer takes over traffic processing without disruption.

Reference:

Chassis Cluster Failover Behavior: When a service redundancy group fails over to the backup peer, the previously active peer forwards traffic to the new active node. Reference: Juniper Chassis Cluster Documentation.
