Referring to the exhibit, which statement is true?

SRG1 is configured in hybrid mode.

SRG1 is configured in hybrid mode.

The ICL is encrypted.

The ICL is encrypted.

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

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

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

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.

Juniper Security

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.
