Exhibit:





Referring to the exhibit, which two statements are correct? (Choose two.)

  1. The ge-0/0/3.0 and ge-0/0/4.0 interfaces are not active and will not respond to ARP requests to the virtual IP MAC address.
  2. This device is the backup node for SRG1.
  3. The ge-0/0/3.0 and ge-0/0/4.0 interfaces are active and will respond to ARP requests to the virtual IP MAC address.
  4. This device is the active node for SRG1.

Answer(s): A,B

Explanation:

The interfaces are active and respond to ARP for virtual IP as long as the node is the primary or active node in the SRG group. This ensures high availability and proper traffic forwarding. For information, refer to Juniper SRX HA Documentation.

The exhibit shows information about a chassis cluster and its services redundancy group (SRG1). Let's analyze the relevant details:

Explanation of Answer B (Backup Node for SRG1):
The exhibit indicates that this SRX device is in the backup role for SRG1. The status: BACKUP field confirms that this device is currently in a standby role and is not the active node for the services redundancy group.
Explanation of Answer A (Interfaces Not Active):
Since the device is in the backup role, the interfaces ge-0/0/3.0 and ge-0/0/4.0 will not respond to ARP requests for the virtual IP's MAC address. Only the active node's interfaces respond to ARP requests in a chassis cluster configuration.

Reference:

Chassis Cluster Redundancy Overview: In a chassis cluster, the backup node does not respond to ARP requests for the virtual IP. Only the active node handles such requests to ensure seamless traffic forwarding.

Which role does an SRX Series device play in a DS-Lite deployment?

  1. Softwire concentrator
  2. STUN server
  3. STUN client
  4. Softwire initiator

Answer(s): A



Which two statements are correct about the ICL in an active/active mode multinode HA environment? (Choose two.)

  1. The ICL is strictly a Layer 2 interface.
  2. The ICL uses a separate routing instance to communicate with remote multinode HA peers.
  3. The ICL traffic can be encrypted.
  4. The ICL is the local device management interface in a multinode HA environment.

Answer(s): B,C



Exhibit:



Your company uses SRX Series devices to establish an IPsec VPN that connects Site-1 and the HQ networks. You want VoIP traffic to receive priority over data traffic when it is forwarded across the VPN.
Which three actions should you perform in this scenario? (Choose three.)

  1. Enable next-hop tunnel binding.
  2. Create a firewall filter that identifies VoIP traffic and associates it with the correct forwarding class.
  3. Configure CoS forwarding classes and scheduling parameters.
  4. Enable the copy-outer-dscp parameter so that DSCP header values are copied to the tunneled packets.
  5. Enable the multi-sa parameter to enable two separate IPsec SAs for the VoIP and data traffic.

Answer(s): B,C,E
