In a multinode HA environment, which service must be configured to synchronize between nodes?

1. A. Advanced policy-based routing
2. B. PKI certificates
3. C. IPsec VPN
4. D. IDP

Correct Answer: B

You are configuring advanced policy-based routing. You have created a static route with next
hop of an interface in your inet.0 routing table


Referring to the exhibit, what should be changed to solve this issue?

1. A. You should change the routing instance type to virtual-router.
2. B. You should move the static route configuration to the main routing instance.
3. C. You should move the ine
4. D. o table before the routing instance table in your rib-groups configuration.
5. E. You should delete the interface-routes configuration under the routing-options hierarchy.

Correct Answer: C

Referring to the exhibit,

which two statements are correct about the NAT configuration? (Choose two.)

1. A. Both the internal and the external host can initiate a session after the initial translation.
2. B. Only a specific host can initiate a session to the reflexive address after the initial session.
3. C. Any external host will be able to initiate a session to the reflexive address.
4. D. The original destination port is used for the source port for the session.

Correct Answer: BD
Persistent NAT with target-host restricts session initiation to specific addresses, enhancing security. Reflexive NAT supports multiple connections by preserving the original port. Refer to Juniper NAT Configuration Documentation.
Referring to the NAT configuration shown in the exhibit:
✑ Specific Host Can Initiate a Session (Answer B): The configuration uses persistent NAT with the permit target-host-port statement. This allows a specific external host (based on the target host and port used in the initial session) to initiate a session back to the internal host after the initial session has been established.
* Explanation: Persistent NAT ensures that the translation state is maintained, allowing external hosts to connect back only under specific conditions (e.g., the same target host and port as used in the original connection).
✑ Original Destination Port (Answer D): The original destination port used by the
internal host is retained as the source port when the session is established from outside to inside. This behavior is a result of how persistent NAT binds the internal and external sessions, ensuring that communication occurs over the same port used for the initial session.

Exhibit:


Referring to the exhibit, which statement is true?

1. A. SRG1 is configured in hybrid mode.
2. B. The ICL is encrypted.
3. C. If SRG1 moves to peer 2, peer 1 will drop packets sent to the SRG1 interfaces.
4. D. If SRG1 moves to peer 2, peer 1 will forward packets sent to the SRG1 interfaces.

Correct Answer: D
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):
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.

You have cloud deployments in Azure, AWS, and your private cloud. You have deployed
multicloud using security director with policy enforcer to. Which three statements are true in this scenario? (Choose three.)

1. A. You can run Juniper ATP scans only on traffic from your private cloud.
2. B. You can run Juniper ATP scans for all three domains.
3. C. You must secure the policies individually by domain.
4. D. The Policy Enforcer is able to flag infected hosts in all three domains.
5. E. You can simultaneously manage the security policies in all three domains.
