You are asked to create multiple virtual routers using a single SRX Series device. You must ensure that each virtual router maintains a unique copy of the routing protocol daemon (RPD) process.
Which solution will accomplish this task?
Correct Answer:
D
Logical systems on SRX Series devices allow the creation of separate virtual routers, each with its unique RPD process. This segmentation ensures that routing and security policies are isolated across different logical systems, effectively acting like independent routers within a single SRX device. For further information, see Juniper Logical Systems Documentation.
To create multiple virtual routers on a single SRX Series device, each with its own unique copy of the routing protocol daemon (RPD) process, you need to use logical systems. Logical systems allow for the segmentation of an SRX device into multiple virtual routers, each with independent configurations, including routing instances, policies, and protocol daemons.
✑ Explanation of Answer D (Logical System):
Configuration Example:
bash
set logical-systems
set logical-systems
Juniper Security Reference:
✑ Logical Systems Overview: Logical systems allow for the creation of multiple virtual instances within a single SRX device, each with its own configuration and control plane. Reference: Juniper Logical Systems Documentation.

In which mode is the SRX Series device?
Correct Answer:
C
How does an SRX Series device examine exception traffic?
Correct Answer:
A
Exception traffic, including management and control plane traffic, is handled by examining host-inbound traffic configurations at the ingress interface and zone. It ensures traffic reaches necessary services like SSH and IKE securely. See Juniper Host Inbound Traffic Documentation for more.
SRX Series devices handle exception traffic (such as management traffic like SSH, Telnet, DNS queries, etc.) differently than regular transit traffic. Exception traffic is examined based
on host-inbound traffic for the ingress interface and zone. If traffic is destined for the device itself (e.g., management traffic or routing protocol messages), it must be allowed as host-inbound traffic on both the ingress interface and zone.
Example Command: bash
set security zones security-zone trust host-inbound-traffic system-services ssh
This ensures that traffic destined to the SRX device is inspected based on the ingress interface and zone.

What is the advantage of using separate st0 logical units for each spoke connection?
Correct Answer:
D
Exhibit:
Referring to the exhibit, which statement is true?
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.
