Question No. 1

Which two elements are necessary to configure a rule under an APBR profile? (Choose Two)

Show Answer Hide Answer
Correct Answer: B, C

Here's why those elements are necessary for configuring a rule under an APBR profile:

B . Match condition: This defines the criteria for matching traffic to the APBR rule. It can include:

Applications: Match based on specific applications or application groups.

URL categories: Match based on URL categories provided by a web filtering service.

Other criteria: You can also match based on source/destination IP addresses, ports, protocols, etc.

C . Then action: This specifies the action to take when traffic matches the rule. The primary action in APBR is:

routing-instance: This redirects the matching traffic to a specific routing instance, allowing you to steer traffic through different paths based on the application or URL category.

Why other options are incorrect:

A . Instance type: While routing instances are used in APBR, the 'instance type' itself is not configured within the APBR rule. You define the instance type separately when configuring the routing instance.

Question No. 4

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

Show Answer Hide Answer
Correct Answer: A

Question No. 5

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?

Show Answer Hide Answer
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):

A logical system on an SRX device enables you to create multiple virtual instances of the SRX, each operating independently with its own control plane and routing processes. Each logical system gets a separate copy of the RPD process, ensuring complete isolation between virtual routers.

This is the correct solution when you need separate routing instances with their own RPD processes on the same physical device.

Configuration Example:

bash

set logical-systems <logical-system-name> interfaces ge-0/0/0 unit 0

set logical-systems <logical-system-name> routing-options static route 0.0.0.0/0 next-hop 192.168.1.1
