Question #1

You are deploying threat remediation to endpoints connected through third-party devices.

In this scenario, which three statements are correct? (Choose three.)

A . All third-party switches must support AAA/RADIUS and Dynamic Authorization Extensions to the RADIUS protocol.
B . The connector uses an API to gather endpoint MAC address information from the RADIUS server.
C . All third-party switches in the specified network are automatically mapped and registered with the RADIUS server.
D . The connector queries the RADIUS server for the infected host endpoint details and initiates a change of authorization (CoA) for the infected host.
E . The RADIUS server sends Status-Server messages to update infected host information to the connector.

Correct Answer: ACD
ACD

Explanation:

To enable Advanced Policy-Based Routing (APBR) on SRX Series devices, three key components are necessary: filter-based forwarding, routing instances, and APBR profiles. Filter-based forwarding is utilized to direct specific traffic flows to a routing instance based on criteria set by a policy. Routing instances allow the traffic to be managed independently of the main routing table, and APBR profiles define how and when traffic should be forwarded. These elements ensure that APBR is flexible and tailored to the network’s requirements. Refer to Juniper’s APBR Documentation for more details.

Advanced policy-based routing (APBR) in Juniper’s SRX devices allows the selection of different paths for traffic based on policies, rather than relying purely on routing tables.

To enable APBR, the following core components are required:

Filter-based Forwarding (Answer A): Filter-based forwarding (FBF) is a technique used to forward traffic based on policies rather than the default routing table. It is essential for enabling APBR, as it helps match traffic based on filters and directs it to specific routes.

Configuration Example:

bash

set firewall family inet filter FBF match-term source-address 192.168.1.0/24 set firewall family inet filter FBF then routing-instance custom-routing-instance

Routing Instance (Answer C): A routing instance is required to define the separate routing table used by APBR. You can create multiple routing instances and assign traffic to these instances based on policies. The traffic will then use the routes defined within the specific routing instance.

Configuration Example:

bash

set routing-instances custom-routing-instance instance-type forwarding

set routing-instances custom-routing-instance routing-options static route 0.0.0.0/0 next-hop 10.10.10.1

APBR Profile (Answer D): The APBR profile defines the rules and policies for advanced policy-based routing. It allows you to set up conditions such as traffic type, source/destination address, and port, and then assign actions such as redirecting traffic to specific routing instances.

Configuration Example:

bash

set security forwarding-options advanced-policy-based-routing profile apbr-profile match application http

set security forwarding-options advanced-policy-based-routing profile apbr-profile then routing-instance custom-routing-instance

Other Components:

Routing Options (Answer B) are not a core component of APBR, as routing options define the general behavior of the routing table and protocols. However, APBR works by overriding these default routing behaviors using policies.

Policies (Answer E) are crucial in many network configurations but are not a core component of enabling APBR. APBR specifically relies on profiles rather than standard security policies. Juniper Security

Reference: Advanced Policy-Based Routing (APBR): Juniper’s APBR is a powerful tool that allows routing based on specific traffic characteristics rather than relying on static routing tables. APBR ensures that specific types of traffic can take alternate paths based on business or network needs.

Reference: Juniper Networks APBR Documentation.
