NEW QUESTION # 40
Which two elements are necessary to configure a rule under an APBR profile? (Choose Two)

A. match condition
B. then action
C. instance type
D. RIB group

Answer: A,B

Explanation:
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.

NEW QUESTION # 41
You are asked to set up advanced policy-based routing.
Which type of routing instance is designed to support this scenario?

A. forwarding
B. virtual switch
C. virtual router

Answer: A

Explanation:
Comprehensive Detailed Step-by-Step Explanation with All Juniper Security References Understanding Advanced Policy-Based Routing (APBR):
* APBR: Allows routing decisions based on application-level information and policies.
* Objective: Direct specific application traffic through different paths based on policies.
Routing Instances in Junos OS:
* Forwarding Instance:
* Used for features like filter-based forwarding (FBF) and APBR.
* Provides a separate forwarding table but shares the global routing table.
* Supports APBR.
* Virtual Router:
* Provides a separate routing table and forwarding table.
* Used for logical separation of routing domains.
* Does not support APBR directly.
* Virtual Switch:
* Operates at Layer 2.
* Used for VLAN separation and Layer 2 switching.
* Not applicable to routing or APBR.
* Non-Forwarding Instance:
* Used for management purposes.
* Does not forward transit traffic.
* Not suitable for APBR.
* Option A: forwarding
* Correct.
* A forwarding routing instance is specifically designed to support advanced policy-based routing.
* It allows the SRX device to direct traffic based on policies to different forwarding instances.

NEW QUESTION # 42
Exhibit

You configure Source NAT using a pool of addresses that are in the same subnet range as the external ge-0/0/0 interface on your vSRX device. Traffic that is exiting the internal network can reach external destinations, but the return traffic is being dropped by the service provider router.
Referring to the exhibit, what must be enabled on the vSRX device to solve this problem?

A. STUN
B. Persistent NAT
C. DNS Doctoring
D. Proxy ARP

Answer: C

NEW QUESTION # 43
You are asked to see if your persistent NAT binding table is exhausted.
Which show command would you use to accomplish this task?

A. show security nat source summary
B. show security nat source persistent-nat-table summary
C. show security nat source persistent-nat-table all
D. show security nat source pool all

Answer: C

Explanation:
The command show security nat source persistent-nat-table all provides a comprehensive view of all entries in the persistent NAT table, enabling administrators to monitor and manage resource exhaustion. Refer to Juniper NAT Monitoring Guide for more.
In Junos OS, whenpersistent NATis configured, a binding table is created to keep track of NAT sessions and ensure that specific hosts are allowed to initiate sessions back to internal hosts. To check if the persistent NAT binding table is full or exhausted, the correct command must display theentire table.
* Correct Command (D):
* The commandshow security nat source persistent-nat-table allwill display the entire persistent NAT binding table. This allows you to check whether the table is exhausted or if there is space available for new persistent NAT sessions.
* Incorrect Options:
* Option A: The command show security nat source persistent-nat-table summary provides a summary view but does not give detailed insights into whether the table is exhausted.
* Option BandOption C: These commands deal with general NAT source summaries or pools, which are not related specifically to persistent NAT bindings.
Juniper References:
* Juniper Persistent NAT Documentation: Describes the persistent NAT binding table and the commands used to monitor its status.
