Palo Alto Networks NGFW Engineer — Question 10

How does a Palo Alto Networks firewall choose the best route when it receives routes for the same destination from different routing protocols?

Answer options

• A. The route that was received first will be entered into the forwarding table, and all subsequent routes will be rejected.
• B. It will attempt to load balance the traffic across all routes.
• C. It compares the administrative distance and chooses the one with the highest value.
• D. It compares the administrative distance and chooses the one with the lowest value.

Correct answer: D

Explanation

The correct answer is D because a Palo Alto Networks firewall utilizes the administrative distance metric to determine the best route, favoring the one with the lowest value, which indicates a more preferred route. Option A is incorrect as it does not consider administrative distance, B is misleading since load balancing is not the primary decision factor, and C is wrong because the firewall selects the route with the lowest, not highest, administrative distance.
