Palo Alto Networks SD-WAN Engineer — Question 1

A site has two internet circuits: Circuit A with 500 Mbps capacity and Circuit B with 100 Mbps capacity.
Which path policy configuration will ensure traffic is automatically shifted from a saturated circuit to the circuit with available bandwidth?

Answer options

• A. Circuit A as an active, Circuit B as a backup
• B. Circuit B as an active, Circuit A as a backup
• C. Both circuits under active path
• D. Circuit B as an L3 failure path

Correct answer: C

Explanation

The correct answer is C because having both circuits configured under active path allows for automatic load balancing and traffic shifting based on available bandwidth. Options A and B only allow for one circuit to be used at a time, which wouldn't effectively redirect traffic during saturation. Option D does not provide a mechanism for balancing traffic under normal conditions.
