Palo Alto Networks Network Security Analyst — Question 8

A financial company is deploying NGFWs with the Advanced SD-WAN subscription to improve uptime and bandwidth across thousands of ATMs. The company requires that traffic flows to the internal application needed by the ATMs always use the path with the lowest latency and packet loss.
Which unique SD-WAN rule parameters meet this criteria?

Answer options

• A. Application/Service: "Internal Application for ATMs" → Path Selection: "Best Available Path" in Traffic Distribution Profile.
• B. Application/Service: "Internal Application for ATMs" & "Management" in Path Quality Profile → Path Selection "Any."
• C. Application/Service: "Internal Application for ATMs" → Path Selection "Weighted Distribution" in Traffic Distribution Profile.
• D. Application/Service: "Internal Application for ATMs" & "ATM Path(Custom)" in Path Quality Profile → Path Selection "Any."

Correct answer: A

Explanation

The correct answer, A, ensures that the traffic for the internal application uses the 'Best Available Path', which prioritizes the path with the lowest latency and packet loss. Options B and D do not specify a path selection that guarantees optimal performance, while option C uses 'Weighted Distribution,' which does not necessarily select the path with the best latency and packet loss.
