Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 401

If an administrator wants to apply QoS to traffic based on source, what must be specified in a QoS policy rule?

Answer options

• A. Post-NAT destination address
• B. Pre-NAT destination address
• C. Pre-NAT source address
• D. Post-NAT source address

Correct answer: C

Explanation

The correct answer is C because applying QoS based on the source requires the identification of the source address before NAT is applied. Options A and B refer to destination addresses, which are irrelevant for source-based QoS, while option D specifies the source address post-NAT, which does not accurately represent the source before translation.
