Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 184

What is the function of a service route?

Answer options

• A. The service packets exit the firewall on the port assigned for the external service. The server sends its response to the configured source interface and source IP address.
• B. The service packets enter the firewall on the port assigned from the external service. The server sends its response to the configured destination interface and destination IP address.
• C. The service route is the method required to use the firewall's management plane to provide services to applications.
• D. Service routes provide access to external services, such as DNS servers, external authentication servers or Palo Alto Networks services like the Customer Support Portal.

Correct answer: A

Explanation

Option A is correct as it accurately describes how service packets exit the firewall and the response process. Option B is incorrect because it misstates the direction of the packets entering rather than exiting. Options C and D, while related to service routes, do not specifically answer the question about the function of a service route as directly as option A does.
