Implementing Cisco Secure Access Solutions (SISAS, legacy) — Question 56

Which command enables static PAT for TCP port 25?

Answer options

• A. nat (outside,inside) static 209.165.201.3 209.165.201.226 eq smtp
• B. nat static 209.165.201.3 eq smtp
• C. nat (inside,outside) static 209.165.201.3 service tcp smtp smtp
• D. static (inside,outside) 209.165.201.3 209.165.201.226 netmask 255.255.255.255

Correct answer: C

Explanation

The correct answer is C because it properly configures static PAT for TCP port 25 (SMTP) by specifying the inside and outside interfaces along with the service definition. Option A is incorrect as it uses the wrong interface order and does not specify the service keyword. Option B is missing the interface context, and option D is a static NAT configuration, not PAT.
