CompTIA Network+ (N10-007) — Question 79

A firewall administrator is implementing a rule that directs HTTP traffic to an internal server listening on a non-standard socket. Which of the following types of rules is the administrator implementing?

Answer options

• A. NAT
• B. PAT
• C. STP
• D. SNAT
• E. ARP

Correct answer: B

Explanation

The correct answer is PAT (Port Address Translation) because it allows multiple devices on a local network to be mapped to a single public IP address but with different ports. NAT (Option A) translates private IP addresses to a public IP address, but does not specifically handle port translation like PAT. The other options (C, D, E) are not relevant to the context of redirecting HTTP traffic to a specific internal server port.
