Which form of NAT uses port addresses to distinguish between translated sessions? 1 pointstatic NATpolicy NATdynamic PATdynamic NAT

Breakdown of the Problem

1. Understand the different types of NAT (Network Address Translation).
2. Identify which NAT form uses port addresses for session distinction.

Relevant Concepts

• Static NAT: Maps a private IP address to a public IP address permanently.
• Policy NAT: Allows for more complex rules based on the traffic flow.
• Dynamic NAT: Maps private IP addresses to a pool of public IP addresses.
• Dynamic PAT (Port Address Translation): Also known as NAT overload, it allows multiple devices on a local network to be mapped to a single public IP address but differentiates them by using different port numbers.

Analysis and Detail

• Static NAT does not use ports; it is a straightforward mapping.
• Policy NAT is rule-based but doesn't specifically refer to port addressing.
• Dynamic NAT uses a pool for addressing but not ports to distinguish sessions.
• Dynamic PAT distinguishes sessions based on port numbers, allowing multiple sessions to use the same public IP address.

Verify and Summarize

Dynamic PAT is the correct answer as it specifically utilizes port numbers to differentiate between multiple sessions that share the same public IP address.

Final Answer

Dynamic PAT.
