Question 210
A network specialist investigates this evidence: Hundreds of private office clients need outbound access through one public IPv4 address. Which underlying condition BEST explains the observed failure or requirement?
Explanation
Correct Answer
Address-only one-to-one NAT cannot distinguish all concurrent shared flows. PAT shares one public IP by translating source ports and recording flows.
Incorrect Answers
The internet-facing service lacks a deterministic inbound translation. That does not establish the intended translated source or destination path.
Stateful NAT requires return traffic to match its stored flow mapping. That does not establish the intended translated source or destination path.
Internet external routing requires interdomain policy exchange. That does not establish the intended translated source or destination path.
