Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 164

ICMP packets do not contain port numbers. Therefore, NAPT cannot be used.

Answer options

• A. TRUE
• B. FALSE

Correct answer: A

Explanation

The statement is correct because ICMP operates at the network layer and does not use port numbers, which are required for NAPT (Network Address Port Translation) to function properly. As a result, NAPT cannot be applied to ICMP traffic, making the answer TRUE.
