This question requires that you evaluate the underlined text to determine if it is correct.
An ICMP ping message is sent at the application layer of the OSI model.
Review the underlined text. If it makes the statement correct, select "No change is needed." If the statement is incorrect, select the answer choice that makes the statement correct.

Answer options

• A. network
• B. transport
• C. data-link
• D. No change is needed

Correct answer: A

The correct answer is A, as ICMP operates at the network layer of the OSI model, not the application layer. The other options (B and C) refer to different layers that are also incorrect, and D is incorrect because the statement is not accurate as originally stated.
