AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 205

Considering your knowledge of both the OSI and TCP/IP models `" select the following statement which you consider to NOT be true.

Answer options

• A. The TCP/IP Application layer maps to 2 of the OSI Layers
• B. The top layer in the OSI model is named the Application layer
• C. The TCP/IP Application layer maps to 3 of the OSI Layers
• D. The top layer in the TCP/IP model is named the Application layer

Correct answer: A

Explanation

The correct answer is A, as the TCP/IP Application layer actually corresponds to 3 OSI layers: Application, Presentation, and Session. Option B is true because the top layer of the OSI model is indeed the Application layer. Option C is false, as it misrepresents the mapping of the TCP/IP Application layer to OSI layers, while Option D correctly identifies the top layer of the TCP/IP model.
