Question

What layer does Protocol TFTP belong to in the DOD model? and in the OSI Model? Port#? What does it stand for and what does it do?

A) DOD Model: Application; OSI Model: Transport; Port #: 69; TFTP stands for Trivial File Transfer Protocol and is used for simple file transfers with minimal security.
B) DOD Model: Network; OSI Model: Application; Port #: 22; TFTP stands for Trivial File Transfer Protocol and is used for web browsing.
C) DOD Model: Application; OSI Model: Application; Port #: 23; TFTP stands for Trivial File Transfer Protocol and is used for remote terminal connections.
D) DOD Model: Transport; OSI Model: Transport; Port #: 20; TFTP stands for Trivial File Transfer Protocol and is used for secure file transfers.

Answer 1

TFTP, or Trivial File Transfer Protocol, resides at the Application layer of both the DoD and OSI models and uses UDP port 69 for file transfers.

Step-by-step explanation:

Protocol TFTP belongs to the Application layer in both the Department of Defense (DoD model) and the Open Systems Interconnection (OSI model). As for the protocol details, TFTP stands for Trivial File Transfer Protocol and is known for its simplicity in transferring files. It operates on UDP port number 69. Unlike FTP, TFTP does not provide authentication or guarantee security during the file transfer process, making it suitable for environments where security is not a concern and simplicity is prioritized.
