Systems Security Certified Practitioner (SSCP) — Question 28

In which layer of the OSI Model are connection-oriented protocols located in the TCP/IP suite of protocols?

Answer options

• A. Transport layer
• B. Application layer
• C. Physical layer
• D. Network layer

Correct answer: A

Explanation

The correct answer is A, as connection-oriented protocols, such as TCP, operate at the Transport layer of the OSI Model. The other options are incorrect because the Application layer deals with high-level protocols, the Physical layer is concerned with the transmission of raw bit streams, and the Network layer handles routing and addressing of packets.
