Certified Network Defender (CND) — Question 173

Which of the following layers of the OSI model provides interhost communication?

Answer options

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

Correct answer: D

Explanation

The correct answer is D, as the Session layer is responsible for establishing, managing, and terminating sessions between applications on different hosts. The other layers, while important for communication, do not specifically handle interhost sessions; for instance, the Transport layer focuses on data transfer reliability, the Network layer manages routing, and the Application layer deals with software interfaces.
