Supporting Cisco Routing and Switching Network Devices (RSTECH, legacy) — Question 7

Which IOS layer does a server use to keep track of which application communications in which conversation?

Answer options

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

Correct answer: A

Explanation

The correct answer is A, Transport, as this layer is responsible for managing end-to-end communication and ensuring that data is delivered accurately and in sequence between applications. The Network layer (B) focuses on routing packets between devices, while the Session layer (C) is responsible for establishing and maintaining sessions, but it does not track application communications. The Application layer (D) provides network services directly to applications but does not manage the conversation itself.
