DTransport

Show Suggested Answer

Suggested Answer: C

The Session layer (Layer 5 of the OSI model) is responsible for establishing, maintaining, and terminating communication sessions between network applications. It ensures that data exchanges remain synchronized and structured.

Data link layer handles error detection and frame transmission.

Physical layer deals with hardware-level transmission.

Transport layer ensures reliable data delivery but does not manage sessions.

I’m confused because I remember the Data link layer handles node-to-node communication. Could it be that one?

I practiced a similar question last week, and I think the Transport layer is more about data transfer, so I’m leaning towards C) Session too.

I think the answer might be C) Session, but I'm not entirely sure. I remember it has to do with managing connections.
