CompTIA Network+ (N10-008) — Question 227

Which of the following layers of the OSI model has new protocols activated when a user moves from a wireless to a wired connection?

Answer options

• A. Data link
• B. Network
• C. Transport
• D. Session

Correct answer: A

Explanation

The Data Link layer is responsible for establishing and controlling the connection between devices on a local network. When switching from a wireless to a wired connection, the protocols at this layer need to be re-established to accommodate the different types of connections, while the other layers like Network, Transport, and Session do not directly handle the transition between these physical media.
