What are two services performed by the data link layer of the OSI model? (Choose two.)
- It encrypts data packets.
- It determines the path to forward packets.
- It accepts Layer 3 packets and encapsulates them into frames.
- It provides media access control and performs error detection.
- It monitors the Layer 2 communication by building a MAC address table.
Explanation:The data link layer is responsible for the exchange of frames between nodes over a physical network media. Specifically the data link layer performs two basic services: - It accepts Layer 3 packets and encapsulates them into frames.
- It provides media access control and performs error detection.
Path determination is a service provided at Layer 3. A Layer 2 switch builds a MAC address table as part of its operation, but path determination is not the service that is provided by the data link layer.
