The layer 2 devices use the data link layer addresses.
Local delivery

They are defined in the OSI layer known as Data-Link.

The OSI model has seven layers whereby each layer has its function. The Data Link Layer is responsible for addressing data messages so that they reach their destination correctly.

The Hop-to-hop delivery is also called the node-to-node delivery and it is the delivery between two nodes connected to the same network by a link and this jib is carried out by the data link layer....
Data Link
the network layer --> check your question. ^^^^^^^^^^^^^^^^^^^^^^^^^^^ That is totally not the right answer, how about you actually read the book for the course. It is the data link layer that does encapsulation. I agree - its the Data Link Layer which encapsulates the Network layer...NOT the Network Layer.
Switches are on the second layer of the OSI model (Data Link); they do filtering based on host MAC addresses. You may also see a third layer switch; they not only provide all switching capabilities but some layer three routing capabilities too.
