Question:
What does a router do after de-encapsulating a received frame?

• determines the best path
• de-encapsulates the frame
• re-encapsulates the packet into a new frame
• forwards the new frame onto the network medium

Explanation: Routers are responsible for encapsulating a frame with a proper format for the physical network media the routers connect. At each hop along the path, a router does the following:
1. Accepts a frame from a medium
2. De-encapsulates the frame
3. Determines the best path to forward the packet
4. Re-encapsulates the packet into a new frame
5. Forwards the new frame appropriate to the medium of that segment of the physical network
