29. C4A
This intelligent device makes decisions about which outgoing port to send a frame based on destination MAC address

30. C4Q
What is a switch?

31. They also interconnect LANs.

42. What is the Transport Layer, Layer 4?
D5Q
What is the Transport Layer, Layer 4?

43. E1A
Layers that only communicate with one other layer when sending or receiving a message besides its peer on the destination node.

44. What are the Application and Physical Layers?
E1Q
What are the Application and Physical Layers?
The Application Layer communicates with the Presentation Layer below it and with the computer/operating system above it as well as the Application Layer on the destination node.
Likewise, the Physical Layer only communicates with the Data Link Layer (actually, the MAC sublayer) when receiving a message as well as communicating with its peer Physical Layer on the Source Node.
