Answer #1

C is correct. Packet is the PDU at the Network layer.

A, B, D, and E are incorrect. A is incorrect because the data is the PDU for the top three layers. B is incorrect because the Layer 4 PDU is called a segment. D is incorrect because the frame is the PDU for the Data Link layer. E is incorrect because the bit is the PDU for the Physical layer.

    A TCP segment consisting of 1500 bits of data and 160 bits of header is sent to the IP layer, which appends another 160 bits of header. This is then transmitted through two networks, each of which uses a 24-bit packet header. The destination network has a maximum packet size of 600 bits. How many bits, including headers, are delivered to the network layer protocol at the destination?

    A TCP segment consisting of 4,256 bits of data and 184 bits of TCP header is sent to the IP layer.  The IP layer uses 200 bits of header. The IP datagram is transmitted through two networks each of which uses a 20-bit header. The target network has a maximum packet size of 1,500 bits.    How many total bits, including headers, are delivered to the network layer protocol at the destination?
