d. TCP/IP mapping
3. Think generically about the idea of a networking standard, ignoring any particular standard or ...view middle of the document...
c. The physical layer sits just below the data link layer.
d. The network layer sits in the middle of the five layers.
6. The TCP/IP model refers to standards other than those the IETF defines in RFCs. Which of these
standards groups is typically the source of external LAN standards? (Choose two answers.)
7. Which of the following is not a typical reason for a group of ten companies to start a vendor group, for the purpose of pushing a new networking technology?
a. To get products that use this technology to market more quickly
b. To increase overall acceptance of the technology by having more vendors that support the technology
c. To improve the chances that the technology will be standardized
d. To keep intellectual property rights to the technology inside the company
8. The TCP/IP and OSI models have some obvious differences, like the number of layers. Think about the more commonly used version of the TCP/IP model discussed in this chapter, and then think about how to talk about TCP/IP using OSI terms. Which of the following is a correctly phrased statement for how to use OSI terminology?
a. HTTP is a Layer 5 protocol.
b. IP is a network layer protocol.
c. TCP is a Layer 2 protocol.
d. Leased lines are Layer 7 standards.
9. Historically, which of the following models were the earliest models used in corporate networks?
a. Vendor models
10. Which of the following statements is true when comparing the OSI and the TCP/IP model as defined in RFC 1122?
a. Two layer names match.
b. The lower four layers of TCP/IP define the same kinds of functions as the matching layer numbers from OSI.
c. The TCP/IP five-layer model is old and has been replaced by the seven-layer OSI model.
d. The TCP/IP application layer defines functions that match closely to only two OSI layers (application and presentation).
11. A network engineer connects two PCs (PC1 and PC2) using Ethernet NICs and an Ethernet cable that has copper wires inside. The two PCs communicate successfully. Which of the following happens when PC1 sends bits to PC2?
a. PC1’s NIC uses its decoder.
b. The PCs use one wire to create a circuit to send data from PC1 to PC2.
c. The PCs use two wires to create a circuit to send data from PC1 to PC2.
d. PC1 converts the bits to sound waves, and the NIC uses an A/D converter to send the data over the cable.
12. A TCP/IP network includes an Ethernet LAN with 10 PCs uses a LAN switch. PC1 sends data intended for an app running on PC2. Which of the following mechanisms does Ethernet define so that PC2 receives and processes the data?
a. The Ethernet header lists PC2’s MAC address so that PC2 will realize that the data is meant for PC2.
b. Ethernet defines MAC addresses, but when used in a TCP/IP network, it does not use the addresses, instead relying...
