length of the network cable

*number of users on the network

4 Which protocols are commonly part of the application layer of the TCP/IP model? (Choose three.)

*FTP

*DNS

UDP

TCP

*HTTP

5 Which of the following are data link layer encapsulation details? (Choose two.)

*Packets are put into frames.

Data is packaged into a packet.

Data is segmented into segments.

Data is converted for Internet travel.

*An address is added to identify the directly connected device.

6 Which device is used to connect LANs that are geographically separated?

hub

bridge

*router

repeater

7 Which of the following is the Layer 4 PDU?

bit

frame

packet

*segment

8 What is important to remember about the data link layer of the OSI model when considering Peer to Peer communication? (Choose three.)

It links data to the transport layer.

It encapsulates frames into packets.

*It provides a service to the network layer.

*It encapsulates the network layer information into a frame.

*Its header contains a physical address which is required to complete the data link functions.

It encodes the data link frame into a pattern of 1s and 0s (bits) for transmission on the medium.

9 Which of the following is true regarding network bandwidth?

Bandwidth is free.

*Bandwidth has capacity limits.

Bandwidth never increases.

Bandwidth is not a key factor in analyzing network performance.

10 Which of the following is the official name for the address assigned to each network interface card (NIC) by its manufacturer?

NIC address

*MAC address

IP address

Source Address

11 Which physical network topology uses a single backbone cable and connects all hosts directly to this cable?

ring

star

*bus

mesh

12 Which OSI and TCP/IP layer appears in both models yet has different functions in each?

transport

session

*application

Internet

physical

13 Which of the following topologies are considered logical topologies? (Choose two.)

bus

*token-passing

star

mesh

*broadcast

hierarchical

14 During the data encapsulation process, how is the data broken down by the transport layer?

packets

*segments

data bits

frames

15 Which of the following describe a LAN? (Choose two.)

*operates within a limited geographical area

provides dial-up connectivity

uses serial interfaces to allow operation at lower speeds

*connects physically adjacent devices

ensures single access to specialty hosts

16 Which of the following are considered valid types of VPNs? (Choose three.)

internal

* intranet

external

*extranet

local

*access

17 Which of the following physical topologies connects all cables to a central point of concentration?

ring

*star

mesh

bus

18 Refer to the figure. What is the maximum possible throughput obtained end to end on this network when the user on Lab A communicates with the user on LAB D?

The maximum possible throughput is based on the largest connection, the T3.

*The maximum possible throughput is based on the smallest connection, the T1.

There is not enough data to determine the maximum possible throughput.

The maximum possible throughput is the T1 plus T3 speed divided by 2.

application

internet

* transport

network

22 From the following list, choose the data packaging type that is created at the data link layer during the data encapsulation process.

packets

segments

data bits

* frames

23 Refer to the following list. Choose the correct order of data encapsulation when a device sends information.

segments

bits

packets

data

frames
