1. Which of the following are benefits of peer-to-peer networks? (Choose three.)

centralized security

easy to create

very scalable

no centralized equipment required

centralized administrator not required

centralized control of assets

 

2. What is the most common type of cabling used in LANs?

STP

UTP

coax

fiber

 

3.

Which items in the exhibit are DTE devices?

A and B

B and C

C and D

A and D

A, B, C, and D

 

4. Which statement is accurate about a WAN link?

The link transmits data serially.

The link uses a maximum distance of 100 meters.

The link uses the same transmission rate as all other WAN links use.

The link uses the same standardized connector style that is used for all WAN technologies.

 

5. Which statement describes a typical use of Gigabit Ethernet?

to provide high-speed desktop connectivity for average users

to provide connectivity to low to medium volume applications

to provide medium volume connectivity to workgroup servers

to provide high-speed connectivity for backbones and cross connects

 

6. What is characteristic of how a hub operates?

A hub selectively drops packets that represent potential security risks.

A hub forwards data out all interfaces except the inbound interface.

A hub dynamically learns the interfaces to which all devices are attached.

At start up, a hub queries the devices on all interfaces in order to learn the MAC addresses of the attached devices.

A hub transmits a frame to a specific interface based on the destination MAC address.

 

7. At which layer of the OSI model does the MAC address of a NIC reside?

physical

application

network

transport

data link

session

 

8. What device is used to connect hosts to an Ethernet LAN and requires a straight-through UTP cable between the hosts and this device?

NIC

router

switch

server

 

9. In which situations would a crossover cable be used to connect devices in a network? (Choose two.)

switch to PC

switch to hub

switch to router

switch to server

switch to switch

 

10. Which of the following are benefits of a wireless network? (Choose two.)

higher data speeds

better security

mobility

less expensive NIC cards

no need to run cables to hosts

 

11.

The ends of a UTP cable are shown in the exhibit. Which cable configuration is shown?

console

crossover

rollover

reversed-pair

split-pair

straight-through

 

12. Which two devices are considered OSI Layer 1 devices? (Choose two.)

hubs

routers

bridges

switches

repeaters

 

13.

Refer to the exhibit. How many collision domains exist in the network?

1

2

4

7

8

 

14.

Which function is a unique responsibility of the DCE devices shown in the exhibit?

transmission of data

reception of data

clocking for the synchronous link

noise cancellation in transmitted data

 

15.

Refer to the exhibit. A technician measured the lengths of the CAT 5e structured cable runs in the exhibit. How should the technician evaluate the cabling shown in the diagram to the network administrator?

All cabling to work areas are within specifications.

Station A and B may experience intermittent problems because the length exceeds the recommended standard.

Station B may experience intermittent problems because the length exceeds the recommended standard.

Station C may experience intermittent network connectivity because the length is less than the recommended standard.

Station A and B will have intermittent problems because the length exceeds the recommended standard.

Station C will not have network connectivity because the length is less than the recommended standard.

 

16. What type of cable would be used to make the connection between the console port of a router and a workstation?

crossover

rollover

straight-through

patch

 

17.

The ends of a UTP cable are shown in the exhibit. Which cable configuration is shown?

crossover

rollover

reversed-pair

straight-through

split-pair

console

 

18. Which address does a bridge use to make filtering and switching decisions?

source MAC

source IP

destination MAC

destination IP

network IP address

 

19.

Refer to the exhibit. What is the appropriate cable to use at each of the numbered network connections?

1-crossover; 2-straight-through; 3-crossover; 4-straight-through

1-straight-through; 2-crossover; 3-straight-through; 4-straight-through

1-straight-through; 2-crossover; 3-crossover; 4-straight-through

1-rollover; 2-crossover; 3-straight-through; 4-straight-through

1-rollover; 2-straight-through; 3-straight-through; 4-straight-through
