patch


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

source MAC
source IP
*destination MAC
destination IP
network IP address


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

STP
*UTP

9 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


10 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.


11 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


12 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


13 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.


14 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


15 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


16 What is characteristic of the operation of a hub?

selectively drops packets that represent potential security risks
* forwards a frame out all interfaces except the inbound interface
based on IP address, dynamically learns the interfaces to which all devices are attached
upon power on, queries the devices on all interface to learn the MAC addresses of the attached devices
transmits a frame to the specific interface to which the device with the MAC destination address is attached


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

physical
application
network
transport
*data link
session

routers
bridges
switches
*repeaters
