3 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

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

• 1
• 2*
• 4
• 7
• 8

5 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.
• tation 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.

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 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

8 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

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

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

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

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

15 Users with systems that are attached to a hub are complaining about poor response time. What device could replace the hub and provide immediate response time improvement?

• router
