Answers to Questions 16-20

16. An AUI connector can be found on which of the following?

A. NIC

B. External Transceiver

C. Network Hub

D. Fast Ethernet NIC

E. Token Ring NIC

Explanation: AUI (Attachment Unit Interface) dictates what connector type will be used to attach a cable to a NIC. Transceivers and hubs also utilize this standard.

& Domain 1.4: Recognize falling media connectors and/or describe their uses: RJ-11, RJ-45, AUI, BNC, ST, and SC.


 

17. Which cable type is limited to 100 Mbps and supports a maximum distance of 100 meters?

A. 10Base2

B. 10Base5

C. 100BaseF

D. 100BaseT

E. 100BaseFX

Explanation: Cat 5 cabling is 100BaseT and has the limits of 100Mbps, and 100 meters from end to end without boosting the signal with a repeater.

& Domain 1.3: Specify the characteristics with (e.g., speed, length, topology, cable type, etc.) of the following: 802.3 (Ethernet) standards, 10 Base-T, 100 Base-TX, 10 Base2, 10Base5, 100 Base-FX, Gigabit Ethernet.


 

18. You have just been hired at a new company, and the network is not working. You review the existing network, and find the overall 10baseT cable length is over 100 meters.

Required result:

  • Make the network operational

Optional desired result:

  • Improve performance

  • Keep costs down

Proposed solution:

  • Install 100BaseFX NICs on all PCs, and run SNMP on all servers.

 

A. Meets neither the required nor the desired objectives

B. Meets the required but not the desired objective

C. Meets desired objective but not the required objective

D. Meets both the required and the desired objectives

E. Meets the desired and one of the optional objectives

Explanation: Replacing the NICs with fast Ethernet cards will not resolve the cabling problem, and 100BaseFX NICs are for fiber optic cabling, which may be overkill for this situation.

An immediate fix would be to install a repeater between each 100-meter length. Since the type of cabling is not indicated, you can not consider changing the cabling in their system. The first optional objective could be achieved by installing Fast Ethernet NICs. You also would need compliant cabling, switches, and other hardware to ensure fast Ethernet capabilities.

& Domain 1.3: Specify the characteristics with (e.g., speed, plant, topology, cable type, etc.) of the following: 802.3 (Ethernet) standards, 10 Base-T, 100 Base-TX, 10 Base2, 10Base5, 100 Base-FX, Gigabit Ethernet.


 

19. 802.11b has a maximum bandwidth of

A. 5.5Mpbs

B. 2Mbps

C. 1Mpbs

D. 11Mpbs

E. No choice is correct

Explanation: 11Mpbs is the maximum; the other choices are "fallback" bandwidth rates.

& Domain 1.2: Specify the main features of 802.2 (LLC), 802.3 (Ethernet), 802.5 (token ring), 802.11 (wireless) and FDDI networking technologies, including: Speed, Access, Method, Topology, Media.


 

20. ___________ cabling would be used to connect to a server one kilometer away or less without having to use a repeater.

Fiber Optic

Explanation: Fiber optic cabling can transmit data across distances of up to one kilometer, a much larger distance than the limits placed on most UTP type cablings, which are upwards of 100 meters.

& Domain 1.3: Specify the characteristics with (e.g., speed, length, topology, cable type, etc.) of the following: 802.3 (Ethernet) standards, 10 Base-T, 100 Base-TX, 10 Base2, 10Base5, 100 Base-FX, Gigabit Ethernet.
