Answers to Questions 6-10 1 Answers to Questions 16-20

11. What are the characteristics of Token Ring?

A. Workstations are guaranteed a chance to transmit

B. Larger Frame size than Ethernet

C. Conforms to the IEEE 802.5 specification

D. Supports greater distances

E. Widely supported by most network vendors

Explanation: Token ring is considered the IBM network method, though now you can get adapters and other equipment from a variety of vendors. The list is still considerably smaller than Ethernet, and is not supported by most vendors. Token Ring is the 802.5 of the 802 family of specifications, and has a much larger frame or payload size than Ethernet. The distances supported are the same over twisted pair, however, and like Ethernet all stations on the network are guaranteed a chance to transmit. The difference is that Token Ring does not require retransmits due to collision.

& 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.

& 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.

12. External transceivers are used to convert:

A. Ethernet to Token Ring

B. Coax to Twisted Pair

C. Twisted Pair to Fiber

D. 802.2 to 802.3

E. Bridges to Routers

Explanation: External transceivers are devices to convert dissimilar physical connections, such as coax to twisted pair wire. However, they cannot convert protocol properties such as Ethernet to token ring.

& 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.

13. Which Ethernet adaptation(s) requires the use of 50-ohm terminators at the end of each segment?

A. 10Base-T

B. 10Base2

C. 10Base5

D. 10Base-F

E. SCSI

Explanation: On a bus network topology, only two terminators are used, one at each end. A network diagram that shows three terminators, for example, must be reworked so that it only has two.

& 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.

14. What does a patch cable connect to in a token ring network?

A. Two routers

B. Two or more hubs

C. Two MAUs

D. Two workstations

E. Two or more LANS

Explanation: A MAU (Media Access Unit) is the unit that makes a Token Ring network work.

& Domain 1.1: Recognize the following logical or physical network topologies given a schematic diagram or description: Star/ hierarchal, bus, mesh, ring, wireless.

& 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.

& 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.

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

15. What cabling type has a transmission speed of 100 Mbps and uses two twisted pairs of wires?

A. 10BaseT

B. 100BaseT

C. 10Base2

D. 10Base5

E. 10BaseFX

Explanation: Ethernet 10Mbps & 100Mbps uses Transmit/Ground and Receive/Ground. Gigabit Ethernet uses 4 pairs of cable.

& 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.
