Module 3.1

Question 1

Layer 1 device that regenerates and retransmits signals to overcome media distance limitations.

Answer 1

repeater

Question 2

These powered converters change light signals from SMF cabling into electrical signals carried over a copper wire Ethernet network (and vice versa).

Answer 2

Single mode fiber to twisted pair-

Question 3

A different media converter model is required to convert the light signals carried over MMF media

Answer 3

Multimode fiber to twisted pair

Question 4

These passive (unpowered) devices convert between the two fiber cabling types.

Answer 4

Single mode to multimode fiber

Question 5

Most Ethernet networks are implemented so that each end system node is wired to a _______________ system

Answer 5

central intermediate

Question 6

Layer 1 (Physical) network device used to implement a star network topology on legacy Ethernet networks, working as a multiport repeater

Answer 6

hub

Question 7

System that distinguishes transmit and receive pins on different interface types. The interface on an end system is MDI while that on an intermediate system is MDI-X.

Answer 7

medium dependent interface (MDI)×

Question 8

the interface on the hub is referred to as MDI crossover (MDI-X). This means that the ____________ wires on the host connect to receive (Rx) wires on the hub.

Answer 8

transmit (Tx)

Question 9

Intermediate system that isolates collision domains to separate segments while joining segments within the same broadcast domain.

Answer 9

Bridge

Question 10

Network segment in which all nodes receive the same broadcast frames at layer 2.

Answer 10

Broadcast Domain

Question 11

Intermediate system used to establish contention-free network segments at layer 2 (Data Link).

Answer 11

switch

Question 12

Function of an Ethernet switch whereby collision domains are reduced to the scope of a single port only.

Answer 12

micro segmentation

Question 13

In effect, the __________ establishes a point-to-point link between any two network nodes

Answer 13

switch

Question 14

The transceiver component responsible for physically connecting the node to the transmission medium is implemented in a __________________________

Answer 14

network interface card/controller (NIC).

Question 15

Most ___________________ designed for use with copper cabling are capable of 10/100/1000 operation, meaning that they support Gigabit Ethernet, Fast Ethernet, and 10BASE-T

Answer 15

Ethernet adapters
