Question 1

You cannot actually configure a router until you get to enable mode.

A) broadcast
B) unicast
C) multicast
D) anycast

Answer 2

A

Question 3

A(n) ____ occurs when two stations transmit more than 64 bytes of data frames before detecting a collision.

A) jabber
B) NIC error
C) late collision
D) alignment error

Answer 3

C

Question 4

____ switches read the entire frame, no matter how large, into their buffers before forwarding.

A) Fast-forward
B) Store-and-forward
C) fragment-free
D) cut-through

Question 5

____ represents an effort to provide more error-reducing benefits than cut-through switching, while keeping latency lower than does store-and-forward switching.

A) Fragment-free forwarding
B) Fast forwarding
C) Adaptive cut-through forwarding
D) Adaptive fast forwarding

Question 6

Routers, switches, bridges, and gateways segment networks and thus create separate collision domains.

Question 7

The main difference between a switch and a bridge is that the switch typically connects multiple stations individually, thereby segmenting a LAN into multiple collision domains.

Some switches can interconnect network interfaces of different speeds. These switches use ____ switching and, typically, a shared memory buffer.

A) symmetric
B) shared
C) virtual
D) asymmetric

Question 9

In ____ memory buffering, each port has a certain amount of memory that it can use to store frames.

A) exclusive
B) shared
C) port-based
D) content-addressable

Question 10

Switches that use ____ forwarding start sending a frame immediately after reading the destination MAC address into their buffers.

A) cut-through
B) store-and-forward
C) fragment-free
D) adaptive cut-through forwarding

Question 11

____ specifies that all collisions should be detected from anywhere in a network in less time than is required to place a 64-byte frame on the network.

A) Latency
B) Transmission time
C) Slot time
D) Bit time

Question 12

With ____ memory buffering, any port can store frames in the shared memory buffer.

A) content-addressable
B) shared
C) port-based
D) exclusive

Question 13

IEEE 802.3u specifies two types of repeaters: Class I and Class II. Class II repeaters have higher latency than Class I repeaters.

Question 14

A bridge maintains a ____ that maps the MAC addresses on each segment to the corresponding port on the bridge to which each segment is connected.

A) multicast table
B) map table
C) bandwidth table
D) bridging table

Question 15

A ____ operates at layer 3 of the OSI reference model. It interprets the Network layer protocol and makes forwarding decisions based on the layer 3 address.

A) switch
B) router
C) bridge
D) hub

Question 16

Fragment-free switches are also known as ____ switches.

A) fast forwarding
B) error sensing
C) cut-through
D) modified cut-through

Question 17

A(n) ____ is the physical area in which a packet collision might occur.

A) backoff domain
B) collision domain
C) IPG domain
D) jam domain

Question 18

____ refers to the amount of time required to transmit one data bit on a network.

A) Transmission time
B) Slot time
C) Latency
D) Bit time

Question 19

A ____ error indicates that bits of a frame were corrupted during transmission,

A) frame check sequence (FCS)
B) jabber
C) long frame
D) short frame

Question 20

When a segment has too much broadcast traffic, utilization increases and network performance in general benefits.

Question 21

Describe cut-through forwarding switching.

Question 22

What are the three defined implementations of Fast Ethernet?

Question 23

Generally speaking, a switch does not require an IP address, because switches operate mainly on Layer 2 (____ addresses).

A) IP
B) TCP
C) IPX
D) MAC

Question 24

In ____________________ communications, devices can send and receive signals simultaneously.

Question 25

____________________ is a network access method (or media access method) originated by the University of Hawaii, later adopted by Xerox Corporation, and standardized as IEEE 802.3 in the early 1980s.

Question 26

The amount of time it takes for a packet to be sent from one device to another is called the ____________________.

Question 27

What are some of the frame size errors that occur on Ethernet networks?

Question 28

How are collisions handled by CSMA/CD?

Question 29

What are the Gigabit Ethernet specifications and the governing IEEE standards?
