Ch 6 Terms - Hardware, Switching & Routing

Question 1

EGP

Answer 1

A routing protocol that can span multiple autonomous networks.

Question 2

OSPF

Answer 2

A routing protocol that makes up for some of the limitations of RIP and can coexist with RIP on a network.

Question 3

IGP

Answer 3

A routing protocol, such as RIP, that can only route data within an autonomous (internal) network.

Question 4

Cut-through mode

Answer 4

A switch reads a frame’s header and decides where to forward the data before it receives the entire packet.

Question 5

STP

Answer 5

A switching protocol defined in IEEE 802.1D that prevents traffic loops.

Question 6

Link-State

Answer 6

A type of routing protocol that enables routers to share information, after which each router can independently map the network and determine the best path between itself and a packet’s destination node.

Question 7

Distance-Vector

Answer 7

A type of routing protocol. Some, like RIP, only factor in the number of hops to the destination, while others take into account latency and other network traffic characteristics.

Question 8

Dynamic Routing

Answer 8

Automatically calculates the best path between two nodes and accumulates this information in a routing table.

Question 9

Border Router

Answer 9

Device that connects an autonomous LAN with an exterior network (example: connects a business to its ISP).

Question 10

Redirector

Answer 10

The component in a protocol suite responsible for intercepting requests from applications and determining whether the service is local or remote.

Question 11

RIP

Answer 11

The oldest routing protocol; uses distance-vector (hop count) as its routing metric. Uses Port 520.

Question 12

Bus

Answer 12

The type of circuit used by a computer’s motherboard to transmit data to components.

Question 13

BID

Answer 13

A bridge’s identification consisting of a 2-byte priority field and the bridge’s MAC address.

Question 14

EIGRP

Answer 14

A Cisco routing protocol that supports multiple protocols and limits unnecessary network traffic between routers.

Question 15

Gateway

Answer 15

A combination of networking hardware and software that connects two dissimilar kinds of networks. Provides session management and data translation.

Question 16

Switch

Answer 16

A connectivity device that logically subdivides a network into smaller, individual collision domains. It can interpret MAC address information to determine whether to discard or forward packets it receives.

Question 17

Bridge

Answer 17

A connectivity device that reads header information to forward packets according to their MAC addresses. It contains one input and one output port and separate network segments.

Question 18

Transceiver

Answer 18

A device that both transmits and receives and shares common circuitry or a single housing. When no circuitry is common between transmit and receive functions, the device is a transmitter-receiver.

Question 19

Firewall

Answer 19

A device that selectively filters or blocks traffic between networks.

Question 20

BGP

Answer 20

A distance-vector routing protocol capable of considering many factors in its routing metrics; mostly used on Internet backbones.

Question 21

IS-IS

Answer 21

A link-state routing protocol that uses a best-path algorithm for interior routers only.

Question 22

Hub

Answer 22

A network connectivity device. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Question 23

Repeater

Answer 23

A network device used to regenerate or replicate a signal. It is used in transmission systems to regenerate analog or digital signals distorted by transmission loss. The analog variety can only amplify the signal while the digital variety can reconstruct a signal to near its original quality.

Question 24

VLAN

Answer 24

A network within a network that is logically defined by grouping its devices’ switch ports in the same broadcast domain.
