Lesson 5: Network Protocols

Question 1

The process of running an algorithm and comparing it to the stored result.

Answer 1

Checksum

Question 2

The time it takes a router to send an update of its routing table to all routers directly connected to it.

Answer 2

Convergence

Question 3

An attempt by hackers to make a target IP address unavailable to its intended users by launching continuous ping requests from numerous computers so frequently that the target computer’s network capacity is overloaded and brought down.

Answer 3

Denial of Service (DoS) Attack

Question 4

The simplest type of routing protocol that simply informs its neighbors of it’s routing table.

Answer 4

Distance Vector Routing Protocol

Question 5

A type of routing that occurs when a protocol dynamically creates its own routing tables and keeps them updated.

Answer 5

Dynamic Routing

Question 6

Routing protocols which use the distance vector metrics-based method of determining best routes,while using the link state method of updating the other routers in the network

Answer 6

Hybrid Routing Protocol

Question 7

A major protocol type used by routers to construct their routing tables. Each router constructs a map of all routers on a network and updates those routers with it’s entire network map.

Answer 7

Link State Routing Protocol

Question 8

Measurements used by a routing protocol to determine the best routes available to it.

Answer 8

Metrics

Question 9

The IP or other protocol address of the next stop along the path to the desired destination.

Answer 9

Next Hop

Question 10

A program used to determine whether a specific IP address can be reached on the network.

Answer 10

Ping

Question 11

A unique address inside the computer that is associated with a specific protocol, service, or application.

Answer 11

Port Address

Question 12

A predefined and widely accepted set of rules used to describe exactly how a specific task is to work in a network environment.

Answer 12

Protocol

Question 13

All the protocols from a protocol suite currently used to carry out specific functions of network communications within the computer.

Answer 13

Protocol Stack

Question 14

A group of networking protocols designed to work together to carry out all functions needed for data to be communicated across a network.

Answer 14

Protocol Suite

Question 15

Documents by which all networking standards and protocols are defined.

Answer 15

Request for Comment (RFC)

Question 16

A type of protocol that routers and other network devices can use over a network.

Answer 16

Routed Protocol

Question 17

A type of protocol used by routers to compile routing tables that routed protocols move around the network.

Answer 17

Routing Protocol

Question 18

Small databases that routers and other networked devices refer to, to determine which route to rake to get to a specific network location.

Answer 18

Routing Table

Question 19

Routing that occurs when routing tables are manually changed or updated as new routes are needed on a network or old routes change.

Answer 19

Static Routing

Question 20

When the routers on a network remain in a converged state, it is said that they are operating in a _____ _____.

Answer 20

Steady State

Question 21

A code number assigned to network user sessions or applications when using the TCP protocol to identify the transaction.

Answer 21

TCP Port

Question 22

The most commonly used group of protocols designed to work together to carry out all functions needed for data to be communicated across a network.

Answer 22

TCP/IP Protocol Suite

Question 23

A terminal emulation program that provides bidirectional interactive command line access to either a remote or local host.

Answer 23

TELNET (TEerminaL NETwork)

Question 24

Microsoft Windows version of traceroute.

Answer 24

Tracert

Question 25

A connectionless counterpart of TCP port.

Answer 25

UDP (User Datagram Protocol) port
