Chapter 1: Differentiate between common network topologies

Question 1

What topology consists of two distinct and terminated ends with each of its computers connecting to one unbroken cable running the entire length?

Answer 1

Bus Topology

Question 2

What topology’s computers are connected to a central point with their own individual cable or wireless connections. It often has a central spot inhabited by a device like a hub, a switch, or an access point.

Answer 2

Star Topology

Question 3

What topology has computers directly connected to other computers within the same network and you can see it flows from computer to computer back to the source, with the network’s primary cable forming a ring?

Answer 3

Ring Topology

Question 4

What topology has a path from every machine to every other one in the network?

Answer 4

Mesh Topology

Question 5

What topology has a direct connection between two routers or switches, giving you one communication path?

Answer 5

Point to Point Topology

Question 6

What topology consists of a succession of connections between an interface on one router and multiple destination routers—-one point of connections to multiple points of connection.

Answer 6

Point-to-Multipoint Topology

Question 7

What topology has a combination of two or more types of physical or logical network topologies working together within the same network?

Answer 7

Hybrid Topology

Question 8

What is used to connect to a group of hosts together?

Answer 8

a LAN (Local Area Network)

Question 9

What is used to connect various LANs together?

Answer 9

a WAN (Wide Area Network)

Question 10

What are the three basic LAN topologies?

Answer 10

bus, ring and star

Question 11

What common WAN topology often results in multiple connections to a single site (leading to a high degree of fault tolerance) and has one-to-many connections?

Answer 11

Multiprotocol Label Switching (MPLS)

Question 12

What is the term for a device that shares its resources with other network devices?

Answer 12

Server

Question 13

What network model draws a clear distinction between devices that snare their resources and devices that do not?

Answer 13

Client-server

Question 14

Which network topology or connection type can be implemented with only two endpoints?

Answer 14

Point-to point

Question 15

What device is generally implemented as a star topology

Answer 15

hub or switch

Question 16

What does MPLS stand for?

Answer 16

Multiprotocol Label Switching

Question 17

What does WAN stand for?

Answer 17

Wide area network

Question 18

Will a computer that shares no resources most likely be connected to the backbone or to a segment?

Answer 18

A segment

Question 19

Which LAN topology is characterized by all devices being daisy-chained together with the device at each end being connected to only one other device?

Answer 19

Bus

Question 20

You need a network that provides centralized authentication for your user. Which logical topology should you use?

Answer 20

A client-server logical topology allows you to have a centralized database of users so that authentication ijs provided in one place.

Question 21

You need a topology that is scalable to use in your network. Which topology would you install?

Answer 21

To install a physical topology that provides ease of scalability, use a star network. This is a hub or switch device, and this is the most common LAN network today.

Question 22

Which of the following physical topologies has the most connections and is the least popular for LANs?

Answer 22

Only a mesh physical topology has point-to-point connections to every device, so it has more connections and is not a popular LAN technology.

Question 23

In a physical star topology, what happens when a workstation loses its physical connection to another device?

Answer 23

In a star topology, each workstation connects to a hub, switch, or similar central device but not to other workstations. The benefit is that when connectivity to the central device is lost, the rest of the network lives on.

Question 24

Which type of WAN technology uses labels, which enables priority of voice though the network?

Answer 24

Multiprotocol Label Switching has as many advantages as a LAN protocol. When labels are used, voice can have priority over basic data, for example.

Question 25

What is a logical grouping of network users and resources called?

Answer 25

A logical grouping of hosts is called a LAN, and you typically group them by connecting them to a hub or switch.

Question 26

What is a main concern when using peer-to-peer networks?

Answer 26

It is easy to relax about security in a peer-to-peer environment. Because of the trouble it takes to standardize authentication a piecemeal approach involving users’ personal preferences develops. There are no dedicated servers in a peer-to-peer network, and such a network can be created with as few as two computers.

Question 27

What is the difference between a LAN and a WAN?

Answer 27

A typical WAN connects two or more remote LANs together using someone else’s network (your ISP’s) and a router. Your local host and router see these networks as remote networks and not as local networks or local resources. Routers use proprietary serial connections for WANs.

Question 28

In what type of Network are all computers considered equal and do not share any central authority?

Answer 28

In a peer-to-peer network, all computers are considered equal. It is up to the computer that has the resource being requested to perform a security check for access rights to its resources.

Question 29

What advantage does the client-server architecture have over peer-to-peer?

Answer 29

In client-server networks, requests for resources go to a main server that responds by handling security and directing the client to the resource it wants instead of the request going directly to the machine with the desired resource (as in peer-to-peer).

Question 30

Which type of topology has the greatest number of physical connections?

Answer 30

In a mesh topology, there is a path from every connection to every other one in the network. A mesh topology is used mainly because of the robust fault tolerance it offers–if one connection goes on the blink, computers and other network devices can simply switch to one of the many redundant connections that are up and running.

Question 31

What type of topology gives you a direct connection between two routers so that there is one communication path?

Answer 31

With a point-to-point topology, you have a direct connection between two routers, giving you one communication path.

Question 32

Which network topology is a combination of two or more types of physical or two or more types of logical topologies?

Answer 32

A hybrid topology is a combination of two or more types of physical or logical network topologies working together within the same network.
