2.1.7 Section Quiz

Question 1

You’ve implemented a network where hosts are assigned specific roles, such as file sharing and printing roles. Other hosts access those resources, but they don’t host services of their own. Which type of network do you have?

1. Client-Server
2. Peer-to-peer
3. Intranet
4. Extranet

Answer 1

1. Client-Server

In a client-server network, hosts have specific roles. For example, some hosts are assigned server roles, which allow them to provide network resources to other hosts. Other hosts are assigned client roles, which allow them to consume network resources.

In a peer-to-peer network, each host can provide network resources to other hosts or access resources located on other hosts, and each host is in charge of controlling access to those resources.

An intranet is a private network that uses internet technologies. Services on an intranet are only available to hosts that are connected to the private network.

An extranet is a private network that uses internet technologies, but whose resources are made available to external (but trusted) users. For example, you might create a website on a private network that only users from a partner company can access.

Question 2

Which of the following geographic network types is typically managed by a city as a public utility?

1. Wide area network (WAN)
2. Personal area network (PAN)
3. Local area network (LAN)
4. Metropolitan area network (MAN)

Answer 2

4. Metropolitan area network (MAN)

A metropolitan area network (MAN) is a network that can cover an entire city. A city typically owns and manages a MAN as a public utility.

A PAN is a small network for communication between personal devices. A LAN is contained to an office and managed by a business.

A WAN is a collection of LANs that are connected together to form a large internetwork. WAN connections are typically managed by an ISP.

Question 3

You’ve implemented a network where each device provides all other devices on the network with access to Shared files. Which type of network do you have?

1. Peer-to-peer
2. Client-server
3. Multiple access
4. Polling

Answer 3

1. Peer-to-peer

In a peer-to-peer network, each host can provide network resources to other hosts or access resources located on other hosts, and each host is in charge of controlling access to those resources.

In a client/server network, hosts have specific roles. For example, some hosts are assigned server roles, which allow them to provide network resources to other hosts.

Other hosts are assigned client roles, which allow them to consume network resources. Polling is a media access method where a single device grants permission to other devices to access the network.

Multiple access describes a media access method where each device determines when the medium is free.

Question 4

You have a network that uses a logical bus topology. How do messages travel through the network?

1. Messages are broadcast to all devices connected to the network
2. Messages are sent directly to the correct destination device
3. Messages travel from one device to the next until they reach the destination device
4. Messages are sent to a central device that forwards them to the

Answer 4

1. Messages are broadcast to all devices connected to the network

Messages sent using a physical bus topology are broadcast to all devices on the network.

The device in the middle of a star topology, which is typically a hub, receives the message and forwards it on to all other devices.

In a ring topology, messages travel from one device to the next until they reach the destination device.

Question 5

You have a network that uses a logical ring topology. How do messages travel through the network?

1. Messages are sent to all devices connected to the network
2. Messages are sent directly to the destination device only
3. Messages travel from one device to the next until they reach the destination device
4. Messages are sent to a central device that forwards them to the destination devices

Answer 5

3. Messages travel from one device to the next until they reach the destination device

In a logical ring topology, messages travel to each device in turn. If the message isn’t intended for that device, the message is forwarded to the next device on the network.

Messages sent using a physical bus topology are broadcast to all devices on the network.

The device in the middle of the star topology, which is typically a hub, receives the message and forwards it on to all other devices.

Question 6

Your manager has asked you to implement a wired network infrastructure that will accommodate failed connections. You don’t have a large budget, so you decide to provide redundancy for only a handful of critical devices. Which of the following network topologies should you implement?

1. Full mesh
2. Star
3. Bus
4. Partial mesh

Answer 6

4. Partial mesh

In a partial mesh topology, only some redundant paths exist. A partial mesh topology is more practical and less expensive than a full mesh topology.

In a full mesh topology, every device has a point-to-point connection with every other device. This provides full redundancy, but it’s expensive and impractical.

A star topology connects network devices to the network with a single patch cable. A patch cable failure makes the connected device unavailable.

A bus topology has a single point of failure. If there’s a break in the network media, the network becomes unavailable.

Question 7

Which of the following topologies connects all devices to a trunk cable?

1. Bus
2. Star
3. Ring
4. Mesh

Answer 7

1. Bus

A bus topology connects all devices to a trunk cable.

A ring topology connects neighboring nodes until they form ring.

A star topology uses a hub or switch to connect all network connections to a single physical location.

A mesh topology exists when there are multiple paths between any two nodes on a network.

Question 8

Your manager has asked you to implement a network infrastructure that will accommodate failed connections. Which of the following network topologies provides redundancy for a failed link?

1. Star
2. Bus
3. Ring
4. Mesh

Answer 8

4. Mesh

In a mesh topology, each network device is interconnected with all other network nodes. This creates
multiple data paths. If a link fails, the data has an alternate route to its destination.

A star topology connects network devices to the network with a single patch cable. A patch cable
failure makes the connected device unavailable.

A bus topology has a single point of failure. If there’s a break on the network medium, the network
becomes unavailable.

A single break on a physical ring topology disables the network.

Question 9

Which of the following topologies connects each device to a neighboring device?

1. Star
2. Mesh
3. Bus
4. Ring

Answer 9

4. Ring

In ring topologies, each device connects to a neighboring device so that a ring is formed.

The bus topology connects all devices to a trunk cable.

A star topology uses a hub or switch to connect all network connections to a single physical location.

A mesh topology exists when there are multiple paths between any two nodes on a network.

Question 10

You have a small network that uses a switch to connect multiple devices. Which physical topology are you using?

1. Ring
2. Bus
3. Mesh
4. Star

Answer 10

4. Star

A switch creates a network with a physical star topology. The physical star topology uses a logical bus
topology and sends messages to all the devices connected to the hub.

A mesh topology is a series of point-to-point links between devices.

A ring topology uses a central device called an MSAU.

A bus topology connects all devices to a trunk cable.
