Network Hardware (Practice Test)

How do a router and switch differ when handling a message? 1. The router will purposefully drop messages if message traffic exceeds its capacity. 2. Both a router and a switch use the message's destination address to select the line to route the incoming message to. 3. The switch will purposefully drop messages if message traffic exceeds its capacity. 4. There is no difference in how a router and a switch handle messages.

Which of the following statements is true of computer networks? 1. Computer networks allow individuals to share many types of resources. 2. Computer networks allow individuals to share hardware such as printers, but not software. 3. Computer networks are not useful unless they are connected to the internet. 4. Computer networks are inherently secure.

What is the most common type of network connection in use today? 1. Fiber optic cable and radio towers 2. Fiber optic and UTP 3. Coaxial cable and radio towers 4. Radio towers and satellite

2

Which of the following best describes the benefits of a star network topology? 1. In a star network, every device has a point-to-point connection with every other device in the network. This allows any device to communicate with any other device. 2. It is easy to add (or remove) devices on a star network and maintain the efficiency of message transferal. 3. All devices in a star network have a single point-to-point connection with the neighboring computers in the network. 4. A star network requires a dedicated device (server, hub, or switch) which makes communication more efficient.

2

Which of the following communication system hardware devices is commonly used as a wireless access point? 1. hub 2. router 3. switch 4. radio waves

2

Which of the following describes local computers only? 1. Servers are often this type of computer. 2. Is a person that a person is physically at. 3. Is often a part of a computer network. 4. Is a computer that is accessed over the network.

2

Which of the following is NOT a characteristic of a bus network topology? 1. All messages travel along a single cable. 2. Is one of the more simple types of network topographies. 3. Expensive compared to other topologies. 4. Is a very reliable form of network.

3

Which of the following is the best definition of a computer network? 1. A computer network consists of one computer connected wirelessly to a printer. 2. A computer network consists of a number of computers connected via a device that allows them to connect to the internet. 3. A computer network is a collection of computers and computer resources (e.g., printers, file servers) connected in such a way that the computers can communicate with each other and their resources. 4. A computer network consists of two or more computers linked together that share devices such as printers and file servers but they are not able to share software.

3

Which of the following servers can generate reports from client queries? 1. web server 2. mail server 3. database server 4. file server

3

Which of the following type of transmission is paired correctly with the given media? 1. coaxial cable - radio waves 2. coaxial cable - light impulses 3. fiber optic cable - light impulses 4. fiber optic cable - voltage

3

Which of the following types of networks has each device in the network connected in a single point-to-point connection with a central HUB? 1. ring network 2. bus network 3. star network 4. mesh network

3

Why would it be desirable to use a switch as opposed to a hub in a network? 1. Because switches only transfer information to specific computers within a network and not all of the computers, the bandwidth used within a switch is more than that of a hub. 2. Because a switch is a more powerful device, it can be used over longer distances compared to a hub. 3. Because switches only transfer information to specific computers within a network and not all of the computers, the bandwidth used with a switch is less than that of a hub. 4. Because a switch is a more powerful device, it cannot be used over longer distances compared to a hub.

How do virtual machines support a business computing ecosystem? 1. A virtual machine (VM) is a server that users can log into and use different OSs and applications associated with the different OSs. 2. A virtual machine (VM) is a separate computer that provides users access to an OS different from their primary computer. Being able to have access to a computer with a different OS facilitates collaboration in the business ecosystem. 3. A virtual machine (VM) is a broadcasting device that facilitates communication across a network, thus supporting a business computing ecosystem. 4. A virtual machine (VM) is made available by software and permits a computer to run multiple OSs. In a business ecosystem, this allows for improved collaboration that is not restricted by platform software.

4

In a client-server network, what is the role of the server? 1. The role of the server is to maintain connections to remote servers. 2. The role of the server is the same as the role of the client because all of the computers on this type of network are equal. 3. The role of the server is the send out requests for information. 4. The role of the server is to take requests from the client and send back the requested information.

4

Which of the following servers monitors requests, but doesn't send files in return? 1. FTP server 2. file server 3. web server 4. print server

4

Which of the following are characteristics of a packet-switched network? 1. The path exists during the entire transmission, allowing communication in either direction to occur simultaneously. 2. The choice of pathway is based on network availability and amount of message traffic. 3. The route is established one branch at a time 4. Both 1 and 2 5. Both 2 and 3
