TestOut: ITSP 136 A+ 11.1 Networking Overview 11.4 Practice Questions

Which of the following network components is responsible for converting digital data into a signal that can be transmitted? Answer Transmission medium Protocol Switch Network interface

Network interface: Devices are connected together using a transmission medium. Examples include twisted pair cabling, fiber optics, or wireless radio signals. They do not convert the data into a digital signal.

Which of the following is a network that uses internet technologies, but the data and services are only available to the hosts connected to the private network? Answer Extranet Intranet Internetwork Subnet

Intranet

You are a junior network technician for a small consulting firm. You have recently learned about IP addressing and run the ipconfig command on your local computer. The output from the command is: IPv4 Address..... 192.168.0.52 Subnet Mask..255.255.255.0 Default Gateway..192.168.0.1 Which of the following is the host ID? Answer 192.168.0.1 192.168.0 255.255.255 52

Match each network type on the left with the appropriate description on the right. Each network type may be used once, more than once, or not at all. Drag Metropolitan Area Network (MAN) Wireless Local Area Network (WLAN) Wide Area Network (WAN) Personal Area Network (PAN) Local Area Network (LAN) Drop A network in a small geographic area that typically uses wires to connect systems together. A small network used for connecting devices, such as a notebook computer, a wireless headset, a wireless printer, and a smartphone. A network that is typically owned and managed by a city as a public utility. A group of networks that are geographically isolated, but are connected to form a large internetwork. Similar to a standard LAN, but uses radio signals instead of wires to connect systems together. A network that covers an area as small as a few city blocks to as large as an entire city. A set of subnets connected to each other, typically by wires, using at least one router.

Local Area Network (LAN) : A network in a small geographic area that typically uses wires to connect systems together. Personal Area Network (PAN): A small network used for connecting devices, such as a notebook computer, a wireless headset, a wireless printer, and a smartphone. Metropolitan Area Network (MAN): A network that is typically owned and managed by a city as a public utility. Wide Area Network (WAN): A group of networks that are geographically isolated, but are connected to form a large internetwork. Wireless Local Area Network (WLAN: Similar to a standard LAN, but uses radio signals instead of wires to connect systems together.

Which of the following terms refers to a network resource sharing model that uses access control lists saved on each computer? Answer Client/server Peer-to-peer Intranet Extranet

Peer-to-peer Access to shared resources are controlled separately on each computer in the peer-to-peer model (a Windows peer-to-peer network is called a workgroup. For example, each computer in a peer-to-peer network maintains its own set of user accounts.

A group of workers in an office space communicate with each other on their smartphones and tablet devices through an ad hoc network linked using Bluetooth technology protocols. Which of the following network types is in use? Answer Local Area Network (LAN) Personal Area Network (PAN) Metropolitan Area Network (MAN) Wide Area Network (WAN)

Personal Area Network (PAN)

Which of the following network types uses special hardware to provide high-speed access to storage across the network? Answer Client-server network Storage area network Local area network Peer-to-peer network

Storage area network A storage area network (SAN) is a special type of network that provides high-speed access to storage across the network. Specialized hardware is used to store and provide access to needed data. In a peer-to-peer network, each host can provide network resources to other hosts or access resources located on other hosts. It does not use special hardware to provide high-speed access to storage across the network. A local area network is a network in a small geographic area, like an office. A LAN typically uses wires to connect systems together. It does not use special hardware to provide high-speed access to storage across the network. 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. It does not use special hardware to provide high-speed access to storage across the network.

Which of the following defines which network a device is connected to? Answer Protocol Subnet mask Host ID Network ID

Subnet mask Oftentimes a large network will be split into smaller networks called subnets. The subnet mask defines which network a host belongs to.

You are a junior network technician for a small consulting firm. Your team recently split the network into smaller subnets, one for each department. One of your users, Jaclyn in HR, is trying to access shared files from Tom's computer in the sales department. Jaclyn states she was able to previously access these files. As part of your troubleshooting, you verify that both Tom and Jaclyn can access the network printer in their departments. Which of the following would be the MOST likely reason Jaclyn is unable to access files on Tom's computer? Answer Jaclyn has an invalid IP address. Tom and Jaclyn are no longer on the same subnet. Tom has an invalid IP address. The subnet mask has been misconfigured.

Tom and Jaclyn are no longer on the same subnet. Because Jaclyn and Tom are both still able to access the network printer in their departments, this shows that their IP addresses and subnet masks are valid.

You are working as an installer for a small IT company. One of your residential clients has purchased some IoT devices and you have been tasked with installing them for the client. These IoT devices will be networked together in a small network. Each device will connect to each other and act a relay for the network signal so additional network infrastructure will not be needed. Which of the following best describes this type of network? Answer Wireless mesh network Local area network Personal area network Wireless wide area network

Wireless mesh network A wireless mesh network (WMN) is a group of wireless mesh nodes that communicate with one another to share the network connection across a large area. Each device in the WMN uses the others as relays to avoid the need for infrastructure
