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

You have been asked to implement a network infrastructure that will accommodate failed connections. Which of the following network topologies provides redundancy for a failed link?

Mesh

You have implemented an ad hoc wireless network that doesn't employ a wireless access point. Every wireless network card can communicate directly with any other wireless network card on the network. What type of physical network topology has been implemented in this type of network?

Mesh

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

Messages are broadcast to all devices connected to the network. Messages sent using a physical bus topology are broadcast to all devices in the network. The device in the middle of the star (typically a hub) receives the message and forwards it on to all other devices.

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

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