Chapter 1: Introduction to Networks

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

2. C. 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.

3. D. 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.

4. B. 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.

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