A technician is tasked to prepare a conference room so that at least 20 guests will be able to wirelessly connect laptop computers to the company network. Which network device would be the best choice for this connectivity?

An access point is the best choice for providing wireless connectivity in a conference room for at least 20 guests. Access points are specifically designed to extend a wired network by enabling wireless devices to connect to it. They serve as a central hub for wireless communication, allowing multiple laptops to simultaneously connect without the need for cables.

In a scenario with numerous guests, an access point can support multiple connections and provide the necessary bandwidth, reducing potential network congestion. Furthermore, access points can be strategically placed to improve coverage and signal strength throughout the conference room, ensuring that all guests can connect easily and maintain a stable connection.

While a router can provide some level of connectivity, its primary function is to direct traffic between networks rather than facilitating large numbers of wireless device connections in a specific area. A switch, on the other hand, connects multiple wired devices within the same network segment, which doesn't address the need for wireless connectivity. Lastly, a bridge connects two network segments but does not provide the wireless access necessary for this specific scenario. Therefore, the access point is clearly the most appropriate device for this task.
