Ethical Hacking Essentials Practice Test

Which component is used to connect wireless devices to a network and functions as a switch between wired and wireless networks?

1. Network switch

2. Access point

3. Router

4. Hub

The correct answer is: Access point

The correct choice is the access point, as it serves a vital role in connecting wireless devices to a wired network. An access point acts as a bridge, enabling wireless clients to connect to the wired infrastructure of a network. It facilitates the extension of a wireless network beyond a limited range, allowing devices such as laptops, smartphones, and tablets to access network resources without a physical connection. Access points are typically equipped with their own networking capabilities, which include the ability to manage communication between devices and direct traffic appropriately. Unlike a network switch, which primarily connects wired devices and operates at Layer 2 of the OSI model, an access point specifically addresses the requirements of wireless connections. Furthermore, while routers do facilitate wireless connectivity as well, their primary function is to route traffic between different networks (e.g., from a local network to the internet), rather than just connecting devices within a local wireless environment. A hub, being an outdated technology, simply broadcasts incoming packets to all ports without any intelligence or management of traffic, making it less efficient compared to a switch or access point. Therefore, the access point is uniquely positioned to integrate both wired and wireless networks effectively.
