Answer :
Before a wireless device can communicate over a wireless LAN network, it must complete a series of stages to ensure proper connection and security. The stages are as follows:
Discover a Wireless AP: The first step a wireless device performs is to scan the surrounding area to find available wireless Access Points (APs). This is typically done using the device's wireless network adapter, which constantly listens for wireless networks within range.
Authenticate with the AP: Once a potential AP is discovered, the device attempts to authenticate itself with the network. Authentication is a process that involves verifying the identity of the user or device, which can be done using various methods such as open systems, shared keys, or more secure options like WPA/WPA2 systems.
Associate with the AP: After successful authentication, the device proceeds to associate with the AP. This association establishes a connection between the device and the AP, allowing for data packets to be sent and received over the network.
Thus, the correct sequence of stages for a wireless device to communicate over a wireless LAN is: discover a wireless AP, authenticate with the AP, and then associate with the AP. Therefore, the correct multiple-choice option is:
- Discover a wireless AP, authenticate with the AP, associate with the AP.
Understanding these stages is crucial because they ensure that the wireless device connects securely and reliably to the network, protecting both user data and network integrity.
