Answer: C

Explanation:

The AP sends a challenge text to the station.

The Access Point (AP) initiates the authentication process by sending a challenge text to the station (client device).

The station connects to the network.

The station (client device) associates with the wireless network by connecting to the AP.

The station encrypts the challenge text using its configured 128-bit key and sends the encrypted text to the AP.

The station encrypts the challenge text using the shared secret key (configured on both the station and the AP).

It then sends the encrypted challenge text back to the AP.

The station sends an authentication frame to the AP.

The station constructs an authentication frame containing the encrypted challenge text.

This frame is sent to the AP for verification.

The AP uses its configured WEP key to decrypt the encrypted text and compares it with the original challenge text.

The AP decrypts the received encrypted challenge text using its configured WEP (Wired Equivalent Privacy) key.

If the decrypted text matches the original challenge text, the station is authenticated successfully.

Therefore, the correct sequence is

C. 4―>1―>3―>5―>21. This order ensures that the challenge

text is exchanged securely and verified by both the station and the AP during the shared key

authentication process.
