350-401 Question 278
Single answerA network engineer is tasked with configuring a wireless network for a remote branch office. The branch office requires a secure connection for all users, and the engineer has decided to use a Pre-Shared Key (PSK) for authentication. Which configuration step is critical to ensure proper security when using PSK on the wireless network?
- A
Use a complex and unique PSK that is shared only with authorized users
- B
Enable open authentication to allow all devices to connect
- C
Configure WPA3-Personal as the security protocol for the wireless network
- D
Broadcast the PSK in the SSID to simplify user access
Show answer and explanation
Correct answer: A
Explanation
Pre-Shared Key (PSK) is commonly used for wireless network authentication. To ensure the security of the network, the PSK must be complex, unique, and shared only with authorized users. Broadcasting the PSK or using open authentication would undermine the network's security, and while using secure protocols like WPA3-Personal is recommended, it does not replace the need for a strong PSK.
- A. Correct.
Correct. Using a complex and unique PSK enhances the security of the wireless network by making it difficult for attackers to guess or brute-force the key.
- B. Incorrect.
Incorrect. Open authentication does not require credentials, which makes the network vulnerable to unauthorized access and security breaches.
- C. Incorrect.
Incorrect. While WPA3-Personal is a secure protocol, it is not specifically related to the correct configuration of the PSK itself. The focus of this step is on the PSK's complexity and confidentiality.
- D. Incorrect.
Incorrect. Broadcasting the PSK in the SSID would compromise the security of the wireless network by exposing the key to anyone within range.
