300-430 Question 188
Single answerA network administrator is tasked with securing wireless client connectivity on a corporate WLAN. The clients must authenticate using their unique credentials, and data transmitted between the clients and the access points must be encrypted. Additionally, the solution should provide mutual authentication between the client and the network. Which security mechanism is the most appropriate for this scenario?
- A
WPA2-PSK
- B
WPA3-Enterprise with 802.1X
- C
WEP with a shared key
- D
Open authentication with MAC filtering
Show answer and explanation
Correct answer: B
Explanation
WPA3-Enterprise with 802.1X is the most secure and appropriate option for this scenario because it meets all the requirements: unique credentials for clients, strong encryption for data, and mutual authentication using RADIUS and certificates or credentials. Other options fail to meet one or more of these requirements or are considered insecure.
- A. Incorrect.
WPA2-PSK provides encryption but relies on a pre-shared key for authentication, which does not support unique credentials or mutual authentication.
- B. Correct.
WPA3-Enterprise with 802.1X provides strong encryption, supports unique credentials via RADIUS, and ensures mutual authentication between the client and network.
- C. Incorrect.
WEP is outdated and insecure, offering weak encryption and no mutual authentication or support for unique credentials.
- D. Incorrect.
Open authentication with MAC filtering offers no encryption or authentication beyond MAC address filtering, which is easily bypassed.
