200-301 Question 455
Select 3A network administrator is tasked with configuring a new WLAN for a company's guest network using WPA2-PSK for authentication. Using the GUI of a wireless LAN controller, which of the following steps must the administrator complete to successfully configure and secure the WLAN?
- A
Set the SSID for the WLAN in the basic settings.
- B
Configure WPA2 as the security type and specify a pre-shared key.
- C
Enable 802.1X authentication for the WLAN.
- D
Assign the WLAN to a VLAN to segment guest traffic.
- E
Disable broadcast of the SSID to enhance security.
Show answer and explanation
Correct answers: A, B, D
Explanation
To configure a WLAN with WPA2-PSK on a wireless LAN controller's GUI, the administrator must set the SSID for the network, configure WPA2 as the security type with a pre-shared key, and assign the WLAN to a VLAN for proper traffic segmentation. 802.1X is not applicable for PSK setups, and disabling SSID broadcast is optional and does not provide substantial security benefits.
- A. Correct.
Correct: Setting the SSID is a necessary step to define the wireless network name and make it identifiable to users.
- B. Correct.
Correct: Configuring WPA2 and a pre-shared key ensures that the WLAN is secured with strong encryption and authentication.
- C. Incorrect.
Incorrect: 802.1X authentication is not applicable for WPA2-PSK, which uses a pre-shared key instead of centralized authentication.
- D. Correct.
Correct: Assigning the WLAN to a VLAN provides proper network segmentation, which is essential for guest traffic.
- E. Incorrect.
Incorrect: Disabling SSID broadcast is not a requirement for WPA2-PSK configuration and does not significantly enhance security, as the SSID can still be detected using other methods.
