350-401 Question 265
Single answerYour organization is deploying a new wireless network, and you are tasked with ensuring that it is secured against unauthorized access. You configure WPA3-Enterprise on the wireless LAN controller (WLC). During testing, some devices fail to connect. What is the most likely reason for this issue?
- A
The devices do not support WPA3 and need to fall back to WPA2.
- B
WPA3-Enterprise requires a pre-shared key, which was not configured.
- C
The devices are using outdated firmware that does not support 802.1X authentication.
- D
WPA3-Enterprise requires all devices to use Opportunistic Wireless Encryption (OWE).
Show answer and explanation
Correct answer: C
Explanation
WPA3-Enterprise enhances wireless security by requiring 802.1X authentication and strong encryption protocols. Devices attempting to connect must support WPA3-Enterprise features, which often require up-to-date firmware. If devices are using outdated firmware, they may not support the necessary protocols, leading to connectivity failures. This is the most likely reason for the issue described in the scenario.
- A. Incorrect.
This is a plausible reason for connection failures, as devices that do not support WPA3 may need to fall back to WPA2 if configured to do so. However, the question specifically states WPA3-Enterprise is configured, which uses 802.1X authentication, not fallback mechanisms.
- B. Incorrect.
WPA3-Enterprise does not use a pre-shared key (PSK); it relies on 802.1X authentication protocols. Therefore, this is not the correct answer.
- C. Correct.
Outdated firmware could prevent devices from supporting WPA3-Enterprise and 802.1X authentication, leading to connectivity issues. This is the most likely cause in this scenario.
- D. Incorrect.
Opportunistic Wireless Encryption (OWE) is part of WPA3-Personal for securing open networks, not WPA3-Enterprise. Thus, this option is incorrect.
