Exam 350-401 topic 1 question 296 discussion

IEEE 802.1X is an IEEE Standard for port-based Network Access Control (PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN. The given answer is correct

WebAuth, like MAB, can be used as a fallback authentication mechanism for 802.1x. If both MAB and WebAuth are configured as fallbacks for 802.1x, when 802.1x times out, a switch first attempts to authenticate through MAB, and if it fails, the switch attempts to authenticate with WebAuth. So you must select 802.1X as the main authentication method

i think B is the correct answer

So what is the correct answer please ? because if the answer was 802.1x, how the printer can be authenticated without using MAB in this case ?

The correct answer is C. A is for Layer 2, solely based on device MAC address. C is for WLC Layer 3 Authentication D is for Layer 2 Deploying IEEE 802.1X is an excellent approach to enhancing network security through Network Access Control (NAC). 802.1X is a standard for port-based network access control that provides strong authentication and authorization mechanisms, allowing only authorized users and devices to connect to a network.

MAB might be needed for the printer(s), but not for the rest of the network. For the rest, need 802.1x

802.1x is port security. Mab is kindergarten level security

I go with MAB because no details of the printer and MAB is the safer deployment.

"802.1x", it's even used with WPA2 Enterprise, in a RADIUS server. https://www.securew2.com/solutions/wpa2-enterprise-and-802-1x-simplified

Honestly, not sure about 802.1x. Obviously 802.1x it is the recommended method for an enterprise environment. But in the image there is a printer, some do not support a 1x supplicant. So with MAB auth with make sure that anytype of device will be able to authenticate and access. It is a bit tricky question.

What does the picture have to do with anything ? Answer is the same lol

Is the printer able to authenticate?

Provided answer is correct
