Which must be taken into account if a customer wants to use the DHCP collector with 802.1X authentication?
When using 802.1X authentication, the client device does not have an IP address until after successful authentication. Since DHCP fingerprinting relies on information that is available only after the client receives an IP address, it is necessary to grant the client limited access initially. This limited access allows the device to obtain an IP address, enabling the DHCP fingerprinting process to gather necessary information before full network access is determined based on the device type.
Correct answer is D
Was thinking A at first, but that is just the basic definition of DHCP fingerprinting. Correct answer: D - seems more correct given that the context given is DHCP with 802.1X. Closest reference I can find: Aruba ClearPass Fundamentals v20.11 - Page 270. Summarizes the process a client goes through connecting to an access point with DHCP Collection configured.
D is correct
The 802.1x auth request is layer 2, the device doesn't have IP address yet.
