Question 45

You are asked to configure an 802.1X solution that supports dynamic VLAN assignment.

In this scenario, which two modes support using vendor-specific attributes (VSAs)? (Choose two.)

    Correct Answer: C, D

    In the context of configuring an 802.1X solution that supports dynamic VLAN assignment using vendor-specific attributes (VSAs), the two modes that support this functionality are single supplicant mode and multiple supplicant mode. Single supplicant mode allows one supplicant per port, whereas multiple supplicant mode allows multiple supplicants per port. These modes can utilize VSAs to dynamically configure VLANs, making them suitable for the desired 802.1X solution.

Should be B and D RADIUS attributes can also be used to change the supplicant mode for 802.1X authentication. Using a Juniper Networks vendor-specific attribute (VSA), you can set the supplicant mode to either single or single-secure: Juniper-AV-Pair = Supplicant-Mode-Single Juniper-AV-Pair = Supplicant-Mode-Single-Secure
