Click the Exhibit. You have configured 802.1X single supplicant mode on the access switch. The VoIP phone does not support 802.1X authentication. Referring to the exhibit, which statement is true?
A.
MAC bypass must be configured for the VoIP phone for this solution to work.
B.
Authentication must be changed to multiple supplicant mode for this solution to work.
C.
The VoIP phone will be able to communicate over the network after the workstation authenticates.
D.
The VoIP phone will not be able to communicate over the network.
"If an IP phone and a user’s PC are connected to the same switch port and only one of the two devices is 802.1X capable, use single supplicant mode. Single supplicant mode authenticates the 802.1X-capable device and freely permits traffic from other devices without further authentication."
in that link you sent above
If an 802.1X-compatible IP telephone does not have an 802.1X host but has another 802.1X-compatible device connected to its data port, you can connect the phone to an interface in single supplicant mode. In single supplicant mode, the 802.1X process authenticates only the first supplicant. All other supplicants who connect later to the interface are allowed full access without any further authentication. They effectively “piggyback” on the first supplicant’s authentication.
so the answer is C?
I think boyseven777 is actually right
If an IP telephone does not support 802.1X, you can configure VoIP to bypass 802.1X and LLDP-MED and have the packets forwarded to a VoIP VLAN.
To configure VoIP on an EX Series switch to support an IP phone that does not support 802.1X authentication, you must either add the MAC address of the phone to the static MAC bypass list or enable MAC RADIUS authentication on the switch.
