  1. Correct answer is D:

    “802.1X and Web/MAC authentication normally do not allow authenticated clients (the phone) and unauthenticated clients (the PC) on the same port.”

    1. there is no drops traffic, just moved to guest vlan access.
      Unauthenticated VLAN access (guest VLAN access)
      If the PC is unauthenticated, it needs to have access to the insecure guest VLAN (unauthenticated VLAN) that has been configured for 802.1X or Web/MAC authentication. 802.1X and Web/MAC authentication normally do not allow authenticated clients (the phone) and unauthenticated clients (the PC) on the same port.
