The Customer Has an Office Environment with Users Who Have

The customer has an office environment with users who have laptops that can connect with wired or wireless. Users also bring one or two of their own devices. An architect creates a proposal with Aruba AP-325s, 7210 Mobility Controllers (MCs) , a Mobility Master (MM) , and Aruba 2930M switches at the access layer to support the laptops and APs. The architect plans to recommend 802.1X authentication without tunneled node on Aruba 2930M switch ports that connect to laptops. What is one advantage of this form of authentication?

A) ensures that Aruba firewall policies apply to wired user traffic
B) prevents users from connection attempts with more than three devices
C) enables user access control and ensures only authorized users connect
D) provides a second layer of protection for wireless users at the internal perimeter
