An engineer has deployed a single Cisco 5520 WLC with a management IP address of
172.16.50.5/24. The engineer must register 50 new Cisco AIR-CAP2802I-E-K9 access points to the WLC using DHCP option 43. The access points are connected to a switch in VLAN 100 that uses the 172.16.100.0/24 subnet. The engineer has configured the DHCP scope on the switch as follows:
Network 172.16.100.0 255.255.255.0
Default Router 172.16.100.1
Option 43 ASCII 172.16.50.5
The access points are failing to join the wireless LAN controller. Which action resolves the issue?

• A.configure option 43 Hex F104.AC10.3205
• B.configure option 43 Hex F104.CA10.3205
• C.configure dns-server 172.16.50.5
• D.configure dns-server 172.16.100.1
