Suggested Answer:F🗳️
Keep the following in mind when troubleshooting wireless DHCP issues: Option 43 is used to inform the DHCP client of the WLC AP-management IP address. Use the ip dhcp pool command for VLAN 20 and enter the AP-management IP address as part of option 43. The command format is option 43, followed by the correct IP address in hexadecimal format, as shown in the example. If there is only one WLC management address, the Length is 04 (hex), and in this case the WLC management IP address is 10.10.10.10, which is 0a0a0a0a (hex).
E
1. The dynamic AP management wasnt enabled on the VLAN 20. Dynamic AP Management ACTS LIKE an AP-Manager interface. (For obsolete WLC)
2. The option 43 must a hex (for any type AP) EXCEPT VxWorks 1000 Series
3. References :

D would be correct for Cisco Aironet 1000 Series APs (VxWorks) (1010/1020/1030/1505/1510) Series ONLY.
The correct answer for all other Cisco Aironet APs would be:
ip dhcp pool vlan20 option 43 hex f1040a0a0a0a

Correct answer is D, which matches the description of why it is correct.
The AP and Controller are on different subnets so the AP will need option 43 to know the WLC MGMT interface.
The command syntax while configuring the DHPC pool is: option 43 ascii [IP address(es)]
Answer F makes no sense becuase the DHCP pool already exists, so this command does nothing.
Also, nowhere in the screenshots does it show that the WLC MGMT interface has the IP 10.10.10.10, that must be assumed.
