Answer 1

To calculate the DHCP Option 43 hex value for a Wireless LAN Controller (WLC) with the IP address 192.168.123.100, we need to follow the format specified for Option 43.

The format generally is:
- The first byte is the type of option, which is `f1` for vendor-specific options.
- The second byte indicates the length of the data that follows, which typically would be `04` for a 4-byte IP address.
- The next bytes represent the IP address in hexadecimal format.

The IP address 192.168.123.100 needs to be converted to hex:

- 192 in hex is C0
- 168 in hex is A8
- 123 in hex is 7B
- 100 in hex is 64

So the IP address 192.168.123.100 in hex would be C0A87B64.

Putting it all together:
- Type: F1
- Length: 04
- IP: C0A87B64

The final Option 43 value becomes **F104C0A87B64**.

Based on the provided options, the correct answer is:

**F104C0A87B64**.
