Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

B is correct because DHCP option 150 is the Cisco-specific option that carries the TFTP server IP address, which Cisco IP phones use to download their configuration files. Option 55 is the parameter request list. Option 99 is for the tftp server name (not IP). Option 105 is for the swap server (used in older systems).
