Explanation
IP phones support three distinct methods for obtaining an IP address: PPPoE (A), DHCP (C), and Static IP (D). DHCP is the most common, allowing phones to automatically receive an address from a server - ideal for large deployments. Static IP lets administrators manually assign a fixed address, useful when consistent addressing is required. PPPoE is supported on some IP phone models, particularly when connecting through ISP infrastructure that requires authentication before granting an address.
Why B is wrong: ADSL is a physical transmission technology (a type of broadband connection over copper telephone lines), not an IP address assignment method. It describes how data travels, not how an address is obtained - it belongs to a different layer entirely.
Memory tip: Think "ways to get an address" - DHCP (automatic), Static (manual), PPPoE (authenticated). ADSL is the pipe, not the label on your door.
