Step-by-step explanation:
The subject of this question is Computers and Technology and the grade level is High School. The correct answer to the question is PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is typically used to initiate a session with a DSL service provider. Frames are encapsulated into Ethernet frames for transmission to the service provider. However, because these frames are not encrypted, PPPoE cannot provide a secure connection between a remote location and a company headquarters.
