What does PPPoE stand for?

PPPoE stands for Point-to-Point Protocol over Ethernet. This technology is used primarily for establishing a direct connection between two network nodes over an Ethernet infrastructure. It encapsulates Point-to-Point Protocol frames within Ethernet frames, allowing for the transmission of data across a broadband connection.

The main purpose of PPPoE is to enable users to connect to the Internet through a modem or router using a username and password for authentication, which makes it suitable for DSL (Digital Subscriber Line) services. By understanding the correct meaning of PPPoE, technicians can better troubleshoot connection issues and configure network settings for users.

The other options do not accurately reflect the accepted terminology or functional purpose of this technology, as they either create incorrect terminology or describe non-existent protocols.
