To which protocol does PPPoE relate?

  1. Internet Protocol (IP)

  2. Point to Point Protocol (PPP)

  3. Frame Relay Protocol

  4. Spanning Tree Protocol

The correct answer is: Point to Point Protocol (PPP)

PPPoE, or Point-to-Point Protocol over Ethernet, directly relates to the Point-to-Point Protocol (PPP), which is essential for establishing direct connections between two network nodes. PPP is used for encapsulating network layer protocols like IP, facilitating the transmission of packets over a point-to-point link. In the case of PPPoE, it effectively allows PPP to be used over Ethernet networks, enabling DSL (Digital Subscriber Line) to establish connections to the Internet. This encapsulation is crucial for broadband connections, as it combines the reliable session management features of PPP with the operational capabilities of Ethernet environments. Understanding the linkage between PPPoE and PPP is fundamental for networking professionals, especially when configuring Internet connections in various environments, as it highlights how different protocols interact and function within network architectures.
