Question

You have just signed up for internet access using a local provider that gives you a fiber optic line into your house. From there, Ethernet and wireless connections are used to create a small network within your home.

Which of the following protocols would be sued to provide authentication, authorization, and accounting for the internet connection?

- PPP
- L2TP
- ICA
- PPPoE
- RDP

Answer 1

PPPoE (Point-to-Point Protocol over Ethernet) is the protocol typically used to provide authentication, authorization, and accounting for a home internet connection over a fiber optic line with Ethernet and wireless networks.

Step-by-step explanation:

To provide authentication, authorization, and accounting for an Internet connection, particularly in the context of a home network using both Ethernet and wireless connections, the protocol that would likely be used is PPPoE (Point-to-Point Protocol over Ethernet). This protocol is commonly employed by Internet service providers to manage the connections of individual users. It allows a modem to establish a direct connection to the service provider over Ethernet, authenticating the user and ensuring that their billing and usage data are accurately recorded.

Protocols such as PPP (Point-to-Point Protocol) and L2TP (Layer 2 Tunneling Protocol) are also related to internet connectivity and VPN services, but PPPoE is specifically designed for Ethernet networks. Other protocols mentioned, like ICA (Independent Computing Architecture) and RDP (Remote Desktop Protocol), are used for different purposes such as remote computer access and do not deal with Internet service authentication.
