What term is used to describe the process of controlling data flow and ensuring a valid PPP connection?

1. Session establishment

2. Protocol negotiation

3. Link management

4. Data encapsulation

The correct answer is: Link management

The correct answer is link management. Link management is a critical aspect of the Point-to-Point Protocol (PPP) that involves overseeing the establishment, maintenance, and termination of the connection between two devices. This process ensures that data can flow smoothly and securely over the established link. It covers various tasks such as monitoring the link status, managing error corrections, and handling link challenges. While session establishment refers to the initiation of a connection, protocol negotiation involves determining the protocols to be used once the link is established. Data encapsulation pertains to the method of wrapping data packets with the necessary headers and trailers for transmission, which is a separate step in the data communication process. Therefore, link management is specifically focused on the ongoing control of that link, making it the term that best describes the process of managing data flow and ensuring a valid PPP connection.
