• B. Three (encapsulating, a link control protocol, ncp)
• C. Two (a link control protocol, simple network control protocol)
• D. One (simple network control protocol)

The PPP encapsulation ____________

• A. Provides for multiplexing of different network-layer protocols
• B. Requires framing to indicate the beginning and end of the encapsulation
• C. Establishing, configuring and testing the data-link connection
• D. Provides interface for handling the capabilities of the connection/link on the network

A Link Control Protocol (LCP) is used for ____________

• A. Establishing, configuring and testing the data-link connection
• B. Establishing and configuring different network-layer protocols
• C. Testing the different network-layer protocols
• D. Provides for multiplexing of different network-layer protocols

A family of network control protocols (NCPs) ____________

• A. Are a series of independently defined protocols that provide a dynamic
• B. Are a series of independently-defined protocols that encapsulate
• C. Are a series of independently defined protocols that provide transparent
• D. The same as nfs

Choose the correct statement from the following.
