Answer: a
Explanation: Both HDLC and PPP both are Data link layer protocol.

2. Which protocol does the PPP protocol provide for handling the capabilities of the connection/link on the network?
a) LCP
b) NCP
c) Both LCP and NCP
d) TCP

Answer: c
Explanation: LCP and NCP are the PPP protocol provide for handling the capabilities of the connection/link on the network.

3. The PPP protocol
a) Is designed for simple links which transport packets between two peers
b) Is one of the protocols for making an Internet connection over a phone line
c) Both Is designed for simple links which transport packets between two peers & Is one of the protocols for making an Internet connection over a phone line
d) None of the mentioned

Answer: c
Explanation: The PPP protocolis designed for simple links which transport packets between two peers and one of the protocols for making an Internet connection over a phone line.

4. PPP provides the _______ layer in the TCP/IP suite.
a) Link
b) Network
c) Transport
d) Application

Answer: a
Explanation: PPP provides thelinklayer in the TCP/IP suite.

5. PPP consists of ________components
a) Three (encapsulating, the Domain Name system)
b) Three ( encapsulating, a link control protocol, NCP )
c) Two ( a link control protocol, Simple Network Control protocol)
d) None of the mentioned

Answer: b
Explanation: PPP consists of three (encapsulating, a link control protocol, NCP)
Components.

6. 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) None of the mentioned

Answer: a
Explanation: The PPP encapsulationprovides for multiplexing of different network-layer protocols.

7. 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) None of the mentioned

Answer: a
Explanation: A Link Control Protocol (LCP) is used for establishing, configuring and testing the data-link connection.

8. 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

Answer: b
Explanation: A family of network control protocols (NCPs)are a series of independently-defined protocols that encapsulate.

9. Choose one from the following
a) PPP can terminate the link at any time
b) PPP can terminate the link only during the link establishment phase
c) PPP can terminate the link during the authentication phase
d) None of the mentioned

Answer: a
Explanation: PPP can terminate the link at any time because it works on the data link layer protocol.

10. The link necessarily begins and ends with this phase. During this phase, the LCP automata will be in INITIAL or STARTING states
a) Link-termination phase
b) Link establishment phase
c) Authentication phase
d) Link dead phase
Answer: d
Explanation: The link necessarily begins and ends with this phase. During this phase, the LCP automata will be in INITIAL or STARTING states link dead phase.
