What is the structure of PPP frame format?
PPP basically uses the same basic format as that of HDLC. PPP usually contains one additional field i.e. protocol field. This protocol field is present just after control field and before information or data field. PPP frame similar to HDLC frame, always begins and ends with standard HDLC flag.
What is PPP protocol explain PPP packet format?
Point-to-Point Protocol (PPP) is a TCP/IP protocol that is used to connect one computer system to another. Computers use PPP to communicate over the telephone network or the Internet. A PPP connection exists when two systems physically connect through a telephone line. You can use PPP to connect one system to another.
Which statement is true for the PPP protocol?
9. Choose the correct statement from the following. Explanation: PPP allows termination of the link at any time in any phase because it works on the data link layer which is the layer in control of the link of the communication.
What is the purpose of protocol field in the PPP frame?
The protocol field identifies the type of packet inside the frame. When PPP was created, this field allowed packets from many different Layer 3 protocols to pass over a single link. Today, the protocol type field still provides the same function, even for the support of two different versions of IP (4 & 6).
Which of the following protocols are used by the PPP protocol?
PPP operates using different network layer protocols (e.g., IPX and AppleTalk), whereas SLIP uses only TCP/IP-based IP. PPP and SLIP will encapsulate a datagram and other network layer protocol information over point-to-point links. These are called NCPs.
Which protocol does PPP identify the network layer protocol?
Network Control Protocol
Detailed Solution. The correct answer is NCP. Network Control Protocol (NCP) is used to help identify the Network layer protocol used in the packet.
Which of the following protocols are used by PPP protocol?
The following NCPs may be used with PPP: IPCP for IP, protocol code number 0x8021, RFC 1332. the OSI Network Layer Control Protocol (OSINLCP) for the various OSI network layer protocols, protocol code number 0x8023, RFC 1377. the AppleTalk Control Protocol (ATCP) for AppleTalk, protocol code number 0x8029, RFC 1378.
What are the three components of PPP?
PPP has the following three main components:
- a way to encapsulate multiprotocol datagrams;
- Link Control Protocol to establish, configure and test the data link connection; and.
- a group of separate network control protocols that establish and configure different types of network layer protocols.
Which two protocols are used in PPP?
PPP is designed to allow the simultaneous use of multiple network layer protocols, including IPv4 and v6, IPX, and AppleTalk. PPP operates using different network layer protocols (e.g., IPX and AppleTalk), whereas SLIP uses only TCP/IP-based IP.
Which two protocols provide authentication services for PPP choose two?

Which protocol does PPP identify the Network layer protocol Mcq?
9. What protocol does PPP use to identify the Network layer protocol? Explanation: Network Control Protocol is used to help identify the Network layer protocol used in the packet.
What is the frame format of PPP protocol?
The frame format of PPP protocol contains the following fields: Flag: The flag field is used to indicate the start and end of the frame. The flag field is a 1-byte field that appears at the beginning and the ending of the frame. The pattern of the flag is similar to the bit pattern in HDLC, i.e., 01111110.
What is the use of PPP protocol?
It is mainly used in point-to-point devices, for example, routers are point-to-point devices where PPP protocol is widely used as it is a WAN protocol not a simple LAN ethernet protocol. Flag: The flag field is used to indicate the start and end of the frame.
How many bits are in a PPP packet?
The Point-to-Point Protocol (PPP) Link Control Protocol (LCP), the Compression Control Protocol (CCP), Internet Protocol Control Protocol (IPCP), and other control protocols, contain an 8 bit Code field which identifies the type of packet.
What is the difference between control field and protocol field in PPP?
It is not a required field as PPP does not support the flow control and a very limited error control mechanism. The control field is a mandatory field where protocol supports flow and error control mechanism. Protocol: It is a 1 or 2 bytes field that defines what is to be carried in the data field.
