1The normal operation is for the DCE device to be sending out DISC (disconnect) frames at a time interval determined by its T-1 timer setting This indicates that it is ready to receive a call 2The DTE device will initialize the link with one command, the SABM, which initiates the DCE sending back an Unnumbered Acknowledgment 3The DTE starts sending data using information frames, each of which is acknowledged by RR frames RR frames are sent by the DCE and indicate that the receiver is ready for more information If the DCE has information to send to the DTE, it can do this using the same RR frame that acknowledged receipt of DTE data If the RR frame contains data, it is known as a piggyback acknowledgment 4If the DTE sends enough information to fill the buffers of the DCE, the DCE will send back a Receiver Not Ready (RNR) frame Upon receipt of a RNR frame, the DTE will remain idle for the length of its T-1 timer, then poll the DCE to see if it is ready 5The DCE will respond to a poll with more RNR packets until it has space in its buffer to take more data, at which time it will send an RR frame to allow the DTE to start sending more Information frames 6The link is cleared by the DTE sending a DISC (disconnect frame), which is responded to by an Unnumbered Acknowledgment The third layer protocol in X25 is called the Packet Layer Procedure (PLP) and provides the procedures for the control of virtual circuits within the X25 network The lower two layers have local significance, whereas the packet level has end-to-end significance, as illustrated in Fig 6-13

1 D The National ISDN 1 (NI-1) standard was defined by the industry so that users would not have to know the type of switch to which they are connected in order to buy equipment and software compatible with it A, B, and C are incorrect because NI-1 is the term used for ISDN 2 C PRI is intended for users with greater bandwidth requirements It requires T1 carriers to facilitate communications Normally, the channel structure contains 23 B channels plus one 64 Kbps D channel, for a total of 1536 Kbps A, B, and D are incorrect numbers of B channels

3 A The Serial Line Internet Protocol, or SLIP, is a communications protocol used for making a TCP/IP connection over a serial interface to a remote network SLIP was designed for connecting to remote UNIX servers across a standard phone line This protocol was one of the first of its kind, enabling a remote network connection to be established over a standard phone line B, C, and D are incorrect because IPX/SPX and NetBEUI cannot run over SLIP PPP is incorrect because it is not a network protocol, but a RAS protocol that competes with SLIP 4 B PPP established other standards, including asynchronous and bit-orientated synchronous encapsulation, network protocol multiplexing, session negotiation, and data-compression negotiation PPP also supports protocols other than TCP/IP, such as IPX/SPX and DECnet A, C, and D are incorrect because SLIP is limited to running on TCP/IP networks IPX and NetBEUI are standard network protocols, not protocols for RAS 5 A and B The following text explains the three components of PPP and their purpose: PPP uses the High-Level Data-Link Control (HDLC) protocol as the basis to encapsulate its data during transmission; PPP uses the Link Control Protocol (LCP) to establish, test, and configure the data link connection; various network control protocols (NCPs) are used to configure the different communications protocols This enables you to use different protocols such as TCP/IP and IPX over the same line simultaneously C and D are incorrect because they are not a part of the Point-to-Point Protocol 6 B The Internet Protocol Control Protocol (IPCP) is the NCP used to configure, enable, and disable the IP protocol modules at each end of the link A, C, and D are incorrect because B is correct and neither of the others exists

As previously noted, each IP network has a distinct network prefix and each host on an IP network has a distinct host address When two IP networks are interconnected by the use of a router, each router port that represents an interface is assigned an IP address that reflects the network it is connected to Figure 3 6 illustrates the connection of two networks via a router, indicating possible address assignments

7 A and C With PPP, each system could be required to authenticate itself This can be done using an authentication protocol The most common authentication protocols include the Password Authentication Protocol (PAP), the Challenge Handshake Authentication Protocol (CHAP), and the Microsoft adaptation of CHAP, MS-CHAP B and D are incorrect because domain authentication is used to validate a user, not the connection, and KPA does not exist 8 A Windows XP allows you to create a VPN server or RAS server that allows one connection You may create these servers through the New Connection Wizard B, C, and D are incorrect
