May 14th, 2010 by admin.

1.

Refer to the exhibit. Which statement is true about PPP operation? Layer 2 is down. LCP, IPCP, and CDPCP negotiations are in progress. Only the link-establishment phase completed successfully. Both the link-establishment and network-layer phase completed successfully.

2. What does the demarcation point represent in data communication physical circuits?

DTE/DCE interface on the device connecting to the Internet location of the firewall or router physical point at which the public network ends and the private customer network begins tag assigned to the physical block where a cross-connect occurs 3. It monitors the link for congestion and dynamically adjusts the acceptable window size. It uses MD5 encryption while negotiating link establishment parameters.) The router has agreed on IP parameters.) It is responsible for negotiating link establishment. Which two statements are true regarding the output shown? (Choose two. Which three statements are true regarding LCP? (Choose three. The router is negotiating IP compression options. It negotiates options for Layer 3 protocols running over PPP. The router has negotiated LCP successfully. Refer to the exhibit. 5. It terminates the link upon user request or the expiration of an inactivity timer. . It can test the link to determine if link quality is sufficient to bring up the link. What function do Network Control Protocols provide for a PPP connection? to supply error detection to establish and terminate data links to provide authentication capabilities to PPP to manage network congestion and to allow quality testing of the link to allow multiple Layer 3 protocols to operate over the same physical link 4.

6. Which two options can LCP negotiate? (Choose two. Which three statements are correct about HDLC encapsulation? (Choose three.) HDLC does not support CDP.The router is requesting an IP address from its peer. On the basis of the show interface Serial0/0 output. Refer to the exhibit. .) link quality authentication dynamic flow control compression and network layer address for IP connection-oriented or connectionless communication methods 8. The router has accepted IP but not the suggested IP options. how many NCP sessions have been established? one two three four 7.

35 10. Refer to the exhibit. Which serial communications DTE/DCE interface standard is used to provide highspeed connectivity of up to 52 Mbps between LANs and is found on many high-end Cisco routers? EIA/TIA 232 (RS-232) EIA/TIA 422 (RS-422) EIA/TIA 423 (RS-423) EIA/TIA-612/613 (HSSI) ITU V.HDLC and PPP are compatible. 9. HDLC is the default serial interface encapsulation on Cisco routers. Which PPP configuration option can be used to establish load balancing over the interfaces of a router? callback multilink compression error detection 11. HDLC supports PAP and CHAP authentication. HDLC implementation in Cisco routers is proprietary. HDLC uses frame delimiters to mark the beginnings and ends of frames. What can be concluded about the function of the Serial 0/0/0 interface on the router after the commands are entered? .

the DTE device. 12.3 255. the DCE device. to communicate over its serial 0/0/0 interface to router R1? Router(config)# hostname R3 R3(config)# username R1 password Cisco R3(config)# interface Serial 0/0/0 R3(config-if)# encapsulation ppp R3(config-if)# ip address 172.3 255.255.255. Router R1.16. has just been configured for PPP encapsulation with authentication.0 R3(config-if)# ppp authentication chap Router(config)# hostname R3 R3(config)# username R3 password Cisco R3(config)# interface Serial 0/0/0 R3(config-if)# encapsulation ppp R3(config-if)# ip address 172.16.3.3. What series of commands will allow another router.All username and password information that is sent will be encrypted. All authentication on the serial link will be accomplished using a two-way handshake.0 Router config-if)# ppp authentication chap Router (config)# username R1 password Cisco Router config)# interface Serial 0/0/0 Router (config-if)# clockrate 64000 Router config-if)# encapsulation ppp Router (config-if)# ip address 172.16.255.1 255.0 R3(config-if)# ppp authentication chap Router (config)# username Router password Cisco Router (config)# interface Serial 0/0/0 Router (config-if)# clockrate 64000 Router (config-if)# encapsulation ppp Router (config-if)# ip address 172. The serial link will be closed if the number of received packets at the destination node falls below 90 percent of the packets that are sent.255.3.1 255.16. The Predictor algorithm will be used to compress all packets that are sent and received on the serial link.255.0 Router (config-if)# ppp authentication chap . Refer to the exhibit.3.255.255.255.

CHAP uses a 2-way handshake to establish a link. Which three statements correctly describe PPP authentication? (Choose three. Parallel connections are subject to excessive attenuation. 15. Parallel connections are subject to clock skew and to crosstalk between wires. CHAP uses repeated challenges for verification. PAP uses a 3-way handshake to establish a link. . Which authentication protocol can be spoofed to allow playback attacks? MD5 CHAP PAP NCP 16.) PAP sends passwords in clear text. Why are serial connections preferred over parallel connections for long transmission lengths? Parallel connections do not support error checking. Parallel connections transmit over only two wires and therefore transmit data more slowly. 14. CHAP uses a challenge/response that is based on the MD5 hash algorithm. PAP provides protection from repeated trial-and-error attacks.13.

. One router has suggested PAP authentication. 18. Refer to the exhibit. A timing problem has occurred on the cable. What statement is true regarding the output shown? NCP has successfully negotiated. so the routers are trying CHAP authentication. If the interface is in DCE mode. While troubleshooting a serial interface. a technician enters the command show interface serial 0/0/0 .) TDM relies on Layer 3 protocols to operate. and the other has accepted authentication but suggested CHAP authentication. The router configuration contains the shutdown interface configuration command.) The remote CSU or DSU has failed. what two problems are likely to cause the indicated problem? (Choose two. The line is not physically connected to the CSU/DSU. Which two statements are true about time-division multiplexing (TDM)? (Choose two. The PAP passwords did not match. The router is not sensing a CD signal. One router can only use PAP authentication while the other router can only use CHAP. 17. so the connection has been rejected.efer to the exhibit.

What is the reason for this? Interface Serial0/0/0 resets very frequently. Refer to the exhibit. Router R1 is not able to communicate with a neighbor router that is directly connected to serial 0/0/0. The interface has been administratively shutdown with the shutdown command.Multiple channels can transmit over a single link. It allows information from multiple channels to be allocated bandwidth on multiple wires. Original data streams must be reconstructed at the destination. 19. What advantage does PPP have over HDLC for serial communications? . TDM methods vary depending on the Layer 2 protocol that is used. PPP LQM has shutdown the serial interface. The serial interface has no input or output queues available. The serial interface is not configured for a Layer 2 protocol. 20.
