9. Question
Refer to the exhibit. A network administrator is configuring the PPP link between the two routers. However, the PPP link cannot be established. Based on the partial output of the show running-config command, what is the cause of the problem?

CCNA4 v6.0 Chapter 2 Exam 002
- The usernames do not match.
- The passwords do not match.
- The passwords should be longer than 8 characters.
- The interface IP addresses are in different subnets.
10. Question
Which is an advantage of using PPP on a serial link instead of HDLC?
- option for authentication
- higher speed transmission
- fixed-size frames
- option for session establishment
11. Question
Which protocol will terminate the PPP link after the exchange of data is complete?
- NCP
- LCP
- IPCP
- IPXCP
12. Question
Which serial 0/0/0 interface state will be shown if no serial cable is attached to the router, but everything else has been correctly configured and turned on?
- Serial 0/0/0 is up, line protocol is up
- Serial 0/0/0 is up, line protocol is down
- Serial 0/0/0 is down, line protocol is down
- Serial 0/0/0 is up (looped)
- Serial 0/0/0 is up (disabled)
- Serial 0/0/0 is administratively down, line protocol is down
13. Question
How much total bandwidth is provided by a T1 line?
- 1.544 Mb/s
- 64 kb/s
- 128 b/s
- 43.736 Mb/s
14. Question
A network engineer is monitoring an essential, but poor quality, PPP WAN link that periodically shuts down. An examination of the interface configurations shows that the ppp quality 90 command has been issued. What action could the engineer take to reduce the frequency with which the link shuts down?
- Issue the command ppp quality 70.
- Issue the command ppp quality 100.
- Set the DCE interface to a lower clock rate.
- Use the bandwidth command to increase the bandwidth of the link.
15. Question
A network engineer is troubleshooting the loss of MPEG video viewing quality as MPEG video files cross a PPP WAN link. What could be causing this loss of quality?
- PAP authentication was misconfigured on the link interfaces.
- The clock rates configured on each serial interface do not match.
- Link Quality Monitoring was not configured correctly on each interface.
- The compress command was used when PPP was configured on the interfaces.
16. Question
Which PPP option can detect links that are in a looped-back condition?
- Magic Number
- MRU
- Callback
- ACCM
17. Question
A network engineer has issued the show interfaces serial 0/0/0 command on a router to examine the open NCPs on a PPP link to another router. The command output displays that the encapsulation is PPP and that the LCP is open. However, the IPV6CP NCP is not shown as open. What does the engineer need to configure to open the IPV6CP NCP on the link?
- Configure CHAP authentication on each router.
- Configure PPP multilink interfaces on each router.
- Configure an IPv6 address on each interface on the link.
- Issue the compress predictor command on each interface on the link.
18. Question
Which three physical layer interfaces support PPP? (Choose three.)
- FastEthernet
- GigabitEthernet
- Ethernet
- Ethernet
- synchronous serial
- HSSI
19. Question
What are three components of PPP? (Choose three.)
- authorization
- LCP
- parallel communications
- NCP
- support for LAN and WAN

20. Question
Refer to the exhibit. What type of Layer 2 encapsulation will be used for connection D on the basis of this configuration on a newly installed router:

RtrA(config)# interface serial0/0/0
RtrA(config-if)# ip address 128.107.0.2 255.255.255.252
RtrA(config-if)# no shutdown
