• Flag

In which situation would the use of PAP be preferable to the use of CHAP?

• when router resources are limited

• when multilink PPP is used

• when a network administrator prefers it because of ease of configuration

• when plain text passwords are needed to simulate login at the remote host

Which protocol will terminate the PPP link after the exchange of data is complete?

• IPXCP

• NCP

• LCP

• IPCP

How much total bandwidth is provided by a T1 line?

• 64 kb/s

• 1.544 Mb/s

• 43.736 Mb/s

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?

• Set the DCE interface to a lower clock rate.

• Use the bandwidth command to increase the bandwidth of the link.

• Issue the command ppp quality 100.

• Issue the command ppp quality 70

Which two statements describe a PPP connection between two Cisco routers? (Choose two.)

• LCP test the quality of the link.

• LCP manages compression on the link.

• NCP terminates the link when data exchange is complete.

• With CHAP authentication, the routers exchange plain text passwords.

• Only a single NCP is allowed between the two routers.
