Suggested Answer: B 🗳️
The command "ppp authentication chap pap" command indicates the CHAP authentication is used first. If it fails or is rejected by other side then uses PAP instead. If you want to use PAP first (then CHAP) you can use the "ppp authentication pap chap" command http://www.cisco.com/en/US/docs/ios/12_2/security/configuration/guide/scfathen.html
