Actual exam question from Cisco's 642-883

Question #: 164
Topic #: 1

A service provider has set up new eBGP sessions for new customers who require Internet connectivity for their own public AS sessions. To connect, these sessions require MD5 authentication and no cluster ID configured. The NOC notified that one of these eBGP neighbors does not establish any session with the CE
BGP speaker. Which option is a potential cause if the BGP configuration is correct?

A. The BGPMD5 password has been typed incorrectly producing a failure in the authentication process.
B. A public AS does not require another service provider to connect to the Internet. The BGP configuration automatically blocks this type of design due to loop- avoidance built-in mechanisms.
C. The customer BGP speaker is receiving too many prefixes at once and no connection can be established without a maximum –prefix value configured.
D. No cluster ID is configured, so the BGP process does not find a way to identifythe service provider BGP speaker in the customer BGP route reflectors cluster- list. The session is not established to keep the customer iBGP core network loop-free.
