As shown in the network diagram, RTA and RTB are located in AS 1001, RTC, RTD, and RTE are located in AS 1002, and AS 1001 advertises the BGP route 11.11.11.0/24 to AS 1002. The main BGP configurations of RTC and RTD are as follows, if RTE 1. The RTC interconnection link is interrupted, and RTE accesses the 11.11.11.0/24 network segment, which WAN link should be preferred?

A . Prioritize WAN link 1, because MED 100 of RTC < MED 200 of RTD
B. Prioritize WAN link 1, because the eBGP route on RTC takes precedence.
C. Prioritize the WAN link 2, because MED 200 of RTD> MED 100 of RTC.
D. Prioritize the WAN link 2, because the eBGP route on RTD has priority.

Answer: D
