Huawei H12-831_V1.0 Exam - Topic 1 Question 84 Discussion

On the network shown in the figure, IS-IS runs on Rl, R2, R4, and R5, and the area ID is 49.0001. IS-IS runs on R3 and R6, and the area ID is 49.0002. In AS 65000, Ri, R3, R4, and R6 each establish IBGP peer relationships with R2 and R5. R2 and R5 are RRs, and Rl, R4, R3, and R6 are clients. The IBGP peer relationships are established using LoopbackO. The IP address of LoopbackO on each router is 10.0.X.X/32, and the router ID is 10.0.X.X, where X is the number of the router. Rl and R4 import the external route 192.168.1.0/24 to BGP through the import-route command, and R3 and R6 import the external route 192.168.2.0/24 to BGP through the import-route command. Which of the following statements are true?
A) For 192.168.2.0/24, R2 preferentially selects the BGP route received from R3. and B) For 192.168.1.0/24, R3 preferentially selects the BGP route received from R2. and C) For 192.168.2.0/24, R5 preferentially selects the BGP route received from R3. and D) For 192.168.1.0/24, R6 preferentially selects the BGP route received from R2.

I practiced a similar question where R5 selected routes based on the originating router, so I think R5 would prefer the route from R3 for 192.168.2.0/24.
