Exam 300-101 topic 2 question 560 discussion

Actual exam question from Cisco's 300-101

Question #: 560
Topic #: 2

Refer to the exhibit.

Looking at the topology diagram and the partial router configurations shown, which statement is true?

A. A routing loop will occur due to mutual route redistribution occurring on R1 and R2.
B. Suboptimal routing will occur due to mutual route redistribution occurring on R1 and R2.
C. Additional route filtering configurations using route maps and ACLs are required on the R1 and R2 routers to prevent routing loops.
D. R2 will not be able to redistribute the EIGRP subnets into OSPF, because R2 is missing the default seed metric for OSPF.

Suggested Answer: E. The 10.1.1.0/24 subnet will appear as 10.0.0.0/8 in the R5 routing table. 🗳️
Explanation -
RIPv1 is a classful routing protocol so the subnet 10.1.1.0/24 will be summarized to 10.0.0.0/8 in the R5 routing table. If we use RIPv2 on R1, R5 and use the no auto-summary command on R1 then the 10.1.1.0 subnet will appear in the routing table of R5. Notice that even if the auto-summary command is configured under router eigrp 1 of R1 but when redistributing into another routing protocol EIGRP still advertises the detailed network.
