Refer to the exhibit. An engineer is designing a redistribution solution for a customer. The customer recently acquired another company and decided to Integrate the new network running RIPv1 with…

The correct answer is A. distribute-lists inbound under the EIGRP process denying RIPv1 learned prefixes. Using distribute-lists inbound under the EIGRP process, you can filter out the RIPv1 learned prefixes. This prevents the prefixes learned via RIPv1 from being redistributed back into EIGRP, thus avoiding potential routing loops during the redistribution process.
