NEW QUESTION # 114 
Refer to the exhibit. An architect must design a solution to connect the network behind R3 with the EIGRP network. Which mechanism should be included to avoid routing loops?
Answer: B
Explanation:
Route tags are the correct loop-prevention mechanism when connecting another routing domain or redistributed network behind R3 into an EIGRP network. Redistribution can create route feedback: a route learned from one domain is redistributed into another, then later redistributed back into the original domain as if it were new information. That can produce routing loops or suboptimal path selection, especially in multipoint redistribution designs. Cisco route-map based redistribution commonly uses route tags to mark the origin of redistributed routes. Other redistribution points can then match those tags and prevent the same routes from being reintroduced into the source domain. Split horizon prevents advertisements back out the interface on which a route was learned, but it is not sufficient for multipoint redistribution loop prevention.
Summarization reduces route detail and query scope but does not identify route origin. The OSPF down bit is used in MPLS VPN/OSPF PE-CE scenarios, not general EIGRP redistribution. Therefore, the design should use route tags. Reference topics: EIGRP redistribution, route tagging, routing-loop prevention, route maps, redistribution policy.
NEW QUESTION # 115
Which type of rendezvous point deployment is standards-based and supports dynamic RP discovery?
Answer: D
Explanation:
Bootstrap Router is the standards-based mechanism that supports dynamic RP discovery in a PIM sparse- mode domain. Cisco documentation distinguishes Auto-RP, which is Cisco-proprietary, from BSR, which is defined for standards-based RP distribution. With BSR, candidate RPs advertise their availability, and the elected bootstrap router distributes RP-set information throughout the PIM domain. This removes the operational burden of manually configuring the same static RP information on every multicast router. Anycast- RP provides RP redundancy and load sharing but does not by itself provide standards-based dynamic RP discovery across the domain. Static RP is simple but not dynamic. Auto-RP can dynamically distribute RP information, but it is not the standards-based answer. The design value of BSR is most visible in large multicast domains, where routers need consistent RP information and manual changes are risky. Therefore, when the question asks for a standards-based RP deployment that supports dynamic RP discovery, the correct answer is bootstrap router. Reference topics: PIM sparse mode, Bootstrap Router, candidate RP, RP-set distribution, dynamic RP discovery.
