Show Suggested Answer Hide Answer
Suggested Answer: D

BGP policy framework is a set of tools that allows you to control the flow of routing information and apply routing policies based on various criteria. BGP policy framework consists of several components, such as route maps, prefix lists, community lists, AS path lists, and route filters. Route maps are used to define routing policies by matching certain conditions and applying certain actions. Prefix lists are used to filter routes based on their prefixes. Community lists are used to filter routes based on their community attributes. AS path lists are used to filter routes based on their AS path attributes.Route filters are used to filter routes based on their prefix length or range3. In this question, we have a route map named ISP-A that has two clauses: clause 10 and clause 20. Clause 10 matches any route with a prefix length between 8 and 24 bits and sets the local preference to 200. Clause 20 matches any route with a prefix of 224.7.7.7/32 and rejects it. The route map is applied inbound on the BGP neighborship with ISP-A. Based on this configuration, the correct statement is that joins for group 224.7.7.7 are always rejected, regardless of the group count. This is because clause 20 explicitly denies any route with a prefix of 224.7.7.7/32, which corresponds to the multicast group 224.7.7.7.

IGMPv2 interface. Source address will never match as wild card. Only reject groups that exceed the maximum group limit of 25. Answer is D. If was IGMPv3 interface, different.

Ah, the joys of IGMP snooping. At least the exhibit is clear enough to make a choice. I'm going with D.

I think Charlene is right, the group count value is the key factor here. So, D) makes more sense to me

D seems like the way to go. Who needs to count groups when you can just reject everything? #LazyNetworkAdmin

True, finding a balance between security and functionality is key in network administration.

But what if there are legitimate groups that need to join? Maybe a balance is needed.

I agree, rejecting everything seems like the lazy but effective approach.

Lazy network admin for sure, but it gets the job done.

I disagree, I believe the correct answer is D) Joins for group 224.7.7.7 are accepted if the group count is less than 25

Hmm, this is a tricky one. I'm leaning towards C, but I'll double-check the details just to be sure.

I'm not sure about this one. The configuration looks a bit complex, but I'll go with option D just to be safe.
