CCIE Written Bootcamp Update ~ CCNP, CCSP and CCIE Security Version 4 Training Institute in India- Delhi

Hello everyone!
I am updating Practice Exam 2 (In Progress) for the CCIE Written Exam Bootcamp in your Members’s Site. I will be adding questions over the next couple of weeks. Currently, you will find some new Multicast Addressing/IGMP/MLD questions in there for your entertainment.
I am focusing on Practice Exam 2 right now for two main reasons. 1) It is allowing me to address some deficiencies with Practice Exam 1 and the lectures, and 2) More and more students are using this bootcamp as a prep tool for the dreaded Core Knowledge section.
Let us examine one of the new questions and walk through my solution logic.
Q. How does a router respond after receiving an IGMP Leave Group message?
a. The router does nothing
b. The router responds with a Membership Report
c. The router responds with a Group Specific Query
d. The router responds with a General Query

Hmmm, OK, I do not remember this right off, but let me see if I can reason through the answer. The IGMP Leave Group message, yes…this excellent IGMP Version 2 invention was designed to help with “Leave Latency” in Multicast. This is the issue where a receiver silently goes away and the poor router does not know this and keeps sending multicast frames out an interface for no reason whatsoever.
So, let me see what makes the best sense here. Would the router do nothing (option a)? No, that does not seem like a good use of technology.
Does the router respond with a Membership Report? Hmmm, I think it is the hosts that use Membership Reports to signal their participation in the multicast group.
Does the router respond with a Group Specific Query? Now that seems to make a lot of sense. Query the segment’s specific multicast group to see if there is anyone left in the segment that wants the multicast feed. I really like this response, but let me check the final option….
Does the router respond with a General Query? Well, this might work, but it seems like option C makes a lot more sense for the whole IGMP process.
I am going with Option C as my final answer! Too bad I cannot phone a friend (Petr Lapukhov)…
Enjoy the new questions everyone!

About Network Bulls Gurgaon

Which is best ccsp institute in delhi? cisco certified security professional training in delhi ncr gurgaon. Nb provides world class top training for cisco security firewall in delhi ncr. Cisco CCIE certification exam lab asia's biggest lab training institution in new delhi gurgaon india. There are many institutes in India, who claims to provide Job Guarantee after CCNA even. There are some small institutes, who make fool of students with there cheap tricks and frauds. Some institutes in this field, do not have CCIE Certified trainers and racks available, but they claim to provide best training from other big institutes. Student should not take admission in such fraud and cheap institutes. Students can also give their valuable feedback, complaints and reviews about different institutes in our forums. But students should also be aware of wrong and unauthenticated feedback or complaints against great institutes like Network Bulls, Networkers Home and INE in some fake complaint forums, where no one is authenticating any comment or posts. Those wrong posts are written by some competitor institutes only. Those cheap and fraud institutes can't earn money and get admissions based on their results and infrastructure. They just write rubbish and wrong things on different forums against some good institutes and try to get admissions. A student who want to get refunds or good training or want to give feedback, can also go to consumer court and register a complaint against that fraud institute.
As per my experience Network Bulls and INE are both the best institutes of world.
