Discuss Splunk SPLK-2002 Exam Topic 13 Question 113

When implementing KV Store Collections in a search head cluster, which of the following considerations is true?

AThe KV Store Primary coordinates with the search head cluster captain when collection content changes.

BThe search head cluster captain is also the KV Store Primary when collection content changes.

CThe KV Store Collection will not allow for changes to content if there are more than 50 search heads in the cluster.

DEach search head in the cluster independently updates its KV store collection when collection content changes.

Suggested Answer: B

According to the Splunk documentation1, in a search head cluster, the KV Store Primary is the same node as the search head cluster captain. The KV Store Primary is responsible for coordinating the replication of KV Store data across the cluster members. When any node receives a write request, the KV Store delegates the write to the KV Store Primary. The KV Store keeps the reads local, however. This ensures that the KV Store data is consistent and available across the cluster.

Yeah, A is the way to go for sure!

Bulah 10 months ago

Wait, C sounds a bit off, is there really a limit like that?

Lang 10 months ago

I think B is misleading, they’re not the same.

Howard 10 months ago

D seems wrong, I thought they all synced up together.

Mable 11 months ago

A is definitely true, the primary coordinates with the captain.

Delfina 11 months ago

I feel like each search head updating its KV store independently sounds wrong, but I can't quite recall the details. Maybe it's option D?

Ezekiel 11 months ago

I vaguely recall that there are limits on how many search heads can be in a cluster, but I can't remember if it was 50 or something else.

Vesta 11 months ago

I think I practiced a question similar to this, and it mentioned that the KV Store Primary coordinates changes. So, I might lean towards A.

Cristal 11 months ago

I remember something about the KV Store Primary working with the search head captain, but I'm not sure if it's option A or B.

Avery 12 months ago

I'm not sure about the 50 search head limit in option C. That seems a bit specific, and I don't recall seeing that in the materials. I'll probably rule that one out and focus on the other options.

Azzie 12 months ago

Okay, let me think this through. I know that the KV Store Collection has to be managed across the search head cluster, so the coordination between the KV Store Primary and the cluster captain makes sense. I'll go with A.

Amber 12 months ago

Hmm, I'm a bit confused on this one. I'm not sure if the search head cluster captain is also the KV Store Primary when the collection content changes. I'll need to review that part again.

Ashanti 1 year ago

I'm pretty confident that the answer is A. The KV Store Primary coordinates with the search head cluster captain when the collection content changes.

Elza 1 year ago

Option A sounds the most logical to me. The KV Store Primary should be communicating with the search head cluster captain for changes.

Haha, I bet the exam writers came up with option C just to see if anyone would fall for it. Nice try, but I'm not biting!

Option C is just weird. Why would the number of search heads in the cluster affect the ability to update the KV Store collection? Doesn't make sense to me.

Glendora 1 year ago

Option D seems a bit off. I'm pretty sure the search heads don't update the KV Store independently. There has to be some coordination.

A) The KV Store Primary coordinates with the search head cluster captain when collection content changes.

Eve 1 year ago

I think D) is the correct answer because each search head should independently update its KV store collection.

Rodolfo 1 year ago

I'm not sure, but I think A) makes more sense because the KV Store Primary should be involved in coordinating changes.

Leatha 1 year ago

I disagree, I believe the answer is B) The search head cluster captain is also the KV Store Primary when collection content changes.

Kanisha 1 year ago

I think the answer is A) The KV Store Primary coordinates with the search head cluster captain when collection content changes.

Isidra 1 year ago

I think option B is the correct answer. The search head cluster captain is responsible for coordinating changes to the KV Store collection.

Definitely, having a centralized coordinator ensures consistency in the KV Store collection updates.

Staci 1 year ago

That makes sense. It's important for the captain to be in charge of coordinating changes.

I agree, option B is correct. The search head cluster captain is also the KV Store Primary when collection content changes.
