Discuss Splunk SPLK-4001 Exam Topic 2 Question 42

A Software Engineer is troubleshooting an issue with memory utilization in their application. They released a new canary version to production and now want to determine if the average memory usage is lower for requests with the 'canary' version dimension. They've already opened the graph of memory utilization for their service.

How does the engineer see if the new release lowered average memory utilization?

AOn the chart for plot A, select Add Analytics, then select MeanrTransformation. In the window that appears, select 'version' from the Group By field.

BOn the chart for plot A, scroll to the end and click Enter Function, then enter 'A/B-l'.

COn the chart for plot A, select Add Analytics, then select Mean:Aggregation. In the window that appears, select 'version' from the Group By field.

DOn the chart for plot A, click the Compare Means button. In the window that appears, type 'version1.

Suggested Answer: C

The correct answer is C. On the chart for plot A, select Add Analytics, then select Mean:Aggregation. In the window that appears, select 'version' from the Group By field.

This will create a new plot B that shows the average memory utilization for each version of the application. The engineer can then compare the values of plot B for the 'canary' and 'stable' versions to see if there is a significant difference.

Why would you use 'A/B-l'? That doesn't seem right.

Zona 10 months ago

I think 'Add Analytics' is the right way to go!

Hyun 10 months ago

Wait, is 'MeanrTransformation' even a thing? Sounds off.

Ricarda 10 months ago

Definitely agree with the 'version' grouping!

Latrice 11 months ago

Just select 'Mean:Aggregation' and group by 'version'.

Slyvia 11 months ago

I thought the Add Analytics option was key, but I’m torn between MeanrTransformation and Mean:Aggregation. They both sound familiar!

Paola 11 months ago

I feel like the Compare Means button might be the right choice here, but I’m not completely confident about how to set it up.

Ryann 11 months ago

I practiced a similar question where we had to group by a version, but I can't recall the exact steps for this one.

Sharee 12 months ago

I think I remember something about using analytics to compare different versions, but I'm not sure if it's MeanrTransformation or Mean:Aggregation.

Dino 12 months ago

I've got a good strategy here. I'll use option A to get the mean memory usage for each version, then I can compare them to see if the new canary version has lower average usage.

Talia 12 months ago

I'm a bit confused by the question. Do I need to do some kind of statistical analysis to compare the means? Option A seems to be the closest to what I'm thinking, but I'm not sure.

Filiberto 1 year ago

Okay, I think I've got this. I'll try option C and see if that gives me the mean memory usage for the different versions.

Arlene 1 year ago

Hmm, this looks like a tricky one. I'll need to think it through carefully.

Alpha 1 year ago

I think clicking the Compare Means button and typing 'version1' is the way to go to compare memory usage between versions.

Jesusita 1 year ago

Option C for the win! Gotta love that 'Group By' field - makes it easy to compare across versions.

Sylvia 1 year ago

Ha, 'A/B-l' sounds like some kind of hipster math equation. I'll stick with the more descriptive options.

Vonda 1 year ago

I believe selecting Mean:Aggregation for 'version' grouping will also provide insights on memory utilization.

Tawna 1 year ago

D could work, but it's not clear if 'version1' refers to the 'canary' version or something else. Better to be explicit with the version name.

Annett 1 year ago

I agree with Tawna, Mean Transformation will help determine if memory usage is lower for the 'canary' version.

Vashti 1 year ago

B looks interesting, but I'm not sure what 'A/B-l' means in this context. Might be a bit too cryptic for a production issue.

C) On the chart for plot A, select Add Analytics, then select Mean:Aggregation. In the window that appears, select 'version' from the Group By field.

Tawna 1 year ago

I think the engineer should select Add Analytics and Mean Transformation for version grouping.

Larue 1 year ago

Option C seems the most straightforward way to get the average memory usage for the 'canary' version. I like how it lets you group by the 'version' field.

Raylene 1 year ago

Yeah, that method makes it easy to see if the new canary version has lowered the average memory utilization.

Peggie 1 year ago

↳ replying to Larue

I agree, selecting Mean:Aggregation and grouping by 'version' seems like the most direct way to compare memory usage.

Roosevelt 1 year ago

I think option C is the best choice. It allows you to group by the 'version' field for average memory usage.
