Discuss Splunk SPLK-4001 Exam Topic 7 Question 25

A customer has a very dynamic infrastructure. During every deployment, all existing instances are destroyed, and new ones are created Given this deployment model, how should a detector be created that will not send false notifications of instances being down?

ACreate the detector. Select Alert settings, then select Auto-Clear Alerts and enter an appropriate time period.

BCreate the detector. Select Alert settings, then select Ephemeral Infrastructure and enter the expected lifetime of an instance.

CCheck the Dynamic checkbox when creating the detector.

DCheck the Ephemeral checkbox when creating the detector.

Suggested Answer: D

The correct answer is D. The detector is automatically linked to the chart.

When you create a detector from a chart on a custom dashboard, the detector is automatically linked to the chart. This means that you can see the detector status and alerts on the chart, and you can access the detector settings from the chart menu. You can also unlink the detector from the chart if you want to1

Changes made to the chart do not affect the detector, and changes made to the detector do not affect the chart. The detector and the chart are independent entities that have their own settings and parameters. However, if you change the metric or dimension of the chart, you might lose the link to the detector1

The alerts generated by the detector will show up in the Alerts page, where you can view, manage, and acknowledge them. You can also see them on the team landing page if you assign the detector to a team2

To learn more about how to create and link detectors from charts on custom dashboards, you can refer to this documentation1.

Definitely not A, auto-clear could lead to missed issues.

Vivienne 11 months ago

Wait, can we really just check a box for dynamic? Sounds too easy.

Lewis 11 months ago

A is a solid choice too, but might still trigger false alerts.

Heike 11 months ago

I think D is the way to go, makes sense for ephemeral setups!

Rolande 11 months ago

Option B seems right, gotta account for instance lifespan.

Michel 12 months ago

I’m leaning towards option D, but I’m a bit confused about the difference between "Dynamic" and "Ephemeral" in this context.

Yuriko 12 months ago

I feel like I saw a question about dynamic checkboxes before, but I can't recall if it was related to this kind of deployment model.

Nathalie 12 months ago

I think option B sounds familiar, especially with the expected lifetime of instances. That might help avoid false alerts.

Lili 1 year ago

I remember something about ephemeral infrastructure from our practice questions, but I'm not sure if it was specifically about alert settings.

Fernanda 1 year ago

Hmm, this is a good one. I'm leaning towards option B, selecting Ephemeral Infrastructure and entering the expected instance lifetime. That seems like it would handle the dynamic deployment model well.

Yuette 1 year ago

I'm a bit confused on the difference between the Ephemeral Infrastructure and Dynamic options. I'll need to review those settings carefully to make sure I select the right one.

Arthur 1 year ago

Okay, I think I've got this. The key is to use the Auto-Clear Alerts feature and set an appropriate time period to clear alerts when instances are destroyed and new ones created.

Staci 1 year ago

This seems like a tricky question. I'll need to think carefully about the deployment model and how to set up the detector to avoid false notifications.

Tom 1 year ago

The question is pretty straightforward. I'd go with option A - create the detector, select Auto-Clear Alerts, and set the time period accordingly. That should do the trick.

Major 1 year ago

Okay, I see a few clear benefits like cost reductions and increased online revenues. But I'm not sure about some of the other options - I'll have to analyze them more closely.

Emogene 1 year ago

Options C and D seem confusing because they mention hubs and switches, but I thought they weren't necessary for a wireless setup.

Jose 1 year ago

Option B is the way to do it. I mean, who doesn't love a little 'ephemeral' action in their infrastructure? Keeps things spicy, ya know?

User 3: I agree, it adds a nice touch of dynamism to the whole setup.

User 1: Option B is definitely the way to go. Ephemeral infrastructure is the key.

Tula 1 year ago

Ah, I see. Option B is the correct answer. Gotta love those dynamic infrastructures, eh? Keeps us on our toes!

User 4: Creating the detector with the right settings is key in this scenario.

User 3: I agree, it's important to consider the expected lifetime of an instance.

User 1: Option B is the correct answer.

Robt 1 year ago

I'm not sure if Option C or D are the right choices. The question specifically mentions 'false notifications of instances being down', so I think the auto-clear alerts or ephemeral infrastructure settings are the way to go.

Therese 1 year ago

B) Create the detector. Select Alert settings, then select Ephemeral Infrastructure and enter the expected lifetime of an instance.

Leigha 1 year ago

A) Create the detector. Select Alert settings, then select Auto-Clear Alerts and enter an appropriate time period.

Trinidad 2 years ago

Option B seems like the way to go. Selecting the Ephemeral Infrastructure option and entering the expected lifetime of an instance should handle the dynamic nature of the infrastructure.

Leatha 1 year ago

↳ replying to Trinidad

User 4: Yeah, setting an appropriate time period for auto-clearing alerts could prevent unnecessary notifications.

Reta 1 year ago

↳ replying to Trinidad

User 3: I think selecting Auto-Clear Alerts could also help in this situation.

Agustin 1 year ago

↳ replying to Trinidad

User 2: I agree. That sounds like the best approach to avoid false notifications.

User 1: Option B seems like the way to go. Selecting the Ephemeral Infrastructure option and entering the expected lifetime of an instance should handle the dynamic nature of the infrastructure.

Chun 2 years ago

I'm not sure. Maybe we should also consider selecting Ephemeral Infrastructure to account for the dynamic nature of the infrastructure.

Dorothy 2 years ago

I agree with Azalee. That way we can avoid false notifications during deployments.

Azalee 2 years ago

I think we should create the detector and select Auto-Clear Alerts.
