Amazon CLF-C02 Exam - Topic 2 Question 39 Discussion

Actual exam question for Amazon's CLF-C02 exam
Question #: 39
Topic #: 2
[All CLF-C02 Questions]

A company needs to invoke an AWS Step Functions workflow each time an Amazon EC2 instance state changes to RUNNING.

Which AWS service can the company use to meet this requirement?

Show Suggested Answer Hide Answer
Suggested Answer: C

Amazon EventBridge Overview:

EventBridge is a serverless event bus that enables applications to react to changes in AWS resources.

It supports routing events such as EC2 state changes to various targets, including AWS Step Functions.

How EventBridge Meets the Requirement:

EventBridge can capture the EC2 instance state change event and trigger the execution of a Step Functions workflow.

The integration is seamless and supports workflows triggered by multiple event sources.

Why Other Options Are Incorrect:

A . Amazon SageMaker: Used for building, training, and deploying machine learning models; not related to event triggers.

B . Amazon Connect: A cloud-based contact center service; unrelated to event triggers.

D . AWS Fargate: A compute engine for containers; does not manage events or invoke workflows.

I thought AWS Fargate might be an option too, but I guess not.

I vaguely recall a practice question about triggering workflows with state changes, and EventBridge was mentioned. It makes sense for this scenario.

I feel like SageMaker and Connect are not related to EC2 instance states. I think EventBridge is the best option, but I need to double-check.

I'm not entirely sure, but I remember something about using CloudWatch Events for EC2 state changes. Is EventBridge the same thing?

I think we discussed EventBridge in class as a way to respond to state changes in AWS resources. It seems like the right choice here.

I'm feeling pretty confident about this one. The question is clearly asking about an event-driven integration, and Amazon EventBridge is the AWS service designed for that exact purpose. Connecting EC2 state changes to a Step Functions workflow is a classic use case for EventBridge.

Okay, I've got it. The answer has to be Amazon EventBridge. It's the AWS event bus service that can capture the EC2 instance state change event and then route it to trigger the Step Functions workflow. Feels like a pretty straightforward application of EventBridge.

Hmm, not sure about this one. I'm a bit confused - is Amazon SageMaker the right choice here? That's more for machine learning, right? I'll have to think this through carefully.

This looks like it's asking about AWS services that can trigger a Step Functions workflow. I think the key is to focus on the event-driven nature of the requirement - we need a service that can detect the EC2 instance state change and then kick off the workflow.
