AWS Certified Solutions Architect - ECR Events and Notifications Example Questions

Test your knowledge of ECR Events and Notifications

Question 1

Your team is developing an application that relies heavily on container images that are stored in Amazon ECR. The team would like to receive an Amazon SNS notification when new container images are pushed or existing images are updated. Which of the following services can help accomplish this?

Correct Answer: Amazon EventBridge

Using Amazon EventBridge, you can set up an event rule targeting Amazon SNS whenever new container images are pushed or existing images are updated in Amazon ECR. EventBridge supports a variety of AWS services and SaaS applications as event sources, making it the ideal choice for this scenario. The other options listed do not provide the same level of integration for this specific use case.

Question 2

Your team has discovered that several old and unused container images are stored on ECR. They want to set up an automatic cleanup based on a lifecycle policy. Which property should be configured to set the rule status and avoid image deletion if the rule is not finalized?

Correct Answer: ruleStatus

When defining a lifecycle policy rule, you must specify the 'ruleStatus' property to indicate whether the rule is enabled ('Enabled') or disabled ('Disabled'). This allows you to finalize the rule before it starts deleting images. The other options, 'status', 'ruleAction', 'ruleStatusActivated', 'ruleState', and 'ruleCondition', do not exist or are not applicable in this scenario.

Question 3

A development team needs to automatically scan their images upon being pushed to an Amazon ECR repository. How can you enable this feature?

Correct Answer: Enable image scanning in the ECR repository settings

To enable image scanning in Amazon ECR, you need to modify the repository settings and enable image scanning. This will automatically trigger image scans upon being pushed to the ECR repository. The remaining options do not enable this feature; they either have no relation to image scanning or serve different purposes.
