AWS Certified Developer – Associate (DVA-C02) — Question 65

An engineer created an A/B test of a new feature on an Amazon CloudWatch Evidently project. The engineer configured two variations of the feature (Variation A and Variation B) for the test. The engineer wants to work exclusively with Variation A. The engineer needs to make updates so that Variation A is the only variation that appears when the engineer hits the application's endpoint.

Which solution will meet this requirement?

Answer options

• A. Add an override to the feature. Set the identifier of the override to the engineer's user ID. Set the variation to Variation A.
• B. Add an override to the feature. Set the identifier of the override to Variation A. Set the variation to 100%.
• C. Add an experiment to the project. Set the identifier of the experiment to Variation B. Set the variation to 0%.
• D. Add an experiment to the project. Set the identifier of the experiment to the AWS account's account ISet the variation to Variation A.

Correct answer: A

Explanation

The correct answer is A because adding an override with the engineer's user ID ensures that only Variation A will be shown when accessing the endpoint. Option B incorrectly uses Variation A as the identifier for the override, which does not achieve the desired outcome. Options C and D involve creating experiments that do not directly address the need to focus solely on Variation A.
