LFCA Question #59: Real Exam Question with Answer & Explanation

Question

A team just developed a new feature on the company's main web application. An IT associate wants to test this new feature by making it available for only 10% of the users. If everything works without any problems for a week, the associate will then make it available for all users. Which release type should be used to achieve this goal?

Options

• ACanary release
• BExperimental release
• CAlpha release
• DBeta release

Explanation

The question describes a staged rollout strategy where a new feature is deployed to a small subset of users before a full release.

Common mistakes.

• B. An "experimental release" is a general term and not a specific, standardized release strategy for staged production deployment.
• C. An alpha release is typically an early, internal release for testing within the development team, not for a controlled rollout to a small percentage of external users.
• D. A beta release is a pre-release version made available to a wider group of external users (beta testers) for feedback and bug detection, but it usually implies a dedicated testing phase rather than a controlled, production-traffic rollout to a percentage of users.
