CompTIA Cloud+ (CV0-004) — Question 124

A company uses containers to implement a web application. The development team completed internal testing of a new feature and is ready to move the feature to the production environment. Which of the following deployment models would best meet the company’s needs while minimizing cost and targeting a specific subset of its users?

Answer options

• A. Canary
• B. Blue-green
• C. Rolling
• D. In-place

Correct answer: A

Explanation

The Canary deployment model allows for deploying a new feature to a small subset of users before a full rollout, reducing risk and cost. Blue-green and Rolling deployments may involve broader changes, which could be more expensive and less targeted. In-place deployment does not minimize risk effectively as it replaces the existing version without selective exposure.
