CompTIA Cloud+ (CV0-003) — Question 229

A company is using a method of tests and upgrades in which a small set of end users are exposed to new services before the majority of other users. Which of the following deployment methods is being used?

Answer options

• A. Blue-green
• B. Canary
• C. Big bang
• D. Rolling

Correct answer: B

Explanation

The correct answer is B, Canary, as it specifically refers to releasing updates to a small subset of users to monitor performance and issues before a full rollout. The other options, such as Blue-green, involve parallel environments, Big bang suggests a simultaneous deployment across all users, and Rolling implies a gradual deployment without the specific targeting of a small user group.
