CompTIA Cloud+ (CV0-004) — Question 110

A cloud engineer is implementing a deployment strategy with the following requirements:

• At least two environments for production and development must be supported.
• Changes in one environment must not impact the other environment.
• The highest possible availability must be achieved.

Which of the following deployment strategies should the engineer implement?

Answer options

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

Correct answer: B

Explanation

The Blue-green deployment strategy is the best choice as it allows for two separate environments where one can be live while the other is idle, preventing changes in one from affecting the other. Rolling, In-place, and Canary strategies do not provide the same level of environment isolation or availability, as they typically involve updates to the live environment, which can impact service. Thus, Blue-green ensures the highest availability and minimal risk during deployments.
