CompTIA Cloud+ (CV0-004) — Question 50

A cloud solution needs to be replaced without interruptions. The replacement process can be completed in phases, but the cost should be kept as low as possible. Which of the following is the best strategy to implement?

Answer options

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

Correct answer: B

Explanation

The Rolling strategy allows for gradual updates to the cloud solution, minimizing costs and preventing service interruptions by updating a few instances at a time. Blue-green and Canary might involve more resources and complexity, while In-place does not facilitate phased replacement effectively.
