CompTIA Cloud+ (CV0-003) — Question 43

A company wants to utilize its private cloud for a new application. The private cloud resources can meet 75% of the application's resource requirements. Which of the following scaling techniques can the cloud administrator implement to accommodate 100% of the application's requirements?

Answer options

• A. Horizontal
• B. Vertical
• C. Cloud bursting
• D. Autoscaling

Correct answer: B

Explanation

The correct answer is B, Vertical scaling, which involves adding more resources to the existing server to meet the application's full requirements. Horizontal scaling (A) adds more servers, which may not help if the existing server is already at capacity. Cloud bursting (C) allows for temporary resource usage outside the cloud, but it doesn't resolve the need for complete resource availability within the private cloud. Autoscaling (D) automatically adjusts resources based on demand but is not suitable if the private cloud is already limited to 75% of the required capacity.
