CompTIA Cloud+ (CV0-004) — Question 52

An e-commerce store is preparing for an annual holiday sale. Previously, this sale has increased the number of transactions between two and ten times the normal level of transactions. A cloud administrator wants to implement a process to scale the web server seamlessly. The goal is to automate changes only when necessary and with minimal cost.
Which of the following scaling approaches should the administrator use?

Answer options

• A. Scale horizontally with additional web servers to provide redundancy.
• B. Allow the load to trigger adjustments to the resources.
• C. When traffic increases, adjust the resources using the cloud portal.
• D. Schedule the environment to scale resources before the sale begins.

Correct answer: B

Explanation

Option B is correct because it allows for dynamic scaling based on real-time load, ensuring resources are adjusted only when needed, which helps maintain cost efficiency. Option A focuses on redundancy rather than just scaling based on need. Option C involves manual intervention which contradicts the goal of automation. Option D is preemptive and may lead to unnecessary costs if the expected traffic surge doesn't occur.
