Microsoft Azure Architect Design (2020, legacy) — Question 36

You need to recommend a strategy for the web tier of WebApp1. The solution must minimize costs.
What should you recommend?

Answer options

• A. Configure the Scale Up settings for a web app.
• B. Deploy a virtual machine scale set that scales out on a 75 percent CPU threshold.
• C. Create a runbook that resizes virtual machines automatically to a smaller size outside of business hours.
• D. Configure the Scale Out settings for a web app.

Correct answer: D

Explanation

The correct answer is D because configuring Scale Out settings allows for dynamic scaling based on demand, which helps to optimize costs by only using resources when necessary. Option A is incorrect as scaling up typically involves higher costs due to larger resources, while option B could lead to unnecessary expenses if the VM scale set is not managed properly. Option C, while cost-effective, does not address immediate scaling needs during business hours.
