Microsoft Azure Architect Technologies (2020, legacy) — Question 44

You have an Azure web app named App1 that is configured to run between two and five instances. There are currently three instances of App1 running.
App1 has the following autoscale rules:
Increase the instance count by one when the CPU percentage is greater or equal to 80.
Decrease the instance count by one when the CPU percentage is less than or equal to 60.
You are evaluating the following CPU percentage of utilization for App1:
✑ 60%
✑ 55%
✑ 50%
✑ 45%
You need to identify which utilizations will cause App1 to scale in.

Answer options

• A. 45% only
• B. 45% and 50% only
• C. 50% and 55% only
• D. 45%, 50%, and 55% only

Correct answer: D

Explanation

The correct answer is D because any CPU utilization at or below 60% will activate the scale-in rule. Since 60%, 55%, and 50% are all at or below this threshold, they will all cause App1 to scale in. Options A, B, and C do not account for all the relevant utilization percentages that meet the scaling criteria.
