Question 211 of 267 from exam AZ-303: Microsoft Azure Architect Technologies
Question
HOTSPOT -
You have an Azure web app named App1 that has the following configurations:
-> The app runs on three instances.
-> The minimum number of instances is one.
-> The maximum number of instances is five.
You create the following autoscale rules for App1:
-> Decrease the instance count by one when the CPU percentage is less than 30.
-> Decrease the instance count by one when the memory percentage is less than 50.
-> Increase the instance count by one when the CPU percentage is greater than 80.
-> Increase the instance count by one when the memory percentage is greater than 75.
You expect App1 to be utilized as shown in the following table.
You need to identify the maximum number of instances that will be used by App1 during the expected periods of utilization.
What should you identify? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:
Explanations
On scale out, autoscale runs if any rule is met. On scale-in, autoscale requires all rules to be met. Therefore, the web app will scale out but will never scale back in because there is no time where the CPU is less than 30% AND the memory is less than 50%.
