why is it 1 on the second question, it decreases by 1 when CPU utilization goes below 25%, but there is no rule for when to count down again and so on ? it only exist for the scale out rule.

The scale in rule applies each 10 minutes. it decreases VM count by 1, meaning -6 in 60 minutes. We can't have -1 VMs and we can't have 0 either, because the minimum is 1.

There must be duration otherwise it will not scale in properly , example , if it does not consider the duration for scale in , it will never go less than 4 vms that's why I agree Box 2 should be 2 we should consider scale out duration for scale in too

I agree with you because it did not say when the duration for countdown starts..and by the way, the question states there are 5 instances to start with. We must not assume what these questions are asking of us. go with the strict and stated meaning of the question. i say 3 for box1 and 4 for box2. please somebody correct if a am wrong.

wouldnt it scale in every 10 minutes and decrease count by 1 unit. From 10am to 11am there are 6 x 10 min slots. Each time it scales in, it will bring the count down by 1 until it reaches minimum which is 1?

Box-1 : 3 Initial starts 2 VM's 15 minutes have passed. at 10 minutes 1 VM was added we now have 3 VM's. Cool down is 5 Minutes before another 10 minute wait cycle starts so the answer is 3. Box-2: 1 Initial 5 VM's 60 minutes Pass. 1 VM removed every 15 minute cycle. 10 minutes wait timer plus 5 minute cool down equals 15 minutes cycle. Four 15 minute cycles pass equaling 60 minutes removing 4 VM's. We have 1 VM left. Default Scale in and Out Default Durations are 10 minutes with 5 minute cool down. The default scale set settings in Azure are: -Minimum number of instances 1 -Maximum number of instances 10 -Scale out CPU threshold (%) 75 -Duration in minutes10 -Number of instances to increase by 1 -Scale in CPU threshold (%) 25 -Number of instances to decrease by -1 https://learn.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-autoscale-portal#create-a-rule-to-automatically-scale-in

unfortunately these questions are poorly formulated. Why do you assume that at the 9:00 the count is 2? there is no mention about the cpu usage before 9:00, and moreover this is a custom policy, how do you know that the cooldown time is 5 minutes (i know that it's the default time). I hate the lack of context in these questions

The autoscale job runs every 30 to 60 seconds, depending on the resource type. Until 9:10 AM, rules can't apply because granularity period not reached. At 9:10 AM, count=3. It quickly jumps up every minute to max value in drop-down which is 5. Between 10-11 AM, the count starts dropping from 5 to 1. So Box-1: 5, Box-2: 1

Answers are box-1 : 3 and box-2: 1 for the second choice without any countdown duration, the default is 10 mins, so it will reach the minimum of VM.

this is incorrect as it drops one VM per 15mins. Even though its start on 5VMs after 60 minutes it drops to 1VM. 60/15=4. 5-4=1

minimum VMs are 2 after 15 minutes 2 other should be added so it will be 4 i dont know why it says 3????!!!

Because it scales up by one after 10 minutes. So after 10 minutes 1 is added, but it won't add another for another 10 minutes and only 5 more minutes have passed, so the answer is 3.

Impossible to answer box-2, because we don't know the duration and cool down for scale in...

The answer for box-2 is 1. After creating a scale set, go the the resource, click Scaling under Settings and open the scale in rule. You will find Duration(minutes) is defaulted to 5. I tested this scenario just to check the default duration because at the time of creating the VMSS on the portal you don't get an option to choose duration for Scal in.

I think you are mistaking the initial instance count (which is 2) as the minimum (which is the number of VMs to add when the threshold is crossed).

Agree, since it says that the scale set starts at 9:00, it means it starts with 2 instances.
