6 as Minimum number of instance

the answer is Zero (C)

B. min 6

B. Six If as a result of executed a scaling rule, the number of ECS instances in a scaling group is less than the minimum size value or greater than the maximum size value of instances allowed for the group, auto-scaling will automatically adjust the number of instances to be added or removed, so that the minimum or maximum instance values cannot be exceeded.

Should be 6. 6 is the minimum instance

should be 6 as minimum instance can be run is equal to 6

For example, let's say a scaling group is created and it's set to a maximum instance count of three ECS instances, and a minimum count of two and let's say that currently there are two ECS instances in the group and a scaling rule is added to add three more instances, well in this case, auto-scaling only adds one instance. This automatic adjustment stops the maximum instance count being exceeded and likewise, if the group now contains three instances and we have a scaling rule that is going to remove five instances, there are only three instances in the groups, so we can't possibly remove five and if we were to remove all three of those instances, then the size of the group would be zero, which is less than, in this scenario, the minimum size of two. https://cloudacademy.com/course/alibaba-auto-scaling-1247/scaling-rules/

6 as Minimum number of instance

why not 5 left

Max is 8, already have 8. Absolutely is Zero - C
