B.The automated scaling is primarily used to improve service uptime and availability
C.The automated scaling is primarily used to save costs by matching the number of running VMs to user demand.
D.The automated scaling is primarily used to identify the common possible issues in the current configuration.

Correct Answer: C 
The scaling tool offers a low-cost automation solution for customers who are looking towards optimizing their session host VM costs. Automated scaling is used to provision and de-provision VMs to save costs depending upon the user demands or usage patterns. This automation can be based on a schedule to match common business hours or actual resource utilization.
Option A is incorrect.Automated scaling is used for provisioning and de-provisioning VMs to save costs depending upon the usage patterns or user demands. Vertically scaling VM size is possible but it is not the main reason for autoscaling.
Option B is incorrect. VM availability sets are used to help ensure service uptime and availability.
Option C is correct. Automated scaling is used to provision and de-provision VMs to save costs depending upon the user demands or usage patterns. This automation can be based on a schedule to match common business hours or actual resource utilization.
Option D is incorrect. Identifying the common possible issues in the current configuration is not the primary use of automated scaling.
