Answer: Create a virtual machine scale set with 10 VM instances
The correct answer is A: Create a virtual machine scale set with 10 VM instances. This is because a Virtual Machine Scale Set ensures that no more than 20% of the instances are undergoing maintenance at any time, meaning with 10 instances, at least 8 will always be running during planned maintenance. Availability Sets, on the other hand, distribute VMs across update and fault domains to manage maintenance but do not directly control the number of VMs running during maintenance as effectively as VM scale sets.
