Microsoft Azure Fundamentals AZ-900 Practice Question

Selecting the correct size for a virtual machine is critical as it defines the amount of computing resources such as CPU and memory the virtual machine will have. The size determines the performance characteristics of the VM and affects the cost. Specifying the region is also required for VM creation, but this choice primarily affects data sovereignty and latency, not the compute capacity itself. While resource groups and virtual networks are critical components for organizing and providing services to a VM, they do not define its compute power.
