Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

Which of the following statements is true about Azure's scalability?

1. It requires manual intervention for scaling operations

2. It can automatically adjust resources based on demand

3. It is limited to virtual machines

4. It can only scale down resources

The correct answer is: It can automatically adjust resources based on demand

The statement that Azure can automatically adjust resources based on demand is correct. This feature of Azure is known as "auto-scaling," which allows Azure services to dynamically scale up or down based on the workload requirements. This capability is particularly beneficial in managing fluctuating workloads without requiring manual intervention, ensuring that applications remain efficient and cost-effective. Azure's scalability includes not just virtual machines, but encompasses a wide range of services like Azure App Service, Azure Kubernetes Service, and databases. This means that scaling can apply across various components and not just to a single type of resource. The ability to automatically manage resources helps businesses respond quickly to changing demands, enhancing performance while minimizing waste. This flexibility is a significant advantage of using cloud services like Azure.
