Developing Solutions for Microsoft Azure (AZ-204) Practice Exam

Which statement correctly describes the concept of autoscaling?

1. Requires continuous monitoring by an administrator

2. Is a solution for scaling out or scaling in resources

3. Provides better availability than scaling up/down

4. Is only effective for static workloads

The correct answer is: Is a solution for scaling out or scaling in resources

The statement that accurately describes the concept of autoscaling is that it is a solution for scaling out or scaling in resources. Autoscaling is a feature typically utilized in cloud environments, including Microsoft Azure, to automatically adjust the number of active resources based on real-time demand. This capability enables applications to adapt to varying load conditions without the need for manual intervention, which optimizes resource allocation and can lead to cost savings. When demand increases, autoscaling can automatically provision additional resources (scaling out), and when demand decreases, it can release resources (scaling in). This flexibility is beneficial for applications that experience fluctuating workloads, ensuring performance and responsiveness. While continuous monitoring by an administrator is crucial for effective autoscaling strategies, it is not a defining characteristic of what autoscaling is. Similarly, autoscaling enhances availability, but that aspect alone doesn’t encompass its full definition. Lastly, autoscaling is not limited to static workloads; in fact, it is most beneficial for dynamic environments where workloads can change unpredictably.
