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

The primary benefit of using Azure's serverless architecture is that it eliminates the need for management. This model allows developers to focus on building applications and writing code without worrying about the underlying infrastructure, server provisioning, or maintenance. In a serverless environment, resources are automatically managed by Azure, scaling up or down according to demand, which leads to efficient resource use and reduced operational overhead. This allows for faster development cycles and enables teams to concentrate on delivering value through their applications rather than managing servers.

The other options provided, while they may have benefits in different contexts, do not capture the primary advantage of serverless architecture as effectively. Always-on services imply a constant availability that may not align with the pay-as-you-go model of serverless computing. Enhanced security is indeed a consideration with any cloud service, but it is not a unique feature of serverless architecture. Structured data storage relates more to database services that Azure provides, which doesn't directly pertain to the serverless concept.
