Microsoft Azure Architect Design (AZ-304) Practice Test

In the context of Azure, which technology allows for quick scaling and high-speed calculations across multiple nodes?

1. Azure Batch

2. Blob Storage

3. Azure API Management

4. Service Bus

The correct answer is: Azure Batch

Azure Batch is designed specifically for high-performance computing (HPC) applications and allows for the scaling of compute resources across multiple nodes rapidly. It manages the execution of large-scale parallel and batch computing workloads, enabling users to handle complex computations efficiently. With Azure Batch, you can easily configure pools of virtual machines to process tasks concurrently, which is particularly useful for scenarios like rendering images, processing large datasets, or performing simulations that require significant computing power. This technology is ideal for scenarios where workloads can be distributed and processed in parallel, optimizing resource utilization and reducing the time needed to complete large computation tasks. You can automatically scale compute resources up or down based on the workload, which enhances flexibility and cost-effectiveness. The other options do not provide the same capabilities for rapid scaling and high-speed distributed calculations. Blob Storage is primarily for storing unstructured data, Azure API Management is about managing APIs, and Service Bus facilitates messaging between applications, none of which focus on the specific needs of parallel processing or computational workloads.
