Microsoft Azure Architect Design (AZ-304) Practice Test

For applications that run on old versions of Windows and Linux, what is a proposed method for transitioning to containers?

1. Deploy Azure Functions

2. Create virtual machines

3. Use Azure Container Registry

4. Utilize a Kubernetes cluster

The correct answer is: Utilize a Kubernetes cluster

Utilizing a Kubernetes cluster is a highly effective method for transitioning applications that run on older versions of Windows and Linux into a containerized environment. Kubernetes provides an orchestration platform that not only helps manage current containerized applications but also allows for scaling and automating deployment processes. For legacy applications, the transition to containers might involve re-packaging and potentially modifying the applications to function effectively within a containerized system. Kubernetes offers multiple advantages in this context: it supports running both Windows and Linux containers, thus providing flexibility for applications that may not have straightforward transitions. The ability of Kubernetes to manage pod deployments, handle service discovery, and maintain desired state configurations makes it ideal for managing the complexities introduced when transitioning from traditional environments to modern, container-based architectures. Moreover, Kubernetes provides resilience and resource management features that allow for better optimization and performance monitoring of the transitioned applications. These capabilities are essential when dealing with the intricacies of older applications that might require specific configurations to run smoothly in containers. In contrast, options like deploying Azure Functions or using Azure Container Registry might not adequately address the full lifecycle management and orchestration needs of transitioning existing applications. Creating virtual machines could offer a temporary solution but does not align with the goal of modernizing applications towards a containerized architecture,
