A company has custom ASP.NET and Java applications that run old versions of Windows and Linux. The company plans to place applications in containers.
You need to design a solution that includes networking, service discovery, and load balancing for the applications. The solution must support storage orchestration.
Solution: Deploy a Kubernetes cluster that has the desired number of instances of the applications.

Show Suggested Answer

Suggested Answer: B 🗳️
Instead you should deploy each application to an Azure Container instance.
Note: Docker Containers are the global standard and are natively supported in Azure, offering enterprises an interesting and flexible way to migrate legacy apps for both future proofing and cost benefits.

I don't get why "No" is the correct answer here? Azure Container Instances is a great solution for any scenario that can operate in isolated containers, including simple applications, task automation, and build jobs. For scenarios where you need full container orchestration, including service discovery across multiple containers, automatic scaling, and coordinated application upgrades, we recommend Azure Kubernetes Service (AKS). https://docs.microsoft.com/en-us/azure/container-instances/container-instances-overview

The answer will be B(No). The reason being, AKS does not support older windows server versions. It supports Windows 2019 only. Refer below link from Microsoft docs: https://docs.microsoft.com/en-us/azure/aks/faq#can-i-run-windows-server-containers-on-aks

It has to be AKS as Azure Load Balancer - Placing an Azure Load Balancer in front of container instances in a networked container group is not supported https://docs.microsoft.com/en-us/azure/container-instances/container-instances-vnet

No, as per https://docs.microsoft.com/en-us/azure/aks/windows-faq "AKS uses Windows Server 2019 as the host OS version and only supports process isolation. Container images built using other Windows Server versions are not supported."

I think AKS need win 2019 to run, but the question indicates the ASP.NET runs on older version of Windows ( Not AKS). So your reference is talking about different thing. AKS is the correct answer, among other things, as far as I know, Container Instance doesn't support Storage Orchestration by itself.

I think the answer is correct. AKS has limited support for Windows and it's in preview feature. In such case we should use Container Services. check this article. https://docs.microsoft.com/en-us/dotnet/architecture/modernize-with-azure-containers/modernize-existing-apps-to-cloud-optimized/when-to-deploy-windows-containers-to-azure-container-service-kubernetes

I would choose also no, because Container Service is what they expect. Kubernetes is oversized in my opinion. See also next Question here in examtopics. There they will ask if Container Instance would be the right choice.

Hello, in this question there is no mention about Azure, only about 2 apps Java and .Net to be placed in containers. A Kubernete Cluster installed onprem would fulfill this request: https://kubernetes.io/docs/setup/production-environment/windows/intro-windows-in-kubernetes/ I think that this question is not correct and something is missing in the text. From tech perspective the answer is ok if you ignore Azure. If we refere to Azure then the answer is No. We have to use AKS.

I don't think kubernetes would work very well, specially with the requirement that "applications that run old versions of Windows and Linux"

Guys, the questions doesn't mention Azure Kubernet Services - AKS, only kubernetes cluster, which is different. But also, Kubernetes is nothing more than an orchestration tool to work with containers, so, but it doesn't offer service discovery...

My mistake here. K8s DOES Service discovery. So, I'd click yes too. https://platform9.com/blog/kubernetes-service-discovery-principles-in-practice/

I think at the time the exam was written, AKS did not support Windows. Have to remember, the questions on the exam, will be based on what was available at the time the exam was written. So in that thinking, NO is the correct answer.
