Exam AZ-900 topic 1 question 66 discussion

custom app in first-line tells that it can,t be SaaS. Multiple installations in last line of the question tells that its can't be PaaS. In pAAS , u dont install stuff, only application files and data are to be given in Paas. option left IaaS.

I believe it should be PaaS, Can someone please confirm. My exam is in 3 days.

it can both B and C. Azure VM (Iaas) or Azure Kubernetes (Paas) if your application is in a container. C is the common answer but both B and C are technically correct

To deploy this , you need to use VM which is IAAS

For deploying custom applications with several prerequisite applications and services in Azure, the recommended solution is Azure Virtual Machines (VMs) under an IaaS (Infrastructure as a Service) model. This provides the flexibility to configure the environment as needed.

I read 3 parts in this question that triggers me. custom application and installed. Saas is not suitable because you cannot install custom applications. PaaS is not suited because of CUSTOM applications. IaaS is the right anwser in this scenario because you can install custom application with specific requirements and dependencies.

For deploying several custom applications to Azure, especially when these applications have specific prerequisites and services, the best recommendation is Platform as a Service (PaaS) (Option B). PaaS provides a managed environment where you can build, deploy, and scale your applications without worrying about the underlying infrastructure. It offers several benefits: Managed Infrastructure: Azure handles the maintenance, patching, and updates of the infrastructure, allowing you to focus on your application development. Scalability: PaaS solutions can automatically scale to meet demand, ensuring your applications remain responsive. Integrated Services: PaaS often includes built-in services like databases, identity management, and monitoring, which can simplify the development and deployment process12. Using PaaS will minimize the administrative effort required to manage the applications and their dependencies, making it an ideal choice for your scenario.

Used Copilot and copy-pasted the question. The answer was PaaS.

Segun copilot... B. Plataforma como servicio (PaaS) Las soluciones PaaS proporcionan un entorno gestionado para desarrollar, ejecutar y gestionar aplicaciones sin preocuparse por la infraestructura subyacente. Esto incluye servicios como Azure App Service, Azure SQL Database, Azure Functions, entre otros, que permiten una implementación eficiente y escalable de tus aplicaciones.

PaaS provides a framework that developers can build upon to develop or customize cloud-based applications. https://azure.microsoft.com/en-us/resources/cloud-computing-dictionary/what-is-paas/

KEY WORD = CUSTOM, INSTALLATIONS

IaaS is the most suitable option for deploying several custom applications with specific prerequisite applications and services installed. It provides the flexibility to configure the underlying infrastructure (such as virtual machines, storage, and networking) according to the requirements of the applications. This level of control is necessary when you need to install and manage prerequisite applications and services.

The company wants to deploy "Custom" applications to Azure. These applications are like software tools they've created for specific purposes.

The applications will provide invoices to clients, this mean is managed by the user and not the cloud service provider. IaaS is the proper answer.

This sounds like a "best-case scenario" for Azure Container Instances (ACI), or even better, Azure Kubernetes Services (AKS). Both of those are typical examples of PaaS services.

From MS practice test hope this helps Question 12 of 50 Your organization is building a custom application. You need to focus on application development rather than configuration and management of servers. Which cloud service model should you use? Your Answer platform as a service (PaaS)

The keyword is prerequisites, so it’s IaaS.
