Please read the requirements: Many are not noting here the load balancing fact. The web apps will use custom domains. (Basic, Shared and standard Support custom domain) The web apps each require 10 GB of storage. (basic and standard support this) The web apps must each run in dedicated compute instances.(basic support 3 instance max where standard support 10max) Load balancing between instances must be included. (free, shared and basic dont support load balancing. standard and above tier only support load balancing/autosacling) Costs must be minimized. Standard is less costier than premimum and isolated. I hope this is clear to chose the correct answer as STANDARD. https://azure.microsoft.com/en-us/pricing/details/app-service/windows/

the Answer is Standard : Standard tier support Custom Domains, Disk Space of 50GB wich is more than enough for the requested plan, and as long as they want to run each web app in a dedicated instance, that means we need 10 dedicated instances for the 10 web apps with a load-balancing service between them, the basic plan only support up to 3 dedicated instances. Finally the Standard plan has the lowest cost compared to Premuim and Isolated pricing tiers.

As per explanation from BinuRaj

Basic meets all the requirements. Not sure why they would ask questions which can be googled. No point in memorizing data

This is not a part of AZ-900

Standard is then correct one

The Basic web tier in Azure App Service may not fully meet all the specified requirements. While it supports custom domains, it does not provide dedicated compute instances or load balancing between instances. The Basic tier shares resources among multiple applications and lacks features such as auto-scaling and deployment slots. For the given requirements, you might want to consider the Standard or Premium tier. Both the Standard and Premium tiers offer dedicated compute instances, load balancing, custom domains, and additional features. The choice between Standard and Premium would depend on specific features required and cost considerations. In summary, the Basic web tier might not suffice for the specified requirements, and you may need to explore the Standard or Premium web tier plans for a more comprehensive solution.

the answer is standard, the answer lies here. https://azure.microsoft.com/en-us/pricing/details/app-service/windows-previous/

Basic tier meets all the requirements. The 3 instances that others are talking about is for scaling out, i.e. you can increase the VMs to a maximum of 3 should each Web app demand that. Off course, there is also the scale up, which is increasing the CPU, memory on one VM. ✑ The web apps will use custom domains. - Basic supports this ✑ The web apps each require 10 GB of storage. - Basic supports 10Gb per instance ✑ The web apps must each run in dedicated compute instances. - Basic supports this ✑ Load balancing between instances must be included. - Basic supports integrated LB ✑ Costs must be minimized.

the Answer is Standard : The requirement for 10 web applications does not necessarily mean that a single Standard plan can accommodate all of them. Each web application is typically associated with an individual instance of an App Service Plan. In this scenario, if you have 10 web applications, you would generally need 10 separate Standard plans for web services. The "Maximum instances" in the Standard plan refers to the maximum number of instances that a single App Service Plan can scale out to, but it's not directly related to the total number of web applications you have. Each web application would be associated with its own plan, and the "Maximum instances" setting would apply to each plan individually. The crucial factor in determining the appropriate Azure web tier plan in this scenario is the requirement that "Load balancing between instances must be included." Only the "Standard" plan provides built-in load balancing functionality, making it the suitable choice to meet the specified requirement.

I´d suggest you pay one plan per app, so the 10GB for BASIC are sufficient

hello my fellow robots. Just finished my exam today with a 900 score. I just want to help you guys out and I made a list with all the common questions and answers you need to know. The following questions where often and will help you out in finishing your exam:28,44,46,55,72,80,91,94,95,97,100,107,111,128,134,138,149,151,159,227,258,269,277,278,296,307,331,337,330/350,353,354,394,398,401,405,407

while standard support Up to 10 instances therefore the correct answer is A (Standard)

Just follow the requirements, 10 GB of storage for EACH web app, so Basic wouldn't meet the requirements. So it is Standard plan.

Answer is standard

Due to the number of instances it appears to be Standard

Para atender aos requisitos mencionados, o plano de nível da web do Azure mais apropriado a ser usado é o "Padrão". Aqui está o raciocínio: A. Padrão: - Permite o uso de domínios personalizados. - Oferece 50 GB de armazenamento, que é mais do que suficiente para os 10 aplicativos web, cada um requerendo 10 GB. - Fornece instâncias de computação dedicadas. - Inclui balanceamento de carga entre instâncias, o que é importante para garantir a alta disponibilidade e escalabilidade dos aplicativos. - Embora possa ser um pouco mais caro do que o plano "Básico" ou "Grátis", atende a todos os requisitos e é a escolha mais apropriada para hospedar os aplicativos web com base nos requisitos fornecidos. Portanto, a resposta correta é a opção: A. Padrão
