Azure App Service Tier Selection for Custom Domain and Storage

AZ-900 By islever Editorial Last updated

Describe the core architectural components of Azure

Short answer

A Use the Standard web tier plan to support the custom domain, SSL, multi-instance deployment, and the required 12 GB of storage exceeding the Basic tier's 10 GB limit.

Question

Your developers have created a portal web app for users in the Miami branch office. The web app will be publicly accessible and used by the Miami users to
retrieve customer and product information. The web app is currently running in an on-premises test environment.
You plan to host the web app on Azure.
You need to determine which Azure web tier plan to host the web app. The web tier plan must meet the following requirements:
✑ The website will use the miami.weyland.com URL.
✑ The website will be deployed to two instances.
✑ SSL support must be included.
✑ The website requires 12 GB of storage.
✑ Costs must be minimized.
Which web tier plan should you use?
  1. Standard Correct Answer
  2. Basic
  3. Free
  4. Shared

Key Takeaways

The trap is assuming Basic is cheaper; however, its 10 GB disk limit fails the 12 GB requirement, making Standard the minimum viable option.

This question tests the selection of an Azure App Service plan that supports custom domains, SSL, and at least 12 GB of storage. The Standard tier is required because the Basic tier's 10 GB limit is insufficient.

Common mistake: Learners often choose Basic (B) because it is cheaper than Standard and meets most requirements, but they overlook the specific 12 GB storage constraint which exceeds Basic's 10 GB limit.

Expert Analysis

Why the Answer Is Correct

The Standard tier (A) is the correct choice because it provides dedicated compute instances, supports custom domains (miami.weyland.com), includes SSL support, allows scaling to multiple instances, and offers 50 GB of local storage. This meets all constraints while minimizing cost compared to higher tiers like Premium.

Why the Other Options Are Wrong

Basic (B) is incorrect because it only provides 10 GB of local storage, failing the 12 GB requirement. Free (C) and Shared (D) tiers do not support custom domains or dedicated instances and have very limited storage (1 GB).

Community Comment Notes

Community consensus strongly favors Standard due to the storage limit. As AntonioTech noted, "Standard... allows you to use custom domains... scale out to multiple instances." Omsdigital confirmed, "basic checks all except STORAGE... Basic ends with 10GB," highlighting that Basic cannot meet the 12 GB requirement.

Exam Strategy

Always check the storage limits of App Service tiers when a specific GB amount is mentioned in the requirements. Remember that Basic has a 10 GB limit, so any requirement above that forces you to Standard.

Frequently Asked Questions

Why can't I use the Basic tier if it's cheaper?

Basic tier only provides 10 GB of local storage. Since the requirement is 12 GB, Basic is insufficient regardless of cost savings.

Does Standard tier include free SSL certificates?

Standard tier supports custom SSL certificates and TLS/SSL termination, but you must provide your own certificate unless using Azure Managed Certificates.

    The answer is A. Standard The Standard web tier plan in Azure App Service meets the specified requirements: Custom Domain (miami.weyland.com): The Standard plan allows you to use custom domains, so you can set up the miami.weyland.com URL for the website. Two Instances: The Standard plan provides the ability to scale out to multiple instances, which fulfills the requirement to deploy the website to two instances. SSL Support: The Standard plan includes SSL support, which is necessary for secure communication over HTTPS. Storage (12 GB): The Standard plan includes sufficient storage for the 12 GB requirement. Costs Minimization: While the Standard plan might not be the lowest-cost option compared to Free, Basic, or Shared plans, it provides the necessary features and capacity for the given requirements. Given that the website will be publicly accessible, require SSL, need multiple instances, and have a custom domain, the Standard plan is the most appropriate choice that meets all the criteria.

    The answer is A. Here is some difference between Basic and Standard 1. Basic Tier: The Basic tier provides a cost-effective option for hosting small-scale web applications with fewer advanced features. It offers features such as manual scaling, limited auto-scaling, deployment slots, and basic monitoring. It is suitable for simple web apps with low traffic or development/testing environments. 2. Standard Tier: The Standard tier provides additional features and capabilities compared to the Basic tier. It includes features like advanced auto-scaling, traffic routing, deployment slots with testing in production, integration with Azure Application Insights for detailed monitoring, and support for custom domain SSL certificates. It is suitable for production-grade web applications with moderate to high traffic or those requiring more advanced functionality.

    Yep correct - dont get me wrong basic checks all except STORAGE. The question is asking for 12 storage and basic ends with 10GB. Other than that basic does the other requirement - yes to ssl - Yes to custom domain and 3 instance. go and google summary of key features across tiers.
  4. raviTy 👍 4
    Answer is correct as 12GB is required, Standard has 50GB of limit. Basic only has 10 GB

    A. Standard The Standard web tier plan is the most appropriate option for hosting the web app that meets the given requirements. The Standard tier plan provides dedicated compute instances for the web app, which can be scaled independently. It also provides load balancing between instances to ensure high availability and scalability.

    B. Basic Explanation: The Basic tier includes support for Unlimited SNI SSL connections, which fulfills the SSL support requirement for the web app. The Basic tier also supports scaling to multiple instances, allowing you to deploy the web app to two nodes for increased availability and performance. The Basic tier provides load balancer support, which can distribute incoming traffic across the instances for improved performance and reliability. Each instance in the Basic tier can have up to 10 GB of storage, and since you require a total of 12 GB of storage, you can allocate 10 GB of storage to each of the two instances. The Basic tier is cost-effective and suitable for small to medium-scale applications, helping to minimize costs while meeting the specified requirements. Option A, Standard, is also a valid choice, but considering the cost optimization requirement, the Basic tier would be a more cost-effective solution while still meeting the necessary requirements for the web app.

    it's a because the other ar lower than they give and the only one is standaard and that has a storage of 50GB and the other are lower than 10 GB and the requirments are 12 GB
  15. TT39 👍 1 Answered A
    ✔ SSL support ✔ Supports multiple instances (scaling) ✔ 50 GB storage (exceeds 12 GB requirement) ✔ Built-in load balancing ✔ Lowest tier that fully meets all requirements

    15GB of storage is required and we have to reduce cost So the most suitable is A. Stantard https://azure.microsoft.com/en-us/pricing/details/app-service/windows/
  17. NOTEBOOK_789 👍 1
    For this line- The website requires 12 GB of storage.- It should be standard, because Basic provides upto 10gb of storage and all other options will be costly
  18. Bozho 👍 1
    10 0.075 > 2 0.10, so 2 Standard plans are cheaper than 10 Basic ones and have the 100 GB of needed total storage. They will host 5 apps each.
