Exam AZ-900 topic 1 question 7 discussion

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.

O padrao sempre é o mais barato, e tem o balanceamento de cargas

Standard is mandatory because of the load balancing requirement Basic would work if not for load balancing (saves ~50% cost) Shared exists but is useless for your scenario (it's essentially "Free+")

A. Standard Explanation: Let's analyze the requirements against each plan: Requirement Free Shared Basic Standard Custom Domains ❌ No ✅ Yes ✅ Yes ✅ Yes 10 GB Storage per App ❌ No ❌ No ✅ Yes ✅ Yes Dedicated Compute Instances ❌ No ❌ No ✅ Yes ✅ Yes Load Balancing Included ❌ No ❌ No ❌ No ✅ Yes Minimized Costs ✅ Free ✅ Low ✅ Moderate ❌ Higher (but required for features) Reasoning: Free and Shared Plans do not support dedicated compute instances. Basic Plan supports dedicated compute instances and custom domains but does not include load balancing. Standard Plan supports all the required features, including load balancing, making it the best choice.

Correct answer should be A. Standard. The reason seems to be explicit here https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/azure-subscription-service-limits#azure-app-service-limits. Analyzing the request: - web apps will use custom domain (Standard ✅, Basic ✅, Free ❌, Shared ✅) so we exclude already 'Free' - web apps each require 10 GB of storage (Standard ->50 GB ✅, Basic -> 10 GB ✅, Shared -> 1GB ❌) - Each must run in dedicated compute instances (ONLY Standard supports 10 dedicated instances) so STANDARD is the response.

The Standard service plan is designed for running production workloads. Pricing is based on the size and number of instances you run. Built-in network load balancing support automatically distributes traffic across instances. The Basic service plan is designed for apps that have lower traffic requirements, and don't need advanced auto scale and traffic management features. Pricing is based on the size and number of instances you run. Built-in network load balancing support automatically distributes traffic across instances.

basic plan doesnt support load balancing

Explanation: Custom Domains: Both the Basic and Standard tiers support custom domains, a requirement for web apps. Storage Requirements: Each web app requires 10 GB of storage. The Standard tier provides up to 50 GB of storage, accommodating all 10 apps (10 GB × 10 = 100 GB total requirement). The Basic tier also offers 10 GB per instance, but it has limitations on scaling and instances. Dedicated Compute Instances: Both Basic and Standard tiers provide dedicated compute instances, ensuring that the web apps are not running on shared resources. Load Balancing: Load balancing between instances is included in the Standard tier but not in the Basic tier. This makes the Standard tier more suitable for production workloads requiring such features. Cost Minimization: While the Basic tier is cheaper than the Standard tier, it does not meet all the requirements (e.g., load balancing). The Standard tier provides a balance between cost and features necessary for production-grade hosting

The correct answer is: A. Standard the Standard plan best meets all requirements while balancing features and cost considerations.

B. Basic The Basic plan is more cost-effective and suitable for non-production environments, while the Standard plan provides additional features and support for production environments at a higher cost.

Yeah, you need standard.

Standard plan we must need and it is also cost effective than other plans

A. Standard Here's why: Custom Domains: The Standard plan supports custom domains. Storage: The Standard plan offers 50 GB of storage, which can accommodate 10 GB per web app. Dedicated Compute Instances: The Standard plan provides dedicated compute instances for each web app, unlike the Free or Shared tiers that share resources. Load Balancing: The Standard plan includes built-in load balancing across instances. Cost Minimization: The Standard plan is more cost-effective than the Premium plan, while still meeting all the necessary requirements.

Basic supports: Can host unlimited Web, mobile, or API apps - so this covers "Your developers have created 10 web applications that must be host on Azure" Basic supports custom domains which Web Apps require Basic also supports dedicated compute instances that web apps must each run on. Basic also supports Load balancing between instances (Built-in network load balancing support automatically distributes traffic across instances) What I don't understand is 10 GB per instance (3 for Basic) will be sufficient for 10 web apps that each require 10 GB of storage in Basic tier. Will that be 100GB of requirement in total and therefore you need to use Standard Plan (let's say one instance for each web app i.e. 10 instances which standard supports and 50 GB for each instance which is more than what's required).

FINALY AN END TO ALL THE ARGUMENTS !!!!!!!!!!!!!!!!!!!! YOU GUYS HAVE STRUGGLED A LOT FOR THE ANSWER . FINALLY YOU GET IT HERE :) Answer is B : BASIC Unlimited WebApps can be created per Azure App service Plan Custom Domain is supported in Basic Plan ..that too unlimited Compute instance type for each webApp is Dedicated with 10gb Storage..its not shared compute instance.That means 10 web app will have 10 dedicated compute instance of 10Gb each . Maximum instance that can be scaled out is 3 ....forget this point..not required in this question integrated load balancing is supported in basic Anybody who feels i am bluffing please go through this link.you will have to scroll down a bit to come to App service limits... ENJOY !! https://docs.microsoft.com/en-us/azure/azure-resource-manager/management/azure-subscription-service-limits#app-service-limits

Hi, Answer is unfortunately B. The wording of the question is bad though. Explanation : https://azure.microsoft.com/en-us/pricing/details/app-service/windows/#overview Customs domains : All but free 10G storage : Here is the confusion EACH web app requires 10GB does not mean 10 instances of ONE web app requires 10x10G = 100G or whatever. Its 10 DIFFERENT web apps. So BASIC is enough. Dedicated Compute Instances : Basic is enough. Load-balancing : Basic is enough. Don't mislead the scalability number. It works only if ONE specific web app is very consuming or you need high availability. Costs minimized : Here is the confusion. Nowhere it's written that all 10 web app must be in the same app service plan. You can have 10 app services for 10 web apps, or 2 app services fo 5 web apps each (standard). However I belive the question assumes 1 app service plan per web app, which one to choose ? This is why basic is preferred.
