You need to deploy resources to host a stateless web app in an Azure subscription. The solution must meet the following requirements:

✑ Provide access to the full .NET framework.

✑ Provide redundancy if an Azure region fails.

✑ Grant administrators access to the operating system to install custom application dependencies.

Solution: You deploy two Azure virtual machines to two Azure regions, and you deploy an Azure Application Gateway.

Does this meet the goal?

Show Answer
Correct Answer: B

The requirements specify providing access to the full .NET framework, redundancy if an Azure region fails, and granting administrators access to the operating system to install custom application dependencies. Deploying two Azure virtual machines to two Azure regions meets the redundancy and operating system access requirements. However, using an Azure Application Gateway does not fulfill the requirement for redundancy across regions, as it is designed for regional load balancing. To achieve geo-redundancy, Azure Traffic Manager, which provides DNS-based traffic load balancing across global regions, should be used instead. Therefore, the solution does not fully meet the goal.

No is the right answer, App Gateway will balance the traffic between VMs deployed in the same region.

Azure Traffic Manager is a DNS-based traffic load balancer that enables you to distribute traffic optimally to services across global Azure regions, while providing high availability and responsiveness.

Application Gateway is Regional load-balancing service https://docs.microsoft.com/en-us/azure/architecture/guide/technology-choices/load-balancing-overview
