You need to design a highly available Azure SQL database that meets the following requirements:
✑ Failover between replicas of the database must occur without any data loss.
✑ The database must remain available in the event of a zone outage.
✑ Costs must be minimized.
Which deployment option should you use?

You have an on-premises Hyper-V cluster that hosts 20 virtual machines. Some virtual machines run Windows Server 2016 and some run Linux.
You plan to migrate the virtual machines to an Azure subscription.
You need to recommend a solution to replicate the disks of the virtual machines to Azure. The solution must ensure that the virtual machines remain available during the migration of the disks.
Solution: You recommend implementing an Azure Storage account, and then using Azure Migrate.
Does this meet the goal?
Correct Answer:
B
To ensure that the virtual machines remain available during the migration, use Azure Site Recovery.

A
Azure Front Door enables you to define, manage, and monitor the global routing for your web traffic by optimizing for best performance and instant global failover for high availability. With Front Door, you can transform your global (multi-region) consumer and enterprise applications into robust, high-performance personalized modern applications, APIs, and content that reaches a global audience with Azure.
Front Door works at Layer 7 or HTTP/HTTPS layer and uses anycast protocol with split TCP and Microsoft's global network for improving global connectivity.
Incorrect Answers:
B: Azure Traffic Manager uses DNS (layer 3) to shape traffic. SSL works at Layer 6.
Azure Traffic Manager can direct customers to their closest AKS cluster and application instance. For the best performance and redundancy, direct all application traffic through Traffic Manager before it goes to your AKS cluster.

You need to design a solution that will execute custom C# code in response to an event routed to Azure Event Grid. The solution must meet the following requirements:
✑ The executed code must be able to access the private IP address of a Microsoft SQL Server instance that runs on an Azure virtual machine.
✑ Costs must be minimized.
What should you include in the solution?
Correct Answer:
D
When you create a function app in Azure, you must choose a hosting plan for your app. There are three basic hosting plans available for Azure Functions:
Consumption plan, Premium plan, and Dedicated (App Service) plan.
For the Consumption plan, you don't have to pay for idle VMs or reserve capacity in advance.
Connect to private endpoints with Azure Functions
As enterprises continue to adopt serverless (and Platform-as-a-Service, or PaaS) solutions, they often need a way to integrate with existing resources on a virtual network. These existing resources could be databases, file storage, message queues or event streams, or REST APIs.
