Your company purchases an app named App1.
You plan to run App1 on seven Azure virtual machines in an Availability Set. The number of fault domains is set to 3. The number of update domains is set to 20.
You need to identify how many App1 instances will remain available during a period of planned maintenance.
How many App1 instances should you identify?
Correct Answer:
C
Only one update domain is rebooted at a time. Here there are 7 update domain with one VM each (and 13 update domain with no VM).

You plan to deploy 10 applications to Azure. The applications will be deployed to two Azure Kubernetes Service (AKS) clusters. Each cluster will be deployed to a separate Azure region.
The application deployment must meet the following requirements:
✑ Ensure that the applications remain available if a single AKS cluster fails.
✑ Ensure that the connection traffic over the internet is encrypted by using SSL without having to configure SSL on each container instance.
Which Azure service should you include in the recommendation?
Correct Answer:
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.

Azure Automation now supports update management, inventory, and change tracking.
Update management delivers visibility of update compliance across Azure, on-premises, and other clouds for both Windows and Linux. Create scheduled deployments to orchestrate the installation of updates within a defined maintenance window. Exclude specific updates and get detailed troubleshooting logs to identify any issues during the deployment.
Incorrect Answers:
D: Azure Monitor metrics include:
✑ Model Deploy Started: Number of model deployments started in this workspace
✑ Model Deploy Succeeded: Number of model deployments that succeeded in this workspace
✑ Model Deploy Failed: Number of model deployments that failed in this workspace

You deploy Azure App Service Web Apps that connect to on-premises Microsoft SQL Server instances by using Azure ExpressRoute. You plan to migrate the
SQL Server instances to Azure.
Migration of the SQL Server instances to Azure must:
✑ Support automatic patching and version updates to SQL Server.
✑ Provide automatic backup services.
✑ Allow for high-availability of the instances.
✑ Provide a native VNET with private IP addressing.
✑ Encrypt all data in transit.
✑ Be in a single-tenant environment with dedicated underlying infrastructure (compute, storage)
You need to migrate the SQL Server instances to Azure.
Which Azure service should you use?
Correct Answer:
E
Azure SQL Database Managed Instance configured for Hybrid workloads. Use this topology if your Azure SQL Database Managed Instance is connected to your on-premises network. This approach provides the most simplified network routing and yields maximum data throughput during the migration.
