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. Which service should you include in the recommendation?

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 plan to deploy an Azure Database for MySQL flexible server named Server1 to the East US Azure region. You need to implement a business continuity solution for Server1. The solution must minimize downtime in the event of a failover to a paired region. What should you do?

You have an Azure subscription that contains the resources shown in the following table. You need to recommend a load balancing solution that will distribute incoming traffic for VMSS1 across NVA1 and NVA2. The solution must minimize administrative effort. What should you include in the recommendation?

You have an Azure subscription that contains a Basic Azure virtual WAN named VirtualWAN1 and the virtual hubs shown in the following table. You have an ExpressRoute circuit in the US East Azure region. You need to create an ExpressRoute association to VirtualWAN1. What should you do first?

You have an Azure subscription that contains a storage account. An application sometimes writes duplicate files to the storage account. You have a PowerShell script that identifies and deletes duplicate files in the storage account. Currently, the script is run manually after approval from the operations manager. You need to recommend a serverless solution that performs the following actions: • Runs the script once an hour to identify whether duplicate files exist • Sends an email notification to the operations manager requesting approval to delete the duplicate files • Processes an email response from the operations manager specifying whether the deletion was approved • Runs the script if the deletion was approved What should you include in the recommendation?

Your company has the infrastructure shown in the following table. The on-premises Active Directory domain syncs with Azure Active Directory (Azure AD). Server1 runs an application named App1 that uses LDAP queries to verify user identities in the on-premises Active Directory domain. You plan to migrate Server1 to a virtual machine in Subscription1. A company security policy states that the virtual machines and services deployed to Subscription1 must be prevented from accessing the on-premises network. You need to recommend a solution to ensure that App1 continues to function after the migration. The solution must meet the security policy. What should you include in the recommendation?
