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?

You have 100 servers that run Windows Server 2012 R2 and host Microsoft SQL Server 2012 R2 instances.
The instances host databases that have the following characteristics:
* The largest database is currently 3 TB. None of the databases will ever exceed 4 TB.
* Stored procedures are implemented by using CLR.
You plan to move all the data from SQL Server to Azure.
You need to recommend an Azure service to host the databases. The solution must meet the following requirements:
* Whenever possible, minimize management overhead for the migrated databases.
* Minimize the number of database changes required to facilitate the migration.
* Ensure that users can authenticate by using their Active Directory credentials.

Explanation:
Box 1: Azure Application Gateway
Azure Application Gateway provides an application delivery controller (ADC) as a service. It offers various layer 7 load-balancing capabilities for your applications.
Box 2: Web Application Firwewall (WAF)
Application Gateway web application firewall (WAF) protects web applications from common vulnerabilities and exploits.
This is done through rules that are defined based on the OWASP core rule sets 3.0 or 2.2.9.
There are rules that detects SQL injection attacks.

Explanation:
An on-premises network gateway can exchange routes with an Azure virtual network gateway using the border gateway protocol (BGP). Using BGP with an Azure virtual network gateway is dependent on the type you selected when you created the gateway. If the type you selected were: ExpressRoute: You must use BGP to advertise on-premises routes to the Microsoft Edge router. You cannot create user-defined routes to force traffic to the ExpressRoute virtual network gateway if you deploy a virtual network gateway deployed as type:
ExpressRoute. You can use user-defined routes for forcing traffic from the Express Route to, for example, a Network Virtual Appliance.
