Hotspot Question
You are designing an Azure we app. You plan to deploy the web app to the Europe Azure region and the West Europe region.
You need to recommend a solution for the web app. The solution must the following requirements:
- Users must always access the web app form the North region, unless
the region fails.
- The web app must be available to users if an Azure region is
unavailable.
- Deployment costs must be minimized.
What should you include in the recommendation? To answer, select the appropriate options in the area.
NOTE: Each correct selection is worth one point.

You have to deploy an Azure SQL database named db1 for your company. The databases must meet the following security requirements:
- When IT help desk supervisors query a database table named customers, they must be able to see the full number of each credit card
- When IT help desk operators query a database table named customers,
they must only see the last four digits of each credit card number
- A column named Credit Card rating in the customers table must never
appear in plain text in the database system.
- Only client applications must be able to decrypt the information that is stored in this column Which of the following can be implemented for the Credit Card rating column security requirement?

Case Study 3 - Contoso
Existing Environment: Technical Environment
The on-premises network contains a single Active Directory domain named contoso.com.
Contoso has a single Azure subscription.
Existing Environment: Business Partnerships
Contoso has a business partnership with Fabrikam, Inc. Fabrikam users access some Contoso applications over the internet by using Azure Active Directory (Azure AD) guest accounts.
Requirements: Planned Changes
Contoso plans to deploy two applications named App1 and App2 to Azure.
Requirements: App1
App1 will be a Python web app hosted in Azure App Service that requires a Linux runtime. Users from Contoso and Fabrikam will access App1.
App1 will access several services that require third-party credentials and access strings. The credentials and access strings are stored in Azure Key Vault.
App1 will have six instances: three in the East US Azure region and three in the West Europe Azure region.
App1 has the following data requirements:
* Each instance will write data to a data store in the same availability zone as the instance.
* Data written by any App1 instance must be visible to all App1 instances.
App1 will only be accessible from the internet. App1 has the following connection requirements:
* Connections to App1 must pass through a web application firewall (WAF).
* Connections to App1 must be active-active load balanced between instances.
* All connections to App1 from North America must be directed to the East US region. All other connections must be directed to the West Europe region.
Every hour, you will run a maintenance task by invoking a PowerShell script that copies files from all the App1 instances. The PowerShell script will run from a central location.
Requirements: App2
App2 will be a NET app hosted in App Service that requires a Windows runtime. App2 has the following file storage requirements:
* Save files to an Azure Storage account.
* Replicate files to an on-premises location.
* Ensure that on-premises clients can read the files over the LAN by using the SMB protocol.
You need to monitor App2 to analyze how long it takes to perform different transactions within the application. The solution must not require changes to the application code.
Application Development Requirements
Application developers will constantly develop new versions of App1 and App2. The development process must meet the following requirements:
* A staging instance of a new application version must be deployed to the application host before the new version is used in production.
* After testing the new version, the staging version of the application will replace the production version.
* The switch to the new application version from staging to production must occur without any downtime of the application.
Identity Requirements
Contoso identifies the following requirements for managing Fabrikam access to resources:
* Every month, an account manager at Fabrikam must review which Fabrikam users have access permissions to App1. Accounts that no longer need permissions must be removed as guests.
* The solution must minimize development effort.
Security Requirement
All secrets used by Azure services must be stored in Azure Key Vault.
Services that require credentials must have the credentials tied to the service instance. The credentials must NOT be shared between services.
What should you recommend to meet the monitoring requirements for App2?

You have an on-premises datacenter that contains 100 network shares. Each share contains more than 20 TB of data.
You have an Azure subscription.
You need to recommend a solution to migrate the network shares to Azure. The solution must provide bandwidth management for repeated transfers after the initial sync.
Which two services should you include in the recommendation? Each correct answer presents part of the solution.
NOTE: Each correct answer is worth one point.

You have an Azure subscription.
You need to recommend a solution to provide developers with the ability to provision Azure virtual machines. The solution must meet the following requirements:
- Only allow the creation of the virtual machines in specific regions.
- Only allow the creation of specific sizes of virtual machines.
What should you include in the recommendation?
