You plan to deploy multiple instances of an Azure web app across several Azure regions.
You need to design an access solution for the app. The solution must meet the following replication requirements:
Support rate limiting.
Balance requests between all instances.
Ensure that users can access the app in the event of a regional outage.
Solution: You use Azure Application Gateway to provide access to the app.
Does this meet the goal?

You plan to deploy an app that will use an Azure Storage account.
You need to deploy the storage account. The solution must meet the following requirements:
* Store the data of multiple users.
* Encrypt each user's data by using a separate key.
* Encrypt all the data in the storage account by using Microsoft keys or customer-managed keys.
What should you deploy?

Your company, named Contoso, Ltd, implements several Azure logic apps that have HTTP triggers: The logic apps provide access to an on-premises web service.
Contoso establishes a partnership with another company named Fabrikam, Inc.
Fabrikam does not have an existing Azure Active Directory (Azure AD) tenant and uses third-party OAuth 2.0 identity management to authenticate its users.
Developers at Fabrikam plan to use a subset of the logics apps to build applications that will integrate with the on-premises web service of Contoso.
You need to design a solution to provide the Fabrikam developers with access to the logic apps. The solution must meet the following requirements:
Requests to the logic apps from the developers must be limited to lower rates than the requests from the users at Contoso.
The developers must be able to rely on their existing OAuth 2.0 provider to gain access to the logic apps.
The solution must NOT require changes to the logic apps.
The solution must NOT use Azure AD guest accounts.
What should you include in the solution?

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?
