Which two actions should you perform?

You administer an Azure Active Directory (Azure AD) tenant that has a SharePoint web application named
TeamSite1. TeamSite1 accesses your Azure AD tenant for user information.The application access key for TeamSite1 has been compromised.
You need to ensure that users can continue to use TeamSite1 and that the compromised key does not allow
access to the data in your Azure AD tenant.
Which two actions should you perform? Each correct answer presents part of the solution.

A.
Remove the compromised key from the application definition for TeamSite1.

B.
Delete the application definition for TeamSite1.

C.
Generate a new application key for TeamSite1.

D.
Generate a new application definition for TeamSite1.

E.
Update the existing application key.

Explanation:
One of the security aspects of Windows Azure storage is that all access is protected by access keys.
It is possible to change the access keys (e.g. if the keys become compromised), and if changed, we’d need to
update the application to have the new key.
