Question#113

HOTSPOT -
You have an Azure Active Directory (Azure AD) tenant.
You want to implement multi-factor authentication by making use of a conditional access policy. The conditional access policy must be applied to all users when they access the Azure portal.

Answer:
Box 1:
The conditional access policy must be applied or assigned to Users and Groups.
Box 2:
The conditional access policy must be applied when users access the Azure portal, which is a cloud app. That is: Microsoft Azure Management
Box 3:
Access control must require multi-factor authentication when granting access.

Question#114

You manage an Azure SQL database that allows for Azure AD authentication.
You need to make sure that database developers can connect to the SQL database via Microsoft SQL Server Management Studio (SSMS). You also need to make sure the developers use their on-premises Active Directory account for authentication. Your strategy should allow for authentication prompts to be kept to a minimum.
Which of the following should you implement?

  • A. Azure AD token.
  • B. Azure Multi-Factor authentication.
  • C. Active Directory integrated authentication.
  • D. OATH software tokens.
Discover Answer Hide Answer

Answer: C
Azure AD can be the initial Azure AD managed domain. Azure AD can also be an on-premises Active Directory Domain Services that is federated with the Azure
AD.
Using an Azure AD identity to connect using SSMS or SSDT
The following procedures show you how to connect to a SQL database with an Azure AD identity using SQL Server Management Studio or SQL Server Database
Tools.
Active Directory integrated authentication
Use this method if you are logged in to Windows using your Azure Active Directory credentials from a federated domain.
1. Start Management Studio or Data Tools and in the Connect to Server (or Connect to Database Engine) dialog box, in the Authentication box, select Active
Directory - Integrated. No password is needed or can be entered because your existing credentials will be presented for the connection.

2. Select the Options button, and on the Connection Properties page, in the Connect to database box, type the name of the user database you want to connect to.
(The AD domain name or tenant IDג€ option is only supported for Universal with MFA connection options, otherwise it is greyed out.)

Question#115

You are developing an application to transfer data between on-premises file servers and Azure Blob storage. The application stores keys, secrets, and certificates in Azure Key Vault and makes use of the Azure Key Vault APIs.
You want to configure the application to allow recovery of an accidental deletion of the key vault or key vault objects for 90 days after deletion.
What should you do?

  • A. Run the Add-AzKeyVaultKey cmdlet.
  • B. Run the az keyvault update --enable-soft-delete true --enable-purge-protection true CLI.
  • C. Implement virtual network service endpoints for Azure Key Vault.
  • D. Run the az keyvault update --enable-soft-delete false CLI.
Discover Answer Hide Answer

Answer: B
When soft-delete is enabled, resources marked as deleted resources are retained for a specified period (90 days by default). The service further provides a mechanism for recovering the deleted object, essentially undoing the deletion.
Purge protection is an optional Key Vault behavior and is not enabled by default. Purge protection can only be enabled once soft-delete is enabled.
When purge protection is on, a vault or an object in the deleted state cannot be purged until the retention period has passed. Soft-deleted vaults and objects can still be recovered, ensuring that the retention policy will be followed.
The default retention period is 90 days, but it is possible to set the retention policy interval to a value from 7 to 90 days through the Azure portal. Once the retention policy interval is set and saved it cannot be changed for that vault.

Question#120

You develop a Web App on a tier D1 app service plan.
You notice that page load times increase during periods of peak traffic.
You want to implement automatic scaling when CPU load is above 80 percent. Your solution must minimize costs.
What should you do first?

  • A. Enable autoscaling on the Web App.
  • B. Switch to the Premium App Service tier plan.
  • C. Switch to the Standard App Service tier plan.
  • D. Switch to the Azure App Services consumption plan.
Discover Answer Hide Answer

Answer: C
Configure the web app to the Standard App Service Tier. The Standard tier supports auto-scaling, and we should minimize the cost. We can then enable autoscaling on the web app, add a scale rule and add a Scale condition.
