NEW QUESTION 2

You are developing an Azure web application to store and archive patient medical records in Azure. You need to configure data storage to meet the following policies:
• Ensure that you can configure a retention period for patient records.
• Archived data must be readable.
• Archived data must not be modified or deleted. Which Azure storage service should you use?

• A. Azure files

Answer: C

NEW QUESTION 3

You need to resolve a notification latency issue.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point

• A. Ensure that the Azure Function is using an App Service plan.
• B. Set Always On to false
• C. Ensure that the Azure Function is set to use a consumption plan.
• D. Set Always On to true.

Answer: AD

Explanation:
Azure Functions can run on either a Consumption Plan or a dedicated App Service Plan. If you run in a dedicated mode, you need to turn on the Always On setting for your Function App to run properly. The Function runtime will go idle after a few minutes of inactivity, so only HTTP triggers will actually "wake up" your functions. This is similar to how WebJobs must have Always On enabled.
Scenario: Notification latency: Users report that anomaly detection emails can sometimes arrive several minutes after an anomaly is detected.
Anomaly detection service: You have an anomaly detection service that analyzes log information for anomalies. It is implemented as an Azure Machine Learning model. The model is deployed as a web service.
If an anomaly is detected, an Azure Function that emails administrators is called by using an HTTP WebHook. References:

NEW QUESTION 9

A company is developing a software as a service (SaaS) solution in Azure for other business to manage customers. The solution includes the following Azure SQL Database instances. Customer data exists in all databases.

Customers may request that the company remove data that relates to the customer. If a customer makes a deletion request, all details from the customer must be removed from the solution. All deletions for a customer must occur in one distributed transaction that includes the CRM, ERP, and Marketing databases.
You need to activate support for transactions over multiple databases on the same logical server and activate support for transactions over multiple servers.
Which actions and Azure PowerShell command should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

• A. Mastered
• B. Not Mastered

Answer: A

Explanation:
Box 1: Use a transaction scope
The TransactionScope class establishes an ambient transaction in .NET. (An “ambient transaction” is one that lives in the current thread.) All connections opened within the TransactionScope participate in the transaction. If different databases participate, the transaction is automatically elevated to a distributed transaction.
Box 2: New-AzureRmSqlServerCommunicationLink
New-AzureRmSqlServerCommunicationLink: Use this cmdlet to create a new communication relationship between two logical servers in Azure SQL DB. The relationship is symmetric which means both servers can initiate transactions with the other server.

NEW QUESTION 13

You are creating a collaborative image hosting platform as an ASP.NET MVC web application. Users add, update, and modify images on the platform. Images are stored in Azure Blob storage.
More than one user at a time must be able to modify the same image. You need to implement optimistic concurrency for uploading images.
Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
NOTE: Each correct solution is worth one point.

• A. Mastered
• B. Not Mastered

Answer: A

Explanation:
Optimistic concurrency means allowing concurrency conflicts to happen, and then reacting appropriately if they do.
For the PUT method, If-Match can be used to prevent the lost update problem. It can check if the modification of a resource that the user wants to upload will not override another change that has been done since the original resource was fetched. If the request cannot be fulfilled, the 412 (Precondition Failed) response is returned.
