NEW QUESTION 1
You have implemented code that uses elastic transactions spanning across three different Azure SQL Database logical servers. Database administrators report that some transactions take longer to complete than expected.
You need to use the correct tool to monitor all the transactions originating from the elastic transaction implementation. Which tool should you use?

• A. Run the sys.dm_tran_active_transactions dynamic management view.
• B. Run the sys.dm_tran_current_snapshot dynamic management view.
• C. Run the sys.dm_tran_active_snapshot_database_transactions dynamic management
• D. Use the dependencies section of Azure Applications Insights.

Answer: A

Explanation: Use Dynamic Management Views (DMVs) in SQL DB to monitor status and progress of your ongoing elastic database transactions.
These DMVs are particularly useful:
sys.dm_tran_active_transactions: Lists currently active transactions and their status. The UOW (Unit Of Work) column can identify the different child transactions that belong to the same distributed transaction. All transactions within the same distributed transaction carry the same UOW value.
sys.dm_tran_database_transactions: Provides additional information about transactions, such as placement of the transaction in the log.
sys.dm_tran_locks: Provides information about the locks that are currently held by ongoing transactions References:

Alert users about promotions at local restaurants.
Enable users to place an order for delivery or pickup by using their voice.
Greet the user upon sigh-in by displaying a graphical interface that contains action buttons.
The chatbot greeting interface must match the formatting of the following example:

Vendor API
Vendors receive and provide updates for the restaurant inventory and delivery services by using Azure API Management hosted APIs. Each vendor uses their own subscription to access each of the APIs.
APIs must meet the following conditions:
API usage must not exceed 5,000 calls and 50,000 kilobytes of bandwidth per hour per vendor.
If a vendor is nearing the number of calls or bandwidth limit, the API must trigger email notifications to the vendor.
APIs must prevent API usage spikes on a per-subscription basis by limiting the call rate to 100 calls per minute.
The Inventory API must be written by using ASP.NET Core and Node.js.
The API must be updated to provide an interface to Azure SQL Database. Database objects must be managed by using code.
The Delivery API must be protected by using the OAuth 2.0 protocol with Azure Active Directory (Azure AD) when called from the Azure web app. You register the Delivery API and web app in Azure AD. You enable OAuth 2.0 in the web app.
The delivery API must update the Products table, the Vendor transactions table, and the Billing table in a single transaction.

NEW QUESTION 12
A construction company creates three-dimensional models from photographs and design diagrams of buildings. The company plans to store high-resolution photographs and blueprint files in Azure Blob Storage. The files are currently stored in the construction company’s office.
You are developing a tool to connect to Azure Storage, create container, and then upload the files. The tool must remain responsive to the end user while it is running and performing remote I/O operations. It must also wait for methods to complete before continuing.
You need to complete the configuration.
How should you complete the code? To answer, select the appropriate options in the answer area. NOTE: Each correct solution is worth one point.

Answer:

Explanation: Box 1: ProcessAsync();
Box 2: await cloudBlobContainer.CreatAsync();
If you specify that a method is an async method by using the async modifier, you enable the following two capabilities.
The marked async method can use await to designate suspension points. The await operator tells the compiler that the async method can't continue past that point until the awaited asynchronous process is complete. In the meantime, control returns to the caller of the async method.
The suspension of an async method at an await expression doesn't constitute an exit from the method, and finally blocks don’t run.
The marked async method can itself be awaited by methods that call it. References:
