NEW QUESTION 34
Your company uses Azure Stream Analytics to monitor devices.
The company plans to double the number of devices that are monitored.
You need to monitor a Stream Analytics job to ensure that there are enough processing resources to handle the additional load.
Which metric should you monitor?
- A. Early Input Events
- B. Late Input Events
- C. Watermark delay
- D. Input Deserialization Errors
Answer: C
Explanation:
The Watermark delay metric is computed as the wall clock time of the processing node minus the largest watermark it has seen so far.
The watermark delay metric can rise due to:
1. Not enough processing resources in Stream Analytics to handle the volume of input events.
2. Not enough throughput within the input event brokers, so they are throttled.
3. Output sinks are not provisioned with enough capacity, so they are throttled.

You plan to deploy additional instances of App1 to separate Azure regions. Each region will have a separate instance of App1 and DB1. The separate instances of DB1 will sync by using Azure SQL Data Sync.
You need to recommend a database service for the deployment. The solution must minimize administrative effort.
What should you include in the recommendation?
- A. SQL Server on Azure virtual machines
- B. Azure SQL Managed instance
- C. Azure SQL Database single database

NEW QUESTION 36
You need to trigger an Azure Data Factory pipeline when a file arrives in an Azure Data Lake Storage Gen2 container.
Which resource provider should you enable?
- A. Microsoft.EventGrid
- B. Microsoft.Automation
- C. Microsoft.EventHub
- D. Microsoft.Sql
Answer: A
Explanation:
Section: [none]
Explanation:
Event-driven architecture (EDA) is a common data integration pattern that involves production, detection, consumption, and reaction to events. Data integration scenarios often require Data Factory customers to trigger pipelines based on events happening in storage account, such as the arrival or deletion of a file in Azure Blob Storage account. Data Factory natively integrates with Azure Event Grid, which lets you trigger pipelines on such events.

You need to ensure that dbadmin1 receives an email alert if a job fails.
Which three 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.
Answer:
Explanation:
Explanation:
Step 1: Enable the email settings for the SQL Server Agent.

Step 2: Create a job alert
Step 3: Create a job notification
Example:
-- adds an e-mail notification for the specified alert (Test Alert)
-- This example assumes that Test Alert already exists
-- and that Francois Ajenstat is a valid operator name.
USE msdb ;
GO
EXEC dbo.sp_add_notification
@alert_name = N'Test Alert',
@operator_name = N'Francois Ajenstat',
@notification_method = 1 ;

You need to apply 20 built-in Azure Policy definitions to all new and existing Azure SQL Database deployments in an Azure subscription. The solution must minimize administrative effort.
Which three 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.
Select and Place:
Answer:
Explanation:
Section: [none]
Explanation:
Step 1: Create an Azure Policy Initiative
The first step in enforcing compliance with Azure Policy is to assign a policy definition. A policy definition defines under what condition a policy is enforced and what effect to take.
With an initiative definition, you can group several policy definitions to achieve one overarching goal. An initiative evaluates resources within scope of the assignment for compliance to the included policies.
Step 2: Create an Azure Policy Initiative assignment
Assign the initiative definition you created in the previous step.
Step 3: Run Azure Policy remediation tasks
To apply the Policy Initiative to the existing SQL databases.

NEW QUESTION 39
You have an Azure SQL database.
You identify a long running query.
You need to identify which operation in the query is causing the performance issue.
What should you use to display the query execution plan in Microsoft SQL Server Management Studio (SSMS)?
- A. Live Query Statistics
- B. Client Statistics
- C. an actual execution plan
- D. an estimated execution plan
Answer: C
Explanation:
Section: [none]
Explanation:
To include an execution plan for a query during execution
1. On the SQL Server Management Studio toolbar, click Database Engine Query. You can also open an existing query and display the estimated execution plan by clicking the Open File toolbar button and locating the existing query.
2. Enter the query for which you would like to display the actual execution plan.
3. On the Query menu, click Include Actual Execution Plan or click the Include Actual Execution Plan toolbar button.
Note: Actual execution plans are generated after the Transact-SQL queries or batches execute. Because of this, an actual execution plan contains runtime information, such as actual resource usage metrics and runtime warnings (if any). The execution plan that is generated displays the actual query execution plan that the SQL Server Database Engine used to execute the queries.

NEW QUESTION 40
You have SQL Server on an Azure virtual machine that contains a database named DB1.
The database reports a CHECKSUM error.
You need to recover the database.
How should you complete the statements? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: SINGLE_USER
The specified database must be in single-user mode to use one of the following repair options.
Box 2: REPAIR_ALLOW_DATA_LOSS
REPAIR_ALLOW_DATA_LOSS tries to repair all reported errors. These repairs can cause some data loss.
Note: The REPAIR_ALLOW_DATA_LOSS option is a supported feature but it may not always be the best option for bringing a database to a physically consistent state. If successful, the REPAIR_ALLOW_DATA_LOSS option may result in some data loss. In fact, it may result in more data lost than if a user were to restore the database from the last known good backup.
Incorrect Answers:
REPAIR_FAST
Maintains syntax for backward compatibility only. No repair actions are performed.
Box 3: MULTI_USER
MULTI_USER
All users that have the appropriate permissions to connect to the database are allowed.
