NEW QUESTION # 338
You have SQL Server on Azure virtual machines in an availability group.
You have a database named DB1 that is NOT in the availability group.
You create a full database backup of DB1.
You need to add DB1 to the availability group.
Which restore option should you use on the secondary replica?
Answer: B
Explanation:
Prepare a secondary database for an Always On availability group requires two steps:
1. Restore a recent database backup of the primary database and subsequent log backups onto each server
instance that hosts the secondary replica, using RESTORE WITH NORECOVERY
2. Join the restored database to the availability group.

NEW QUESTION # 339
You have an Azure key vault named Vault1 and a SQL Server on Azure Virtual Machines instance named SQL1 SQL 1 hosts a database named DB1.
You need to configure Transparent Data Encryption (TDE) on D61 to use a key in Vault1 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.
Answer:
Explanation:
1 - Create an Azure AD service principal and grant the service principal permission for Vault1.
2 - On SQL1, create an asymmetric key.
3 - On SQL1, create a cryptographic provider and a Microsoft SQL Server credential.
4 - On SQL1, create a login from the asymmetric key.
NEW QUESTION # 340
You have 50 Azure SQL databases.
You need to notify the database owner when the database settings, such as the database size and pricing tier, are modified in Azure.
What should you do?
Answer: D
Explanation:
Activity log events - An alert can trigger on every event, or, only when a certain number of events occur.
Reference:
https://docs.microsoft.com/en-us/azure/azure-sql/database/alerts-insights-configure-portal Basic Concept: This question tests Azure monitoring and performance management, including which metric, log destination, or alerting behavior fits the operational requirement.
Why D is Correct: Create an alert rule that uses an Activity Log signal type. is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait
/blocking detail, or automatic remediation. In this scenario, the important constraint is: You need to notify the database owner when the database settings, such as the database size and pricing tier, are modified in Azure.
Create an alert rule that uses an Activity Log signal type. satisfies that constraint without adding an unrelated service or manual process.
Why A is Wrong: Create a diagnostic setting for the activity log that has the Security log enabled. is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait/blocking detail, or automatic remediation. It is useful in other troubleshooting paths, but this scenario requires a more specific monitoring or optimization feature.
Why B is Wrong: For the database, create a diagnostic setting that has the InstanceAndAppAdvanced metric enabled. is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait/blocking detail, or automatic remediation. It would produce a different operational signal than the one needed to investigate, alert, or tune the workload in this question.
Why C is Wrong: Create an alert rule that uses a Metric signal type. is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait/blocking detail, or automatic remediation. It does not expose the required metric, query history, wait/blocking signal, or tuning mechanism; using it would not give the administrator the evidence requested.
NEW QUESTION # 341
You are building a database in an Azure Synapse Analytics serverless SQL pool.
You have data stored in Parquet files in an Azure Data Lake Storage Gen2 container.
Records are structured as shown in the following sample.
The records contain two applicants at most.
You need to build a table that includes only the address fields.
How should you complete the Transact-SQL statement? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: CREATE EXTERNAL TABLE
An external table points to data located in Hadoop, Azure Storage blob, or Azure Data Lake Storage. External tables are used to read data from files or write data to files in Azure Storage. With Synapse SQL, you can use external tables to read external data using dedicated SQL pool or serverless SQL pool.
Syntax:
CREATE EXTERNAL TABLE { database_name.schema_name.table_name | schema_name.table_name | table_name } ( < column_definition > [ ,...n ] ) WITH ( LOCATION = ' folder_or_filepath ' , DATA_SOURCE = external_data_source_name, FILE_FORMAT = external_file_format_name Box 2. OPENROWSET When using serverless SQL pool, CETAS is used to create an external table and export query results to Azure Storage Blob or Azure Data Lake Storage Gen2.
Example:
AS
SELECT decennialTime, stateName, SUM(population) AS population
FROM
OPENROWSET(BULK ' https://azureopendatastorage.blob.core.windows.net/censusdatacontainer/release
/us_population_county/year=*/*.parquet ' ,
FORMAT= ' PARQUET ' ) AS [r]
GROUP BY decennialTime, stateName
GO
