A recent failure causes the master database to be lost.
You discover that all Microsoft SQL Server integration Services (SSIS) packages fail to run on the virtual
machine.

Answer:
Explanation:
Section: [none]
Explanation:
Step 1: Attach the SSISDB database
Step 2: Turn on the TRUSTWORTHY property and the CLR property
If you are restoring the SSISDB database to an SQL Server instance where the SSISDB catalog was never
created, enable common language runtime (clr)
Step 3: Open the master key for the SSISDB database
Restore the master key by this method if you have the original password that was used to create SSISDB.
open master key decryption by password = 'LS1Setup!' --'Password used when creating SSISDB'
Alter Master Key Add encryption by Service Master Key
Step 4: Encrypt a copy of the mater key by using the service master key

You need to identify the cause of the performance issues on SalesSQLDb1.
Which two dynamic management views should you use? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
- A. sys.dm_exec_compute_node_errors
- B. sys.dm_cdc_errors
- C. sys.dm_exec_requests
- D. sys.dm_pdw_nodes_tran_locks
- E. sys.dm_pdw_nodes_os_wait_stats
- F. sys.dm_tran_locks
Answer: D,E
Explanation:
Section: [none]
Explanation:
SalesSQLDb1 experiences performance issues that are likely due to out-of-date statistics and frequent blocking queries.
A: Use sys.dm_pdw_nodes_tran_locks instead of sys.dm_tran_locks from Azure Synapse Analytics (SQL Data Warehouse) or Parallel Data Warehouse.
E: Example:
The following query will show blocking information.
SELECT
t1.resource_type,
t1.resource_database_id,
t1.resource_associated_entity_id,
t1.request_mode,
t1.request_session_id,
t2.blocking_session_id
FROM sys.dm_tran_locks as t1
INNER JOIN sys.dm_os_waiting_tasks as t2
ON t1.lock_owner_address = t2.resource_address;
Note: Depending on the system you're working with you can access these wait statistics from one of three locations:
sys.dm_os_wait_stats: for SQL Server
sys.dm_db_wait_stats: for Azure SQL Database
sys.dm_pdw_nodes_os_wait_stats: for Azure SQL Data Warehouse
Incorrect Answers:
F: sys.dm_tran_locks returns information about currently active lock manager resources in SQL Server 2019 (15.x). Each row represents a currently active request to the lock manager for a lock that has been granted or is waiting to be granted.
Instead use sys.dm_pdw_nodes_tran_locks.

NEW QUESTION # 87
You have a new Azure SQL database. The database contains a column that stores confidential information.
You need to track each time values from the column are returned in a query. The tracking information must be stored for 365 days from the date the query was executed.
Which three actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
- A. Turn on auditing and write audit logs to an Azure Storage account.
- B. Turn on Advanced Data Security for the Azure SQL server.
- C. Add extended properties to the column.
- D. Turn on Azure Advanced Threat Protection (ATP).
- E. Apply sensitivity labels named Highly Confidential to the column.
Answer: A,B,E
Explanation:
Explanation
C: Advanced Data Security (ADS) is a unified package for advanced SQL security capabilities. ADS is available for Azure SQL Database, Azure SQL Managed Instance, and Azure Synapse Analytics. It includes functionality for discovering and classifying sensitive data D: You can apply sensitivity-classification labels persistently to columns by using new metadata attributes that have been added to the SQL Server database engine. This metadata can then be used for advanced, sensitivity-based auditing and protection scenarios.
A: An important aspect of the information-protection paradigm is the ability to monitor access to sensitive data. Azure SQL Auditing has been enhanced to include a new field in the audit log called data_sensitivity_information. This field logs the sensitivity classifications (labels) of the data that was returned by a query. Here's an example:

NEW QUESTION # 88
You have an Azure Synapse Analytics workspace named WS1 that contains an Apache Spark pool named Pool1.
You plan to create a database named DB1 in Pool1.
You need to ensure that when tables are created in DB1, the tables are available automatically as external tables to the built-in serverless SQL pool.
Which format should you use for the tables in DB1?
- A. JSON
- B. CSV
- C. ORC
- D. Parquet
Answer: D
Explanation:
Section: [none]
Explanation:
Serverless SQL pool can automatically synchronize metadata from Apache Spark. A serverless SQL pool database will be created for each database existing in serverless Apache Spark pools.
For each Spark external table based on Parquet and located in Azure Storage, an external table is created in a serverless SQL pool database. As such, you can shut down your Spark pools and still query Spark external tables from serverless SQL pool.

NEW QUESTION # 89
You have a version-8.0 Azure Database for MySQL database.
You need to identify which database queries consume the most resources.
Which tool should you use?
- A. Metrics
- B. Alerts
- C. Query Store
- D. Query Performance Insight
Answer: C
Explanation:
The Query Store feature in Azure Database for MySQL provides a way to track query performance over time.
Query Store simplifies performance troubleshooting by helping you quickly find the longest running and most resource-intensive queries. Query Store automatically captures a history of queries and runtime statistics, and it retains them for your review. It separates data by time windows so that you can see database usage patterns.
Data for all users, databases, and queries is stored in the mysql schema database in the Azure Database for MySQL instance.

NEW QUESTION # 93
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. an actual execution plan
- B. an estimated execution plan
- C. Live Query Statistics
- D. Client Statistics
Answer: A
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.
