NEW QUESTION # 59
Drag and Drop Question
You have an Azure SQL Database named DB1.
You plan to create a table named Sales that will contain a column named Salesdate.
You need to implement table partitioning based on the Salesdate column. The solution must ensure that the lowest boundary value is included in each partition.
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: Create a partition function that uses the AS RANGE RIGHT FOR VALUES clause.
To partition an Azure SQL Database table by a sale date while including the lowest boundary value in each partition, you must use a RANGE RIGHT partition function.
Define the boundaries for your partitions using the RANGE RIGHT specification. This ensures that the boundary date itself acts as the inclusive lowest value of that partition (e.g., a boundary of
2026-01-01 starts a partition covering that day and onward).
CREATE PARTITION FUNCTION pf_SaleDate (DATE)
AS RANGE RIGHT
FOR VALUES ('2026-01-01', '2026-02-01', '2026-03-01');
Step 2: Create a partition scheme
Create Partition Scheme
Map the partition function to the storage destinations. In Azure SQL Database, all partitions must be mapped to the [PRIMARY] filegroup because custom filegroups are not supported.
CREATE PARTITION SCHEME ps_SaleDate
AS PARTITION pf_SaleDate
ALL TO ([PRIMARY]);
Step 3: Create a table
Create Table on Partition Scheme
Create the table and assign the partition scheme to the sale date column instead of a traditional filegroup specification.
CREATE TABLE Sales (
SaleID INT IDENTITY(1,1),
SaleDate DATE NOT NULL,
Amount DECIMAL(18,2),
CustomerID INT,
-- The partitioning column must be part of the primary key if enforced
CONSTRAINT PK_Sales PRIMARY KEY CLUSTERED (SaleID, SaleDate)
)
ON ps_SaleDate (SaleDate);

NEW QUESTION # 60
You have an Azure SQL database named DB3.
You need to provide a user named DevUser with the ability to view the properties of DB3 from Microsoft SQL Server Management Studio (SSMS) as shown in the exhibit. (Click the Exhibit tab.)
Which Transact-SQL command should you run?
Answer: C
Explanation:
The exhibits displays Database [State] properties.
To query a dynamic management view or function requires SELECT permission on object and VIEW SERVER STATE or VIEW DATABASE STATE permission.
Reference:
https://docs.microsoft.com/en-us/sql/relational-databases/databases/database-properties-options-page Basic Concept: This question tests monitor, configure, and optimize database resources in the DP-300 exam context. The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
Why C is Correct: GRANT VIEW DATABASE STATE TO DevUser is correct because it is the feature whose normal purpose matches the stated requirement. GRANT VIEW DATABASE STATE TO DevUser 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. The scenario wording points to that specific behavior: You need to provide a user named DevUser with the ability to view the properties of DB3 from Microsoft SQL Server Management Studio (SSMS) as shown in the exhibit.
Why A is Wrong: GRANT SHOWPLAN TO DevUser 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 B is Wrong: GRANT VIEW DEFINITION TO DevUser 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.
Why D is Wrong: GRANT SELECT TO DevUser 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.
NEW QUESTION # 61

NEW QUESTION # 62
You have an Azure SQL database. The database contains a table that uses a columnstore index and is accessed infrequently.
You enable columnstore archival compression.
What are two possible results of the configuration? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
Answer: B,D
Explanation:
Section: [none]
Explanation:
For rowstore tables and indexes, use the data compression feature to help reduce the size of the database. In addition to saving space, data compression can help improve performance of I/O intensive workloads because the data is stored in fewer pages and queries need to read fewer pages from disk.
Use columnstore archival compression to further reduce the data size for situations when you can afford extra time and CPU resources to store and retrieve the data.
