Microsoft Developing SQL Databases - 070-762 FREE EXAM DUMPS QUESTIONS & ANSWERS

Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
You have a database that contains the following tables: BlogCategory, BlogEntry, ProductReview, Product, and SalesPerson. The tables were created using the following Transact SQL statements:

You must modify the ProductReview Table to meet the following requirements:
* The table must reference the ProductID column in the Product table
* Existing records in the ProductReview table must not be validated with the Product table.
* Deleting records in the Product table must not be allowed if records are referenced by the ProductReview table.
* Changes to records in the Product table must propagate to the ProductReview table.
You also have the following database tables: Order, ProductTypes, and SalesHistory, The transact-SQL statements for these tables are not available.
You must modify the Orders table to meet the following requirements:
* Create new rows in the table without granting INSERT permissions to the table.
* Notify the sales person who places an order whether or not the order was completed.
You must add the following constraints to the SalesHistory table:
* a constraint on the SaleID column that allows the field to be used as a record identifier
* a constant that uses the ProductID column to reference the Product column of the ProductTypes table
* a constraint on the CategoryID column that allows one row with a null value in the column
* a constraint that limits the SalePrice column to values greater than four Finance department users must be able to retrieve data from the SalesHistory table for sales persons where the value of the SalesYTD column is above a certain threshold.
You plan to create a memory-optimized table named SalesOrder. The table must meet the following requirements:
* The table must hold 10 million unique sales orders.
* The table must use checkpoints to minimize I/O operations and must not use transaction logging.
* Data loss is acceptable.
Performance for queries against the SalesOrder table that use Where clauses with exact equality operations must be optimized.
You need to enable referential integrity for the ProductReview table.
How should you complete the relevant Transact-SQL statement? To answer? select the appropriate Transact-SQL segments in the answer area.

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution. Determine whether the solution meets the stated goals.
You have a table that has a clustered index and a nonclustered index. The indexes use different columns from the table. You have a query named Query1 that uses the nonclustered index.
Users report that Query1 takes a long time to report results. You run Query1 and review the following statistics for an index seek operation:

You need to resolve the performance issue. Solution:
You drop the nonclustered index.
Does the solution meet the goal?

You are developing a new application that uses a stored procedure. The stored procedure inserts thousands of records as a single batch into the Employees table.
Users report that the application response time has worsened since the stored procedure was updated. You examine disk-related performance counters for the Microsoft SQL Server instance and observe several high values that include a disk performance issue. You examine wait statistics and observe an unusually high WRITELOG value.
You need to improve the application response time.
Solution: You update the application to use implicit transactions when connecting to the database.
Does the solution meet the goal?

You have a Microsoft Azure SQL Database named MyDb that uses server version V12.
You plan to use Query Performance Insight to troubleshoot performance problems. The database query store is not enabled.
You need to enable the database query store to meet the following requirements for the database:
- Statistics must be aggregated every 15 minutes.
- Query stores must use no more than 1,024 megabytes (MB) of storage.
- Query information must be retained for at least 15 days.
- Queries must be captured based on resource consumption.
You connect to the database by using SQL Server Managements Studio.
How should you complete the Transact-SQL statements? To answer, drag the appropriate Transact-SQL segments to the correct locations. Each Transact-SQL segment may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: More than one combination of answer choices is correct. You will receive credit for any of the correct combinations you select. Each correct selection is worth one point.

You must troubleshoot performance issues that users report. You identify the following representative user sessions:

You need to configure the appropriate Extended Events.
Which target should you use for each session? To answer, drag the appropriate Extended Event targets to the correct sessions. Each Extended Event target may be used once, or not at all. You may need to drag the split bar between panes or scroll to view content.

You need to create a stored procedure named spDeleteCategory to delete records in the database. The stored procedure must meet the following requirements:
* Delete records in both the BlogEntry and BlogCategory tables where CategoryId equals parameter
@CategoryId.
* Avoid locking the entire table when deleting records from the BlogCategory table.
* If an error occurs during a delete operation on either table, all changes must be rolled back, otherwise all changes should be committed.
How should you complete the procedure? To answer, select the appropriate Transact-SQL segments in the answer area.

You are a database developer for a company. The company has a server that has multiple physical disks. The disks are not part of a RAID array. The server hosts three Microsoft SQL Server instances. There are many SQL jobs that run during off-peak hours.
You observe that many deadlocks appear to be happening during specific times of the day.
You need to monitor the SQL environment and capture the information about the processes that are causing the deadlocks.

You have a database named DB1 that includes a table named Sales-Orders.
You grant a user named User1 select permissions on the sales schema.
You need to ensure that User1 can select data from the sales .orders table without specifying the schema name in any Transact-SQL statements.
Solution: You create a stored procedure in the sales schema that selects the data from the sales. orders table.

You are developing an application to track customer sales. You create tables to support the application. You need to create a database object that meets the following data entry requirements:

What should you create?

You are developing a database reporting solution for a table that contains 900 million rows and is 103 GB.
The table is updated thousands of times a day, but data is not deleted.
The SELECT statements vary in the number of columns used and the amount of rows retrieved.
You need to reduce the amount of time it takes to retrieve data from the table. The must prevent data duplication.
Which indexing strategy should you use?

You are designing a solution for a company that operates retail stores. Each store has a database that tracks sales transactions. You create a summary table in the database at the corporate office. You plan to use the table to record the quantity of each product sold at each store on each day. Managers will use this data to identify reorder levels for products.
Every evening, stores must transmit sales data to the corporate office. The data must be inserted into the summary table that includes the storeID, Production. Qtysold. Totprodsales, and Datesold columns.
You need to prevent duplicate rows in the summary table. Each row must uniquely identify the store that sold the product and the total amount sold for that store on a specific date.
What should you include in your solution?

You have a database with multiple tables. You must insert data into the tables by using views.
Which of the following two statements best describes an updatable view?
NOTE: Each correct selection is worth one point.

You run the following query:

The following image displays the execution plan the query optimizer generates for this query:

Users frequently run the same query with different values for the local variable @lastName. The table named Person is persisted on disk.
You need to create an index on the Person.Person table that meets the following requirements:
- All users must be able to benefit from the index.
