Microsoft Developing SQL Databases - 70-762 FREE EXAM DUMPS QUESTIONS & ANSWERS

You have a database that contains both disk-based and memory-optimized tables.
You need to create two modules. The modules must meet the requirements described in the following table.

Which programming object should you use for each module? To answer, select the appropriate object types 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?

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some questions sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You need to collect data from the following two sources:
* The performance counters of the operating system
* Microsoft SQL Server events
You must analyze the two datasets side-by side by using a single tool.
Solution: You use SQL Server Profiler and SQL Server Extended Events to collect performance data. You use SQL Server Profiler to analyze the data.
Does this meet the goal?

Your company has employees in different regions around the world.
You need to create a database table that stores the following employee attendance information:
- Employee ID
- date and time employee checked in to work
- date and time employee checked out of work
Date and time information must be time zone aware and must not store fractional seconds.
Solution: You run the following Transact-SQL statement:

Does the solution meet the goal?

You have a database that contains a table named Employees. The table stores information about the employees of your company.
You need to implement and enforce the following business rules:
* Limit the values that are accepted by the Salary column.
* Prevent salaries less than $15,000 and greater than $300,000 from being entered.
* Determine valid values by using logical expressions.
* Do not validate data integrity when running DELETE statements.
Solution: You implement a foreign key on the table.
Does the solution meet the goal?

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 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 . 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 modify the environment to meet the requirements for the Orders table.
What should you create?

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 database that contains a table named Employees. The table stores information about the employees of your company.
You need to implement the following auditing rules for the Employees table:
- Record any changes that are made to the data in the Employees table.
- Customize the data recorded by the audit operations.
Solution: You implement a check constraint on the Employees table.
Does the solution meet the goal?

Note: This question is part of a series of questions that present the same scenario. Each question in this series contains a unique solution. Determine whether the solution meets the stated goals.
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 add a unique clustered index to the Employees table.
Does the solution meet the goal?

You have a data warehouse fact table that has a clustered columnstore index.
You have multiple CSV files that contain a total of 3 million rows of data.
You need to upload the data to the fact table. The solution must avoid the delta group when you import the data.
Which solution will achieve the goal in the least amount of time?
