Microsoft 070-762 Actual Tests : Developing SQL Databases

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 named DB1 that contains the following tables: Customer, CustomerToAccountBridge, and CustomerDetails. The three tables are part of the Sales schema. The database also contains a schema named Website. You create the Customer table by running the following Transact-SQL statement:

The value of the CustomerStatus column is equal to one for active customers. The value of the Account1Status and Account2Status columns are equal to one for active accounts. The following table displays selected columns and rows from the Customer table.

You plan to create a view named Website.Customer and a view named Sales.FemaleCustomers.
Website.Customer must meet the following requirements:
* Allow users access to the CustomerName and CustomerNumber columns for active customers.
* Allow changes to the columns that the view references. Modified data must be visible through the view.
* Prevent the view from being published as part of Microsoft SQL Server replication.
Sales.Female.Customers must meet the following requirements:
* Allow users access to the CustomerName, Address, City, State and PostalCode columns.
* Prevent changes to the columns that the view references.
* Only allow updates through the views that adhere to the view filter.
You have the following stored procedures: spDeleteCustAcctRelationship and spUpdateCustomerSummary.
The spUpdateCustomerSummary stored procedure was created by running the following Transacr-SQL statement:

You run the spUpdateCustomerSummary stored procedure to make changes to customer account summaries.
Other stored procedures call the spDeleteCustAcctRelationship to delete records from the CustomerToAccountBridge table.
You must update the design of the Customer table to meet the following requirements.
* You must be able to store up to 50 accounts for each customer.
* Users must be able to retrieve customer information by supplying an account number.
* Users must be able to retrieve an account number by supplying customer information.
You need to implement the design changes while minimizing data redundancy.
What should you do?

• A. Split the table into three separate tables. Include the AccountNumber and CustomerID columns in the first table. Include the CustomerName and Gender columns in the second table. Include the AccountStatus column in the third table.
• B. Split the table into two separate tables, Include the CustomerID and AccountNumber columns in the first table. Include the AccountNumber, AccountStatus, CustomerName and Gender columns in the second table.
• C. Split the table into two separate tables. Include AccountNumber, CustomerID, CustomerName and Gender columns in the first table. Include the AccountNumber and AccountStatus columns in the second table.
• D. Split the table into two separate tables, Include the CustomerID, CustomerName and Gender columns in the first table. IncludeAccountNumber, AccountStatus and CustomerID columns in the second table.

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 create the Sales Order table
How should you complete the table definition? To answer? select the appropriate Transact-SQL segments in the answer area.

Explanation

Box 1: NONCLUSTERED HASHWITH (BUCKET_COUNT = 10000000)
Hash index is preferable over a nonclustered index when queries test the indexed columns by use of a WHERE clause with an exact equality on all index key columns. We should use a bucket count of 10 million.
Box 2: SCHEMA_ONLY
Durability: The value of SCHEMA_AND_DATA indicates that the table is durable, meaning that changes are persisted on disk and survive restart or failover. SCHEMA_AND_DATA is the default value.
The value of SCHEMA_ONLY indicates that the table is non-durable. The table schema is persisted but any data updates are not persisted upon a restart or failover of the database. DURABILITY=SCHEMA_ONLY is only allowed with MEMORY_OPTIMIZED=ON.

You are creating the following two stored procedures:
* A natively-compiled stored procedure
* An interpreted stored procedure that accesses both disk-based and memory-optimized tables Both stored procedures run within transactions.
You need to ensure that cross-container transactions are possible.
Which setting or option should you use?

• A. the SET MEMORY_OPTIMIZED_ELEVATE_TO_SNAPSHOT=OFF option for the database
• B. the SERIALIZABLE table hint on disk-based tables
• C. the SET TRANSACTION_READ_COMMITTED isolation level for the connection
• D. the SET MEMORY_OPTIMIZED_ELEVATE_TO_SNAPSHOT=ON option for the database

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 stored 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 stored procedure on the Employees table.
Does the solution meet the goal?

• A. No
• B. Yes
