QUESTION 39
You have a database named DB1.
You plan to create a stored procedure that will insert rows into three different tables.
Each insert must use the same identifying value for each table, but the value must increase from one invocation of the stored procedure to the next.
Occasionally, the identifying value must be reset to its initial value.
You need to design a mechanism to hold the identifying values for the stored procedure to use. What should you do? More than one answer choice may achieve the goal. Select the BEST answer.

A.    Create a sequence object that holds the next value in the sequence.
Retrieve the next value by using the stored procedure.
Reset the value by using an ALTER SEQUENCE statement as needed.
B.    Create a fourth table that holds the next value in the sequence.
At the end each transaction, update the value by using the stored procedure.
Reset the value as needed by using an UPDATE statement.
C.    Create a sequence object that holds the next value in the sequence.
Retrieve the next value by using the stored procedure.
Increment the sequence object to the next value by using an ALTER SEQUENCE statement.
Reset the value as needed by using a different ALTER SEQUENCE statement.
D.    Create an identity column in each of the three tables.
Use the same seed and the same increment for each table.
Insert new rows into the tables by using the stored procedure.
Use the DBCC CHECKIDENT command to reset the columns as needed.

Case Study 1 – A. Datum (QUESTION 40 ~ QUESTION 46)
Overview
General Overview
A.Datum Corporation has offices in Miami and Montreal.
The network contains a single Active Directory forest named adatum.com.
The offices connect to each other by using a WAN link that has a 5-ms latency.
A.Datum standardizes its database platform by using SQL Server 2012 Standard edition.
Databases
Each office contains databases named Sales, Inventory, Customers, Products, Personnel, and Dev.
Servers and databases are managed by a team of database administrators. Currently, all of the database administrators have the same level of permissions on all of the servers and all of the databases.
The Customers database contains two tables named Customers and Classifications.
The following graphic shows the relevant portions of the tables:

The following table shows the current data in the Classifications table:

The Inventory database is used mainly for reports. The database is recreated every day.
A full backup of the database currently takes three hours to complete.
Stored Procedures
A stored procedure named sp1 generates millions of rows of data for multiple reports.
Sp1 combines data from five different tables from the Sales and Customers databases in a table named Table1.
After Table1 is created, the reporting process reads data from a table in the Products database and searches for information in Table1 based on input from the Products table. After the process is complete, Table1 is deleted.
A stored procedure named sp2 is used to generate a product list. Sp2 takes several minutes to run due to locks on the tables the procedure accesses. A stored procedure named sp3 is used to update prices. Sp3 is composed of several UPDATE statements called in sequence from within a transaction. Currently, if one of the UPDATE statements fails, the stored procedure continues to execute.
A stored procedure named sp4 calls stored procedures in the Sales, Customers, and Inventory databases. The nested stored procedures read tables from the Sales, Customers, and Inventory databases. Sp4 uses an EXECUTE AS clause.
A stored procedure named sp5 changes data in multiple databases.
Security checks are performed each time sp5 accesses a database.
You suspect that the security checks are slowing down the performance of sp5.
All stored procedures accessed by user applications call nested stored procedures.
The nested stored procedures are never called directly.
Design Requirements
Data Recovery
You must be able to recover data from the Inventory database if a storage failure occurs.
You have a Recovery Point Objective (RPO) of one hour.
You must be able to recover data from the Dev database if data is lost accidentally.
You have a Recovery Point Objective (RPO) of one day.
Classification Changes
You plan to change the way customers are classified.
The new classifications will have four levels based on the number of orders.
Classifications may be removed or added in the future.
Management requests that historical data be maintained for the previous classifications.
Security
A group of junior database administrators must be able to view the server state of the SQL Server instance that hosts the Sales database. The junior database administrators will not have any other administrative rights.
Storage
A. Datum has limited storage. Whenever possible, all storagespace should be minimized for all databases and all backups.
Error Handling
There is currently no error handling code in any stored procedure.
You plan to log errors in called stored procedures and nested stored procedures.
Nested stored procedures are never called directly.

QUESTION 40
You need to recommend a solution for the planned changes to the customer classifications.
What should you recommend? (Each correct answer presents part of the solution. Choose all that apply.)

A.    Add a table to track any changes made to the classification of each customer.
B.    Add columns for each classification to the Customers table.
C.    Implement change data capture.
D.    Add a row to the Customers table each time a classification changes.
E.    Add a column to the Classifications table to track the status of each classification.

Answer: AE
Explanation:
* scenario:
You plan to change the way customers are classified. The new classifications will have four levels based on the number of orders. Classifications may be removed or added in the future.
Incorrect:
Not E: Change data capture provides information about DML changes on a table and a database. By using change data capture, you eliminate expensive techniques such as user triggers, timestamp columns, and join queries.
