QUESTION NO:18
You need to recommend a solution to minimize the amount of time it takes to execute sp1. With what
should you recommend replacing Table1?
Case Study:
A. Datum Case B
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 Enterprise 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 updated frequently. The database is often used for reporting. 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 Table1 sequentially several times. After the
process is complete, Table1 is deleted.
A stored procedure named sp2 is used to generate a product list. The product list contains the names of
products grouped by category. Sp2 takes several minutes to run due to locks on the tables the procedure
accesses. The locks are caused by sp1 and sp3.
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 fails.
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. All nested stored procedures handle errors by using structured exception
handling.
A stored procedure named sp5 calls several stored procedures in the same database. Security checks are
performed each time sp5 calls a stored procedure.
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 Time Objective (RTO) of 5 minutes.
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 manage security for the Sales database. The
junior database administrators will not have any other administrative rights. A. Datum wants to track which
users run each stored procedure.
Storage
A. Datum has limited storage. Whenever possible, all storage space 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.
A. a table variable
B. a function
C. a view
D. a temporary table

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.
A. a temporary table
B. a function
C. a view
D. a table variable
