Topic 2, Leafield Solutions
General Overview
You are the Senior Database Administrator (DBA) for a software development company named
Leafield Solutions.
The company develops software applications custom designed to meet customer requirements.
Requirements
Leafield Solutions has been asked by a customer to develop a web-based Enterprise Resource
Planning and Management application. The new application will eventually replace a desktop
application that the customer is currently using. The current application will remain in use while the
users are trained to use the new web-based application.
You need to design the SQL Server and database infrastructure for the web-based application.
Databases
You plan to implement databases named Customers, Sales, Products, Current_Inventory, and
TempReporting.
The Sales database contains a table named OrderTotals and a table named SalesInfo. A stored
procedure named SPUpdateSalesInfo reads data in the OrderTotals table and modifies data in the
SalesInfo table. The stored procedure then reads data in the OrderTotals table a second time and
makes further changes to the information in the SalesInfo table.
The Current_Inventory database contains a large table named Inv_Current. The Inv_Current table
has a clustered index for the primary key and a nonclustered index. The primary key column uses
the identity property. The data in the Inv_Current table is over 120GB in size. The tables in the
Current_Inventory database are accessed by multiple queries in the Sales database. Another
table in the Current_Inventory database contains a self-join with an unlimited number of
hierarchies. This table is modified by a stored procedure named SPUpdate2. An external
application named ExternalApp1 will periodically query the Current_Inventory database to
generate statistical information.
The TempReporting database contains a single table named GenInfo. A stored procedure named
SPUPdateGenInfo combines data from multiple databases and generates millions of rows of data
in the GenInfo table. The GenInfo table is used for reports. When the information in GenInfo is
generated, a reporting process reads data from the Inv_Current table and queries information in
the GenInfo table based on that data. The GenInfo table is deleted after the reporting process
completes.
The Products database contains tables named ProductNames and ProductTypes.

Current System
The current desktop application uses data stored in a SQL Server 2005 database named
DesABCopAppDB. This database will remain online and data from the Current_Inventory
database will be copied to it as soon as data is changed in the Current_Inventory database.
SQL Servers
A new SQL Server 2012 instance will be deployed to host the databases for the new system. The
databases will be hosted on a Storage Area Network (SAN) that provides highly available storage.
Design Requirements
Your SQL Server infrastructure and database design must meet the following requirements:
Confidential information in the Current_ Inventory database that is accessed by ExternalApp1
must be securely stored.
Direct access to database tables by developers or applications must be denied.
The account used to generate reports must have restrictions on the hours when it is allowed to
make a connection.
Deadlocks must be analyzed with the use of Deadlock Graphs.
In the event of a SQL Server failure, the databases must remain available.
Software licensing and database storage costs must be minimized.
Development effort must be minimized.
The Tempdb databases must be monitored for insufficient free space.
Failed authentication requests must be logged.
Every time a new row is added to the ProductTypes table in the Products database, a userdefined function that validates the row must be called before the row is added to the table.
When SPUpdateSalesInfo queries data in the OrderTotals table the first time, the same rows
must be returned along with any newly added rows when SPUpdateSalesInfo queries data in the
OrderTotals table the second time.
*****************************************************************

You need to recommend a solution to meet the design requirement of logging all failed
authentication requests.
What should you recommend?

You need to recommend a monitoring solution for the Tempdb databases.
What should you recommend?

You work as a Systems Administrator at a company named ABC.com. You are in the
process of deploying new servers running SQL Server 2012.
You need to implement a highly available solution. You need to ensure that the databases
remain online in the event of a single server failure.
You are evaluating the server requirements for AlwaysOn with automatic failover and
mirroring with automatic failover.
What is the minimum number of servers required for each solution? (Choose two).

encountered on ABC-SQL1 by threads that execute.
How can you generate a report to display the most frequent wait types that occur on ABC

SQL1?

You work as a Systems Administrator at a company named ABC.com. You are in the
process of deploying new servers running SQL Server 2012.
You install a new server named ABC-SQL07. A week later, you receive reports of poor
database performance. You discover that at the times of poor performance, the CPU is
running at nearly 100% utilization.
You need to recommend a monitoring solution for ABC-SQL07 that will send you an email
alert if the CPU utilization is more than 80%.
What should you include in your recommendation?

provide the fastest possible access to the most recent orders. Historical orders can be
stored using a slower storage solution.
How can you achieve this goal?

usernames and passwords in a SQL Server 2012 database named CorpCRMDB1.
You need to ensure the usernames and passwords are secure.
Which of the following would be most suitable password storage solution?

You work as a Database Administrator (DBA) at ABC.com. All databases are hosted on
Windows Server 2012 servers running SQL Server 2012.
The Sales department uses a database named SalesDB. SalesDB contains a large table
named Orders that lists every order received by the company in the last 10 years.
You want to partition improve the performance of SalesDB by partitioning the Orders table
into 10 partitions based on year.
Which of the following describes how you should partition the table?

company uses a Microsoft SQL Server 2012 infrastructure that includes more than 50
servers.
A new company security policy states a list of minimum security requirements for all SQL

servers.
You need to implement a solution to ensure that all servers adhere to the company security
policy.
What should you do?

Windows Server 2012 servers running SQL Server 2012.
The company has a database named Products. Tables in the Products database contain
data including part numbers, product name, color, type and size.
Users in the Marketing department have created brochures for each product. The
brochures have been created in the XML Paper Specification (XPS) format.
You have been asked to add a table to the Products database to store the product
brochures. The brochures need to be stored in a folder structure. Company users will also
need to access the brochures from Windows applications using UNC paths.
How can you meet these requirements?
