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 2014 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 USP_1 generates millions of rows of data for multiple reports. USP_1 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 USP_2 is used to generate a product list. USP_2 takes several minutes to run due
to locks on the tables the procedure accesses.
A stored procedure named USP_3 is used to update prices. USP_3 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 USP_4 calls stored procedures in the Sales, Customers, and Inventory databases.
The nested stored procedures read tables from the Sales, Customers, and Inventory databases. USP_4 usesan EXECUTE AS clause.
A stored procedure named USP_5 changes data in multiple databases. Security checks are performed each
time USP_5 accesses a database.
You suspect that the security checks are slowing down the performance of USP_5.
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:
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.

Background
Corporate Information
Fabrikam, Inc. is a retailer that sells electronics products on the Internet. The company has a headquarters site
and one satellite sales office.
You have been hired as the database administrator, and the company wants you to change the architecture of
the Fabrikam ecommerce site to optimize performance and reduce downtime while keeping capital
expenditures to a minimum. To help with the solution, Fabrikam has decided to use cloud resources as well as
on-premise servers.
Physical Locations
All of the corporate executives, product managers, and support staff are stationed at the headquarters office.
Half of the sales force works at this location.
There is also a satellite sales office. The other half of the sales force works at the satellite office in order to
have sales people closer to clients in that area. Only sales people work at the satellite location.
Problem Statement
To be successful, Fabrikam needs a website that is fast and has a high degree of system uptime. The current
system operates on a single server and the company is not happy with the single point of failure this presents.
The current nightly backups have been failing due to insufficient space on the available drives and manual drive
cleanup often needing to happen to get past the errors. Additional space will not be made available for backups
on the HQ or satellite servers. During your investigation, you discover that the sales force reports are causing
significant contention.
Configuration
Windows Logins
The network administrators have set up Windows groups to make it easier to manage security. Users may
belong to more than one group depending on their role.
The groups have been set up as shown in the following table:

Server Configuration
The IT department has configured two physical servers with Microsoft Windows Server 2012 R2 and SQL
Server 2014 Enterprise Edition and one Windows Azure Server. There are two tiers of storage available for use
by database files only a fast tier and a slower tier. Currently the data and log files are stored on the fast tier of
storage only. If a possible use case exists, management would like to utilize the slower tier storage for data
files.
The servers are configured as shown in the following table:

Database
Currently all information is stored in a single database called ProdDB, created with the following script:

The Product table is in the Production schema owned by the ProductionStaff Windows group. It is the main
table in the system so access to information in the Product table should be as fast as possible.
The columns in the Product table are defined as shown in the following table:

The SalesOrderDetail table holds the details about each sale. It is in the Sales schema owned by the SalesStaff
Windows group.
This table is constantly being updated, inserted into, and read.
The columns in the SalesOrderDetail table are defined as shown in the following table:

Database Issues
The current database does not perform well. Additionally, a recent disk problem caused the system to go down,
resulting in lost sales revenue. In reviewing the current system, you found that there are no automated
maintenance procedures. The database is severely fragmented, and everyone has read and write access.
RequirementsDatabase
The database should be configured to maximize uptime and to ensure that very little data is lost in the event of
a server failure. To help with performance, the database needs to be modified so that it can support in-memory
data, specifically for the Product table, which the CIO has indicated should be a memory-optimized table. The
auto-update statistics option is set off on this database.
Only product managers are allowed to add products or to make changes to the name, description, price, cost,
and supplier. The changes are made in an internal database and pushed to the Product table in ProdDB during
system maintenance time. Product managers and others working at the headquarters location also should be
able to generate reports that include supplier and cost information.
Customer data access
Customers access the company’s website to order products, so they must be able to read product information
such as name, description, and price from the Product table. When customers place orders, stored procedures
called by the website update product quantity-on-hand values. This means the product table is constantly
updated at random times.
Customer support data access
Customer support representatives need to be able to view and not update or change product information.
Management does not want the customer support representatives to be able to see the product cost or any
supplier information.
Sales force data access
Sales people at both the headquarters office and the satellite office must generate reports that read from the
Product and SalesOrderDetail tables. No updates or inserts are ever made by sales people. These reports are
run at random times and there can be no reporting downtime to refresh the data set except during the monthly
maintenance window. The reports that run from the satellite office are process intensive queries with large data
sets. Regardless of which office runs a sales force report, the SalesOrderDetail table should only return valid,
committed order data; any orders not yet committed should be ignored.
Historical Data
The system should keep historical information about customers who access the site so that sales people can
see how frequently customers log in and how long they stay on the site. The information should be stored in a
table called Customer Access. Supporting this requirement should have minimal impact on production website
performance.
Backups
The recovery strategy for Fabrikam needs to include the ability to do point in time restores and minimize the risk
of data loss by performing transaction log backups every 15 minutes.
Database Maintenance
The company has defined a maintenance window every month when the server can be unavailable. Any
maintenance functions that require exclusive access should be accomplished during that window.
Project milestones completed
Revoked all existing read and write access to the database, leaving the schema ownership in place.
Configured an Azure storage container secured with the storage account name MyStorageAccount with the
primary access key StorageAccountKey on the cloud file server.
SQL Server 2014 has been configured on the satellite server and is ready for use.
On each database server, the fast storage has been assigned to drive letter F:, and the slow storage has
been assigned to drive letter D:

the Fabrikam ecommerce site to optimize performance and reduce downtime while keeping capital
expenditures to a minimum. To help with the solution, Fabrikam has decided to use cloud resources as well as
on-premise servers.
Physical Locations
All of the corporate executives, product managers, and support staff are stationed at the headquarters office.
Half of the sales force works at this location.
There is also a satellite sales office. The other half of the sales force works at the satellite office in order to
have sales people closer to clients in that area. Only sales people work at the satellite location.
Problem Statement
To be successful, Fabrikam needs a website that is fast and has a high degree of system uptime. The current
system operates on a single server and the company is not happy with the single point of failure this presents.
The current nightly backups have been failing due to insufficient space on the available drives and manual drive
cleanup often needing to happen to get past the errors. Additional space will not be made available for backups
on the HQ or satellite servers. During your investigation, you discover that the sales force reports are causing
significant contention.
Configuration
Windows Logins
The network administrators have set up Windows groups to make it easier to manage security. Users may
belong to more than one group depending on their role.
The groups have been set up as shown in the following table:

Server Configuration
The IT department has configured two physical servers with Microsoft Windows Server 2012 R2 and SQL
Server 2014 Enterprise Edition and one Windows Azure Server. There are two tiers of storage available for use
by database files only a fast tier and a slower tier. Currently the data and log files are stored on the fast tier of
storage only. If a possible use case exists, management would like to utilize the slower tier storage for data
files.
The servers are configured as shown in the following table:

Database
Currently all information is stored in a single database called ProdDB, created with the following script:

The Product table is in the Production schema owned by the ProductionStaff Windows group. It is the main
table in the system so access to information in the Product table should be as fast as possible.
The columns in the Product table are defined as shown in the following table:

The SalesOrderDetail table holds the details about each sale. It is in the Sales schema owned by the SalesStaff
Windows group.
This table is constantly being updated, inserted into, and read.
The columns in the SalesOrderDetail table are defined as shown in the following table:

Database Issues
The current database does not perform well. Additionally, a recent disk problem caused the system to go down,
resulting in lost sales revenue. In reviewing the current system, you found that there are no automated
maintenance procedures. The database is severely fragmented, and everyone has read and write access.
RequirementsDatabase
The database should be configured to maximize uptime and to ensure that very little data is lost in the event of
a server failure. To help with performance, the database needs to be modified so that it can support in-memory
data, specifically for the Product table, which the CIO has indicated should be a memory-optimized table. The
auto-update statistics option is set off on this database.
Only product managers are allowed to add products or to make changes to the name, description, price, cost,
and supplier. The changes are made in an internal database and pushed to the Product table in ProdDB during
system maintenance time. Product managers and others working at the headquarters location also should be
able to generate reports that include supplier and cost information.
Customer data access
Customers access the company’s website to order products, so they must be able to read product information
such as name, description, and price from the Product table. When customers place orders, stored procedures
called by the website update product quantity-on-hand values. This means the product table is constantly
updated at random times.
Customer support data access
Customer support representatives need to be able to view and not update or change product information.
Management does not want the customer support representatives to be able to see the product cost or any
supplier information.
Sales force data access
Sales people at both the headquarters office and the satellite office must generate reports that read from the
Product and SalesOrderDetail tables. No updates or inserts are ever made by sales people. These reports are
run at random times and there can be no reporting downtime to refresh the data set except during the monthly
maintenance window. The reports that run from the satellite office are process intensive queries with large data
sets. Regardless of which office runs a sales force report, the SalesOrderDetail table should only return valid,
committed order data; any orders not yet committed should be ignored.
Historical Data
The system should keep historical information about customers who access the site so that sales people can
see how frequently customers log in and how long they stay on the site. The information should be stored in a
table called Customer Access. Supporting this requirement should have minimal impact on production website
performance.
Backups
The recovery strategy for Fabrikam needs to include the ability to do point in time restores and minimize the risk
of data loss by performing transaction log backups every 15 minutes.
Database Maintenance
The company has defined a maintenance window every month when the server can be unavailable. Any
maintenance functions that require exclusive access should be accomplished during that window.
Project milestones completed
Revoked all existing read and write access to the database, leaving the schema ownership in place.
Configured an Azure storage container secured with the storage account name MyStorageAccount with the
primary access key StorageAccountKey on the cloud file server.
SQL Server 2014 has been configured on the satellite server and is ready for use.
On each database server, the fast storage has been assigned to drive letter F:, and the slow storage has
been assigned to drive letter D:
