QUESTION 1
You are contracted to create an ASP.Net web site for CKPowerLight Inc. CKPowerLight Inc is a large
regional provider of electrical services for residential and business customers. The database stores and
manipulates data in a Microsoft SQL Server database CKPowerLightDB. One of the pages in the
application will be used for performing month-end operations to calculate the electricity bill of
customers.
When a user clicks a button on the page, you want your code to run several stored procedures to
calculate the month-end balances. These procedures must all succeed before the calculated balances can

be stored in the database. If any of the procedures fail, then you do not want to store any of the monthend
calculated balances. While the procedures are running, you do not want any users to be able to edit,
add, or delete the tables affected by the procedures.
What should you do?
A. Set the IsolationLevel property of a SqlTransaction object to IsolationLevel.Serializable.
Assign the SqlTransaction object to the Transaction property of the SqlCommand object.
Use a SqlCommand object to run the stored procedures.
B. Create a class derived from System.EnterpriseServices.ServicesComponent to run the stored procedures.
Annotate the class by using a TransactionAttribute type of attribute.
Set the Value property of the attribute to TransactionOption.RequiresNew.
C. Create a master stored procedure.
Use this master stored procedure to call the other stored procedures that perform the month-end
operations.
Add WITH REPEATABLEREAD to the master stored procedure.
D. Use structured exception handling to catch a SqlException if one of the stored procedures fails.
Use the Procedure property of the SqlException to identify which stored procedure generated the
exception, and call a stored procedure to reserve the previous calculations.
Answer: A
We should use a Transaction to ensure that either all stored procedures will succeed or if one stored procedure
fails, the whole transaction will be backtracked. Furthermore, in order to protect the data in tables during the
transaction, we should use the highest transaction isolation level of Serializable. We use a SQLCommand object
to run the stored procedure. We set the Transaction property of the SqlCommand to the SqlTransaction object
we created.
QUESTION 2
You are creating an ASP.NET page for selling intercity airline flights tickets. Users select a region, and
then they select from a list of cities in that region. The site displays the names and locations of airports in
the city selected by the user.
Your company, Certkiller FlyAway Inc, maintains a list of airports in a database table that includes the
city, airport name, and airport code of each airport. You want to minimize the time required to retrieve
and display the list of airport names after a user selects the region and city.
What should you do?
A. Modify the connection string to add the packet size property and set its values to 8192.
B. Add the following directive to the page:
OutputCache VaryByControl=”region;city”
C. Modify the connection string to keep your database’s connection pool as small as possible.
D. Add the following directive to the page:
OutputCache VaryByParam=”city”
Answer: D
You can vary user control output to the cache by specifying the user control name and the parameter. We use
the VaryByParam attribute of the @ OutputCache

QUESTION 3
You are creating an ASP.NET application using C# for ShalomInc. ShalomInc is an international hotel
resort which has just acquired LebanonResorts Inc. Your application must consolidate data with a few
requirements. The new application will be used to identify potential customers.
Your application will call an XML Web service run by LebanonResorts Inc. The XML Web service will
return an ADO.NET DataSet object containing a list of companies that purchase wine. You want to
merge this DataSet object into a DataSet object containing a list of companies that are potential
customers.
You specify LebanonResorts as the name of the DataSet object from LebanonResorts Inc, and you
specify customerProspects as the name of the DataSet object containing potential customers. After the
data merge, ShalomInc will include the company names in LebanonResorts.
The two DataSet objects contain tables that have the same names and primary keys. The tables in the two
DataSet objects contain columns that have the same names and data types. A table in LebanonResorts
also contains additional columns that you do not want to add to ShalomInc. If ShalomInc included any
tables containing rows with pending changes, you want to preserve the current values in those rows when
the merge occurs.
Which line of code should you use to merge the LebanonResorts DataSet object into ShalomInc DataSet
object?
A. ShalomInc.Merge (LebanonResorts, true, MissingSchemaAction.Ignore);
B. ShalomInc.Merge (LebanonResorts, true, MissingSchemaAction.AddWithKey);
C. LebanonResorts.Merge (ShalomInc, true, MissingSchemaAction.Ignore);
D. LebanonResorts.Merge (ShalomInc, true, MissingSchemaAction.Add);
Answer: A
The DataSet.Merge (DataTable, Boolean, MissingSchemaAction) method merges this DataTable with a
specified DataTable preserving changes according to the specified argument, and handling an incompatible
schema according to the specified argument.
As we want to merge the DataSets into the LebanonResorts DataSet we should apply the merge method on
LebanonResorts.
The Ignore MissingSchemaAction ignores the extra columns. This meets the requirement not to add the extra
columns from the table in LebanonResorts that contains additional columns.
