QUESTION 1
You use Visual Studio .NET to create an employee database application for
Certkiller Ltd. Your application contains the following code segment. (Line numbers
are included for reference only.
01 foreach(Employee oEmployee in oCompany.Employees) {
02 bsuccess=RecordsUpdate (o Employee); 03 }
When you debug your application, you discover that RecordsUpdate sometimes
returns a value of False. As quickly as possible, you need to debug your application
and find all instances where RecordsUpdate returns this value.
What should you do?
A. Set a breakpoint on line 1. Step through the code after the breakpoint is reached.
B. Set a breakpoint on line 2. Step through the code after the breakpoint is reached.
C. Set a breakpoint on line 1. Set its Condition property to !bSuccess and select the has
changed option.
D. Set a breakpoint on line 2. Set its Condition property to bSuccess and select the is true
option.
E. Set a breakpoint on line 2. Set its Condition property to !bSuccess and select the is true
option.
F. Add a watch expression for bSuccess. Select the option Break when value is true.
Answer: E
Explanation: We must put the breakpoint on the line that contains that sets the
variable we are interested in. Furthermore, we must set a condition. We should set
the condition to !bSuccess, which stands for not BSuccess, since we want to find all
instances where the Bsuccess is false.
Reference: 70-306/70-316 Training kit, Setting Breakpoints, Pages 211-212
Incorrect Answers
A, C: We must set the breakpoint at line 2.
B: We are only interested in when bSuccess has a value of False.
D: This breakpoint would stop the execution whenever BSuccess is set to true.

F: The Watch window is just used to track a variable or expression. You cannot break
out of this tracing.
QUESTION 2
You develop an application, Certkiller Remote, that enables mobile salespeople to
look up contact information in a database. The salespeople use portable computers
running Windows XP Professional.
Because of the large size of the database, you want to create a distribution package
to distribute your application and the database on a CD-ROM. However, you
discover that the total size of the distribution package exceeds the capacity of a
650-MB CD-ROM. You want to reduce the size of the distribution package so it will
fit on a single CD-ROM.
Which two actions should you take? (Each correct answer presents part of the
solution. Choose two)
A. Exclude the .NET Framework dependency from your distribution package.
B. Use a third-party compression utility to compress the .NET Framework dependency
files.
C. Set the package files option of your setup project to In cabinet file(s) and set the
maximum CAB file size to 650 MB.
D. Set the Compression property of your setup project to Optimized for size.
E. Set the Bootstrapper property of your setup project to None.
Answer: A, D
Explanation:
A: The Windows XP operating system includes the .NET Framework already. We can
safely exclude it from the distribution package. The size o
Note: The .NET Framework merge module is automatically added as a dependency for
any application built with the .NET Framework. You should exclude the merge module
only if you are sure that the application will only be installed where the .NET Framework
run-time files are already installed.
D: If you choose Optimized For Size, the setup project will be the smallest possible size,
but might require more time to install.

Modules
Incorrect Answers
B: Third party compression utilities are not used to compress Visual Studio .NET
projects.
C: A maximum cab size of 650MB would enable spanning the application to several
CDs. However, we want the application to fit on a single CD.

E: The Bootstrapper property specifies whether a bootstrapper (bootstrapping
application) will be included in an installer. A bootstrapper includes the files needed to
install Microsoft Windows Installer 1.5 on the target computer if it is not already
installed. Windows installer 1.5 is already included in Windows XP but is required for
earlier operating systems.
Setting the Bootstrapper property to None would reduce the project size. However, not as
much as A) or D).
QUESTION 3
You use Visual Studio .NET to create a component Certkiller Shared that will be
shared by two client applications. Eventually, you plan to deploy new version of
Certkiller Shared. However, not all of the new versions will be compatible with both
client applications.
When you deploy Certkiller Shared and the client applications, you must ensure that
you can upgrade the Certkiller Shared for a single client application. You must also
minimize the need for configuration changes when you deploy new version of the
component.
What are two possible ways to achieve your goal? (Each correct answer presents a
complete solution. Choose two)
A. Deploy each client application to its own folder.
Deploy Certkiller Shared to its own folder.
Register Certkiller Shared by using RegSvr32 with the /s option.
B. Deploy each client application to its own folder.
Deploy a separate copy of Certkiller Shared to each client application folder.
When you deploy a new version of Certkiller Shared, replace the older version only if the
new version remains compatible with the client application in the same folder.
C. Compile the client applications with reference to Certkiller Shared.
Deploy both client applications and Certkiller Shared to a single folder.
When you deploy a new version of Certkiller Shared, increment its version number.
D. Create a strong name of Certkiller Shared and specify a version number.
Compile each client application and bind it to Certkiller Shared.
Deploy Certkiller Shared to the global assembly cache on the client computer.
Deploy each client application to its own folder.
When you deploy a new version of Certkiller Shared, increment its version number.
Answer: B, D
Explanation:
B: We keep two separate copies of the shared component. And we only replace the
shared copy of the component if compatibility is still maintained.
D: You can install multiple versions of the same assembly to the Global Assembly
Cache, and applications can locate and use the appropriate version.

Incorrect Answers
A: RegSrv32 was used in Visual Basic 6.0 and Visual C++ 6.0 and earlier. It is no longer
used in Visual Studio .Net.
C: The shared component might be compatible with both client applications. We should
use the global assembly cache, not put Certkiller Shared and the client applications in the
same folder.
