You enter sample data to exam the application. The following exception is caught by the data
layer before the application continues to run. Cannot set column ?Column1? to ?Text too long for
maximum length?. The value violates the MaxLength limit of this column.
You need to improve the security of the application. Which two actions should you perform?
(Each correct answer presents part of the solution. Choose two)
A. Increase the maximum length of data characters allowed in the column.
B. Validate all incoming data character lengths at the business layer.
C. Modify the data layer to process data above the maximum length.
D. Modify the user interface to prevent users from entering data above the maximum character
length.

B. Validate all incoming data character lengths at the business layer.

length.

7. Suppose Each client computer in Company runs
either Microsoft Windows XP Professional or Windows 98. You are developing an application that
will be used by all users in Company.
Users log on to their client computers by using a domain user account that is a member of the
local Power Users group and the user?s computer. You log on to your Windows XP Professional
computer by using a domain user account that is a member of the local Administrators group and
Power Users group on your computer.
When examing your application, you need to ensure that your exams accurately reflect the
production environment in which the application will run.
How should you exam the application?
A. Ask a domain administrator to temporarily remove your domain user account from the local
Administrators group on your computer while you are examing the application.
B. Exam the application on your computer.
When examing, log on to the computer by using a domain user account that is a member of
only the local Power Users group on your computer.
C. Deploy the application to a Windows XP Professional computer and a Windows 98 computer.
Log on to each computer by using a domain user account that is a member of only the local
Power Users group.
D. Compile the assemblies of the application from the command line by running the runas
command and specifying a domain user account that is a member of only the local Power
Users group on your computer.

C. Deploy the application to a Windows XP Professional computer and a Windows 98 computer.
Log on to each computer by using a domain user account that is a member of only the local
Power Users group.

8. You create an ASP.NET Web application
that all authenticated network users will access. The authentication mode in the Web.config file is
currently set to None. Due to recent security threats, the network administrator requires that all
connections to the application?s Web server use the network credentials of the authenticated
user.

be used by members of three domain user groups in your company. The user groups are named
CompanySales, CompanyMarketing, and AccountManagement. Each of the three user groups
will have different permission within the application.
You log on to your development computer by using a domain user account that is a member of
only the Domain Users and the Developers domain user groups. On your development computer,
