D. The application must be completed within a five-month development period before it is tested
Answer: C
Explanation:
C: Business Manager says that the vendor only meets its deadlines for delivering updates
only 50 percent of the time. This will have the greatest impact.

D: Since there is enough funding it should not be a problem.
Question 4.
You are establishing a policy to measure the effectiveness of your deployment process.
You decide to track one or more phases of development to identify defects. Which phase or phases should you track?(Choose all that apply)
A. Design and analysis
B. Development
C. Stabilization
D. Requirements
Answer: C
Explanation:
C: It is during the stabilizing phase that the Testing team completes the tasks and creates the deliverables that move the feature-complete build to a state in which the defined quality level is reached and the solution is ready for full production deployment.
The two main tasks in the stabilizing phase are:
• Testing the solution: The team implements the test plans that were created during the planning phase, which were enhanced and tested during the development phase.
• Conducting the pilot: The team moves a solution pilot from development to a staging area to test the solution with actual users and real scenarios. The pilot is conducted before the deploying phase is begun.
A pilot is a test of the solution in the production environment, and a trial of the solution by installers, systems support staff, and end users. The primary purposes of a pilot are to demonstrate that the design works in the production environment as expected and that it meets the organization’s business requirements. A secondary purpose is to give the deployment team a chance to practice and refine the deployment process.

Question 7.
You need to select a strategy that will provide detailed usage information for the new reservation application. Information must be provided with a minimum development effort. What should you do?
A. Use Microsoft .NET performance counters in the application
B. Create a Microsoft Management Console(MMC) snap-in for the application

A. TraceSwitch objects
B. Diagnostic tools
C. PerformanceCounter objects
D. Windows Management Instrumentation Job Object provider
Answer: C
Explanation:
Using the Performance Counter object within the solution would allow developers to write performance specific information that can be monitored by Performance Monitor while the application is running.
Question 9.

A. Data access object
B. Customer object

Question 10.
You are creating constraints for tables named Flight and Airport. You must ensure data integrity. Which action or actions should you take?(Choose all that apply)
A. Create a primary key constraint on the AirportCode column and the CityOfOrigin column in the
Airport table
B. Create a primary key constraint on the FlightNumber column in the Flight table
C. Create a cascading delete constraint on the AirportCode column in the Airport Table
D. Create a foreign key constraint on the ArriveAirportCode column in the Flight table to reference
the AirportCode column in the Airport table.
E. Create a primary key constraint on the FlightNumber column, the FilghtDate column and the
DepartAirportCode column in the Flight table
F. Create a foreign key constraint on the DepartAirportCode column in the Flight table to
reference the AirportCode column in the Airport table.
G. Create a primary key constraint on the AirportCode column in the Airport table.
H. Create a foreign key constraint on the AirportCode column in the Airport table to reference the
DepartAirportCode column in the Flight table
Answer: D, E, F, G
Explanation:
The answers will meet the design shown below:
• Primary Keys
o Airport Table: AirportCode is unique enough.
o Flight Table: Composite primary key for FlightNumber, FlightDate and
DepartAirportCode. (Flight Number itself may not be unique enough since they could be reused)
• Foreign Keys
o Airport Table: DepartAirportCode will reference AirportCode
o Airport Table: ArriveAirportCode will reference AirportCode.
• CityOfOrigin is not necessary to uniquely identify records within the Airport Table.
• FlightDate has to be part of the composite key within the Flight Table.
Having a cascade delete is a nice-to-have option on the database. It isn’t essential.
If you wish to delete an airport, you have 2 options:
o Delete all the related Flight records (programmatically) then delete the Airport record.
o Delete the Airport code and let the database delete all related flight children records.
