What is a DFD?

• A diagram which shows the connectivity between different items of data.

• A diagram that shows the screens that the user will interact with and how they will navigate through the solution.

• A diagram that represents a sequence of steps needed to solve a problem.

• A diagram providing a snapshot of all or part of a system, as if all possible tasks are being undertaken at that moment.

What diagramming technique is used to illustrate the navigation between screens?

• A Storyboard

• A DFD (Data Flow Diagram)

• An ERD (Entity Relationship Diagram)

• A Flowchart

What is Regression testing?

• Testing by non-programmers to test that expected functionality is present and that it works as it should.

• Testing how the components perform when they interact with each other.

• Testing using previous test, carried out when changes have been made to ensure nothing has been affected.

• Testing the smallest arts of the program using white box principles.

Which post-coding technique would you employ with non-programmers to test the functionality of the solution?

• Integration testing

• Regression testing

• White box testing

• Black box testing

Which deployment option would you choose if you wanted to switch off the existing system on a Friday and start the new one on a Monday?

• Parallel

• Direct

• Phased

• Pilot

What type of maintenance is carried out immediately after deployment to fix bugs?

• Perfective

• Intensive

• Corrective

• Adaptive

What is the main drawback of the Waterfall Model?

• It is unstructured.

• If mistakes have been made you can not go back to an earlier phase.

• You need high levels of collaboration.

• It is often used by inexperienced development teams.
