What is the primary purpose of acceptance testing?

To integrate system components
To test the components independently
To test the system with data from the customer (correct)
To find errors resulting from unanticipated interactions

What is the main reason for incorporating more software into large complex systems?

Increasing system complexity
Testing phase requirements
Reducing initial development costs
Flexibility of software systems (correct)

In the V-model of development, what happens during system testing?

System components are integrated (correct)
Components are tested independently
Acceptance testing is performed
Unanticipated interactions are sought
