   A project is in the maintenance phase, and a small change is made to a critical module. The team has limited time and must decide whether to perform static testing, dynamic testing, or both. Which approach is most appropriate?

   • APerform only dynamic testing, as it is more important for verifying the change works.
   • BPerform both static testing (e.g., code review of the change) and dynamic testing (e.g., regression tests) to ensure the change is correct and does not break existing functionality.
   • CSkip both static and dynamic testing, as the change is small and unlikely to cause issues.
   • DPerform only static testing, as it is faster and can find defects without executing the code.

   A team is developing a safety-critical system where a failure could have severe consequences. They want to maximize defect detection. Which combination of testing approaches is most appropriate?

   • AUse only static testing, as it is cheaper and finds defects early.
   • BUse only dynamic testing, as it is the most reliable way to find defects.
   • CUse both static testing (reviews and static analysis) and dynamic testing (functional and structural) throughout the lifecycle.
   • DUse dynamic testing first, then static testing only if time permits.

   A team is starting a new project and wants to improve the quality of their code before it is even compiled. Which objective is best achieved by static testing?

   • AMeasuring the performance of the software under a specific workload.
   • BDetecting runtime failures such as memory leaks and crashes.
   • CFinding defects early in the development process, such as syntax errors and logic flaws in the code.
   • DVerifying that the software behaves correctly under various input conditions.

   A tester runs a program with a set of test inputs and verifies that the outputs match the expected results. This activity is an example of:

   • AStatic analysis
   • BCode review
   • CStatic testing
   • DDynamic testing

   What is the key difference between static testing and dynamic testing?

   • ADynamic testing is only used for functional testing, while static testing is only used for non-functional testing
   • BStatic testing is performed by developers, while dynamic testing is performed by testers
   • CStatic testing does not execute the code, while dynamic testing requires code execution
   • DStatic testing finds more defects than dynamic testing
