22. Cyclomatic Complexity method comes under which testing method.
a) Yellow box
b) White box
c) Gray box
d) Black box
Answer: B
Cyclomatic Complexity tells us about the number of independent paths in a program which is covered in white box testing.
23. Which is a black-box testing technique appropriate to all levels of testing?
a) Acceptance testing
b) Regression testing
c) Equivalence partitioning
d) Quality assurance
Answer: C
Equivalence partitioning is a software testing technique that divides the input data of a software unit into partitions of equivalent data from which test cases can be derived.
24. Which of the following is the way of ensuring that the tests are actually testing code?
a) Control structure testing
b) Complex path testing
c) Code coverage
d) Quality assurance of software
Answer: C
Code coverage is the way of ensuring that the tests are actually testing code. Code coverage is a software testing metric that determines the number of lines of code that are successfully validated under a test procedure, which in turn, helps in analyzing how comprehensively a software is verified.

29. Which part of the Xray can interface with a simulator?
A. emulator
B. debugger
C. simulator
D. onboard debugger
Answer: B
The Xray consists of a consistent debugger that can interface the emulator, simulator, task-level debugger, or onboard debugger.
30. Which can provide the consistent interface to the Xray?
A. emulator
B. simulator
C. memory simulator
D. debugger system
Answer: D
The Xray consists of the debugger which interfaces with the emulator, simulator, and onboard debugger that provides a consistent interface to the Xray product. This can improve the overall productivity of the product since it does not require any relearning.
