Selected Answer: A
Fault attacks are a way to implement error guessing. This test technique requires the tester to create or acquire a list of possible errors, defects and failures, and to design tests that will identify defects associated with the errors, expose the defects, or cause the failures. These lists can be built based on experience, defect and failure data, or from common knowledge about why software fails.
