  1. Prospective validation

  2. Concurrent validation

  3. Retrospective validation

  4. Stress testing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Retrospective validation involves conducting validation activities after the process has been in operation for a period of time, typically based on historical data and process performance records.

Multiple choice

What is the Turing Test?

  1. A test to determine if a machine can exhibit intelligent behavior indistinguishable from that of a human

  2. A test to determine if a machine can perform tasks that typically require human intelligence

  3. A test to determine if a machine can think and reason like a human

  4. A test to determine if a machine can interact with humans in a natural way
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Turing Test is a test to determine if a machine can exhibit intelligent behavior indistinguishable from that of a human. It involves a human evaluator interacting with a machine through a text-based interface, and trying to determine if the machine is a human or a computer.

Multiple choice

What is the most effective way to prevent errors from occurring?

  1. Use a high-level programming language

  2. Write clear and concise code

  3. Test the program thoroughly

  4. Use error-handling techniques
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Writing clear and concise code is the most effective way to prevent errors from occurring. This makes it easier to identify and fix errors when they do occur.

Multiple choice

Which of the following is a quantitative measure of maintainability?

  1. Mean Time to Repair (MTTR).

  2. Mean Time Between Failures (MTBF).

  3. Availability.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

MTTR, MTBF, and Availability are all quantitative metrics used to assess the maintainability of a system.

Multiple choice

What are some of the common tests included in a dynamic FCE?

  1. Gait analysis

  2. Functional reach test

  3. Sit-to-stand test

  4. Step-up test

  5. All of the above
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Common tests included in a dynamic FCE include gait analysis, functional reach test, sit-to-stand test, and step-up test.

Multiple choice

What are the two main types of software testing?

  1. Functional testing and non-functional testing

  2. Unit testing and integration testing

  3. White-box testing and black-box testing

  4. Static testing and dynamic testing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The two main types of software testing are functional testing and non-functional testing. Functional testing verifies that the software meets its functional requirements, while non-functional testing verifies that the software meets its non-functional requirements, such as performance, security, and usability.

Multiple choice

What is the difference between unit testing and integration testing?

  1. Unit testing tests individual units of code, while integration testing tests how different units of code work together.

  2. Unit testing is performed by developers, while integration testing is performed by testers.

  3. Unit testing is typically automated, while integration testing is typically manual.

  4. Unit testing is more important than integration testing.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Unit testing tests individual units of code, such as functions or methods, to ensure that they work as expected. Integration testing tests how different units of code work together to ensure that the overall software system works as expected.

Multiple choice

What is white-box testing?

  1. A type of testing that is based on the internal structure of the software

  2. A type of testing that is based on the external behavior of the software

  3. A type of testing that is performed by developers

  4. A type of testing that is performed by testers
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

White-box testing is a type of testing that is based on the internal structure of the software. It involves examining the code to identify potential defects or vulnerabilities.

Multiple choice

What is black-box testing?

  1. A type of testing that is based on the internal structure of the software

  2. A type of testing that is based on the external behavior of the software

  3. A type of testing that is performed by developers

  4. A type of testing that is performed by testers
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Black-box testing is a type of testing that is based on the external behavior of the software. It involves testing the software without examining its internal structure.

Multiple choice

What is static testing?

  1. A type of testing that is performed before the software is executed

  2. A type of testing that is performed after the software is executed

  3. A type of testing that is performed by developers

  4. A type of testing that is performed by testers
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Static testing is a type of testing that is performed before the software is executed. It involves examining the source code or other artifacts to identify potential defects or vulnerabilities.

Multiple choice

What is dynamic testing?

  1. A type of testing that is performed before the software is executed

  2. A type of testing that is performed after the software is executed

  3. A type of testing that is performed by developers

  4. A type of testing that is performed by testers
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Dynamic testing is a type of testing that is performed after the software is executed. It involves running the software and observing its behavior to identify potential defects or vulnerabilities.

Multiple choice

What is a test case?

  1. A set of inputs, expected outputs, and preconditions for a test

  4. A tool for performing a test
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A test case is a set of inputs, expected outputs, and preconditions for a test. It defines the conditions under which a test will be performed and the expected results of the test.
