Question 1

What is the goal of chaos engineering in a DevOps quality assurance strategy?

Accepted Answer

To proactively inject failures to identify weaknesses in system resilience before they cause outages

Answer

To randomly deploy broken code to catch bugs

Answer

To test the chaos of concurrent user sessions

Answer

To disable monitoring to see if systems self-heal

Question 2

Which type of testing evaluates how a system performs under expected and peak load conditions?

Accepted Answer

Load and performance testing

Answer

Security penetration testing

Answer

Regression testing

Answer

Acceptance testing

Question 3

What is a 'test double' in the context of unit testing?

Accepted Answer

A generic term for objects that stand in for real dependencies (mocks, stubs, fakes) during testing

Answer

Running the same test twice to verify consistency

Answer

Doubling the number of assertions per test case

Answer

A backup test suite used when the primary suite fails

Question 4

In DevOps, what does 'test automation debt' refer to?

Accepted Answer

Answer

Technical debt caused by automated tests breaking the build

Answer

The cost of running tests on cloud infrastructure

Question 5

Which approach best describes 'continuous testing' in a DevOps pipeline?

Accepted Answer

Executing automated tests at every stage of the pipeline to provide immediate feedback

Answer

Running a full regression suite once per sprint

Answer

Hiring a dedicated QA team to test continuously during business hours

Answer

Deferring all tests to the production environment

Question 6

What is the primary risk of having a high percentage of end-to-end tests and few unit tests (an inverted testing pyramid)?

Accepted Answer

Slow, brittle, and expensive test suites that delay pipeline feedback

Answer

Too much code coverage

Answer

Over-testing of individual functions

Answer

Lack of UI validation

Question 7

Which DevOps practice involves running two identical production environments and switching traffic between them to enable zero-downtime deployments with automated testing validation?
