Question 2

In a CI/CD pipeline, what is the purpose of a 'quality gate'?

Accepted Answer

To block a build from progressing if it fails defined quality criteria

Answer

Load testing evaluates system performance and stability under high concurrent user traffic conditions.

Question 4

What is 'chaos engineering' in the context of cloud quality assurance?

Accepted Answer

Intentionally injecting failures to test system resilience
