Full set: 40 questions
Answer options
A: More frequent code deployments
B: Faster lead times from commit to deploy
C: Faster mean times to recovery
D: Higher change failure rates Correct answer
Correct Answer:
D. Higher change failure rates
Explanation

According to DORA (DevOps Research and Assessment) State of DevOps Reports, software delivery performance is evaluated using four key metrics: Deployment Frequency, Lead Time for Changes, Mean Time to Restore Service (MTTR), and Change Failure Rate. High-performing organizations exhibit high deployment frequency, fast lead times, rapid recovery, and low change failure rates. In contrast, low-performing organizations suffer from significant delivery bottlenecks and poor stability, resulting in higher change failure rates. When low performers attempt deployments, a larger percentage of their changes cause production degradations or require immediate remediation, leading to increased operational instability and reduced business agility compared to high-performing IT organizations.

Why Incorrect

A. More frequent code deployments: Low performers deploy significantly less frequently (e.g., monthly to semi-annually) compared to high performers who deploy multiple times daily.
B. Faster lead times from commit to deploy: Low performers experience longer lead times for changes, often taking weeks or months from code commit to production deployment.
C. Faster mean times to recovery: Low performers take considerably longer to restore service during incidents, often requiring days or weeks rather than minutes or hours.
