DevOps Foundation Certification Exam 2026: Professional Practice
Test — DevOps Principles, CI/CD, Automation, Monitoring,
Collaboration, Value Streams & Continuous Improvement — 190
Multiple-Choice Questions with Answers & Detailed Rationales
Section 1: DevOps Fundamentals and Culture (Questions 1–30)
Question 1
What is the primary goal of DevOps as a professional discipline?
A. To replace all manual operations with artificial intelligence
B. To shorten the systems development life cycle while delivering features, fixes, and
updates frequently
C. To eliminate the need for quality assurance teams
D. To ensure developers write code without any operational input
Correct Answer: B
Explanation: DevOps aims to shorten the development life cycle and deliver value
continuously through collaboration and automation, not to eliminate roles or replace
humans entirely.
Question 2
Which concept describes the shared responsibility model where development and
operations teams collaborate throughout the entire product lifecycle?
A. Waterfall governance
B. DevOps culture
C. Outsourced operations
,D. Isolated deployment
Correct Answer: B
Explanation: DevOps culture emphasizes shared ownership, collaboration, and continuous
feedback between development and operations teams across the whole lifecycle.
Question 3
A company notices that developers "throw code over the wall" to operations, causing
frequent deployment failures. Which DevOps principle most directly addresses this
problem?
A. Increasing documentation handoffs
B. Breaking down silos between development and operations
C. Adding more approval gates
D. Lengthening release cycles
Correct Answer: B
Explanation: DevOps principles advocate eliminating organizational silos so teams share
goals, tools, and accountability, reducing handoff-related failures.
Question 4
What does "shift left" mean in a DevOps context?
A. Moving testing and security earlier in the development lifecycle
B. Moving production servers to the left side of the data center
,C. Deferring all quality checks until release
D. Shifting responsibility entirely to operations
Correct Answer: A
Explanation: Shift left means integrating testing, security, and quality practices earlier in the
lifecycle to detect issues sooner and reduce remediation cost.
Question 5
Which of the following best illustrates the "fail fast" principle in DevOps?
A. Avoiding deployments to prevent errors
B. Detecting failures quickly through automated testing and feedback loops
C. Ignoring minor defects until a major release
D. Punishing teams for any failure
Correct Answer: B
Explanation: Fail fast encourages rapid detection of problems via automated tests and
feedback so teams can learn and correct issues quickly.
Question 6
Which metric measures the time from code commit to running in production?
A. Mean time to recovery (MTTR)
B. Lead time for changes
, C. Change failure rate
D. Deployment frequency
Correct Answer: B
Explanation: Lead time for changes measures how long it takes from code commit until it is
running successfully in production, a key DORA metric.
Question 7
A team deploys multiple times per day with low failure rates. Which DORA metric does this
behavior directly improve?
A. Change failure rate only
B. Deployment frequency
C. Mean time to failure
D. Incident severity
Correct Answer: B
Explanation: Deployment frequency measures how often an organization successfully
releases to production, and frequent low-risk deployments demonstrate elite performance.
Question 8
Which of the following describes mean time to recovery (MTTR)?
A. The average time taken to detect a defect during code review
B. The average time to restore service after an incident
