Sample DevOps Practice Questions
Try these questions from our free DevOps practice tests. The correct answer and an explanation follow each question.
What is Site Reliability Engineering (SRE)?
- A. A discipline that applies software engineering principles to operations to create scalable, reliable systems
- B. A cloud security framework
- C. A deployment automation tool
- D. A microservices architecture pattern
Answer: A. A discipline that applies software engineering principles to operations to create scalable, reliable systems
SRE, originated at Google, treats operations as a software engineering problem, using code and automation to manage production systems and maintain reliability.
Which IaC tool uses a declarative language called HCL (HashiCorp Configuration Language)?
- A. Terraform
- B. Ansible
- C. Chef
- D. Puppet
Answer: A. Terraform
Terraform uses HCL to describe the desired state of infrastructure; it then creates, updates, or destroys resources to match that declared state.
9. Which DevOps practice backs up The Second Way?
- A. Peer review of production changes
- B. Value stream mapping
- C. Theory of constraints
- D. The Deming Cycle
Answer: A. Peer review of production changes
The Second Way of DevOps, the 'Way of Feedback,' emphasizes creating and amplifying feedback loops to prevent problems from recurring and to learn from failures. Peer review of production changes directly supports this by providing a critical feedback mechanism before changes impact users. It allows for early detection of potential issues, knowledge sharing, and learning from others' perspectives, thereby shortening and improving feedback loops.
22. An lT organization wishes to test their new DevOps practices on an upcoming release. Which of the following does NOT constitute a good pilot?
- A. Small enough that the consequences of any risk of failure have no significant business impact.
- B. Make a pilot that has the highest chance of success.
- C. Large enough so that you earn the right to make future improvements
- D. Enough to demonstrate the return on investment in DevOps.
Answer: D. Enough to demonstrate the return on investment in DevOps.
A good pilot project for new DevOps practices should be manageable, have a high chance of success, and be large enough to demonstrate the benefits and earn the right for future improvements. While demonstrating ROI is a long-term goal of DevOps, a pilot project itself might not be 'enough' to fully quantify the comprehensive ROI across the entire organization. Its primary purpose is to prove the concept, learn, and build confidence, not necessarily to provide a complete financial justification.
