Q: What is a canary deployment?
A: Release to a small subset of users/servers first. Monitor health metrics. If successful, gradually expand to all users. Rollback if issues detected.
Q: What are the four DORA metrics?
A: Deployment Frequency, Lead Time for Changes, Mean Time to Recovery (MTTR), and Change Failure Rate. They measure DevOps performance.
Q: What is an error budget?
A: The amount of unreliability allowed before SLO is breached. If error budget is consumed, the team prioritizes reliability over features.
Q: When should you use feature flags?
A: To decouple deployment from release, enable A/B testing, provide kill switches for features, and implement progressive rollouts without redeployment.
Q: What is a blameless postmortem?
A: An incident review focused on systemic causes rather than individual blame. Identifies improvements to processes, tooling, and monitoring.
Effective Azure Flashcard Study Method
For Azure certifications, we recommend the spaced repetition approach: review these flashcards daily for the first week, then every other day for two weeks, then weekly until your exam date. Focus extra time on cards related to Azure service comparisons — understanding when to choose between similar services (e.g., App Service vs. AKS vs. Container Instances) is a common exam pattern.
