Read the first 7 DevOps & Continuous Delivery flashcards as text
  1. In Disciplined Agile DevOps, what is the purpose of 'infrastructure as code' (IaC)?

    Answer: To manage and provision infrastructure through machine-readable configuration files rather than manual processes

    IaC treats infrastructure configuration as versioned, testable code, enabling consistent and repeatable environment provisioning.

  2. Which DevOps practice involves automatically rebuilding and testing all affected components when a shared library is updated?

    Answer: Continuous Integration with dependency scanning

    CI pipelines that trigger on upstream dependency changes ensure that library updates don't silently break consuming services.

  3. What is 'mean time to recovery' (MTTR) measuring in a DevOps context?

    Answer: Average time to restore service after a production incident

    MTTR measures organizational resilience by tracking how quickly teams can restore normal service after a failure.

  4. A DA coach is helping a team adopt DevOps. Which mindset shift is most fundamental?

    Answer: Breaking down the wall between development and operations to share responsibility for the full delivery lifecycle

    DevOps fundamentally requires dissolving the Dev/Ops silo so both sides share ownership of outcomes from code to production.

  5. In a blue-green deployment strategy, what role do the two environments play?

    Answer: One environment runs the current production version while the other hosts the new release, with traffic switched over instantly

    Blue-green deployments maintain two identical environments so traffic can be routed to the new version instantly with easy rollback.

  6. What is the primary benefit of 'trunk-based development' in a Continuous Delivery context?

    Answer: It reduces merge conflicts and integration pain by keeping changes small and integrated frequently to a single mainline

    Trunk-based development minimizes long-lived branches, reducing integration debt and making Continuous Integration practical.

  7. Which monitoring practice aligns best with a DevOps observability strategy?

    Answer: Collecting metrics, logs, and traces proactively to detect anomalies before users are impacted

    Observability through metrics, logs, and distributed traces enables proactive detection and rapid diagnosis of production issues.
