Read the first 6 DevOps & Automation flashcards as text

  1. What is a 'pipeline as code' approach?

    Answer: Defining CI/CD pipeline configuration in version-controlled files

    Pipeline as code stores the CI/CD configuration in source control alongside the application, enabling versioning, review, and automated execution.

  2. In a microservices architecture, what tool category handles service discovery and load balancing?

    Answer: Service mesh

    A service mesh like Istio or Linkerd handles service-to-service communication, load balancing, and observability within a microservices environment.

  3. What does 'mean time to recovery' (MTTR) measure in DevOps?

    Answer: Average time to restore service after a failure

    MTTR measures how quickly a team can restore a system to normal operation after an incident, indicating operational resilience.

  4. Which security practice scans container images for known CVEs before deployment?

    Answer: Container image scanning

    Container image scanning tools like Trivy or Snyk analyze image layers against vulnerability databases to detect CVEs before images reach production.

  5. What is the purpose of a feature flag in continuous delivery?

    Answer: Enabling or disabling features at runtime without redeployment

    Feature flags allow teams to deploy code to production while keeping new functionality hidden or restricted until it is ready to be revealed.

  6. Which strategy deploys a new version to a small subset of users before a full rollout?

    Answer: Canary release

    A canary release routes a small percentage of traffic to the new version, allowing teams to validate it in production before exposing all users.
