2707 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

44 questions in Delivery & Release Engineering.

  1. Environment Strategy intermediate

    Six teams share one staging environment. Booking it is a bottleneck and it is permanently broken by whoever deployed last. Design a way out.

  2. Environment Strategy intermediate

    You have one quarter to delete the shared staging environment that eight teams deploy into. Sequence the work so each step is reversible, say where the point of no return actually is, and name what cannot move.

  3. Flow Metrics intermediate

    A platform team reports deployment frequency of 12 per day, lead time for changes of 40 minutes, change failure rate of 2% and recovery time of 18 minutes - elite on every band. Incidents have risen 40% over two quarters. Review the measurement.

  5. Flow Metrics intermediate

    An engineering director tells you that team A has a change failure rate of 2% and team B's is 18%, and asks you to find out what team A is doing right so the practice can be spread. Walk me through how you would answer.

  7. GitOps intermediate

    A platform adopts a declarative, git-driven deployment model. What does it improve, and what does it not solve?

  8. GitOps intermediate

    A platform manages infrastructure declaratively and production has diverged from the declarations. Is that a failure of discipline?

  9. GitOps intermediate

    You are adopting GitOps. Someone asks how secrets work, since the repository is the source of truth. What are the options and which do you choose?

  10. IaC Modules & Drift intermediate

    An organisation's infrastructure code has become a sprawl of copied configurations. What module strategy works, and how is drift handled?

  11. IaC Modules & Drift intermediate

    Your infrastructure drift detection fires 200 alerts a day. The team has muted it. How do you make it useful again?

  12. Multi-Region Rollout intermediate Multiple choice

    Your deployment updates all four regions in parallel to keep versions consistent. Argue for or against.
