1. Infrastructure as Code intermediate

    A platform manages infrastructure with code, but engineers make emergency console changes during incidents that are never reflected back. What problems does this drift cause, and how should it be handled without blocking incident response?

  2. Infrastructure as Code intermediate

    During an incident an engineer makes a manual change in the cloud console. It resolves the issue. What should happen next and what should have prevented it?

  3. Infrastructure as Code intermediate

    Half your production changes are made through the console during incidents. The IaC repository no longer matches reality. What do you do?

  4. Infrastructure as Code intermediate

    Infrastructure is defined as code, but production has drifted from the definitions through manual incident fixes. How should drift be handled, and what is wrong with simply enforcing the code?

  5. Ingestion Patterns intermediate

    A platform team proposes one ingestion standard: every source publishes to Kafka and the warehouse loads only from Kafka. That includes 40 SaaS connectors that pull once a day. The argument is one path, one set of tools, and replayability everywhere. Review it — what would you remove, what would you keep and what would you leave alone?

  6. Ingestion Patterns intermediate

    An analytics team extracts daily using a `modified_at` watermark. Reconciliation shows the warehouse has 3% more customers than the source. Why?

  7. Inner Loop & Outer Loop intermediate

    Developers cannot run the system locally — one service needs twelve dependencies. The inner loop is now "push and wait eight minutes". How do you fix it?

  8. Inner Loop & Outer Loop intermediate

    Engineers report that the platform is fine but daily development is slow. Where should a platform team invest?

  9. Inner Loop & Outer Loop intermediate Multiple choice

    Sixty engineers each wait for a build roughly 15 times a day. The build takes 4 minutes. Roughly what does that cost a year, and what does the number rule in or out?

  11. InnerSource intermediate

    An organisation adopts an innersource model so teams can contribute to each other's services. It mostly does not happen. What conditions does innersource require?

  12. InnerSource intermediate

    An organisation has published an innersource contribution guide, opened every internal repository, and added a company goal for cross-team contributions. Six months in there have been eleven contributions across 200 repositories. Review the programme.
