  4. Compute Models intermediate

    A fleet of 200 instances averages 15% CPU and 85% memory. Finance wants a 40% cost reduction. What do you do?

  5. Compute Models intermediate

    A workload runs continuously at moderate load. Finance asks why the serverless bill is four times the previous instance cost. Explain the crossover and how you would calculate it.

  6. 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?

  7. 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?

  9. 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?
