Requester: Birch technical lead. Inputs: fictional example rates and measured workload quantities supplied by the exercise. Question: calculate comparable inputs, preserve the required recovery controls, and choose a recommendation that states the tradeoffs and the remaining evidence.
Birch is comparing a simple synchronous service with a buffered design under a fixed reliability requirement. You will work through one account, carrying every accepted change into the next step. The initial resources are a fictional company's starting configuration, not a blank cloud account. Your deliverable is the final account state and the checked decision at the end.
Inspect the named resources before changing them. Earlier work remains part of the requirements, so a later step must preserve it. Some steps use a prepared JSON or YAML file; read its contents and then verify the resulting configuration. Other steps ask for a recommendation supported by the evidence you've established. The final check includes previous requirements as well as the new one, which prevents a quick repair from undoing an earlier protection.
