Practice 1
Use dependencies.json to annotate a service dependency map and record availability for cloud-west and outbound-channel failures.
Compare with a sample answer
For cloud-west, primary=false, secondary=false, independent=true. For outbound-channel, all three are false. Different model names do not remove shared hosting. Capacity, access, record quality, staff readiness, channel operation and authorised use still require evidence. Success requires the common dependencies and both failure results, with no claim that graph availability proves recovery.
Ungraded practice. Review evidence, intermediate reasoning, scope and unresolved gaps against the worked guide. Keyword matching does not establish practical competence.
