Capabilities you will practice

Four connected foundation courses with worked traces, required applied practice, and separate exam cases.

Tracking contracts

Check occurrence time, actor identity, numeric units, and authoritative business success.

Identity and account attribution

Trace anonymous-to-known transitions, logout boundaries, tenant IDs, and event group keys.

SQL metrics with evidence

Work through query fragments, join multiplicity, zero-usage accounts, and independent result fixtures.

Bounded ingestion recovery

Inspect capture responses, quota evidence, source retention, and the checks needed before replay or closure.

How it works

1

Find the next foundation

A diagnostic estimates your starting point across the connected concepts.

2

Study one step at a time

Read or listen to a rule, follow a worked trace, then apply it to concrete evidence.

3

Check transfer

Required applied practice and separate exam cases test whether you can use the rule with unfamiliar evidence.
