Part 6 exam: diagnosis and repair

The diagnosis exam: evidence questions on headers, bounces, triage, repair, verification and delisting, scored at the end.

Last updated 19 July 2026

The case file graded depth: one domain, read all the way down. The exam grades breadth. Twelve questions from across the part, and most of them hand you a piece of evidence (a header line, a bounce excerpt, a dig answer) and ask what it proves or what you do first, because that is the shape the work arrives in.

12 questions covering every lesson in this part. No feedback until the end, so answer the way you would in front of a client: committed. You get a score, a verdict, and the list of lessons to reread for anything you missed.

That was the last checkpoint exam. The practitioner track is next, and it opens with the audit workflow.
