Just updated: 6 certifications re-aligned to current exam blueprints

Updated September 22, 2026

We re-checked every certification's domain structure against each vendor's live exam guide. Six had drifted — missing domains, wrong exam codes, or stale weightings — and are now corrected, with new practice questions, flashcards, and a full study guide for every newly added domain.
