Yes. When a feature or capability is announced as being retired on a future date, it remains part of the product and associated learning content and exams until that retirement date.
For Microsoft certifications and exams, the general pattern is:
- Exams and their measured skills are periodically reviewed and updated to stay relevant.
- When an exam or specific content is scheduled for retirement, it continues to be available and testable up to the published retirement date.
Therefore, if Q&A is scheduled to be retired in December 2026, it is expected to remain in scope for PL-300 until either:
- The exam is updated to remove it before that date, or
- The exam itself is retired or replaced.
Candidates should always refer to the current “Skills measured”/exam outline on the official exam page shortly before taking the exam, as that document is the authoritative list of what can be tested at any given time.
