How to Find Authoritative Certification Exam Information

A surprising amount of certification advice on the internet is about exams that no longer exist. As of August 2026, CompTIA A+ candidates are sitting exams 220-1201 and 220-1202 — yet search results still surface guides, videos and question discussions built for the retired 220-1101/1102 series. Study the wrong version and you can lose weeks preparing for objectives that were rewritten, dropped or replaced.

The fix is not "only trust official sources" — third-party material has real value — but knowing which facts must come from the certification body, how to find the genuine current document, and how to spot the tell-tale signs of stale or unofficial information. That is what this article covers. It is about vetting information, not studying it; once you know a source is trustworthy, the method for turning it into knowledge lives in our workflow for researching an unfamiliar exam topic.

Which facts only the certification body can settle

Not every question needs an official answer. Advice, opinions and study strategies can come from anywhere sensible. But a specific set of facts changes over time, varies by region, and carries real cost if you get it wrong — and for those, the certification body's own pages are the only acceptable authority:

• The current exam code and version. Exams refresh on multi-year cycles. CompTIA's Security+ page, for instance, notes exams typically retire about three years after launch — so a guide's exam code is the fastest freshness check available.
• Exam objectives / the official blueprint. The testable content, in the vendor's own words and weightings.
• Format and scoring. Question counts, time limits, question types and passing scores differ by exam and change between versions. AWS publishes these in its exam guides, down to details like 15 unscored questions and the absence of a guessing penalty; Microsoft, by contrast, does not publish a fixed question count for AZ-900 on the certification page at all. Where the vendor is silent, treat any third-party number as a guess.
• Price. Fees vary by country and currency and change over time — Microsoft explicitly prices "based on the country or region in which the exam is proctored". Always confirm on the official store or registration page rather than trusting a number in an article, including this one.
• Prerequisites and eligibility. Some certifications require none (AWS Cloud Practitioner, AZ-900); ISC2's CISSP requires five years of cumulative paid work experience. Getting this wrong from a forum post can invalidate an application.
• Policies: retakes, renewal, testing rules. Retake waits, renewal programmes and online-proctoring rules are set per programme — Microsoft's 24-hour first-retake wait, CompTIA's Continuing Education programme, Pearson VUE's OnVUE requirements — and only the programme's own pages state them reliably.

Finding the genuine official page

Start at the certification body, not a search engine result

Search engines rank lookalike and affiliate pages highly, and some deliberately mimic official layouts. The robust route is: go to the certification body's main domain (comptia.org, aws.amazon.com/certification, learn.microsoft.com, isc2.org, isaca.org), then navigate to the certification through the site's own menus. Bookmark the destination — this is your canonical page for the life of your preparation.

From that page, look for the downloadable exam guide, exam objectives or content outline document. This one document typically resolves most factual questions in a single read, and it is the artefact everything else in your preparation should be checked against.

Know the difference between the certification body and the test-delivery provider

Candidates often conflate two organisations. The certification body (CompTIA, ISACA, Microsoft, AWS) owns the exam content, objectives, scoring and credential. The test-delivery provider (Pearson VUE for many programmes; ISACA lists delivery through PSI centres and remote proctoring) runs the booking, the test centre and the online-proctoring platform. Content questions go to the former; logistics, ID and check-in questions to the latter — and proctoring rules vary by programme even on the same platform, so always read the programme-specific page rather than generic platform advice.

A five-point vetting checklist for any third-party source

Third-party courses, books, videos and communities are where most real learning happens. Before investing time in one, run it through these checks:

1. Does it name the current exam code? A Security+ resource that says SY0-601 rather than SY0-701, or an A+ resource on 220-1101/1102, is built for a retired exam. Match the code against the official page first.
2. Is it dated — and recently? A publication or last-updated date lets you compare against the exam version's launch date. No date at all is itself a warning.
3. Does it map to the official objectives? Quality resources reference the blueprint's domain structure explicitly. If you cannot tell which objectives a chapter covers, coverage gaps are likely.
4. Does it cite the official source for hard facts? Trustworthy authors link prices, formats and policies to vendor pages instead of asserting them.
5. Does it promise what nobody can promise? "Real exam questions", guaranteed passes and claimed pass rates are the signature of sources that will also be careless with everything else. Legitimate practice material tests your understanding of the objectives; it never claims to reproduce the live exam.

A resource can fail one check and survive — a slightly old book against an unchanged exam version may be fine — but two or more failures mean your time is better spent elsewhere.
