KNX Basic course exam questions with answers

For the standard Basic course, the theory paper contains 100 true/false statements in 90 minutes. Scoring is +1 for correct, −0.5 for incorrect and 0 for unanswered. See the KNX exam regulations.

For example, 65 correct, 20 incorrect and 15 unanswered give 55 points, not 65. This worked calculation explains why the number of correct answers and the final score can differ.

The standard Basic course includes supervised theory and practical examinations; each requires at least 50%. Confirm arrangements with your training centre. Online practice supplements your course and practical work.

Read each statement before revealing the answer to yourself. After checking it, try explaining the rule without rereading the correction.

Example 1 — Reading an individual address

True or false? The individual address 2.4.18 identifies device 18 on line 4 in area 2.

True. Read the parts as area.line.device. They do not represent building, floor and room. Official address notation.

Example 2 — Understanding a group address

True or false? A group address identifies one physical device and cannot link objects from different devices.

False. Group addresses create logical links between group objects. Their role differs from identifying a device's position in the topology. Official explanation of group addresses.

These examples test one distinction from two directions. Getting both right once is a useful start; explaining a differently worded statement later is a better revision check. Explore more corrected questions.

The official Basic course documentation catalogue lists ETS6 Professional, system arguments, system overview, topology, bus devices, KNX RF and TP installation.

Use those headings to organise your notes. Under each, write one question you still need to resolve and the course page or exercise that will help you resolve it. Leave unfamiliar headings visible rather than counting them as covered.

Our suggested check is practical: can you explain the term, apply it to an example and recognise when the example changes? For a numeric limit, record what it limits and the conditions attached to it. For an ETS task, connect the vocabulary to an action you have performed during training.

The topic index helps you find relevant public explanations. Its organisation is a revision aid, not a prediction of how many questions each subject will receive in your examination. Use your tutor's programme to settle the required scope.

You can use CertifBus in three ways.

• Read a public correction: the question library contains individual pages that you can revisit at the same address.
• Try a short session: Learn mode gives you 10 free questions without an account or payment card. The daily selection rotates by UTC day, with questions spread across topic blocks. Different days can share questions.
• Prepare with full access: the paid Basic plans open the full Basic practice library, including true/false and multiple-choice learning exercises, targeted review and full-length mock exams.

The free timed session remains a short preview when you do not have an active full-access plan. It is not the complete examination simulation. With full access, a Basic mock contains 100 true/false questions and runs for 90 minutes.

Compare access durations and current prices. Choose the duration around your preparation window; the published solo plans use a single payment without automatic renewal.

A correction is most useful when it changes what you do next. Try this revision routine.

Name the confusion

Write one sentence about the mistake: “I confused the address of the device with the link between its objects.” Avoid the less useful note “I need to revise everything.” If you answered correctly by guessing, mark the uncertainty in your own notes too.

Check the explanation

Find the relevant passage in your course material. Describe the rule in your own words and sketch an example if that helps. If a correction seems inconsistent, keep its question ID and ask for clarification through contact. A disagreement deserves checking before you memorise either answer.

Return with a different formulation

Revisit the topic after a break. Try another question before rereading the first answer. This lets you see whether you can use the idea outside the wording you already remember.

A short quiz provides examples of mistakes, not a reliable judgement of your readiness. Your personal progress page can help organise recorded practice when you are signed in. A full timed mock answers a different question: how you manage a complete session and its scoring. Review its mistakes before simply starting another.

For an introduction to KNX and working with ETS6, the official ETS6 eCampus provides a starting point. For course preparation, use the edition of the documentation supplied or recommended by your centre.

A PDF, flashcard or website can be useful if you can identify its author, scope and references. Check a sample explanation: does it show the condition that makes the statement true or false? Can you verify an unfamiliar term? Does it distinguish practice from an official examination? The format of the file alone cannot answer these questions.

For CertifBus, read how questions and sources are handled, then judge the experience using the free session. No large purchase or account setup is needed to inspect a correction.

If you want a longer routine, use the Basic preparation guide. If you are ready to practise, start the free questions. When the explanations fit your needs, choose your full-access duration.
