CWNA Practice Test

What the CWNA is and how it works

According to CWNP, “To earn a CWNA certification, you must take the CWNA exam at CWNP Remote Proctored Exams and pass with a 70% or higher. Instructors must pass with a 80% or higher.”^[1]

CWNA is the entry-level administrator certification in the CWNP wireless track. It tests whether you understand how radio frequency behaves, how 802.11 networks are built and secured, and which rules govern their use. The exam has 60 multiple-choice and multiple-answer questions and a time limit of 90 minutes.

You can sit the exam online through CWNP Remote Proctored Exams or in person at a Prometric test center. There are no prerequisites. CWNP highly recommends the CWSS and CWTS certifications first, but they are not required.

The passing score is 70%. Instructors must reach 80%. After you pass, your certificate uploads to your CWNP account within 24 to 72 hours. If you do not pass, there is a 10-day wait before the next attempt, and weekends count toward those days.

The certification is valid for 3 years. To renew, pass CWSP, CWDP or CWAP before it expires, or retake the current CWNA. The last day to take the CWNA-109 exam is December 31, 2026. Check the CWNP certification page for the current exam version before you book, because versions change.

Our questions are written by us with AI tools and are not real exam questions. Use them to find weak areas, and rely on CWNP for the official objectives.

CWNA content outline and where to practise each area

The content areas below are copied from the official CWNA content outline published by CWNP, with the share of the exam each area carries. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through CWNA questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: Which 802.11 amendment was the first to introduce channel bonding, combining two 20 MHz channels into a 40 MHz channel?

1. 802.11a
2. 802.11g
3. 802.11n
4. 802.11ac

Answer: C. 802.11n

Explanation:

The answer is 802.11n. It introduced channel bonding, joining two 20 MHz channels into a 40 MHz channel to raise throughput. 802.11a and 802.11g are wrong because they work with a single 20 MHz channel and have no bonding. 802.11ac is wrong for this question because it extended wider channels later; the question asks which amendment introduced bonding, not which uses it.

The rule to remember: when a question asks which amendment was the first to add a feature, place the amendments in release order and choose the earliest one that has the feature. Later amendments usually build on it, so they appear as tempting distractors.

Example 2

Question: What mechanism does 802.11 use to avoid collisions in the shared wireless medium?

1. CSMA/CD
2. CSMA/CA
3. Token ring
4. TDMA

Answer: B. CSMA/CA

Explanation:

The answer is CSMA/CA, carrier sense multiple access with collision avoidance. A wireless radio cannot reliably transmit and listen at the same moment, so it cannot detect a collision as it happens. It avoids them by sensing the medium and deferring before it sends. CSMA/CD is wrong because collision detection belongs to wired Ethernet. Token ring is wrong because it is a wired technology that passes a token around a ring. TDMA is wrong because it assigns fixed time slots, which is not how 802.11 shares the medium.

The rule to remember: wired Ethernet detects collisions, while 802.11 avoids them.

Example 3

Question: Which FCC enforcement action can result from operating a Wi-Fi device that causes harmful interference?

1. Notice of Apparent Liability (NAL) for forfeiture
2. Automatic revocation of all FCC licenses held
3. Criminal prosecution under Part 15 statutes
4. Mandatory recall of all devices of the same model

Answer: A. Notice of Apparent Liability (NAL) for forfeiture

Explanation:

The answer is a Notice of Apparent Liability for forfeiture. When a device causes harmful interference, the FCC's usual enforcement tool is a proposed monetary penalty. Automatic revocation of all licenses is wrong because Wi-Fi gear normally operates unlicensed under Part 15, and revocation is not automatic. Criminal prosecution is wrong because it is not the primary mechanism for these violations. A mandatory recall of every device of the same model is wrong because enforcement targets the operator or party responsible, not a blanket recall.

The rule to remember: unlicensed devices must not cause harmful interference, and the typical consequence of breaking that is a financial penalty, not loss of every license.

How to use these practice tests

Start with the official CWNP exam objectives and mark each content area as strong, shaky or unfamiliar. Weight your time toward WLAN Protocols and Devices and WLAN Regulations and Standards, since they carry the largest share of the outline, but do not skip the smaller areas.

1. Take a short set on a shaky area, such as RF fundamentals, before you read about it. The misses show you what to study.
2. Read the matching official material, then retake the set and compare.
3. For every miss, write down the rule behind the right answer in your own words, not just the letter.
4. Move to wireless security, 802.11 standards and regulations in the same way.
5. Finish with mixed sets such as the MCQ set under a timer that matches the real limit of 90 minutes.

Some set titles on this page, such as the stakeholder and research sets, are broader than the official outline, so treat them as extra reading practice. Our questions are not real exam questions, so a good score here shows understanding of the topic, not a predicted result.
