The CWNA is the Certified Wireless Network Administrator exam from CWNP, taken by people who plan, deploy and support wireless LANs. This page collects free practice sets by topic, shows how the exam is delivered and scored, and gives a study routine that pairs our questions with the official CWNP material.
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.
The CWNA has 60 questions and takes about 1.5 hours[1] (CWNP, verified Oct 26, 2026).

| WLAN Network Architecture and Design Concepts[4] | 15% | CWNA WLAN Design & Site Survey Practise matching access point placement, channel plans and capacity needs to a stated requirement. |
| WLAN Network Security[4] | 10% | CWNA Wireless Security & Authentication Practise telling authentication methods and encryption options apart and choosing the right one for a scenario. |
| WLAN Protocols and Devices[4] | 20% | CWNA 802.11 Standards & Protocol Architecture Practise amendment features, frame behaviour and medium access rules, and what each device type does. |
| WLAN Regulations and Standards[4] | 20% | CWNA Regulatory Frameworks & Compliance Practise which body sets which rule, what unlicensed operation requires and how violations are handled. |

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.
Question: Which 802.11 amendment was the first to introduce channel bonding, combining two 20 MHz channels into a 40 MHz channel?
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.
Question: What mechanism does 802.11 use to avoid collisions in the shared wireless medium?
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.
Question: Which FCC enforcement action can result from operating a Wi-Fi device that causes harmful interference?
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.
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.
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.
The exam has 60 multiple-choice and multiple-answer questions, and you have 90 minutes. Some questions ask for more than one answer, so read each prompt for how many choices it wants before you select anything.
You need 70% or higher to earn the certification. Instructors must reach 80% or higher. CWNP sets these thresholds, so check the CWNA page on cwnp.com for the current requirement before you book.
No. There are no prerequisites. CWNP does highly recommend the CWSS and CWTS certifications, and they can help if you are new to wireless, but you can register for the CWNA without them.
Yes. You can sit the exam online with CWNP Remote Proctored Exams or in person at a Prometric test center. After you pass, the certificate uploads to your CWNP account within 24 to 72 hours.
You must wait 10 days between attempts, and Saturdays and Sundays count toward those days. Use the wait to review the content areas where you were weakest, then retake practice sets before booking again.
The certification is valid for 3 years. To renew, pass CWSP, CWDP or CWAP before it expires, or retake the current version of the CWNA. Confirm the details on the CWNP site, since exam versions change.
