What do I need to have before I can take the CWDP-305 exam?

You must hold a current and valid CWNA certification. The CWNA is the foundational certification for the CWNP program and is a prerequisite for all professional-level exams including CWDP-305.

How hard is the CWDP-305 compared to the CWNA exam?

CWDP-305 is a professional-level exam that requires deeper technical knowledge and practical application skills than the CWNA. It focuses on design decisions and real-world scenarios rather than foundational concepts, making it significantly more challenging.

How long does it typically take to prepare for CWDP-305?

Preparation time varies based on your wireless design experience, but most candidates spend 100 to 200 hours studying. Those with hands-on design experience may need less time, while those new to design projects typically need more.

What is the hardest part of the CWDP-305 exam and how should I approach it?

The Design the WLAN domain accounts for 40 percent of the exam and is the most heavily weighted section. Focus on understanding design methodologies, RF planning tools, and how to translate business and technical requirements into concrete design recommendations.

What happens on exam day for CWDP-305?

You will have 90 minutes to answer 60 multiple choice questions delivered either online through CWNP Remote Proctored Exams or in-person at a Prometric testing centre. You need to score 70 percent or higher to pass, though instructors must score 80 percent or higher.

Can I retake the CWDP-305 exam if I don't pass?

Yes, you can retake the exam, but you must purchase another exam voucher for each attempt. The voucher is valid for two years from purchase date, giving you time to study and try again.

How long is the CWDP certification valid?

The CWDP certification is valid for three years. To recertify, you must maintain a current CWNA certification and pass the current CWDP exam, which also renews your CWNA for another three years.

What job role does CWDP-305 prepare me for?

CWDP-305 is designed for network engineers, architects, and IT professionals who plan, design, and deploy enterprise wireless LANs. It validates your ability to move from networking roles into specialized wireless design positions.

Where does CWDP-305 fit in the CWNP certification track?

CWDP is one of three professional-level certifications in the CWNP program, alongside CWSP (Security) and CWAP (Analysis). All three require a current CWNA first, and all three count toward the CWNE expert-level certification.

Can I schedule the CWDP-305 exam online or do I have to go to a test centre?

You can choose either option. CWNP now offers remote proctored exams for convenience, or you can test in-person at any Prometric testing centre worldwide. Both methods use the same exam and passing requirements.

Question 1 Domain 1Define Specifications for the WLAN

What kind of site survey helps you identify if roaming is working as designed?

APassive

BPredictive

CActive

DSpectrum analysis walkthrough

Correct Answer: C

Explanation WPA/WPA2-Enterprise provides stronger security through backend authentication servers but introduces complexity absent in Personal mode. Enterprise requires RADIUS or similar infrastructure that Personal does not need. It also demands more administrative work to configure user accounts, certificates, and server settings. Personal mode uses a simple pre-shared key, making it easier to deploy but less scalable for larger organizations with many users.

Question 2 Domain 2Design the WLAN

Aesthetics are critical in some environments. What common installation technique can best meet this requirement in a stadium while not voiding manufacturer warranties?

APainting to match team colors

BUsing enclosures under the seats

CMounting on a non-fixed pole

DMounting on the walls

Correct Answer: B

Explanation Accurate attenuation measurements require a controlled comparison method. You first establish a baseline by measuring RSSI in free space with the AP and measuring device 5 meters apart. Then you position the AP 4 meters from the material on one side and the measuring device 0.67 meters from the material on the other side. The difference between this measurement and your baseline tells you exactly how much the material attenuates the signal. This method isolates the material's effect without interference from surrounding environment.

Question 3 Domain 2Design the WLAN

When preparing a floor plan graphic for use in predictive and manual site surveying, what calibration method will lead to the most accurate and

reliable RF data?

AUse the known size of a small object, such as a ceiling tile, and use a single instance of this object (e.g. a single ceiling tile) to scale the
floor plan.

BMeasure the width of an actual office doorway with a tape measure and use this value to calibrate against a doorway graphic.

CUse the longest available measurement (like a straight exterior wall) to calibrate the graphic's scale.

DCalibrate the ceiling height of the floor plan first, then the survey software should be able to auto-calibrate the X and Y planes of the
graphic.

Correct Answer: C

Question 4 Domain 1Define Specifications for the WLAN

You are designing a WLAN and nave been asked to recommend a security solution for the network The organization requires that 802 1X/EAP be implemented, but they do not have a PKI and do not wish to deploy one They suggest that mostly Windows clients. Apple phones and Android phones will be used What do you recommend?

AUse CCMP AES with a PSK

BUse EAP-PEAP for the authentication solution

CUse FAP-TLS for the authentication solution

DUse TKIPRC4 with a PSK

Correct Answer: B

Explanation DFS channels require the infrastructure to monitor for radar signals and vacate the channel within specific time limits when radar is detected. Airports have significant radar systems operating in the 5 GHz band. Using DFS channels near airport radar would cause constant channel switching and network instability as the equipment detects radar and abandons channels repeatedly. This makes DFS unsuitable for airport environments where reliability and consistent channel access matter greatly for operations.

Question 5 Domain 1Define Specifications for the WLAN

You are testing a VoWLAN deployment, and your communication measurements show a certain amount of lost packets. What would be an

acceptable packet error rate value to still provide acceptable call quality?

AThere should be 0% error in a VoWLAN type of deployment

BNo more than 1% PER max should be acceptable

CNo more than 4% PER max should be acceptable

DNo more than 8% PER max should be acceptable

Correct Answer: D

Explanation Barcode scanners transmit brief data bursts containing the scanned information. They do not require continuous high-speed connections or large data transfers. A barcode typically encodes minimal information that moves quickly across the network. This makes barcode scanners low-throughput devices compared to other applications like video streaming or large file transfers. Understanding device throughput requirements helps determine the WLAN capacity and channel bandwidth needed during the specification gathering phase.
