CWNA Professional Standards & Competencies 5 — Questions and Answers
Question 1: A CWNA professional discovers that a client's WLAN deployment violates local regulatory transmit power limits. What is the appropriate first action?
- Continue operation since the violation is minor
- Notify the client and recommend corrective action to achieve compliance (Correct answer)
- Increase power further to improve performance
- Contact the FCC anonymously
Correct answer: Notify the client and recommend corrective action to achieve compliance
Regulatory compliance is a professional obligation; the CWNA must notify the client of the violation and recommend corrective measures to bring the network into compliance.
Question 2: Which CWNA competency is exercised when defining Quality of Service (QoS) policies to prioritize voice traffic on a wireless network?
- Physical security assessment
- WLAN design and performance optimization (Correct answer)
- Antenna theory calculation
- Vendor certification management
Correct answer: WLAN design and performance optimization
Designing QoS policies to prioritize latency-sensitive applications like voice is part of WLAN design and performance optimization competency.
Question 3: When a client requests that their WLAN support both corporate devices and guest devices simultaneously, what design concept does the CWNA apply?
- Single SSID with open authentication
- Network segmentation using multiple SSIDs and VLANs (Correct answer)
- Disabling all security to maximize compatibility
- Using only 2.4 GHz band for all clients
Correct answer: Network segmentation using multiple SSIDs and VLANs
Multiple SSIDs mapped to separate VLANs provide network segmentation, isolating guest traffic from corporate traffic while allowing both to operate on the same physical infrastructure.
Question 4: A CWNA professional is mentoring a junior technician. Which behavior BEST models ethical professional standards?
- Withholding technical knowledge to maintain competitive advantage
- Sharing accurate information, citing sources, and encouraging certification study (Correct answer)
- Taking sole credit for team accomplishments
- Recommending unnecessary equipment to increase project billing
Correct answer: Sharing accurate information, citing sources, and encouraging certification study
Ethical professionals share knowledge, cite sources accurately, and support the development of colleagues, contributing to the advancement of the profession.
Question 5: What is the purpose of a WLAN capacity analysis performed by a CWNA professional?
- To determine how many VLANs are needed for routing
- To ensure the network can support the expected number of clients and traffic load (Correct answer)
- To measure the physical cable lengths in the building
- To validate DNS server response times
Correct answer: To ensure the network can support the expected number of clients and traffic load
Capacity analysis evaluates whether the WLAN infrastructure can handle anticipated client density and bandwidth demands without degradation.
Question 6: Which document should a CWNA professional reference to understand the specific exam domains and their weighting for the CWNA-109 exam?
- IEEE 802.11-2020 standard
- CWNP CWNA exam objectives document (Correct answer)
- Wi-Fi Alliance certification guide
- CompTIA Network+ study guide
Correct answer: CWNP CWNA exam objectives document
The official CWNP CWNA exam objectives document defines all exam domains, subtopics, and their percentage weighting for the current exam version.
Question 7: A CWNA professional is asked to assess whether a warehouse WLAN meets the requirements for a new barcode scanning application. What is this type of assessment called?
- Security penetration test
- Application-driven requirements analysis (Correct answer)
- Passive RF survey
- Antenna gain measurement
Correct answer: Application-driven requirements analysis
An application-driven requirements analysis evaluates whether the existing WLAN infrastructure meets the specific performance, coverage, and roaming requirements of a new application.
