Question 1Exam objectives and certification scope

Which organization develops and maintains the CWNP certification program, including the Certified Wireless Network Administrator (CWNA) credential?

  1. The FCC, through its equipment authorization rules
  2. The CWNP program, an independent vendor-neutral certification body Correct answer.
  3. The Wi-Fi Alliance, through its interoperability testing program
  4. The IEEE 802.11 working group, through its standards process

Explanation

CWNP certifications are administered by the CWNP program, which positions itself as vendor-neutral and independent of any single equipment maker. The Wi-Fi Alliance certifies interoperability, the IEEE writes the 802.11 standards, and the FCC regulates radio equipment, so none of those bodies issues the CWNA credential.

Question 2Exam objectives and certification scope

A candidate is preparing for the CWNA certification. Which statement best describes the intended scope of the CWNA exam?

  1. Cable plant installation and structured cabling certification
  2. Vendor-neutral wireless LAN fundamentals, including RF, 802.11, security, and site surveying Correct answer.
  3. Cellular core network planning and 5G radio access engineering
  4. Configuration of one specific vendor's controller and access point command line

Explanation

The CWNA exam targets vendor-neutral WLAN fundamentals such as radio frequency behavior, 802.11 operation, security, and site survey concepts. It is deliberately not tied to a single vendor's product interface, and it does not cover cellular core engineering or copper cabling installation.

Question 3Exam objectives and certification scope

What is the primary purpose of the CWNP certification track as described by the program?

  1. To certify that hardware passes regulatory emission limits
  2. To guarantee employment with a specific wireless equipment manufacturer
  3. To replace the IEEE 802.11 standards development process
  4. To validate vendor-neutral WLAN knowledge across a progressive series of certifications Correct answer.

Explanation

The CWNP track is structured as a progressive set of vendor-neutral certifications that validate WLAN knowledge at increasing depth. It does not guarantee employment, does not replace standards work, and is not a hardware regulatory certification.

Question 4Exam objectives and certification scope

Which credential in the CWNP track is widely described as the entry-level or foundational wireless certification?

  1. CWNA Correct answer.
  2. CWSP
  3. CWDP
  4. CWAP

Explanation

The CWNA is the foundational credential in the CWNP track, covering vendor-neutral WLAN fundamentals. The other credentials build on that base with specialized focus areas.

Question 5Exam objectives and certification scope

A candidate wants to specialize in wireless security analysis and 802.1X/EAP deployments. Which CWNP certification most directly targets that specialization?

  1. CWSP Correct answer.
  2. CWAP
  3. CWNA
  4. CWDP

Explanation

The CWSP (Certified Wireless Security Professional) is the CWNP credential aimed at wireless security, including authentication frameworks such as 802.1X and EAP. CWNA is foundational, CWDP addresses design, and CWAP addresses analysis.

Question 6Exam objectives and certification scope

Which CWNP credential is most closely associated with WLAN design methodology, requirements gathering, and predictive and validation surveys?

  1. CWAP
  2. CWNA
  3. CWDP Correct answer.
  4. CWSP

Explanation

The CWDP (Certified Wireless Design Professional) centers on design methodology, including requirements collection and predictive and validation survey work. Security, analysis, and foundational topics map to the other credentials.

Question 7Exam objectives and certification scope

Which CWNP certification focuses on protocol capture analysis, frame exchanges, and advanced WLAN troubleshooting?

  1. CWAP Correct answer.
  2. CWSP
  3. CWNA
  4. CWDP

Explanation

The CWAP (Certified Wireless Analysis Professional) targets frame-level analysis, protocol captures, and troubleshooting of WLAN behavior. Design, security, and foundational coverage belong to the other credentials.

Question 8Exam objectives and certification scope

Which statement correctly describes the relationship between CWNP certifications and equipment vendors?

  1. They are issued jointly by the major enterprise WLAN vendors
  2. They are vendor-neutral and not tied to any single manufacturer's products Correct answer.
  3. They require candidates to hold a vendor-specific administrator certificate first
  4. They certify only products that pass interoperability testing

Explanation

CWNP credentials are designed as vendor-neutral, so the knowledge applies regardless of which manufacturer's equipment is deployed. They are not co-issued by vendors, do not require a vendor prerequisite, and do not certify products.

Question 9Exam objectives and certification scope

A hiring manager sees 'CWNA' on a resume. What does that credential most reliably indicate about the candidate?

  1. Completion of a cellular network optimization program
  2. Hands-on certification on one vendor's cloud controller platform
  3. A license to install commercial radio transmitters
  4. Validated vendor-neutral knowledge of wireless LAN fundamentals Correct answer.

Explanation

CWNA signals validated, vendor-neutral WLAN fundamentals rather than product-specific or regulatory authority. It is not a vendor platform certification, a transmitter license, or a cellular program.

Question 10Exam objectives and certification scope

A candidate asks whether passing the CWNA exam makes them a CWNP. Which answer is most accurate?

  1. Passing CWNA confers every CWNP certification at once
  2. Passing CWNA authorizes the holder to teach CWNP courses
  3. Passing CWNA earns the CWNA credential, one certification within the broader CWNP program Correct answer.
  4. Passing CWNA has no standing until a vendor certificate is also earned

Explanation

CWNA is a single credential within the CWNP program; other credentials such as CWSP, CWDP, and CWAP are earned separately. Passing CWNA does not confer all certifications, does not depend on a vendor certificate, and does not authorize instruction.

Question 11Exam objectives and certification scope

Which topic area is most clearly within the published scope of the CWNA exam rather than an advanced CWNP credential?

  1. Performing a frame-level analysis of a 4-way handshake capture
  2. Basic RF mathematics such as converting between mW and dBm Correct answer.
  3. Engineering a guest network 802.1X/EAP policy for a large enterprise
  4. Designing a multi-floor predictive survey for a hospital campus

Explanation

Basic RF math, including the mW-to-dBm relationship, is foundational material covered at the CWNA level. Predictive survey design, frame-level capture analysis, and enterprise security policy engineering align with the advanced design, analysis, and security credentials.

Question 12Exam objectives and certification scope

A candidate plans study time and wants to know how the CWNP track is generally structured. Which description is most accurate?

  1. A vendor ladder that begins with a specific manufacturer's associate exam
  2. Four equally weighted credentials with no prerequisite relationships
  3. A single exam that awards all wireless certifications at once
  4. A foundational credential followed by specialized credentials in security, design, and analysis Correct answer.

Explanation

The track is commonly described as a foundational CWNA credential followed by specialized credentials covering security, design, and analysis. It is not a single all-in-one exam, not a vendor ladder, and the credentials are not simply interchangeable equivalents.

Question 13Exam objectives and certification scope

Why does a vendor-neutral certification such as CWNA remain useful when an organization changes WLAN vendors?

  1. The certification is tied to the 802.11 standard revision rather than to products
  2. The underlying RF and 802.11 concepts transfer across vendors, even though product interfaces differ Correct answer.
  3. The certification requires retesting only when the vendor changes
  4. The certification automatically re-issues for the new vendor's platform

Explanation

Vendor-neutral certification emphasizes concepts such as RF behavior and 802.11 operation that remain valid across manufacturers, while product-specific interfaces change. The credential is not automatically re-issued, does not require vendor-change retesting, and is not tied to a single standards revision.

Question 14Exam objectives and certification scope

A candidate is deciding between a vendor-specific WLAN certification and CWNA. Which consideration is most consistent with the CWNA program's positioning?

  1. CWNA certifies hardware interoperability rather than individual knowledge
  2. CWNA replaces the need for any hands-on product training
  3. CWNA is only recognized by a single equipment manufacturer
  4. CWNA emphasizes concepts that apply across multi-vendor environments, while vendor certifications target one product line Correct answer.

Explanation

CWNA is positioned around cross-vendor concepts, which suits multi-vendor environments, whereas vendor certifications focus on one product line. CWNA is not limited to one manufacturer, does not replace hands-on product training, and does not certify hardware.

Question 15Exam objectives and certification scope

Which pairing of CWNP credential and primary focus area is correct?

  1. CWDP and protocol capture analysis
  2. CWAP and WLAN design methodology
  3. CWNA and advanced security engineering
  4. CWSP and wireless security Correct answer.

Explanation

CWSP is the security-focused credential, so pairing it with wireless security is correct. The other pairings mismatch the credentials with the focus areas of design, analysis, and foundational knowledge.

Question 16Exam objectives and certification scope

An employer wants a candidate who can both explain 802.11 fundamentals and later specialize in troubleshooting frame exchanges. Which sequence of CWNP credentials best matches that path?

  1. CWSP first, then CWDP
  2. CWNA first, then CWAP Correct answer.
  3. CWAP first, then CWNA
  4. CWDP first, then CWSP

Explanation

The natural path is the foundational CWNA followed by the analysis-focused CWAP for frame-level troubleshooting. Starting with an advanced credential before the foundation, or choosing security and design credentials, does not match the stated goal.

Question 17Exam objectives and certification scope

A study group claims that CWNP exams are written by equipment manufacturers to promote their products. Which response is most accurate?

  1. The claim is correct, which is why each exam names a preferred vendor
  2. The program is vendor-neutral and independent, so the exams are not written to promote a manufacturer's products Correct answer.
  3. The claim is correct, but only for the security credential
  4. The exams are written by the IEEE to promote the 802.11 standard

Explanation

CWNP positions itself as an independent, vendor-neutral certification program, so its exams are not designed to promote a particular manufacturer. They are not vendor-endorsed product promotions, not selectively vendor-driven for one credential, and not authored by the IEEE.

Question 18Exam objectives and certification scope

Which statement about the CWNA exam's technical depth is most accurate?

  1. It tests working knowledge of WLAN fundamentals rather than expert-level design or analysis specialization Correct answer.
  2. It tests only regulatory compliance for radio transmitters
  3. It tests cellular and WLAN convergence engineering
  4. It tests expert-level frame analysis equivalent to the analysis credential

Explanation

CWNA establishes working knowledge of WLAN fundamentals and serves as the base for specialized credentials. It does not reach the expert analysis depth of CWAP, does not focus on regulatory transmitter compliance, and does not cover cellular convergence engineering.

Question 19Exam objectives and certification scope

A candidate holds CWNA and wants to deepen expertise specifically in predictive and on-site survey methodology. Which CWNP credential should they pursue next?

  1. A second CWNA attempt
  2. CWSP
  3. CWAP
  4. CWDP Correct answer.

Explanation

Survey methodology, including predictive and validation surveys, is central to the design credential CWDP. CWAP targets analysis, CWSP targets security, and retaking CWNA does not add design specialization.

Question 20Exam objectives and certification scope

Which scenario best illustrates the practical value of vendor-neutral WLAN certification during a merger of two companies using different WLAN vendors?

  1. Staff can use the certification to certify both vendors' hardware as interoperable
  2. Staff must recertify with the CWNP program for each vendor involved
  3. Staff can apply shared RF and 802.11 concepts to both environments while learning each vendor's tools Correct answer.
  4. Staff can rely on the certification to configure either vendor's controller without training

Explanation

Vendor-neutral certification supplies transferable concepts that staff can apply in both environments while they learn each vendor's specific tools. It does not require recertification per vendor, does not substitute for product training, and does not certify hardware interoperability.

Question 21Exam objectives and certification scope

A training plan lists CWNA, CWSP, CWDP, and CWAP as if they were interchangeable. What is the most significant error in that plan?

  1. It ignores that all four are the same exam offered under different names
  2. It ignores that only the security credential requires an exam
  3. It ignores that each credential has a distinct specialization and depth, with CWNA as the foundation Correct answer.
  4. It ignores that the design credential is issued by the IEEE

Explanation

The credentials are not interchangeable: CWNA is foundational, while CWSP, CWDP, and CWAP each target security, design, and analysis respectively. They are separate exams rather than aliases, all require exams, and none is issued by the IEEE.

Question 22Exam objectives and certification scope

A candidate argues that because CWNA is vendor-neutral, it cannot help with multi-vendor roaming problems. Which evaluation of that argument is most defensible?

  1. The argument is weak, because CWNA certifies vendor interoperability of hardware
  2. The argument is weak, because vendor-neutral 802.11 and RF concepts underlie roaming behavior across vendors Correct answer.
  3. The argument is strong, because roaming is defined only by each vendor's proprietary protocol
  4. The argument is strong, because vendor-neutral exams avoid all client behavior topics

Explanation

Roaming behavior rests on shared 802.11 and RF principles, so vendor-neutral knowledge is directly useful in multi-vendor troubleshooting. Roaming is not defined solely by proprietary protocols, the exams do address client behavior, and CWNA does not certify hardware interoperability.

Question 23Exam objectives and certification scope

An organization wants assurance that its staff understand both security policy and design trade-offs before deploying a new WLAN. Which combination of CWNP credentials most directly addresses those two areas?

  1. CWAP and CWNA
  2. CWDP and CWAP
  3. CWSP and CWDP Correct answer.
  4. CWNA and CWAP

Explanation

Security policy maps to CWSP and design trade-offs map to CWDP, so that pairing covers both stated needs. The other combinations omit one of the two required areas or substitute unrelated specializations.

Question 24Exam objectives and certification scope

Which statement best explains why the CWNP track separates design, security, and analysis into distinct credentials rather than one exam?

  1. Each specialization requires depth that a single foundational exam cannot reasonably cover Correct answer.
  2. The credentials are separated only to increase total exam fees
  3. The separation reflects different standards bodies owning each area
  4. The specializations are legally required to be licensed separately

Explanation

Specialized credentials allow deeper coverage of design, security, and analysis than one foundational exam could provide. The separation is not a fee strategy, not a legal licensing requirement, and not a reflection of different standards bodies.

Question 25Exam objectives and certification scope

A candidate reads that CWNP certifications are 'vendor-neutral' and concludes they have no practical product relevance. Which counterpoint is most accurate?

  1. Vendor-neutral exams are purely theoretical and exclude any product context
  2. Vendor-neutral concepts are the basis for configuring and troubleshooting real products from any manufacturer Correct answer.
  3. Vendor-neutral exams are written by manufacturers but branded neutrally
  4. Vendor-neutral certification requires a vendor sponsorship to remain valid

Explanation

Vendor-neutral knowledge provides the conceptual basis for working with real products from any manufacturer, which is its practical relevance. The exams are not purely theoretical, do not require vendor sponsorship, and are not manufacturer-written under neutral branding.

Question 26Exam objectives and certification scope

Which CWNP credential is earned first and serves as the entry point to the professional-level WLAN certifications?

  1. CWDP
  2. CWAP
  3. CWSP
  4. CWNA Correct answer.

Explanation

CWNA is the foundational credential in the CWNP track and is a prerequisite for the professional-level exams. The other three are professional-level credentials that build on the fundamentals covered by CWNA.

Question 27Exam objectives and certification scope

An employer's job posting requires 'CWNP certification' for a wireless engineer role. Which interpretation of that requirement is most accurate?

  1. The candidate must hold every credential in the CWNP program
  2. The candidate must hold a vendor-specific certification from a WLAN equipment maker
  3. The candidate must have completed a CWNP-authorized instructor-led course
  4. The candidate must hold at least one credential from the CWNP program Correct answer.

Explanation

CWNP is the name of the certification program, not a single exam, so requiring 'CWNP certification' means holding one or more of its credentials. A posting that demands a specific level would name it, such as CWNA or CWSP. Vendor certifications and instructor-led training are separate from holding a CWNP credential.

Question 28Exam objectives and certification scope

A network team must document how 802.11 management, control, and data frames behave during roaming on a multi-vendor network, and the work requires deep protocol capture analysis. Which credential aligns best with that deliverable?

  1. CWSP
  2. CWDP
  3. CWNA
  4. CWAP Correct answer.

Explanation

CWAP targets protocol analysis, frame exchanges, and advanced troubleshooting, which matches a frame-level roaming investigation. CWNA covers fundamentals rather than deep capture analysis, CWSP centers on security, and CWDP centers on design and survey work.

Question 29Exam objectives and certification scope

A candidate has passed CWNA and now wants to specialize in gathering requirements and producing predictive and on-site survey designs. Which next credential fits that goal?

  1. CWDP Correct answer.
  2. CWAP
  3. CWSP
  4. A repeat sitting of CWNA

Explanation

CWDP is the design-focused credential, covering requirements gathering and predictive and on-site survey methodology. CWSP and CWAP address security and analysis respectively, and retaking CWNA does not add a design specialization.

Question 30Exam objectives and certification scope

A team must secure a WLAN rollout that spans two recently merged companies with different vendors, and leadership wants staff who can reason about security policy and design trade-offs before deployment. Which combination of CWNP credentials best matches that need?

  1. CWNA and CWAP
  2. CWAP and a vendor-specific security certificate
  3. CWSP and CWDP Correct answer.
  4. CWNA and a second sitting of CWNA

Explanation

CWSP supplies the security-policy depth and CWDP supplies the design trade-off expertise, which together cover the pre-deployment assurance leadership wants. CWNA and CWAP emphasize fundamentals and post-deployment analysis, and vendor-specific certificates do not provide vendor-neutral coverage across both merged environments.

Question 31Core concepts and terminology

In wireless LAN terminology, what does the acronym SSID identify?

  1. The MAC address burned into an access point radio
  2. The encryption key used by WPA2-Personal
  3. The channel width negotiated during association
  4. The name of a basic service set or extended service set Correct answer.

Explanation

The service set identifier is the human-readable network name that distinguishes one WLAN from another. Clients scan for and select an SSID during association, and multiple access points can share one SSID to form an extended service set.

Question 32Core concepts and terminology

A client roams between two access points that publish the same network name but have different BSSIDs. Which statement describes what the client has done?

  1. It renegotiated its IP address from a different DHCP scope
  2. It changed from infrastructure mode to ad hoc mode
  3. It moved between two basic service sets within one extended service set Correct answer.
  4. It downgraded from a 5 GHz channel to a 2.4 GHz channel

Explanation

Each access point radio defines a basic service set identified by its own BSSID. When several BSSIDs share one SSID they belong to the same extended service set, and moving between them is roaming rather than joining a new network.

Question 33Core concepts and terminology

Which organization develops and publishes the 802.11 family of wireless LAN standards?

  1. IETF
  2. ITU-R
  3. Wi-Fi Alliance
  4. IEEE Correct answer.

Explanation

The Institute of Electrical and Electronics Engineers publishes the 802.11 amendments that define wireless LAN operation. The Wi-Fi Alliance certifies interoperability against those standards but does not author them.

Question 34Core concepts and terminology

What is the primary role of the Wi-Fi Alliance in the wireless industry?

  1. Defining the MAC frame format used on the air interface
  2. Certifying that products interoperate with ratified 802.11 standards Correct answer.
  3. Allocating unlicensed spectrum bands to national regulators
  4. Assigning OUI prefixes to access point manufacturers

Explanation

The Wi-Fi Alliance operates certification programs such as Wi-Fi CERTIFIED that test products against standards and profile requirements. It does not write the underlying 802.11 standards, allocate spectrum, or issue MAC address prefixes.

Question 35Core concepts and terminology

Which frequency band is commonly used by 802.11 WLANs in most regulatory domains because it requires no individual license?

  1. The 28 GHz licensed millimeter-wave band
  2. The 1.9 GHz licensed PCS band
  3. The 900 MHz cellular uplink band
  4. The 2.4 GHz ISM band Correct answer.

Explanation

The 2.4 GHz industrial, scientific, and medical band is unlicensed in most countries and hosts classic 802.11b/g and later operation. Cellular and millimeter-wave bands cited here require operator licenses.

Question 36Core concepts and terminology

Why does the 2.4 GHz band offer fewer non-overlapping channels than the 5 GHz band in typical deployments?

  1. Its maximum transmit power is lower than that of 5 GHz
  2. Its channels are licensed and must be coordinated with cellular operators
  3. Its total available bandwidth is narrower and each channel occupies a wider relative slice Correct answer.
  4. Its radios cannot perform dynamic frequency selection

Explanation

The 2.4 GHz band provides only about 83 MHz of usable spectrum, so 20 MHz channels overlap heavily and only a few can be used without interference. The 5 GHz band offers far more spectrum, allowing many more non-overlapping channels.

Question 37Core concepts and terminology

What does the term BSSID specifically refer to in an infrastructure WLAN?

  1. The IP subnet assigned to wireless clients
  2. The pairwise key negotiated during the four-way handshake
  3. The MAC address of the access point radio serving the basic service set Correct answer.
  4. The network name configured by the administrator

Explanation

The BSSID is the 48-bit MAC address that uniquely identifies the radio of a basic service set. In an infrastructure network it is normally the access point interface address that clients use when associating.

Question 38Core concepts and terminology

A network engineer wants client traffic to be forwarded by a central controller rather than bridged locally at each access point. Which architecture describes this?

  1. Autonomous access point architecture
  2. Independent basic service set architecture
  3. Ad hoc peer-to-peer architecture
  4. Split MAC with centralized data forwarding Correct answer.

Explanation

In a split-MAC design the access point handles time-sensitive real-time functions while the controller manages management and often data forwarding. Centralizing data forwarding lets policy and mobility be enforced in one place.

Question 39Core concepts and terminology

Which term describes an access point that performs all management and forwarding functions without relying on a wireless controller?

  1. Mesh portal
  2. Controller-based access point
  3. Lightweight access point
  4. Autonomous access point Correct answer.

Explanation

An autonomous, or standalone, access point carries its full configuration and forwarding logic locally. Lightweight access points instead depend on a controller using a CAPWAP-style tunnel for management.

Question 40Core concepts and terminology

Which protocol is commonly used to carry control and data traffic between lightweight access points and a wireless LAN controller?

  1. RADIUS
  2. SNMPv3
  3. CAPWAP Correct answer.
  4. LWAPP over TLS only

Explanation

The Control and Provisioning of Wireless Access Points protocol encapsulates both control and data channels between lightweight APs and controllers. It succeeded the earlier LWAPP and can secure its control channel with DTLS.

Question 41Core concepts and terminology

Which CSMA/CA mechanism helps a station avoid collisions by reserving the medium before sending a data frame?

  1. Block acknowledgement agreement
  2. Dynamic frequency selection
  3. Four-way WPA handshake
  4. Request to Send and Clear to Send exchange Correct answer.

Explanation

The optional RTS/CTS exchange reserves the medium for a defined duration so hidden stations defer transmission. It addresses the hidden node problem that carrier sense alone cannot solve.

Question 42Core concepts and terminology

Why does 802.11 use collision avoidance rather than collision detection as used in wired Ethernet?

  1. The 802.11 standard forbids any form of carrier sensing
  2. Wireless frames are always smaller than the Ethernet minimum frame size
  3. A wireless station cannot reliably detect collisions while transmitting on a shared radio medium Correct answer.
  4. Radio hardware lacks the processing power to compute checksums

Explanation

A transmitting radio cannot easily hear a collision because its own signal dominates the local receiver, and hidden nodes may collide outside its range. Collision avoidance with positive acknowledgements therefore replaces collision detection.

Question 43Core concepts and terminology

What is the purpose of the distributed coordination function in 802.11?

  1. It defines the contention-based access method all stations use by default Correct answer.
  2. It defines the roaming handoff between controllers
  3. It defines the centralized polling schedule used by the point coordinator
  4. It defines the encryption algorithm for the robust security network

Explanation

DCF is the mandatory contention-based medium access method built on carrier sense, interframe spacing, and random backoff. It lets stations compete for the channel without a central scheduler.

Question 44Core concepts and terminology

Which interframe space is shortest and is used for high-priority control responses such as acknowledgements?

  1. DIFS
  2. SIFS Correct answer.
  3. EIFS
  4. PIFS

Explanation

The short interframe space gives immediate control frames priority over contention-based traffic. Because SIFS is shorter than DIFS or PIFS, acknowledgements and CTS responses win the medium without backoff.

Question 45Core concepts and terminology

What is the hidden node problem in a wireless LAN?

  1. A client cannot see the SSID because beacon frames are suppressed
  2. An access point hides its management frames from unauthenticated clients
  3. Two stations can each reach the access point but cannot hear each other, so their transmissions collide Correct answer.
  4. A station is hidden behind a captive portal until it authenticates

Explanation

When stations are out of range of each other but both within range of the AP, carrier sense fails to prevent simultaneous transmission. The resulting collisions at the AP degrade throughput, which is why RTS/CTS exists.

Question 46Core concepts and terminology

Which frame type does an access point transmit to announce an SSID and its capabilities on a regular interval?

  1. Beacon frame Correct answer.
  2. Association request frame
  3. Probe request frame
  4. Authentication frame

Explanation

Beacon frames are broadcast periodically by the AP to advertise the SSID, supported rates, and security capabilities. Clients use them to discover networks and to synchronize their timing.

Question 47Core concepts and terminology

A client sends a probe request with a specific SSID in its information element. What type of scanning is the client performing?

  1. Passive scanning
  2. Directed roaming
  3. Active scanning Correct answer.
  4. Channel sounding

Explanation

Active scanning has the client transmit probe requests and wait for probe responses, which speeds discovery. Passive scanning instead relies on listening for periodic beacons.

Question 48Core concepts and terminology

What distinguishes the 802.11 association process from authentication in an open system?

  1. Association is mandatory only when WPA3 is enabled
  2. Association verifies identity while authentication assigns the channel
  3. Authentication verifies identity while association establishes the binding between client and AP Correct answer.
  4. Both terms describe the same exchange and are used interchangeably

Explanation

Authentication is the initial identity check, and association then creates the logical link that lets the client exchange data through the AP. A client must authenticate before it can associate.

Question 49Core concepts and terminology

Which security standard introduced the robust security network and the four-way handshake to 802.11?

  1. 802.11k
  2. 802.11i Correct answer.
  3. 802.11r
  4. 802.11e

Explanation

The 802.11i amendment defined the robust security network, including the four-way handshake and stronger encryption. It became the basis for WPA2 certification.

Question 50Core concepts and terminology

Which security suite uses SAE to resist offline dictionary attacks during the initial key exchange?

  1. Open system with WEP
  2. WPA2-Personal
  3. WPA3-Personal Correct answer.
  4. WPA-Enterprise

Explanation

WPA3-Personal replaces the pre-shared key handshake with simultaneous authentication of equals, which resists offline guessing of captured handshakes. WPA2-Personal remains vulnerable to offline dictionary attacks on captured four-way handshakes.
