Question 221: Which Cisco AP mode is primarily used to capture wireless frames for detailed packet analysis?

1. Local mode
2. FlexConnect mode
3. Sniffer mode
4. Monitor mode

Correct Answer: 3. Sniffer mode

Explanation:

Sniffer mode is designed to capture wireless packets and forward the captured frames to a designated system for analysis. It is useful when troubleshooting protocol behavior, authentication exchanges, roaming events, or other wireless problems that require detailed packet-level inspection. Local mode provides normal client access, FlexConnect supports distributed branch deployments, and Monitor mode is primarily intended for wireless monitoring functions such as detecting rogue devices. Therefore, Sniffer mode is the appropriate AP operating mode when the primary requirement is capturing wireless frames for protocol analysis.

Question 222: Which Cisco AP mode is primarily intended to detect rogue access points and other wireless threats rather than provide normal client access?

1. Monitor mode
2. Local mode
3. FlexConnect mode
4. Sniffer mode

Correct Answer: 1. Monitor mode

Explanation:

Monitor mode converts an access point into a dedicated wireless monitoring device rather than a normal client-serving AP. In this mode, the AP can scan the RF environment and assist with functions such as rogue AP detection and other wireless security monitoring activities. Local mode is used for normal wireless client access, FlexConnect provides distributed forwarding capabilities, and Sniffer mode is intended for packet capture. Therefore, Monitor mode is the appropriate choice when an AP needs to focus on detecting and monitoring wireless threats instead of serving clients.

Question 223: Which component provides centralized authentication for users in a typical Cisco 802.1X wireless deployment?

1. DHCP server
2. RADIUS server
3. DNS server
4. NTP server

Correct Answer: 2. RADIUS server

Explanation:

A RADIUS server commonly performs the authentication-server role in an enterprise 802.1X wireless architecture. The wireless client acts as the supplicant, while the AP or controller performs the authenticator role and communicates with the RADIUS server. The RADIUS server validates authentication information and can return authorization attributes based on policy. DHCP provides IP configuration, DNS provides name resolution, and NTP provides time synchronization. Therefore, the RADIUS server is the component responsible for centralized authentication in a typical enterprise 802.1X WLAN.

Question 224: Which Cisco wireless feature allows an administrator to define radio parameters such as channel width and transmit-power ranges for a group of APs?

1. RF Profile
2. AP Group
3. Mobility Anchor
4. WLAN Profile

Correct Answer: 1. RF Profile

Explanation:

An RF Profile allows administrators to define radio configuration parameters for groups of access points operating in a particular RF environment. Depending on the platform and configuration, an RF Profile can influence settings such as channel width, transmit-power ranges, data rates, and other radio-related behavior. An AP Group controls WLAN availability for selected APs, while a Mobility Anchor supports mobility traffic and a WLAN Profile defines WLAN-specific configuration. Therefore, RF Profile is the appropriate component for applying consistent radio parameters to a group of access points.

Question 225: What is the primary purpose of RRM in a Cisco wireless network?

1. To provide DNS resolution
2. To authenticate wireless users
3. To automatically optimize radio-channel and transmit-power settings
4. To provide DHCP leases

Correct Answer: 3. To automatically optimize radio-channel and transmit-power settings

Explanation:

Radio Resource Management (RRM) helps Cisco wireless infrastructure dynamically manage RF resources. It can evaluate information from access points and make adjustments to parameters such as channel assignment and transmit power in response to changing RF conditions. This can help maintain coverage, reduce interference, and improve overall wireless performance. RRM does not provide DNS, DHCP, or user authentication services. Those functions belong to other network components. Therefore, automatically optimizing radio channels and transmit-power settings is the primary purpose of RRM in a Cisco wireless environment.

Question 226: Which WLAN security method requires individual user authentication through an authentication server rather than a shared pre-shared key?

1. WPA2-Personal
2. WPA3-Personal
3. Open Authentication
4. WPA2-Enterprise

Correct Answer: 4. WPA2-Enterprise

Explanation:

WPA2-Enterprise uses 802.1X authentication and an authentication server such as RADIUS to provide individual authentication for wireless users or devices. This differs from WPA2-Personal, which uses a shared pre-shared key. WPA3-Personal uses SAE for password-based authentication, while Open Authentication does not provide equivalent enterprise authentication. WPA2-Enterprise therefore allows administrators to apply centralized authentication and authorization policies rather than relying on one shared WLAN password for all users.

Question 227: Which CAPWAP channel is primarily responsible for carrying management and control information between an AP and its controller?

1. CAPWAP control channel
2. CAPWAP data channel
3. RADIUS channel
4. DHCP channel

Correct Answer: 1. CAPWAP control channel

Explanation:

The CAPWAP control channel carries management and control information between a lightweight Cisco access point and its wireless LAN controller. This includes information required for AP management, configuration, and operational control. The CAPWAP data channel is used to transport client data traffic in centralized forwarding deployments. RADIUS is used for AAA communication, while DHCP provides IP configuration. Therefore, the CAPWAP control channel is the mechanism responsible for AP-to-controller management and control communication.

Question 228: A wireless client has strong RSSI but poor application performance. Which additional metric should be examined to determine whether RF noise is affecting the connection?

1. SSID length
2. SNR
3. DHCP lease duration
4. VLAN name

Correct Answer: 2. SNR

Explanation:

Signal-to-Noise Ratio (SNR) provides important context for interpreting received signal strength. A client can have strong RSSI while still experiencing poor performance if the noise floor is also high. Examining SNR helps determine how clearly the desired signal stands above the surrounding RF noise. Other factors such as channel utilization and retransmissions should also be considered during a complete troubleshooting process. SSID length, DHCP lease duration, and VLAN naming do not measure RF signal quality. Therefore, SNR is an important additional metric when strong RSSI does not correspond to expected application performance.

Question 229: Which IEEE 802.11 amendment introduced Fast BSS Transition to reduce roaming interruption?

1. 802.11k
2. 802.11v
3. 802.11r
4. 802.11w

Correct Answer: 3. 802.11r

Explanation:

IEEE 802.11r introduced Fast BSS Transition (FT), which is designed to reduce the time required for a wireless client to transition between access points within a supported mobility domain. Traditional roaming can involve authentication and key-establishment operations that introduce additional delay. 802.11r provides mechanisms that allow security context to be established more efficiently during supported roaming scenarios. 802.11k focuses on neighbor and radio measurements, 802.11v provides network-assisted transition capabilities, and 802.11w protects management frames. Therefore, 802.11r is the amendment associated with Fast BSS Transition.

Question 230: Which feature allows a wireless client to receive information about neighboring APs and their radio characteristics before roaming?

1. 802.11k
2. 802.11r
3. 802.11w
4. 802.11ax TWT

Correct Answer: 1. 802.11k

Explanation:

IEEE 802.11k provides radio resource measurement capabilities, including Neighbor Reports that can give clients information about nearby access points and their radio characteristics. This information can help clients make more informed roaming decisions and reduce the need for extensive scanning across multiple channels. 802.11r is focused on fast transition authentication, 802.11w provides management-frame protection, and TWT is a Wi-Fi 6 power-management feature. Therefore, 802.11k is the technology most directly associated with providing neighboring AP information to roaming clients.

Question 231: Which technology helps a wireless network prioritize voice and video traffic over ordinary best-effort traffic?

1. DHCP Option 43
2. WMM
3. CAPWAP Discovery
4. CleanAir

Correct Answer: 2. WMM

Explanation:

Wi-Fi Multimedia (WMM) provides traffic prioritization through four access categories: voice, video, best effort, and background. This allows delay-sensitive traffic such as voice and video to receive preferential access to the wireless medium. WMM is based on enhanced distributed channel access mechanisms that provide different contention parameters for each category. DHCP Option 43 assists with AP controller discovery, CAPWAP Discovery locates controllers, and CleanAir provides RF interference intelligence. Therefore, WMM is the technology used to prioritize voice and video traffic over lower-priority traffic.

Question 232: Which WMM access category is normally associated with video traffic?

1. AC_BK
2. AC_BE
3. AC_VO
4. AC_VI

Correct Answer: 4. AC_VI

Explanation:

WMM classifies wireless traffic into four access categories. AC_VO is intended for voice, AC_VI for video, AC_BE for best-effort traffic, and AC_BK for background traffic. Video applications can require relatively low delay and sufficient bandwidth, so WMM provides a higher-priority category for this type of traffic. The exact behavior also depends on how applications and network devices classify packets. Therefore, AC_VI is the WMM access category specifically associated with video traffic.

Question 233: Which wireless security feature provides protection against forged deauthentication and disassociation frames?

1. PMF
2. OFDMA
3. TWT
4. MU-MIMO

Correct Answer: 1. PMF

Explanation:

Protected Management Frames (PMF), defined by IEEE 802.11w and incorporated into newer Wi-Fi security standards, provides protection for supported management frames. This can help prevent attackers from using forged deauthentication or disassociation frames to disrupt wireless clients. OFDMA improves spectrum efficiency, TWT coordinates scheduled client activity, and MU-MIMO enables simultaneous communication with multiple clients using spatial streams. Therefore, PMF is the security feature directly associated with protecting supported management frames against spoofing and disruption attacks.

Question 234: Which condition is most likely to increase co-channel contention in a high-density wireless deployment?

1. Smaller coverage cells with carefully reused channels
2. Lower client density
3. Excessively large coverage cells caused by high transmit power
4. Appropriate channel planning

Correct Answer: 3. Excessively large coverage cells caused by high transmit power

Explanation:

Excessively large coverage cells can increase co-channel contention because more access points and clients may share the same RF channel across overlapping areas. High transmit power can enlarge cell boundaries and cause distant devices to detect and defer to transmissions that might otherwise be outside their effective coverage area. High-density designs generally require careful channel reuse, appropriate transmit-power levels, and suitable cell sizing. Lower client density and well-planned channel reuse can reduce contention. Therefore, excessively large coverage cells caused by high transmit power can contribute significantly to co-channel contention.

Question 235: Which Cisco feature can provide centralized visibility into wireless client connectivity and health information?

1. Wireless Assurance
2. DHCP Proxy
3. RADIUS Accounting
4. CAPWAP Data Channel

Correct Answer: 1. Wireless Assurance

Explanation:

Wireless Assurance provides centralized analytics and visibility into wireless infrastructure and client health. It can collect and analyze operational information to help administrators investigate connectivity problems, RF conditions, performance issues, and client experience. DHCP Proxy assists with DHCP communication, RADIUS Accounting records AAA session information, and the CAPWAP data channel transports client traffic in centralized architectures. Wireless Assurance is therefore the capability most directly associated with centralized monitoring and analytics of wireless client connectivity and infrastructure health.

Question 236: Which RF measurement represents the amount of unwanted RF energy present in the environment?

1. EIRP
2. RSSI
3. Noise floor
4. Channel width

Correct Answer: 3. Noise floor

Explanation:

The noise floor represents the level of unwanted RF energy present in the wireless environment. It can come from thermal noise, electronic equipment, neighboring transmitters, and other RF sources. A high noise floor reduces the effective signal-to-noise ratio and can negatively affect wireless reliability and performance. RSSI measures received signal strength, EIRP describes effective radiated power, and channel width identifies the spectrum occupied by a transmission. Therefore, noise floor is the RF measurement that directly represents unwanted background RF energy.

Question 237: Which factor should be considered when calculating the effective radiated power of a wireless AP?

1. Antenna gain and cable losses
2. SSID name length
3. DHCP lease duration
4. RADIUS accounting interval

Correct Answer: 1. Antenna gain and cable losses

Explanation:

Effective Isotropic Radiated Power (EIRP) depends on the transmitter output power, antenna gain, and losses in the RF path. Cable and connector losses reduce the effective power reaching the antenna, while antenna gain increases the effective radiated power in the antenna’s direction of gain. Accurate EIRP calculations are important for RF planning and regulatory compliance. SSID naming, DHCP lease duration, and RADIUS accounting intervals do not determine EIRP. Therefore, antenna gain and cable losses are important factors when determining effective radiated power.

Question 238: Which wireless design approach is most appropriate when many clients must be supported in a high-density area?

1. Use maximum transmit power on every AP
2. Use wider channels everywhere
3. Focus on capacity, airtime utilization, channel reuse, and appropriate cell sizing
4. Deploy only one AP with maximum power

Correct Answer: 3. Focus on capacity, airtime utilization, channel reuse, and appropriate cell sizing

Explanation:

High-density wireless design should prioritize available airtime and capacity rather than simply maximizing coverage. Appropriate cell sizes, channel reuse, channel widths, transmit power, and AP placement all influence how efficiently clients share the wireless medium. Excessive transmit power can create unnecessarily large cells, while very wide channels can reduce the number of channels available for reuse. A single high-power AP is also unlikely to provide sufficient capacity for many simultaneous clients. Therefore, capacity planning, airtime utilization, channel reuse, and appropriate cell sizing are central considerations in high-density WLAN design.

Question 239: Which Cisco wireless technology can detect and classify interference from devices such as microwave ovens or Bluetooth equipment?

1. CleanAir
2. RADIUS
3. DHCP Proxy
4. 802.1X

Correct Answer: 1. CleanAir

Explanation:

Cisco CleanAir provides spectrum intelligence that can detect and classify various sources of RF interference, including non-Wi-Fi devices that operate in wireless frequency bands. Identifying the type and impact of interference can help administrators determine whether an environmental RF source is contributing to connectivity or performance problems. RADIUS and 802.1X are associated with authentication, while DHCP Proxy assists with IP address assignment processes. Therefore, CleanAir is the Cisco wireless technology most directly associated with detecting and classifying non-Wi-Fi interference sources.

Question 240: Which statement best describes the purpose of a wireless site survey before deploying access points?

1. It determines only the SSID names to be used
2. It evaluates RF coverage, interference, capacity requirements, and AP placement
3. It replaces the need for WLAN security configuration
4. It automatically creates all RADIUS accounts

Correct Answer: 2. It evaluates RF coverage, interference, capacity requirements, and AP placement

Explanation:

A wireless site survey is used to understand the physical and RF environment before or during WLAN deployment. It can help determine appropriate AP placement, expected coverage, channel reuse, interference conditions, capacity requirements, and other RF design considerations. A survey does not replace WLAN security configuration or automatically create authentication accounts. SSID naming is only a small configuration detail and is not the primary purpose of a site survey. Therefore, evaluating RF coverage, interference, capacity requirements, and access-point placement accurately describes the purpose of a wireless site survey.
