질문 # 95
A customer has a Cisco wireless network with two Cisco Catalyst 9800 Series WLCs in a high availability cluster, 50 Cisco 2800I APs, and all SSIDs and services are 5 GHz only. A security mandate requires that rogue APs be scanned and identified in 2.4 GHz and 5 GHz bands without impacting existing client connectivity. How must the wireless network be reconfigured to meet the requirement without purchasing additional APs?
정답：C
설명：
The Cisco Aironet 2800 Series APs feature a dual-radio architecture with a dedicated 5 GHz radio (slot 1) and a Flexible Radio Assignment (XOR) radio (slot 0) that can operate in either 2.4 GHz or 5 GHz, or be assigned to monitor mode for scanning functions. Since all existing SSIDs and services are 5 GHz only, the slot 1 (dedicated 5 GHz) radio is responsible for all current client connectivity and must remain in Client Serving mode to maintain uninterrupted service. The XOR radio (slot 0) is currently either operating as a secondary 5 GHz radio or idle. By setting the XOR radio to Monitor mode, it becomes a dedicated scanner that continuously scans all channels across both 2.4 GHz and 5 GHz spectrum for rogue AP detection, using the embedded CleanAir and WIDS capabilities. This covers the previously unmonitored 2.4 GHz band and provides supplementary 5 GHz monitoring. No additional APs need to be purchased because the existing AP's XOR radio is repurposed.
질문 # 96
A campus has eight controllers in a single RF group. The engineer wants deterministic control over which controller performs the RRM calculations. Which design approach should be used?
정답：A
설명：
By default, controllers in an RF group elect a leader dynamically, and that election can shift to a different controller after a reboot, upgrade, or network event - which means the engineer cannot predict which platform is running the RRM algorithms or where to look for RF group history and diagnostics. Configuring a static RF group leader pins that role to a chosen controller, giving deterministic behavior for troubleshooting, capacity planning, and change control, and ensuring the leader is a platform sized appropriately for the calculation load. Sharing a mobility group name governs client roaming context exchange and does not control RF group leadership.
Disabling RRM on the other controllers would leave their APs without dynamic channel and power management rather than delegating the calculation. The default election does consider platform capability and other factors rather than simply selecting the lowest IP address, and relying on it is precisely the non-deterministic behavior the static configuration exists to eliminate.
질문 # 97
An engineer configured the optimized client roaming on Cisco WLC with an RSSI threshold of -72 dBm. Clients report frequent disconnections. What must be configured for the AP to guide the client to a better AP?
정답：D
설명：
The scenario presents a critical distinction in where Cisco WLC features are configured.
Optimized roaming on Cisco WLC is a radio-level feature that monitors connected client RSSI and, when a client's signal falls below the configured threshold (-72 dBm), triggers a disassociation to force the client to reconnect to a stronger AP. However, without a mechanism to guide the client proactively before reaching the threshold, clients that disassociate simply reconnect to whatever AP their device selects, potentially causing the reported frequent disconnections. BSS Transition Management (802.11v) is configured at the SSID level and provides the complementary mechanism: before the client reaches the RSSI threshold, the AP sends a BSS Transition Management Request pointing the client toward a specific target AP with stronger signal. The correct architecture requires: optimized roaming configured at the radio level (triggering disconnection when RSSI falls too low) combined with BSS transition enabled at the SSID level (guiding the client to a better AP before forced disconnection).
질문 # 98
An engineer must perform a predictive design for a wireless network. The customer has devices that can tolerate at most 100 ms of delay when roaming. Which design criteria must be used?
정답：B
설명：
Devices that can tolerate at most 100 ms of delay when roaming are voice devices. The 100 ms maximum roaming delay threshold is the Cisco-specified design criterion for VoWLAN implementations - it defines the maximum time a handset can tolerate being disconnected from the wireless network during a roam event before the voice call is degraded or dropped. This threshold drives specific design requirements: 15-20% cell overlap at -67 dBm, fast roaming mechanisms (802.11r, CCKM, or OKC), and AP placement along user movement paths. Location services (Option A) have flexible latency requirements. Data applications (Option B) can tolerate much higher latency - typically several hundred milliseconds. Video (Option C) streaming has buffering mechanisms that allow for higher latency tolerance than real-time voice. Only voice applications have the strict 100 ms roaming delay requirement that directly influences the predictive design criteria.

질문 # 99
A wireless engineer is using Ekahau site survey to validate that an existing wireless network is operating as expected. Which type of survey should be used to identify end-to-end network performance?
정답：B
설명：
An active ping survey is used to validate network performance by sending and receiving data packets to measure end-to-end network performance, including latency, packet loss, and throughput. Ekahau site survey tools can perform active ping surveys to test the connectivity and performance of the wireless network while the surveyor walks the floor plan, producing a geographically correlated map of network performance metrics.
This differs fundamentally from passive surveys, which only measure signal strength from beacons. A GPS- assisted survey (Option A) is used for large outdoor areas to automate location tracking. Spectrum analysis (Option B) identifies Layer 1 RF conditions but does not measure network performance. A passive survey (Option C) measures RSSI and SNR but does not test actual data connectivity or throughput. Active ping is the correct tool for validating that the network delivers the expected end-to-end service levels. Reference:
