질문 # 32
An engineer is designing a WLAN to support wireless VoIP handsets in an enterprise campus.
Which set of RF design targets must be met at the cell edge?
정답：C
설명：
Cisco's validated design targets for voice over WLAN require a stronger and cleaner signal than data-only deployments because voice is delay- and loss-sensitive and cannot tolerate retransmissions. The cell edge RSSI target is -67 dBm, which ensures the handset can sustain a high enough data rate to keep airtime consumption low. The SNR target is 25 dB, which provides sufficient margin above the noise floor for reliable demodulation without excessive retries. Cell overlap of 20% ensures the handset can find and associate to the next AP before the current signal degrades, allowing roams to complete without dropped audio. Data-only designs typically use -72 dBm and 20 dB SNR with 15% to 20% overlap, which is insufficient for voice. Overly aggressive targets such as -62 dBm with 35% overlap create unnecessary co-channel interference and increase cost.
질문 # 33
During a site survey for a new wireless deployment in a multifloor office building, an engineer must identify sources of interference and ensure optimal AP placement for 5 GHz coverage.
While walking the site with a spectrum analyzer, the engineer notices periodic spikes in the noise floor on several channels and inconsistent signal strengths reported by the survey tool, despite visually unobstructed paths. Which action must the engineer take next to accurately assess and mitigate the Layer 1 interference?
정답：C
설명：
Layer 1 interference analysis is foundational to the Cisco site survey methodology. When a spectrum analyzer reveals periodic noise floor spikes across multiple channels with no clear line- of-sight obstruction, the root cause is almost certainly a non-802.11 device -- candidates include cordless phones, video cameras, microwave equipment, or radar systems triggering DFS events.
The correct engineering response is systematic documentation: capture the time of occurrence, the specific frequency or frequency range, and the geographic location of the interference signature. This triangulation data enables correlation with physical devices present in the facility.
질문 # 34
An engineer must design and configure a wireless network for pervasive coverage in an oil terminal, casual web and email traffic, 5 GHz. What is the best design?
정답：D
설명：
An oil terminal presents specific wireless design constraints: the requirement is pervasive coverage (maximum geographic coverage) for low-bandwidth applications (casual web and email). These requirements prioritize coverage reach over throughput optimization. The correct approach is to keep all data rates enabled, including lower rates such as 6, 9, 12, and 18 Mbps -- because in an industrial environment with challenging RF propagation paths, reflective surfaces, and potential obstructions, lower data rates extend the functional coverage range of each AP.
Web and email traffic does not require high data rates; even 1-6 Mbps is sufficient for these applications. Disabling rates below 54 Mbps (Option A) would dramatically shrink each AP's effective coverage area, requiring many more APs for pervasive coverage and failing the primary design objective. Assigning static maximum power without RRM auto-adjustment creates excessive co-channel interference.
질문 # 35
The wireless team must configure a new voice SSID for optimized roaming across multiple WLCs with Cisco 8821 phones. Which two settings accomplish this goal? (Choose two.)
정답：A,C
설명：
For optimized roaming across multiple Wireless LAN Controllers (WLCs) with Cisco 8821 IP phones, two critical settings must be configured. First, configuring mobility groups between WLCs (Option A) allows for seamless inter-controller roaming by establishing mobility tunnels between controllers, enabling them to share client security context, preventing re-authentication when a phone roams from an AP on one WLC to an AP on another. Second, using Cisco Centralized Key Management (CCKM) for authentication (Option B) reduces the time required for re- authentication during roaming from a full 802.1X exchange to a single-message re-key process.
CCKM stores the wireless security keys at the WLC level, enabling rapid key re-derivation during roaming without contacting the RADIUS server.
질문 # 36
A customer has a Cisco wireless network that supports VoWLAN services. The customer wants supported voice clients to receive roaming recommendations and suggestions from APs. This functionality must not impact non-VoWLAN clients. What should be enabled on the VoWLAN SSID?
정답：A
설명：
IEEE 802.11v BSS Transition Management is the standard that enables the network (via the AP) to actively provide roaming recommendations and suggestions to associated clients. When enabled on a SSID, the AP can send BSS Transition Management Request frames to clients, informing them of preferred target APs ranked by signal quality, load, and channel conditions.
Critically, BSS Transition Management is a voluntary mechanism -- clients that support 802.11v can act on the AP's recommendation, while clients that do not support 802.11v simply ignore the BSS Transition Request frames and continue operating normally. This selective applicability directly satisfies the requirement that non-VoWLAN clients must not be impacted.
