Cisco Designing Cisco Wireless Networks 認定 300-110 試験問題 (Q28-Q33):

質問 # 28
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?

A. Set the XOR radio role to Sniffer mode and the slot 1 radio to Client Serving on all the APs.
B. Set the XOR radio role to Client Serving and the slot 1 radio to Sniffer mode on all the APs.
C. Set the XOR radio role to Client Serving and the slot 1 radio to Monitor mode on all the APs.
D. Set the XOR radio role to Monitor mode and the slot 1 radio to Client Serving on all the APs.

正解：D

解説：
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 - it must remain in Client Serving mode to maintain uninterrupted 5 GHz WLAN service. The XOR radio (slot 0), currently either idle or operating as a secondary 5 GHz radio, can be repurposed without impacting client service. Setting the XOR radio to Monitor mode enables it to continuously scan all channels across both the 2.4 GHz and 5 GHz spectrum for rogue AP detection, using the embedded CleanAir and WIDS capabilities. In Monitor mode, the XOR radio operates full-time as a dedicated scanner, providing rogue detection coverage on 2.4 GHz (previously uncovered since all services were 5 GHz) and supplementary scanning on 5 GHz. This eliminates the need for additional dedicated monitor mode APs. Options A, C, and D either place the slot 1 radio in a non-client-serving role (disrupting existing connectivity) or use the inappropriate Sniffer mode instead of Monitor mode for rogue detection.

質問 # 29
An engineer is designing the wired infrastructure to support VoWLAN. Which QoS design should be applied to the switch ports connecting the APs?

A. Configure the AP switch port as an untrusted port with a policer at 1 Mbps.
B. Trust CoS on the AP switch port and mark all traffic to DSCP 0.
C. Apply a default queueing policy without any trust configuration.
D. Trust DSCP on the AP switch port so that the CAPWAP outer header marking is preserved.

正解：D

解説：
In a centrally switched CAPWAP deployment, client traffic is encapsulated between the AP and the controller, and the AP copies the QoS marking from the inner client packet into the DSCP field of the outer CAPWAP header. If the switch port connecting the AP does not trust DSCP, the switch rewrites those markings to zero at ingress and every voice packet loses its priority treatment for the remainder of its journey across the wired network. Trusting DSCP on the AP- facing port preserves the marking end to end and allows the campus queueing policies to place voice into the priority queue. Trusting CoS is ineffective here because the AP-to-switch link is typically an access port carrying untagged frames with no 802.1p field to trust. Leaving the port untrusted or policing it aggressively strips or drops the very traffic the design is intended to protect, and omitting trust configuration on a switch that defaults to untrusted produces the same failure.

質問 # 30
A customer has two Cisco 5520 WLCs that manage all APs throughout the network. The WLCs are in different locations to provide geographical redundancy. A mobility group has been configured on both WLCs and has an UP status on both controllers. The APs in location A are statically configured to use controller A as the primary and controller B as the secondary. If the WLC in location A goes offline, the APs successfully join the WLC in location B, but they do not fail over to their primary configured controller when it recovers.
Which configuration task fixes the issue?

A. Enable AP fallback globally on the WLC.
B. Configure the WLC in location A as primary using the CAPWAP AP Controller IP Address command on all the location A access points.
C. Change the AP Failover Priority to critical.
D. Use DHCP Option 43 and specify WLC in location A as primary.

正解：A

解説：
Enabling AP fallback globally on the WLC allows access points to reconnect to their primary controller after they have connected to a secondary controller due to the primary being offline. This is the exact behavior described in the scenario - APs successfully fail over to the secondary WLC but do not return to the primary WLC when it recovers. AP Fallback is a WLC-level setting that monitors the availability of each AP ' s configured primary controller and initiates a reconnection when the primary becomes reachable again.
Without AP Fallback enabled, APs remain on whatever controller they most recently joined - in this case, the secondary - even after the primary recovers. The CAPWAP AP Controller IP Address command (Option A) permanently changes the primary controller configuration on the AP, which is not the intended solution - the AP already has the correct primary configured. DHCP Option 43 (Option B) is used for initial AP discovery, not fallback. AP Failover Priority (Option D) controls which APs are processed first during a failover event, not whether APs return to their primary controller.

質問 # 31
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.)

A. Configure AVC profile on new SSID.
B. Use AVC to tag traffic voice traffic as best effort.
C. Configure AP groups between WLCs.
D. Use Cisco Centralized Key Management for authentication.
E. Configure mobility groups between WLCs.

正解：D、E

解説：
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.

質問 # 32
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?

A. Document the affected channels and locations, then attempt to adjust the channel plan to avoid the frequencies that experience the most interference during initial deployment.
B. Use the wireless controller monitoring tools in combination with the site survey tool heatmap output to determine AP locations and capture the Layer 1 spectrum analysis for ongoing analysis.
C. Increase the transmit power of all APs to compensate for the signal fluctuations and re-run the survey to verify the visual line-of-sight and signal strength measurements.
D. Use the spectrum analyzer to document the time, frequency, and location of the noise spikes, then correlate them with possible non-Wi-Fi interferers and adjust AP placement accordingly.

正解：D

解説：
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. Simply increasing transmit power (Option A) raises the noise floor for neighboring cells and worsens co-channel interference. Using WLC monitoring tools (Option B) is insufficient because the WLC cannot detect non-802.11 energy at Layer 1. Adjusting the channel plan (Option C) without fully characterizing the interferer is premature. Only Option D follows the correct Cisco survey methodology for Layer 1 analysis, leading to actionable AP placement adjustments.
