質問 1

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）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.

（C）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.

（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.

質問 3

A customer has a single anchor WLC named Anchor A.
Anchor A is in a DMZ and provides guest access. The customer wants to deploy an additional anchor controller named Anchor B to provide redundancy if Anchor A fails. Which design approach should be taken for the guest WLAN priority on the foreign WLC for each anchor WLC?

（A）Set Anchor A to priority 1 and Anchor B to priority 1.

（B）Set Anchor A to priority 1 and Anchor B to priority 3.

（C）Set Anchor A to priority 3 and Anchor B to priority 1.

（D）Set Anchor A to priority 3 and Anchor B to priority 3.

質問 4

An engineer is finalizing the design for a WLAN dedicated to wireless VoIP handsets. Which setting should be applied to this WLAN, and why?

（A）Disable Band Select because the probe suppression it uses can delay roaming.

（B）Enable Band Select to push handsets to 5 GHz and reduce 2.4 GHz congestion.

（C）Enable Passive Client mode for the handset VLAN.

（D）Enable Client Load Balancing to distribute handsets evenly across APs.

質問 5

A consultant must design a WLAN for a large campus with high AP density, 50-100 clients per cell, 5 Mbps throughput per client minimum, 5 GHz and 2.4 GHz coverage at -67 dBm, and no
802.11b clients. Which two WLAN design approaches meet the requirements? (Choose two.)

（A）Enable 802.11b data rates.

（B）Set the 5 GHz channel widths to 80-160 MHz.

（C）Set the minimum mandatory data rates to 12-18 Mbps.

（D）Configure up to six SSIDs on any AP.

（E）Reduce the 2.4 GHz coverage with FRA.

質問 6

A consulting engineer for a copper mine is trying to extend the network connectivity of autonomous trucks via Cisco IW3702 APs. The WGB design requirements include: latency- sensitive application (truck slows at 10 sec, stops at 20 sec of connection loss), aggressive scanning and roaming, enterprise-grade security without certificates on each AP, multiple clients in different VLANs on the WGB, and channel scan parameters restricted to only channels in the truck path. Which design approach meets the requirements?

（A）WGB in static mode with EAP Fast connected to a dot1q-capable switch

（B）WGB in mobile station mode with EAP Fast connected to a dot1q-capable switch

（C）WGB in mobile station mode with EAP-TLS connected to a dot1q-capable switch

（D）WGB in static mode with EAP-TLS connected to a dot1q-capable switch

質問 7

An engineer must assess an existing company WLAN to determine the possibility for future IEEE
802.11ac Wave 2 wireless deployment. All access switches are Fast Ethernet-capable only, and the wired infrastructure between existing APs and access switches is based on the CAT 6A standard. Which two actions provide maximum support of Cisco 3800 Series access points?
(Choose two.)

（A）Ensure that cable distances between access switches and APs are not longer than 55 meters.

（B）Replace the existing switches with mGig switches.

（C）Replace the existing wiring infrastructure with the CAT-7E wiring standard.

（D）Ensure that cable distances between access switches and APs are not longer than 100 meters.

（E）Replace the existing switches with gigabit switches with 10G uplinks.

質問 9

A customer has two Cisco wireless controllers named WLC-A and WLC-B. Each controller is in a different building on a campus. The WLCs have different Layer 3 interfaces and broadcast the same SSIDs from their respective APs. Users must remain connected to the same VLAN and maintain their IP addresses during roaming from the APs attached to WLC-A and WLC-B. Which action accomplishes the requirement?

（A）Enable 802.11r on each SSID on both WLCs to allow caching of the PMK.

（B）Create a mobility group between the two WLCs to allow auto-anchoring.

（C）Enable AP groups using the same name on both WLCs for each group.

（D）Create an SSO cluster to ensure that client sessions sync between WLCs.
