質問 3

An engineer is troubleshooting client issues and has found that DHCP proxy is enabled on the Cisco WLC by default. The Cisco WLC unicasts the packet to the DHCP server on the WLAN, but the DHCP server does not support the DHCP proxy. Which action fixes this issue?

（A）Ensure that the IP subnet of the WLAN is defined on the DHCP server.

（B）Disable DHCP proxy on the Cisco WLC.

（C）Ensure that the switch ports that are connected to the Cisco WLC and the DHCP server are configured as a trunk.

（D）Ensure that the DHCP clients are directly connected to the interface of the server.

質問 5

Refer to the exhibit.

You are troubleshooting an AP that fails to associate to a WLC. You view the debug output on the WLC.
Which corrective action do you take?

（A）Set the WLC to Layer 3 mode.

（B）Restrict the allowed VLANs on the trunks to only the VLANs on the WLC.

（C）Ensure that the Data- 12222 and Control-12223 UDP ports are enabled.

（D）Convert the AP to autonomous mode.

質問 6

Refer to the exhibit.

Access points are deployed in an office building and users report that the real-time communications quality of experience is poor when users walk between the elevators. The elevators are a heavy metallic obstacle, and AP 3 was installed to cover the elevator area, which AP 1 and AP 2 signal does not reach. Communications are captured for a user walking from point A to point C, and it is observed that the user's iPhone device suddenly scans all bands and then roams from AP 1 to AP 3 somewhere between points B and C.
WLAN is set to 5 GHz only, Open, default rate configuration.
Which action improves the real-time application quality of experience in this area?

（A）Enable 802.11v on the WLAN.

（B）Change WLAN security to WPA2/PSK.

（C）Move AP 2 to point B.

（D）Enable Client Band Select on the WLAN.

質問 7

Which three components are needed to identify the zone of impact for non-802.11 sources of 2.4 GHz and 5.0 GHz interference? (Choose three.)

（A）WLC

（B）RF site survey tool

（C）Wi-Fi analyzer

（D）spectrum analyzer

（E）CleanAir AP

（F）MSE

質問 8

Clients are maintaining association to access points that they were previously connected to rather than roaming to adjacent access points with higher received signal strength.
Which two actions can be taken to fix this issue? (Choose two.)

（A）Increase access point power.

（B）Add access points to the areA.

（C）Utilize Rx-SOP.

（D）Enable optimized roaming.

（E）Set DCA channel sensitivity to low.

正解：C、D 解答を投票する

質問 9

Which statement about the join process of the access point is true?
Refer to the exhibit.

（A）The AP moved from this controller to its primary controller.

（B）The AP failed to join because the MAC address of the AP was not correct on the controller.

（C）The AP successfully joined the controller.

（D）The controller rejected all discovery requests from the AP because they were not received on the management interface subnet.

（E）The time on the controller is outside of the certificates validity time interval, so the join phase failed.

正解：B 解答を投票する

質問 10

While you investigate wireless connectivity issues, a user reports that only certain devices are affected. You use a wireless protocol analyzer to capture 802.11 frames. The capture reveals several issues, so you perform an RF survey.
Which troubleshooting approach are you using?

（A）divide and conquer

（B）top-down

（C）shoot from the hip

（D）bottom-up
