A high-density wireless network is designed. Which Cisco WLC configuration setting must be incorporated in the design to encourage clients to use the 5 GHz spectrum?

A. Band Select

B. RRM

C. Cisco Centralized Key Management

D. load balancing

An engineer must ensure that the wireless network can accomplish fast secure roaming by way of caching keys on the access points. Which key caching mechanism is enabled by default on a Cisco AireOS WLC?

A. SKC

B. OKC

C. 802.11r

D. CCKM

A wireless deployment in a high-density environment is being used by vendors to process credit card payment transactions via handheld mobile scanners. The scanners are having problems roaming between access points in the environment. Which feature on the wireless controller should have been incorporated in the design?

A. RX SOP

B. 802.11w

C. AP Heartbeat Timeout

D. Application Visibility Control

An engineer as performing a Layer 1 passive wireless site survey utilizing a channel analyzer software in the 2.4 GHz spectrum. Which chart indicates the ratio of interference present during the duration of the capture?

A. Option A

B. Option B

C. Option C

How does AP failover priority for access points function when configured with priority 1 or 4?

A. When configured with priority 1, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.

B. When configured with priority 4, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.

C. When configured with priority 4, the access point is assigned with the lowest priority level and it is marked as low. This access point fails over after other access points with the higher priority when there is primary controller failure.

D. When configured with priority 1, the access point is assigned with the medium priority level and it is marked as medium. This access point fails over after other access points with the higher priority when there is primary controller failure.

An AP is receiving 802.11 packets on its 802.11a radio with an RSSI value of -77 dBm. The current AP is part of an AP group that has been assigned an RF profile with RX-SOP set to Medium for 802.11a. Which action does the AP take with the packets?

A. All frames are classified as non-Wi-Fi frames and are not decoded by the 5 GHz radio.

B. Frames are decoded by the 2.4 GHz radio.

C. All frames are classified as non-Wi-Fi frames and are not decoded by the 2.4 GHz radio.

D. Frames are decoded by the 5 GHz radio.

While performing an AP-on-a-stick survey with a cell boundary of -67 dBm, an engineer is consistently reading SNR less than 15 dB in a particular area within the cell boundary. What is causing this issue?

A. Another signal is interfering with the AP.

B. The engineer forgot to compensate for the wall type in that area.

C. The AP transmit power is too low.

D. The engineer is too far from the AP.

A wireless engineer must assess constraints for a future WLAN deployment for a site that consists of office cubicles. Which signal propagation attenuation result is associated with this environment?

A. reflection

B. absorption

C. noise

D. refraction

An engineer must create a multicampus architecture wireless design to accommodate 4500 access points for wireless data and guest access. Which model controller fits the requirements to support all access points on one high availability controller setup?

A. 3504

B. 5508

C. 5520

D. 8540

A customer has this wireless design: two Cisco Catalyst 9800 Series wireless controllers that are configured in a high-availability SSO cluster to manage the APs in a local office network 100 APs in local mode that are registered to the high-availability cluster one Catalyst 9800 Series wireless controller that is deployed as an anchor in a DMZ a CAPWAP tunnel in UP state between the high-availability cluster and the anchor WLC

The customer wants the anchored traffic to remain up if a single WLC in the high-availability cluster fails. How must this requirement be incorporated into the design?

A. Configure the APs with the high-availability cluster as the primary base.

B. Deploy EMC APs as anchors and configure a high-availability cluster.

C. Create a separate EoIP tunnel for each WLC in the high-availability cluster.

D. Configure the mobility MAC address for the high-availability cluster.
