A network engineer observes a spike in controller CPU overhead and overall network utilization after multicast is enabled on a controller with 500 APs. Which feature connects the issue?

A. controller IGMP snooping

B. multicast AP multicast mode

D. unicast AP multicast mode

After receiving an alert about a rogue AP, a network engineer logs into Cisco Prime Infrastructure and looks at the floor map where the AP that detected the rogue is located. The map is synchronized with a mobility services engine that determines that the rogue device is actually inside the campus. The engineer determines that the rogue is a security threat and decides to stop if from broadcasting inside the enterprise wireless network. What is the fastest way to disable the rogue?

A. Go to the location where the rogue device is indicated to be and disable the power.

B. Create an SSID similar to the rogue to disable clients from connecting to it.

C. Update the status of the rogue in Cisco Prime Infrastructure to contained.

D. Classify the rogue as malicious in Cisco Prime Infrastructure.

After looking in the logs, an engineer notices that RRM keeps changing the channels for non-IEEE 802. 11 interferers. After surveying the area, it has been decided that RRM should not change the channel. Which feature must be enabled to ignore non-802.11 interference?

A. Avoid Cisco AP Load

B. Avoid Persistent Non-WIFI Interference

C. Avoid Foreign AP Interference

D. Avoid Non-802. 11 Noise

An engineer is configuring a new wireless network for guest access. The Facebook page of the company must be viewed by the guest users before they get access to the network. A Cisco MSE is used as a wireless component. Which URL must be used in the configuration as the external redirection URL?

A. http://:8084/vistor/login.do

B. http:// 8083/visitor/login.do

C. http://:8083/fbwifi/forward

D. http://:8084/fbwifi/forward

ALLAR A network engineer must segregate all iPads on the guest WLAN to a separate VLAN.

How does the engineer accomplish this task without using Cisco ISE?

A. Enable RADIUS DHCP profiling on the WLAN.

B. Create a local policy on the WLC.

C. Use an mDNS profile for the iPad device.

D. Use 802.1x authentication to profile the devices

A network administrator managing a Cisco Catalyst 9800-80 WLC must place all iOS connected devices to the guest SSID on VLAN 101. The rest of the clients must connect on VLAN 102 to distribute load across subnets. To achieve this configuration, the administrator configures a local policy on the WLC.

Which two configurations are required? (Choose two.)

A. Allow HTTP and DHCP profiling under policy map.

B. Enable device classification on global wireless settings

C. Add local profiling policy under global security policy settings

D. Assign a policy map under global security policy settings

E. Create a service template

A network administrator just completed the basic implementation of Cisco CMX and tries to implement location tracking. The administrator is having trouble establishing connectivity between one of the WLCs through NMSP. What must be configured to establish this connectivity? (Choose two.)

A. Add permanent licenses on the Cisco CMX server.

B. Allow on the firewall port 16113 between Cisco CMX and the WLC.

C. Enable NMSP on the WLC.

D. Reboot Cisco CMX after adding the WLC for the first time.

E. Add to the WLC the MAC address and SSC key for the Cisco CMX server.

An IT administrator deploys Cisco 2802i APs in all office locations, including main campus and branch offices. The WLC that manages the APs is located at the data center on the main campus. The APs on the main campus are configured to use Local mode and the APs in the branches use FlexConnect mode. Which configuration must be applied to the APs for corporate devices on the main campus to be mapped to the local LAN switch on different VLANs according to the VLAN tag ID and WLAN?

A. Enable Central DHCP Processing.

B. Disable FlexConnect Local Auth

C. Enable FlexConnect Local Switching.

D. Disable VLAN-based Central Switching.

An engineer is in the process of implementing Fastlane on a wireless network with a Mobility Express AP installed. The network must support voice and video applications for Apple devices.

A. Bronze

B. Best Effort

C. Silver

D. Platinum

A wireless network has two RF groups where Cisco WLCs are joined. APs are associated with different controllers using the round-robin approach. Rogue containment must be deployed in all controllers, but the network must not be affected by any RRM neighbor packets sent by friendly APs. Which AP authentication protection type must be enabled?

A. AP Authentication

B. AP Wireless Protection Rules

C. AP Security

D. AP Access Control
