A customer has a central Cisco WLC that manages APs in FlexConnect mode. The wireless infrastructure supports multiple small branches. One branch deploys new CCX wireless phones that are authenticated by a central Cisco ISE via PEAP/IMSCHAPv2, and traffic is switched locally. The customer must reduce the number of full authentication requests and optimize roaming for the new phones. Which action accomplishes the requirement?

An engineer designed a new wireless network for an enterprise customer. The customer is concerned that some wireless features may not be available because the bill of materials has only Base and no WPlus licenses for the Cisco WLC version 8. What is the reason for the engineer to take this approach regarding the licenses?

An architect configures a set of AirOS controllers to be in the same mobility group as the existing controllers. The implementation should facilitate inter-controller roaming for users in their new campus. After the configuration, the mobility tunnel is not operational for the data path in the network. Which two validations should be performed? (Choose two.)

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?

An engineer must produce a passive survey report. The coverage heat map shows the entire site with all signal levels. To see only the desired coverage, which action must the engineer take?

An engineer is performing an AP-on-a-stick survey and finds that the 5 GHz channel overlap is too high when an appropriate number of APs are used for the density requirements. Which two actions during the survey reduce channel overlap? (Choose two.)

An engineer is designing a new wireless network. Based on the design, OfficeExtend AP functionality must be used. Which type of license must the Cisco 5520 WLC v8.3 have?

A Cisco controller-based wireless network must support workgroup bridges. The APs configured as workgroup bridges must support wired and wireless clients. The wireless clients must connect to the spare radio. What is the maximum number of wired client connections supported on a workgroup bridge?

A customer has a Cisco wireless network that supports VoWLAN services. The customer wants supported voice clients to receive roaming recommendations and suggestions from APs. This functionality must not impact non-VoWLAN clients. What should be enabled on the VoWLAN SSID?

An engineer is implementing a wireless design for a service provider. The design includes a Catalyst 9800, a stack of two Catalyst 9300X-48HX switches, and 9166 APs. Each AP must be named using the Floor-439412509-01X sting where X is the area number. The engineer wants to connect the APs to the switch stack using POE. How many APs must the engineer connect to the stack so the APs run using full functionalities?

An engineer is performing an active survey of a network that must support different types of mobile devices. The devices must be able to run an application that requires a minimum RF of 73 dBm. Which mobile device must be used for the survey?

A customer deploys a new Cisco high-density wireless network within the open areas of a mall to provide free public wireless on 5 GHz. The existing mall tenants have their own wireless networks that are independently managed. Which design approach minimizes channel utilization for the public network?

An engineer must assess an existing company WLAN to determine the possibility for future IEEE 802.11ac Wave 2 wireless deployment. The existing WLAN is IEEE 802.11a/n and has IEEE 802.11n and 802. 11a clients. The engineer must advise the customer about support for these older clients on the new APs. What happens with client compatibility?

An engineer designs a new wireless network that uses a Cisco Catalyst 9800 Series wireless controller. The controller must be in a DMZ. The internal network is to be at the main on-premises data center of the customer. In addition, the customer wants to establish an EoIP tunnel to a Cisco 5520 WLC that is in a regional office. How must this requirement be incorporated into the design?

A network consultant must create a wireless design with these characteristics:
• Provide coverage in a single contiguous space.
• Support dual-band wireless coverage.
• Use nine APs for full coverage in a 5 GHz band.

What must the engineer do to mitigate co-channel interference and maintain coverage in 2.4 GHz?

A wireless consultant reviewing the installation of an old wireless network. The existing AireOS controllers are running software version 6.0.4539:44024. The customer is using OEAP and wants to keep this functionality. Which licenses should the consultant propose with the latest controller software version?

A university lecture hall has a Cisco wireless high-density network with this configuration:
• 5 GHz only
• 20-MHz channels
• UNII-1, UNII-2, and UNII2-E channels
• TPC minimum = 8
• TPC maximum = 14

The lecture hall is 200 feet by 100 feet and has 16 Cisco APs that use directional antennas. Which feature must be included in the design to mitigate and reduce high-channel utilization from rogue APs?

An engineer must optimize client roaming after noticing that clients in the environment are not roaming as expected. Upon reviewing an over-the-air packet capture, the engineer sees that the AP is sending a BSS Transition Management query to the client, which causes it to roam. The disassociation imminent feature is not enabled on the WLAN. What is the cause of the issue?

A customer has a centralized wireless deployment with N+1 high availability and few open authentication SSIDs configured. After failover, all APs are broadcasting all SSIDs, but the clients are assigned IP addresses from a different subnet. The WLANs on both WLCs are configured with the same dynamic interfaces. Which feature must be incorporated in the wireless design of the second controller?

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 wireless network consists of:
• two IOS XE controllers installed in a data center
• 9100 series APs
• corporate and a guest WLAN

The customer must high availability pair two Cisco WLCs for the client SSO. Which two design approaches must the engineer take to meet the requirement? (Choose two.)
