A network engineer must design a new wireless solution for a company, but the budget can only stretch to include a single Cisco 9800-40 WLC. The company requires high availability between the WLC and the core switch in the event of a cable failure. The WLC must dynamically manage port redundancy and perform load balancing between APs transparently. Which design approach must the engineer take to meet the requirements?

A. LAG

B. Multi-LAG

C. LACP

D. PAgP

A customer is migrating from a legacy Cisco AireOS WLC to a new Cisco 9800 IOS XE WLC with Cisco 9100 APs.

The new Catalyst 9800 WLC deployment is configured to use SSO. Which command must be added to meet the requirements?

A. C9800# chassis redundancy ha-interface local-ip < local IP > subnet < local IP subnet > remoteip < remote >

B. C9800(config)# ip default-gateway < IP >

C. C9800# wireless mobility mac-address < MAC >

D. C9800(config)# management gateway-failover enable

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 Ethernetcapable 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. Replace the existing switches with mGig switches.

B. Replace the existing switches with gigabit switches with 10G uplinks.

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

D. Replace the existing wiring infrastructure with the CAT-7E wiring standard.

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

A university has three campus locations and the main data center. Each campus location has a Cisco Catalyst 9800-40 WLC that manages 600 APs. The data center has a Catalyst 9800-40 WLC, which serves as N+1 backup for each campus WLC. A consulting engineer must install four additional Catalyst 9800-40 WLCs to serve as high availability SSO pairs for each campus, but only two have been approved due to budget restrictions. Requirements: Data center WLC must always be available as N+1 backup, Campus1 WLC must operate with zero downtime, and in the event of multiple campus outages, the AP priority order is to support Campus3, Campus2, then Campus1. Which design approach must the consulting engineer take?

A. The data center WLC and Campus3 WLC are the high availability SSO pair. Campus1 APs have priority 4, Campus2 APs have priority 2, and Campus3 APs have priority 1.

B. The data center WLC and Campus1 WLC are the high availability SSO pair. Campus1 APs have priority 4, Campus2 APs have priority 2, and Campus3 APs have priority 1.

C. The data center WLC and Campus1 WLC are the high availability SSO pair. Campus3 APs have priority 4, Campus2 APs have priority 2, and Campus1 APs have priority 1.

D. The data center WLC and Campus3 WLC are the high availability SSO pair. Campus3 APs have priority 4, Campus2 APs have priority 2, and Campus1 APs have priority 1.

An engineer is designing a solution where guests terminate on an anchor controller in the DMZ. The engineer is having issues and wants to test connectivity between members of a mobility group. Which two steps must be performed to test whether a mobility control packet can be reached over the management interface? (Choose two.)

A. Use the mping command on both WLCs.

B. Use the eping command on both WLCs.

C. Open UDP port 16666 between both WLCs.

D. Open IP protocol 97 between both WLCs.

E. Use the tracert command on the WLC.

An engineer is designing a wireless network in a historic building that has large rooms and ornate wall coverings. Which approach must be considered first when placing access points?

A. aesthetics

B. RF coverage

C. cell overlap

D. RF interference

A community bank has three campus locations and one HQ with the data center. Each campus has four Cisco Catalyst 9120 APs. Poor WAN uplinks cause impacted connectivity back to HQ, and each campus is planned to have its own EWC controller based on C9120 AP to keep traffic local. Guest WLAN will be routed locally. Employee WLAN must be authenticated 802.1x PEAP via HQ ISE but can pass traffic locally once authenticated. HQ WLC will be the primary backup WLC for each WLC. Which design approach should the consulting engineer take?

A. One C9120 AP in each campus must be converted to EWC mode, and the preferred controller is set to that AP with HQ WLC set as N+1 backup. The campus guest WLAN will use local web auth on guest VLAN, and employee WLAN will need the HQ AAA server to be added to EWC.

B. Two C9120 campus APs must be converted to EWC mode, one for the active controller and the other for standby set as N+1 backup. The campus guest WLAN will use local web auth on guest VLAN, and employee WLAN will need the HQ AAA server added to EWC.

C. Two C9120 campus APs must be converted to EWC mode, one for the active controller and the other for standby with HQ WLC as N+1 backup. The campus guest WLAN will use the guest anchor to HQ WLC for guest VLAN access, and employee WLAN will need the HQ AAA server added to EWC.

D. One C9120 campus AP must be converted to EWC mode, and the preferred controller is set to that AP with HQ WLC paired as mobility peer and configured as N+1 backup. The campus guest WLAN will use local web auth on guest VLAN. The campus employee WLAN will need the guest anchor back to the HQ employee WLAN.

A network engineer is designing a new wireless network. The network must include these requirements: • optimized performance • avoid interference • availability in high-density areas • roaming Which two approaches must be taken? (Choose two.)

A. 5 GHz frequency band with 20 MHz channels

B. 2.4 GHz frequency band with 20 MHz channels

C. 5 GHz frequency band with 80 MHz channels

D. 2.4 GHz frequency band with 40 MHz channels

E. 5 GHz frequency band with 40 MHz channels

An engineer must configure the virtual IP address on multiple controllers in a mobility group. Which rule must the engineer follow to ensure proper roaming?

A. Ensure that the DNS entry is tied to the virtual IP address of the WLC.

B. Use a unique IP address for each WLC.

C. Ensure that the DNS Host Name field is defined.

D. Use the same IP address for each WLC.

A wireless engineer is using Ekahau Site Survey to validate that an existing wireless network is operating as expected. A Cisco CleanAir AP is used for Layer 1 survey by using Metageek Chanalyzer only on the current operating channel. Which operating mode is configured for the Cisco CleanAir AP?

A. Local

B. Sniffer

C. Monitor

D. SE-connect

A school deploys a Cisco wireless infrastructure in its classrooms to support a high density of mobile devices.

A. Set the channel width for 802.11b to 40 MHz and set data rates to 24 Mbps and Mandatory.

B. Set the channel width for 802.11a to 40 MHz and set data rates to 24 Mbps and Supported.

C. Set the channel width for 802.11a to 40 MHz and set data rates to 24 Mbps and Mandatory.

D. Set the channel width for 802.11b to 40 MHz and set data rates to 24 Mbps and Supported.
