An engineer needs a wireless design to provide redundancy for APs at remote sites that are connected to Cisco 3504 Wireless LAN

Controllers. The central Cisco 5520 Wireless LAN Controller supports 2000 APs and has 1975 access points associated to it. The engineer decides that not all APs at the remote sites must remain functional in the event of a failure. How does the engineer ensure that the most important access points at the remote sites remain online while not impacting the main site?

A.

Enable Global AP Fail over Priority, set the 1975 APs to a priority of "high", and set the 25 most important APs at the remote sites to "critical".

B.

Enable AP Fallback Mode, set the 1975 APs to a priority of "high", and set the 25 most important APs at the remote sites to "critical". C. Enable Global AP Fail over Priority, leave the 1975 APs at the default priority, and set the most important APs at the remote sites to "low".

C.

Enable AP Fallback Mode, leave the 1975 APs at the default priority, and set the most important APs at the remote sites to "high".

A community bank has three campus locations and one HO with the data center operations Each campus location has tour Cisco Catalyst 9120 APs The data center has a Catalyst 9800 WLC with eight Catalyst 9120 APs. Poor WAN uplinks cause impacted branch AP and wireless client connectivity back to HO. and each campus location is now planned to have its own EWC controller based on C9120 AP to keep traffic local. This new design must accommodate these requirements:

• Guest WLAN will be routed locally.

• Employee WLAN must be authenticated 802.1x PEAP via HO data center ISE but can pass traffic locally once authenticated.

• HO WLC will be the primary backup WLC for each WLC.

Which design approach should the consulting engineer lake?

A.

Two C9120 campus APs must be converted to EWC mode, one for the active controller and the other for standby with HQ WLC set as N»1 backup. The campus guest WLAN will use the guest anchor to HO WLC for guest VLAN access, and employee WLAN will need the HQ AAA server to be added to EWC and then use that to perform the 802.1x authentication.

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 HO AAA server added to EWC.

C.

One C9120 campus AP must be converted to EWC mode, and the preferred controller is set to that AP with HO WLC should be 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 HO employee WLAN.

D.

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

In a high-density stadium deployment, which two design considerations are most important?

A.

Use of high-gain omni antennas and 2.4 GHz channels

B.

Coverage overlap of 50% and fewer APs

C.

Sectorized directional antennas and channel reuse planning

D.

Single large AP with maximum transmit power

A customer requires that two wireless APs be installed in a reception area, in a historic building, the impact of the APs on the appearance of the reception area must be minimized. Which two AP antennas should be used? (Choose two.)

A.

AP with a Yagi antenna

B.

AP with a patch antenna

C.

AP with a monopole antenna

D.

AP with an integrated antenna

E.

AP with a dipole antenna

An enterprise network administrator is asked to set up an experimental WLAN for a collaboration project with a local service provider. The WLAN must be anchored to a WLC in the service provider data center using legacy mobility mode. After the configurations are completed on the WLCs and the firewalls in the path, the data path mobility tunnel is failing to come up. What should be performed by the administrator to debug the issue?

A.

Establish a Telnet connection from a local PC to the firewall on port 97.

B.

Use the mapping command on the WLC.

C.

Establish a Telnet connection from a local PC to the firewall on port 16666.

D.

Use the mapping command on the WLC.

A company has three Cisco WLCs that are joined as a mobility group. Mobility multicast messaging is enabled All the WLCs in the mobility group communicate via a multicast. Which configuration must be identical between the three WLCs to validate communication?

A.

multicast IP address

B.

Interface IDs

C.

service port IP address

D.

management IP address

Which band provides the best balance between range and throughput for enterprise

WLANs?

A.

2.4 GHz only

B.

5 GHz

C.

900 MHz

D.

In a warehouse deployment, why is a predictive survey often insufficient?

A.

Predictive surveys cannot account for metal racks and variable inventory

B.

Warehouses do not require Wi-Fi coverage

C.

Predictive surveys are more expensive than passive surveys

D.

Warehouses always use only 2.4 GHz Wi-Fi

An engineer is performing a predictive wireless design for a medical treatment environment, which requires data and voice services. What is the minimum requirement for the design?

A.

overlapping -72 dBm coverage from two access points

B.

continuous -67 dBm coverage from one access point

C.

continuous -72 dBm coverage from one access point

D.

overlapping -67 dBm coverage from two access points
