Cisco Designing Cisco Wireless Networks Sample Questions:

1. A customer wants a network engineer to design a Cisco wireless solution that will have redundancy through SSO and LAG. APs in the executive office must reassociate to the WLC as soon as possible in the event of a failure. The WLCs are located in a remote data center. The head office uses a WAN for connectivity with the data center. Which priority must be incorporated in the design to be assigned to the executive APs?

A) low
B) medium
C) critical
D) high

2. 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 UNII-2E 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?

A) DFS detection
B) band select
C) RxSOP
D) 802.11w

3. A wireless engineer is getting ready to perform a predictive site survey. The new network needs to support data and voice over wireless. Which two Cisco recommendations should be considered for the design?
(Choose two.)

A) Set the cell boundary to -67 dBm.
B) Set the cell overlap to 15%
C) Use the 5 GHz radio band due to 40 MHz bandwidth capability.
D) Set -19 dBm of separation between APs on the same channel.
E) Use the 5 GHz radio band due to the 24 non-overlapping channels.

4. A customer has two Cisco 5520 WLCs that manage all APs throughout the network. The WLCs are in different locations to provide geographical redundancy. A mobility group has been configured on both WLCs and has an UP status on both controllers. The APs in location A are statically configured to use controller A as the primary and controller B as the secondary. If the WLC in location A goes offline, the APs successfully join the WLC in location B, but they do not fail over to their primary configured controller when it recovers.
Which configuration task fixes the issue?

A) Enable AP fallback globally on the WLC.
B) Use DHCP Option 43 and specify WLC in location A as primary.
C) Configure the WLC in location A as primary using the CAPWAP AP Controller IP Address command on all the location A access points.
D) Change the AP Failover Priority to critical.

5. A hospital has a Cisco Catalyst 9800 Series Wireless Controller in an SSO solution deployed in the primary data center. The hospital plans to increase redundancy in the wireless environment. Management decides to deploy an extra Catalyst 9800 WLC offsite to another data center on a different subnet. A WAN link connects the data centers with a firewall at both ends. Which two design approaches must the engineer take to ensure that the APs can fail over? (Choose two.)

A) Open UDP ports 16666 and 16667 between the wireless controllers.
B) Create a static RF group leader on one of the wireless controllers.
C) Open HTTPS port 443 between the wireless controllers.
D) Create a mobility group with the same names on both wireless controllers.
E) Create a mobility tunnel between the wireless controllers.
