A customer has two Cisco 550B WLCs that manage all the access points in their network and provide N+1 redundancy and load balancing. The primary Cisco WLC has 60 licenses and the secondary Cisco WLC has 40. The customer wants to convert the N+1 model to an HA model and provide SSO. Configuration must be performed during a maintenance window. After performing all the configurations on both controllers, the config redundancy unit secondary command is issued on the secondary Cisco WLC and it fails. Which parameter needs to be in place to complete the configuration?

A. A cable in the RP port B. The secondary Cisco WLC needs a minimum of 50 base licenses C. The primary Cisco WLC is already set as the secondary unit. D. SSO needs to be enabled Answer: Option B.

A client roams between two APs that are registered to two different controllers, where each controller has an interface in the client subnet.

Refer to the exhibit. A client roams between two APs that are registered to two different controllers, where each controller has an interface in the client subnet. Both controllers are running AireOS. Which scenario explains the client roaming behavior? A. Controllers exchange mobility control messages (over UDP port 16666), and the client database entry is moved from the… Read More »

A customer is running a guest WLAN with a foreign/export-anchor setup. There is one anchor WLC in the US and two in Europe. Anchor WLC priorities are used to prefer local anchors. During a routine network audit, it is discovered that a large number of guest client sessions in the US are anchored to the WLCs in Europe. Which reason explains this behavior?

A. The foreign WLC failed and recovered. B. The US anchor WLC failed and recovered. C. The US anchor WLC is anchored to itself with a priority value of zero. D. The anchor WLC is in the same mobility group. Answer: Option B. Explanation: No answer description available for this question. Show AnswerDiscussion The post A customer is… Read More »

Two Cisco 5520 Wireless LAN Controllers are managing all access points 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 the primary configured controller. Which configuration task fixes this issue?

A. Enable AP fallback globally on the WLC. B. Change the AP Failover Priority to critical. C. Use DHCP Option 43 and specify WLC in location A as primary. D. Configure the WLC in location A as primary using the CAPWAP AP Controller IP Address command on all the location A access points. Answer: Option A. Explanation: No… Read More »

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 -19 dBm of separation between APs on the same channel. B. Use the 5 GHz radio band due to 40 MHz bandwidth capability. C. Use the 5 GHz radio band due to the 24 non-overlapping channels. D. Set the cell boundary to -67 dBm. E. Set the cell overlap to 15% Answer: Option C, D. Explanation: … Read More »
