Refer to the exhibit. A network engineer has identified that during a recent controller failure, several APs failed over to the tertiary controller instead of the secondary controller. The configuration from one of the APs is provided. Which design consideration led to the issue?

An engineer is reducing the subnet size of the corporate WLAN by segmenting the VLAN into smaller subnets. Clients will be assigned a subnet by location.
Which type of groups can the engineer use to map the smaller subnets to the corporate WLAN?

An engineer must perform a predictive design for a wireless network. The customer has devices that can tolerate at most 100 ms of delay when roaming. Which design criteria must be used?

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?

A company has 10 access point licenses available on their backup Cisco WLC and their primary Cisco WLC is at full capacity, 5 access points are set to high failover priority and 7 access points are set to critical failover priority.
During a failure, not all critical access points failed over to the backup Cisco WLC.
Which configuration is the cause of this issue?

Refer to the exhibit. An enterprise is using wireless as the main network connectivity for clients.
To ensure service continuity, a pair of controllers will be installed in a datacenter.
An engineer is designing SSO on the pair of controllers.
What needs to be included m the design to avoid having the secondary controller go into maintenance mode?

Refer to the exhibit. During a post Mesh deployment survey, an engineer notices that frame cessions occur when MAP-1 and MAP-3 talk to RAP-2.
Which type of issue does the engineer need to address in the design?

Where must the APs be mounted when used in a high-density wireless network to provide 6 dB to
20 dB of attenuation to a cell?

Which option is an enhancement of enabling WMM on an AP?

An engineer configured the optimized client roaming on Cisco WLC with an RSSI threshold of
72dBm. Clients report frequent disconnections. What must be configured for the AP to guide the client to a better AP?

An engineer must speed up the reauthentication delays that are being experienced on the wireless infrastructure by deploying a key-caching mechanism. Which mechanism must be configured?

An engineer created a design where the HQ has a Cisco 5520 Wireless LAN Controller with 2000 APs associated to it. If a controller at one of the remote sites fails, the APs at that site fall back to a central controller. Global AP Failover Priority must be enabled. Which design approach must be taken to prevent the critical APs at HQ from going down and still allow APs to failover to the HQ controller?

An engineer is designing a wireless network for a manufacturing facility that has high steel shelves. Which antenna type must be used?

An engineer must perform a Layer 2 survey for a mining facility. Which type of antenna does the engineer use in the mine shaft?

Campus users report a poor wireless experience. An engineer investigating the issue notices that in high-density areas the wireless clients fail to switch the AP to which are automatically connected. This sticky client behavior is causing roaming issues.
Which feature must the engineer configure?

An IT administrator is trying to establish the criteria for a predictive coverage design. The environment is a mix of 802.11g data and voice. Which minimum coverage with SNR 25 aligns with Cisco best practice?

A customer with two Cisco 5520 WLCs that work as a primary and secondary had some switching issues and the primary controller lost connectivity. Immediately all APs went to discovery and joined the secondary controller. After recovering from the issue, the primary controller is online, but no APs return to it. All APs remain in the secondary controller. Which setting advises the APs to return to their primary controller?

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?

A network engineer is retrofitting an existing building wired with Category 5e with Cisco Aironet
3800 Series APs and mGig switches. Which cable length allows for 5G operation?
