A customer uses a Cisco Catalyst 9800 Series wireless controller to manage all of the APs for a campus network. Secure guest access is required for the guest network. A Cisco 5520 anchor controller is deployed within a DMZ. Which design approach ensures that the mobility tunnel is established successfully between the wireless controller and the anchor controller?
An engineer is designing a wireless network to support high availability. The network will need to support the total number of APs and client SSO. Live services should continue to work without interruption during the failover Which two requirements need to be incorporated into the design to meet these needs? (Choose two.)
A university wants to deploy a high density of APs in an area where a high number of users congregate. Which functionality allows the university to optimize the RF settings tor APs that operate In different environments or coverage zones?
During a client roaming event, which device is responsible for communicating the new Layer 2 EID mapping of a wireless supplicant to the fabric domain?
How should the concept of mobility domains and mobility groups be explained to a customer?
A network engineer is designing a new wireless network for a campus 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 network engineer is managing a wireless network for a large corporate campus with the configuration.
•Two Cisco Catalyst 9800 Series Wireless Controllers: WLC1 and WLC2. both running Cisco IOS XE Software version 17.9.5. These controllers are configured in the same mobility group, named CorpMobility. to enable seamless roaming (or clients across the campus.
•The WLAN Guest is deployed on both controllers to provide internet access for visitors. Due to the company's strict security policies, all guest traffic must be anchored to WLC2 for centralized internet access and firewall enforcement. •Client data traffic from the Guest WLAN on WLC1 be tunneled to WLC2. ensuring consistent policy application regardless of where the client connects.
•The mobility tunnel between WLC1 and WLC2 is established over the campus backbone network, which occasionally experiences latency spikes due to high traffic loads. Which set of actions should the engineer take to validate the mobility tunneling for the control and data paths?
When designing for voice over WLAN, what is the recommended cell overlap percentage between adjacent APs?
Which IEEE standard enables Fast BSS Transition (FT) for seamless roaming?
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?
Guest anchoring is configured for a newly created SSID for your company. It has been noticed that the mobility tunnels are not up, and that MPING fails from your foreign WLC to the anchor WLC. What is the reason that it is failing?
Which authentication method is most scalable for enterprise WLAN deployments?
Which wireless survey type is performed without APs installed, using simulated AP
locations?
A customer asks an engineer to explain the concept of mobility domains and mobility groups. Which statement does the engineer respond with?
What is the primary purpose of a validation survey?
Users who leave the office with a wireless headset must be able to hand oft the voice call with minimal disruption. The engineer drafted four possible Door plans for AP placement:
• red dots and arrows represent the direction of travel
• blue dots represent the AP placements
Which floor plan provides the requested functionality?
A)
B)
C)
D)
WLC SSO is set up between two WLCs in a service provider network serving public spaces. On WLC failover, it is noticed that only about half of the original client count is now showing on the secondary WLC, although it is currently showing the role as active. Which design side case explains the issue?
Which design document contains detailed RF coverage maps, AP placement, and antenna orientation?
An engineer must ensure that the wireless network can accomplish fast secure roaming by way of caching keys on the access points. Which key caching mechanism is enabled by default on a Cisco AireOS WLC?
An engineer is designing a point-to-multipoint mesh network. Which two AP configurations must be completed for a site survey? (Choose two.)
