NEW QUESTION # 117
An enterprise is using the wireless network as the main network connection for corporate users and guests. To ensure wireless network availability, two standalone controllers are installed in the head office APs are connected to the controllers using a round-robin approach to load balance the traffic. After a power cut, the wireless clients disconnect while roaming. An engineer tried to ping from the controller but fails.
Which protocol needs to be allowed between the networks that the controllers are Installed?
- A. IP Protocol 77

NEW QUESTION # 118
APs in a remote office recently have been converted from local mode to FlexConnect to take advantage of the local switching. After the change, remote wireless users report voice quality issues and bad quality on wireless IP phones while roaming. A debug is performed, and it is noticed that the 802.11r Fast Transition is not working as expected, like on local mode AP, though the same WLAN configuration is in place. What is the cause of the issue regarding the FlexConnect APs?
- A. They do not support 802.11r FT.
- B. They must be in a FlexConnect group to support 802.11r FT.
- C. They must be added into AP groups along with a common RF profile.
- D. They must be added to AP groups to support fast roaming methods.
Answer: B
Explanation:
802.11r BSS Fast Transition on FlexConnect Deployment
In a FlexConnect Deployment scenario, 802.11r BSS FT roaming is supported between APs within the same FlexConnect group. To enable seamless roaming, the 802.11r Key Cache is distributed to all the APs in the same FlexConnect Group. The Key Cache distribution is done by the Cisco WLC after the client device does the initial FT association through Central Authentication.
The Flex deployment supports both Over-the-Air and Over-the-DS roaming. Both the roaming scenarios are illustrated below:
Optimizations for FlexConnect Deployment
The 802.11r Fast Transition (FT) feature for FlexConnect mode APs is optimized such that the FT authentication request process and validation occur at Cisco AP itself and the Cisco AP itself sends FT authentication response. There is no change in the key derivation system.
NEW QUESTION # 119
An engineer at a global enterprise organization must ensure that a mesh deployment has the highest number of channels available to the backhnaul. regardless of region deployed. Which design meets this requirement?

- D. redundant controllers in the least restrictive regulatory domain
Answer: C

NEW QUESTION # 120
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. SSO needs to be enabled
- C. The secondary Cisco WLC needs a minimum of 50 base licenses
- D. The primary Cisco WLC is already set as the secondary unit.
Answer: C
Explanation:
If you want to convert any existing WLC as a Standby WLC, do so using the config redundancy unit secondary command in the CLI. This CLI command will only work if the WLC which is intended to work as Standby has some number of permanent license count. This condition is only valid for the 5508 WLC, where a minimum of 50 AP Permanent licenses are needed to be converted to Standby. There is no restriction for other WLCs such as the 5520, WiSM2, 7500, and 8500.

NEW QUESTION # 125
Refer to the exhibit.
An enterprise has offices spread around the globe. The APs are connected to different controllers installed in separate datacenters. The IT team wants to allow clients to roam from controllers in group ABC to controllers in group XYZ. Which feature must be incorporated in the design to accomplish this task?
- A. switch peer group
- B. mDNS gateway
- C. mobility lists
- D. workgroup bridge
Answer: C
Explanation:
In a Cisco wireless network, when designing for client roaming between access points (APs) that are connected to different controllers, especially in a global enterprise with multiple data centers, it is essential to ensure seamless client mobility. Mobility lists are used in such scenarios to define which controllers are allowed to participate in client roaming. This feature allows the APs connected to controllers within one group (e.g., Group ABC) to recognize and facilitate roaming clients from another group (e.g., Group XYZ). The mobility list is configured on each controller and includes the IP addresses of other controllers that should be considered part of the same mobility domain. When a client roams from an AP on one controller to an AP on another controller, if both controllers are in each other's mobility list, they will establish a mobility tunnel through which they exchange the client's context and security credentials. This ensures that the client can roam without re-authentication and maintains session continuity.
