NEW QUESTION # 133
An engineer needs a wireless design to provide redundancy for APs at remote sites that are connected to Cisco 3504 Wireless LAN Controllers. The central Cisco 5520 Wireless LAN Controller supports 2000 APs and has 1975 access points associated to it. The engineer decides that not all APs at the remote sites must remain functional in the event of a failure. How does the engineer ensure that the most important access points at the remote sites remain online while not impacting the main site?
- A. Enable Global AP Fail over Priority, set the 1975 APs to a priority of "high", and set the 25 most important APs at the remote sites to "critical".
- B. Enable AP Fallback Mode, set the 1975 APs to a priority of "high", and set the 25 most important APs at the remote sites to "critical". C. Enable Global AP Fail over Priority, leave the 1975 APs at the default priority, and set the most important APs at the remote sites to "low".
- C. Enable AP Fallback Mode, leave the 1975 APs at the default priority, and set the most important APs at the remote sites to "high".
Answer: A
Explanation:
To ensure that the most critical APs at remote sites remain functional in the event of a failure, the Global AP Failover Priority feature can be used. By setting the priority of the most important APs to "critical", these APs will be given precedence over others during a failover scenario. This allows the engineer to prioritize which APs should remain online without impacting the main site's APs, which are set to a "high" priority.

Refer to the exhibit. Which two statements about Cisco Prime Infrastructure are true? (Choose two.)
- A. It shows the planning mode feature in Cisco Prime Infrastructure.
- B. It shows the map editor feature in Cisco Prime Infrastructure.
- C. Controllers must be synchronized with Cisco Prime Infrastructure for planning mode to work.
- D. Planning mode requires a special license in Cisco Prime Infrastructure.

Answer: A,C
NEW QUESTION # 138
Refer to the exhibit.
A WLC SSO pair is set up. Which failure scenario causes a split-brain scenario?
- A. VSL is down.
- B. Two distribution ports on the active WLC are down.
- C. RP is down.
- D. One distribution port on the active WLC is down.
Answer: A
Explanation:
The Virtual Switching Link (VSL) is essential for communication between the active and standby Wireless LAN Controllers (WLCs) in a Stateful Switch Over (SSO) setup. If the VSL goes down, it can lead to a split-brain scenario where both WLCs assume they are active, causing network disruptions and inconsistencies in client handling.

NEW QUESTION # 140
A rapidly expanding company has tasked their network engineer with wirelessly connecting a new cubicle area with Cisco workgroup bridges until the wired network is complete. Each of 42 new users has a computer and VoIP phone.
How many APs for workgroup bridging must be ordered to keep cost at a minimum while connecting all devices?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-1/configuration- guide/b_cg81/workgroup_bridges.pdf The WGB supports a maximum of 20 wired clients. If you have more than 20 wired clients, use a bridge or another device.
NEW QUESTION # 141
An engineer is working for an enterprise and deployed a Cisco 9800 Series Wireless Controller. The wireless infrastructure serves the employees and guest users across the company. The engineer must configure the controller to alleviate the sticky client issue in the deployment. Which action resolves the issue?
- A. Enable 802.11k.
- B. Enable data RSSI to -90db.
- C. Enable CHDM.
- D. Enable Optimize Roaming.
Answer: D
Explanation:
The sticky client issue occurs when a wireless client device clings to a suboptimal access point instead of roaming to a better one with a stronger signal. Enabling Optimize Roaming on the Cisco 9800 Series Wireless Controller can alleviate this issue. This feature prompts clients to roam by disassociating them when their signal strength drops below a threshold, encouraging them to seek a better connection.
NEW QUESTION # 142
An engineer must perform a pre-deployment site survey for a new building in a high-security area. The design must provide a primary signal RSSI of -65 dBm for the clients. Which two requirements complete This design? (Choose two)
- A. WLC model
- B. AP model
- C. Number of clients
- D. Site access
- E. HAVC access
Answer: B,C
Explanation:
For a pre-deployment site survey, it's important to know the AP model to understand the capabilities and coverage pattern of the APs. Additionally, knowing the number of clients helps to design a network that can handle the expected client density.

NEW QUESTION # 143 
Refer to the exhibit. During a post Mesh deployment survey, an engineer notices that frame collisions occur when MAP-1 and MAP-3 talk to RAP-2 Which type of issue does the engineer need to address in the design?
- A. co-channel interference
- B. backhaul latency
- C. hidden node
- D. exposed node
Answer: C
Explanation:
The issue described is indicative of a hidden node problem, where MAP-1 and MAP-3 cannot hear each other's transmissions but can both communicate with RAP-2. This leads to frame collisions as both MAPs may attempt to transmit at the same time, unaware of the other's actions. The design needs to address this by implementing mechanisms such as RTS/CTS or adjusting the placement of the APs to avoid this issue.

NEW QUESTION # 146
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. The secondary Cisco WLC needs a minimum of 50 base licenses
- B. SSO needs to be enabled
- C. The primary Cisco WLC is already set as the secondary unit.
- D. A cable in the RP port
Answer: A
Explanation:
NEW QUESTION # 147
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. WLC 7.5 code or more recent
- B. 10 sec RTT
- C. controller high availability pair with one of the WLCs having a valid AP count license
- D. redundant WLC
- E. back-to-back direct connection between WLCs
Answer: C,D
Explanation:
To support high availability, the design must include redundant Wireless LAN Controllers (WLCs) to ensure service continuity in case of a failure. Additionally, having a high availability pair with one WLC holding a valid AP count license ensures that all APs can remain connected and services continue without interruption during failover.
