NEW QUESTION # 134
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 data RSSI to -90db.
- B. Enable Optimize Roaming.
- C. Enable CHDM.
- D. Enable 802.11k.
Answer: B
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 # 135
An engineer is designing a wireless deployment for a university auditorium. Which two features can be used to help deal with the issues introduced by high AP count? (Choose two.)
- A. RXSOP
- B. TSPEC
- C. TPC
- D. LSS
- E. DFS
Answer: A,C
Explanation:
RXSOP (Receive Start of Packet Detection Threshold) and TPC (Transmit Power Control) are two features that can help manage the challenges associated with a high AP (Access Point) count in a dense environment like a university auditorium. RXSOP can be adjusted to refine how APs differentiate between noise and valid packets, which is particularly useful in high-density areas where multiple APs might otherwise respond to the same signal. TPC helps in managing the transmit power of APs, allowing for better coverage and reduced interference among APs that are in close proximity to each other.

NEW QUESTION # 136
An engineer must create data-link redundancy for the company's Cisco Wireless LAN Controller. The engineer has decided to configure LAG-based redundancy instead of port-based redundancy. Which three features of LAG-based redundancy influenced this decision? (Choose three.)
- A. The same port has multiple untagged dynamics interfaces.
- B. All interface traffic passes as long as one port is up.
- C. Packets are always sent out on the same port they are received on.
- D. Interface connection to two separate nonstacked switches is available.
- E. Ports are grouped into multiple LAGs.
- F. Full bandwidth of all links is available.
Answer: B,E,F
Explanation:
LAG-based redundancy is chosen for its ability to provide continuous connectivity as long as one port in the LAG is operational (B), utilize the full bandwidth capacity of all the links in the LAG (E), and allow for the grouping of ports into multiple LAGs for increased redundancy and bandwidth (F).

NEW QUESTION # 139
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?
- A. A rule is needed at the firewall to allow UDP port 16666 for communication towork.
- B. A rule is needed at the firewall to allow TCP port 97 for communication to work.
- C. A rule is needed at the firewall to allow UDP port 97 for communication to work.
- D. A rule is needed at the firewall to allow TCP port 16666 for communication to work.
Answer: A
Explanation:
Guest anchoring requires mobility tunnels to be established between the foreign and anchor WLCs. For these tunnels to function, the firewall must allow specific ports for communication. UDP port 16666 is the port used for mobility traffic in Cisco wireless networks, and if it is not allowed through the firewall, MPING and mobility tunnels will fail.

NEW QUESTION # 140
An engineer working for an enterprise deployed multiple Cisco WLCs. A controller that sits in the R&D division is connected through a firewall and is part of the same mobility group. The engineer must ensure that the mobility tunneling is available through the firewall and test it as R&D engineers roam the production ..within their department. How is this requirement met?
- A. mapping on UDP port 16666 and mapping on Protocol 97 between management ports
- B. mapping on UDP port 16667 and mapping on Protocol 96 between management ports
- C. mapping on UDP port 16667 and mapping on Protocol 97 between management ports
- D. mapping on UDP port 16666 and mapping on Protocol 96 between management ports
Answer: A
Explanation:
For mobility tunneling through a firewall in a Cisco wireless network environment, UDP port 16666 must be open along with IP Protocol number '97', which is used for Encapsulating Security Payload (ESP) traffic typically found in IPsec tunnels. By ensuring these ports are mapped correctly through the firewall, R&D engineers can roam within their department while maintaining a secure mobility tunnel.

- D. MAP
Answer: C
NEW QUESTION # 142
An engineer added an AP to a deployment after a post-installation site survey. The engineer then notices an increase in co-channel interference and retransmissions. Which two features help mitigate the issue? (Choose two.)
- A. Dynamic Channel Assignment
- B. Coverage Hole Detection
- C. Enhanced Distributed Channel Access
- D. Transmit Power Control
- E. Cisco Compatible Extensions
Answer: A,D
Explanation:
To mitigate increased co-channel interference and retransmissions after adding an AP, Transmit Power Control (TPC) and Dynamic Channel Assignment (DCA) can be effective. TPC adjusts AP transmit power based on real-time analysis of the wireless environment, reducing interference by lowering power where necessary. DCA dynamically changes channel assignments based on current RF conditions to optimize performance and minimize interference.

Refer to the exhibit. What is the main reason why the Wi-Fi design engineer took a different approach than installing the APs in the offices, even though that installation provides better coverage?
- A. power supply considerations
- B. transmit power considerations
- C. aesthetics
- D. antenna gain
Answer: C
Explanation:
For aesthetic reasons, facilities management has decided that access points will not be placed within any of the executive offices or conference rooms located between the hallway corridors and the physical perimeter. Because of these restrictions, our convex hull now lies at the outside edge of the corridor (indicated by the blue rectangle) and not at the true physical perimeter of the floor.

NEW QUESTION # 154
An engineer is designing a solution where guests terminate on an anchor controller in the DMZ. The engineer is having issues and wants to test connectivity between members of a mobility group. Which command must be issued to test whether a mobility control packet is able to be reached over the management interface?
- A. mapping
- B. tracert
- C. show logging
- D. mapping
Answer: B
Explanation:
The 'tracert' command is used to test connectivity between members of a mobility group by tracing the path that mobility control packets take over the network. This command helps identify any potential issues with the route that the packets are taking, which could affect the ability of guests to connect to the anchor controller in the DMZ.
