NEW QUESTION # 50
Refer to the exhibit.
Client A is roaming from AP1 on WLC1 to AP2 on WLC2. The client roams between two APs registered to two different controllers. The WLAN on the two controllers is on a different subnet. Which scenario explains the client's roaming behavior?
- A. The client database remains in the mobility anchor controller and it is not cop-ied or moved.
- B. The client database entry is different than that of Layer 2 roam. (Instead of cop-ying, it moves the database to the new controller.)
- C. The client database entry is different than that of Layer 2 roam because the cli-ent database is neither moved nor copied into the new controller.
- D. The client database entry is different than that of Layer 2 roam. (Instead of mov-ing, it copies the database to the new controller.)
Answer: D
NEW QUESTION # 51
A customer uses a Cisco 5520 WLC that is connected via a single 10-GB interface to manage the wireless network. The wireless network includes 500 APs for the campus network. The customer wants to add 300 APs and is concerned about traffic load and lack of redundancy. The purchase of a second controller is not an option. Which design approach mitigates the customer concerns?
- A. Implement a vWLC and configure N+1 redundancy with the WLC.
- B. Implement a vWLC and configure SSO with the WLC.
- C. Connect a second 10-GB interface on the WLC and implement LAG.
- D. Connect a second 10-GB interface on the WLC and set the port as a secondary port.
Answer: C
Explanation:
The Cisco 5520 WLC supports Link Aggregation (LAG), which allows multiple physical interfaces to be treated as a single logical channel. By connecting a second 10-GB interface and implementing LAG, the customer can increase the throughput capacity and provide redundancy without the need for a second controller. This approach also simplifies network design and management by reducing the number of IP addresses needed for the controllers and APs.
NEW QUESTION # 52
A wireless consultant reviewing the installation of an old wireless network. The existing AireOS controllers are running software version 6.0.4539:44024. The customer is using OEAP and wants to keep this functionality. Which licenses should the consultant propose with the latest controller software version?
- A. Base
- B. Advanced
- C. WPlus
- D. Premium
Answer: A
Explanation:
The base license supports OfficeExtend access points, and Before 6.0.196, licenses were separated into BASE and PLUS types.-With 6.0.196 and all later code (including 7.0 releases), all features included in a Wireless LAN Controller Wplus license are now included in the base license.

NEW QUESTION # 54 
Refer to the exhibit. A client roams between two APs that are registered to two different controllers, where each controller has an interface in the client subnet. Both controllers are running AireOS. Which scenario explains the client roaming behavior?
- A. Controllers exchange mobility control messages (over UDP port 16666) and the client database entry is moved from the original controller to the new controller.
- B. Controllers exchange mobility control messages (over UDP port 16666) and a new client session is started with the new controller.
- C. Controllers do not exchange mobility control messages (over UDP port 16666) and the client database, entry is not moved from the original controller to the new conrtoller.
- D. Controllers exchange mobility control messages (over UDP port 16666) and the client database entry is tunneled from the original controller to the new controller.
Answer: A

NEW QUESTION # 56
An engineer is designing a new wireless network. The network needs to meet these requirements:
- support a high wireless client concentration
- support data over wireless
- support voice over wireless
- avoid interference
Which design approach should be taken?
- A. 5 GHz frequency band without channel bonding, to support 20 MHz channels
- B. 5 GHz frequency band with channel bonding, to support 40 MHz channels
- C. 5 GHz frequency band with channel bonding, to support 80 MHz channels
- D. 2.4 GHz frequency band without channel bonding to support 20 MHz channels
Answer: A
Explanation:
To avoid interference you have to have a higher SNR as possible. While doing Channel bonding you add noise. Besides, high wireless clients concentration demand needs to have a high SNR and to avoid Co-Channel interference. I quote: "One of the hallmarks of a high-performing WLAN is channel reuse. This is the practice of deploying channels in such a manner that they limit the amount if CCI introduced into the environment. The best way to achieve this is by having as many channels to deploy as possible. While a 20MHz channel will not achieve the higher data rates that are advertised with 80MHz, clients can still reach acceptable speeds, allowing you to optimally use each bit of available airtime."

NEW QUESTION # 57
An engineer must install an outdoor wireless network for an area with a direct line of sight. The outdoor APs are in an open area with of harsh weather. Which two parameters must the engineer consider to prevent an outdoor wireless outage? (Choose two.)
- A. antenna cable grounding
- B. cable strength
- C. cable length
- D. elimination of trees
- E. lightning arrestor installation
Answer: A,E
Explanation:
For outdoor wireless networks, especially in open areas prone to harsh weather, it's crucial to install lightning arrestors to protect against electrical surges caused by lightning strikes. Additionally, grounding the antenna cables helps dissipate any electrical charge that could damage the equipment.

NEW QUESTION # 60
An engineer is designing an outdoor mesh network to cover several sports fields. The core of the network is located in a building at the entrance of a sports complex. Which type of antenna should be used with the RAP for backhaul connectivity?
- A. 2.4 GHz. 14-dBi omnidirectional antenna
- B. 5 GHz. 14-DBi patch antenna
- C. 5 GHz. 8-dBi omnidirectional antenna
- D. 2.4 GHz. 8-dBi patch antenna
Answer: B
Explanation:
In an outdoor mesh network designed to cover sports fields, a 5 GHz, 14-dBi patch antenna is suitable for the RAP for backhaul connectivity. The higher gain and directional nature of a patch antenna help in focusing the signal over longer distances and in specific directions, which is ideal for connecting various points in a large outdoor area5.
