350-401 Question 168
Single answerA network engineer is deploying a Cisco wireless network in a warehouse with high ceilings and large metal shelves that obstruct line-of-sight. The goal is to provide uniform coverage throughout the facility while minimizing interference. Which combination of AP mode and antenna type would best suit this environment?
- A
FlexConnect mode with an omnidirectional antenna
- B
Local mode with a directional patch antenna
- C
Bridge mode with a sector antenna
- D
Monitor mode with an omnidirectional antenna
Show answer and explanation
Correct answer: B
Explanation
In a warehouse environment with high ceilings and obstructions, the best approach is to use Local mode, which provides optimal performance for enterprise APs, along with a directional patch antenna. This combination allows focused coverage in specific areas while minimizing interference caused by reflective surfaces and obstructions like metal shelves. Other modes and antenna types either do not address the requirements of the scenario or are intended for different deployment use cases.
- A. Incorrect.
FlexConnect mode is typically used for remote site deployments where the WAN link is unreliable. While an omnidirectional antenna can provide broad coverage, it is not ideal for targeted areas with obstructions like a warehouse, making this option unsuitable.
- B. Correct.
Local mode is the most common mode for wireless APs in enterprise environments, offering the best performance. A directional patch antenna is ideal for focusing the signal in specific areas, which helps mitigate interference and obstructions in environments like a warehouse.
- C. Incorrect.
Bridge mode is used for point-to-point or point-to-multipoint wireless connectivity between buildings, not for providing indoor coverage. A sector antenna is also typically used for outdoor deployments, making this combination unsuitable for a warehouse.
- D. Incorrect.
Monitor mode is used for spectrum analysis and detecting rogue devices, not for providing client connectivity. An omnidirectional antenna would not address the need for focused coverage in a warehouse environment.
