350-401 Question 165
Single answerA network engineer is deploying a wireless network in a large warehouse. The warehouse has high ceilings and tall shelves, requiring specific coverage to minimize interference and provide adequate signal strength for handheld devices used by staff. Which combination of AP mode and antenna type would be most appropriate for this deployment?
- A
FlexConnect mode with an omnidirectional antenna
- B
Bridge mode with a directional antenna
- C
Local mode with an omnidirectional antenna
- D
Local mode with a directional antenna
Show answer and explanation
Correct answer: D
Explanation
In a large warehouse with high ceilings and tall shelves, the use of local mode ensures centralized control and optimized performance. A directional antenna is critical to focus the wireless signal into specific areas, providing better coverage and minimizing interference in a challenging RF environment. This combination best meets the requirements of the described scenario.
- A. Incorrect.
FlexConnect mode with omnidirectional antennas is typically used in remote sites or branch offices where connectivity to the central controller might be intermittent. It is not ideal for environments requiring precise coverage like a warehouse.
- B. Incorrect.
Bridge mode with a directional antenna is used for point-to-point or point-to-multipoint connections, such as connecting two buildings. It is unsuitable for providing client coverage within a warehouse.
- C. Incorrect.
Local mode with an omnidirectional antenna provides broad coverage, but it lacks the targeted signal focus needed for high-ceiling and shelf-dense environments such as a warehouse.
- D. Correct.
Local mode with a directional antenna is the most appropriate choice for a warehouse. Local mode ensures centralized management and monitoring, while directional antennas focus the signal in specific areas, reducing interference and improving signal strength in high-density environments.
