Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 198

An engineer is designing a high-density WLAN that must support 100 concurrent users with 100 Mbps throughput consistently. The design allows for 20 Mbps per cell and per channel on the 5 GHz band. How many channels must the design use to provide 1 Mbps per user prior to RF overhead?

Answer options

• A. 5
• B. 10
• C. 15
• D. 20

Correct answer: A

Explanation

The correct answer is A because to support 100 users at 1 Mbps each, a total of 100 Mbps is required. Given that each channel provides 20 Mbps, dividing 100 Mbps by 20 Mbps per channel results in 5 channels needed. The other options are incorrect as they would not provide sufficient throughput for all users.
