NSE 8 – Network Security Expert — Question 2

Which three statements about throughput on a wireless network are true? (Choose three.)

Answer options

• A. A wireless device labelled as 300 Mbps should be expected to provide a throughput of 300Mbps.
• B. Be careful to ensure the capabilities of the wireless clients match those of the access points, in order to achieve higher throughput.
• C. Reducing the duty cycles of the wireless media by generating fewer beacons may improve throughput.
• D. Because of the higher level of RF noise that is typical in the 2.4 GHz ISM band, throughput of 2.4 GHz devices will typically be less than 5 GHz devices.
• E. Because of the full-duplex nature of the medium and the minimal overhead generated by CSMA/CA, the actual aggregate throughput is typically close to the

Correct answer: D

Explanation

Statement D is correct because the 2.4 GHz band is more susceptible to interference, leading to reduced throughput compared to the 5 GHz band, which has less interference. Options A, B, and C do not universally apply to all scenarios of wireless throughput, making them less reliable statements in this context.
