Ruckus Certified Wireless Architect (RCWA) — Question 10

When designing a WLAN for VoIP, what percentage of airtime utilization and RSSI threshold should be maintained?

Answer options

• A. under 75% utilization and -70dBm minimum
• B. above 60% utilization and -69dBm minimum
• C. under 50% utilization and -65dBm minimum
• D. above 55% utilization and -60dBm minimum

Correct answer: C

Explanation

Option C is correct because maintaining under 50% utilization ensures sufficient bandwidth for VoIP, while a minimum RSSI of -65dBm guarantees adequate signal strength for clear communication. The other options either exceed optimal utilization levels or set too high a minimum RSSI, which could compromise call quality.
