Implementing Cisco Wireless Network Fundamentals (WIFUND, legacy) — Question 64

What are requirements for VoWLAN?

Answer options

• A. RSSI -67
• B. SNR 25
• C. 20% overlapping cells
• D. SNR 40

Correct answer: C

Explanation

The correct answer is C, as having 20% overlapping cells ensures seamless handoff and coverage for VoWLAN. Options A and D specify signal-to-noise ratios which might not fully address the coverage needs for VoWLAN, while option B's SNR 25 is also insufficient for optimal performance.
