Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 89

A wireless engineer is getting ready to perform a predictive site survey. The new network needs to support data and voice over wireless. Which two Cisco recommendations should be considered for the design? (Choose two.)

Answer options

• A. Set -19 dBm of separation between APs on the same channel.
• B. Use the 5 GHz radio band due to 40 MHz bandwidth capability.
• C. Use the 5 GHz radio band due to the 24 non-overlapping channels.
• D. Set the cell boundary to -67 dBm.
• E. Set the cell overlap to 15%

Correct answer: C, D

Explanation

Choosing the 5 GHz radio band for its 24 non-overlapping channels (C) is beneficial as it reduces interference and supports more simultaneous connections. Setting the cell boundary to -67 dBm (D) ensures adequate signal strength for reliable voice and data services. The other options either do not directly support these goals or suggest configurations that could lead to increased interference and reduced performance.
