When designing a WLAN network using Cisco 1142 APs to support both voice services (Cisco 7921 IP Phones) and data services, what design principles are true? (Choose 2)
The correct answer is A. 802.11n data rates should be enabled to improve overall performance even if the Cisco 7921 IP Phones C. Ensure proper floor coverage to ensure good voice quality (-67 dBm, 20% cell overlap, and 19 dB channel. See the full explanation below for the reasoning.

When designing a WLAN network using Cisco 1142 APs to support both voice services (Cisco 7921 IP Phones) and data services, what design principles are true? (Choose 2)
Options
- A802.11n data rates should be enabled to improve overall performance even if the Cisco 7921 IP Phones
- B802.11n data rates should not be enabled as the Cisco 7921 IP Phones are not 802.11n capable. As such,
- CEnsure proper floor coverage to ensure good voice quality (-67 dBm, 20% cell overlap, and 19 dB channel
- D-67 dBm, 20% cell overlap, and 19 dB channel separation is impossible to achieve. Therefore, a site survey
- ERRM should not be used as it is not designed for wireless voice services and will adjust the channel and
- FRRM should be used because it is the only way to ensure that channel and Tx power are configured to
