When designing a WLAN network to support both voice and context-aware services, which set of design principles should you follow? 

Answer options:

A. A voice and context-aware site survey can be one survey, and both voice and context-aware deployment recommendations can be implemented. APs that are not serving clients will be in monitor mode.
B. A context-aware site survey usually recommends deploying more APs because of the requirement for perimeter coverage and four corners of a floor. However, voice deployment recommendations should be adopted because of the mission-critical nature of voice traffic.
C. A voice and context-aware site survey can be one survey, but voice deployment recommendations take precedence over context-aware deployment recommendations because the context-aware survey usually recommends too many APs and might introduce too much co-channel interference, negatively affecting voice quality.
D. A voice and context-aware site survey can be one survey, but context-aware deployment recommendations take precedence over voice deployment recommendations because context-aware services require at least four APs to hear clients or tags at -75 dBm. An AP can provide adequate coverage to voice clients with acceptable SNR.
E. A voice and context-aware site survey can be one survey, but voice deployment recommendations take precedence over context-aware deployment recommendations. Context-aware surveys usually recommend too many APs, and APs need to be in local mode because APs in monitor mode spend too
