PW0-270 Question #24: Real Exam Question with Answer & Explanation
The correct answer is A. High collision rates due to dense population of voice stations and no admission control C. High multipath conditions due to an RF environment with highly reflective materials D. 2.4 GHz ISM band interference from sources such as wireless video cameras and analog phones. See the full explanation below for the reasoning.
Question
ABC Company is having VoWiFi latency problems on their 802.11g WLAN. A wireless administrator has noticed in the phone's client utilities software that the MAC CRC Error count is higher on stations with problems than on those client stations without problems. A high MAC CRC Error count is attributable to which of the following? (Choose 3)
Options
- AHigh collision rates due to dense population of voice stations and no admission control
- BTwo access points with overlapping coverage on a single channel
- CHigh multipath conditions due to an RF environment with highly reflective materials
- D2.4 GHz ISM band interference from sources such as wireless video cameras and analog phones
- ECo-located DCF and EDCA access points that are using non-overlapping 2.4 GHz channels
- FDynamic Rate Switching algorithms that decrease data rates for latency-sensitive applications
