Question

Quizplus · Accepted Answer

IEEE802.11n standard supports quality of service (QoS) to deliver time sensitive frames without delays. The other options are incorrect as CSMA/CD is not used in IEEE802.11n, it supports multiple-input-multiple-output, it works in both 2.4GHz and 5GHz bands, and it does not mandate RTS/CTS for media access control.
