You are evaluating a connection that states the data rate is 150 Mbps. What is the expected throughput of this connection?

• A.54 Mbps because that is the actual maximum throughput of an 802.11 connection
• B.150 Mbps because the data rate is equal to the throughput
• C.More than 150 Mbps because of compression
• D.Less than 150 Mbps because of 802.11 overhead and contention

As a consultant, you've been hired by XYZ Company to provide recommendations about client device selection, operation, and interoperability. What information should be considered to help them choose the right WLAN client devices?

• A.802.11n OFDM is more susceptible to high-power, narrowband interference than 802.11a
• B.When HR/DSSS devices are present, VHT MCS rates are disabled for the entire BSS.
• C.802.11ac devices support the features of the VHT PHY only in the 5 GHz frequency band.
• D.802.11ac is not backwardly compatible with 802.11n or 802.11a.
• E.In order to earn Wi-Fi Alliance certification, 802.11n clients stations are required to support both
  2.4 and 5 GHz frequencies
