- B . The clients are only two stream 802.11ax clients
- C . Contention caused by an overlapping BSS
- D . Non-Wi-Fi interference in the channel
Rebekah McAdams was hired to perform a wireless packet analysis of your network. While performing the analysis, she noticed that many of the data frames were preceded by an RTS frame followed by a CTS frame.
What could cause this to occur? (Choose all that apply.)
- A . AP automatically enabled RTS/CTS mechanisms as a response to co-channel interference.
- B . An AP was manually configured with a low RTS/CTS threshold.
- C . A nearby cell phone is causing some of the nodes to enable a protection mechanism.
- D . Legacy 802.11b clients are connected to an 802.11g/n AP.
Which of the following are true about scanning? (Choose all that apply.)
- A . There are two types of scanning: passive and active.
- B . Stations must transmit probe requests in order to learn about local APs.
- C . The 802.11 standard allows APs to ignore probe requests for security reasons.
- D . It is common for stations to continue to send probe requests after being associated to an AP.
What term is used to describe the time differential between a primary signal and a reflected signal arriving at a receiver?
