A client complains of low data rates on his computer. When you evaluate the situation, you see that the signal strength is -84 dBm and the noise floor is -96 dBm. The client is an 802.11ac client and connects to an 802.11ac AP. Both the client and AP are 2x2:2 devices. What is the likely cause of the low data rate issue?
Weak signal strength
CAT5e cabling run to the AP
Too few spatial streams
Lack of support for 802.11n

An IEEE 802.11 amendment is in the daft state. What impact does this draft amendment have on the 802.11 standard?
Devices will be released based on the draft amendment and the draft amendment features are part of the standard.
No impact: Until an amendment is ratified, it does not become part of the standard.
No impact: Draft amendments do not become part of the standard until a working group is formed.
The standard is changed to reflect the new capabilities as soon as an amendment enters the draft stage.

What statement about the beamwidth of an RF antenna is true?
Horizontal and vertical beamwidth are calculated at the points where the main lobe decreases power by 3 dB.
The beamwidth patterns on an antenna polar chart indicate the point at which the RF signal stops propagating.
When antenna gain is lower, the beamwidth is also lower in both the horizontal and vertical dimensions.
Vertical beamwidth is displayed (in degrees) on the antenna’s Azimuth chart.

You are the network administrator for ABC Company. Your manager has recently attended a wireless security seminar. The seminar speaker taught that a wireless network could be hidden from potential intruders if you disabled the broadcasting of the SSID in Beacons and configured the access points not to respond to Probe Request frames that have a null SSID field. Your manager suggests implementing these security practices. What response should you give to this suggestion?
Any 802.11 protocol analyzer can see the SSID in clear text in frames other than Beacons frames. This negates any security benefit of trying to hide the SSID in Beacons and Probe Response frames.
To improve security by hiding the SSID, the AP and client stations must both be configured to remove the SSID from association request and response frames. Most WLAN products support this.
Any tenants in the same building using advanced penetration testing tools will be able to obtain the SSID by exploiting WPA EAPOL-Key exchanges. This poses an additional risk of exposing the WPA
