Wireless

Question 1

The original wireless standard ratified in 1997

Answer 1

802.11-1997 2.4 GHz 2Mbps

Question 2

HT (high throughput, introduced in 2009

Answer 2

802.11n 2.4GHz 5GHz 600Mbps

Question 3

no 2.4GHz, 5GHz 6.3 Gbps
VHT (very high throughput) introduced in 2013

Answer 3

802.11ac

Question 4

2.4 GHz and 5GHz, 4x802.11ac, Wi-Fi6, will operate on other bands too

Answer 4

802.11ax

Question 5

AP Mode
-Offers one or more functioning BSSs on specific channel
-During times it is not transmitting, the AP will scan the other channels to measure the level of noise, measure interference, discover rogue devices, and match against intrusion detection systems (IDS) events.

Answer 5

Local AP Mode

A lightweight AP is normally in local mode when it is providing BSSs and allowing client devices to associate to wireless LANs. When an AP is configured to operate in one of the other modes, local mode (and the BSSs) is disabled.

Question 6

AP Mode
The AP does not transmit at all, but its receiver is enabled to act as a dedicated sensor. The AP checks for IDS events, detects rogue access points, and determines the position of stations through location-based services

Answer 6

Monitor AP Mode

Question 7

AP Mode
An AP at a remote site can locally switch traffic between an SSID and a VLAN if its CAPWAP tunnel to the WLC is down and if it is configured to do so

Answer 7

FlexConnect AP Mode

Question 8

AP Mode
An AP dedicates its radios to receiving 802.11 traffic from other sources, much like a sniffer or packet capture device. The captured traffic is then forwarded to a PC running network analyzer software such as Wildpackets Omnipeek or WireShark, where it can be analyzed further.

Answer 8

Sniffer AP Mode

Question 9

AP mode
An AP dedicates itself to detecting rogue devices by correlating MAC addresses heard on the wired network with those heard over the air. Rogue devices are those that appear on both networks

Answer 9

AP Rogue Detector mode

Question 10

AP Mode
An AP becomes a dedicated bridge (point-to point or point to multipoint) between two networks. Two APs in bridge mode can be used to link two locations separated by a distance. Multiple APs in this mode can form an indoor or outdoor mesh network

Answer 10

AP Bridge Mode

Question 11

AP mode
FlexConnect operation is enabled on a mesh AP

Answer 11

Flex+Bridge AP mode

Question 12

AP mode
The AP dedicates its radios to spectrum analysis on all wireless channels. You can remotely connect a PC running software such as MetaGeek Chanalyzer or Cisco Spectrum Expert to the AP to collect and analyze the spectrum analysis data to discover sources of interference.

Answer 12

SE-Connect AP mode
