MR66

20
Q

Which Cisco AP model supports ac Wave 2?

A

1850 (standard)

3700 with an optional module

21
Q

List the 8 special-purpose modes that a LAP can be configured to operated?

A 
Local
Monitor
FlexConnect
Sniffer
Rogue detector
Bridge
Flex + Bridge
SE-Connect
22
Q

What is the SE-Connect mode used for on a Cisco LAP?

A

The LAP dedicates its radios to spectrum analysis on all wireless channels and can be remotely connected to software like MetaGeek Chanalyzer or Cisco Spectrum-Expert.

23
Q

What is the Cisco architecture that keeps the radios distributed, but collapses wireless services into the core of the switched network?

A

CUWN (Cisco Unified Wireless Network)

Cisco 200-355 (19 decks)
