Q

the three organizations influencing WLAN standards are:?

A
  • ITU-R - Regulates the allocation of the RF spectrum and satellite orbits.
  • IEEE - Specifies how RF is modulated to carry information. It maintains the standards for local and metropolitan area networks (MAN
  • Wi-Fi Alliance -The Wi-Fi Alliance® (http://www.wi-fi.org) is a global, non-profit, industry trade association devoted to promoting the growth and acceptance of WLAN

16
Q

what is an Autonomous Access point?

A

each wireless access point has to be configured manually. often used in small networks. each AP operated separate/ independent from the others.

17
Q

what is clustering of access points?

A

The cluster provides a single point of administration and enables the administrator to view the deployment of APs as a single wireless network, rather than a series of separate wireless devices

18
Q

SPS?

A

Single Point Setup (SPS). used when clustering wireless access points together.

19
Q

what conditions must be met between wireless access points for a cluster to form?

A

clustering enabled on both devices, same cluster name, connected on same network segment and same radio mode is used on each device. (like 802.11n)

20
Q

Cisco Meraki Cloud Managed Architecture?

A

management solution used to simplify the wireless deployment. Using this architecture, APs are managed centrally from a controller in the cloud.
MCC is a cloud-based service that constantly monitors, optimizes, and reports the behavior of the network
