A small business is using Radio Frequency (RF) planning to establish and limit the number of
access points (APs) needed for a coverage area. The company is trying to decide what to use for
the baseline association rate for clients to connect to the access points.
Which two statements are correct? (Choose two.)
A. A baseline association rate of 54 Mbps requires more APs than a baseline association rate of
B. A baseline association rate of 18 Mbps requires more APs than a baseline association rate of
C. A baseline association rate of 54 Mbps requires the client to be farther away from the AP to
reach the targeted rate.
D. A baseline association rate of 18 Mbps requires the client to be farther away from the AP to
reach the targeted rate.
You are using the RF Planning tool in RingMaster to configure a data capacity plan for a client.
Which three settings are required on the Data Capacity Options page? (Choose three.)
A. AP authentication mode
B. Per Station Throughput
C. Expected Station Count
D. Coverage Area
E. Station Oversubscription Ratio
Multiple users are complaining that their wireless connections are not working.
Which RingMaster screen would the administrator use for troubleshooting?
A network administrator must perform a software upgrade of a factory-default wireless LAN
controller (WLC) using the CLI.
Which three actions are required? (Choose three.)
A. Set the inactive boot partition to the active boot partition.
B. Add an upgraded license for the new image.
C. Copy the new image to the inactive boot partition using TFTP.
D. Reboot the controller.
E. Upgrade the connected access points (APs) before upgrading the controller.
