Your boss is interested in a wireless WAN solution which provides higher bandwidth than point-to- multipoint (p2mp) wireless. Which description is correct?
A.
Service providers cannot install point-to-point (p2p) links from a p2mp hub.
B.
P2p wireless connections can provide up to 44 Mbps raw bandwidth.
C.
P2p links tend to be slower than p2mp.
D.
P2mp wireless connections can provide up to 1.544 Mbps raw bandwidth.

Book answer matches posted answer, although they don’t go into how the bandwidth is calculated based on the PHY layer.

Option A is false:
“Some SMB customers will require a data rate that is higher than the service provider can supply within the traffic capacity of the multipoint system. The service provider may satisfy those customers by installing Cisco’s point-to-point (P2P) links from the same hub as the P2MP system. Thus, the hub can be a mixture of P2MP and P2P systems.”
Option C is false:
“Point-to-point – P2P; has a higher bandwidth than P2MP because, among other things, it has less overhead to manage the data paths and only one receiver exists per transmitter. Cisco offers MMDS, U-NII, and LMDS systems in P2P.”
