Answer: A

Explanation:

A network topology that is set up so that each device is directly connected to every other
device on the network. This connection method has built-in redundancy. If one link goes
down, the device will transmit via another link.

Example:
If the partial mesh design is a compromise between the network administrators and
managers, then the full mesh design implies that the network administrators won. This
design is every Cisco network administrator's picture of perfection over a Frame Relay
cloud. It gives every site a direct virtual circuit to every other site, as shown in Figure
This design gives maximum redundancy and minimum packet latency (latency describes
how long it takes a packet to reach each location).
