Final answer:
If the network is configured correctly, collisions should be zero, but errors may still occur.
Step-by-step explanation:
If the wireless mesh network is configured correctly, the error type that should be zero is collisions. Collisions occur when two or more devices attempt to transmit data at the same time on the same channel, causing interference and data loss. A well-configured network should have mechanisms in place, such as collision avoidance algorithms or routing protocols, to minimize or eliminate collisions.
On the other hand, errors can still occur even in a correctly configured network. These errors can be caused by external factors such as signal interference, environmental conditions, or hardware issues. However, a well-designed network will have error correction mechanisms in place, such as error detection algorithms and retransmission protocols, to minimize the impact of errors.
