Final answer:
Three scenarios in which a collision can occur in the broadcast domain are half-duplex Ethernet, network congestion, and port mirroring.
Step-by-step explanation:
In a broadcast domain, a collision can occur when two or more devices attempt to transmit data at the same time. Here are three scenarios that could lead to collisions:
- Half-duplex Ethernet: In a half-duplex Ethernet network, only one device can transmit at a time. If two devices try to transmit simultaneously, a collision occurs.
- Network congestion: When there is high network traffic and multiple devices are trying to access the same network resources, collisions can occur due to congestion.
- Port mirroring: Port mirroring is a technique used for monitoring network traffic by duplicating incoming and outgoing packets. If multiple devices are mirroring the same port and sending data simultaneously, collisions can occur.
