Which device does a network engineer use to break the network environment into smaller collision domains?
The correct answer is A. switch. A switch creates a separate collision domain per port. When a frame arrives on one port, only that port (and the destination port) is involved - other ports are unaffected. This is fundamentally different from a hub, which places all connected devices in the same collision…

Explanation
A switch creates a separate collision domain per port. When a frame arrives on one port, only that port (and the destination port) is involved - other ports are unaffected. This is fundamentally different from a hub, which places all connected devices in the same collision domain, forcing them to share bandwidth and take turns transmitting. A router breaks up broadcast domains (not collision domains). Repeaters and hubs extend or regenerate signals but do not segment collision domains. CSU/DSUs are WAN interface devices unrelated to collision domain segmentation.
