A small publishing company has a network design such that when a broadcast is sent on the LAN, 200 devices receive the transmitted broadcast. How can the network administrator reduce the number of devices that receive broadcast traffic?

Replace at least half of the switches with hubs to reduce the size of the broadcast domain.

Add more switches so that fewer devices are on a particular switch.

Segment the LAN into smaller LANs and route between them.

Replace the switches with switches that have more ports per switch. This will allow more devices on a particular switch.

Segment the LAN into smaller LANs and route between them.

How can you eliminate collisions on an Ethernet network?

Since 1990, the way to avoid collisions in an Ethernet is to use an Ethernet switch. The switch accepts a frame from an attached device, even while receiving frames from other devices and while transmitting to devices. When the destination port becomes non-busy, the switch sends it out to the destination.

How is a collision determined on an Ethernet network?

Ethernet uses Carrier Sense Multiple Access/ Collision Detect (CSMA/CD) as its method of allowing devices to "take turns" using the signal carrier line. When a device wants to transmit, it checks the signal level of the line to determine whether someone else is already using it.

What causes collisions on network?

A network collision occurs when two devices attempt to transmit data on a shared circuit. In a shared circuit where multiple devices are listening, only a single device can transmit data at a single point in time which requires the rest of the devices to be listening to the transmission.

Which solution would help a college alleviate network congestion due to collision?

Which solution would help a college alleviate network congestion due to collisions? Switches provide microsegmentation so that one device does not compete for the same Ethernet network bandwidth with another network device, thus practically eliminating collisions.
