Question:
Refer to the exhibit. A network technician is troubleshooting connectivity issues in an Ethernet network with the command show interfaces fastEthernet 0/0. What conclusion can be drawn based on the partial output in the exhibit?

• All hosts on this network communicate in full-duplex mode.
• Some workstations might use an incorrect cabling type to connect to the network.
• There are collisions in the network that cause frames to occur that are less than 64 bytes in length.
• A malfunctioning NIC can cause frames to be transmitted that are longer than the allowed maximum length.

Explanation: The partial output shows that there are 50 giants (frames longer than the allowed maximum) that were injected into the network, possibly by a malfunctioning NIC. This conclusion can be drawn because there are only 25 collisions, so not all the 50 giants are the result of a collision. Also, because there 25 collisions, it is most likely that not all hosts are using full-duplex mode (otherwise there would not be any collisions). There should be no cabling issues since the CRC error value is 0. There are 0 runts, so the collisions have not caused malformed frames to occur that are shorter than 64 bytes in length .
