Question 3
When troubleshooting a network, the output of the command show interfaces indicates a large number of runts. What is a runt?
A. the number of packets that are discarded because they exceed the maximum packet size of the medium
B. errors created when the CRC generated by the originating LAN station or far-end device does not match the checksum calculated from the data received.
C. the number of packets that are discarded because they are smaller than the minimum packet size of the medium
D. the number of received packets that were ignored by the interface because the interface hardware ran low on internal buffers
E. the number of times that the interface requested another interface within the router to slow down
Answer: C
Explanation
A runt is a packet that fails to meet the minimum size standard (below 64 bytes for Ethernet packet). Network protocols such as Ethernet often require that packets be a minimum number of bytes in order to travel the network. Runts are often the result of packet collisions along a busy network or can result from faulty hardware that is forming the packets or from corrupted data being sent across the network.
