Exam 200-301 topic 1 question 4 discussion

input errors: total of many counters, including all below frame: Frames on illegal format. Can be caused by collisions giants: Frames that exceeded the maximum size (1518 bytes) CRC: Received frames that did not pass the FCS math runts: Frames that did not meet the minimum size (64 bytes). Can be caused by collisions Therefore CRC and INPUT ERRORS will be increased.

A,D is correct.

When a frame enters a switch and fails the Frame Check Sequence (FCS), it means that the integrity of the frame has been compromised, usually due to data corruption during transmission. The FCS is a checksum value included in the frame to detect errors. If the calculated FCS does not match the one in the frame, the switch will discard the frame to prevent forwarding potentially corrupted data. A CRC (Cyclic Redundancy Check) error occurs when the FCS does not match the calculated value, indicating data corruption in the frame. The CRC counter specifically tracks these types of errors, which happen when the FCS mismatch occurs.

B. frame Wrong answer. C. giants Wrong answer. D. CRC Correct answer. E. runts Wrong answer.

Explanation When a frame fails the Frame Check Sequence (FCS), it indicates that there has been a data transmission error. This typically increments the input errors counter and the Cyclic Redundancy Check (CRC) counter on the interface of the switch where the frame was received. The input errors counter is incremented for any errors at the input, and the CRC counter specifically tracks errors detected by the FCS.
