A frame that enters a switch fails the Frame Check Sequence. Which two interface counters are incremented? (Choose two.)
A frame that enters a switch fails the Frame Check Sequence. Which two interface counters are incremented? (Choose two.)
When a frame enters a switch and fails the Frame Check Sequence (FCS), it indicates that the frame has encountered an error during transmission. This type of error is detected through the Cyclic Redundancy Check (CRC) process. As a result, two specific interface counters are incremented. The 'input errors' counter is incremented because it tallies all incoming errors, including CRC errors, giants, runts, and other types of errors. Simultaneously, the 'CRC' counter is incremented since it specifically logs the number of frames that failed the CRC check. These increments help network administrators identify and troubleshoot issues related to data transmission errors.
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.

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.
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.
Input Errors – This counter tracks errors in incoming frames, including CRC errors and other physical layer issues. CRC – A CRC (Cyclic Redundancy Check) error indicates that the frame has failed the FCS validation.
