CCNA: Cisco Certified Network Associate — Question 224

A frame that enters a switch fails the Frame Check Sequence. Which two interface counters are incremented? (Choose two.)

Answer options

• A. input errors
• B. frame
• C. giants
• D. CRC
• E. runts

Correct answer: A, D

Explanation

When a frame fails the Frame Check Sequence, it indicates corruption during transmission, leading to an increase in 'input errors'. Additionally, 'CRC' (Cyclic Redundancy Check) errors are specifically related to the integrity check failing, thus also incrementing. The other options, such as 'frame', 'giants', and 'runts', do not directly correlate with Frame Check Sequence failures.
