Correct Answer: Corrupted data packets due to physical layer problems (e.g., bad cabling, signal integrity issues) Explanation: CRC errors occur when the data received does not match the checksum calculated by the transmitting device, almost always indicating a physical layer issue such as a bad cable, faulty port, or electromagnetic interference.
