Dell EMC Associate – Midrange Storage — Question 10

Which field of the 802.3 frame is used by network interface cards to synchronize their receivers?

Answer options

• A. Start frame delimiter
• B. Preamble
• C. Cyclic redundancy check
• D. Frame check sequence

Correct answer: B

Explanation

The Preamble is utilized by network interface cards for synchronization of their receivers because it provides a signal to indicate the start of a frame. The Start frame delimiter marks the beginning of the frame but does not assist in synchronization. The Cyclic redundancy check and Frame check sequence are used for error checking and integrity verification, not for synchronization.
