Question

Which two fields in an Ethernet frame help synchronize device communica- tions but are not counted toward the frame’s size?

Answer 1

Preamble and SFD (start frame delimiter) fields help synchronize device communication but are not counted toward the frame's size.

Step-by-step explanation:

Preamble is a seven byte (56 bits) field which is first field in Ethernet frame followed by SFD (start frame delimiter) which is 1 byte (8bits) long field it marks the end of preamble field and start of Ethernet frame and supports byte level synchronization.
