CCNA Question of the Week

Device A is sending data to Device B. In what order does Device A encapsulate the data in the various protocol data units (PDUs)?

  1. Data into Segment into Packet into Frame into Bits
  2. Data into Packet into Segment into Frame into Bits
  3. Data into Bits into Frame into Packet into Segment
  4. Data into Frame into Packet into Segment into Bits

The correct answer is A.

During communication, devices encapsulate PDUs from upper layers. Data is put into a Segment, which is put into a Packet, which is put into a Frame, which is sent out in Bits.
