Question 61

Which Ethernet frame field does the receiver use to verify the integrity of the received bits?

  1. Destination address
  2. Frame check sequence
  3. Preamble
  4. Length field

Question 62

How is Ethernet II different from Ethernet 802.3?

  1. Ethernet 802.3 can only be used on point-to-point links, while Ethernet II can be used on broadcast networks.
  2. In Ethernet II the 2 bytes after the source MAC address is used as a type indicator. In Ethernet 802.3 these two bytes indicate the length of the frame.
  3. In Ethernet 802.3, the 2 bytes after the source MAC address is used as a type indicator. In Ethernet II these two bytes indicate the length of the frame.
  4. Ethernet II and Ethernet 802.3 are two different names for the same protocol

  2. Multicast.
  3. Broadcast.
  4. Unicast.

Question 65

Which of the following is true of Ethernet half-duplex transmission?

  1. Half-duplex transmission is less efficient because the frame MTU is smaller.
