Question 7
An Ethernet frame is captured by network protocol analyzer tool and the value of Type/Length field is 0x0800.  
Which of the following statements about the frame are correct? (Choose two)

  • A: The frame structure of the frame is Ethernet_II
  • B: The frame structure of the frame is 802.3
  • C: Its upper layer protocol is IP
  • D: Its upper layer protocol is IPX
Correct Answer: AC



Question 8
Which of the following descriptions regarding the TTL field of the IP packet is correct?

  • A: The TTL defines how many packets the source can send.
  • B: The TTL defines the duration during which the source can send packets.
  • C: The TTL value will decrement by 1 each time the packet is routed.
