  • there are 40 bytes of options
  • there are 10 bytes in the header
  • there are 40 bytes in the header

3. In IPv4, what is the value of the total length field in bytes if the header is 28 bytes and the data field is 400 bytes?

  • 428
  • 407
  • 107

5. An IPv4 datagram is fragmented into three smaller datagrams. Which of the following is true?

  • The more fragment bit is set to 0 for all three datagrams
  • The identification field is the same for all three datagrams.
  • The offset field is the same for all three datagrams

6. In IPv4, if the fragment offset has a value of 100, it means that _______

  • Offset number
  • Total length
  • (b) and (c)

8. The IPv4 header size _______

  • is 20 to 60 bytes long
  • is always 20 bytes long
  • is always 60 bytes long
  • depends on the MTU

9. Which of the following is a necessary part of the IPv6 datagram?

  • (a) and (c)

10. In IPv6, the _______ field in the base header restricts the lifetime of a datagram

  • version
  • next-header
  • hop limit
  • neighbor-advertisement

11. The ________ protocol is the transmission mechanism used by the TCP/IP suite.

  • a connectionless
  • both a and b
  • none of the above

13. The term ________ means that IP provides no error checking or tracking. IP assumes the unreliability of the underlying layers and does its best to get a transmission through to its destination, but with no guarantees.

  • reliable delivery
