Which of the following is the primary method for transmitting IPv6 traffic over an IPv4
network?
- A.Subnetting
- B.Tunneling
- C.Supernetting
- D.Contracting
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
A. Incorrect: Subnetting is a technique for creating administrative divisions on
a network; it does not transmit IPv6 traffic over an IPv4 network. B. Correct: Tunneling is a method for encapsulating IPv6 traffic within IPv4 datagrams. C. Incorrect: Supernetting is a method for combining consecutive subnets into a single entity. D. Incorrect: Contracting is a method for shortening IPv6 addresses. |

Which of the following is the IPv6 equivalent to a private IPv4 address?
- A.Link-local unicast address
- B.Global unique unicast address
- C.Unique local unicast address
- D.Anycast address
- Answer & Explanation
- Report
Answer : [C]
Explanation :
Explanation :
A. Incorrect: Link-local unicast addresses are self-assigned by IPv6 systems. They are
therefore the equivalent of APIPA addresses on IPv4. B. Incorrect: A global unicast address is the equivalent of a registered IPv4 address, routable worldwide and unique on the Internet. C. Correct: Unique local unicast addresses are the IPv6 equivalent of the 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 private network addresses in IPv4. D. Incorrect: The function of an anycast address is to identify the routers within a given address scope and send traffic to the nearest router. |

Which of the following is an automatic tunneling protocol used by Windows operating
systems that are located behind NAT routers?
- A.Teredo
- B.6to4
- C.ISATAP
- D.APIPA
- Answer & Explanation
- Report
Answer : [A]
Explanation :
Explanation :
A. Correct: Teredo is a mechanism that enables devices behind non-IPv6 NAT routers
to function as tunnel endpoints. B. Incorrect: 6to4 incorporates the IPv4 connections in a network into the IPv6 infrastructure by defining a method for expressing IPv4 addresses in IPv6 format and encapsulating IPv6 traffic into IPv4 packets. C. Incorrect: Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) is an automatic tunneling protocol used by the Windows workstation operating systems that emulates an IPv6 link using an IPv4 network. D. Incorrect: APIPA is an automatic IPv4 address self-assignment process. It has nothing to do with tunneling. |

- A.Registered
- B.Binary
- C.Class B
- D.Subnetted
- Answer & Explanation
- Report
Answer : [A]
Explanation :
Explanation :
A. Correct: For an address to be visible from the Internet, it must be registered
with the IANA. B. Incorrect: Binary is a system of numbering that can be used to express any IP address. C. Incorrect: All address classes can be visible or invisible to the Internet. D. Incorrect: Subnetted addresses can be visible or invisible to the Internet. |

client with an IPv4 address on the 172.16.32.0/19 network?
- A.255.224.0.0
- B.255.240.0.0
- C.255.255.224.0
- D.255.255.240.0
- E.255.255.255.240
- Answer & Explanation
- Report
Answer : [C]
Explanation :
Explanation :
A. Incorrect: In binary form, the mask 255.224.0.0 is 11111111.11100000.00000000.
00000000, which contains only 11 network identifier bits. B. Incorrect: In binary form, the mask 255.240.0.0 is 11111111.11110000.00000000. 00000000, which contains only 12 network identifier bits. C. Correct: In binary form, the mask 255.255.224.0 is 11111111.11111111.11100000. 00000000, which contains 19 network identifier bits. D. Incorrect: In binary form, the mask 255.255.240.0 is 11111111.11111111.11110000. 00000000, which contains 20 network identifier bits. E. Incorrect: In binary form, the mask 255.255.255.240 is 11111111.11111111. 11111111.11110000, which contains 28 network identifier bits. |
