Which type of IPv6 addressing allows for a one-to-closest address for IP services?
- A.Multicast address
- B.Anycast address
- C.Unicast address
- D.Loopback address
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
| A one-to-closest IPv6 address is an anycast address. Many routers or services can have the same address. However, routing protocols allow for the client to be directed to the closest resource. |

What type of address is ::1/128?
- A.Multicast address
- B.Anycast address
- C.Unicast address
- D.Loopback address
- Answer & Explanation
- Report
Answer : [D]
Explanation :
Explanation :
| The ::1 address is a special address called a loopback address, similar to 127.0.0.1 in IPv4. |

Which type of IPv6 addressing allows for a one-to-many address for IP services?
- A.Multicast address
- B.Anycast address
- C.Unicast address
- D.Loopback address
- Answer & Explanation
- Report
Answer : [A]
Explanation :
Explanation :
| A one-to-many IPv6 address is a multicast address. One multicast address will allow many IPv6 clients to receive the transmission. |
9.
Which command would you use to find the joined multicast groups for an IPv6
interface?
- A.Router# show ipv6 multicast
- B.Router# show ipv6 interface gi 0/1
- C.Router# show ipv6 routes
- D.Router# show mutlicast
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
| The output of show ipv6 interface gi 0/1 shows the multicast groups theinterface has joined. |

You are using the EUI-64 method of allocating the host portion of the IPv6
addresses. The MAC address of the host is e5ee:f556:2434. What is the correct IP
address that will be calculated for a network ID of fd00:2:2::?
- A.fd00:2:2::e9ee:f5ff:fe56:2434/64
- B.fd00:2:2::fffe:e5ee:f556:2434/64
- C.fd00:2:2::e7ee:f5ff:fe56:2434/64
- D.fd00:2:2::e2ee:f5ff:fe56:2434/64
- Answer & Explanation
- Report
Answer : [C]
Explanation :
Explanation :
| When converting a MAC address to an EUI-64 host address, the first step is to split the MAC address into 6-byte sections of e5eef5 and 562434 and place fffe in between them: e5ee:f5ff:fe56:2434. This gives you a 64-bit value comprised of a 48-bit MAC address and a 16-bit filler. You must then invert “flip” the 7th bit. Example: e5 = 1110 011 = flipped = 1110 0111 = e7. |
