What two statements about IPv4 and IPv6 addresses are true?
- A.An IPv6 address is 32 bits long, represented in hexidecimal.
- B.An IPv6 address is 128 bits long, represented in decimal.
- C.An IPv4 address is 32 bits long, represented in decimal.
- D.An IPv6 address is 128 bits long, represented in hexidecimal.
- Answer & Explanation

Answer : [C, D]
Explanation :
Explanation :
| IPv4 addresses are 32 bits long and are represented in decimal format. IPv6 addresses are 128 bits long and represented in hexadecimal format. |

What two statements about IPv6 addresses are true? (Choose two.)
- A.Leading zeros are required.
- B.Two colons (::) are used to represent successive hexadecimal fields of zeros.
- C.Two colons (::) are used to separate fields.
- D.A single interface will have multiple IPv6 addresses of different types.
- Answer & Explanation

Answer : [B, D]
Explanation :
Explanation :
| In order to shorten the written length of an IPv6 address, successive fields of zeros may be replaced by double colons. In trying to shorten the address further, leading zeros may also be removed. Just as with IPv4, a single device's interface can have more than one address; with IPv6 there are more types of addresses and the same rule applies. There can be link-local, global unicast, and multicast addresses all assigned to the same interface. |

Which WAN encapsulations can be configured on an asynchronous serial connection?
(Choose two.)
- A.Router1(config-if)# ipv6 ospf 10 area 0.0.0.0
- B.Router1(config-if)#ipv6 router rip 1
- C.Router1(config)# ipv6 router eigrp 10
- D.Router1(config-rtr)#no shutdown
- E.Router1(config-if)#ospf ipv6 10 area 0
- Answer & Explanation
- Report
Answer : [A]
Explanation :
Explanation :
| To enable OSPFv3, you enable the protocol as with RIPng. The command string is ipv6 ospf process-id area area-id. |

To enable EIGRP, which three of the following would you use?
- A.Router1(config-if)# ipv6 ospf 10 area 0.0.0.0
- B.Router1(config-if)#ipv6 router rip 1
- C.Router1(config)# ipv6 router eigrp 10
- D.Router1(config-rtr)#no shutdown
- E.Router1(config-if)#ipv6 eigrp 10
- Answer & Explanation
- Report
Answer : [C, D, E]
Explanation :
Explanation :
| Unlike RIPng and OSPFv3, you need to configure EIGRP both from global configuration mode and from interface mode, and you have to enable the command with the no shutdown command. |
75.
To enable RIPng, which of the following would you use?
- A.Router1(config-if)# ipv6 ospf 10 area 0.0.0.0
- B.Router1(config-if)#ipv6 router rip 1
- C.Router1(config)# ipv6 router eigrp 10
- D.Router1(config-rtr)#no shutdown
- E.Router1(config-if)#ipv6 eigrp 10
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
| It's pretty simple to enable RIPng for IPv6. You configure it right on the interface where you want RIP to run with the ipv6 router rip number command. |
