Question 1

[am4show have=’p2;’]Which command enables IPv6 forwarding on a Cisco router?

A. ipv6 local
B. ipv6 host
C. ipv6 unicast-routing
D. ipv6 neighbor

 

Answer: C[/am4show]

Explanation

An example of configuring RIPng (similar to RIPv2 but is used for IPv6) is shown below:

Router(config)#ipv6 unicast-routing (Enables the forwarding of IPv6 unicast datagrams globally on the router)
Router(config)#interface fa0/0
Router(config-if)#ipv6 rip 9tut enable (9tut is the process name of this RIPng)

Question 2

[am4show have=’p2;’]The network administrator has been asked to give reasons for moving from IPv4 to IPv6. What are two valid reasons for adopting IPv6 over IPv4? (Choose two)

A. telnet access does not require a password
B. nat
C. no broadcast
D. change of destination address in the IPv6 header
E. change of source address in the IPv6 header
F. autoconfiguration

 

Answer: C F[/am4show]

Explanation

With IPv6, devices can build a link-local address automatically. But notice this address is only used for communications within the local subnetwork, routers do not forward these addresses.

Question 3

[am4show have=’p2;’]Which of these represents an IPv6 link-local address?

A. FE08::280e:611:a:f14f.3d69
B. FE81::280f.512b:e14f:3d69
C. FE80::380e:611a:e14f:3d69
D. FEFE:0345:5f1b::e14d:3d69

 

Answer: C[/am4show]

Explanation

The range of IPv6 link-local address (similar to the Windows auto-configuration IP address of 169.254.x.x.) is FE80::/10. For more information about IPv6, please read my IPv6 tutorial.

Question 4

[am4show have=’p2;’]Which three approaches can be used while migrating from an IPv4 addressing scheme to an IPv6 scheme? (Choose three)

A. enable dual-stack routing
B. configure IPv6 directly
C. configure IPv4 tunnels between IPv6 islands
D. use proxying and translation to translate IPv6 packets into IPv4 packets
E. statically map IPv4 addresses to IPv6 addresses
F. use DHCPv6 to map IPv4 addresses to IPv6 addresses

 

Answer: A C D[/am4show]
