IPv6

Given a /48 global routing prefix and a /64 prefix, what is the subnet portion of the address 2001:db8:cafe:1111:2222:3333:4444:5555?

1111

Given a /32 global routing prefix and a /64 prefix, how many bits would be allocated for the subnet ID?

32

What are the two methods a device can use to generate its own IPv6 interface ID? (choose 2)

EUI-64 , random generation

t/f Tunneling allows IPv6-enabled devices to communication wtih IPv4-enabled devices using a technique similar to NAT for IPv4

False

Say that the network administrator allotted your section of the network four /64 IPv6 subnets, starting with the subnet address space 2001:db8:cafe:aa9f::/64. What would be the next three /64 subnets?

First subnet: → 2001:db8:cafe:aaa0::/64 Second subnet: → 2001:db8:cafe:aaa1::/64 Third subnet → 2001:db8:cafe:aaa2::/64

Which dynamic addressing method for GUAs is the one where devices rely solely on the contents of the RA message for their addressing information?

Method 1: SLAAC

Which dynamic addressing method for GUAs is the one where devices rely solely on a DHCPv6 server for their addressing information?

Method 3: Stateful DHCPv6

t/f IPv6 global unicast addresses (GUAs) are globally unique and routable on the IPv6 Internet.

True

t/f IPv6 was designed with subnetting in mind.

True

Match each description with the appropriate type of IPv6 address.

Typical IPv6 prefix used to indicate the network portion of the address → /64 Unique, internet-routable IPv6 address (dynamic or static) → global unicast Used to communicate with other devices only on the same IPv6 subnet → link local IPv6 address represented as ::1/128 (compressed format) → loopback IPv6 address in the range FC00::/7 to FDFF::/7 → unique local

What is the most important motivating factor for moving to IPv6?

depletion of IPv4 addresses

Which of the following techniques uses native IPv6 connectivity?

dual stack

Which field in an IPv6 GUA is used for subnetting?

subnet ID
