Quiz 6C: Explain IPv6 Addressing Schemes

What problem does IPv6 address space aim to solve?

• Congestion in network traffic

• Address exhaustion in IPv4

• Security vulnerabilities in TCP/IP

• DNS resolution latency

How many unique addresses can IPv6 accommodate?

• 4 billion

• 232

• 340 undecillion

• 128

What is the purpose of the Traffic Class field in an IPv6 packet header?

• Identifying the packet's priority

• Indicating the length of the packet payload

• Describing the payload format

• Managing quality of service (QoS)

Which protocol replaces ARP in IPv6 for address resolution?

• ICMPv6

• DHCPv6

• MLD

• ND

How are IPv6 multicast addresses indicated?

• With a prefix starting with 2000::

• With a prefix starting with ff00::

• With a prefix starting with fe80::

• With a prefix starting with 2 or 3

What is the significance of the first 3 bits in an IPv6 global address?

• Indicates the length of the network prefix

• Identifies the interface ID

• Specifies the scope of the address

• Signifies the version of the IP protocol

How is a link-local IPv6 address formed?

• By concatenating the MAC address with a prefix

• By appending the interface ID to the network prefix

• By generating a random 64-bit value

• By assigning the next available address in the subnet

What is the function of the Flow Label field in an IPv6 packet header?

• Describes the packet's priority

• Used for QoS management

• Indicates the length of the packet payload

• Specifies the next header

How are IPv6 addresses compressed using double colon notation?

• By replacing contiguous series of zeros with a double colon

• By adding leading zeros to each double byte

• By using a double colon for each zero in the address

• By removing leading zeros from each double byte

What is the main difference between stateless and stateful address autoconfiguration in IPv6?

• Stateless autoconfiguration requires DHCPv6, while stateful autoconfiguration does not.

• Stateful autoconfiguration uses ICMPv6, while stateless autoconfiguration does not.

• Stateless autoconfiguration requires manual configuration, while stateful autoconfiguration is automatic.

• Stateful autoconfiguration involves obtaining additional configuration information from a DHCPv6 server.
