20741 MOD3 IPv6

You are to convert the following IPv6 address from binary to hexadecimal. Then, simplify the hexadecimal address by using zero compression.
Binary IPv6 address:

0010 0000 0000 0001 0000 1101 0001 0001 0010 0010 0011 0100 0000 0000 0000 0000

0000 0011 1011 1011 0000 0000 1010 1100 1011 1100 0011 1011 1010 1101 0110 1011

a)    IPv6 address in hexadecimal format:
b) IPv6 address simplified by using zero compression: 

• 2001:d11:2234::3bb:0:acbc:3ba8

• 2001:d11:2234::3bb:0:acbc:3ba5

• 2001:d11:2234::3bb:0:acbc:3ba7

• 2001:d11:2234::3bb:0:acbc:3ba6

Answer explanation

The IPv6 address in hexadecimal format is 2001:d11:2234::3bb:0:acbc:3ba6. Zero compression simplifies the address by removing consecutive groups of zeros.

The main difference between 6to4 and Teredo is that while both protocols allow IPv6 connectivity over the IPv4 internet, only Teredo can provide connectivity through NAT.

• True

• False

How can you provide a DNS server to an IPv6 host dynamically?

• Configure DHCPv6

• Use IPv4 DNS server for an IPv6 host
• Use DHCPv4 to assign a DNS server to an IPv6 host
• Manually configure the DNS server on the host

To manage IPv6 with IPAM, you must enable IPv6 on the IPAM server.

• True

• False

What is the primary purpose of using IPv6 over IPv4?

• To reduce the size of the routing tables

• To increase the size of the address space

• To simplify the address configuration

• To improve the security features inherently

Which of the following is a feature of Dual Stack technology in IPv6 transition?

• It translates IPv6 packets into IPv4 packets

• It encapsulates IPv6 packets within IPv4 packets

• It allows IPv6 and IPv4 to coexist on the same network interface

• It assigns both IPv4 and IPv6 addresses to hosts

Which protocol is used by IPv6 to discover the hardware address of a node on the same local link?

• ARP

• ICMPv6

• DHCPv6

• RARP

What mechanism does IPv6 use to ensure that a packet is delivered to its intended destination only once?

• Flow Label

• Sequence Number

• Fragment Offset

• Hop Limit

Which IPv6 feature eliminates the need for NAT (Network Address Translation)?

• Autoconfiguration

• Stateless address autoconfiguration (SLAAC)

• Large address space

• Integrated security features

In IPv6, what is the purpose of the Neighbor Discovery Protocol (NDP)?

• To replace the ARP protocol used in IPv4

• To discover other IPv6 hosts on the same network segment

• To provide automatic IP address configuration

• All of the above
