Resource summary

Question 1

Question
Looking at the following IPv6 adresses: 2001:cdba:0000:0000:0000:0000:3257:9652 2001:cdba:0:0:0:0:3257:9652 2001:cdba::3257:9652
Answer
  • All look similar but refer to different hosts.
  • The addresses are all valid and equivalent
  • the addresses are all invalid
  • only the last address in the list is valid

Question 2

Question
Check the items in the list that are considered optional headers used with IPv6
Answer
  • Hop by Hop options header
  • Destination options header
  • Routing Header
  • Fragmented header
  • Authentication header (AH)
  • Encapsulation security payload (ESP) header

Question 3

Question
In the command ipv6 address 2001:ffff:2::/64 eui-64
Answer
  • Configures the IPv6 address for the interface and enable IPv6 processing on the interface using an EUI-64 interface ID in the high order 64 bits of the address.
  • Configures the IPv6 address for the interface and enable IPv6 processing on the interface using an EUI-64 interface ID in the low order 64 bits of the address. This basically allows the router to work out the host portion of the address from the interface MAC address
  • Configures the IPv6 address using an EUI-64 interface ID as the high order 64 bits of the address with the remaining bits being calculated using the 4to6 algorithm.
  • Configures the IPv6 address for the interface and converts the 48- bit MAC address to a EUI-64 address.

Question 4

Question
What is stateless autoconfiguration of hosts?
Answer
  • IPv6 hosts can be configured automatically when connected to a routed IPv6 network from a DHCP server exactly like with IPv4.
  • IPv6 hosts can be configured automatically when connected to a routed IPv6 network by the addition of a stateless IPv6 address configuration server.
  • IPv6 hosts can be configured automatically when connected to a routed IPv6 network,
  • IPv6 hosts can be configured at the factory for all IPv6 networks.

Question 5

Question
The Duplicate Address Detection Algorithm is a Microsoft initiative to prevent users from configuring addresses that are already configured by users on the network. This results in a popup message to the user informing them of their error and the error code. 0x335467.
Answer
  • True
  • False

Question 6

Question
The major difference between OSPFv4 and OSPFv6 is that OSPFv6 added a security element.
Answer
  • True
  • False

Question 7

Question
In IPv4, packets are limited to 64KB of payload. When used between capable communication partners. IPv6 has support for packets over this limit, referred to as ______________. (not multiple choice)
Answer
  • Limitless Packets
  • Jumbograms
  • MAximgrams
  • Big UNs

Question 8

Question
The IPv6 interface is expected in EUI-64, however devices can still use the older 48-bit MAC address format.
Answer
  • Such devices cannot be used with IPv6
  • These can be converted to EUI-64 and then to modified EUI-64 form for calculating an IPv6 interface ID.
  • Such devices can be used with the addition of a 4to6 tunnel translator
  • The difference between 46 bits and 64 bits is just padded out zero's.

Question 9

Question
Addresses with the fe80::/12 prefix are:
Answer
  • Site-Local and auto-configured by hosts only if conected to a router
  • Site-Local and auto-configured by hosts despite being connected to a router or not
  • Site-Local and auto-configured by hosts only if connected to a router

Question 10

Question
The main feature of a IPv6 is the larger address space: addresses in IPv6 are ____ bits long
Answer
  • 64
  • 192
  • 128
  • 32
