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
Respuesta
-
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

Pregunta 3
Pregunta
In the command ipv6 address 2001:ffff:2::/64 eui-64
Respuesta
-
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.
Pregunta 4
Pregunta
What is stateless autoconfiguration of hosts?
Respuesta
-
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.
Pregunta 5
Pregunta
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.
Pregunta 6
Pregunta
The major difference between OSPFv4 and OSPFv6 is that OSPFv6 added a security element.
Pregunta 7
Pregunta
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)
Respuesta
-
Limitless Packets
-
Jumbograms
-
MAximgrams
-
Big UNs
Pregunta 8
Pregunta
The IPv6 interface is expected in EUI-64, however devices can still use the older 48-bit MAC address format.
Respuesta
-
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.
Pregunta 9
Pregunta
Addresses with the fe80::/12 prefix are:
Respuesta
-
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
