Section 4 – Implement an IPv6 based solution, given a network design and a set of requirements
QUESTION NO: 6
During the IPv6 autoconfiguration, what does the device append to the 64-bit prefix that it receives from the router to create its IPv6 address? Select the best response.
A. a pseudorandom generated number
B. its locally configured IPv4 address
C. the DHCP-supplied device ID
D. its MAC address
QUESTION NO: 7
What will occur when an IPv6 enabled router running 6to4 must transmit a packet to a remote destination and the next hop is the address of 2002::/16 ?
A.The IPv6 packet has its header removed and replaced with an IPv4 header
B.The IPv6 packet is encapsulated in an IPv4 packet using an IPv4 protocol type of 41
C.The IPv6 packet is dropped because that destination is unable to route IPv6 packets
D.The packet is tagged with an IPv6 header and the IPv6 prefix is included
QUESTION NO: 8
Which three are characteristics of IPv6? (Choose three.) Select 3 response(s).
A. An IPv6 address is 128 bits long.
B. An IPv6 header is 20 bits long.
C. An IPv6 header contains the next header field.
D. An IPv6 header contains the protocol field.
E. IPv6 routers send RA messages.
F. An IPv6 header contains the header checksum field.
All IPv6 addresses are 128 bits long to accommodate a far larger number of stations than what was possible with the 32 bit IPv4 addresses.
The following displays the IPv6 header field in detail:
Version . 4 bits. IPv6 version number.
Traffic Class . 8 bits. Internet traffic priority delivery value.
Flow Label . 20 bits. Used for specifying special router handling from source to destination(s) for a sequence of packets.
Payload Length . 16 bits unsigned. Specifies the length of the data in the packet. When cleared to zero, the option is a hop-by-hop Jumbo payload.
Next Header . 8 bits. Specifies the next encapsulated protocol. The values are compatible with those specified for the IPv4 protocol field.
Hop Limit . 8 bits unsigned. For each router that forwards the packet, the hop limit is decremented by 1. When the hop limit field reaches zero, the packet is discarded. This replaces the TTL field in the IPv4 header that was originally intended to be used as a time based hop limit.
Source address . 16 bytes. The IPv6 address of the sending node.
Destination address . 16 bytes. The IPv6 address of the destination node.
QUESTION NO: 9
Using the rules for IPv6 addressing, how can the address 2031:0000:240F:0000:0000:09C0:123A:121B be rewritten? Select the best response.
QUESTION NO: 10
What number is a valid representation for the
200F:0000:AB00:0000:0000:0000:0000/56 IPv6 prefix?
