B) DHCPv6 servers provide link-local addresses. C) DHCPv6 servers provide the other half of the IPv6 address. D) There is no such thing as a DHCPv6 server.

A

What is a valid IPv6 prefix length? A) /64 B) /72 C) /255 D) 255.255.255.0

A

What is the only type of IPv6 address required to communicate with other computers on a local network? A) Link-local B) Global unicast C) EUI-64 D) Multicast

A

What is true of current global addresses? A) They always begin with 2001::, 2002::, 2003::, and so on. B) They always begin with FF02::1, FF02::2, FF03::3, and so on. C) They are only 64 bits long. D) They are only used by root and tier-one routers.

A

What type of address applies to a single unique network node? A) Unicast B) Unilateral C) Multicast D) Omnicast

A

Which of the following IPv6 addresses are equivalent to ACCB:0876:0000:0000:FD87:0000:0000:0064? (Select two.) A) ACCB:876::FD87:0:0:64 B) ACCB:876::FD87::64 C) ACCB:876:0:0:FD87::64 D) ACCB:876:0:FD87:0:64

A and C

How do IPv6 multicasts differ from broadcasts? A) Broadcasts are sent to all network nodes. Multicasts are sent only to specific network nodes. B) Both broadcasts and multicasts are sent to all network nodes, but in a multicast, only the destination nodes read the incoming packets. C) Broadcasts can cross over a router, whereas multicasts cannot. D) Broadcasts are used on local networks; multicasts are used on the Internet.

B

Which of the following is a valid IPv6 address? A) 192.168.0.1 B) 2001:376:BDS:0:3378:BAAF:QR9:223 C) 2541:FDC::ACDF:2770:23 D) 0000:0000:0000:0000:0000:0000:0000:0000

B

B

Which protocol enables 6to4 tunneling in Linux? A) GOGO B) Miredo C) Teredo D) 6to4En

B

A packet has been sent to the address FF02:0000:0000:0002:0BCD:23DD:3456:0001. What will read the sent packet? A) The single computer with the address FF02:0000:0000:0002:0BCD:23DD:3456:0001. B) Every network node. C) Every router on the network. D) Nothing will read the packet because it is an invalid address.

C

What is the main benefit of IPv6 aggregation? A) It allows users to combine multiple IPv6 addresses to increase their bandwidth and overall Internet speed exponentially. B) It is backward-compatible and can be directly applied to IPv4 networks. C) It reduces the size and complexity of routing tables, allowing routers to work more efficiently. D) Signals are increased with each router the packet travels through, allowing for greater distances over wireless networks.

C

What is true of link-local addresses? A) They are passed out by the default gateway router. B) They are completely randomly generated by each computer. C) All modern operating systems (post Windows XP) generate the second 64-bit portion randomly. D) They always start with 169.254.

C
