Question 1

An IPv6 ________ address is equivalent to an IPv4 public address.&#10;A) Global unicast&#10;B) Public multicast&#10;C) Public unicast&#10;D) Unique local

Accepted Answer

A) An IPv6 global unicast address is equivalent to an IPv4 public address, which is assigned to each Internet device to access other public IPv6 devices.

Question 2

An IPv6 ________ address is equivalent to an IPv4 private address.&#10;A) Global unicast&#10;B) Unique local&#10;C) Public unicast&#10;D) Private multicast

Accepted Answer

B) An IPv6 unique local unicast address is equivalent to an IPv4 private address, which is assigned to a device that is contained within a private network and cannot be used to communicate with other public devices without going through address translation.

Question 3

All addresses that begin (in hex) with the digits FF are ________ addresses.&#10;A) Global unicast&#10;B) Link local&#10;C) Multicast&#10;D) Broadcast

Accepted Answer

C) IPv6 multicast addresses all begin with the ff00::/8 prefix.

Question 4

All addresses that begin (in hex) with the digits FE80 are ________ addresses.&#10;A) Global unicast&#10;B) Broadcast&#10;C) Multicast&#10;D) Link local

Accepted Answer

D) IPv6 link local addresses all begin with the fe80::/10 prefix.

Question 5

When creating an IPv6 unique local unicast address range, what size is the unique global ID that must be specified?&#10;A) 40 bits&#10;B) 64 bits&#10;C) 32 bits&#10;D) 16 bits

Accepted Answer

A) The following structure is used when creating a unique local unicast address range:
The first 2 hex digits are FD.
The next 10 hex digits (40 bits) are used for a unique global ID.
The next 4 hex digits (16 bits) are used as a subnet field.
The last 16 hex digits (64 bits) are used as an interface ID field.

Question 6

When creating an IPv6 unique local unicast address range, what size is used for a subnet field?&#10;A) 20 bits&#10;B) 16 bits&#10;C) 10 bits&#10;D) 4 bits

Accepted Answer

B) The following structure is used when creating a unique local unicast address range:
The first 2 hex digits are FD.
The next 10 hex digits (40 bits) are used for a unique global ID.
The next 4 hex digits (16 bits) are used as a subnet field.
The last 16 hex digits (64 bits) are used as an interface ID field.

Question 7

Which of the following address category has no requirement for registering and has copies of the exact same addresses that are used by multiple organizations?&#10;A) Global unicast&#10;B) Public multicast&#10;C) Public unicast&#10;D) Unique local

Accepted Answer

D) Unique local addresses work like IPv4 private addresses. These do not need to be registered, and each organization can use the same exact address because the traffic is all local-only.

Question 8

All addresses that begin (in hex) with the digits FD are ________ addresses.&#10;A) Global unicast&#10;B) Link local&#10;C) Multicast&#10;D) Unique local

Accepted Answer

D) Only unique local addresses can begin with the FD prefix in IPv6.

Question 9

The ________ must be the same in all IPv6 addresses inside a small enterprise.&#10;A) Global routing prefix&#10;B) Subnet&#10;C) Interface ID&#10;D) Host field

Accepted Answer

A) The global routing prefix must be the same for all traffic within the small enterprise because these must be allocated to the organization by an issuing authority.

Question 10

The ________ is reserved and should not be used as an IPv6 address for any host.&#10;A) IPv6 subnet ID&#10;B) Subnet router anycast address&#10;C) Global prefix&#10;D) Interface ID

Accepted Answer

A) The IPv6 subnet ID (also called the subnet router anycast address) is reserved and should not be allocated to a host.
B) The IPv6 subnet ID (also called the subnet router anycast address) is reserved and should not be allocated to a host.

Question 11

For a company in North America to receive a global routing prefix, which organization must give ARIN the address to pass forward?&#10;A) IANA&#10;B) AfriNIC&#10;C) ISPs&#10;D) RIR

Accepted Answer

The answer of For a company in North America to...

Question 12

Which of the following organizations act as the RIR for North America in distributing IPv6 addresses?&#10;A) IANA&#10;B) ICANN&#10;C) ARIN&#10;D) ISPs

Accepted Answer

The answer of Which of the following organizations act as...

Question 13

Once ARIN receives a global routing prefix for distribution, it delivers it to ________.&#10;A) An ISP&#10;B) The requesting company directly&#10;C) IANA&#10;D) ICANN

Accepted Answer

The answer of Once ARIN receives a global routing prefix...

Question 14

When a company wishes to use IPv6 and needs a global routing prefix, to whom does the request go directly?&#10;A) The company's ISP&#10;B) IANA&#10;C) ICANN&#10;D) ARIN

Accepted Answer

The answer of When a company wishes to use IPv6...
