Which statement(s) about IPv6 addresses are true?
1. Leading zeros are required.
2. Two colons (::) are used to represent successive hexadecimal fields of zeros.
3. Two colons (::) are used to separate fields.
4. A single interface will have multiple IPv6 addresses of different types.

A. 1 and 3

B. 2 and 4

C. 1, 3 and 4

D. All of the above

Answer: Option B

Solution(By Examveda Team)

In order to shorten the written length of an IPv6 address, successive fields of zeros may be replaced by double colons. In trying to shorten the address further, leading zeros may also be removed. Just as with IPv4, a single device's interface can have more than one address; with IPv6 there are more types of addresses and the same rule applies. There can be link-local, global unicast, and multicast addresses all assigned to the same interface.

Which of the following is true when describing a global unicast address?

A. Packets addressed to a unicast address are delivered to a single interface.

B. These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.

C. These are like private addresses in IPv4 in that they are not meant to be routed.

D. These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.

Which of the following is true when describing an anycast address?

A. Packets addressed to a unicast address are delivered to a single interface.

B. Packets are delivered to all interfaces identified by the address. This is also called one-to-many addresses.

C. This address identifies multiple interfaces and the anycast packet is only delivered to one address. This address can also be called one-to-one-of-many.

D. These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.

Which of the following is true when describing a multicast address?

A. Packets addressed to a unicast address are delivered to a single interface.

B. Packets are delivered to all interfaces identified by the address. This is also called a one-to-many address.

C. Identifies multiple interfaces and is only delivered to one address. This address can also be called one-to-one-of-many.

D. These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
