Q
Which statement(s) about IPv6 addresses are true?
AA. Leading zeros are required
BB. Two colons (::) are used to represent successive hexadecimal fields of zeros
CC. Two colons (::) are used to separate fields
DD. A single interface cannot have multiple ipv6 addresses of different types
Correct Answer:
B. B. Two colons (::) are used to represent successive hexadecimal fields of zeros
Explanation:
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.
