Your network consists of an Active Directory domain named contoso.com. You have a computer named computer1.contoso.com. Your network is configured to use only IPv6. You need to request that a DNS record be created to enable users to connect to your computer by using the name dev.contoso.com. Which type of record should you request?
Correct Answer: B
Explanation/Reference: Explanation: The resolution of host names to IPv6 addresses is accomplished through DNS (apart from link-local addresses that are not stored by DNS and resolve automatically). The procedure is the same as for IPv4 address resolution with the computer name and IPv6 address pair being stored in a AAAA (quad-A) DNS resource record, which is equivalent to an A or host record for IPv4. Reverse DNS lookup that returns a computer name for an IPv6 address is implemented by a pointer (PTR) DNS resource record that is referred to the IPv6 reverse lookup zone (or tree) ipv6.arpa, which is the equivalent of the in-addr.arpa reverse lookup zone in Ipv4. AAAA An AAAA (quad-A) resource record resolves a host name to anIPv6 address.
