IS A
Active Directory supports dynamic registration of domain controller addresses in DNS. After Active Directory has been installed during domain controller creation, the Net Logon service dynamically creates records in the DNS database that are used to locate the server.

While restarting the Netlogon service could well do this… It would also interfere with many other operations that the domain looks after.
Therefore the “Microsoft” answer is most likely going to be:
“D” – ipconfig / registerdns

“The ipconfig /registerdns command provides you with a means to manually initiate dynamic registration for the DNS names and IP addresses configured at a computer. This option can assist in troubleshooting a failed DNS name registration or in resolving a dynamic update problem between a client and the DNS server without restarting the client.”
