A Samba 4 server provides DNS information regarding an Active Directory Domain. All other DNS information is provided by an additional DNS server. Which of the following solutions ensures that the clients of the Samba server can look up all DNS records including those from the domain?

1. A. The additional DNS server is configured in the file /etc/resolv.conf on the Samba server and the option dns forwarder = yes is set in smb.conf.
2. B. The search domain of all clients is set to the Active Directory domain name. All clients query only the additional DNS server and not a domain controller.
3. C. Both the Samba server and the additional DNS server are configured on the clients. This ensures that the Samba server is listed first in each client's resolv.conf.
4. D. All clients are configured to send DNS queries to the additional DNS server only. The Samba server's smb.conf contains the option wins dns proxy = yes to provide all domain-related naming information via the NetBIOS name service independently from DNS.
5. E. The additional DNS server is configured in the option dns forwarder in smb.conf. All clients query the Samba server for any DNS information. — đáp án hiện tại
