    If a DNS server suffers a catastrophic failure, what happens tothe clients being served by it?

    • They will be unable to automatically renew their IP address.

    • They will be unable to connect to a server using a Host name.

    • They will be unable to connect to the server using a NetBIOS name.

    • They will be unable to connect to a server using its IP address

    Correct Answer
    A. They will be unable to connect to a server using a Host name.
    Explanation
    If a DNS server suffers a catastrophic failure, the clients being served by it will be unable to connect to a server using a Host name. This is because the DNS server is responsible for translating domain names (Host names) into IP addresses. Without a functioning DNS server, the clients will not be able to resolve the Host name to its corresponding IP address, making it impossible for them to establish a connection to the server.
