Explanation: Delegation is a process of assigning authority over a subdomain to another DNS server. It is often used to allow different teams or organizations to manage different parts of a DNS namespace. In this case, we need to delegate the subdomain "research.adatum.com" to a different DNS server in Azure.
To delegate a subdomain, we need to create an NS (Name Server) record in the parent domain (adatum.com) that points to the DNS server that will manage the subdomain (research.adatum.com). The NS record specifies the hostname of the DNS server responsible for the subdomain.
Here are the steps to delegate the subdomain "research.adatum.com" to a different DNS server in Azure:
Determine the hostname of the DNS server that will manage the subdomain. Let's assume it is "ns1.research.adatum.com".
In the Azure portal, navigate to the "adatum.com" DNS zone.
Click on the "Add record set" button.
In the "Name" field, enter "research".
In the "Type" field, select "NS".
In the "TTL" field, enter the desired Time-to-Live value (in seconds).
In the "Records" field, enter the hostname of the DNS server responsible for the subdomain ("ns1.research.adatum.com").
Click on the "Add" button to create the NS record.
After completing these steps, the subdomain "research.adatum.com" will be delegated to the DNS server "ns1.research.adatum.com", which can then be configured to manage the DNS records for that subdomain.
