Which of the following option must be selected to create an additional domain controller in an existing domain environment?

Extra AD domain controllers are not recommended because they are hard to administer. However, you may need an extra domain (Child domain controller) in the following scenarios. In this blog, we will explore adding a child domain to an existing forest. The Active Directory Domain Services (AD DS) design teams have finished the design phase for the new AD DS environment and now it is time to add a new child domain to the environment. The domain name system must have been configured to support the new child domain.

Let’s understand in a simple way –

  1. Assume the two different companies have different hardware resources. Some prefer high-quality and reliable hardware, and some prefer to save money. It is preferable to have two separate domains on different hardware in this situation.
  2. The two companies have different IT support staff. Imagine a single domain and suppose if a technician set wrong permission unintentionally, it can cause e the whole AD date to be compromised.

In this blog, we will see how to deploy and configure a Child Domain controller on Windows server 2019 in a lab environment. The following steps are helpful to you.

Lab Scenario

  • Deploy once PDC (Primary Domain Controller). In our case, we have a PDC.
  • A static IP address was configured with the DNS entry pointing to the corporate DNS server.
  • The Server DNS suffix has been updated on the new DC computer name.
  • DNS has been configured with the child domain.

Now we add a Child domain on PDC.
