In a Windows Server lab environment, a server is promoted to a domain controller for the domain condorid.local, and an administrator subsequently creates a separate forward lookup zone named acme.local in DNS Manager. What is the primary difference in role between these two namespaces?

The lab uses two namespaces for different instructional purposes. `condorid.local` is the domain created during domain-controller promotion and is used when configuring and joining the client. `acme.local` is created later in DNS Manager as a separate forward lookup zone for practicing host and alias records. Treating them as interchangeable would confuse the AD domain setup with the sample zone used to test DNS record resolution. **Key takeaway:** The domain used for AD client membership and the sample DNS zone are distinct namespaces in this lab.\n\n**Glossary:** **Forest/domain**: The Active Directory structure created during promotion. **Forward lookup zone**: A DNS data collection used for name-based queries. **Zone apex**: The zone’s root name, here `acme.local`.
