What does Ksenia create on her Windows 2019 server after setting up the DNS Server role?

The correct choice highlights that the stub zone will contain NS records. A stub zone is a partial replica of a primary zone that includes only the necessary resource records, such as Name Server (NS) records, that help the DNS server locate the authoritative DNS servers for the zone. Essentially, it serves as a directory pointer that assists in the resolution of names from the primary zone without transferring all the data that a full zone would entail.

The function of a stub zone is to simplify name resolution across different DNS zones by ensuring that DNS servers can efficiently direct queries to the authoritative servers, which improves the response time and management of DNS traffic. This characteristic is fundamental to the role of stub zones in a DNS architecture, making NS records a crucial component.

In contrast, while the stub zone does interact with other types of DNS configurations, details like its relationship or inability to access a primary zone or contain host records pertain to different DNS concepts that do not clarify its function as a repository of NS records. Recognizing these distinctions helps in understanding how stub zones fit into broader DNS strategies.
