The role that is considered a forest-level operations master is the Domain Naming Master. This role is vital in managing the names of domains within the forest and ensuring that every domain has a unique name. The Domain Naming Master is responsible for the addition and removal of domains in the forest and can prevent duplication of domain names, which is crucial for maintaining the integrity and structure of the Active Directory environment.

Other operations master roles function at the domain level, which means they are responsible for specific tasks within a single domain rather than across the entire forest. For instance, the Infrastructure Master deals with updates to objects that reside in other domains, the RID Master is responsible for managing the allocation of relative identifiers (RIDs) for security principals within a single domain, and the Schema Master controls changes to the Active Directory schema, which applies to the whole forest but does not manage domain names directly. This distinction highlights the specific responsibilities and scope of the Domain Naming Master compared to other operations master roles.
