Active Directory 面试题与答案
问题 16. What is the PDC Emulator role in Active Directory?
The Primary Domain Controller (PDC) Emulator is a role in Active Directory that plays a crucial role in backward compatibility with older Windows NT systems. It acts as the primary time source for the domain and handles certain authentication requests.
Example:
If a user's password is changed, the PDC Emulator ensures that the change is replicated to all other domain controllers.
问题 17. How does Active Directory support multi-master replication?
Active Directory uses multi-master replication, meaning that changes can be made on any domain controller, and those changes are then replicated to all other domain controllers. This ensures that no single domain controller becomes a bottleneck for changes.
Example:
If a user is added to a group on one domain controller, the change is replicated to all other domain controllers in the domain.
问题 18. What is the Schema Master role in Active Directory?
The Schema Master is a role in Active Directory responsible for managing changes to the schema. It controls updates and modifications to the schema, which defines the structure and attributes of objects in the directory.
Example:
When a new attribute or object class is added, the Schema Master ensures that the change is replicated to all other domain controllers.
问题 19. Explain the purpose of the Infrastructure Master role.
The Infrastructure Master is responsible for updating references from objects in its domain to objects in other domains. It ensures that cross-domain object references are kept up to date.
Example:
If a user in one domain is a member of a group in another domain, the Infrastructure Master updates the reference to the user's security identifier (SID).
问题 20. What is the purpose of the Domain Naming Master role?
The Domain Naming Master is a role in Active Directory responsible for managing the addition and removal of domains in the forest. It ensures that domain names are unique within the forest.
Example:
When a new domain is added to the forest, the Domain Naming Master verifies that the domain name is unique across all domains in the forest.
