1) Mention what is Active Directory?
An active directory is a directory structure used on Microsoft Windows based servers and computers to store data and information about networks and domains.
2) Mention what are the new features in Active Directory (AD) of Windows server 2012?
3) Mention which is the default protocol used in directory services?
The default protocol used in directory services is LDAP ( Lightweight Directory Access Protocol).
4) Explain the term FOREST in AD?
Forest is used to define an assembly of AD domains that share a single schema for the AD. All DC’s in the forest share this schema and is replicated in a hierarchical fashion among them.
5) Explain what is SYSVOL?
The SysVOL folder keeps the server’s copy of the domain’s public files. The contents such as users, group policy, etc. of the sysvol folders are replicated to all domain controllers in the domain.
6) Mention what is the difference between domain admin groups and enterprise admins group in AD?
|Enterprise Admin Group||Domain Admin Group|
7) Mention what system state data contains?
System state data contains
8) Mention what is Kerberos?
Kerberos is an authentication protocol for network. It is built to offer strong authentication for server/client applications by using secret-key cryptography.
9) Explain where does the AD database is held? What other folders are related to AD?
AD database is saved in %systemroot%/ntds. In the same folder, you can also see other files; these are the main files controlling the AD structures they are
10) Mention what is PDC emulator and how would one know whether PDC emulator is working or not?
PDC Emulators: There is one PDC emulator per domain, and when there is a failed authentication attempt, it is forwarded to PDC emulator. It acts as a “tie-breaker” and it controls the time sync across the domain.
These are the parameters through which we can know whether PDC emulator is working or not.
11) Mention what are lingering objects?
Lingering objects can exists if a domain controller does not replicate for an interval of time that is longer than the tombstone lifetime (TSL).
12) Mention what is TOMBSTONE lifetime?
Tombstone lifetime in an Active Directory determines how long a deleted object is retained in Active Directory. The deleted objects in Active Directory is stored in a special object referred as TOMBSTONE. Usually, windows will use a 60- day tombstone lifetime if time is not set in the forest configuration.
13) Explain what is Active Directory Schema?
Schema is an active directory component describes all the attributes and objects that the directory service uses to store data.
14) Explain what is a child DC?
CDC or child DC is a sub domain controller under root domain controller which share name space
15) Explain what is RID Master?
RID master stands for Relative Identifier for assigning unique IDs to the object created in AD.
16) Mention what are the components of AD?
Components of AD includes
17) Explain what is Infrastructure Master?
