146 Active Directory Questions And Answers
42⟩ What is the the Directory Partitions?
Schema Partition:
Only one schema partition exists per forest. The schema partition is stored on all domain controllers in a forest. It contains definitions of all objects and attributes that can be created in the directory.
Configuration Partition:
There is only one configuration partition per forest. the configuration partition contains information about the forest-wide active directory structure.
Domain Partition:
Many domain partitions can exist per forest. Domain partitions are stored on each domain controller in a given domain. A domain partition contains information about users, groups, computers, and organizational units.
Application Partition:
It stores information about applications in Active Directory. It is replicated only to specific domain controllers.
43⟩ How to Seize FSMO Roles?
ntdsutil - type roles - connections - connect servername - q - type seize role - at the fsmo maintenance prompt - type seize rid master
44⟩ How to transfer FSMO Roles?
ntdsutil - type roles - connections - connect servername - q - type transfer role - at the fsmo maintenance prompt - type trasfer rid master
45⟩ What is a Flexible Single Master Operation?
It is a role that only one DC can (or should) hold at any given time within its boundary.
Schema Master - Use MMC "Active Directory Schema Snap-in". The schema master domain controller controls all updates and modifications to the schema. Once the Schema update is complete, it is replicated from the schema master to all other DCs in the directory.
Domain Naming Master - Use "Active Directory Domains and Trusts". It controls the addition or removal of domains in the forest.
Primary Domain Controller (PDC) Emulator - Use the "ADUC" . The PDC emulator is necessary to synchronize time in an enterprise.
Relative ID Master (RID Master) - Use "ADUC". All objects have a SID and a domain SID. The RID assigns relative IDs to each domain controller.
Infrastructure Master - Use the "ADUC". Updates group membership information when users from other domains are moved or renamed.
The Infrastructure Master (IM) role should be held by a domain controller that is not a Global Catalog server (GC). If the Infrastructure Master runs on a Global Catalog server it will stop updating object information because it does not contain any references to objects that it does not hold.
46⟩ What is the ISTG - Intersite topology generator?
ISTG is responsible for creating Active Directory Replication Connection objects for appropriate bridgehead servers within its site. Intersite replication can utilize either RPC over IP or SMTP to convey replication data.
Bridgehead server - A domain controller that is used to send replication information to one or more other sites
DHCP Superscope:
A rage of IP address that span several subnets. The DHCP server can assign these address to clients that are on several subnets.
DHCP Scope:
A range of IP address that the DHCP server can assign to clients that are on one subnet
A stub zone
It is a copy of a zone that contains only those resource records necessary to identify the authoritative Domain Name System (DNS) servers for that zone. A stub zone is used to resolve names between separate DNS namespaces. This type of resolution may be necessary when a corporate merger requires that the DNS servers for two separate DNS namespaces resolve names for clients in both namespaces.
A stub zone consists of: SOA, NS, A Records
47⟩ What is the KCC (Knowledge consistency checker)?
The KCC generates and maintains the replication topology for replication within sites and between sites. KCC runs every 15 minutes.
48⟩ How you add a user in ad by commandline?

49⟩ How to do the work with human?

50⟩ What is Lightweight Directory Access Protocol?
LDAP is the directory service protocol that is used to query and update AD. LDAP naming paths are used to access AD objects and include the following:
★ Distinguished names
★ Relative Distinguished names
51⟩ What is the minimum requirement for installing AD?
★ Windows Server, Advanced Server, Data center Server
★ Minimum Disk space of 200 MB for AD and 50 MB for log files
★ NTFS partition
★ TCP/IP Installed and Configured to use DNS
★ Administrative privilege for creating a domain in existing network
52⟩ How will you verify whether the AD installation is proper with SRV resource records?
Verify SRV Resource Records:
After AD is installed, the DC will register SRV records in DNS when it restarts. We can check this using DNS MMC or nslookup command.
53⟩ How to Verifying SYSVOL?
If SYSVOL folder is not properly created data stores in SYSVOL such are scripts, GPO, etc will not be replicated between DCs.
First verify the following folder structure is created in SYSVOL.
★ Domain
★ Staging
★ Staging areas
★ Sysvol
Then verify necessary shares are created.
54⟩ How to verifying database and Log files?
Make sure that the following files are there at %systemroot%ntds
Ntds.dit, Edb.*, Res*.log
55⟩ What is NTDS.DIT?
This is the AD database and stores all AD objects. Default location is SystemRoot%ntdsNTDS.DIT.
Active Directory's database engine is the Extensible Storage Engine which is based on the Jet database and can grow up to 16 TB.
56⟩ What is NTDS.DIT schema table?
The types of objects that can be created in the Active Directory, relationships between them, and the attributes on each type of object. This table is fairly static and much smaller than the data table.
57⟩ What is NTDS.DIT Link table?
Link Table contains linked attributes, which contain values referring to other objects in the Active Directory. Take the Member Of attribute on a user object. That attribute contains values that reference groups to which the user belongs. This is also far smaller than the data table.
58⟩ What is NTDS.DIT Data table?
Data Table users, groups, application-specific data, and any other data stored in the Active Directory.
59⟩ How many types of Active Directory data?
★ Active Directory has three types of data:
★ Schema information
★ Configuration information
★ Domain information
60⟩ What is Domain information in Active Directory?
Object information for a domain. Replicates to all DCs within a domain. The object portion becomes part of GC. The attribute values only replicates within the domain.
