What naming contexts are replicated across an entire active directory forest?
Active Directory NC (Naming Context's)Active Directory consists of three partitions or naming contexts (NC) Domain, Configuration and Schema Naming ContextsEach are replicated independentlyAn Active Directory forest has single schema and configuration Every domain controller (DC) holds a copy of each (schema, configuration NC's)Forest can have multiple domains Every domain controller in a domain holds a copy of the domain NC
What naming context is replicated across the domain?
Schema naming context and configuration naming context is replicated across domain in the forest
Which naming context is replicated across the domain?
Schema naming context and configuration naming context is replicated across domain in the forest
What is active directory services?
Active Directory service is used to store information about the network resources across a domain and also centralize the network.
What is Active Directory Recycle Bin?
Active Directory Recycle Bin is a feature that helps minimize directory service downtime by enhancing your ability to preserve and restore accidentally deleted Active Directory objects without restoring Active Directory data from backups, restarting Active Directory Domain Services (AD DS), or rebooting domain controllers. When you enable Active Directory Recycle Bin feature, all link-valued and non-link-valued attributes of the deleted Active Directory objects are preserved and the objects are restored in their entirety to the same consistent logical state that they were in immediately before deletion. For example, restored user accounts automatically regain all group memberships and corresponding access rights that they had immediately before deletion, within and across domains. Active Directory Recycle Bin is functional for both AD DS and Active Directory Lightweight Directory Services (AD LDS) environments. Mohannad Hamid
Why are bridgehead servers used ad replication?
Bridgehead servers are used in Active Directory replication to reduce network traffic by serving as intermediaries between sites, thus minimizing the number of replication connections needed. They also help control the flow of replication data by efficiently routing updates between domain controllers in different sites. This ensures that changes to the directory are replicated efficiently across the network.
What is active deractory service?
Active Directory Service refers to a directory service developed by Microsoft for Windows domain networks. It provides a centralized location for network management, allowing administrators to manage users, computers, and resources within a domain. Active Directory facilitates authentication, authorization, and policy enforcement, ensuring secure access to network resources. Additionally, it supports various services like Group Policy, which helps in deploying and managing settings across multiple computers and users.
What master database contains definitions of all objects in the Active Directory?
The NTDS.DIT This is the main AD database. NTDS stands for NT Directory Services. The DIT stands for Directory Information Tree. The Ntds.dit file on a particular domain controller contains all naming contexts hosted by that domain controller, including the Configuration and Schema naming contexts. A Global Catalog server stores the partial naming context replicas in the Ntds.dit right along with the full Domain naming context for its domain. Windows 2000 Active Directory data store, the actual database file, is %SystemRoot%\ntds\NTDS.DIT. The ntds.dit file is the heart of Active Directory including user accounts. Active Directory's database engine is the Extensible Storage Engine ( ESE ) which is based on the Jet database used by Exchange 5.5 and WINS. The ESE has the capability to grow to 16 terabytes which would be large enough for 10 million objects. Back to the real world. Only the Jet database can maniuplate information within the AD datastore. For information on domain controller configuration to optimize Active Directory, see Optimize Active Directory Disk Performance The Active Directory ESE database, NTDS.DIT, consists of the following tables: * Schema table the types of objects that can be created in the Active Directory, relationships between them, and the optional and mandatory attributes on each type of object. This table is fairly static and much smaller than the data table. * Link table contains linked attributes, which contain values referring to other objects in the Active Directory. Take the MemberOf 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. * Data table users, groups, application-specific data, and any other data stored in the Active Directory. The data table can be thought of as having rows where each row represents an instance of an object such as a user, and columns where each column represents an attribute in the schema such as GivenName. From a different perspective, Active Directory has three types of data * Schema information definitional details about objects and attributes that one CAN store in the AD. Replicates to all domain controllers. Static in nature. * Configuration information configuration data about forest and trees. Replicates to all domain controllers. Static as your forest is. * Domain information object information for a domain. Replicates to all domain controllers within a domain. The object portion becomes part of Global Catalog. The attribute values (the actual bulk of data) only replicates within the domain. Although GUIDs are unique, they are large. AD uses distinguished name tag ( DNT ). DNT is a 4-byte DWORD value which is incremented when a new object is created in the store. The DNT represents the object's database row number. It is an example of a fixed column. Each object's parent relationship is stored as a parent distinguished name tag ( PDNT ). Resolution of parent-child relationships is optimized because the DNT and PDNT are indexed fields in the database. For more technical info on the AD datastore and its organization, a good starting point is the Active Directory Database Sizing document. The size of ntds.dit will often be different sizes across the domain controllers in a domain. Remember that Active Directory is a multi-master independent model where updates are occuring in each of the ADs with the changes being replicated over time to the other domain controllers. The changed data is replicated between domain controllers, not the database, so there is no guarantee that the files are going to be the same size across all domain controllers.

What are the AD related roles in Windows Server 2008 R2?
Windows Server 2008 has five Active directory related roles. below are the list 1. Active Directory Domain Services (Identity): AD DS it provides the functionality of an identity and access (IDA) solution for enterprise networks. It also provides the mechanisms to support, manage, and configure resources in distribution network environments. 2. Active Directory Lightweight Directory Services (Applications): AD LDS formerly known as Active directory application mode (ADAM), provides support for directory-enabled applications. 3. Active Directory Certificate Services (Trust): AD CS to set up a certificate authority for issuing digital certificates as a part of a public key infrastructure (PKI) that binds the identity of a person, device or service to corresponding private key. Certificates can be used to authenticate users and computers, provide web-based authentication, support smart card authentication, and support application, including secure wireless n/w, vpn, Ipsec, EFS, and more. 4. Active Directory Rights management Services (Integrity): AD RMS is an information-protection technology that enables you to implement persistent usage policy templates (for documents) that define allowed and unauthorized use whether online, offline, inside, or outside the firewall. 5. Active Directory Federation Services (Partnership): AD FS enable an organization to extend IDA across multiple platforms, including both window and non-windows environments, and to project identity and access rights across security boundaries to trusted partners.

What is an example of active insufficiency in the context of muscle function?
Active insufficiency in muscle function occurs when a muscle is unable to generate enough force due to being stretched across two joints simultaneously. An example of this is the hamstrings being stretched across both the hip and knee joints, limiting their ability to generate force effectively.
