What is the difference between outbound and inbound replication?
Outbound replication is when a domain controller transmits replication information to other domain controllers on a network andInbound replication is when a domain controller receives updates to the Active Directory database from other domain controllers on the network.
To provide fault tolerance active directory utilizes what replication model?
RODC (Read-Only Domain Controller)
What is knowledge consistency check in Active Directory?
The Knowledge Consistency Checker (KCC) is a dynamic-link library (DLL) that runs as a distributed application on every domain controller. The KCC on each domain controller modifies data in its local instance of the directory in response to forest-wide changes, which are made known to the KCC by changes to data in the configuration directory partition. The KCC generates and maintains the replication topology for replication within sites and between sites by converting KCC-defined and administrator-defined (if any) connection objects into a configuration that is understood by the directory replication engine.
What is the process of copying directory data to multiple domain controllers known as?
Replication The data is available with all domain controller(DC) in case any DC fails other has same files with it.
What is the ISTG?
Windows 2000 Domain controllers each create Active Directory Replication connection objects representing inbound replication from intra-site replication partners. For inter-site replication, one domain controller per site has the responsibility of evaluating the inter-site replication topology and creating Active Directory Replication Connection objects for appropriate bridgehead servers within its site. The domain controller in each site that owns this role is referred to as the Inter-Site Topology Generator (ISTG). Krishna Pothula Answer: Intersite Topology Generator (ISTG), which is responsible for the connections among the sites. By default Windows 2003 Forest level functionality has this role.
What replication model provides fault tolerance in active directory?
outbond replication
What is the difference between authoritative and non-authoritative restore?
A nonauthoritative restore is the default method for restoring Active Directory. To perform a nonauthoritative restore, you must be able to start the domain controller in Directory Services Restore Mode. After you restore the domain controller from backup, replication partners use the standard replication protocols to update Active Directory and associated information on the restored domain controller. An authoritative restore brings a domain or a container back to the state it was in at the time of backup and overwrites all changes made since the backup. If you do not want to replicate the changes that have been made subsequent to the last backup operation, you must perform an authoritative restore. In this one needs to stop the inbound replication first before performing the An authoritative restore.
What component automatically creates replication links between domain controllers in the same site and schedules their replication activities?
Windows 2000 Domain controllers each create Active Directory Replication connection objects representing inbound replication from intra-site replication partners. For inter-site replication, one domain controller per site has the responsibility of evaluating the inter-site replication topology and creating Active Directory Replication Connection objects for appropriate bridgehead servers within its site. The domain controller in each site that owns this role is referred to as the Inter-Site Topology Generator (ISTG). Krishna Pothula Intersite Topology Generator (ISTG), which is responsible for the connections among the sites. By default Windows 2003 Forest level functionality has this role. ... Or the Distributed File System (DFS).
What is multiple-master replication?
Single-master replication can make it difficult for administrators to manage Active Directory objects, especially if they are located in remote offices and must work over a slow wide area network (WAN) link. To address this problem, Active Directory uses multiple-master replication, in which it is possible to make changes to domain objects on any domain controller, which replicates those changes to all of the other domain controllers.
What is a bridgehead server?
A Bridge head server is a domain controller that is used for intersite replication. This is the point of contact for a domain controller in another site. This passed replication traffic to a domain controller on another site. replication data is compressed and sent over IP or SMTP. To designate a preferred bridgehead server Open Active Directory Sites and Services -- In the console tree, right-click the domain controller that you want to make a preferred bridgehead server, and then click Properties -- On the General tab, click the intersite transport or transports for which this computer will be a preferred bridgehead server, and then click Add.
What is the full name of kcc?
KCC comes under Active Directory Section.KCC:Knowledge Consistency Checker.As soon as You install the second domain controller in a forest, a process called the knowledge consistency checker begins running on every domain controller. The KCC is responsible for generating the replication topology and dynamically handling the changes and failures within the replication topology.By default the KCC on every domain controller recalculates the replication topology for every 15mins.The more the replication topology, the more the processing power it takes to perform.Within a Site, a Windows server 2003 service known as the KCC automatically generates a topology for replication among the domain controllers in the domain using a ring structure.Th Kcc is a built in process that runs on all domain controllers.The KCC analyzes the replication topology within a site every 15 minute to ensure that it still works. If you add or remove a domain controller from the network or a site, the KCC reconfigures the topology to relect the change.AnswerKCC is Knowledge Consistency Checker, which creates the connection object that links the DCs into common replication topology and dictates the replication routes between one DC to another in Active Directory forest.
Which rodcs do not participate?
One of the new features receiving close attention in Windows 2008 is a new breed of domain controllers referred to as Read-Only Domain Controllers, also known as RODCs. The RODC hosts a copy of the Active Directory (AD) database like any other writable domain controller, but as its name implies, the contents replica of the domain database residing on the domain controller is read-only and write operations are not supported. It is equally important to mention that the RODCs do not participate in Active directory replication in the same fashion as writable domain controllers. The fundamental difference between RODC replication and the typical multimaster replication model between writable domain controllers is that RODCs replication is unidirectional. This means all changes from a writable domain controller are propagated to the RODCs. As a result, the RODC receives changes, but does not partake in or perform outbound replication with other domain controllers.
