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.

Read-only domain controllers (RODCs) in Active Directory, intended for use in branch office or other scenarios where a domain controller may reside in a low physical security environment. The RODC holds a non-writeable copy of Active Directory, and redirects all write attempts to a Full Domain Controller. It replicates all accounts except sensitive ones.In RODC mode, credentials are not cached by default. Moreover, only the replication partner of the RODC needs to run Windows Server 2008. Also, local administrators can log on to the machine to perform maintenance tasks without requiring administrative rights on the domain.
What are the advantages of Read Only Domain Controller?
Read-Only Domain Controllers (RODCs) offer enhanced security and reduced risk by storing only a read-only copy of the Active Directory database, making them less vulnerable to unauthorized changes. They are ideal for remote or branch office locations where physical security may be a concern, as they can authenticate users and cache credentials without exposing sensitive data. Additionally, RODCs can improve performance for local users by providing faster access to directory services while minimizing replication traffic to the main domain controllers.
Domain controllers located in different sites will participate in intrasite replication?
Only one domain controller will be used per site to replicate to another site(process called as intersite replication) it could be a bridge head server(selected DC to do replication from the site)or DC selected by ISTG protocol if enabled. there would be lot of DCs in intrasite replication within a site.
True or false Domain controllers located in different sites will participate in intrasite replication?
False Only one domain controller will be used per site to replicate to another site(process called as intersite replication) it could be a bridge head server(selected DC to do replication from the site)or DC selected by ISTG protocol if enabled. there would be lot of DCs in intrasite replication within a site.
What are the major benefits of using RODCs?
the following benefits: * Improved security * Faster logon times * More efficient access to resources
What are the areas on DNA where replication occurs called?
DNA replication begins in areas of DNA molecules are called origins of replication.
Replication that occurs between sites is called?
intersite replication
Is origin of replication or replication fork same?
No, the origin of replication is a specific sequence of DNA where the replication process starts, while the replication fork is the Y-shaped structure formed during DNA replication where the DNA strands are unwound and replicated. The origin of replication initiates the formation of the replication fork.
Compare the number of replication forks in prokaryotic and eukaryotic DNA during replication?
Prokaryotic DNA replication has a single origin of replication, leading to two replication forks. In contrast, eukaryotic DNA replication has multiple origins of replication, resulting in multiple replication forks forming along the DNA molecule.
Difference between eukaryotic DNA replication and bacterial replication?
Eukaryotic DNA replication is more complex and occurs in the nucleus of the cell, involving multiple origins of replication and coordination with the cell cycle. Bacterial replication is simpler and occurs in the cytoplasm, often with a single origin of replication and a faster rate of replication. Eukaryotic replication also involves telomeres and histones, which are not present in bacterial replication.
In prokaryotes where does DNA replication occur in the cell?
In prokaryotes, DNA replication occurs in the cytoplasm. The replication process begins at the origin of replication on the DNA molecule and proceeds bidirectionally. Multiple replication fork structures are formed to speed up the replication process.
