- C.Windows Internet Name Service
- D.Domain Name System
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
| The Knowledge Consistency Checker (KCC) is responsible for establishing the replication topology and ensuring that all domain controllers are kept up-to-date. |

A system administrator for an Active Directory environment that consists of three sites
wants to configure site links to be transitive. Which of the following Active Directory
objects are responsible for representing a transitive relationship between sites?
- A.Additional sites
- B.Additional site links
- C.Bridgehead servers
- D.Site link bridges
- Answer & Explanation
- Report
Answer : [D]
Explanation :
Explanation :
| Site link bridges are designed to allow site links to be transitive. That is, they allow site links to use other site links to transfer replication information between sites. By default, all site links are bridged. However, you can turn off transitivity if you want to override this behavior. |
28.
You have configured your Active Directory environment with multiple sites and have placed
the appropriate resources in each of the sites. You are now trying to choose a protocol for
the transfer of replication information between two sites. The connection between the two
sites has the following characteristics:
--> The link is generally unavailable during certain parts of the day because of an unreliable network provider.
--> The replication transmission must be attempted whether the link is available or not. If the link was unavailable during a scheduled replication, the information should automatically be received after the link becomes available again.
--> Replication traffic must be able to travel over a standard Internet connection.
Which of the following protocols meets these requirements?
--> The link is generally unavailable during certain parts of the day because of an unreliable network provider.
--> The replication transmission must be attempted whether the link is available or not. If the link was unavailable during a scheduled replication, the information should automatically be received after the link becomes available again.
--> Replication traffic must be able to travel over a standard Internet connection.
Which of the following protocols meets these requirements?
- A.DHCP Policy
- B.DNS server options
- C.DNS server zone scope settings
- D.DNS server zone scope settings
- E.DNS server client subnet settings
- F.DNS server recursion policy settings
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
| Simple Mail Transfer Protocol was designed for environments in which persistent connections may not always be available. SMTP uses the store-and-forward method to ensure that information is not lost if a connection cannot be made. |

A system administrator suspects that there is an error in the replication configuration. How
can the system administrator look for specific error messages related to replication?
- A.By using the Active Directory Sites and Services administrative tool
- B.By using the Computer Management tool
- C.By going to Event Viewer -> System Log
- D.By going to Event Viewer ➢ Directory Service Log
- Answer & Explanation
- Report
Answer : [D]
Explanation :
Explanation :
| The Directory Service event log contains error messages and information related to replication. These details can be useful when you are troubleshooting replication problems. |

Christina is responsible for managing Active Directory replication traffic for a mediumsized
organization. Currently, the environment is configured with a single site and the
default settings for replication. The site contains more than 50 domain controllers, and the
system administrators are often making changes to the Active Directory database. Recently,
network administrators have complained that Active Directory traffic is consuming a large
amount of network bandwidth between portions of the network that are connected by slow
links. Ordinarily, the amount of replication traffic is reasonable, but recently users have
complained about slow network performance during certain hours of the day.
Christina has been asked to alleviate the problem while meeting the following requirements:
--> Be able to control exactly when replication occurs.
--> Be able to base Active Directory replication on the physical network infrastructure.
--> Perform the changes without creating or removing any domain controllers.
Which two of the following steps can Christina take to meet these requirements? (Choose two.)
Christina has been asked to alleviate the problem while meeting the following requirements:

--> Be able to base Active Directory replication on the physical network infrastructure.
--> Perform the changes without creating or removing any domain controllers.
Which two of the following steps can Christina take to meet these requirements? (Choose two.)
- A.Create and define connection objects that specify the hours during which replication will occur.
- B.Create multiple site links.
- C.Create a site link bridge.
- D.Create new Active Directory sites that reflect the physical network topology
- E.Configure one server at each of the new sites to act as a bridgehead server.
- Answer & Explanation
- Report
Answer : [A, D]
Explanation :
Explanation :
| By creating new sites, Christina can help define settings for Active Directory replication based on the environment’s network connections. She can use connection objects to define further the details of how and when replication traffic will be transmitted between the domain controllers. |
