  5. Active Directory creates a __________ with the idea that all writeable domain controllers in a domain should communicate Active Directory information to each other, in addition to communicating forest-wide information with other domains.
    a) replication topology
    b) domain topology
    c) replication strategy
    d) domain strategy
    • Ans: a
    • Difficulty: Hard
    • Section Ref: Introducing Active Directory Sites
    • Feedback: Active Directory creates a replication topology with the idea that all writeable domain controllers in a domain should communicate Active Directory information to each other, in addition to communicating forest-wide information with other domains. Sites and subnets defined within Active Directory will dictate the path used by replication traffic on the network, as well as form the basis for how Active Directory information is distributed.

    a) Active Directory
    b) administrative labor
    c) bandwidth
    d) financial support
    • Ans: c
    • Difficulty: Easy
    • Section Ref: Introducing Active Directory Sites
    • Feedback: The primary goal of intersite replication is to minimize bandwidth usage. Unlike intrasite replication, intersite replication will compress data that is replicated between sites, thus reducing the amount of network traffic used by Active Directory replication.
  12. When configuring a site link object, which attribute allows the administrator to define the path that replication will take?
    a) cost
    b) schedule
    c) frequency
    d) none of the above
    • Ans: a
    • Difficulty: Easy
    • Section Ref: Introducing Active Directory Sites
    • Feedback: Assigning a cost to a site link object allows the administrator to define the path that replication will take. If more than one path can be used to replicate information, cost assignments will determine which path is chosen first.
  13. For both intrasite and intersite replication, what protocol does Active Directory use for all replication traffic?
    a) RPC over SMTP
    b) RPC over TCP
    c) RPC over IP
    d) RPC over ARP
    • Ans: c
    • Difficulty: Medium
    • Section Ref: Introducing Active Directory Sites
    • Feedback: For both intrasite and intersite replication, Active Directory uses Remote Procedure Calls over Internet Protocol (RPC over IP) by default for all replication traffic. RPC is commonly used to communicate with network services on various computers, whereas IP is responsible for the addressing and routing of the data. RPC over IP replication keeps data secure while in transit by using both authentication and encryption.
  14. What is an alternative solution for intersite replication when a direct or reliable IP connection is not available?
    a) IRC
    b) SMTP
    c) TCP/IP
    d) ICMP

  15. How often does replication occur in intersite replication?
    a) 15 minutes
    b) 30 minutes
    c) 90 minutes
    d) 180 minutes
    • Ans: d
    • Difficulty: Medium
    • Section Ref: Introducing Active Directory Sites
    • Feedback: The default replication frequency for a new site link is 180 minutes, but it can be configured to take place as frequently as every 15 minutes and as infrequently as once per week.
  16. The ISTG automatically assigns one server in each site as the bridgehead server unless you override this by establishing a list of __________ bridgehead servers.
    a) manual
    b) preferred
    c) static
    d) designated
    • Ans: b
    • Difficulty: Easy
    • Section Ref: Introducing Active Directory Sites
    • Feedback: The ISTG automatically assigns one server in each site as the bridgehead server unless you override this by establishing a list of preferred bridgehead servers. The advantage of administratively assigning a preferred bridgehead server list is that you can determine which servers have the best processing power for handling replication traffic.
  17. What defines a chain of site links by which domain controllers from different sites can communicate?
    a) site link bridgeb) site chainc) site chain bridged) site link chain
    • Ans: a
    • Difficulty: Medium
    • Section Ref: Introducing Active Directory Sites
    • Feedback: A site link bridge defines a chain of site links by which domain controllers from different sites can communicate. In cases in which there is a centralized site that connects two branch sites via site links, the site link bridge creates a direct link between the branch sites using the total cost of both site links to the central site.
  18. What command-line tool used for monitoring Active Directory provides functionality that includes performing connectivty and replication tests?
    a) dcdiag
    b) netdiag
    c) dcpromo

    a) Dcdiag
    b) Repdiag
    c) Repadmin
    d) Netstat
    • Ans: c
    • Difficulty: Easy
    • Section Ref: Introducing Active Directory Sites
