Your network Directory domain. You have a single site.
You deploy a new Active Directory-integrated application on a server that runs Windows Server 2008. The application sends a large number of LDAP queries to the domain controllers.
You plan to install a new domain controller to respond to the LDAP queries.
You need to reduce the number of authentication requests client computers send to the new domain controller.
What should you do?
A. Create a new site and disable the Bridge all site links option.
B. Create a new site. Move the application server and the new domain controller to the new site.
C. Create a new organizational unit (OU). Move the application server and the new domain controller to the new OU.
D. Create two new sites. Move the application server to one site and the new domain controller to another site. Create a new site link that connects the two sites.
Correct Answer: B
Explanation/Reference:
Explanation:
When the client receives the SRV records, it performs a quick LDAP ping to all of them by sending out a bind query to UDP port 389. The first domain controller to respond is selected as the primary LDAP server by the client.
You cannot configure a preferred domain controller for a client. If you have a large LAN and you want to compartmentalize your clients based on their area of a campus LAN or MAN (metropolitan area network), you must structure your replication topology around multiple sites.
Therefore to reduce the number of authentication requests that the client computers would send to the new domain controller, you need to create a new site in the domain and then move the server on which application is installed and the new domain controller to the new site
