federation servers.
You need to identify which technology or technologies must be deployed on the network before you
install the federation servers.
Which technology or technologies should you identify? (Each correct answer presents part of the
solution.
Choose all that apply.)
A. The Windows Internal Database feature
B. Microsoft SQL Server 2012
C. Network Load Balancing (NLB)
D. The Windows Identity Foundation 3.5 feature
E. Microsoft Forefront Identity Manager (FIM) 2010
Correct Answer: B,C
Explanation
Best practices for deploying a federation server farm. We recommend the following best practices for
deploying a federation server in a production environment:
* (A) Use NLB or some other form of clustering to allocate a single IP address for many federation
server computers.
* (D) If the AD FS configuration database will be stored in an SQL database, avoid editing the SQL
database from multiple federation servers at the same time.
* If you will be deploying multiple federation servers at the same time or you know that you will be
adding more servers to the farm over time, consider creating a server image of an existing federation
server in the farm and then installing from that image when you need to create additional federation
servers quickly.
* Reserve a static IP address for each federation server in the farm and, depending on your Domain
Name System (DNS) configuration, insert an exclusion for each IP address in Dynamic Host
Configuration Protocol (DHCP). Microsoft NLB technology requires that each server that participates
in the NLB cluster be assigned a static IP address.
