Which technology or technologies should you identify?

Your network contains an Active Directory domain named contoso.com.
You plan to deploy an Active Directory Federation Services (AD FS) farm that will contain eight 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.
Network Load Balancing (NLB)

B.
Microsoft Forefront Identity Manager (FIM) 2010

C.
The Windows Internal Database feature

D.
Microsoft SQL Server 2012

E.
The Windows Identity Foundation 3.5 feature

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 a 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.
