You are the Office 365 administrator for your company. The company has a single office.
You have the following requirements:
• You must configure a redundant Active Directory Federation Services (AD FS)
implementation.
• You must use a Windows Internal Database to store AD FS configuration data.
• The solution must use a custom login page for external users.
• The solution must use single sign-on for internal users.
You need to deploy the minimum number of servers.
How many servers should you deploy?
A.
2
B.
4
C.
6
D.
16
B 4
B – 4
2 Proxies
2 Fed Servers with windows internal db installed on one
B 4 is correct. I thought about 2 additional servers for the NLB but I read that those can also be installed on the ADFS servers.
is there a reason it is 4? Why do we need 2 proxies? I am just trying to understand why we need 2 proxies.
Says in the question you need a redundant ADFS implementation so you need 2 fed servers and then 1 proxy for each fed server.
Nop,
the answer why you need “4” … it’s beacause “The solution must use a custom login page for external users…” … external users pass via ADFS Proxy (2 server in HA&BC + 2 Internal Server for ADFS in HA&BC)
agree with Michael.
It is recommended practice to deploy AD FS with redundancy/high-availability, as well as a secondary Disaster Recovery site, if possible. Standard AD FS configurations opt for a 1:1 ratio of federation servers to proxy servers. For these reasons, the minimum recommended configuration of servers would be two federation servers and two proxy servers, with each fed/proxy pair hosted on separate physical servers.
