You are designing an enterprise‐level Windows Communication Foundation (WCF) application. User
accounts will migrate from the existing system. The new system must be able to scale to
accommodate the increasing load.
The new servers are experiencing significant stress under load of large‐scale role changes.
You need to ensure that the application can handle the stress.
Which authorizations should you redesign? (Each correct answer presents a complete solution.
Choose all that apply.)
A.
Role‐based approach
B.
Identity‐based approach
C.
Resource‐based trusted subsystem model
D.
Resource‐based impersonation/delegation model
The answer should be
A. Role-based approach
B. Identity-based approach

93 is not the same.
I think that when “new servers experience significant stress under the load of large-scale role changes”, we should try to minimize the impact of migration on the server. Thus, we partially simplify authorization using the trusted subsystem model for downstream services.
So, A & C may be correct in some cases.
