You are a Solution Architect and design the solution topology. 
Please select four principles that you would follow to create a well-architected solution.

Answer options:

A.Accountability
B.Trust and privacy
C.Fairness
D.Availability and recoverability
E.Security
F.Transparency
G.Performance and scalability

Correct Answers: B, D, E and G 
When a Solution Architect designs the solution, he or she must follow the pillars of great system architecture. The pillars include: Security — includes perimeter control and data security. You need to use the Dynamics 365 security model, Azure AD, Azure Conditional Access, Data Loss Prevention policies in your architecture.
Empowering end users — the architecture should be open for the users to extend or re-use apps, solutions, or components.
Trust and Privacy — the solution should comply with rules, laws, and privacy regulations.
Maintainability — the solution must be well documented, which helps with its maintenance. Also, the solution should not break from the frequent Power Platform updates.
Availability and recoverability — you need to know the recovery capabilities of the solution and all components. The system must be designed for recovery within the required time.
Performance and scalability — the solution must be scalable and use optimal resources for high performance.
Efficiency and operations — the solution must use resources efficiently to minimize the costs and drive up quality and speed.
Shared responsibility — the users are responsible for application security and operations. At the same time, Azure is responsible for providing infrastructure and security of the cloud services.
Design choices — the system architecture must balance security, availability, efficiency, and performance from one side and the operational costs, delivery time, and agility from another.
All other options are incorrect because Accountability, Fairness, and Transparency are parts of the six principles of Responsible AI.
