ITPEC FE Morning October 2020 Question 61

Enterprise Architecture — Application Architecture — identifies the layer that describes system functions supporting business processes.

Enterprise Architecture (EA) has four layers:

• •Business Architecture — business processes and information flows for strategy
• •Data Architecture — data contents, relationships, and structures for operations
• •Application Architecture — functions or system configurations that support business processes
• •Technology Architecture — technical components for development and operations

The question asks specifically about the application architecture layer, which sits between the data layer and the technology layer, describing what systems and functions are needed to support the business.

Why not others:
- (a) Describes business processes and information flows — this is the Business Architecture layer
- (b) Describes data contents, relations, and structures — this is the Data Architecture layer
- (d) Describes technical components for development and operations — this is the Technology Architecture layer

Key rule: Application architecture = system functions that support business processes; remember the EA stack: Business → Data → Application → Technology.
