Question

Options

• Atechnology, information, applications, business strategy
• Barchitecture, applications, technology, compliance
• Csecurity, technology, business, strategy
• Drisk, technology, business strategy, information

• A
  91% (41)
• B
  2% (1)
• C
  4% (2)
• D
  2% (1)

Explanation

Option A is correct because enterprise architecture is formally divided into four domains: business (strategy), applications, information (data), and technology - the foundational framework used in standards like TOGAF. These four layers work together to align IT capabilities with organizational goals.

Why the distractors fail:

• B is wrong because "architecture" is the overarching discipline itself, not one of its roles, and "compliance" is a governance concern, not an EA domain.
• C is wrong because "security" is a cross-cutting concern addressed within the domains, not a standalone EA role, and splitting "business" and "strategy" misrepresents the single "business strategy" domain.
• D is wrong because "risk" is a governance/management function, not one of the four EA domains.

Memory tip: Use the acronym BAIT - Business strategy, Applications, Information, Technology. Think of enterprise architecture as the "bait" that hooks your IT strategy to your business goals.
