Enterprise Architecture and IT Integration Flashcards

The TOGAF Architecture Development Method (ADM) is BEST described as:

Answer: An iterative cycle for developing and managing enterprise architecture

TOGAF ADM is an iterative, phased cycle that guides organizations through developing, implementing, and continually refining their enterprise architecture.

Which enterprise architecture domain governs the technical infrastructure that supports IT applications?

Answer: Technology Architecture

Technology Architecture covers the hardware, network, and infrastructure components that host and support business applications.

A governance 'architecture principle' MOST effectively guides IT decision-making by:

Answer: Providing a stable rule that all IT decisions must respect regardless of project context

Architecture principles are enduring rules — like 'prefer reuse over rebuild' — that govern all IT decisions consistently, ensuring coherence across the enterprise.

When legacy system replacement is being considered, enterprise architecture governance MOST helps by:

Answer: Assessing dependencies, integration impacts, and alignment with the target architecture before a decision is made

EA governance ensures replacement decisions are informed by a clear understanding of system dependencies, integration requirements, and future architectural direction.

In CGEIT, an enterprise architecture gap analysis PRIMARILY identifies:

Answer: The differences between current IT capabilities and what is needed to achieve future business goals

A gap analysis compares the current IT capability state to the future target state required by business strategy, identifying what must be built, changed, or retired.

An organization's IT governance committee approves a new enterprise application without an architecture review. The MOST likely consequence is:

Answer: Integration conflicts, data duplication, and misalignment with the existing IT estate

Skipping architecture review risks introducing systems that conflict with existing integrations, duplicate data, and undermine the coherence of the enterprise IT estate.
