The Open Group OGEA-103 Practice Test 78
Question 770
An architect is asked to explain the following situation: A security regulation changes during a long migration, and architects must decide whether to revise individual views or begin a substantial new architecture cycle. Which underlying principle is most relevant?
- The architecture repository, Architecture Landscape, and reuse mechanisms support parallel ADM work if ownership and consistency are governed.
- Architecture Change Management keeps architectures relevant by assessing change drivers and the scale of impact.
- Phase G ensures delivery conforms to architecture decisions or has an accountable, approved exception.
- Phase A establishes purpose, stakeholder alignment, high-level target and authorization before committing to detailed designs.
Explanation
Correct Answer
B:This principle addresses Change classification response. The preferred action is: Assess change impact and classify the appropriate incremental, maintenance, or major architecture response under Phase H. Verify: The change record identifies affected baselines, required iteration, risks, and the approving authority.
Incorrect Answers
A:This is a legitimate concept for Reference assets and architecture partitions; it does not most directly account for A security regulation changes during a long migration, and architects must decide whether to revise individual views or begin a substantial new architecture cycle. The important distinction is that architecture Change Management keeps architectures relevant by assessing change drivers and the scale of impact.
C:That principle helps reason about Architecture implementation governance, but the described concern is specifically governed by Change classification response. It does not explain architecture Change Management keeps architectures relevant by assessing change drivers and the scale of impact.
D:This is a legitimate concept for Vision sponsorship and scope; it does not most directly account for A security regulation changes during a long migration, and architects must decide whether to revise individual views or begin a substantial new architecture cycle. The important distinction is that architecture Change Management keeps architectures relevant by assessing change drivers and the scale of impact.
Question 771
Architecture acceptance review: A security regulation changes during a long migration, and architects must decide whether to revise individual views or begin a substantial new architecture cycle. Which evidence would BEST demonstrate that this concern was resolved?
- The roadmap places enabling capabilities before dependent releases and identifies a controlled intermediate state.
- Strategy, investment, risk, and implementation bodies share accountable handoffs and a traceable architecture roadmap.
- The change record identifies affected baselines, required iteration, risks, and the approving authority.
- Service ownership, interactions, and unresolved integration gaps are documented for migration planning.
Explanation
Correct Answer
C:This checks the Change classification response outcome. The related decision is: Assess change impact and classify the appropriate incremental, maintenance, or major architecture response under Phase H.
Incorrect Answers
A:This result checks another area, Delivery work package sequencing. For This case, it does not establish that the change record identifies affected baselines, required iteration, risks, and the approving authority.
B:This would provide assurance for Strategic operating change, not the stated issue. It does not show the change record identifies affected baselines, required iteration, risks, and the approving authority.
D:This result checks another area, Application integration development. For This case, it does not establish that the change record identifies affected baselines, required iteration, risks, and the approving authority.
Question 772
Architecture peer review: A security regulation changes during a long migration, and architects must decide whether to revise individual views or begin a substantial new architecture cycle. Which assumption, if accepted, most directly leaves this problem unresolved?
- Security can safely be deferred to infrastructure engineering after the architecture is fully approved.
- The architect must select the preferred application vendor before asking sponsors about scope or outcomes.
- Infrastructure architecture is sufficient evidence of a feasible business operating model.
- Every change is automatically minor if a deployment team can implement it in one sprint.
Explanation
Correct Answer
D:This is precisely the false assumption to challenge for Change classification response. The governing principle is: Architecture Change Management keeps architectures relevant by assessing change drivers and the scale of impact.
Incorrect Answers
A:This is also a risky claim, but it directly concerns Risk and security in Vision rather than the error in the current case: A security regulation changes during a long migration, and architects must decide whether to revise individual views or begin a substantial new architecture cycle.
B:The shortcut would be dangerous for Vision sponsorship and scope; it is not the particular misconception driving the described Change classification response situation.
C:This false belief is about Business versus technology sequencing. The central misconception is that every change is automatically minor if a deployment team can implement it in one sprint.
Question 773
Architecture case: A cloud service acquisition alters strategy and multiple capability boundaries after target architecture approval; project staff call it a routine configuration change. What should the architect do NEXT to resolve this concern?
- Assess change impact and classify the appropriate incremental, maintenance, or major architecture response under Phase H.
- Map stakeholders and concerns, tailor relevant views, and agree a structured engagement and decision process.
- Create lean enterprise architecture guardrails and iteration checkpoints that support autonomous product delivery.
- Use an Architecture Contract, scheduled compliance reviews, and controlled dispensation decisions for implementation.

Question 777
Consider this enterprise-change situation: During a data architecture iteration, a healthcare regulator adds a retention obligation that impacts previously approved application interfaces. What is the most appropriate architecture action?
- Baseline the changed requirement, assess impacts across prior/current ADM phases, and update the Requirements Repository.
- Clarify architecture scope and sponsoring authority, develop the Architecture Vision, and secure an approved Statement of Architecture Work.
- Map stakeholders and concerns, tailor relevant views, and agree a structured engagement and decision process.
- Capture material security, risk, and regulatory concerns in Phase A and state how subsequent architecture work will address them.
Explanation
Correct Answer
A:This directly addresses Requirements traceability in iteration. Requirements Management is continuous and manages change and conflict across the architecture cycle. A useful acceptance check is: The requirement has an owner, changed baseline, documented impact, and tracked downstream design actions.
Incorrect Answers
B:This proposal belongs primarily to Vision sponsorship and scope. It does not show that the requirement has an owner, changed baseline, documented impact, and tracked downstream design actions.
C:Although relevant to Executive versus operations concerns, this is not the most direct response to Requirements traceability in iteration. For this decision, what matters is whether the requirement has an owner, changed baseline, documented impact, and tracked downstream design actions.
D:This action targets another architecture concern: Risk and security in Vision. The priority here is Requirements traceability in iteration in this situation (During a data architecture iteration, a healthcare regulator adds a retention obligation that impacts previously approved application interfaces); it leaves the specific acceptance result unaddressed: the requirement has an owner, changed baseline, documented impact, and tracked downstream design actions.
