The Open Group OGEA-103 Practice Test 26
Question 250
During design review: A multinational proposes incompatible hosting technologies for the same shared nonfunctional requirement. What is the strongest architectural reasoning for the decision?
- Data movement and sharing must support business processes and application interactions.
- Phase D defines technology services and infrastructure needed to support the target application and data architectures.
- Technology design must demonstrate how infrastructure capabilities satisfy nonfunctional architecture requirements.
- Architecture Change Management monitors change drivers and maintains architecture relevance over time.
Explanation
Correct Answer
B:This principle addresses Phase D platform standards. The preferred action is: Develop a Target Technology Architecture with platform services and standard constraints for the intended workloads. Verify: Target technology choices trace to application requirements and approved standards.
Incorrect Answers
A:That principle helps reason about Phase C data flow, but the described concern is specifically governed by Phase D platform standards. It does not explain phase D defines technology services and infrastructure needed to support the target application and data architectures.
C:The statement addresses Phase D resilience. In the present case, a principle for Phase D platform standards is required: phase D defines technology services and infrastructure needed to support the target application and data architectures.
D:That principle helps reason about Phase H change trigger, but the described concern is specifically governed by Phase D platform standards. It does not explain phase D defines technology services and infrastructure needed to support the target application and data architectures.
Question 251
Following the proposed architecture change: A multinational proposes incompatible hosting technologies for the same shared nonfunctional requirement. Which outcome should be verified?
- Every unsupported or redundant application service has a target disposition.
- Changed requirements connect to impacted architecture views, decisions, and responsible owners.
- Target technology choices trace to application requirements and approved standards.
- Application collaboration and service interfaces trace to business capabilities.
Explanation
Correct Answer
C:This checks the Phase D platform standards outcome. The related decision is: Develop a Target Technology Architecture with platform services and standard constraints for the intended workloads.
Incorrect Answers
A:The observation could be valid elsewhere for Phase C app gaps, but this case needs more direct Phase D platform standards evidence: target technology choices trace to application requirements and approved standards.
B:This result checks another area, Requirements management cycle. For This case, it does not establish that target technology choices trace to application requirements and approved standards.
D:The observation could be valid elsewhere for Phase C application collaboration, but this case needs more direct Phase D platform standards evidence: target technology choices trace to application requirements and approved standards.
Question 252
Architecture peer review: A multinational proposes incompatible hosting technologies for the same shared nonfunctional requirement. Which assumption, if accepted, most directly leaves this problem unresolved?
- Data retention obligations can be delegated entirely to network-topology diagrams.
- Once a project is approved, its designs never need architecture compliance checks.
- Security architecture is only a concern of Phase H, after deployment.
- Phase D should be completed before business outcomes have been considered.
Explanation
Correct Answer
D:This is precisely the false assumption to challenge for Phase D platform standards. The governing principle is: Phase D defines technology services and infrastructure needed to support the target application and data architectures.
Incorrect Answers
A:This false belief is about Phase C data lifecycle. The central misconception is that phase D should be completed before business outcomes have been considered.
B:This is also a risky claim, but it directly concerns Phase G compliance rather than the error in the current case: A multinational proposes incompatible hosting technologies for the same shared nonfunctional requirement.
C:The shortcut would be dangerous for Phase D network trust; it is not the particular misconception driving the described Phase D platform standards situation.
Question 253
Architecture case: An infrastructure team selects a novel platform without checking enterprise technology standards. What should the architect do NEXT to resolve this concern?

- Model business value streams and connect value stages to the capabilities enabling them.
- Review the Request for Architecture Work and establish the scope, constraints, and stakeholders for Phase A.
