Question 220

Architecture peer review: A payment platform has data inconsistency because architects omitted cross-application information exchanges. Which assumption, if accepted, most directly leaves this problem unresolved?

  1. A server support group is automatically the owner of every business-facing application service.
  2. A value stream is the same thing as a sequence of technical API calls.
  3. Detailed Technology Architecture must be complete before an architecture engagement may be scoped.
  4. Every application always owns an independent copy of the authoritative enterprise data.

Explanation

Correct Answer

D:

This is precisely the false assumption to challenge for Phase C data flow. The governing principle is: Data movement and sharing must support business processes and application interactions.

Incorrect Answers

A:

This is also a risky claim, but it directly concerns Phase C app ownership rather than the error in the current case: A payment platform has data inconsistency because architects omitted cross-application information exchanges.

B:

The shortcut would be dangerous for Phase B value streams; it is not the particular misconception driving the described Phase C data flow situation.

C:

This false belief is about Phase A request scope. The central misconception is that every application always owns an independent copy of the authoritative enterprise data.

Question 221

During an architecture engagement: A transport company integrates ticketing partners without specifying ownership of fare and journey events. Which response best addresses the immediate decision?

  1. Identify critical data flows, producers, consumers, and interface information requirements.
  2. Define Data Architecture ownership, semantics, quality rules, and information exchange needs.
  3. Review the Request for Architecture Work and establish the scope, constraints, and stakeholders for Phase A.
  4. Assess the architecture change request and determine its impact and suitable response in Phase H.

Explanation

Correct Answer

A:

This directly addresses Phase C data flow. Data movement and sharing must support business processes and application interactions. A useful acceptance check is: The architecture maps key data exchanges to sources, consumers, and constraints.

Incorrect Answers

B:

This proposal belongs primarily to Phase C data ownership. It does not show that the architecture maps key data exchanges to sources, consumers, and constraints.

C:

Although relevant to Phase A request scope, this is not the most direct response to Phase C data flow. For this decision, what matters is whether the architecture maps key data exchanges to sources, consumers, and constraints.

D:

This action targets another architecture concern: Phase H change trigger. The priority here is Phase C data flow in this situation; it leaves the specific acceptance result unaddressed: the architecture maps key data exchanges to sources, consumers, and constraints.

Question 222

During design review: A transport company integrates ticketing partners without specifying ownership of fare and journey events. What is the strongest architectural reasoning for the decision?

  1. Architecture Change Management monitors change drivers and maintains architecture relevance over time.

B:

This result checks another area, Phase C data lifecycle. For This case, it does not establish that the architecture maps key data exchanges to sources, consumers, and constraints.

D:

The observation could be valid elsewhere for Phase F roadmap prioritization, but this case needs more direct Phase C data flow evidence: the architecture maps key data exchanges to sources, consumers, and constraints.

Question 224

Which flawed shortcut is most directly contradicted by the following situation? A transport company integrates ticketing partners without specifying ownership of fare and journey events.

  1. The Preliminary Phase exists primarily to design the target application portfolio.
  2. Once a project is approved, its designs never need architecture compliance checks.
  3. Requirements Management ends after the Architecture Vision is signed.
  4. Every application always owns an independent copy of the authoritative enterprise data.

Explanation

Correct Answer

D:

This is precisely the false assumption to challenge for Phase C data flow. The governing principle is: Data movement and sharing must support business processes and application interactions. This matters here because which flawed shortcut is most directly contradicted by the following situation.

Incorrect Answers

A:

This false belief is about Preliminary capability. The central misconception is that every application always owns an independent copy of the authoritative enterprise data.

B:

This is also a risky claim, but it directly concerns Phase G compliance rather than the error in the current case: A transport company integrates ticketing partners without specifying ownership of fare and journey events.

C:

The shortcut would be dangerous for Requirements management cycle; it is not the particular misconception driving the described Phase C data flow situation.

Question 225

Architecture case: A university wants a target enrollment capability but its system inventory does not show how applications cooperate. What should the architect do NEXT to resolve this concern?

  1. Model Application Architecture components, services, and their required interactions.
  2. Reconcile work-package dependencies and value delivery when determining migration sequence.
  3. Define technology security controls and trusted network paths consistent with cross-cutting architecture requirements.
