A team asks for a new customer service that differs only slightly from an existing enterprise service. What does Chapter 8 recommend?
A. Always create a new service to avoid change.
B. Build a direct database connection.
C. Prefer reuse or modification of the existing service when feasible to avoid service proliferation/support complexity.

Which structures should be modeled in DII?
A. Only persistent warehouses.
B. Only source databases.

Why does Chapter 8 warn that data migration is not really a one-time process?
A. Because it should never be tested.
B. Because migrations are executed repeatedly through testing phases and final implementation, and require full integration analysis/design.
C. Because all migration must be synchronous.
D. Because migrated data requires no transformation.

A real-time DII service feeds the organization's most critical application. At what service level should the integration be monitored/serviced?
A. At the service level of the most demanding dependent target/consumer.
B. At the lowest service level in the portfolio.
C. Only during project testing.
D. Only when a user reports a failure.
DII8-050 · Tools & Implementation · Standard · Understand
Why must DII Metadata be maintained after implementation?
A. Because Metadata is only a temporary project artifact.
B. Because structures, meanings, mappings, transformation rules, processing history and service catalogs must remain reliable for operations, risk management and future change.
C. Because maintaining Metadata eliminates the need for monitoring.
D. Because Metadata replaces source systems.

Which statement about a data virtualization server is correct?
A. It is always a physical ETL staging database.
B. It replaces every data warehouse by definition.
C. It can integrate data virtually across heterogeneous sources, but it does not automatically replace the warehouse in enterprise architecture.

What implementation mistake does Chapter 8 warn against when launching an enterprise integration program?
A. Replacing every working local integration solely for uniformity instead of focusing on business value and unmet integration needs.
B. Including business-oriented participants.
C. Using enterprise sponsorship.
D. Reusing standard tools where appropriate.

A. Only developer headcount.
B. Only storage capacity.
C. Only the number of canonical-model fields.
D. Data availability; data volumes and speed/latency; and solution costs/complexity including ease of acquiring new data and systems using integration solutions.
