Which statement about engine selection in watsonx.data is correct?
Select an answer to reveal the explanation.
Short Explanation
Pick the engine that fits each workload. All engines read the same governed data under the same policies, so you don't duplicate data or rewire governance.
Full Explanation
The correct statement is that engines are chosen per workload for fit, and all of them access the same governed data under the same policies. The platform separates compute from storage and governance: engines are provisioned to suit workloads, while the data and the policies over it remain shared and single.
The statement that the engine is chosen once for the platform and all workloads must use it is incorrect because a platform-wide single engine forfeits the ability to match compute to workload and creates contention.
The statement that each engine requires its own copy of the data to guarantee consistency is incorrect because consistency comes from the table format's coordinated commits, not from giving each engine its own copy.
The statement that switching engines requires governance to be reconfigured for the new engine is incorrect because policy attaches to the data and the identity, so no per-engine reconfiguration is needed.
For the exam, keep the three layers distinct: shared storage, shared governance, and workload-specific compute.
