Which statement best summarises query troubleshooting in watsonx.data?
Select an answer to reveal the explanation.
Short Explanation
Start with the recorded error and check syntax, permissions, source availability, and engine selection. Don't change infrastructure until the evidence points there. That evidence-first order is what this objective wants you to show.
Full Explanation
Effective troubleshooting is evidence-driven: the recorded error names the failure class, and the four common causes—malformed SQL, missing entitlement, an unavailable source, and an engine lacking a needed capability—account for most cases. Infrastructure changes come last, once the evidence justifies them. The option that says to apply standard remediation by resizing the engine is incorrect because capacity is not the usual cause, and reflexive resizing spends money without fixing typos or missing grants. The option that says to escalate every failure to source system owners is incorrect because most failures are local to the statement or its permissions; blanket escalation wastes another team's time. The option that says to rebuild the affected tables is incorrect because rebuilding tables is a heavyweight action on an unfounded assumption about metadata. For the exam, recite the checklist and the principle that evidence precedes change.
