During a design review, an architect asks which choice best matches the IBM guidance. For IBM Certified watsonx Data Lakehouse Engineer, the topic is SQL troubleshooting. What should the team do?
Select an answer to reveal the explanation.
Short Explanation and Infographic
In watsonx.data, query troubleshooting follows a structured approach: verify SQL syntax against the schema, confirm the user has the required catalog permissions, check that the data source (catalog registration, remote connection) is reachable, and confirm the query engine is running and has available resources. Each failure mode produces distinct error signals, and the Query Workspace's execution history surfaces them with timestamps. Random debugging without a framework wastes time and misses root causes.

Full Explanation
The correct answer is option D: Check syntax, permissions, source availability, and engine selection when queries fail.. This aligns with IBM's Data consumption and analytics guidance, which emphasizes check syntax, permissions, source availability, and engine selection when queries fail as the recommended approach for production deployments. Option A (Assume every failed query means data loss) is incorrect because it either bypasses IBM's recommended architecture or introduces operational risk that the correct approach is specifically designed to avoid. Option B (Increase storage capacity before reading the error) is incorrect because it either bypasses IBM's recommended architecture or introduces operational risk that the correct approach is specifically designed to avoid. Option C (Change dashboard colors to refresh metadata) is incorrect because it either bypasses IBM's recommended architecture or introduces operational risk that the correct approach is specifically designed to avoid. Understanding this distinction is critical for the C9007300 exam: IBM watsonx.data is designed to enforce governance, performance, and operational best practices through its built-in architecture, and the correct answers consistently reflect those architectural constraints rather than shortcut alternatives.
