A regional transit consortium will share anonymized ridership aggregates with external partners. What Unity Catalog naming consideration matters most when creating the catalog?

When a regional transit consortium will share anonymized ridership aggregates with external partners, the Unity Catalog naming consideration that matters most is choosing catalog naming aligned to controlled external-sharing so shared ridership products are clearly separated from internal-only catalogs. Clear catalog boundaries reduce mistaken shares of internal bronze/PII datasets and make Delta Sharing / external recipient grants easier to reason about for multi-agency governance.

Naming the catalog after a temporary laptop hostname so partners can SSH to the driver misunderstands sharing (partners receive governed data shares, not SSH to drivers) and creates unstable, non-governable names. Hiding all names and sharing raw bronze PII under a generic misc catalog violates anonymization intent and least privilege. Using identical names for internal PHI catalogs and external share catalogs to “reduce documentation” maximizes confusion and mis-share risk across agencies.

Exam caveat: Delta Sharing shares schemas/tables from UC; catalog design should make shareable gold/aggregate products obvious versus internal-only zones. Anonymized aggregates still need contractual and technical controls—naming alone is insufficient but is what this stem asks. Do not put partner-facing shares in catalogs that also hold unrestricted PII “for convenience.”

Operational check: create a distinctly named external-share or partner catalog for anonymized ridership products, keep internal operational catalogs separate, grant share recipients only on approved objects, and review share inventory before each partner onboarding.
