What is the primary purpose of data masking in a multi-tenant CDX environment?

• A. To improve query performance.
• B. To protect sensitive data by masking fields when viewed by unauthorized tenants.
• C. To reduce data storage.
• D. To convert data types.

Answer: (B)

In a multi-tenant CDX environment, data masking is about protecting sensitive information when different tenants access the same data. It hides or obfuscates certain fields so that viewers without permission see only non-sensitive or partial values. Masking can be applied dynamically, based on who is requesting the data, or statically to stored data, so unauthorized tenants never see full details like personal identifiers or financial information. This keeps the data realistic for development and analytics while preserving privacy and meeting regulatory requirements. The other options don’t address protecting private data for unauthorized tenants—they’re about performance, storage, or data type changes, which aren’t the main goal of masking.
