A global financial institution is implementing data masking technology to protect personal data used for testing purposes in non-production environments. Which of the following is the GREATEST…

Question

Options

• AAccess to personal data is not strictly controlled in development and testing environments.
• BComplex relationships within and across systems must be retained for testing.
• CPersonal data across the various interconnected systems cannot be easily identified.
• DData masking tools are complex and difficult to implement.

• A
  13% (8)
• B
  53% (32)
• C
  7% (4)
• D
  27% (16)

Explanation

Effective data masking must preserve referential integrity-the logical relationships between records and across interconnected systems-so that masked data remains functionally valid for testing. For example, if a customer ID is masked, that same masked value must be consistently applied everywhere that ID appears across all related tables and systems. Breaking these relationships renders the test data unusable. While access controls (A) and tool complexity (D) are real concerns, they are manageable. Identifying personal data (C) is addressed by data discovery tools. Maintaining consistent relational integrity across a complex financial institution's ecosystem is the most technically difficult challenge.
