Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Dynamic Data Masking (DDM)
Dynamic Data Masking (DDM) limits sensitive data exposure by masking it to non-privileged users in the result set of a query.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Transparent Data Encryption (TDE)
Why it's wrong here
TDE encrypts data at rest, not the query result set.
- ✗
Row-Level Security (RLS)
Why it's wrong here
RLS restricts which rows a user can see, not the content within the columns.
- ✓
Dynamic Data Masking (DDM)
Why this is correct
DDM provides a non-permanent way to obscure sensitive data for specific users.
- ✗
Always Encrypted
Why it's wrong here
Always Encrypted ensures data is encrypted in transit and at rest, requiring client-side drivers to decrypt, which is more complex than DDM.
