The answer is that the database user must have a default schema, along with the ability to issue GRANT statements on specific columns and a table with the columns already defined. This is correct because column-level security prerequisites in Azure Synapse dedicated SQL pool rely on the native SQL Server permission model: you use GRANT SELECT on individual columns to restrict access, and a default schema ensures the user can resolve object names without ambiguity when querying. On the Microsoft Azure Data Engineer Associate DP-203 exam, this concept tests your understanding of granular access control without requiring views or application changes. A common trap is assuming you need a separate schema or role membership for each column, but the key is that the GRANT itself is the mechanism—no schema modification is required beyond the user’s default schema. Remember the mnemonic “Default, Grant, Table” to recall the three prerequisites: a default schema, the ability to grant on columns, and an existing table structure.
DP-203 Design and implement data security Practice Question
This DP-203 practice question tests your understanding of design and implement data security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE of the following are required to implement column-level security in Azure Synapse Analytics dedicated SQL pool?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A GRANT statement on specific columns to users or roles
Option A is correct because column-level security in Azure Synapse Analytics dedicated SQL pool is implemented using GRANT statements on specific columns. By granting SELECT on only certain columns to a user or role, you restrict access to sensitive data at the column level without needing to create views or modify schemas. This is the native mechanism provided by SQL Server and Azure Synapse for column-level security.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
A GRANT statement on specific columns to users or roles
Why this is correct
GRANT allows access to specified columns.

✗
A VIEW that selects only the allowed columns
Why it's wrong here
A VIEW is an alternative method but not required for column-level security.
✗
A DENY statement on specific columns to users or roles
Why it's wrong here
DENY is not required; absence of GRANT is enough to block access.
✗
A row-level security policy must be in place
Why it's wrong here
RLS is for rows, not columns.
✓
The database user must have a default schema
Why this is correct
A default schema is required for the user to access objects.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse column-level security with row-level security or assume that DENY statements can be used at the column level, but Azure Synapse only supports GRANT for column-level permissions and does not support DENY on individual columns.
Detailed technical explanation
How to think about this question
Column-level security in Azure Synapse is implemented by granting SELECT on specific columns using the syntax `GRANT SELECT ON OBJECT::TableName(Column1, Column2) TO UserOrRole`. Under the hood, this creates a security descriptor at the column level that is evaluated during query compilation, and if a user lacks SELECT on a column, they receive a permission error. A real-world scenario is a financial table where account numbers are sensitive; you can grant SELECT on all columns except the account number to analysts, while granting full access to auditors.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
