Quick Answer
The answer is the `db_datareader` fixed database role. This role is the correct choice because it grants read-only permission to all user tables within a database, including those in the 'sales' schema, without allowing any data modifications or schema changes. For the Microsoft Azure Data Engineer Associate DP-203 exam, this scenario tests your understanding of granular database-level permissions versus server-level roles; a common trap is confusing `db_datareader` with `db_owner` or `db_datawriter`, which would grant excessive privileges. The exam often presents this as a straightforward security requirement where data scientists need SELECT-only access, and `db_datareader` is the precise, built-in solution. Remember the memory tip: "Reader is for SELECT only—if they can read, they cannot write."
This DP-203 practice question tests your understanding of design and implement data security. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A company uses Azure Synapse Analytics with a dedicated SQL pool. They need to ensure that a team of data scientists can query all tables in the 'sales' schema but cannot modify any data or schema objects. Which role should the team be assigned?
db_owner
Why wrong: db_owner has full control over the database.
db_datareader
db_datareader grants read access to all tables.
db_ddladmin
Why wrong: db_ddladmin allows schema modifications.
db_datawriter
Why wrong: db_datawriter allows insert, update, delete operations.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
db_datareader
The `db_datareader` role grants read-only access to all user tables in a database, allowing the team to query all tables in the 'sales' schema without the ability to modify data or schema objects. This aligns perfectly with the requirement for data scientists to perform SELECT queries only.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
db_owner
Why it's wrong here
db_owner has full control over the database.
db_datareader
Why this is correct
db_datareader grants read access to all tables.

db_ddladmin
Why it's wrong here
db_ddladmin allows schema modifications.
db_datawriter
Why it's wrong here
db_datawriter allows insert, update, delete operations.
Common exam traps
The trap here is that candidates often confuse `db_datareader` with `db_datawriter` or assume `db_ddladmin` is required for querying, not realizing that read-only access is specifically granted by `db_datareader` without any write or schema modification capabilities.
Detailed technical explanation
In Azure Synapse Analytics dedicated SQL pools, `db_datareader` is a fixed database role that maps to the `SELECT` permission on all user tables and views, but does not include permissions on system objects or the ability to execute DDL. This role is ideal for read-only workloads like data exploration or reporting, and can be combined with schema-level permissions if finer granularity is needed.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
