BIDDL

CIDML

DTCL

Show Suggested Answer

Suggested Answer: A

The category of SQL commands that is required to revoke access to database objects is DCL. DCL, or Data Control Language, is a subset of SQL commands that are used to control or manage the access or permissions of users or roles on a database. DCL includes commands such as GRANT and REVOKE. GRANT is a DCL command that is used to grant privileges or roles to users or roles on specific objects in a database, such as tables, views, procedures, etc. REVOKE is a DCL command that is used to revoke privileges or roles from users or roles on specific objects in a database. For example, the following statement uses the REVOKE command to revoke the SELECT privilege from user Alice on table employee:

REVOKE SELECT ON employee FROM Alice;

The other options are either different categories of SQL commands or not related to SQL commands at all. For example, IDDL is not a valid acronym or category of SQL commands; IDML is not a valid acronym or category of SQL commands; TCL, or Transaction Control Language, is a subset of SQL commands that are used to control or manage transactions on a database, such as committing or rolling back changes.Reference:CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.2 Given a scenario, implement security controls for databases.

Hmm, I was debating between DCL and TCL, but I think DCL is the better choice. TCL is more for transaction control, not security and permissions.

Exactly, DCL is what you would use to grant or revoke privileges in a database.

So, DCL is more related to security and permissions while TCL is for transactions.

TCL, on the other hand, is Transaction Control Language for managing transactions.

I agree with you both. DCL makes the most sense here. The other options like IDDL, IDML, and TCL don't really seem to fit the description of the question.

Yeah, that's what I was thinking too. Revoking access to database objects is definitely a security-related operation, so it has to fall under DCL commands.

This question seems to be testing our knowledge of SQL command categories. I'm pretty sure the answer is DCL, or Data Control Language, since that's the category for commands related to security and permissions.
