Role-Based Access Control (RBAC) Quiz

What is the purpose of the 'users' table in the RBAC system?

• To store privilege information

• To store user information

• To store user roles

• To store role information

Answer explanation

The 'users' table in the RBAC system is designed to store user information, including details like usernames and identifiers. This is essential for managing user access and roles effectively.

Which SQL statement is used to grant privileges to roles?

• INSERT

• SELECT

• GRANT

• UPDATE

Answer explanation

The correct SQL statement to grant privileges to roles is 'GRANT'. This command allows database administrators to assign specific permissions to users or roles, unlike INSERT, SELECT, or UPDATE, which are used for data manipulation.

What type of information does the 'roles' table contain?

• User IDs

• Role names

• User passwords

• Privilege IDs

Answer explanation

The 'roles' table contains role names, which define the different roles users can have in a system. User IDs and passwords are typically found in a 'users' table, while privilege IDs relate to access levels, not roles.

Which of the following is NOT a privilege mentioned in the text?

• DELETE

• EXECUTE

• SELECT

• UPDATE

Answer explanation

The privilege 'EXECUTE' is not mentioned in the text, while 'DELETE', 'SELECT', and 'UPDATE' are. Therefore, 'EXECUTE' is the correct answer as it does not belong to the list of privileges.

What is the relationship between 'user_roles' and 'users'?

• Users can have multiple roles

• Roles can have multiple users

• Roles are independent of users

• Users cannot have roles

Answer explanation

The correct choice is 'Users can have multiple roles' because in many systems, a user can be assigned various roles, allowing for flexible permissions and access control.

Which role is NOT mentioned as an example in the text?

• supervisor

• manager

• employee

• admin

Answer explanation

The text does not mention 'supervisor' as an example role, while 'manager', 'employee', and 'admin' are explicitly listed. Therefore, 'supervisor' is the correct answer.

What is the primary function of the 'privileges' table?

• To store user information

• To store privilege names

• To store role information

• To store user roles

Answer explanation

The 'privileges' table primarily stores privilege names, which define the specific rights or permissions that can be granted to users or roles. This distinguishes it from tables that store user or role information.

What is the first task in implementing the RBAC system?

• Assign users to roles

• Grant privileges to roles

• Create a database

• Create roles and privileges

Answer explanation

The first task in implementing an RBAC system is to create a database. This foundational step allows for the storage of roles, users, and privileges, which are essential for the subsequent tasks of assigning users and granting privileges.

What is the purpose of the 'role_privileges' table?

• To store role names

• To store user information

• To link roles to privileges

• To link users to roles

Answer explanation

The 'role_privileges' table is designed to link roles to privileges, defining what actions each role can perform. This is crucial for managing access control in a system.

Which of the following is a task related to testing the RBAC system?

• Define roles and privileges

• Assign users to roles

• Create test cases

• Create a database schema

Answer explanation

Creating test cases is essential for validating the functionality of the RBAC system. It ensures that roles and privileges are correctly enforced, making it a key task in testing.
