What is one of the privacy mechanisms provided by Teradata?

Row Level Security (RLA) is a privacy mechanism provided by Teradata that allows for the restriction of data access at the row level based on user permissions. This means that different users can see different subsets of data within the same table, depending on their access rights. This capability is critical in environments where multiple users or groups need access to the same database but should only view data that pertains to their role or responsibilities.

For example, in a sales database, a manager might see all sales records, while a sales representative could only see records relevant to their own accounts. This enhances data privacy and security by ensuring that sensitive information is only accessible to authorized personnel.

The other options, while they provide various data security features, do not specifically focus on row-level restrictions. Node Level Security typically addresses access at the framework or infrastructure level, Column Level Security restricts access to specific fields (columns) rather than rows, and Dynamic Data Masking involves transforming sensitive data to protect it from unauthorized access but does not inherently involve user-level data segmentation like Row Level Security.
