What UID is referenced for the Red Hat provided MySQL service in this setup?

• A. 0
• B. 501
• C. 27
• D. 1000

Answer: (C)

The service runs under the dedicated system account for MySQL, which on Red Hat images is assigned the UID 27. Using this fixed, non-root user restricts privileges to what the database needs and aligns with how the MySQL files (like data and logs) are owned. Root is 0, and IDs like 501 or 1000 are typically used for human users, not for running system services, so they aren’t used for the MySQL process. This is why the referenced UID is 27.
