Which of the following is NOT a benefit of using managed SQL databases?

The selection of "full control over server configuration" as the correct answer highlights a key characteristic of managed SQL databases. When utilizing a managed database service, users typically receive many automated features designed to simplify database management. These features include automated backups, reduced administrative burdens, and automated patching, which are designed to enhance efficiency and help organizations focus on other tasks rather than maintenance.

In contrast, managed services often come with restrictions on direct server access and configuration. This means that when using a managed SQL database, users do not have the same level of fine-tuned control over server settings and configurations that they would have if they were managing the database themselves on on-premises hardware. The intent is to allow users to benefit from the service provider's expertise and to streamline processes, but this often results in less customization regarding server configurations. Thus, choosing to prioritize automated and convenient features inherently limits the level of control the user has over those configurations.
