Correct answer: The SQL Layer

The SQL Layer (or logical layer) is responsible for query parsing, authorization, optimization, and execution planning. The Connection Layer handles authentication and thread management, while the Storage Engine Layer (like InnoDB) handles actual data storage and retrieval.

Correct answer: 200, because MySQL reads configuration files in a specific order, and user-specific files (~/.my.cnf) are read last, overriding earlier settings.

MySQL reads option files in a specific sequence. On Unix/Linux, it typically reads `/etc/my.cnf`, then `/etc/mysql/my.cnf`, then `SYSCONFDIR/my.cnf`, then `$MYSQL_HOME/my.cnf`, and finally `~/.my.cnf`. Because the user-specific file is read last, any conflicting variables defined there will override the values set in the global files.
