With only MyISAM tables, how many of the following are for use?

mysql, mysqladmin, mysqldump, mysqlisamchk

This question is asking about tools that work with MySQL.
MyISAM is a type of table storage engine used by MySQL.
Let's break down the options:
* mysql: This is the interactive command-line client used for interacting directly with MySQL. It works with all types of tables, including MyISAM.
* mysqladmin: This is a tool for administrative tasks like managing users, starting and stopping the MySQL server, and checking status. It works with all table types, including MyISAM.
* mysqldump: This is used to create backups of your MySQL database. It works with all types of tables, including MyISAM.
* mysqlisamchk: This is a utility specifically for MyISAM tables. It's used for checking and repairing MyISAM table files.
Answer: The correct answer is D: 4 because all four tools can be used with MyISAM tables.
