How does the InnoDB storage engine handle deadlocks when they are detected?

A MySQL database uses all InnoDB tables and is configured as follows;

You will be setting up a replication slave by using mysqldump. You will need a consistent backup taken from your running production server. The process should have minimal impact to active database connections.

Which two are considered good security practices when using passwords? (Choose two.)

You are setting up a new installation of MySQL Server 5.7 (a GA release.) You have used a ZIP or TAR package to ensure that the mysqld binary, along with its support files, such as plug-ins and error messages, now exist on the host. Assume that the default datadir exists on the host. You installed the binary in the default location (the default --basedirvalue) for your operating system.
Which step should you perform before defining your own databases and database tables?

On a master server that is using statement-based replication, a table of log data has become very large.
You decide to delete 100,000 rows.
