How would you use this test?

This online assessment test has a number of use cases:

• Evaluate MySQL DBAs on their understanding of MySQL administration fundamentals
• Filter out candidates for your work based on their ability to understand complex scenarios
• Make sure that candidates have real-world, practical knowledge of administering MySQL, instead of just book knowledge or having taken an administration ‘boot camp’

Which areas (chapters) will be covered in the test, and why was it chosen that way?

Database Configuration
One of the fundamental requirements for a good DBA candidate is to understand the settings for a database and how they affect the performance of a query workload, as the defaults are sometimes not appropriate in a production environment. Candidates also need to be able to choose the correct settings when creating a database to maximize its availability and manageability.

Security
Security is a hot topic in the IT industry today and is essential for a MySQL DBA to be familiar with. A strong candidate should have experience with encryption features at various levels as well as the ability to properly configure users, logins, roles, and permissions.

High Availability and Disaster Recovery
Nothing is more important than a company’s data and MySQL has a variety of technologies to aid in preserving access to the data tier when disaster strikes. Candidates should be familiar with configuring, using, and troubleshooting these features, and also how to react when data corruption happens.

Backup and Restore
One of the core tasks of a DBA is to design and implement an appropriate backup strategy that meets the downtime and data loss requirements of the application. That also means having practiced restoring from backups in a variety of scenarios and knowing how to create an optimal restore sequence when required.

Database Maintenance
Apart from performing backups, the other regular task that a DBA must perform or automate is database maintenance. A strong candidate will know why and how to implement efficient index maintenance, statistics updates, and consistency checks via mysqlcheck.

Performance Troubleshooting
Probably the most important task of a DBA is maintaining workload performance and throughput, and identifying the cause of a problem quickly. A strong candidate will know how to collect and interpret metrics from a variety of sources and use that information to zero in on the root cause of an issue. Furthermore, candidates should be able to choose an appropriate way to alleviate the problem and restore normal performance.
