Additionally,

This is season to become SQL DBA.

I believe, for being a Professional SQL DBA, all we need to learn from DBA related learning websites and practice.... eg. https://learn.microsoft.com/.

Usual Causes for not getting latest Certification.

- Odd Office Hours.

- Busy Schedule.

- Far away from Examination Centre.

Initially, we can start from Backup and Restore, Azure Basics, Different Type of Joins, Managed Services, Basics of HA, All Basic commands, Performance Monitoring. 

For Current Verson, please execute 'select @@version' in query analyser.
