Expert take: what Oracle DBA OCA really tests

The Oracle Database SQL Certified Associate (1Z0-071) is a pure SQL exam, and it is precise about Oracle behaviour — implicit conversions, NULL handling, the DUAL table and Oracle-specific functions trip up candidates who only know generic SQL. With 63 questions and a 63% bar, and because the credential does not expire, it is a durable foundation best built by actually writing queries against a real Oracle database rather than memorising syntax.
