1Z0-083 practice examsIn development
Oracle Database Administration Certified Professional
The Oracle DBA qualification proper: the container and pluggable database model and why a PDB is not an instance, provisioning by clone, plug and relocate, AutoUpgrade and the patch step people forget, then RMAN incrementals with block change tracking, the recovery cases and where RESETLOGS is required, the flashback family and its one prerequisite, and diagnosing performance through AWR, ADDM and ASH with Resource Manager above them.
What you get
Papers are cut from the bank and weighted like the real exam, and no question appears in two of them. Every wrong answer comes back on later days until you have it right.
