NO.120 Which two are true about the Oracle database methodology? (Choose two.)

The Oracle Database time model should be used to find the database and instance areas most in need of tuning.

Tuning activities should stop once the user is satisfied with performance.

Tuning activities should stop once agreed service levels for performance have been met.

The database instance memory should always be tuned before tuning any file systems.

The statistics_level parameter is set to all when any of the PDBs is reopened.

The statistics_level parameter is set to all only for PDB2 when it is reopened.

The statistics_level parameter is set to all when the root database is restarted.

The statement is ignored because there is no SPFILE for a PDB.
