Oracle Direct NFS implements NFS V3 protocol within theOracle database kernel itself. Oracle Direct NFS client overcomes many of the challenges associated with using NFS with the Oracle Database withsimple configuration, better performance than traditional NFS clients, and offers consistent configuration across platforms.QUESTION 15In your multitenant container database (CDB) containing pluggable databases (PDB), users complain about performance degradation.How does real-time Automatic database Diagnostic Monitor (ADDM) check performance degradation and provide solutions?A.It collects data from SGA and compares it with a preserved snapshot.B.It collects data from SGA, analyzes it, and provides a report.
