I/O performance of the prod database on your Exadata Database Machine has degraded slightly over the past month. The database has been allocated to the OLTP I/O Resource Management (IORM) category.
Which two monitoring tools might be useful in examining I/O performance for the prod database?

• A.OS I/O metrics using Enterprise Manager host pages for the storage servers
• B.OS I/O metrics using OS tools such as iostat on the storage servers
• C.OS I/O metrics using OS tools such as iostat on the database servers
• D.I/O-specific dynamic performance views such as v$iostat_fiie, v$iostat_function, and v$iostat_consumer_group from the prod
  database instances using SQL *p1us
• E.cellcli (or exacli/exadcli) to examine storage server metrics such as database, category, ceiidisk, and griddisk
