• A.The virtual size of a sparse griddisk may exceed the physical size of the space occupied by the griddisk.
• B.Additional space for a sparse griddisk is allocated as soon as newly written data is stored in the flashcache on a cell.
• C.Sparse diskgroups may be created using a combination of sparse and non-sparse griddisks.
• D.Sparse diskgroups may not be used for database snapshots.
• E.Sparse diskgroups must be created using sparse griddisks.

Examine this IORM plan:

Which two are true concerning this plan?

• A.If I/Os come from the HR database only, then they may get up to 10% of the I/O bandwidth on the cell.
• B.If I/Os come from the HR database only, then they may get up to 100% of the I/O bandwidth on the cell.
• C.I/Os from the finance database are guaranteed to get a minimum of 45% of the I/O bandwidth if the demand exists, and a maximum of 60% of the I/O bandwidth even if no other databases are doing I/O to the cell, and the demand from the finance database exceeds 60% of the maximum I/O rate of the cell.
• D.I/Os from the finance database are guaranteed to get 45% of the I/O bandwidth if the demand is at least 60% of the maximum I/O rate of the cell, but may get 100% of the I/O bandwidth if no other databases are performing I/O to the cell.
• E.The Finance database can use at least 45%, but never more than 60%, of the total Flash Cache capacity.

• B.ACFS supports file system snapshots.
• C.Storage Area Network (SAN) -based file systems may be accessed directly from the storage servers in a database machine.
• D.ACFS uses storage in a database on the database machine
• E.DBFS supports file system snapshots.

Which three statements are true concerning the configuration of SNMP on an Exadata x5 or x6 Database Machine?

• B.Some SNMP notifications from a storage server ILOM are sent directly to the management server (MS) process on the same storage servers.
• C.The Database Machine internal Cisco Switch communicates directly with the Enterprise Manager agent via SNMP.
• D.All SNMP notifications from the storage server ILOMs are sent directly to the Automatic Service Request (ASR) manager.
• E.Some SNMP notifications may be configured using the alter cell command on the storage servers.
• F.All SNMP notifications from a database server ILOM are sent directly to the management server (MS) process on the same database server.
