A. On a dbfs file system stored in a staging database on the Database Machine
B. On an Exadata-based ACFS file system on the Database Machine
C. On an nfs file system mounted on a database server where the external table will be accessed.
D. On local storage on one or more cells that are accessible to the database server where the load will be performed.

B. A storage server alert is only ever issued as a warning or at a critical situation.
C. Storage server alerts are all stateless alerts.
D. Storage server alerts notifications may be sent using SNMP.
E. Storage server alerts are all stateful alerts.
F. Storage server alerts notifications may be sent using SMTP.
Q35. You have used setupem.sh to deploy a plug in for Grid Control.
In which two ways do all the targets supported by the plug-in get configured?
A. The targets must be configured by an Enterprise Manager administrator manually using Grid Control.
B. Setupem.sh is used again to configure the targets.
C. The targets must be configured by an O/S administrator manually.
D. The targets must be configured by a database administrator manually.
E. There may be more than one target for each plug-in.
Q36. You are monitoring and evaluating a create index statement on your Database Machine and have run the following query after executing statement, providing the output. Shown:
Select two reasons why the statement would have produced so many “cell single block physical read” waits compared to “cell smart table scan” waits.
A. There are huge numbers of migrated rows in the table on which the index is being built.
B. There is an uncommitted transaction that has modified one block of the table on which the index is being built, in each cell.
C. Thereis a transaction that has modified one block of the table on which the index is being built in each cell, which committed after the create index began.
D. There are huge numbers of chained rows in the table on which the index is being built.
E. There is a ROWID column in the table on which the index is being built.
Q37. A table in one of your database schemas contains only varchar, number, and date data types for the columns.
Which three operations can be offloaded to the Exadata storage servers when doing a smart scan against this table, if no other situations arise that prevent Smart Scan from occurring?
