Which two statements are true about Oracle Data Pump export and import operations?
(Choose two.)
- A. You can detach from a data pump export job and reattach later.
- B. Data pump import requires the import file to be in a directory owned by the oracle owner.
- C. You can detach from a data pump import job and reattach later.
- D. The master table is the last object to be exported by the data pump.
- E. Data pump uses parallel execution server processes to implement parallel import.
Answer: A,E
Explanation:
B: Data Pump can employ multiple worker processes, running in parallel, to increase job performance.
D: For export jobs, the master table records the location of database objects within a dump file set. / Export builds and maintains the master table for the duration of the job. At the end of an export job, the content of the master table is written to a file in the dump file set.
/ For import jobs, the master table is loaded from the dump file set and is used to control the sequence of operations for locating objects that need to be imported into the target database.

Identify three benefits of Unified Auditing.
- A. It guarantees zero-loss auditing.
- B. The audit trail cannot be easily modified because it is read-only.
- C. It automatically audits Recovery Manager (RMAN) events.
- D. It improves overall auditing performance.
- E. Decreased use of storage to store audit trail rows in the database.
Answer: C,D,E
Explanation:
Explanation/Reference:
Explanation:
A: Starting with 12c, Oracle has unified all of the auditing types into one single unit called Unified auditing.
You don’t have to turn on or off all of the different auidting types individually and as a matter of fact auditing
is enabled by default right out of the box. The AUD$ and FGA$ tables have been replaced with one single
audit trail table. All of the audit data is now stored in Secure Files table thus improving the overall
management aspects of audit data itself.
B: Further the audit data can also be buffered solving most of the common performance related problems
seen on busy environments.
E: Unified Auditing is able to collect audit data for Fine Grained Audit, RMAN, Data Pump, Label Security,
Database Vault and Real Application Security operations.
Note:
* Benefits of the Unified Audit Trail
The benefits of a unified audit trail are many:
/(B) Overall auditing performance is greatly improved. The default mode that unified audit works is
Queued Write mode. In this mode, the audit records are batched in SGA queue and is persisted in a
periodic way. Because the audit records are written to SGA queue, there is a significant performance
improvement.
/The unified auditing functionality is always enabled and does not depend on the initialization parameters
that were used in previous releases
/(A) The audit records, including records from the SYS audit trail, for all the audited components of your
Oracle Database installation are placed in one location and in one format, rather than your having to look
in different places to find audit trails in varying formats. This consolidated view enables auditors to co-
relate audit information from different components. For example, if an error occurred during an INSERT
statement, standard auditing can indicate the error number and the SQL that was executed. Oracle
Database Vault-specific information can indicate whether this error happened because of a command rule
violation or realm violation. Note that there will be two audit records with a distinct AUDIT_TYPE. With this
unification in place, SYS audit records appear with AUDIT_TYPE set to Standard Audit.
/The management and security of the audit trail is also improved by having it in single audit trail.
/You can create named audit policies that enable you to audit the supported components listed at the
beginning of this section, as well as SYS administrative users. Furthermore, you can build conditions and
exclusions into your policies.
* Oracle Database 12c Unified Auditing enables selective and effective auditing inside the Oracle database
using policies and conditions. The new policy based syntax simplifies management of auditing within the
database and provides the ability to accelerate auditing based on conditions.
* The new architecture unifies the existing audit trails into a single audit trail, enabling simplified
management and increasing the security of audit data generated by the database.
