You upgraded from a previous Oracle database version to Oracle Database version to Oracle Database 12c. Your database supports a mixed workload. During the day, lots of insert, update, and delete operations are performed. At night, Extract, Transform, Load (ETL) and batch reporting jobs are run. The ETL jobs perform certain database operations using two or more concurrent sessions.
After the upgrade, you notice that the performance of ETL jobs has degraded. To ascertain the cause of performance degradation, you want to collect basic statistics such as the level of parallelism, total database time, and the number of I/O requests for the ETL jobs.
How do you accomplish this?

• A.Enable real-time database operation monitoring using the DBMS_SQL_MONITOR.BEGIN_OPERATION function, and then use the DBMS_SQL_MONITOR.REPORT_SQL_MONITOR function to view the required information.
• B.Enable SQL tracing for the queries in the ETL and batch reporting queries and gather diagnostic data from the trace file.
• C.Examine the Active Session History (ASH) reports for the time period of the ETL or batch reporting runs.
• D.Enable real-time SQL monitoring for ETL jobs and gather diagnostic data from the V$SQL_MONITOR view.

In your Database, the TBS PERCENT USED parameter is set to 60 and the TBS PERCENT FREE parameter is set to 20.
Which two storage-tiering actions might be automated when using information Lifecycle Management (ILM) to automate data movement?

• A.The movement of all segments to a target tablespace with a higher degree of compression,on a different storage tier, when the source tablespace exceeds TBS PERCENT USED
• B.The movement of some segments to a target tablespace with a higher degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED
• C.Setting the target tablespace to read-only
• D.The movement of some blocks to a target tablespace with a lower degree of compression, on a different storage tier, when the source tablespace exceeds TBS PERCENT USED
• E.Setting the target tablespace offline

Which three statements are true about the use of the query result cache? (Choose three.)

• A.Results may not be obtained from the query result cache, when the query_rewrite_enabled parameter is set to false.
• B.Results from remote queries may sometimes be stored in the query result cache.
• C.Stale results may still be obtained from the query result cache, if the query session's parameter is set to stale_tolerated.
  query_rewrite_integrity
• D.Results obtained from a query rewrite to a materialized view may be stored in the query result cache.
• E.Results from distributed queries are never stored in the query result cache.
• F.Results obtained from a join between a table and a view may be stored in the query result cache.

What are two of the benefits of installing Oracle Grid Infrastructure for a stand-alone server before installing and creating an Oracle database on the same server? (Choose two.)

• A.The Oracle database will be automatically registered as a resource in Oracle Restart.
• B.The Oracle database will be easier to upgrade in the future.
• C.It is the only way to have "automatic restart in place" after instance failure.
• D.The Oracle database can be created using Oracle Managed Files.
• E.The Oracle database can be created using storage managed by ASM.

You must configure Oracle Data Redaction for the EMP table to satisfy the following requirements:
- RANDOM redaction on the SAL and COMM columns
- PARTIAL redaction on the HIREDATE column
- FULL redaction on the MGR column
What would you define to implement this?

• A.one redaction policy on the table, which specifies the redaction types for all table columns that must be redacted
• B.several redaction policies, with each redaction policy specifying the redaction for table columns of that redaction type
• C.several redaction policies, with one redaction policy for each table column that must be redacted
• D.several redaction policies, with one redaction policy foe each data type defined for the table must be redacted
