NEW QUESTION 1
Your multitenant container database (CDB) cdb1 that is running in archivelog mode contains two pluggable databases (PDBs), pdb2_1 and pdb2_2, both of which are open. RMAN is connected to the target database pdb2_1.
RMAN> BACKUP DATABASE PLUS ARCHIVELOG DELETE INPUT;
Which statement is true about the execution of this command to back up the database?

A. All data files belonging to pdb2_1 are backed up and all archive log files are deleted.
B. All data files belonging to pdb2_1 are backed up along with the archive log files.
C. Only the data files belonging to pdb2_ are backed up.
D. This command gives an error because archive log files can be backed up only when RMAN is connected to the root database.

Explanation: If you run multiple AUDIT statements on the same unified audit policy but specify different EXCEPT users, then Oracle Database uses the last exception user list, not any of the users from the preceding lists. This means the effect of the earlier AUDIT POLICY ... EXCEPT statements are overridden by the latest AUDIT POLICY ... EXCEPT statement https://docs.oracle.com/database/121/DBSEG/audit_config.htm#DBSEG459

The threshold for activating tiering policies is based on two parameters: TBS PERCENT USED
TBS PERCENT FREE
Both values can be controlled by the DBMS_ILM_ADMIN package.
TBS PERCENT USED and TBS PERCENT FREE default to 85 and 25, respectively. Hence, whenever the source tablespace’s usage percentage goes beyond 85 percent, any tiering policy specified on its
objects will be executed and objects will be moved to the target tablespace until the source tablespace becomes at least 25 percent free. Note that it is possible to add a custom condition to tiering policies to enable movement of data based on conditions other than how full the tablespace is.
In addition, the READ ONLY option must be explicitly specified for the target tablespace. 2021-04-01T21:59:00.56

Which three statements are true about the process of automatic optimization by using statistics feedback?

A. The optimizer automatically changes a plan during subsequent execution of a SQL statement if there is a huge difference in optimizer estimates and execution statistics.
B. The optimizer can CK optimize a query only once using cardinality feedback.
C. The optimizer enables monitoring for cardinality feedback after the first execution of a query.
D. The optimizer does not monitor cardinality feedback if dynamic sampling and multicolumn statistics are enabled.
E. After the optimizer identifies a query as a re-optimization candidate, statistics collected by the collectors are submitted to the optimizer.

Answer: ACD

Explanation: C: During the first execution of a SQL statement, an execution plan is generated as usual.
D: if multi-column statistics are not present for the relevant combination of columns, the optimizer can fall back on cardinality feedback.
(not B)* Cardinality feedback. This feature, enabled by default in 11.2, is intended to improve plans for repeated executions.
optimizer_dynamic_sampling optimizer_features_enable
Dynamic sampling or multi-column statistics allow the optimizer to more accurately estimate selectivity of conjunctive predicates.
Note:
* OPTIMIZER_DYNAMIC_SAMPLING controls the level of dynamic sampling performed by the optimizer.
Range of values. 0 to 10
Cardinality feedback was introduced in Oracle Database 11gR2. The purpose of this feature is to automatically improve plans for queries that are executed repeatedly, for which the optimizer does not estimate cardinalities in the plan properly. The optimizer may misestimate cardinalities for a variety of reasons, such as missing or inaccurate statistics, or complex predicates. Whatever the reason for the misestimate, cardinality feedback may be able to help.

NEW QUESTION 10
You specified the warning and critical thresholds for a locally managed tablespace to be 60% and 70%, respectively.

What could be the reason for this?

A. The event parameter was not set.
B. The sql_trace parameter is set to false.
C. Enterprise Manager was not used.
D. The statistics_level parameter is set to basic.
E. The t:kid_statistics parameter is set to fals

NEW QUESTION 12
Which three statements are true about persistent lightweight jobs?

A. A user cannot set privileges on them.
B. They generate large amounts of metadata.
C. They may be created as fully self-contained jobs.
D. They must reference an existing Scheduler Program.
E. The are useful when users need to create a large number of jobs quickl

Answer: ADE

Explanation: Unlike regular jobs, they are not schema objects. Because lightweight jobs are not schema objects, you cannot grant privileges on them. A lightweight job inherits privileges from its specified program. Thus, any user who has a certain set of privileges on the program has corresponding privileges on the lightweight job. Use lightweight jobs when you have many short-duration jobs that run frequently. Under certain circumstances, using lightweight jobs can deliver a small performance gain. A lightweight job must reference a program object (program) to specify a job action. The program must be already enabled when the lightweight job is created, and the program type must be either ‘PLSQL_BLOCK’ or ‘STORED_PROCEDURE’.

NEW QUESTION 13
Examine the command and its output: SQL> DROP TABLE EMPLOYEE;
SQL> SELECT object_name AS recycle_name, original_name, type FROM recyclebin; RECYCLE_NAMEORIGINAL_NAMETYPE
--------------------------------------------------------------------------------------------------------------
binsgk31sj/3akk5hg3j21kl5j3d==$0EMPLOYEE TABLE
You then successfully execute the command:
SQL> FLASHBACK TABLE "BINSgk31sj/3akk5hg3j21kl5j3d==$0" TO BEFORE DROP;
Which two statements are true?

A. It flashes back the employee table and all the constraints associated with the table.
B. It automatically flashes back all the indexes on the employes table.
C. It automatically flashes back any triggers defined on the table.
D. It flashes back only the structure of the table and not the data.
E. It flashes back the data from the recycle bin and the existing data in the original table is permanently lost.

Answer: BC

Explanation: A table and all of its dependent objects (indexes, LOB segments, nested tables, triggers, constraints and so on) go into the recycle bin together, when you drop the table. Likewise, when you perform Flashback Drop, the objects are generally all retrieved together. Trigger automatically flashbacked. http://docs.oracle.com/cd/B19306_01/backup.102/b14192/flashptr004.htm#i1020594

NEW QUESTION 14

NEW QUESTION 16
You have set the value of the NLS_TIMESTAMP_TZ_FORMAT parameter to YYYY-MM-DD. The default
format of which two data types would be affected by this setting?

A. DATE
B. TIMESTAMP
C. INTERVAL YEAR TO MONTH
D. INTERVAL DAY TO SECOND
E. TIMESTAMP WITH LOCAL TIME ZONE

Answer: BE

NEW QUESTION 17
In a database supporting an OLTP workload, tables are frequently updated on both key and nonkeycolumns. Reports are also generated by joining multiple tables.
Which table organization or type would provide the best performance for this hybrid workload?

A. heap table with a primary key index
B. external table
C. hash clustered table
D. global temporary table
E. index clustered table

Answer: E

Explanation: Do not cluster tables if the application joins them only occasionally or modifies their common column values frequently. Modifying a row’s cluster key value takes longer than modifying the value in an unclustered table, because Oracle might need to migrate the modified row to another block to maintain the cluster.
