QUESTION NO: 1
You notice a high number of waits for the db file scattered read and db file sequential read events in the recent Automatic Database Diagnostic Monitor (ADDM) report. After further investigation, you find that queries are performing too many full table scans and indexes are not being used even though the filter columns are indexed.
Identify three possible reasons for this. (Choose three.)
A. Undersized shared pool
B. Missing or stale histogram statistics
C. High value for the DB_FILE_MULTIBLOCK_READ_COUNT parameter
D. High clustering factor for the indexes
E. Oversized buffer cache
Answer: B,C,D
Explanation
D: DB_FILE_MULTIBLOCK_READ_COUNT is one of the parameters you can use to minimize I/O during table scans. It specifies the maximum number of blocks read in one I/O operation during a sequential scan.
The total number of I/Os needed to perform a full table scan depends on such factors as the size of the table, the multiblock read count, and whether parallel execution is being utilized for the operation.
QUESTION NO: 2
You execute the following piece of code with appropriate privileges:
User SCOTT has been granted the CREATE SESSION privilege and the MGR role.
Which two statements are true when a session logged in as SCOTT queries the SAL column in the view and the table? (Choose two.)
A. Data is redacted for the EMP.SAL column only if the SCOTT session does not have the MGR role set.
B. Data is never redacted for the EMP_V.SAL column.
C. Data is redacted for EMP.SAL column only if the SCOTT session has the MGR role set.
D. Data is redacted for the EMP_V.SAL column only if the SCOTT session has the MGR role set.
E. Data is redacted for the EMP_V.SAL column only if the SCOTT session does not have the MGR role set.
Answer: A,B
Explanation
Note:
* DBMS_REDACT.FULL completely redacts the column data.
* DBMS_REDACT.NONE applies no redaction on the column data. Use this function for development testing purposes. LOB columns are not supported.
* The DBMS_REDACT package provides an interface to Oracle Data Redaction, which enables you to mask (redact) data that is returned from queries issued by low-privileged users or an application.
* If you create a view chain (that is, a view based on another view), then the Data Redaction policy also applies throughout this view chain. The policies remain in effect all of the way up through this view chain, but if another policy is created for one of these views, then for the columns affected in the subsequent views, this new policy takes precedence.
QUESTION NO: 3
Your multitenant container database, CDB1, is running in ARCHIVELOG mode and has two pluggable databases, HR_PDB and ACCOUNTS_PDB. An RMAN backup exists for the database.
You issue the command to open ACCOUNTS_PDB and find that the USERDATA.DBF data file for the default permanent tablespace USERDATA belonging to ACCOUNTS_PDB is corrupted.
What should you do before executing the commands to restore and recover the data file in
ACCOUNTS_PDB?
A. Issue the ALTER PLUGGABLE DATABASE accounts_pdb OPEN RESTRICTED command.
B. Place CDB1 in the mount stage and then take the USERDATA tablespace offline in ACCOUNTS_PDB
.
C. Place CDB1 in the mount stage and issue the ALTER PLUGGABLE DATABASE accounts_pdb CLOSE
IMMEDIATE command.
D. Take the USERDATA tablespace offline in ACCOUNTS_PD
Answer: D
Explanation
* You can take an online tablespace offline so that it is temporarily unavailable for general use. The rest of the database remains open and available for users to access data. Conversely, you can bring an offline tablespace online to make the schema objects within the tablespace available to database users. The database must be open to alter the availability of a tablespace.
QUESTION NO: 4
You create a table with the PERIOD FOR clause to enable the use of the Temporal Validity feature of Oracle Database 12c.
Examine the table definition:
Which three statements are true concerning the use of the Valid Time Temporal feature for the
EMPLOYEES table? (Choose three.)
A. The valid time columns are visible by default when the table is described.
B. The valid time columns are not populated by the Oracle Server automatically.
C. The same statement may filter on both transaction time and valid temporal time by using the AS
OF TIMESTAMP and PERIOD FOR clauses.
D. Setting the session valid time using DBMS_FLASHBACK_ARCHIVENABLE_AT_VALID_TIME sets the visibility for data manipulation language (DML), data definition language (DDL), and queries performed by the session.
E. The valid time columns employee_time_start and employee_time_end are automatically created.
Answer: C,D,E
Explanation
A: To implement Temporal Validity(TV), 12c offers the option to have two date columns in that table which is having TV enabled using the new clause Period For in the Create Table for the newly created tables or in the Alter Table for the existing ones. The columns that are used can be defined while creating the table itself and will be used in the Period For clause or you can skip having them in the table's definition in the case of which, the Period For clause would be creating them internally.
E: ENABLE_AT_VALID_TIME Procedure
This procedure enables session level valid time flashback.
QUESTION NO: 5
