Q1. You are administering a multitenant container database (CDB) cdb1 that is running in 

archivelog mode and contains pluggable databases (PDBs), pdb_i and pdb_2. 

While opening pdb_1, you get an error: 

SQL> alter pluggable database pdb_1 open; 

ORA-011S7:cannotidentify/lockdatafile11-seeDBWRtracefile 

ORA-01110:data file 11:'/u01/app/oracle/oradata/cdb1/pcb_1/example01.dbf' 

To repair the failure, you open an RMAN session for the target database CDBSROOT. You 

execute the following as the first command: 

RMAN>REPAIRFAILURE; 

Which statement describes the consequence of the command? 

A. The command performs the recovery and closes the failure. 

B. The command produces an error because RMAN is not connected to the target database pdb_1. 

C. The command produces an error because the advise failure command was not executed before theREPAIRFAILUERcommand. 

D. The command executes successfully, performs recovery, and opens PDB_1. 

Answer:

Q2. Examine the command: 

SQL> RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL; 

In which two scenarios is this command required? 

A. The current online redo log file is missing. 

B. A data file belonging to a noncritical tablespace is missing. 

C. All the control files are missing. 

D. The database backup is older than the control file backup. 

E. All the data files are missing. 

Answer: A,B 

Q3. Your database instance is started using an SPFILE. You are connected to cdb$root, as a DBA. You issue: 

SQL> ALTER SYSTEM SET STATISTICS_LEVEL=ALL SCOPE=BOTH; 

Which two statements are true about the statistics level parameter? 

A. It is immediately set to all in the SPFILE and the CDB instance. 

B. It is immediately set to all in only those pluggable databases (PDBs) where the value is set to typical. 

C. It is immediately set to all only for cd3Sroot. 

D. It is immediately set to all in all PDBs where the statistics_level parameter is not set. 

E. It is set to all for all PDBs only in the SPFILE. 

Answer: A,B 

Q4. You have set the value of the NLS_TIMESTAMP_TZ_FORMATparameter 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: B,E 

Q5. In your database, there are tablespaces that were read-only when the last backup was taken. These tablespaces have not been made read/write since then. You want to perform an incomplete recovery on the database by using a backup control file. 

What precaution must you take for the read-only tablespaces before performing an incomplete recovery? 

A. All the read-only tablespaces should be taken offline. 

B. All the read-only tablespaces should be restored separately. 

C. All the read-only tablespaces should be renamed to have the MISSINGnnnn format. 

D. All the read-only tablespaces should be made online with logging disabled. 

Answer:

Q6. You want to consolidate databases for the CRM, ERP, and SCM applications by migrating them to pluggable databases (PDBs). 

You have already created a test system to support the consolidation of databases in a multitenant container database (CDB) that has multiple PDBs. 

What is the easiest way to perform capacity planning for consolidation? 

A. capturing the most resource-intensive SQL statements in a SQL Tuning Set on the production system and using the SQL Performance Analyzer on the test system 

B. capturing the workload on the production system and replaying the workload for one PDB at a time on the test system 

C. capturing the workload on the production system and using Consolidated Database Replay to replay the workload of all production systems simultaneously for all PDBs 

D. capturing the most resource-intensive SQL statements in a SQL Tuning Set on the production system and using the SQL Tuning Advisor on the test system 

Answer:

Q7. When is the UNDO_RETENTIONparameter value ignored by a transaction? 

A. when the data file of the undo tablespace is autoextensible 

B. when there are multiple undotablespaces available in a database 

C. when the undo tablespace is of a fixed size and retention guarantee is not enabled 

D. when Flashback Database is enabled 

Answer:

Reference:http://docs.oracle.com/cd/B19306_01/server.102/b14231/undo.htm(undo retention, see the bullets) 

Q8. You must unload data from the orders, order_items, and products database tables to four files using the External Tables. 

CREATE TABLE orders_ext (order_id, order_date, product_id, product_name,quantity) ORGANIZATION EXTERNAL ( TYPE ORACLE_DATAPUMP DEFAULT DIRECTORY ext.dir LOCATION (‘ordersl.dmp','orders2.dmp’,’orders3.dmp’,’lorders4.dmp') ) PARALLEL AS SELECT o.order_id,o.order_date,p.product_id,p.product_name,i.quantity FROM orders o,productsp,order_itemsi WHERE o.orderjd = i.order_id and i.product_id = p.product_id; 

You execute the command shown in the Exhibit, but only two files are created. Which parameter must be changed so that four files are created? 

A. TYPE 

B. LOCATION 

C. PARALLEL 

D. DEFAULT DIRECTORY 

E. ORGANIZATION EXTERNAL 

Answer:

Q9. Automatic Undo Management is enabled for your database. You want a user to retrieve metadata and historical data for a given transaction or for transactions in a given time interval. 

Which three are prerequisites to fulfill this requirement? 

A. Minimal supplemental logging must be enabled. 

B. The database must be running in archivelog mode. 

C. Flashback Data Archive must be created and the flashback archive administer system privilege must be granted to the user. 

D. The flashback any table privilege must be granted to the user. 

E. The select any transaction privilege must be granted to the user. 

F. Therecycle binparameter must be set to on. 

Answer: C,D,E 

Q10. You want the execution of large database operations to suspend, and then resume, in the event of space allocation failures. 

You set the value of the initialization parameter resumable_timeout to 3600. 

Which two statements are true? 

A. A resumable statement can be suspended and resumed only once during execution. 

B. Data Manipulation Language (DML) operations are resumable, provided that they are not embedded in a PL/SQL block. 

C. A suspended statement will report an error if no corrective action has taken place during a timeout period. 

D. Before a statement executes in resumable mode, the alter session enable resumable statement must be issued in its session. 

E. Suspending a statement automatically results in suspending a transaction and releasing all the resources held by the transaction. 

Answer: A,D
