User SCOTT executes the following command on the EMP table but has not issued COMMIT, ROLLBACK, or any data definition language (DDL) command:
SQL> SELECT ename FROM emp
WHERE job='CLERK' FOR UPDATE OF empno;
SCOTT has opened another session to work with the database instance. Which three operations would wait when issued in SCOTT's second session? (Choose three.)
LOCK TABLEemp IN SHARE MODE;
LOCK TABLEemp IN EXCLUSIVE MODE;
UPDATEemp SET sal=sal*1.2 WHERE job=ANAGER?UPDATE emp SET sal=sal*1.2 WHERE job=?ANAGER?
INSERT INTOemp(empno,ename) VALUES (1289,'Harry');
SELECTename FROM emp WHERE job='CLERK' FOR UPDATE OF empno;
Which three statements are true about logical structures of the Oracle database? (Choose three.)
Each segment contains one or more extents.
Multipletablespaces can share a single data file.
A data block is the smallest unit of input/output (I/O) in data files.
It is possible to havetablespaces of different block sizes in a database.
Each data block in the database always corresponds to one operating system block.
You are managing an Oracle Database 11g database. You configured the database to run in ARCHIVELOG mode. Which two statements are true in this scenario? (Choose two.)
You must shut down the database instance to perform the backups.
You must configure the Flash Recovery Area (FRA) for the database.
You can perform complete database backups without closing the database.
All the previous closed database backups including control files become invalidafteryou configure the database to ARCHIVELOG mode.
Which two statements are true regarding listeners? (Choose two.)
Listeners use only the TCP/IP protocol.
Multiple listener processes can run simultaneously on a host.
Multiple database instances can be registered with a single listener.
The listener-related errors can be traced only at the administrative level.
Only one database instance can be registered with a single listener at any time.
View the Exhibit to examine the output of the DBA_OUTSTANDING_ALERTS view. After 30 minutes, you executed the following command:
SQL> SELECT reason,metric_value FROM dba_outstanding_alerts;
Tablespace [TEST] is [28 perce 28.125 nt] full
What could be the reason for the elimination of the other rows in the output?
An Automatic Workload Repository snapshot has been taken recently.
The non-threshold-based alerts are transferred to DBA_ALERT_HISTORY.
The threshold alerts conditions are cleared and the alerts are transferred to BA_ALERT_HISTORY.
The threshold alerts related to database metrics are permanently stored in DBA_ALERT_HISTORY but not the threshold alerts related to instance metrics.
You have two database servers SEMP and SACCT. The database in the SEMP server maintains the employee information and the database in the SACCT server maintains the accounts payable information. The employees submit the expense reports to the accounts payable department. A user of the accounts payable database wants to extract the employee information from the database in the SEMP server for cross-verification. Which schema object enables the user to access the information from the remote database?
In a new installation of Oracle Database 11g, you perform these activities:
Organize software and data on different subdirectories to avoid poor performance.
Use consistent naming conventions for database files.
Separate administrative information pertaining to the database in different directories.
Which option corresponds to the type of activities you performed?
Oracle Managed Files
Oracle Grid Architecture
Optimal Flexible Architecture
Oracle database architecture
Automatic Storage Management
You configured the Flash Recovery Area (FRA) for your database. The database instance is running in ARCHIVELOG mode. The default location for the archived
redo log files is the Flash Recovery Area. Which two files are removed automatically if the space is required in the FRA as per the retention policy? (Choose two.)
Flashback log files
Backups that have become obsolete
User managed backups of the data files and control files
Archived redo log files that have multiple copies in a different archive location and not backed up
All the database users are presently connected to the database instance and working. The HR user has opened three database sessions and executed the following command in one of his sessions:
SQL> UPDATE persons SET ccode='U031' WHERE ccode='U029'; 123 rows updated.
SQL> DELETE FROM persons WHERE exp='Y';
The SYS user opens a new session after HR executed the above commands. Which sessions can see the effect of the UPDATE and DELETE commands?
All sessions of the HR user only
All sessions of the HR user and the SYS user
The session of the HR user that executed the commands
All the sessions for which the database users have access privilege to the PERSONS table
View the Exhibit and examine the attributes of an undo tablespace. In an OLTP system, the user SCOTT has started a query on a large table in the peak transactional hour that performs bulk inserts. The query runs for more than 15 minutes and then SCOTT receives the following error:
ORA-01555: snapshot too old
What could be the reason for this error?
The query is unable to get a read-consistent image.
There is not enough space in Flash Recovery Area.
There is not enough free space in the flashback archive.
The query is unable to place data blocks in undotablespace.
The user HR receives the following error while inserting data into the TTK table: ERROR at line 1: ORA-01653: unable to extend table HR.TTK by 128 in tablespace SMD Upon investigation, you find that SMD is a small file tablespace.Which three action would allow the user to insert data? (Choose three.)
Add a data file to the SMDtablespace.
Add a data file to the temporarytablespace associated with the user HR.
Resize the data file associated with the SMDtablespace to make it larger.
Alter the data file associated with the SMDtablespace to grow automatically.
Change the segment space management for the SMDtablespace to automatic.
Which two statements are true about checkpointing? (Choose two.)
The checkpoint frequency decreases with the smaller redo log file size.
It ensures that all committed data is written to the data files during normal shutdown.
The frequent full checkpoint in a database can cause the overall degradation of the database performance.
It prompts the Checkpoint (CKPT) process to write data to the data files and redo information to the online redo log files.
Which two statements are true regarding the Oracle Data Pump export and import operations? (Choose two.)
You cannot export data from a remote database.
You can rename tables during an import operation.
You can overwrite existing dump files during an export operation.
You can compress the data during export but not the metadata because it is not supported.
View the Exhibit. You are creating an additional database by using the Database Configuration Assistant (DBCA). You opted to create a General Purpose database and during the database creation realize that the Block Size field is not enabled. What could be the reason for this?
You have chosen the File System option as the storage option.
You have chosen the Automatic Storage Management (ASM) as the storage option.
The data block size can be increased only when DBCA is invoked from Oracle Universal Installer (OUI).
You are using General Purpose template and not the Custom Database template to create the database.
Your database is functional with a peak load for the last one hour. You want to preserve the performance statistics collected during this period to be used for comparison when you analyze the performance of the database in the future. What action would you take to achieve this task?
Insert finding directives for ADDM tasks in the future.
Create a baseline on a pair of snapshots spanning the peak-load period.
Decrease the snapshot interval in the AWR to collect more snapshots during thepeakload period.
Set the snapshot retention period in the Automatic Workload Repository (AWR) to zero to avoid automatic purging of snapshots.
You have statistics collected for some selected tables. Your requirement is that the statistics for the tables and all dependent indexes must not be overwritten by further statistics collection until a certain point of time. How would you achieve this?
Lock statistics for the tables.
Change STALE_PERCENT to zero for the tables.
Set the TIMED_STATISTICS parameter to TRUE.
Set the STATISTICS_LEVEL parameter to BASIC.
Set the OPTIMIZER_USE_PENDING parameter statistics to TRUE.
Which two kinds of failures make the Data Recovery Advisor (DRA) generate a manual checklist? (Choose two.)
Failure when no standby database is configured
Failure because a data file is renamed accidentally
Failure that requires no archive logs to be applied for recovery
Failure due to loss of connectivity-for example, an unplugged disk cable

Sat and passed the exam after months of study and several 'lab installs' I did find it strange the whole test is pretty much based off of maintaining voice networks rather than installing them. Now when I can be assed to finish my CCNP Route is a different story.
