NO.9 Which three tasks can be automaticallyperformed by the Automatic Data Optimization feature of Information lifecycle Management (ILM)? (Choose three.)
A. Tracking the most recent read time for a tablesegment in a user tablespace
B. Tracking the most recent write time for atable segment in a user tablespace
C. Tracking insert time by row for table rows
D. Tracking the most recent write time for atable block
E. Tracking the most recent read time for a tablesegment in the SYSAUX tablespace
F. Tracking the most recent write time for atable segment in the SYSAUX tablespace
Answer: A,B,D Explanation: Incorrect:
Not E, Not F When Heat Map is enabled, all accesses are tracked by thein-memory activity tracking module. Objects in the SYSTEM and SYSAUXtablespaces are not tracked.
* To implement your ILM strategy, you can use Heat Map in OracleDatabase to track data access and modification.
Heat Map provides data access tracking at the segment-level and datamodification tracking at the segment and row level.
* To implement your ILM strategy, you can use Heat Map in OracleDatabase to track data access and modification. You can also use Automatic DataOptimization (ADO) to automate the compression and movement of data betweendifferent tiers of storage within the database.

NO.11 A user establishes a connection to a databaseinstance by using an Oracle Net. You want toensure that:
1 . The user account must be locked after fiveconsecutive unsuccessful login attempts. 2 . Data read per session must belimited for the user.
3 . The user cannot have more than threesimultaneous sessions.
4 . The user must have a maximum of 10 minutessession idle time before being logged off automatically.
Which two would you do to implement this?(Choose two.)
A. by alerting the appropriate user attributeswith an ALTER USER command
B. by using appropriate PASSWORD parameters setin the profile assigned to the user
C. by implementing Database Resource Manager andassign it a profile for the user
D. by implementing Database Resource Manager andassign it a role for the user
E. by using appropriate KERNEL parameters set inthe profile assigned to the user
Answer: B,E
NO.12 Identify three valid methods of opening,pluggable databases (PDBs).
A. ALTER PLUGGABLE DATABASE OPEN ALL ISSUED fromthe root
B. ALTER PLUGGABLE DATABASE OPEN ALL ISSUED froma PDB
C. ALTER PLUGGABLE DATABASE PDB OPEN issued fromthe seed
D. ALTER DATABASE PDB OPEN issued from the root
E. ALTER DATABASE OPEN issued from that PDB
F. ALTER PLUGGABLE DATABASE PDB OPEN issued fromanother PDB
G. ALTER PLUGGABLE DATABASE OPEN issued from thatPDB
Answer: A,E,G Explanation:
E: You can perform all ALTER PLUGGABLEDATABASE tasks by connecting to a PDB and running the corresponding ALTERDATABASE statement. This functionality is provided to maintain backwardcompatibility for applications that have been migrated to a CDB environment.
AG: When you issue an ALTER PLUGGABLE DATABASEOPEN statement, READ
WRITE is the default unless a PDB being opened belongs to a CDB thatis used as a physical standby database, in which case READ ONLY is the default.
You can specify which PDBs to modify in the following ways: List oneor more PDBs.
Specify ALL to modify all of the PDBs.
Specify ALL EXCEPT to modify all of the PDBs,except for the PDBs listed.

D. It writes the checkpoint position to thecontrol file.
Answer: C,D

NO.14 You are administering a database and youreceive a requirement to apply the following restrictions:
1 . A connection must be terminated after fourunsuccessful login attempts by user. 2 . A user should not be able to createmore than four simultaneous sessions.
3 . User session must be terminated after 15minutes of inactivity.
4 . Users must be prompted to change theirpasswords every 15 days. How would you accomplish these requirements?
A. by granting a secure application role to theusers
B. by creating and assigning a profile to theusers and setting the REMOTE_OS_AUTHENT parameter to FALSE
C. By creating and assigning a profile to theusers and setting the SEC_MAX_FAILED_LOGIN_ATTEMPTS parameter to 4
D. By Implementing Fine-Grained Auditing (FGA)and setting the REMOTE_LOGIN_PASSWORD_FILE parameter to NONE.
E. By implementing the database resource Managerplan and setting the SEC_MAX_FAILED_LOGIN_ATTEMPTS parameters to 4.
Answer: A
Explanation:
You can design your applications toautomatically grant a role to the user who is trying to log in, provided theuser meets criteria that you specify. To do so, you create a secure applicationrole, which is a role that is associated with a PL/SQL procedure (or PL/SQLpackage that contains multiple procedures). The procedure validates the user:if the user fails the validation, then the user cannot log in. If the userpasses the validation, then the procedure grants the user a role so that he orshe can use the application. The user has this role only as long as he or she islogged in to the application. When the user logs out, the role is revoked.
Incorrect:
Not B: REMOTE_OS_AUTHENT specifies whetherremote clients will be authenticated with the value of the OS_AUTHENT_PREFIXparameter.
Not C, not E: SEC_MAX_FAILED_LOGIN_ATTEMPTSspecifies the number of
authentication attempts that can be made by aclient on a connection to the server process.
After the specified number of failureattempts, the connection will be automatically dropped by the server process.
Not D: REMOTE_LOGIN_PASSWORDFILE specifieswhether Oracle checks for a password file.
Values: shared
One or more databases can use the passwordfile. The password file can contain SYS as well as non-
SYS users. exclusive
The password file can be used by only onedatabase. The password file can contain SYS as well as non-SYS users.
none
Oracle ignores any password file. Therefore,privileged users must be authenticated by the operating system.
Note:
The REMOTE_OS_AUTHENT parameter is deprecated.It is retained for backward compatibility only.
NO.15 The HR user owns the BONUSES table. HR grantsprivileges to the user TOM by using the command:
SQL> GRANT SELECT ON bonuses TO tom WITHGRANT OPTION; TOM then executes this command to grant privileges to the userJIM: SQL> GRANT SELET ON hr.bonuses TO jim;
Which statement is true?
A. TOM cannot revoke the SELECT ON HR.BONUSES privilege from JIM.
B. HR can revoke the SELECT ON HR.BONUSESprivilege from JIM.
C. JIM can grant the SELECT ON HR.BONUSESprivilege to other users, but cannot revoke the privilege from them.
D. HR can revoke the SELECT ON HR.BONUSESprivilege from TOM, which will automatically revoke the SELECT ON HR.BONUSESprivilege from JIM.
Answer: D
