NO.1 Exadata Database Machine offers an Intelligent Platform Management Interface for the
various components in the Exadata product. Which option is true?
A. IPMI can be used to remotely start and stop servers.
B. IPMI can be used to remotely log in to the operating system.
C. IPMI commands can be executed by using SNMP traps.
D. IPMI settings can be secured by backing up the Oracle Linux installation on the storage system.
Answer: A

Oracle   1z0-485 examen   certification 1z0-485   1z0-485   1z0-485 examen   certification 1z0-485
Explanation:
IPMI - short for Intelligent Platform Management Interface - is an interface standard that allows
remote management of a server from another using standardized interface. The servers in the
Exadata Database Machine follow that. It's not an Exadata command but rather a general Linux one.
To power on a cell or database server, issue this from another server: # ipmitool -H prolcel01-ilom
-U root chassis power on
To stop a server, use the shutdown command. To stop immediately and keep it down, i.e. not reboot,
execute:# shutdown -h -y now

NO.2 A customer has three databases named CC. FIN, and DW. The CC database is for their
CallCenter. Even a slight decrease in the response time of the database would mean more people
"on hold" in their data center. The orders received through the CallCenter are stored in the Finance
(FIN) database. Both databases, CC and FIN, serve as sources for the Data Warehouse (DW)
database. All databases use the same Automatic Storage Management (ASM) diskgroup and
therefore, the same physical disks on Exadata storage. The customer wants to dynamically control
the resources that are available for the CallCenter database because this has direct impact on their
operations?
Which option should be implemented?
A. DBRMon the CC database
B. DBRM on all the databases
C. IORM, because DBRM cannot be changed for an existing session
D. IORM and DBRM

NO.3 Consider this CellCLI command:
CellCLI> CREATE GRIDDISK ALL HARDDISK PREFIX=data, size=423G;
Which two statements describe what happens when you execute this command?
A. It creates one 423 GB grid disk on the first available cell hard disk.
B. It creates one 423 GB grid disk on each available cell hard disk.
C. It creates grid disks on the outermost 423 GB that is available on each hard disk.
D. It creates grid disks on the innermost 423 GB that is available on each hard disk.
E. It creates an Exadata Smart Flash Cache on all flash drives.
Answer: B,C

certification Oracle   1z0-485 examen   1z0-485 examen   certification 1z0-485   1z0-485
Explanation:
* Example: CellCLI> create griddisk all harddisk prefix=temp_dg, size=570G This command will
create 12 Griddisks, each of 570G in size from the outer (fastest) sectors of the underlying Harddisks.
It fills up the first 2 Celldisks entirely, because they have just 570G space free - the rest is already
consumed by the OS partition.

NO.4 Changes for Linux system performance optimization
Which of the software changes listed are permitted on Exadata Storage Servers?
A. 1, 2, 3, and 4
B. only 3 '
C. none
D. only 2
E. only 1 and 2
F. only 2 and 3
Answer: E

certification Oracle   certification 1z0-485   certification 1z0-485   1z0-485 examen
Explanation:
1. The Storage Server Patch is responsible for keeping our cell nodes always up-todate, fixing
possible problems, and this patch includes different component patches, like kernel patches,
firmware, operation system, etc... for the Storage Server. Incorrect: 3,4: security scan tools changes
and Linux system performance optimization changes would be on the database server.
4. The mpstat output from OS Watcher shows a database node as being 90% idle on an average.
What would you do to get a full picture of CPU utilization on the entire Exadata RAC cluster?
A. Average the mpstat id1 output from all the nodes.
B. Ask application users if they have noticed a slowdown in screen response.
C. Look for an increase in batch job servicing times.
D. A & B above
Answer: A

NO.5 Identify three best practices for applying asmdeactivationoutcome es on Exadata Database
Servers and Exadata Storage Servers?
A. Backing up database servers and storage cells is not recommended before performing planned
maintenance.
B. Database server updates can be rolled back using the the "yum downgrade" procedure.
C. Bundle patches do not require testing before being installed on a production system.
D. It is recommended that Exadata systems with Data Guard configured use the "Standby First"
patching approach.
E. Patching should never be interrupted due to a connection drop. It is therefore recommended that
you use VNC or the screen utility.
F. Before patching cells in a rolling manner, you must check asmdeactivationoutcome amModestatus
and make sure that cells on all disks are online and that disks can be deactivated.
Answer: D,E,F

3.Changes for security scan tools

NO.7 Which two statements are true about enabling write-back flash cache?
A. When enabling write-back flash cache in a non rolling manner, it is important to ensure that
asmdeactivatonoutcome is set to YES and asmModestatus is set to ONLINE for all grid disks.
B. Before using write-back flash cache, you need to verify the minimum required versions.
C. Before write back-flash cache is enabled, you need to drop the Flash Cache first.
D. The setting flashCacheMode should be set to writeback by updating cellinit.ora and restarting
cellsrv.
E. When enabling write-back flash cache in a rolling manner, dcli should be used to inactivate the
grid disks on all cells first.
Answer: B,C

Oracle examen   certification 1z0-485   certification 1z0-485   1z0-485 examen
Explanation:
B: Exadata storage version 11.2.3.2.1 is the minimum version required to use this write back flash
cache option.
C: Steps for Enabling Write back flash cache:
First of all, you don't need the stop CRS or database (This is ROLLING method) ,you can do it cell
by cell.
*drop flashcache
*Be sure asmdeactivationoutcome is YES is before disabling grid disk

NO.8 You get a Host Unreachable error when you attempt to connect to a server through a network
terminal command line. What are two other ways in which you can connect?
A. Use the ILOM Web GUI.
B. Use the dcli command at the root prompt on a database node.
C. Attach a terminal device to the back panel of the server with a serial cable.
D. Connect by using SQL *Plus.
E. Log in as root on the database node using the Net1 IP address.
Answer: A,C

certification Oracle   1z0-485 examen   certification 1z0-485   1z0-485 examen
Explanation:
In addition to gaining shell access via SSH to manage your Exadata servers, you can also access them
from the Integrated Lights Out Management (ILOM) console or KVM console.
and should typically not require modifications unless you have changed network information inside
your database machine.
Note: A KVM switch (with KVM being an abbreviation for "keyboard, video and mouse") is a
hardware device that allows a user to control multiple computers from one or more[1] keyboard,
video monitor and mouse. Although multiple computers areconnected to the KVM, typically a
smaller number of computers can be controlled at any given time

NO.1 In your database, you want to ensure that idle sessions that are blocking active are
automatically terminated after a specified period of time.
How would you accomplish this?
A. Setting a metric threshold
B. Implementing Database Resource Manager
C. Enabling resumable timeout for user sessions
D. Decreasing the value of the IDLE_TIME resource limit in the default profile
Answer: D

certification Oracle   1Z0-060 examen   certification 1Z0-060
Explanation:
An Oracle session is sniped when you set the idle_time parameter to disconnect inactive sessions.
(It's only like sniping on ebay in that a time is set for an action to occur.)
Oracle has several ways to disconnect inactive or idle sessions, both from within SQL*Plus via
resources profiles (connect_time, idle_time), and with the SQL*net expire time parameter. Here are
two ways to disconnect an idle session:
Set the idle_time parameter in the user profile Set the sqlnet.ora parameter expire_time

NO.2 Your multitenant container database (CDB) contains a pluggable database, HR_PDB. The
default permanent tablespace in HR_PDB is USERDATA. The container database (CDB) is open and
you connect RMAN.
You want to issue the following RMAN command:
RMAN > BACKUP TABLESPACE hr_pdb:userdata; Which task should you perform before issuing the
command?
A. Place the root container in ARHCHIVELOG mode.
B. Take the user data tablespace offline.
C. Place the root container in the nomount stage.
D. Ensure that HR_PDB is open.
Answer: A

certification Oracle   1Z0-060   1Z0-060 examen   certification 1Z0-060   1Z0-060   1Z0-060 examen

NO.3 You database is running an ARCHIVELOG mode.
The following parameter are set in your database instance:
LOG_ARCHIVE_FORMAT = arch+%t_%r.arc
LOG_ARCHIVE_DEST_1 = 'LOCATION = /disk1 /archive'
DB_RECOVERY_FILE_DEST_SIZE = 50G
DB_RECOVERY_FILE = '/u01 /oradata'
Which statement is true about the archived redo log files?
A. They are created only in the location specified by the LOG_ARCHIVE_DEST_1 parameter.
B. They are created only in the Fast Recovery Area.
C. They are created in the location specified by the LOG_ARCHIVE_DEST_1 parameter and in the
default location $ORACLE_HOME/dbs/arch.
D. They are created in the location specified by the LOG_ARCHIVE_DEST_1 parameter and the
location specified by the DB_RECOVERY_FILE_DEST parameter.
Answer: A

Oracle   1Z0-060   1Z0-060 examen   certification 1Z0-060
Explanation:
You can choose to archive redo logs to a single destination or to multiple destinations. Destinations
can be local-within the local file system or an Oracle Automatic Storage Management (Oracle ASM)
disk group-or remote (on a standby database). When you archive to multiple destinations, a copy of
each filled redo log file is written to each destination. These redundant copies help ensure that
archived logs are always available in the event of a failure at one of the destinations. To archive to
only a single destination, specify that destination using the LOG_ARCHIVE_DEST and
LOG_ARCHIVE_DUPLEX_DEST initialization parameters. ARCHIVE_DEST initialization parameter. To
archive to multiple destinations, you can choose to archive to two or more locations using the
LOG_ARCHIVE_DEST_n initialization parameters, or to archive only to a primary and secondary
destination using the LOG_ ARCHIVE_DEST and LOG_ARCHIVE_DUPLEX_DEST initialization
parameters.

NO.4 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.
A. Missing or stale histogram statistics
B. Undersized shared pool
C. High clustering factor for the indexes
D. High value for the DB_FILE_MULTIBLOCK_READ_COUNT parameter
E. Oversized buffer cache
Answer: A,C,D

certification Oracle   1Z0-060 examen   1Z0-060   certification 1Z0-060   certification 1Z0-060   1Z0-060 examen
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.

NO.5 The trace files be aggregated by using the tkprof utility.
Identify the correct outcome and the step to aggregate by using tkprof utility?
A. 1
B. 2 and 4
C. 2 and 5
D. 3 and 4
E. 3 and 5
Answer: B

Oracle   certification 1Z0-060   certification 1Z0-060
Explanation:
Tracing information is present in multiple trace files and you must use the trcsess
tool to collect it into a single file.
Incorrect:
Not 1: Parameter service_name
Name of the service for which tracing is enabled.
module_name
Name of the MODULE. An optional additional qualifier for the service.
Note:
*The procedure enables a trace for a given combination of Service, MODULE and ACTION name. The
specification is strictly hierarchical: Service Name or Service Name/MODULE, or Service Name,
MODULE, and ACTION name must be specified. Omitting a qualifier behaves like a wildcard, so that
not specifying an ACTION means all ACTIONs. Using the ALL_ACTIONS constant achieves the same
purpose.
*SERV_MOD_ACT_TRACE_ENABLE Procedure
This procedure will enable SQL tracing for a given combination of Service Name, MODULE and
ACTION globally unless an instance_name is specified.
*DBMS_MONITOR.SERV_MOD_ACT_TRACE_ENABLE(
service_name IN VARCHAR2,
module_name IN VARCHAR2 DEFAULT ANY_MODULE,
action_name IN VARCHAR2 DEFAULT ANY_ACTION,
waits IN BOOLEAN DEFAULT TRUE,
binds IN BOOLEAN DEFAULT FALSE,
instance_name IN VARCHAR2 DEFAULT NULL);
4. In a recent Automatic Workload Repository (AWR) report for your database, you notice a high
number of buffer busy waits. The database consists of locally managed tablespaces with free list
managed segments.
On further investigation, you find that buffer busy waits is caused by contention on data blocks.
Which option would you consider first to decrease the wait event immediately?
A. Decreasing PCTUSED
B. Decreasing PCTFREE
C. Increasing the number of DBWN process
D. Using Automatic Segment Space Management (ASSM)
E. Increasing db_buffer_cache based on the V$DB_CACHE_ADVICE recommendation
Answer: D

Oracle examen   1Z0-060   1Z0-060   1Z0-060   1Z0-060 examen   1Z0-060 examen
Explanation:
* Automatic segment space management (ASSM) is a simpler and more efficient way of managing
space within a segment. It completely eliminates any need to specify and tune the pctused,freelists,
and freelist groups storage parameters for schema objects created in the tablespace. If any of these
attributes are specified, they are ignored.
*Oracle introduced Automatic Segment Storage Management (ASSM) as a replacement for
traditional freelists management which used one-way linked-lists to manage free blocks with tables
and indexes. ASSM is commonly called "bitmap freelists" because that is how Oracle implement the
internal data structures for free block management.
Note:
*Buffer busy waits are most commonly associated with segment header contention onside the data
buffer pool (db_cache_size, etc.).
*The most common remedies for high buffer busy waits include database writer (DBWR) contention
tuning, adding freelists (or ASSM), and adding missing indexes.
5. You executed this command to create a password file:
$ orapwd file = orapworcl entries = 10 ignorecase = N
Which two statements are true about the password file?
A. It will permit the use of uppercase passwords for database users who have been granted the
SYSOPER role.
B. It contains username and passwords of database users who are members of the OSOPER
operating system group.
C. It contains usernames and passwords of database users who are members of the OSDBA
operating system group.
D. It will permit the use of lowercase passwords for database users who have granted the SYSDBA
role.
E. It will not permit the use of mixed case passwords for the database users who have been granted
the SYSDBA role.
Answer: A,D

certification Oracle   certification 1Z0-060   1Z0-060
Explanation:
* You can create a password file using the password file creation utility, ORAPWD.
* Adding Users to a Password File
When you grant SYSDBA or SYSOPER privileges to a user, that user's name and privilege information
are added to the password file. If the server does not have an EXCLUSIVE password file (that is, if the
initialization parameter REMOTE_LOGIN_PASSWORDFILE is NONE or SHARED, or the password file is
missing), Oracle Database issues an error if you attempt to grant these privileges.
A user's name remains in the password file only as long as that user has at least one of these two
privileges. If you revoke both of these privileges, Oracle Database removes the user from the
password file.
*The syntax of the ORAPWD command is as follows:
ORAPWD FILE=filename [ENTRIES=numusers] [FORCE={Y|N}] [IGNORECASE={Y|N}]
[NOSYSDBA={Y|N}]
*IGNORECASE If this argument is set to y, passwords are case-insensitive. That is, case is ignored
when comparing the password that the user supplies during login with the password in the
password file.

NO.6 The trace files may be aggregated by using the trcess utility.

NO.7 Your database has the SRV1 service configured for an application that runs on middle-tier
application server. The application has multiple modules. You enable tracing at the service level by
executing the following command:
SQL > exec DBMS_MONITOR.SERV_MOD_ACT_TRACE_ENABLE ('SRV1');
The possible outcome and actions to aggregate the trace files are as follows:
1.The command fails because a module name is not specified.
2.A trace file is created for each session that is running the SRV1 service.
3.An aggregated trace file is created for all the sessions that are running the SRV1 service.

NO.8 Identify two situations in which the alert log file is updated.
A. Running a query on a table returns ORA-600: Internal Error.
B. Inserting a value into a table returns ORA-01722: invalid number.
C. Creating a table returns ORA-00955: name us already in used by an existing objects.
D. Inserting a value into a table returns ORA-00001: unique constraint (SYS.OK_TECHP) violated.
E. Rebuilding an index using ALTER INDEX . . . REBUILD fails with an ORA-01578: ORACLE data block
corrupted (file # 14, block # 50) error.
Answer: A,E

Oracle   1Z0-060   1Z0-060   1Z0-060   certification 1Z0-060
Explanation:
The alert log is a chronological log of messages and errors, and includes the following items:
*All internal errors (ORA-600), block corruption errors (ORA-1578), and deadlock errors (ORA-60)
that occur
*Administrative operations, such as CREATE, ALTER, and DROP statements and STARTUP ,
SHUTDOWN, and ARCHIVELOG statements
*Messages and errors relating to the functions of shared server and dispatcher processes
*Errors occurring during the automatic refresh of a materialized view
*The values of all initialization parameters that had nondefault values at the time the database and
instance start
Note:
*The alert log file (also referred to as the ALERT.LOG) is a chronological log of messages and errors
written out by an Oracle Database. Typical messages found in this file is: database startup,
shutdown, log switches, space errors, etc. This file should constantly be monitored to detect
unexpected messages and corruptions.
