NO.1 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
Oracle受験記 1z0-485資格 1z0-485日記 1z0-485過去
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.2 Consider the following setup:
User A1 belongs to resource group High on Database A.
User B2 belongs to resource group Low on Database B.
User C3 is a user on Database C without any DBRM setup.
DBRM setup:
Database A: Resource group High gets 80% and Low gets 20%.
Database B: Resource group High gets 60% and Low gets 40%.
IORM setup:
Database A: Share=20, limit=5
Database B: Share=30, limit=10
Database C: 5 shares
Total number of shares in the IORM setup = 100
What percent of I/O will each database user theoretically be using when the Exadata storage unit
I/O throughout is used 100% and no other databases but A, B, and C are running?
A. Al = 36%, B2=18%, and C3=9%
B. Al = 33%, B2=33%, and C3=33%
C. AI = 10%, B2=5%, and C3=20%
D. Al = 8%, B2=12%, and C3=5%
E. Al = 5%, B2=10%, andC3=85%
Answer: E
Oracle問題 1z0-485虎の巻 1z0-485 1z0-485ふりーく
Explanation:
IORM setup limits Database A to 5%, and Database B is limited to 10%, while
Database C has not IORM limit.
Notethat the resource groups are for CPU allocation.
NO.3 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
Answer: A

NO.4 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.

NO.5 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講座 1z0-485ガイド 1z0-485フリーク
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.6 Which is the best location to point your customer to, for finding the latest Exadata patches?
A. owner's guide
B. Patch database in MyOracle Support
C. MyOracle Support note 888828.1
D. MyOracle Support for database patches, ULN for OS patches, and Sun Support for Server and
InfiniBand patches.
Answer: B
Oracle 1z0-485一発合格 1z0-485勉強法 1z0-485認定証
Explanation:
Before starting, we would like to share and note here two documents from My Oracle Support, aka
metalink. These notes must be the first place that you need to go to review before patching the
Exadata environment.
* (B) Database Machine and Exadata Storage Server 11g Release 2 (11.2) Supported Versions (Doc ID.
888828.1)
-This is for the second and third generation (V2 and X2) for Oracle Exadata, using Sun hardware.
* Database Machine and Exadata Storage Server 11g Release 1 (11.1) Supported Versions (Doc
ID. 835032.1)
* - This is for the first generation (V1) for Oracle Exadata, using HP hardware.
NO.7 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
Oracleガイド 1z0-485教科書 1z0-485難易度 1z0-485
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

NO.8 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 PDF 1z0-485合格率 1z0-485
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
