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 examen   1z1-485 examen   1z1-485
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 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   1z1-485   1z1-485 examen   1z1-485 examen   certification 1z1-485
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.

ID. 835032.1)
* - This is for the first generation (V1) for Oracle Exadata, using HP hardware.

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.
Answer: D,E,F

NO.5 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.6 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

certification Oracle   1z1-485 examen   1z1-485 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.7 Consider the following software changes that are performed manually on a Linux server:
1.Changes for Linux kernel firewall configuration
2.Changes for custom performance monitoring tools
3.Changes for security scan tools

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   1z1-485 examen   1z1-485
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 When more than one policy is attached to a policy subject, the combination of policies needs
to be valid. Which statement is true about the valid combination of policies for a policy subject?
A. Only one MTOM policy can be attached to a policy subject.
B. More than one Reliable Messaging policy can be attached to a policy subject.
C. Both a Reliable Messaging policy and a WS-Addressing policy cannot be attached to the same
policy subject.
D. Only one security policy can be attached to a policy subject.
Answer: A

Oracle   1Z0-478 examen   1Z0-478
Explanation:
Note:
*Within a SOA composite application, you must attach the Oracle WS-MTOM policy to service and
reference binding components to receive and send MTOM (MIME binary) attachments within
Oracle SOA Suite.
*Message Transmission Optimization Mechanism (MTOM)
Ensures that attachments are in MTOM format. This format enables binary data to be sent to and
from web services. This reduces the transmission size on the wire.
*ReliabilityPolicy
Supports the WS-Reliable Messaging protocol. This guarantees the end-to-end delivery of
messages.
* Addressing Policy Verifies that simple object access protocol (SOAP) messages include
WS-Addressing headers in conformance with the WS-Addressing specification. Transport-level data
is included in the XML message rather than relying on the network-level transport to convey this
information.

NO.2 Which two approaches are valid when using dynamic partner links in a BPEL process?
A. A WSDL file, which contains multiple services that use the same portType, is available at design
time, but the decision to determine which service is used can only be made at runtime.
B. When the BPEL process is designed, the endpoint URL of the WSDL file is known but the services
and port types are not known.
C. When the BPEL process is designed, the services and port types of the WSDL file are known but
the endpoint URI is not known.
D. A WSDL file, which contains multiple services that use different portTypes, is available at design
time, but the decision to determine which server us used can only be made at runtime.
Answer: A,C

Oracle examen   certification 1Z0-478   1Z0-478 examen   certification 1Z0-478   1Z0-478
Explanation:
A (not D):How To Create a Dynamic Partner Link at Design Time for Use at Runtime
To create a dynamic partner link at design time for use at runtime:
etc
C (not B):The BPEL specification mandates that only the partner endpoint reference (EPR) can be
changed dynamically. In BPEL terms, only the partnerRole of a partner link element can have a new
value assigned. The myRole value doesn't change after the BPEL has been deployed.
Note: *Dynamic Partner Links and Dynamic Addressing During the design-time of an application,
you may need to configure certain services whose endpoints (addresses) are not known beforehand,
or it may be necessary to change an endpoint reference while the application is running. The
Dynamic Partner link feature allows you to dynamically assign an endpoint reference to the partner
link. This means that you can use onepartner link for subsequent calls to different web-services
(provided that the services use the same interface). *For successful deployment of the process, a
partner link should be completely defined. When you deploy the project, the WSDL file for the
partner link should contain and define both the abstract and the concrete information for the
partner link, including address and port, though later the concrete information can be changed
independently from the WSDL file.

NO.3 A partner needs to access services that are defined in one of your Service Composite
Architecture (SCA) applications via a web service interface. Which approach (and accompanying
reasoning) describes a loosely coupled and robust solution?
A. Use Oracle Service Bus to provide an Interface layer over your SCA application. This enables you
to hide the locations of your SCA application, perform load-balancing across those endpoints, and
provide the ability to define service level agreements to help ensure that you are meeting your
contractual obligations to the partner.
B. Use the Mediator component to provide a web service interface to your SCA application. This
arrives you the flexibility of using the industry standard XSLT technology to perform translation and
transformations.
C. Use Oracle Service Bus to provide an interface layer over your SCA application. This enables you
to "skin" your SCA application with a web service interface and still provide a robust experience to
the partner.
D. Allow the partner simply to connect directly to the SCA application. This provides the best
performance and helps keep the partner happy.

NO.4 Which two features are provided by decision tables?
A. Sets of input data can be bucketed and reviewed for gaps.
B. Data sets can be reviewed for conflicts.
C. Data can be used for only one rule evaluation.
D. A rule evaluation can be used only to enter new output data.
Answer: A,B

Oracle examen   certification 1Z0-478   certification 1Z0-478   certification 1Z0-478
Explanation:
After you create a Decision Table there are operations that you may want to perform on the
Decision Table, including the following:
(A)Find and fix gaps in a Decision Table (B)Finding and resolving conflicts between rules in a
Decision Table Compact or split cells in a Decision Table Merge a condition or split a condition in a
Decision Table
A: *Compact the Decision Table
In this step you compact the rules to merge from eighteen rules to nine rules. This automatically
eliminates the rules that are not needed and preserves the no gap, no conflict properties for the
Decision Table.
*The Conditions area in a Decision Table includes one or more condition rows. Each condition row
has a condition expression and, for each rule, a condition cell. A condition expression is an
expression that you build in Rules Designer. The condition expression is often a fact property or a
function result, but it can be any expression that has a type that can be associated with a bucketset.
B:A Decision Table displays multiple related rules in a single spreadsheet-style view. In Rules
Designer a Decision Table presents a collection of related business rules with condition rows, rules,
and actions presented in a tabular form that is easy to understand. Business users can compare cells
and their values at a glance and can use Decision Table rule analysis features by clicking icons and
selecting values in Rules Designer to help identify and correct conflicting or missing cases.

NO.5 In your solution, a web service client needs to invoke a series of three web services in support
of a single transaction. The third web service needs the identity of the original web service client.
Which statement describes how the identity is made available by Oracle Web Services Manager
(OWSM)?
A. The transaction manager accesses an internal table that maintains credentials used to invoke
each individual web service in the chain.
B. Each web service in the chain does its own authentication so the third web service handles its
own identity checking.
C. OWSM sets the user in the Java Authentication and Authorization (JAAS) Subject when the first
web service successfully authenticates, and the Java Subject is used by subsequent web services to
access the identity.
D. OWSM stores a SAML token from the first web service invocation in a database table, and that
table is accessed by subsequent web services in the chain to retrieve identity.
Answer: D

certification Oracle   1Z0-478 examen   certification 1Z0-478   certification 1Z0-478
Explanation:
Oracle Web Services Manager is a component of the Oracle Enterprise Manager Fusion Middleware
Control, a run-time framework that provides centralized management and governance of Oracle
SOA Suite environments and applications. You create and configureOracle Web Services Manager
policies in Oracle Enterprise Manager, and those policies are persisted in a policy store (a database
is recommended). Oracle Web Services Manager lets you define policies against an LDAP directory
and generate standard security tokens (such as SAML tokens) to propagate identities across multiple
Web services used in a single transaction.

NO.6 Identify two correct descriptions of Oracle Web Services Manager (OWSM).
A. It enables you to externalize web services security from the applications youbuild.
B. It manages policies in a distributed policy manager that serves as a single policy enforcement
point.
C. Use security and management events, captured by OWSM agents, are displayed using Oracle
BAM.
D. It supplies predefined security policies that enable declarative security and management
definition.
E. It uses Oracle Event Processing (OEP) to determine when security violations have occurred.
Answer: B,C

Oracle examen   certification 1Z0-478   1Z0-478 examen   certification 1Z0-478   1Z0-478 examen   certification 1Z0-478
Explanation:
Note: *Oracle WSM allows companies to (1) centrally define and store declarative policies applied
to the multiple web services making up a SOA infrastructure, (2) locally enforce security and
management policies through configurable agents, and (3) monitor runtime security events such as
failed authentication or authorization.
*Oracle Web Services Manager offers a comprehensive and easy-to-use solution for policy
management and security of service infrastructure. It provides visibility and control of the policies
through a centralized administration interface offered by Oracle Enterprise Manager.

NO.7 Identify two features of Oracle BAM.
A. Enterprise Manager's monitoring capabilities are central to Oracle BAM's ability to monitor
performance indicators.
B. You can analyze and present Information from activities spanning multiple systems and
applications.
C. Rich browser-based dashboards provide visibility into current values of key performance
indicators (KPIs).
D. There is a built-in trouble ticket system to track assignment and completion of corrective actions.
Answer: A,C

Oracle examen   1Z0-478 examen   1Z0-478   1Z0-478 examen
Explanation:
Note: *Oracle Business Activity Monitoring (Oracle BAM) gives business executives the ability to
monitor their business services and processes in the enterprise, to correlate KPIs down to the actual
business process themselves, and most important, to change business processes quickly or to take
corrective action if the business environment changes.

NO.8 You expand a business rule component that a colleague added to the BPEL process. You see an
Assign element named Facts_To_Rule_Service.
Which statement is true bout this Assign element?
A. It was added automatically based on entries that your colleague made in the dialog box that
approved when the business rule component was added to the BPEL model.
B. Your colleague manually added this Assign element after adding the business rule component to
the BPEL Model.
C. This Assign element was automatically added when your colleague manually addedthe
corresponding Rule_Service_To_Facts assign to the BPEL model.
D. You can delete this Assign because it was created for documentation purposes only.
Answer: A
