NO.1 Which statement best describes the relationship between a SOA Service and service
Infrastructure?
A. Service infrastructure is a primary part of an SOA Service.
B. Service Infrastructure exposes the Service Interface and may satisfy some capabilities of the
Service Implementation.
C. Service infrastructure fulfills the Service Contract.
D. A SOA Service depends on the service infrastructure to satisfy some required capabilities.
E. A SOA Service uses the service infrastructure to generate the Service Interface.
Answer: B
Oracle certification 1z1-574 certification 1z1-574 1z1-574 examen 1z1-574
Explanation: The Service Infrastructure side typically provides the Service enablement
capabilities
for the implementation. These capabilities may include, exposing the interface as a
Web Service, handling SLA enforcement, security, data formatting, and others. Service
infrastructure should be utilized when possible, as it reduces the burden on Service
providers, from an implementation standpoint.

NO.2 Which three primary components form IT Strategies from Oracle (ITSO)?
A. Enterprise Technology Strategies
B. Maximum Availability Architecture

NO.4 Which statement best describes the relationship between a Service Contract and a Usage
Agreement as defined by the Oracle Reference Architecture (ORA)?
A. There is a one-to-one relationship between a Service Contract and a Usage Agreement. For
each Service Contract there is a corresponding Usage Agreement.
B. There may be multiple Usage Agreements associated with a single Service Contract.
C. There may be multiple Service Contracts associated with a single Usage Agreement.
D. There is a many-to-many relationship between Service Contracts and Usage Agreements.
E. There is no defined relationship between a Service Contract and a Usage Agreement.
Answer: B
certification Oracle 1z1-574 1z1-574 examen 1z1-574 1z1-574
Explanation: The Service Contract defines what the SOA Service agrees to provide to the
environment.
The service consumer Usage Agreement defines what a particular service consumer is
entitled to consume.
Each service might have several consumers.
The Service provider must ensure that the Service will satisfy the aggregate
specifications of all related usage agreements.
Note:
The usage agreement is not part of the Service; rather it defines what a particular service
consumer is entitled to consume from the Service.
Having both a usage agreement and a service contract provides a decoupling between
the service provider and service consumer. This not only facilitates reuse but also
provides a separation of concerns. The service contract defines the totality of what the
Service guarantees to provide, and can be written and validated independent of any
knowledge of specific service consumers. The usage agreement is service consumer
specific and defines what capabilities of the Service each consumer is allowed to
consume.

NO.5 Which of the following environments are typically clustered?
A. Development Environment
B. User Acceptance Testing (UAT) Environment
C. Staging Environment
D. Nonfunctional Testing Environment
Answer: B
Oracle 1z1-574 1z1-574 1z1-574 1z1-574
Explanation: UAT (also known as beta testing) : Formal testing with respect to user needs,
requirements, and business processes conducted to determine whether or not a system satisfies
the acceptance criteria and to enable the user, customers or other authorized entity to determine
whether or not to accept the system.
Incorrect answer:
The staging tier is a environment that is as identical to the production environment as possible.
The purpose of the Staging environment is to simulate as much of the Production environment as
possible. The Staging environment can also double as a Demonstration/Training environment.

the
Client Tier and the Service Tier as well as Message Security?
A. Oracle platform Security Services
B. Oracle WebCenter
C. Application Development Framework
D. Oracle HI IP Server
Answer: A
Oracle 1z1-574 1z1-574 examen 1z1-574 1z1-574
Explanation: Oracle Platform Security Services comprises Oracle WebLogic Server's internal
security framework and Oracle's security framework (referred to as Oracle Platform Security).
OPSS delivers security as a service within a comprehensive, standards-based security framework.
The Security Services includes SSL:Hypertext Transfer Protocol Secure (HTTPS) is a combination
of Hypertext Transfer Protocol (HTTP) with SSL/TLS protocol.
Note:Oracle Platform Security Services (OPSS) provides enterprise product development teams,
systems integrators (SIs), and independent software vendors (ISVs) with a standards-based,
portable, integrated, enterprise-grade security framework for Java Standard Edition (Java SE) and
Java Enterprise Edition (Java EE) applications.
OPSS provides an abstraction layer in the form of standards-based application programming
interfaces (APIs) that insulate developers from security and identity management implementation
details. With OPSS, developers don’t need to know the details of cryptographic key management
or interfaces with user repositories and other identity management infrastructures. Thanks to
OPSS, in-house developed applications, third-party applications, and integrated applications
benefit from the same, uniform security, identity management, and audit services across the
enterprise.
OPSS is the underlying security platform that provides security to Oracle Fusion Middleware
including products like WebLogic Server, SOA, WebCenter, ADF, OES to name a few. OPSS is
designed from the ground up to be portable to third-party application servers. As a result,
developers can use OPSS as the single security framework for both Oracle and third-party
environments, thus decreasing application development, administration, and maintenance costs.
