  Web Services are a natural fit for building distributed computing platforms.

  *

  WSDL, SOAP, and XML promote language and platform independence and interoperability.

  *

  UDDI allows services deployed in a distributed infrastructure to be discovered and consumed.

  *

  Simple Object Access Protocol (SOAP) enables service binding and invocation using standards based protocols such as HTTP and JMS.

  *

  The platform for SOA should support the WS-* standards

  Note: Openness is the property of distributed systems such that each subsystem is continually open to interaction with other systems. Web services protocols are standards which enable distributed systems to be extended and scaled. In general, an open system that scales has an advantage over a perfectly closed and self-contained system.

• Question 102:

  Which one of the following types of access control should be used when access to a resource is dependent upon specific qualities of the user, for example, membership status, frequency of purchases, or level of certification?

  A. role-based access control
  B. rule-based access control
  C. discretionary access control
  D. content-dependent access control
  E. attribute-based access control
  C. discretionary access control

  ---

  Content dependent access control involves restricting access to content, such as documents and emails, based on embedded keywords or certain assigned metadata. It works by inspecting the content and applying rules to determine if access is permitted. This approach is taken by many Data Loss Prevention solutions. It is possible to combine content dependent access control with role-based access control in order to restrict access to content by established roles.

• Question 103:

  Which statement best describes how Service-Oriented Integration (SOI) differs from traditional Enterprise Application Integration (EAI)?

  A. SOI is Just like EAI except that a service bus is used Instead of a hub or message bus.
  B. SOI is different than hub-based EAI, but is the some as EAI using a message bus.
  C. SOI uses a point to-point integration approach based on the Web Services Industry standards.
  D. SOI uses SOA Services that are separate and distinct from the applications being integrated
  E. EAI integrates applications whereas SOA integrates SOA Services.
  E. EAI integrates applications whereas SOA integrates SOA Services.

  ---

  Enterprise Application Integration (EAI) is an approach for integrating multiple applications. EAI products are built around messaging products and are deployed in either a hub-and-spoke architecture or in a bus architecture. Some argue that service-oriented integration is actually a form EAI. This is not correct. EAI is an application-oriented architecture. EAI provides the mechanism to have applications interact to share data and functionality. Service-oriented integration adds the concept (and concrete deployment) of SOA Services that are separate and distinct, with a lifecycle that is independent, from any application in the computing environment.

• Question 104:

  Which of the following is the most correct definition of Grid computing?

  A. Grid computing refers to the ability to run computers off a power grid.
  B. Grid computing refers to the aggregation of multiple, distributed computing resources, making them function as a single computing resource with respect to a particular computational task.
  C. Grid computing refers to the vertical scaling of resources to add more capacity to the Infrastructure.
  D. Grid computing allows computing resources to be operated and managed independently, creating a distributed architecture.
  D. Grid computing allows computing resources to be operated and managed independently, creating a distributed architecture.

  ---

  Grid computing is a technology architecture that virtualizes and pools IT resources, such as compute power, storage, and network capacity into a set of shared services that can be distributed and re- distributed as needed. Grid computing involves server virtualization, clustering, and dynamic provisioning.

  Note: With Grid computing, groups of independent, modular hardware and software components can be pooled and provisioned on demand to meet the changing needs of businesses. Grid computing is really a form of distributed computing and it aims to deliver flexible and dynamic infrastructures using tiered optimization. It uses virtualization at various levels of the middleware and database layer to achieve it.

• Question 105:

  Which of the following statements are true about perimeter security?

  A. Though it is often associated with network security, it also applies to physical security measures as fences and locked doors.
  B. It is most effective when there is only one perimeter. For example, when inner perimetersare established, they reduce the effectiveness of outer perimeters.
  C. The Demilitarized Zone (DMZ) is the most protected zone of the network, which should be reserved for only the most sensitive data.
  D. Connections should not be permitted to span more than one perimeter or firewall.
  E. Perimeter security can be a component of a defense-in-depth strategy.
  F. Perimeter security is most effective for protection against insider threats.
  A. Though it is often associated with network security, it also applies to physical security measures as fences and locked doors.
  D. Connections should not be permitted to span more than one perimeter or firewall.
  E. Perimeter security can be a component of a defense-in-depth strategy.

  ---

  A: Your inner perimeter consists of the doors, windows and walls of your building(s). Protecting your inner perimeter is usually accomplished with locks, keys and alarm systems.

  D:

  E: Defense in depth is a security strategy in which multiple, independent, and mutually reinforcing security controls are leveraged to secure an IT environment. Defense in depth should be applied so that a combination of firewalls, intrusion detection and prevention, user management, authentication, authorization, and encryption mechanisms are employed across tiers and network zones. Defense in depth is compatible with perimeter security in that network perimeters (or more generically, protection zones) can make up part of the defense in depth strategy.

• Question 106:

  Your company has decided to create an Enterprise Architecture following. The Open Group Architecture Framework (TOGAF). Which option best describes how the IT Strategies from Oracle (ITSO) library of material relates to this TOGAF-based Initiative?

  A. ITSO has minimal applicability because TOGAF is a complete architecture framework.
  B. The ITSO material can be used as reference material within the TOGAF approach.
  C. The TOGAF approach will need to be modified (customized) to incorporate the ITSO material.
  D. The ITSO material will need to be adapted to the TOGAF approach.
  E. TOGAF and ITSO are mutually exclusive. One or the other must be chosen as the basis for the company's Enterprise Architecture.
  A. ITSO has minimal applicability because TOGAF is a complete architecture framework.

  ---

  The ITSO, and, being part of it, the Oracle Reference Architecture is not an Architecture Framework. For this, many solutions are already available, of which TOGAF andOracle's Enterprise Architecture Framework (OEAF) are good examples. The ORA can be perfectly integrated in any of the currently available frameworks.

  Note: The IT Strategies from Oracle give you a whole library of whitepapers, not only to develop a Reference Architecture for your own, by adapting the ORA to your needs, but it also focuses on the surrounding Enterprise Technology Strategies and Enterprise Solution Designs. In other words, ITSO covers both the horizontal technology perspectives (SOA, BPM, EDA, etc.), but also the vertical business perspectives (Utilities, Government, etc.).Now, in case you think that this is all about Oracle Technology products, you might be surprised: the whole ITSO / Oracle Reference Architecture is Vendor-Neutral. It is only scoped to Oracle's product portfolio. Now, one might ask themselves: what technology product area's doesn't Oracle have products for, so that shouldn't be too much of an issue as far as completeness is concerned.ITSO can help you organizing complex product landscapes, by means of a holistic approach to technology adoption. By covering the technology as a whole, you can reduce risk and become more in control of your IT solutions.

• Question 107:

  Which statements are correct for service contracts?

  A. Each SOA Serviceincludes a service contract.
  B. When using web services, the WSDL for the web service is the service contract.
  C. A service contract defines the functional and non-functional capabilities provided by an SOA Service.
  D. A service contract defines which clients are allowed to access a particular SOA Service.
  E. A service contract is optional documentation that might be provided for an SOA Service.
  A. Each SOA Serviceincludes a service contract.
  C. A service contract defines the functional and non-functional capabilities provided by an SOA Service.

  ---

  A: All Services must have a contract that adheres to a predefined template.

  C: A contract describes the Service in human-readable terms, enabling a solution designer to determine its capabilities and characteristics. It includes both functional and non-functional terms. The functional aspect of a contract describes the available operations of a Service and their functional capabilities. It should be stated using business terms, in order to promote alignment of Services to business concepts. Contracts also specify non-functional aspects of Service, such as invocation protocols, security requirements, semantics, transaction requirements, invocation style, quality of Service, etc.

• Question 108:

  Which statement best describes the reason why the Oracle Reference Architecture defines both a Service Contract and a Usage Agreement?

  A. The Usage Agreement is a reusable portion of the Service Contract that can be shared by other Service Contracts.
  B. The Usage Agreement defines how to use the SOA Service. The Service Contract defines the functionality provided by the SOA Service.
  C. The Service Contract is the reusable portion of the Usage Agreement that can be shared by other Usage Agreements.
  D. Defining both Usage Agreement and Service Contract provides a decoupling between service consumers and service providers.
  E. The Service Contract defines the technical specifics of the SOA Service. The Usage Agreement defines the business aspects of the SOA Service.
  D. Defining both Usage Agreement and Service Contract provides a decoupling between service consumers and service providers.

  ---

  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.

• Question 109:

  You are developing an Integration component that uses customer data. The source system defines customer data in a different format than expected. Which of the following options best describes how you would develop the component?

  A. Create an object representation of customer data and use itin the component.
  B. Externalize the data transformation by mapping the source data format to a canonical data format.
  C. The data formats are different, so it is not possible to develop the component.
  D. Write data from the source system into a database and read it back in the expected format.
  A. Create an object representation of customer data and use itin the component.

  ---

  Note:

  It is quite common to encounter use cases that require transformation of information from one format to another, especially in the area of enterprise integration. Source systems and target systems may use very different representations of

  data and in some cases, a canonical data model might be used as a common intermediate format. In some cases, the transformation is a simple field-to-field mapping whereas in other cases it is a complex manipulation and conversion of

  data. It should be possible to visually map the source and target representations with the ability to enrich the elements to support both simple and complex data transformations.

• Question 110:

  Oracle Reference Architecture uses multiple views (as defined by standard IEEE 1471) to describe the architecture. Which statement best describes the use of views within ORA?

  A. Each view within ORA focuses on a particular set of Oracle products.
  B. ORA provides multiple views (for example, Conceptual, Logical, Deployment) to describe the architecture to various stakeholders.
  C. Each view within ORA focuses on a particular set of industry standards.
  D. ORA provides multiple views (for example, Product Mapping, Deployment) to illustrate how Oracle products must be installed and configured.
  E. ORS uses views to illustrate industry standards and document architecture guidelines.
  B. ORA provides multiple views (for example, Conceptual, Logical, Deployment) to describe the architecture to various stakeholders.

  ---

  It is important that the service-oriented reference architecture documents the architecture from multiple views. Each view might include multiple models to illustrate the concepts, capabilities, etc. important for that view. The particular choice of views depends on what material is being covered and which views best convey the information. Example views include conceptual, logical, product mapping, and deployment views.
