• Question 71:

  The principle of "Security as a Service" states that business solution; must be designed to consume common security services, where possible, as opposed to implementing custom security logic and replicating copies of security data. Which of the following statements is not an Implication of this principle?

  A. Security logic must be externalized as much as possible, i.e., developers must not hand-code security logic into business solutions.
  B. Security enforcement, decisions, and management must be performed by dedicated, shared services and Infrastructure.
  C. Wherever possible, security services must be built upon open standards.
  D. Security services must use Web Service (SOAP) interfaces and XML payloads in order to promote Interoperability.
  A. Security logic must be externalized as much as possible, i.e., developers must not hand-code security logic into business solutions.
  B. Security enforcement, decisions, and management must be performed by dedicated, shared services and Infrastructure.
  C. Wherever possible, security services must be built upon open standards.

  ---

  Rationale: Security services allow multiple solutions to share common security logic, features, policies, and identity information. This provides a more secure environment by eliminating redundancies and associated risks. It also enables more

  effective management of security in the IT environment.

  Implications:

  *

  Security logic must be externalized as much as possible, i.e., developers must not hand-code security logic into business solutions.(A)

  *

  Security enforcement, decisions, and management must be performed by dedicated, shared services and infrastructure.(B)

  *

  Security services must leverage open standards for interface protocols and message formats where possible in order to promote interoperability.(C)

  *

  The availability and performance characteristics of security services must meet or exceed the specifications required to support the business solutions.

• Question 72:

  A customer has two separate lines of business and each has its own unique resources that are controlled independently. The customer wants to provide a single user interface at the enterprise level that, at least from the user's perspective, unifies the separate lines of business and presents a single consistent view. What is the most suitable architectural arrangement for such a federated deployment?

  A. The enterprise implements full client stack and part of the service stack while each LoB deploys the remaining part of the service tierin order to expose uniform interface elements.
  B. The client tier assimilates the data from the resource stack of each line of business.
  C. The enterprise implements full client and service stacks while each LoB deploys a partial service. sufficient to expose uniform interface elements.
  D. The client tier assimilates the data from the service stack of each line of business.
  A. The enterprise implements full client stack and part of the service stack while each LoB deploys the remaining part of the service tierin order to expose uniform interface elements.

  ---

  Each line of business has its own resources that are unique to the line of business and are controlled by that line of business. The enterprise wants to provide a single user interface that, at least from the user's perspective, unifies the separate lines of business. In this example, the enterprise wide user interface deployment is a full featured user interaction architecture (i.e. it contains all of the capabilities defined in the Logical View). Each line of business deploys limited functionality since the only functionality required is the functionality to create interface elements exposing the resources of that line of business. The enterprise wide user interface then uses the interface elements provided by the lines of business to create a unified user experience. The interface elements provided by the lines of business are Remote Providers to the enterprise user interface. This deployment allows the lines of business to maintain control of their respective resources since the only access to the resources is via the interface elements that they create.

• Question 73:

  Which product provides the standard communication protocols (for example, HTTPS) between 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
  A. Oracle platform Security Services

  ---

  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.

• Question 74:

  A modular approach has been taken to document the Oracle Reference Architecture (ORA). Select the statements that are true for this modular approach?

  A. The ORA library has a document dedicated to each Oracle product suite.
  B. ORA is a collection of reference architectures, some based on specific technologies (Technology Perspectives), and some on industry verticals (Industry Perspectives).
  C. ORA is a single-reference architecture but is documented via different views of the architects-some focused on specific technologies (Technology Perspectives), and some on industry verticals (Industry Perspectives).
  D. The number of Technology Perspectives and Industry Perspectives will increase over time.
  E. The technology Perspectives are complete, but the Industry Perspectives will increase over time as more verticals are Included.
  A. The ORA library has a document dedicated to each Oracle product suite.
  C. ORA is a single-reference architecture but is documented via different views of the architects-some focused on specific technologies (Technology Perspectives), and some on industry verticals (Industry Perspectives).
  D. The number of Technology Perspectives and Industry Perspectives will increase over time.

  ---

  A: The scope of ITSO is all of Oracle's product families. However, the Oracle technology real estate is extremely large and evolves as new products are introduced. Thus, the ITSO material will continue to grow as more ORA documents are created, additional ETSs are covered, and additional ESDs are created. C, D:Technology perspectives extend the core material by adding the unique capabilities, components, standards, and approaches that a specific technology strategy offers. SOA, BPM, EPM/BI, and EDA are examples of perspectives for ORA. Each technology strategy presents unique requirements to architecture that includes specific capabilities, principles, components, technologies, standards, etc. Rather than create another reference architecture for each strategy, ORA was designed to be extensible to incorporate new computing strategies as they emerge in the industry.

  In order to present the reference architecture in the most effective manner, each new technology strategy adds a perspective to ORA. This enables the reference architecture to evolve holistically. New computing strategies extend the core material, providing further insight and detail as needed. A perspective extends the ORA core collateral by providing views, principles, patterns, and guidelines that are significant to that technology domain yet cohesive with the overall ORA. The perspective includes:

  *

  A foundation document describing the terms, concepts, standards, principles, etc. that are important to the ETS.

  *

  An infrastructure document that defines a reference architecture built using the technologies pertinent to the ETS.

  An industry reference architecture is a set of high level architectural representations which characterize the current state architecture of an enterprise and a desired state, or architectural vision, based on the ORA.

• Question 77:

  You are designing a mission-critical application that requires high performance. Your analysis concludes that Oracle Exadata would enable you to meet the performance goals. What characteristics of Oracle Exadata make it possible to provide such superior performance?

  A. Oracle Exadata uses massively parallel architecture to speed up Oracle data warehouses by offloading data-intensive query processing from the databases.
  B. By pushing SQL processing to the Oracle Exadata Storage Server, all the disks can operate in parallel, reducing database server CPU consumption while consuming much less bandwidth to move data between storage and database servers.
  C. The Oracle Exadata Storage Server returns a query result set rather than entire tables, eliminates network bottlenecks, and frees up database server resources.
  D. Oracle Exadata uses direct data placement to ensure very low CPU overhead by directly moving data from the wire to database buffers with no extra data copies being made.
  A. Oracle Exadata uses massively parallel architecture to speed up Oracle data warehouses by offloading data-intensive query processing from the databases.

  ---

  To overcome the limitations of conventional storage, Oracle Exadata Storage Servers use a massively parallel architecture to dramatically increase data bandwidth between the database server and storage. Innovative technologies such as Exadata Smart Scan, Exadata Smart Flash Cache, and Hybrid Columnar Compression enable Exadata to deliver extreme performance for everything from data warehousing to online transaction processing to mixed workloads.

• Question 78:

  Which statement best describes the use of point-to-point integrations within a Service-Oriented Integration (SOI) architecture?

  A. point-to-point integrations using web services are an Integral part of SOI and should be used extensively.
  B. Only web service-based point-to-point integrations are allowed (but discouraged).
  C. Point-to-point integrations should be avoided but are allowed as exceptions when requirements can be met only by point-to-point integration.
  D. Point-to-point integrations are brittle and expensive to maintain and therefore should never be used.
  C. Point-to-point integrations should be avoided but are allowed as exceptions when requirements can be met only by point-to-point integration.

  ---

  Avoid Point-to-Point Integrations. Point-to-point integrations are brittle, inflexible, and expensive to maintain. There are cases where point-to-point integrations are required but these should be handled as exception cases. Example exceptions include performance requirements that can only be met using point- to-point connections and when large amounts of data must be moved.

• Question 79:

  The WebShipAnywhere company currently has a manual Order-to-Ship process. The company is implementing Service-Oriented Integration architecture and, as part of that initiative, they are automating the Order-to-Ship process.

  Whenever an order ships, the Warehouse Management System (WMS) is manually updated to reflect that the order has been shipped. If the Inventory for any product that was part of the order drops below a threshold value, the WMS alerts the user via a pop-up screen indicating that the product inventory is low. When this happens, the user logs in to the Purchasing System (PS) and enters the need to order more of the product. Both the WMS and PS are thick-client, two-tier applications that use an Oracle database. As part of automating the Order-to-Ship process, the company would like to remove this manual step. What integration pattern(s) should be used to automate this manual step?

  A. The WMS should be modified to create a "low-inventory" event and publish the event to a topic queue following the publish-and-subscribe pattern. An event handler registered for the "low-inventory" event then receives the event and updates the PS.
  B. The polling integration pattern should be used to detect that the inventory for a product is low in the WMS. If a product inventory is low, the polling component uses a reliable-one-way message to call an SOA Service that updates the PS.
  C. It is not possible to integrate thick-client, two-tier applications (such as VMS and PS) by using a SOI architecture. Only applications with service interfaces can be included in an SOI architecture
  D. The polling integration pattern should be used to detect that the inventory for a product is low in the VMS. If a product inventory is low, a "low-inventory" event should be created and published to a topic queue following the publish-andsubscribe pattern. An event handler registered for the "low inventory" event then receives the event and updates the PS.
  E. Because both the WMS and the PS use Oracle database, the WMS should be modified to use a trigger to update the PS database whenever a low inventory is detected.
  B. The polling integration pattern should be used to detect that the inventory for a product is low in the WMS. If a product inventory is low, the polling component uses a reliable-one-way message to call an SOA Service that updates the PS.

  ---

  Polling, using a reliable-one-way message, and using a SOA Service is a good solution.

• Question 80:

  Bottom-up service Identification analyzes existing systems to Identify SOA Services. Top-down service identification analyzes business processes to identify SOA services.

  Which statement best describes the relationship between top down and bottom-up service identification in Service-Oriented Integration?

  A. Only a bottom up approach shouldbe used because the goal of SOIis to provide SOA Services exposing existing systems.
  B. Only a top-down approach should be used because the goal of SOI is composite application assembly.
  C. A bottom-up approach should be used to identify which SOA Services are built; then a top-down approach should be used to determine which SOA Services are used by each composite application.
  D. A top-down approach should be used to determine the needed SOA Services; then a bottom-up approach should be used to determine how existing source systems can meet the requirements top- down approach should be used by business, and a bottom-up approach should be used by IT.Theoverlap between the SOA Services Identified by the two methods are the ones that should

  Note: There are three schools of thought around "how to build an Enterprise Service Oriented Architecture." They are:

  *

  Top down - central group decides everything and the dev teams adopt them.

  *

  Bottom up - central group provides a directory and dev teams make whatever services they want. Dev teams go to the directory to find services they can use.

  *

  Middle out - central group provides key elements of the interface, including numbering schemes, message exchange patterns, standard communication mechanisms, and monitoring infrastructure, and encourages the dev teams to use it to build services that can be shared.
