There are various network topologies that can be used when deploying the Service-Oriented Integration architecture. One deployment option includes three networks: production network, services network and maintenance network. Which statement best describes the uses of these three networks?
A. The production networkisused for all production network traffic. The services networks is used to deploy and configure SOA Services. The maintenance network is used by the operations team to manage the infrastructure.
B. The production network provides connectivity to applications and client access to the Mediation Layer. The services network provides connectivity between the Mediation Layer and the SOA Services. The maintenance network is used by the operations team to manage the infrastructure.
C. The production network provides connectivity to applications and client access to the Mediation Layer-The services networks is used to deploy and configure SOA Services. The maintenance network is used by the operations team to manage the infrastructure.
D. The production network is used for all production network traffic. The services network provides connectivity between the Mediation Layer and the SOA Services. The maintenance network is by the operations team to manage the infrastructure.
E. The production network is used for all production network traffic. The services networks is used to deploy and configure SOA Services. The maintenance network is trusted network, providing administrator access to all hardware and software.
Enterprise Architecture consists of Business Architecture, Application Architecture, Information, Architecture and Technical Architecture (BAIT). Which statement best describes Oracle Reference Architecture (ORA) in the context of BAIT?
A. ORA addresses all four (Business, Application, Information, and Technical) equally.
B. ORA is primarily focused on the Technical Architecture, with some content on the other three aspects-of BAIT.
C. ORA has content applicable to the Technical Architecture only.
D. ORA is primarily focused on the Business Architecture, with some content on the other three aspects of BAIT
E. ORA is primarily focused on the information Architecture, with some limited content on the other three aspects of BAIT.
F. ORA has content applicable to Information Architecture only.
The Service-Oriented Integration (SOI) architecture includes an event-handling capability as illustrated and described in the Process View. Which statement best describes the rationale for including event handling in the SOI architecture?
A. Event-Driven Architecture (EDA) is a subset of SOI, so including event handling provides the EDA part of SOI.
B. The event-handling capability allows arbitrarily complex events to be handled by the architecture;
C. e. Complex Event Handling (CEP) is part of the SOI architecture.
D. AH other interactions within the architecture are upper layers calling lower layers. The event- handling capability allows a Connectivity Service to call a Business Service, thus providing the ability to lower layers to call upper layers in the architecture.
E. The event-handling capability allows a back-end system that is included in the SOI to initiate action because something important has occurred within the back-end system.
F. By employing a publish-and-subscriber message approach, the event-handling capacity allows the SOI architecture to handle high-volume message traffic because publish-and-subscribe handles higher message volumes than request-response.
You need to redesign your application to improve performance. The potential solution requires the data to be kept in memory for faster access. The in-memory data requires full support for SQL with BI queries and there is no need to scale out further. Which Oracle product would you choose to implement your solution?
A. Oracle Coherence
B. Oracle TimesTen
C. Oracle TUXEDO
D. Oracle VM
Which of the following is not a valid type of SAML assertion?
A. authentication assertion
B. authorization decision assertion
C. audit assertion
D. attribute assertion
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.
You are working with an IT department that has embraced Service-Oriented Integration (SOI). The development team has created a catalog of services that rigidly follow the layering of the SOI architecture as illustrated by the Logical View. Clients are allowed to call only Business Process Services, Business Process Services only call Business Services, Business Services only call Data Services, and so on, with each call going through the Mediation Layer. Unfortunately, the quality assurance team has discovered during user acceptance testing that the latency of applications the Business Process Services is unacceptable.
What advice would you give the development team to help reduce the latency without sacrificing adherence to the SOI architecture?
A. Change the SOA Services to bypass the Mediation Layer when calling other SOA Services. The Mediation Layer should be used only between the clients and the SOA Services. The Mediation Layer should not be used between SOA Services.
B. The developers are accurately following the SOI architecture. Reducing the latency will require that some of the SOI architecture concepts be relaxed or violated.
C. Remove all data transformation from the Mediation Layer because data transformations are too computationally expensive, where required, change the interface of the SOA Services to use a single data model so that data transformations are not needed.
D. Allow clients and SOA Services to use large-granularity operations. Each operation on the Business Process Service should return an entire data entity or multiple data entities. This reduces the number of client calls required and, therefore, the overall latency.
Which principle should be applied when considering display devices?
A. The architecture must provide distinct tooling for the unique development of every available device.
B. The architecture must support translation of standard browser code to all possible variations of display devices, allowing the developer to focus on functionality for the end user.
C. The architecture must provide for the development of user Interfaces for a variety of display devices.
D. Only display devices that support a full-featured user interaction are allowed with this architecture.
What is meant by cache hit rate or ratio?
A. the percentage of times the cache was hit successfully over the total number of tries
B. the percentage of times the cache was refreshed from the back-end database
C. the number of servers the cache is replicated to
D. the ratio of cache objects in a server to the total number of cache objectsin the server cluster
Which of the following standards states that every reusable asset must contain a minimum of one manifest file and at least one artifact to be considered a valid reusable asset?
A. OMG Reusable Asset Specification (RAS)
B. OMG Meta Object Facility (MOF)
C. OMG XML Metadata Interchange (XMI)
D. OMG Systems Modeling Language (SysML)
