Correct Answer: C

Explanation:

The Oracle Reference Architecture is Applicable to heterogeneous environments. It is independent of

specific products or version.

Correct Answer: ABD

Explanation:

Note E: BPM processes and sub-processes can (but are not required) themselves be exposed as SOA Services. This enables processes to be composed of SOA Services that are implemented as processes. It can be beneficial in two ways. First, it improves reuse of lower level system-centric processes (i.e. service orchestrations), and second, it offers a standard interface mechanism with which to invoke all types of business processes.

Note: BPM and SOA are often used together, as they both support a closer alignment between business and IT, and they both promote agility. BPM targets alignment and agility at the process level, while SOA applies more at the activity level. Hence, business processes and SOA Services can represent business constructs, providing a mapping between the things business does and the way IT helps get it done. The convergence of BPM and SOA generally happens via process decomposition. That is when business processes are modeled as, (i.e. decomposed into), activities. All automated activities must be backed by some form of executable code or function call. These functions, if they are deemed worthy, can be engineered as SOA Services following service-oriented design principles. Agility at the process level is attained by changing the process model. Agility at the service level is achieved by deploying services that are loosely coupled and independently managed.

Correct Answer: A

Explanation: 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.

Correct Answer: CE

Explanation:

A group is a set of users, classified by common trait. A role is an abstract name for the permission to

access a particular set of resources in an application.

Multiple users can be mapped to a role.

Users can be mapped to multiple roles.

Incorrect answers

A, B: Just wrong.

D: A group is a collection of users, but a role does not need to be a collection of groups.

Note: Given the potentially large number of users of a system, access privileges are generally not assigned at the user level. Instead, users are assigned to groups (mimicking the organizational structure of a company), or roles (defined based on job functions that users perform), or some combination of the two. Access privileges are then assigned to groups and/or roles. The most natural case is that they are assigned to roles, since roles align more closely with operations users naturally perform to accomplish their job. The industry term for this is Role-Based Access Control (RBAC). RBAC is more flexible than defining access rights based on usernames or static groups and enables an organization to be more versatile when allocating resources. With RBAC the system must determine if the subject (user or client) is associated with a role that has been granted access to a resource. This process of user to role ascertainment is called role mapping.

Correct Answer: B

Explanation: Symmetrickey cryptography uses the same key to encrypt and decrypt data. Therefore the sender and receiver must each have a copy of the key. It is important that no other entity gains access to the key otherwise they would be able to decrypt the data as well. Common key algorithms include the Data Encryption Standard (DES), Triple DES (3DES), and Advanced Encryption Standard (AES).

Correct Answer: B

Explanation:

The architecture must provide rapid, guided development of the user interface without needlessly exposing

the developer to implementation details.

Reducing the time and resources required to deliver business solutions is required for IT to better support

and align with business needs. Low level development is both time consuming and error prone.

Correct Answer: B

Explanation:

To define a framework that meets both the management and monitoring requirements and the architecture

principles, one might consider the framework to be comprised of four major parts (User Interaction,

Management, Monitoring, and Integration) that complement other ORA components (ORA Engineering,

ORA Security). The framework utilizes a management repository for storage of all current and historical

data and metadata.

Correct Answer: DE

Explanation:

D: This type of deployment easily supports acquisitions since a new acquisition can be treated as simply another portfolio. E (not F): The primary disadvantage of a hierarchical deployment is the increased cost and complexity of supporting more hardware and software. Adherence to standards to support interoperability is also more important in a hierarchical deployment since the various portfolios may select different products

Correct Answer: B

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.
