Correct Answer: D

Explanation: IT Strategies from Oracle (ITSO) is a series of documentation and supporting material designed to enable organizations to develop an architecture-centric approach to enterprise-class IT initiatives. ITSO presents successful technology strategies and solution designs by defining universally adopted architecture concepts, principles, guidelines, standards, and patterns.

ITSO is made up of three primary elements Oracle Reference Architecture (ORA), Enterprise Technology Strategies (ETS) and Enterprise Solution Designs (ESD).

Enterprise Technology Strategies (ETS) offer valuable guidance on the adoption of horizontal technologies for the enterprise. They explain how to successfully execute on a strategy by addressing concerns pertaining to architecture, technology, engineering, strategy, and governance. An organization can use this material to measure their maturity, develop their strategy, and achieve greater levels of adoption and success. In addition, each ETS extends the Oracle Reference Architecture by adding the unique capabilities and components provided by that particular technology. It offers a horizontal technology-based perspective of ORA.

Explanation: Technology perspectives extend the core material by adding the unique capabilities, components, standards, and approaches that a specific technology strategy offers.(A) 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.

Correct Answer: AB

Explanation: Static modeling focuses on capturing the instance attributes and snapshots of nodes and objects. Dynamic modeling generally refers to one or both of the following

*

Behavior modeling that focuses on the internal state changes

*

Interaction modeling that focuses on external collaborations.

Note: Modeling is a prime and foremost activity of the engineering process. Modeling bridges the gap between business and technology worlds through the language common to both sides.

Explanation: Distributed computing provides a scalable runtime platform capable of handling many concurrent users by allowing related components to be spread out but at the same time enabling them to work in unison. It allows applications to be broken down into smaller, modular components and be deployed across a distributed infrastructure that leverages the power and flexibility of networked servers. Layered architecture enables separation of concern by defining individual logical layers that can be deployed independently, taking advantage of the distributed infrastructure. Distributed architectures allow selective scalability of the layers that require more capacity to handle the load. This allows efficient use of the hardware and software resources and optimization of performance by fine-tuning the appropriate layer or component. In contrast to some of the other models, distributed computing generally is a CAPEX model where the distributed infrastructure is built in-house for applications to be deployed.

Note: In distributed computing a program is split up into parts that run simultaneously on multiple computers communicating over a network. Distributed computing is a form of parallel computing, but parallel computing is most commonly used to describe program parts running simultaneously on multiple processors in the same computer. Both types of processing require dividing a program into parts that can run simultaneously, but distributed programs often must deal with heterogeneous environments, network links of varying latencies, and unpredictable failures in the network or the computers.

Note 2: Distributed computing allows multiple, autonomous computers to work in concert to solve a problem or provide a business solution. Distributed computing is used in the vast majority of modern enterprise business solutions.

Explanation:

A: The downside to TLS is that it only protects data in transit, or "point-to-point". Once data is received, it is

no longer protected.

B: Point to point security is often used as a

default or minimal security option in order to protect messages over insecure networks.

C:A lesser alternative to end to end security is point to point security. This is used to protect messages in

transit. It assumes that other means of security are used to protect messages during processing and

persistence.

Generally, less effort is made to protect data behind the corporate firewall. This opens up a number of

vulnerabilities and risks to an organization.

E: SSL/TLS is not so hard to set up. It is popular.

Correct Answer: B

Explanation:

In a write-through cache, every write to the cache causes a synchronous write to the backend store.

In this approach, the data is updated in the

backend data store, then the primary cache, all within the scope of the transaction. Then the backup cache

is also updated to maintain consistency of data.

Explanation:

OPSS is incorporated into OWLS which ties the entire Service Tier into the enterprise security architecture.

The OWC provides the majority of the capabilities required for a modern user interface. OWC provides

some higher-level Connectivity capabilities (e.g. connectivity to content management systems, WSRP).

OWLS provides the base Connectivity (e.g.

JDBC, JCA) to connect to the Resource Tier.

Note: Oracle WebLogic Suite (OWLS) - fully implements the latest Java EE standards, provides industry

leading reliability and performance, and includes comprehensive management capabilities. OWLS can be

used to host the Oracle WebCenter products.

Correct Answer: B

Explanation: The primary goal of user interaction is to provide a user-centric, feature-rich, intuitive interface to end users tailored to the specific needs of each end user; thereby bringing maximum productivity to the work environment. Realizing this goal requires a flexible, extensible architecture since different types of end users will have very different needs.

Explanation:

Like the Authenticator, theIdentity Assertersecurity provider uses Oracle Access Manager authentication

services to validate already-authenticated Oracle Access Manager users using the ObSSOCookie and to

create a WebLogic-authenticated session.

Note: If authentication is successful, the identity asserter creates a Subject, which is used to identify the

user. Actions performed by the user will be associated with the Subject so that the caller's identity will be

known. If outbound requests are made by the business logic, identity can be included by the container

based on the Subject.
