• Question 111:

  Which statement best describes the role of the Data Normalization Layer within the Logical view of the Service-Oriented Integration (SOI) architecture?

  A. The Data Normalization Layer converts all data formats to third normal form to facilitate database access.
  B. The Data Normalization Layer converts all data formats to XML to facilitate platform independent.
  C. The Data Normalization Layer hides the complexity of the multiple data formats used by back end systems by converting data to standardized formats.
  D. The Data Normalization Layer stores persistent data in a normalized format.
  E. The Data Normalization Layer provides normalized access to all databasesiIncluded as back-end systems in the architecture.
  C. The Data Normalization Layer hides the complexity of the multiple data formats used by back end systems by converting data to standardized formats.

  ---

  The Data Normalization Layer provides a standardized format for data entities. Each EIS stores data in its own (usually proprietary) format. This layer transforms the data to a form that is readily consumable by the upper layers in the architecture.

  The primary purpose of this layer in the architecture is to encapsulate and hide the complexity of the data models and formats used by the back-end systems. This allows the upper layers in the architecture to operate on data entities that match the needs of the business rather than operating on data that match the storage approach of the back-end systems.

The reference architecture offers architecture principles and guidance based on recommendations from Oracle product development architects and field experts. Information provided by ORA gives architects an understanding of how to design solutions for the Oracle environment and best leverage its capabilities.

  Note:Oracle Reference Architecture (ORA) defines a detailed and consistent architecture for developing and integrating solutions based on Oracle technologies. The reference architecture offers architecture principles and guidance based on recommendations from technical experts across Oracle. It covers a broad spectrum of concerns pertaining to technology architecture, including middleware, database, hardware, processes, and services.

• Question 115:

  How is Oracle Database Firewall (ODF) used to protect applications from attacks such as SQL- Injection?

  A. ODF is an option for the Oracle Database. A DBA configures this option to inspect database commands and compare them with a set of known attacks. An ODF agent periodically downloads the latest signatures in order to keep up with the latest known types of attacks.
  B. ODF is a feature of Oracle Advanced Security. A database security administrator configures each database realm with a set of acceptable ports and protocols from which database clients can connect. Valid connections are continuously monitored for suspicious activity.
  C. ODF is an agent based secure connection component that is installed on the database and on the clients. It creates a VPN-like connection between the two that greatly reduces the likelihood of man-in- the-middle and SQL-injection attacks. An administrator installs ODF and configures it for a specific environment.
  D. ODF is a stand-alone product that is installed in between the client and database. It monitors and/or blocks SQL statements, comparing them against a set of known good or known bad statements.
  D. ODF is a stand-alone product that is installed in between the client and database. It monitors and/or blocks SQL statements, comparing them against a set of known good or known bad statements.

  ---

  Oracle Database Firewall (ODF) - ODF is the first line of defense for both Oracle and non-Oracle databases. It monitors database activity on the network to help prevent unauthorized access, SQL injections, and other forms of attack. ODF uses positive (white list) and negative (black list) security models to validate SQL commands before they can reach the database. The ODF instances act as a firewall for incoming SQL traffic. Each instance can handle multiple downstream databases, and the instances are configured for high availability. SQL traffic must pass through the firewall boxes in order to reach the databases. ODF protects Oracle, MySQL, Microsoft SQL Server, IBM DB2 for Linux, Unix, and Windows, and Sybase databases

• Question 116:

  Much as in modular programming, there are two ways that federation applies to user interface design:

  A. As a consumer, the end user is responsible for incorporating existing Interface elements into the user interface.
  B. As a consumer, the device is responsible for incorporating existing Interface elements into the user interface.
  C. As a consumer, the developer is responsible for incorporating existing Interface elements into the user interface.
  D. As a producer, the developer is responsible for building separate and independent interface elements that can be incorporated into another user interface.
  E. As a producer, the developer is responsible for incorporating existing interface elements into the user interface.
  C. As a consumer, the developer is responsible for incorporating existing Interface elements into the user interface.

  ---

  As a consumer the developer is responsible for incorporating existing interface elements into the user interface.

  B. A common set of security services and information can be used across the organization, promoting Infrastructure reuseand minimizing inconsistencies.
  E. Interoperability amid federation are easier to achieve via the adoption of common security and technology standards.

  ---

  In order to provide security in a consistent manner, a common set of infrastructure, e.g. a security framework, must be used. The purpose of this framework is to rationalize security across the enterprise by:

  *

  Establishing a master set of security data that reflect the policies, IT resources, participants and their attributes across the entire domain of security

  *

  Mapping organizational structures, computing resources, and users to roles in a way that clearly depicts access privileges for the organization

  *

  Maintaining fine-grained access rules based on roles that have been established for the organization

  *

  Propagating the master security data to individual applications and systems that enforce security (A)

  *

  Detecting changes to security data residing on systems that have not been propagated from the master source of record, and sending alerts regarding these inconsistencies

  *

  Providing common security services, such as authentication, authorization, credential mapping, auditing, etc. that solutions can leverage going forward in place of custom-developed and proprietary functions (B)

  *

  Facilitating interoperability between systems and trust between security domains by acting as a trusted authority and brokering credentials as needed(E)

  *

  Centrally managing security policies for SOA Service interactions The security framework should provide these types of capabilities as a value-add to the existing infrastructure. The intent is not to discard the capabilities built into current applications, but rather to provide a common foundation that enhances security across the enterprise. Security enforcement can still be performed locally, but security data should be modeled and managed holistically.

  Incorrect:

  C: Not a main goal.

  D: Ease of administration and auditing is not a main goal here.

  Using a grid computing architecture, organizations can quickly and easily create a large-scale computing infrastructure from inexpensive, off-the-shelf components (D). Other benefits of grid computing include

  *

  Quick response to volatile business needs (B)

  *

  Real-time responsiveness to dynamic workloads

  *

  Predictable IT service levels

  *

  Reduced costs as a result of improved efficiency and smarter capacity planning (A) Note: One way to think about grid computing is as the virtualization and pooling of IT resources-- compute power, storage, network capacity, and so on--into a single set of shared services thatcan be provisioned or distributed, andthen redistributed as needed. As workloads fluctuate during the course of a month, week, or even through a single day, the grid computing infrastructure analyzes the demand for resources in real time and adjusts the supply accordingly.

  Grid computing operates on three basic technology principles: Standardize hardware and software components to reduce incompatibility and simplify configuration and deployment; virtualize IT resources by pooling hardware and software into shared resources; and automate systems management, including resource provisioning and monitoring.

  Grid computing operates on these technology principles:

  *

  Standardization.

  *

  Virtualization.

  *

  Automation.
