Q73. Which of the following are the key drivers for Grid computing?
A. Improved server utilization - Grid computing allows companies to lower costs through the efficient use of resources.
B. Better agility and flexibility - Businesses experience constant change and the underlying IT Infrastructure should be agile enough to support that kind of change.
C. OpEx model - Enterprises require pay-as-you-go services to reduce the dependency on capital expenditure and take advantage of the benefits of operational expenditure.
D. Lower Initial cost-There is a need to reduce the Initial investment at the cost of an increased operational cost.
Answer: A,B,D
Explanation: 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.

Q74. What does access to Consolidated Information in Complex Distributed Environments require?
A. siloedIT management and monitoring tools such as event managers and network managers.
B. architects and engineers to reverse engineer applications to determine dependencies across components
C. Access to information concerning dynamicinterdependences acrossinfrastructurecomments.
D. Following for diagnosing and correlating problems in complex, distributed environments.
E. a strong bottom-up approach to IT management to focus on the status of individual low-level Infrastructure components
Answer: C
Explanation: Infrastructure components have become more dependent on one another, with many of these interdependencies crossing corporate boundaries. Without access to information concerning these dynamic interdependencies, diagnosing and correlating problems in a complex, distributed environment is a huge challenge.

Q75. Which of the following are the three major tiers of the Logical view of the Oracle Management Reference Architecture?
A. Administrative Tier
B. Client Tier
C. Management Tier
D. Managed Services Tier
E. Managed Target Tier
Answer: B,C,E
Explanation: * The Client Tier represents access to management content and operations as well as end users accessing the appropriate business solution. Administrators utilize a browser based console to perform their management tasks using a standard browser interface. The management console which is lightweight, easy to access and firewall friendly, enables administrators to centrally manage their entire environment.
* The Management Tier renders the content and interface for the management console that gives access to management operations such as monitoring, administration, configuration, central policy setting, and security. The Management Tier controls the accessing and uploading of management information.
* The Managed Target Tier contains the named infrastructure components that are required to be managed and monitored. It is common to utilize a combination of agent based and gateway (a.k.a. proxy) patterns to monitor and manage hosted and non-hosted targets.

Q76. Which of the following are primary parts of a SOA Service as defined by the Oracle Reference Architecture?
A. Service Contract
B. Usage Agreement
C. Service Infrastructure
D. Service Implementation
E. Service Interface
F. Web Services Description Language (WSDL)
Answer: A,D,E
Explanation: The three primary parts of a SOA Service as defined by ORA are contract, interface, and implementation.
Note:
A Service Contract describes the SOA Service in human-readable terms.
The Service Implementation is the technical realization of the contract. I
A Service Interface provides a means for the consumers of a SOA Service to access its functionality according to the Service Contract.

Q77. Which of the following statements are true about applying security to SOA Services?
A. SOA Services must base access control decisions on roles, attributes, rules, and so on, that are universal to all consumers.
B. SOA Services are difficult to secure due to a lack of security standards for Web Services.
C. SOA Services are a type of monolithic application with self-contained identity and role management.
D. Data returned by a SOA Service may need to be redacted according to data classification schemes, depending on the privileges of users.
Answer: A,D
Explanation: A: In terms of access control, SOA Services must base access control decisions on roles, attributes, rules, etc. that are universal to all consumers.
D: data provided by a SOA Service must adhere to data classification restrictions that might differ between consumers. For instance, the same query service may need to redact various rows or columns of data based on restrictions assigned to classes of consumers.

Q78. 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.
Answer: A
Explanation: Oracle Reference Architecture(ORA) defines a detailed and consistent reference architecture for developing and integrating solutions based on current technologies from Oracle and other vendors. The reference architecture offers architecture views, 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.
Q79. Which statements are correct with regard to the layers in the Logical View of Service-Oriented Integration (SOI)?
A. Upper layers in the architecture leverage capabilities provided by lower layers.
B. Upper layers are allowed to access capabilities in any lower layer.
C. Upper layers are allowed to access capabilities only in the next lower layer.
D. Each layer encapsulates specific capabilities required by the entire architecture.
E. Each layer encapsulates optional capabilities of the architecture; thus any layer can be omitted from the architecture.
F. The layers are used to partition the capabilities of the architecture, but otherwise have no architectural significance.
Answer: A,C,D
Explanation: Each layer encapsulates specific capabilities for the overall architecture. Upper layers in the architecture leverage the capabilities provided by the lower layers. Generally, upper layers call lower layers in the architecture and the reverse (i.e. lower levels calling upper layers) is prohibited.

Q80. DES, 3DES and AES are types of:
A. message digest algorithms
B. symmetric key algorithms
C. asymmetric key algorithms
D. SSL identity tokens
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).
