Oracle 1Z0-574 Online Questions & Answers

• Question 171:

  Which statement best describes the relationship between the Oracle Reference Architecture (ORA) and Service-Oriented Architecture (SOA)?

  A. ORAincludes many different technology perspectives (for example, BPM, BI) Including SOA. The SOA perspective provides a view of ORA focused on the products and technology applicable to SOA.
  B. ORA embraces service orientation as a core tenet to consistently and uniformly deal with the complexity of a heterogeneous computing environment common to enterprise IT.
  C. ORA embraces SOA as a core tenet; therefore, adopting ORA means that SOAis adopted as well.
  D. ORA is a reference architecture based on architecture principles and best practices. SOA is a marketing term that has become widely and ambiguously used within the industry.
  E. SOAis an architectural approach that isproduct- and vendor-independent,ORA is essentially a SOA implemented using Oracle products and technology.
  B. ORA embraces service orientation as a core tenet to consistently and uniformly deal with the complexity of a heterogeneous computing environment common to enterprise IT.

  ORA does have a special relationship with SOA. ORA embraces service-orientation as a core tenet to improve agility, rationalize functions and data, and promote reuse in an effective manner. The entire strategy of SOA is not core to ORA

  (not C), but the concept of exposing data and functionality as interoperable SOA Services is core to ORA.

  ORA must provide interoperability across all Oracle products and must also effectively deal with the heterogeneity that exists in IT environments. SOA Services provide a clean, consistent approach to deal with both of these complexities. This

  is the reason that ORA includes service orientation as a core tenet.

  Stated as an architecture principle, this becomes:

  * The architecture embraces services as the primary mechanism for interoperability and integration.

• Question 172:

  How is state typically managed in the browser interface?

  A. generally through the use of cookies in the browser
  B. in the caching layer
  C. State is not managed. All modern UIs are stateless.
  D. The services tier manages state and the client tier is stateless.
  B. in the caching layer

  ---

  The State Management component is responsible for maintaining the current state of the user interface. For browser interfaces, this is frequently implemented via cookies.

• Question 173:

  Which of the following are capabilities provided by the Monitoring Engine within the Logical view of the Management and Monitoring architecture?

  A. Resource Monitor
  B. System Monitor
  C. Collection Monitor
  D. Service Monitor
  A. Resource Monitor
  B. System Monitor
  D. Service Monitor

  ---

  Logocal View, Monitoring Engine:

  

  Note:

  The Monitoring Engine contains a number of monitoring sub-systems which respond to scheduled events, and specific user actions within the management console in making various requests for data to be collected from various managed

  targets. In addition, these monitoring sub-systems integrate with each other to offer the administrator full discovery and drill down capabilities.

• Question 174:

  Which of the following are capabilities required for the Integration subsystem of the Oracle Reference Architecture Management and Monitoring Framework?

  A. Data Exchange
  B. Extensibility Framework
  C. Patch Monitoring
  D. Alert and Notification Integration
  E. Reporting
  A. Data Exchange
  B. Extensibility Framework
  D. Alert and Notification Integration

  ---

  Key integration capabilities:

  *

  Data Exchange

  *

  Extensibility Framework

  *

  Alert and Notification Integration Note: While it is preferable to have a single management and monitoring solution it is unrealistic that a single management and monitoring framework can support every available infrastructure component now and in the future. Two-way integration capabilities that cater for message exchange, bulk data exchange and extending the framework are key in addressing the needs of the modern IT environment.

• Question 175:

  Which of the following are strategies for alert management with Oracle Enterprise Manager?

  A. controlling the volume of alerts
  B. removing unwanted alerts
  C. centralized filtering of alerts
  D. automating fix for common alerts
  B. removing unwanted alerts
  D. automating fix for common alerts

  ---

  B: New in Enterprise Manager 10g Release 5 (10.2.0.5)

  Alert Management Enhancements: Administrators can better manage their log-based alerts (e.g., alert log alerts) by setting duration-based notification rules that clear such alerts on a periodic basis, or by using new EMCLI verbs that support

  bulk clearing of such alerts.

  D: New in Enterprise Manager 10g Release 5 (10.2.0.5)

  Alert Management Enhancements: On-demand evaluation of alerts allow administrators to quickly verify whether the fixes implemented for alerts result in clearing of the alert.

  Note: Advanced alert management

• Question 176:

  Which of the following token profiles is not included in the WS-Security standard as a standard type of identity token?

  A. XACML token profile
  B. SAML token profile
  C. username token profile
  D. Kerberos token profile
  E. X.500 token profile
  A. XACML token profile

  ---

  TheWS-Securityspecification allows a variety of signature formats, encryption algorithms and multiple trust domains, and is open to various security token models, such as:

  *

  X.509 certificates (not E)

  *

  Kerberos tickets (not D) *UserID/Password credential (not C)

  *

  SAML Assertions (not B) *custom-defined tokens.

  Note: WS-Security (Web Services Security, short WSS) is a flexible and feature-rich extension to SOAP to apply security to web services. It is a member of the WS-* family of web service specifications and was published by OASIS.
