The Open Group OG0-092 Exam - Topic 1 Question 37 Discussion

Question

Scenario: Zephyr EnterprisesPlease read this scenario prior to answering the questionZephyr Enterprises specializes in the development of wind turbine blades for use in large-scale commercial wind energy production systems. Zephyr has manufacturing facilities located in Palm Springs, California, Omaha, Nebraska, and Winnipeg, Ontario. Each of these plants supplies a different manufacturer that builds and sells complete systems. The turbine blades are custom engineered to meet each manufacturers design specifications.Until recently, most turbine blades were fabricated manually using molded fiber-reinforced plastics. However, recent improvements in composite materials, coupled with enhanced automated methods for precision application of materials during the molding process, have led to significant reduction in weight, increase in strength, and greatly improved blade longevity. Zephyr has pioneered the development of a proprietary automated process for continuous extrusion of the turbine blades. Patents have been filed to protect the process, but certain trade secrets must be closely guarded.Zephyr has a mature Enterprise Architecture organization that is supported by a cross-functional Architecture Review Board. The Chief Information Officer and the Chief Operating Officer co-sponsor the Enterprise Architecture program.Zephyr has used TOGAF and its Architecture Development Method (ADM) to develop its automated manufacturing processes and systems that are used to design, manufacture, and test the blade assemblies. They have recently updated to TOGAF 9 and have adapted the Zephyr Enterprise Architecture to closely follow the TOGAF 9 framework. All of Zephyrs IT architects have been trained and certified on TOGAF 9.Recently, an architecture project was completed that defined a standard approach for controlling the Automated Test System that is used at each plant to perform final quality assurance tests on each completed blade assembly. The Manufacturing Architecture Board approved the plan for immediate implementation at each plant.An Architecture Contract was developed that detailed the work needed to implement and deploy the new Automated Test System controller. The Chief Engineer, sponsor of the activity, has expressed concern that a uniform process be employed at each site to ensure consistency.Refer to the Zephyr Enterprises ScenarioYou have been assigned by the Lead Architect for the Automated Test System controller project to conduct Compliance Assessments at each manufacturing plant.During the course of the assessment at the Omaha plant, you discover that the Distributed Data Acquisition System they have purchased uses a proprietary Remote Procedure Call (RPC) that utilizes kernel mode threads instead of the user mode threads that are specified in the Architecture Definition Document. In all other respects, the system meets the requirements stated in the Architecture Definition Document and seems to perform correctly.You have been asked to describe the compliance of this system for the final report.Based on TOGAF 9, which of the following is the best answer?

Kattie · Accepted Answer

D) You observe that the system meets most of the requirements stated in the Architecture Definition Document and appears to work correctly. However, you note that the RPC mechanism has not been implemented according to the specification. Your recommendation is that the system be described as non-conformant.

Kattie · Answer

A) You observe that all of the features in the Architecture Definition Document have been implemented in accordance with the specification, except for the RPC mechanism. Your recommendation is that the system be described as conformant.

Kattie · Answer

B) You observe that the system has many features in common with the Architecture Definition Document, and those features have been implemented in accordance with the specification. However, you note that the RPC mechanism has been implemented using features that are not covered by the specification. Your recommendation is that the system be described as consistent.

Kattie · Answer

C) You observe that the implementation of the RPC mechanism has no features in common with the Architecture Definition Document, therefore the question of its conformance should not be considered. Your recommendation is that the system be described as consistent.
