Question 108

Scenario

Please read this scenario prior to answering the Question

You are working as a consultant to the Chief Architect at an intelligence and security organization responsible for securing government communications and information systems. These provide real-time, highly secure communication of voice, video, and message data to remote locations around the world. The agency has recently received information from intelligence sources that the current encryption protocols may no longer be secure. In response, a program is underway to upgrade the systems.

The agency has an established Enterprise Architecture (EA) capability based on the TOGAF standard. The Executive Director of the agency is the sponsor of the EA capability.

Since reliable, high-performance, and secure communications are essential to preserving national security, the Executive Director has placed more stringent requirements for the architecture of the upgraded systems. It must be able to provide assurance and verification of specific performance measures on the key services that are most crucial for system operation. Focusing on these service-level details and specific measurements, will allow stricter requirements to be enforced in service contracts. It will also provide a high degree of assurance that necessary performance is being delivered and that notifications will occur if any critical service fails to perform as required.

A portion of the program budget has been allocated to context a review of the EA. The scope of the review is to evaluate the processes, content and governance of the EA capability to ensure that the higher target performance and service levels required by the upgraded system can be achieved.

The Chief Architect has noted that the core EA artifacts that have been in use are not able to describe these new capabilities. The artifacts do not have explicit provisions for defining the in-depth measurement requirements regarding specific services required for the system. She has learned that certain services within the current system have service measurement implementations that match some of the new requirements, but they are only used in a few areas.

Recent EA efforts at another national agency have produced generalized high-performance communication system models to realize similar requirements in a critical defense system involving secure communications. It is possible that these models may be useful for the upgrade program.

[Note: You may need to refer to the Content Metamodel chapter, section 30.4 (located in Part IV) of the reference text in order to answer this question.]

You have been asked to make recommendations for tailoring the Architecture Content Metamodel to accommodate the requirements of the upgraded system.

Based on the TOGAF standard, which of the following is the best answer?

Options:

You recommend that a Communications Engineering view is created using the infrastructure consolidation extension from the Architecture Content Metamodel. This view will allow architects to align the needed performance measurement communications across the system. This will support the stringent performance measurements needed for the more detailed governance views required for the upgraded system, making the interfaces to the communication

You recommend that the services extension be incorporated into the Architecture Content Metamodel. By using this extension, the service model is no longer constrained by what is expected in typical business service definitions, allowing more flexibility for adding customized models to support the more stringent measurement requirements. The services extension can also be used to map terminology between the business services and the applicat

You recommend that the motivation and governance extension are incorporated into the Architecture Content Metamodel. Using these extensions will allow modeling the goals, objectives and drivers for the architecture, linking them to service levels and more detailed governance models. This will also enable the ability to re-use existing profiles, customizing them for the various service contracts involved.

You recommend all of the extensions be incorporated into the Architecture Content Metamodel. The full Content Metamodel will enable the EA team to capture and categorize all the important additional data needed to support the performance and measurement objectives linked to these artifacts. Once the new repository content has been implemented, on- demand queries can be used to generate a customized governance stakeholder view that isolates

Question 109

You are an Enterprise Architect at a food production and distribution company. The primary goal of the company is to maximize profit while satisfying the needs of consumers for its products. Its customers are demanding food that is produced sustainably, safely, and transparently while reducing environmental impact.

The business is highly mechanized, and this mechanization has caused a decrease in the number of workers needed, together with a focus on agricultural engineering to improve the efficiency of its farms, its processing facilities, and the overall enterprise. As part of this, the company has established an Enterprise Architecture (EA) practice based on the TOGAF standard, using it as the method and guiding framework. The Chief Information Officer (CIO) is the sponsor of EA practice. The introduction of EA has enabled the decision-makers to have valuable insights into the different aspects of the business.

Global warming has caused a lot of poor harvests, and the company is producing fewer crops than before. This combined with an increase in costs for energy, feed, fuel, and fertilizer has led to a significant decrease in profits. The rising costs and reduced profits mean that the company is unable to take as much planned action on climate measures as it would like, such as reducing its carbon footprint. In response to the situation, the Chief Executive Officer (CEO) has decided that big changes are needed that will lead both to improved crop production and profitability. They must look to all aspects of the business. This includes looking at the mix of crops to mitigate for the change in climate.

The company will also cease to process its own crops and will sell off its processing facilities. Thus, the target market will change, and the end-products will be different and more varied. A formal request for architecture change has been approved. At this stage, there is no fixed scope, shared vision, or objectives.

Refer to the scenario:

You have been asked to propose the best approach for architecture development to realize the CEO's change in direction for the company.

Options:

You propose that the priority is to produce a new Request for Architecture Work leading to the development of a new Architecture Vision. The trade-off method should be applied to identify and select an architecture satisfying the stakeholders. For an efficient change, the EA team should be aligned with the organization's planning, budgeting, operational, and change processes.

You propose that this engagement define the baseline Technology Architecture first in order to assess the current infrastructure capacity and capability for the company. Then the focus should be on transition planning and incremental architecture deployment. This will identify requirements to ensure that the projects are sequenced in an optimal fashion so as to realize the change.

You propose that the team uses the architecture definition document and focuses on architecture development starting simultaneously in Phases B, C, and D. This is because the CEO has identified the need to change. This will ensure that the change can be defined in a structured manner and address the requirements needed to realize the change.

You propose that the team focus on architecture definition including the development of business models, with emphasis on defining the change parameters to support this new business strategy that the CEO has identified. Once understood, the team will be in the best position to identify the requirements, drivers, issues, and constraints for the change.

Question 111

Scenario:

Please read this scenario prior to answering the Question

You are serving as the Lead Architect for the enterprise architecture team at the prime contractor for the Dreadnought Unmanned Aircraft System program.

Over the course of this contract, the company has grown rapidly by acquisition and has inherited numerous different procurement processes and related IT systems. The decision has been made to consolidate and reduce redundant procurement processes and systems. The CEO has announced that the company will seek to leverage higher volume discounts and lower related IT support costs by instituting a preferred supplier program.

TOGAF 9 Is used for internal Enterprise Architecture activities, with an iterative approach for executing Architecture Development Method (ADM) projects.

At present, there are no particularly useful architectural assets related to this initiative, so all assets need to be acquired and customized or created from scratch. The company prefers to implement commercial off the shelf package applications with little customization. The CIO, who is the project sponsor, has stated that she is not concerned about preserving existing processes or systems.

The architect-re development project has put in place Its Architecture Capability for this project and has started a number of iteration cycles to develop the Architecture. Some tasks to address concerns related to the Business Architecture have been completed. The next immediate task is to address the Information Systems Architectures.

The Information Systems Architectures must address stakeholder concerns such as:

1. Which procurement-related business processes are supported by zero, one, or many existing applications?

2. What non-procurement applications will need to be integrated with any new procurement applications?

3. What data will need to be shared?
