OG0-092: TOGAF 9 Part 2 Exam

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

The agency has an established Enterprise Architecture (EA) capability based on the TOGAF standard. The agency's Executive Director sponsors the EA capability.

Because reliable, high-performance, and secure communications are essential to preserving national security, the Executive Director has imposed stringent requirements on the architecture of the upgraded systems. It must be able to provide assurance of the upgraded systems. It must be able to provide assurance and verification of specific performance measures for the key services most crucial to 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 perform a review of the EA. The review's scope is to evaluate the processes, content, and governance of the EA capability to ensure that the upgraded system can achieve the required higher target performance and service levels.

The Chief Architect has observed that the core EA artifacts currently in use cannot describe these new capabilities. The artifacts lack explicit provisions to define the in-depth measurement requirements for the specific system services. She has learned that certain services in the current system have service-measurement implementations matching some new requirements, but these are used in only a few areas.

Recent EA work at another national agency has produced generalized high-performance communication-system models to realize comparable requirements in a critical defense system involving secure communications. These models may be useful for the upgrade program.

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

You have been asked to recommend tailoring of the Architecture Content Metamodel to accommodate the upgraded-system requirements.

Based on the TOGAF Standard, Version 9.2, which of the following is the best answer?
