Exam OG0-092 topic 1 question 72 discussion

You are working as a consultant to the Chief Architect at an intelligent 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 remove 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-preformcane, and secure communications are essential to be preserving national security, the Executive Director has placed stringent requirements for 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 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 conduct 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 implemenations 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, Version 9.2, which of the following is the best answer?
