ASecurity and Privacy, and Governance
BManagement, and Data Provenance
CGovernance, and Resource Negotiation
DSecurity and Privacy, and Management
Answer & Solution
Correct answer: D. Security and Privacy, and Management
1. The volume names them in a short list of their own: "The two fabrics, which are discussed separately in Sections 3 and 4, are: Security and Privacy Fabric; Management Fabric."
2. So there are exactly two, and they are Security and Privacy, and Management.
3. They are separated from the five components because they cannot be confined to one place.
Volume 1 defines a fabric as "the presence of activities and components throughout a computing system", and the volume describes these two as "interwoven in the five components".
4. Governance is the most tempting wrong answer because it is genuinely important here, but the volume places it inside the System Orchestrator's responsibilities rather than treating it as a fabric.
5. Data provenance and resource negotiation are both real terms in this framework, describing where data came from and the built-in management capabilities of a platform, but neither is one of the two fabrics.
