Isaca AAIR - ISACA Advanced in AI Risk

A RACI (Responsible, Accountable, Consulted, Informed) matrix is a governance tool that explicitly maps roles and decision authority across project activities. For AI systems, RACI frameworks ensure that accountability for decisions, outputs, and risk management is clearly defined and documented.

Why D is Correct: The ISACA AAIR curriculum identifies the RACI matrix as a foundational accountability instrument. Its primary benefit is establishing unambiguous responsibility and decision authority, which is essential for AI governance where multiple stakeholders—technical teams, business owners, risk practitioners, compliance officers—must work together with clear lanes of authority. This clarity prevents accountability gaps and ensures risk management actions are owned.

Why A is Wrong: Facilitating collaboration is a secondary benefit. While RACI does support cross-functional coordination, collaboration enablement is not its defining purpose. Collaboration can occur without a RACI through other mechanisms.

Why B is Wrong: Consolidating governance authority in senior leadership describes centralization, which is not the purpose of RACI. In fact, RACI typically distributes responsibility across multiple levels rather than consolidating it.

Why C is Wrong: Strengthening technical development governance is an application of the RACI, not its primary benefit. The RACI benefit is accountability clarity, which then supports technical and architectural governance.

Autonomous agents creating HR system identities that exist outside the organization's federated identity management system create invisible, unmanaged access pathways. These shadow identities bypass the centralized access governance controls designed to enforce least privilege, monitor access activity, and enable rapid deprovisioning.

Why D is Correct: According to ISACA AAIR identity and access management guidance for autonomous AI systems, identities not incorporated into the federated system pose the greatest risk because they are invisible to access governance processes. Federated identity management provides centralized provisioning, deprovisioning, monitoring, and policy enforcement. Autonomous identities outside this system can accumulate inappropriate access rights, persist after their legitimate purpose expires, and be used for unauthorized actions—entirely outside the organization's visibility.

Why A is Wrong: Breach identification delays are a consequence of the visibility gap created by ungoverned identities, not the root risk. The primary risk is the existence of invisible access pathways; delayed detection is a downstream effect.

Why B is Wrong: Ineffective credential management is a specific implementation problem with known credentials. The greater risk here is identities that the credential management system doesn't know about at all—complete invisibility is worse than imperfect management.

Why C is Wrong: Increased staffing for human validation is an operational resource impact. While relevant to managing autonomous agent oversight, staffing requirements are a manageable operational concern, not the greatest governance risk from ungoverned identities.
