CISSP Practice Question: What would MOST likely happen if a multinational corporation fails to integrate…

Correct Answer: A. Increased security risks

Explanation (CISSP Manager Logic):

Fragmented IAM systems create visibility gaps and inconsistent policy enforcement across the enterprise. Without a unified identity source, managers cannot ensure the principle of least privilege, leading to orphaned accounts and unauthorized access that compromises the global security posture.

By integrating IAM systems, you:

• Centralize visibility and governance over all user identities.
• Ensure consistent enforcement of security policies and compliance controls.
• Reduce the attack surface by eliminating redundant or unmanaged accounts.

While the other options are relevant, they fall short because:

• B: Fragmented systems decrease productivity by forcing users to manage multiple credentials and workflows.
• C: Inconsistent identity management makes auditing difficult and often leads to significant regulatory non-compliance.
• D: Disparate regional systems complicate administration and increase operational overhead rather than streamlining it.

Think like a manager:

Security requires centralized control to manage risk effectively across a global footprint. Strategic IAM integration ensures that identity—the modern perimeter—is robust, measurable, and consistent.
