Which of the following is MOST important to consider when planning to implement a cloud-based application for sharing documents with internal and external parties?

The cloud implementation model (e.g., public, private, hybrid) is a foundational decision, but it's a technical implementation detail that supports, rather than dictates, the specific access control needs for external sharing.

User experience is important for adoption and efficiency, but it is secondary to the fundamental security and compliance implications of external data sharing.

Information ownership is a key governance aspect, but the *application* of that ownership to control *third-party access* is the critical operational consideration for secure external sharing.

When sharing documents with internal and *external* parties, managing third-party access rights is MOST important because it directly controls who can view, modify, or share sensitive information outside the organizational perimeter. Properly defining and enforcing these rights is crucial for data security, compliance, and preventing unauthorized disclosure or data breaches, especially when collaborating with external entities.
