Which of the following is often a difficult process when working with internationally-based cloud providers?

Litigation hold involves preserving electronically stored information (ESI) in anticipation of legal action, which becomes complex when data is distributed across different international data centers governed by diverse national laws and compliance frameworks. Different countries have distinct rules regarding data access, transfer, and sovereignty, making it difficult to uniformly apply and enforce a legal hold across international boundaries.

Data segregation is a fundamental cloud security control that cloud providers are designed to implement effectively, regardless of their international presence.

Network isolation is a standard security measure within cloud environments, ensuring that different tenants or services are separated, which is a core capability of cloud providers.

Multi-tenancy is a foundational architectural principle of cloud computing, not a difficult process for providers to manage; it's how they achieve economies of scale.
