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

A litigation hold requires an organization to preserve all relevant data in a legally defensible manner once litigation is anticipated. When data is stored with international cloud providers, conflicting national laws, data sovereignty regulations, and provider terms may prevent timely retrieval, suspension of deletion policies, or enforcement of preservation orders - making litigation hold one of the most legally and logistically complex cloud governance challenges across borders.

Data segregation is a technical control that isolates one tenant's data from another and is managed at the provider infrastructure level without significant international legal complexity.

Network isolation is a standard cloud networking feature implemented through VLANs, VPCs, or security groups and is not uniquely difficult in an international context.

Multi-tenancy is a fundamental cloud architecture design principle and is not a process that organizations must carry out - it is an inherent provider-side implementation detail.
