In a community cloud, which component might be the most difficult for the member organizations to manage?

• A. Network Management
• B. Data Encryption
• C. Resource Provisioning
• D. Access Control for Users

Answer: (D)

Coordinating who can access what across multiple member organizations introduces the most complexity. In a community cloud, user access control must support federated authentication and cross-tenant authorization, align different organizations’ roles and policies, and maintain strict separation of data and resources. This means managing diverse identities (employees, contractors, partners), handling guest access, promptly revoking permissions when roles change, and producing audit trails that satisfy all parties. While network management, encryption policies, and automated resource provisioning can be standardized and automated across the shared environment, access control for users inherently requires reconciling multiple governance models and compliance requirements, making it the most challenging aspect to manage.
