Which statements are true about network security? (Choose two)

Access can be restricted between tenancies and within the tenancy itself is a foundational principle of network security in cloud environments. By setting up proper permissions and policies, organizations can ensure that resources are accessed only by authorized entities, effectively protecting sensitive data and maintaining compliance with security protocols. This capability allows for the segmentation of resources and traffic flow, which is vital for maintaining a secure cloud infrastructure.

The other correct statement, while not chosen, pertains to the use of permissions to isolate networking between compartments and Virtual Cloud Networks (VCNs). This concept highlights that network security is not just about external threats, but also about the internal organization of resources. By leveraging permissions, organizations can create layers of security that prevent unauthorized access and ensure that different workloads or services within the cloud can operate independently and securely.

Understanding these principles allows organizations to design their network architectures with enhanced security and operational efficiency, underscoring the importance of both external and internal access controls in a cloud environment.
