Please identify the offerings which are unique to Terraform Enterprise, and not available in either Terraform OSS, or Terraform Cloud. Select four.

While Terraform Cloud offers audit trails, Terraform Enterprise, as a self-managed solution, typically provides more granular control and direct access to system-level audit logs, enabling deeper integration with enterprise-specific logging and compliance systems.

Terraform Enterprise can be deployed within an organization's private network infrastructure, allowing the control plane to operate securely without direct exposure to the public internet, a capability not offered by the public SaaS Terraform Cloud service.

VCS Integration is available in both Terraform Cloud and Terraform Enterprise, making it not unique to Enterprise.

Sentinel, HashiCorp's policy-as-code framework, is available in both Terraform Cloud (Business tier) and Terraform Enterprise, thus not being unique to Enterprise.

Terraform Enterprise supports clustered deployments for high availability and scalability, allowing customers to manage the underlying infrastructure for resilience. This differs from Terraform Cloud's managed SaaS architecture and Terraform OSS, which is a single-user command-line tool.
