When does Sentinel enforce policy logic during a Terraform Enterprise run?

• A. Before the plan phase
• B. During the plan phase
• C. Before the apply phase
• D. After the apply phase

Answer: (C)

Policy enforcement gates Terraform runs by evaluating the policy decisions before any changes are applied. In a Terraform Enterprise run, a plan is generated and then Sentinel checks the policy logic against that plan. If all policies pass, the apply proceeds; if any policy fails, the apply is blocked and no changes are made. This means enforcement happens before the apply phase, not before planning, not after applying.
