Question

A SysOps administrator manages two separate CloudFormation stacks. A networking stack creates a VPC and subnets and exposes their IDs using the Export field in its Outputs section. An application stack references these values with Fn::ImportValue. When the administrator attempts to delete the networking stack, the deletion fails. What is the cause, and how should the administrator resolve it?

Accepted Answer

The networking stack cannot be deleted while another stack imports its exported values; the application stack must be deleted or updated to remove the imports first.

Answer

The exported values exceeded the maximum size limit; the administrator must split the exports across multiple stacks before deletion.

Answer

Drift was detected on the networking stack; the administrator must run drift detection and remediate before the stack can be deleted.

Answer

The stack has a stack policy that denies deletion; the administrator must update the stack policy to allow the Delete action.
