Question

How would you reference the Volume IDs associated with the ebs_block_device blocks in this configuration?

Options

Aaws_instance.example.ebs_block_device.[*].volume_id
Baws_instance.example.ebs_block_device.volume_id
Caws_instance.example.ebs_block_device[sda2,sda3].volume_id
Daws_instance.example.ebs_block_device.*.volume_id

Explanation

{"question_number": 7, "explanation": "Because ebs_block_device is a block that can appear multiple times in a single aws_instance resource, it forms a set of objects. To retrieve an attribute across all instances of a repeated block, you use a splat expression with [*]: aws_instance.example.ebs_block_device.[*].volume_id. This returns a list of all volume IDs from all ebs_block_device blocks. The legacy splat syntax .* also works but [*] is the modern, preferred form. Options B and C are syntactically invalid for this use case. Answer A is correct.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
