Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Define multiple resources and use 'depends_on' to link them.
Why it's wrong here
'depends_on' defines order, not conditional existence.
- ✓
Use the 'count' meta-argument with a ternary expression.
Why this is correct
Setting 'count = var.enabled ? 1 : 0' is the standard pattern for conditional resource creation.
- ✗
Use an 'if' block around the resource definition.
Why it's wrong here
HCL does not support 'if' blocks for resource definitions.
- ✗
Use the 'module' meta-argument inside the resource.
Why it's wrong here
This is not a valid Terraform construct.
