Exam Terraform Associate topic 1 question 63 discussion

Answer is correct : True "The expressions in local values are not limited to literal constants; they can also reference other values in the module in order to transform or combine them, including variables, resource attributes, or other local values:" https://www.terraform.io/language/values/locals#declaring-a-local-value

A locals { # Ids for multiple sets of EC2 instances, merged together instance_ids = concat(aws_instance.blue.*.id, aws_instance.green.*.id) } locals { # Common tags to be assigned to all resources common_tags = { Service = local.service_name Owner = local.owner } }

locals { common_tags = { Owner = "team-name" Service = "customer-service" } extra_tags = merge(local.common_tags, { Environment = "production" }) }

The right answer is A as local value can also reference other terraform local value(s)

A is the correct answer

A. True. A Terraform local value can reference other Terraform local values. Local values in Terraform are used to create intermediate values that can be used to simplify complex expressions or avoid duplicating values in the code. They can reference other resources and values within the Terraform configuration.

True; Terraform local values can reference other Terraform local values. This is useful for sharing common values between resources, such as defining a common name or set of tags. When referencing other local values, Terraform will automatically look for the referenced value and substitute it in the configuration. This helps avoid repetition and makes Terraform configurations easier to maintain.
