Exam Terraform Associate topic 1 question 83 discussion

I think it's B for sure

B is the correct answer. Terraform do manage implicit dependencies using the attribute values mentioned in the configuration of the resources.

B, false

https://developer.hashicorp.com/terraform/tutorials/0-13/dependencies?in=terraform%2F0-13 Implicit dependencies are the primary way that Terraform understands the relationships between your resources. Sometimes there are dependencies between resources that are not visible to Terraform, however. The depends_on argument is accepted by any resource or module block and accepts a list of resources to create explicit dependencies for.

B. False. Terraform can manage resource dependencies automatically without explicitly setting them using the depends_on argument.

B is correct. Implicit as well

you have implicit as well, therefore B

Answer is B. Most of the time, Terraform infers dependencies between resources based on the configuration given, so that resources are created and destroyed in the correct order. Occasionally, however, Terraform cannot infer dependencies between different parts of your infrastructure, and you will need to create an explicit dependency with the depends_on argument. https://developer.hashicorp.com/terraform/tutorials/0-13/dependencies?in=terraform%2F0-13

Answer: B "Most of the time, Terraform infers dependencies between resources based on the configuration given, so that resources are created and destroyed in the correct order" -> https://learn.hashicorp.com/tutorials/terraform/dependencies

Terraform automatically infers when one resource depends on another by studying the resource attributes used in interpolation expressions.

A is correct we need pass explicitly depends_on

It is B

B. False implicit = hidden dependencies Trfm can can manage.

B is correct implicit decencies trfm can manage without depends on command, for example in AWS eip resource will be dependent on the Ec2 creation, so trfm will first create the Ec2 and then eip will be allocated/created. and eip creation will be after the creation of Ec2. https://learn.hashicorp.com/tutorials/terraform/dependencies?in=terraform/0-13

I believe A is the correct answer. "Use the depends_on meta-argument to handle hidden resource or module dependencies that Terraform cannot automatically infer. You only need to explicitly specify a dependency when a resource or module relies on another resource's behavior but does not access any of that resource's data in its arguments." https://www.terraform.io/language/meta-arguments/depends_on

Manage explicit dependencies Implicit dependencies are the primary way that Terraform understands the relationships between your resources. Sometimes there are dependencies between resources that are not visible to Terraform, however. The depends_on argument is accepted by any resource or module block and accepts a list of resources to create explicit dependencies for. B

Terraform is smart enough to manage resource dependencies to an extent, without any explicit instructions.
