Exam Terraform Associate topic 1 question 251 discussion

https://developer.hashicorp.com/terraform/language/values/variables#object https://developer.hashicorp.com/terraform/language/values/variables#map here mostly confusion about Object or map . but, Map: variable "image_id" { type = string description = "The id of the machine image (AMI) to use for the server." } eg: terraform apply -var='image_id_map={"us-east-1":"ami-abc123","us-east-2":"ami-def456"}' both key and value pair should be in string format only won't accept numbers where as Object: variable "docker_ports" { type = list(object({ internal = number external = number protocol = string })) default = [ { internal = 8300 external = 8300 protocol = "tcp" } ] } it can be any type var like number, string, bool So here B: Object is the correct option

B. Object The Object type in Terraform allows you to create complex input variables that contain more than one value and can be of different types. variable "server_config" { type = object({ memory = number name = string }) description = "Server configuration values" } In this example, server_config is an object that expects two attributes: memory (a number) and name (a string).

Why not B not C? https://developer.hashicorp.com/terraform/language/expressions/type-constraints map(...): a collection of values where each is identified by a string label. object(...): a collection of named attributes that each have their own type. Values of map is string, values of object is any type.

I choose B
