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

1. A. aws_instance.example.ebs_block_device[sda2,sda3).volume_id
2. B. aws_lnstance.example.ebs_block_device.[*].volume_id
3. C. aws_lnstance.example.ebs_block_device.volume_ids
4. D. aws_instance.example-ebs_block_device.*.volume_id

Correct Answer: D
This is the correct way to reference the volume IDs associated with the ebs_block_device blocks in this configuration, using the splat expression syntax. The other options are either invalid or incomplete.

Which Terraform collection type should you use to store key/value pairs?

1. A. Set
2. B. Map
3. C. Tuple
4. D. list

Correct Answer: B
The Terraform collection type that should be used to store key/value pairs is map. A map is a collection of values that are accessed by arbitrary labels, called keys.
The keys and values can be of any type, but the keys must be unique within a map. For example, var = { key1 = "value1", key2 = "value2" } is a map with two key/value pairs. Maps are useful for grouping related values together, such as configuration options or
metadata. References = [Collection Types], [Map Type Constraints]

You can configure Terraform to log to a file using the TF_LOG environment variable.

1. A. True
2. B. False

Correct Answer: A
You can configure Terraform to log to a file using the TF_LOG environment variable. This variable can be set to one of the log levels: TRACE, DEBUG, INFO, WARN or ERROR. You can also use the TF_LOG_PATH environment variable to specify a custom log file location. References = : Debugging Terraform

You want to define multiple data disks as nested blocks inside the resource block for a virtual machine. What Terraform feature would help you define the blocks using the values in a variable?

1. A. Local values
2. B. Count arguments
3. C. Collection functions
4. D. Dynamic blocks

Correct Answer: D
Dynamic blocks in Terraform allow you to define multiple nested blocks within a resource based on the values of a variable. This feature is particularly useful for scenarios where the number of nested blocks is not fixed and can change based on variable input.
