Question 36

ABC Enterprise has recently tied up with multiple small organizations for exchanging database information. Due to this, the firewall rules are increasing and are more than 100 rules. This is leading firewall configuration file that is difficult to manage. What is the way this type of configuration can be managed easily?

A.Terraform Backends
B.Dynamic Blocks
C.Terraform Expression
D.Terraform Functions

Question 37

Which of the following is the correct way to pass the value in the variable num_servers into a module with the input servers?

A.servers = var(num_servers)
B.servers = num_servers
C.servers = var.num_servers
D.servers = variable.num_servers

Question 38

Given the Terraform configuration below, in which order will the resources be created?
1. resource "aws_instance" "web_server"
2. {
3. ami = "ami-b374d5a5"
4. instance_type = "t2.micro"
5. }
6. resource "aws_eip" "web_server_ip"
7. {
8. vpc = true instance = aws_instance.web_server.id
9. }

A.aws_eip will be created first
aws_instance will be created second
B.aws_eip will be created first
aws_instance will be created second
C.Resources will be created simultaneously
D.aws_instance will be created first
aws_eip will be created second

Correct Answer: D

Explanation
Implicit and Explicit Dependencies
By studying the resource attributes used in interpolation expressions, Terraform can automatically infer when one resource depends on another. In the example above, the reference to aws_instance.web_server.id creates an implicit dependency on the aws_instance named web_server.
Terraform uses this dependency information to determine the correct order in which to create the different resources.
# Example of Implicit Dependency
resource "aws_instance" "web_server" {
ami = "ami-b374d5a5"
instance_type = "t2.micro"
}
resource "aws_eip" "web_server_ip" {
vpc = true
instance = aws_instance.web_server.id
}
In the example above, Terraform knows that the aws_instance must be created before the aws_eip.
Implicit dependencies via interpolation expressions are the primary way to inform Terraform about these relationships, and should be used whenever possible.
Sometimes there are dependencies between resources that are not visible to Terraform. The depends_on argument is accepted by any resource and accepts a list of resources to create explicit dependencies for.
For example, perhaps an application we will run on our EC2 instance expects to use a specific Amazon S3 bucket, but that dependency is configured inside the application code and thus not visible to Terraform. In that case, we can use depends_on to explicitly declare the dependency:
# Example of Explicit Dependency
# New resource for the S3 bucket our application will use.
resource "aws_s3_bucket" "example" {
bucket = "terraform-getting-started-guide"
acl = "private"
}
# Change the aws_instance we declared earlier to now include "depends_on" resource "aws_instance" "example" { ami = "ami-2757f631" instance_type = "t2.micro"
# Tells Terraform that this EC2 instance must be created only after the
# S3 bucket has been created.
depends_on = [aws_s3_bucket.example]
}

Question 39

Refer to the below code where developer is outputting the value of the database password but has used sensitive parameter to hide the output value in the CLI.
output "db_password" { value = aws_db_instance.db.password description = "The password for logging in to the database." sensitive = true} Since sensitive is set to true, the value associated with db password will not be present in state file as plain-text?

A.False
B.True

Question 40

Refer to the following terraform variable definition
variable "track_tag" { type = list default = ["data_ec2","integration_ec2","digital_ec2"]} track_tag = { Name = element(var.track_tag,count.index)} If count.index is set to 2, which of the following values will be assigned to the name attribute of track_tag variable?

A.digital_ec2
B.data_ec2
C.track_tag
D.integration_ec2
