NEW QUESTION # 16
When writing Terraform code, HashiCorp recommends that you use how many spaces between each nesting
level?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
Explanation
The Terraform parser allows you some flexibility in how you lay out the elements in your configuration files,
but the Terraform language also has some idiomatic style conventions which we recommend users always
follow for consistency between files and modules written by different teams. Automatic source code
formatting tools may apply these conventions automatically.
Indent two spaces for each nesting level.
When multiple arguments with single-line values appear on consecutive lines at the same nesting level, align
their equals signs:
ami = "abc123"
instance_type = "t2.micro"
When both arguments and blocks appear together inside a block body, place all of the arguments together at
the top and then place nested blocks below them. Use one blank line to separate the arguments from the
blocks.
Use empty lines to separate logical groups of arguments within a block.
For blocks that contain both arguments and "meta-arguments" (as defined by the Terraform language
semantics), list meta-arguments first and separate them from other arguments with one blank line. Place
meta-argument blocks last and separate them from other blocks with one blank line.
resource "aws_instance" "example" {
count = 2 # meta-argument first
ami = "abc123"
instance_type = "t2.micro"
network_interface {
# ...
}
lifecycle { # meta-argument block last
create_before_destroy = true
}
}
Top-level blocks should always be separated from one another by one blank line. Nested blocks should also be
separated by blank lines, except when grouping together related blocks of the same type (like multiple
provisioner blocks in a resource).
Avoid separating multiple blocks of the same type with other blocks of a different type, unless the block types
are defined by semantics to form a family. (For example: root_block_device, ebs_block_device and
ephemeral_block_device on aws_instance form a family of block types describing AWS block devices, and
can therefore be grouped together and mixed.)

NEW QUESTION # 18
How does the Terraform cloud integration differ from other state backends such as S3, Consul,etc?
- A. It is only arable lo paying customers
- B. It can execute Terraform runs on dedicated infrastructure in Terraform Cloud
- C. It doesn't show the output of a terraform apply locally
- D. All of the above
Answer: B
Explanation:
This is how the Terraform Cloud integration differs from other state backends such as S3, Consul, etc., as it allows you to perform remote operations on Terraform Cloud's servers instead of your local machine. The other options are either incorrect or irrelevant.
NEW QUESTION # 19
From the answers below, select the advantages of using Infrastructure as Code.
- A. Provide a codified workflow to develop customer-facing applications.
- B. Easily change and update existing infrastructure.
- C. Easily integrate with application workflows (GitLab Actions, Azure DevOps, CI/CD tools).
- D. Safely test modifications using a "dry run" before applying any actual changes.
- E. Provide reusable modules for easy sharing and collaboration.
Answer: B,C,D,E
Explanation:
Explanation
Infrastructure as Code is not used to develop applications, but it can be used to help deploy or provision those
applications to a public cloud provider or on-premises infrastructure.
All of the others are benefits to using Infrastructure as Code over the traditional way of managing
infrastructure, regardless if it's public cloud or on-premises.
NEW QUESTION # 20

NEW QUESTION # 21
You have multiple developers working on a terraform project (using terraform OSS), and have saved the terraform state in a remote S3 bucket . However ,team is intermittently experiencing inconsistencies in the provisioned infrastructure / failure in the code . You have traced this problem to simultaneous/concurrent runs of terraform apply command for 2/more developers . What can you do to fix this problem?
- A. Stop using remote state , and store the developer tfstate in their own machine . Once a day , all developers should sit together and merge the state files manually , to avoid any inconsistencies.
- B. Use terraform workspaces feature, this will fix this problem by default , as every developer will have their own state file , and terraform will merge them on server side on its own.
- C. Enable terraform state locking for the S3 backend using DynamoDB table. This prevents others from acquiring the lock and potentially corrupting your state.
- D. Structure your team in such a way that only one individual will run terraform apply , everyone will just make changes and share with him. Then there will be no chance of any inconsistencies.
Answer: C
Explanation:
Explanation
S3 backend support state locking using DynamoDB.

NEW QUESTION # 22
Given the below resource configuration -
resource "aws_instance" "web" { # ... count = 4 }
What does the terraform resource address aws_instance.web refer to?
- A. The above will result in a syntax error , as it is not syntactically correct . Resources defined using count , can only be referenced using indexes.
- B. It refers to the first web EC2 instance out of the 4 ,as by default , if no index is provided , the first / 0th index is used.
- C. It refers to the last web EC2 instance , as by default , if no index is provided , the last / N-1 index is used.
- D. It refers to all 4 web instances , together , for further individual segregation , indexing is required , with a 0 based index.
Answer: D
Explanation:
A Resource Address is a string that references a specific resource in a larger infrastructure. An address is made up of two parts:
[module path][resource spec]
Module path:
A module path addresses a module within the tree of modules. It takes the form:
module.A.module.B.module.C...
Multiple modules in a path indicate nesting. If a module path is specified without a resource spec, the address applies to every resource within the module. If the module path is omitted, this addresses the root module.
Given a Terraform config that includes:
resource "aws_instance" "web" {
# ...
count = 4
}
An address like this:
aws_instance.web[3]
Refers to only the last instance in the config, and an address like this:
aws_instance.web
Refers to all four "web" instances.

NEW QUESTION # 25
If a Terraform creation-time provisioner fails, what will occur by default?
- A. Nothing, provisioners will not show errors in the command line
- B. The resource will not be affected, but the provisioner will need to be applied again
- C. The resource will be destroyed
- D. The resource will be marked as "tainted"
Answer: D
NEW QUESTION # 26
Which Terraform command will force a marked resource to be destroyed and recreated on the next apply?
- A. terraform destroy
- B. terraform taint
- C. terraform fmt
- D. terraform refresh
Answer: B
Explanation:
Explanation
The terraform taint command manually marks a Terraform-managed resource as tainted, forcing it to be destroyed and recreated on the next apply.
This command will not modify infrastructure, but does modify the state file in order to mark a resource as tainted. Once a resource is marked as tainted, the next plan will show that the resource will be destroyed and recreated and the next apply will implement this change.
Forcing the recreation of a resource is useful when you want a certain side effect of recreation that is not visible in the attributes of a resource. For example: re-running provisioners will cause the node to be different or rebooting the machine from a base image will cause new startup scripts to run.
Note that tainting a resource for recreation may affect resources that depend on the newly tainted resource. For example, a DNS resource that uses the IP address of a server may need to be modified to reflect the potentially new IP address of a tainted server. The plan command will show this if this is the case.
