Which Terraform command checks that your configuration syntax is correct?
A. terraform validate B. terraform init C. terraform show D. terraform fmt
Answer: A
Explanation:
The terraform validate command is used to check that your Terraform configuration files are
syntactically valid and internally consistent. It is a useful command for ensuring your Terraform code
is error-free before applying any changes to your infrastructure.
Question # 2
terraform validate reports syntax check errors for which of the following?
A. Code contains tabs for indentation instead of spaces B. There is a missing value for a variable C. The state file does not match the current infrastructure D. None of the above
Answer: D
Explanation:
The terraform validate command is used to check for syntax errors and internal consistency within
Terraform configurations, such as whether all required arguments are specified. It does not check for
indentation styles, missing variable values (as variables might not be defined at validation time), or
state file consistency with the current infrastructure. Therefore, none of the provided options are
correct in the context of what terraform validate reports.
References = Terraform's official documentation details the purpose and function of the terraform
validate command, specifying that it focuses on syntax and consistency checks within Terraform
configurations themselves, not on external factors like the state file or infrastructure state. Direct
references from the HashiCorp Terraform Associate (003) study materials to this specific detail were
not found in the provided file
Question # 3
Infrastructure as Code (laC) can be stored in a version control system along with application code.
A. True B. False
Answer: A
Explanation:
Infrastructure as Code (IaC) can indeed be stored in a version control system along with application
code. This practice is a fundamental principle of modern infrastructure management, allowing teams
to apply software development practices like versioning, peer review, and CI/CD to infrastructure
management. Storing IaC configurations in version control facilitates collaboration, history tracking,
and change management.
References = While this concept is a foundational aspect of IaC and is widely accepted in the industry,
direct references from the HashiCorp Terraform Associate (003) study materials were not found in
the provided files. However, this practice is encouraged in Terraform's best practices and various
HashiCorp learning resources.
Question # 4
Where in your Terraform configuration do you specify a state backend?
A. The resource block B. The data source block C. The terraform block D. The provider block
Answer: C
Explanation:
In Terraform, the backend configuration, which includes details about where and how state is stored,
is specified within the terraform block of your configuration. This block is the correct place to define
the backend type and its configuration parameters, such as the location of the state file for a local
backend or the bucket details for a remote backend like S3.
References = This practice is outlined in Terraform's core documentation, which provides examples
and guidelines on how to configure various aspects of Terraform's behavior, including state backends
Question # 5
In a Terraform Cloud workspace linked to a version control repository, speculative plan runs startautomatically when you merge or commit changes to version control.
A. True B. False
Answer: B
Explanation:
In Terraform Cloud, speculative plan runs are not automatically started when changes are merged or
committed to the version control repository linked to a workspace. Instead, speculative plans are
typically triggered as part of proposed changes in merge requests or pull requests to give an
indication of what would happen if the changes were applied, without making any real changes to
the infrastructure. Actual plan and apply operations in Terraform Cloud workspaces are usually
triggered by specific events or configurations defined within the Terraform Cloud workspace settings.
References = This behavior is part of how Terraform Cloud integrates with version control systems
and is documented in Terraform Cloud's usage guidelines and best practices, especially in the context
of VCS-driven workflows.
Question # 6
Which of the following arguments are required when declaring a Terraform output?
A. value B. description C. default D. sensitive
Answer: A
Explanation:
When declaring a Terraform output, the value argument is required. Outputs are a way to extract
information from Terraform-managed infrastructure, and the value argument specifies what data will
be outputted. While other arguments like description and sensitive can provide additional context or
security around the output, value is the only mandatory argument needed to define an output.
References = The requirement of the value argument for outputs is specified in Terraform's official
documentation, which provides guidelines on defining and using outputs in Terraform configurations
Question # 7
You're writing a Terraform configuration that needs to read input from a local file called id_rsa.pub .Which built-in Terraform function can you use to import the file's contents as a string?
A. file("id_rsa.pub") B. templaTefil("id_rsa.pub") C. filebase64("id_rsa.pub") D. fileset<"id_rsa.pub")
Answer: A
Explanation:
To import the contents of a local file as a string in Terraform, you can use the built-in file function. By
specifying file("id_rsa.pub"), Terraform reads the contents of the id_rsa.pub file and uses it as a string
within your Terraform configuration. This function is particularly useful for scenarios where you need
to include file data directly into your configuration, such as including an SSH public key for
provisioning cloud instances.
References = This information is a standard part of Terraform's functionality with built-in functions,
as outlined in Terraform's official documentation and commonly used in various Terraform
Question # 8
While attempting to deploy resources into your cloud provider using Terraform, you begin to seesome odd behavior and experience slow responses. In order to troubleshoot you decide to turn onTerraform debugging. Which environment variables must be configured to make Terraform's loggingmore verbose?
A. TF_LOG_PAIH B. TF_LOG C. TF_VAR_log_path D. TF_VAR_log_leve
Answer: B
Explanation:
To make Terraform's logging more verbose for troubleshooting purposes, you must configure the
TF_LOG environment variable. This variable controls the level of logging and can be set to TRACE,
DEBUG, INFO, WARN, or ERROR, with TRACE providing the most verbose output.
References = Detailed debugging instructions and the use of environment variables like TF_LOG for
increasing verbosity are part of Terraform's standard debugging practices
Question # 9
Before you can use a remote backend, you must first execute terra-form init.
A. True B. False
Answer: A
Explanation:
Before using a remote backend in Terraform, it is mandatory to run terraform init. This command
initializes a Terraform working directory, which includes configuring the backend. If a remote
backend is specified, terraform init will set up the working directory to use it, including copying any
existing state to the remote backend if necessary.
References = This principle is a fundamental part of working with Terraform and its backends, as
outlined in general Terraform documentation and best practices. The specific HashiCorp Terraform
Associate (003) study materials in the provided files did not include direct references to this
information
Question # 10
Why would you use the -replace flag for terraform apply?
A. You want Terraform to ignore a resource on the next apply B. You want Terraform to destroy all the infrastructure in your workspace C. You want to force Terraform to destroy a resource on the next apply D. You want to force Terraform to destroy and recreate a resource on the next apply
Answer: D
Explanation:
The -replace flag is used with the terraform apply command when there is a need to explicitly force
Terraform to destroy and then recreate a specific resource during the next apply. This can be
necessary in situations where a simple update is insufficient or when a resource must be reprovisioned
to pick up certain changes.
Question # 11
terraform plan updates your state file.
A. True B. False
Answer: B
Explanation:
The terraform plan command does not update the state file. Instead, it reads the current state and
the configuration files to determine what changes would be made to bring the real-world
infrastructure into the desired state defined in the configuration. The plan operation is a read-only
operation and does not modify the state or the infrastructure. It is the terraform apply command that
actually applies changes and updates the state file.
References = Terraform's official guidelines and documentation clarify the purpose of the terraform
plan command, highlighting its role in preparing and showing an execution plan without making any
changes to the actual state or infrastructure
Question # 12
Define the purpose of state in Terraform.
A. State maps real world resources to your configuration and keeps track of metadata B. State lets you enforce resource configurations that relate to compliance policies C. State stores variables and lets you quickly reuse existing code D. State codifies the dependencies of related resources
Answer: A
Explanation:
The purpose of state in Terraform is to keep track of the real-world resources managed by Terraform,
mapping them to the configuration. The state file contains metadata about these resources, such as
resource IDs and other important attributes, which Terraform uses to plan and manage infrastructure
changes. The state enables Terraform to know what resources are managed by which configurations
and helps in maintaining the desired state of the infrastructure.
References = This role of state in Terraform is outlined in Terraform's official documentation,
emphasizing its function in mapping configuration to real-world resources and storing vital metadata
Question # 13
Which of these actions will prevent two Terraform runs from changing the same state file at the sametime?
A. Refresh the state after running Terraform B. Delete the state before running Terraform C. Configure state locking for your state backend D. Run Terraform with parallelism set to 1
Answer: B
Explanation:
To prevent two Terraform runs from changing the same state file simultaneously, state locking is
used. State locking ensures that when one Terraform operation is running, others will be blocked
from making changes to the same state, thus preventing conflicts and data corruption. This is
achieved by configuring the state backend to support locking, which will lock the state for all
operations that could write to the state.
References = This information is supported by Terraform's official documentation, which explains the
importance of state locking and how it can be configured for different backends to prevent
concurrent state modifications
Question # 14
Which type of block fetches or computes information for use elsewhere in a Terraform configuration?
A. data B. local C. resource D. provider
Answer: A
Explanation:
In Terraform, a data block is used to fetch or compute information from external sources for use
elsewhere in the Terraform configuration. Unlike resource blocks that manage infrastructure, data
blocks gather information without directly managing any resources. This can include querying for
data from cloud providers, external APIs, or other Terraform states.
References = This definition and usage of data blocks are covered in Terraform's official
documentation, highlighting their role in fetching external information to inform Terraform
configurations
Question # 15
Changing the Terraform backend from the default "local" backend to a different one after performingyour first terrafom apply is:
A. Optional B. Impossible C. Mandatory D. Discouraged
Answer: D
Explanation:
Changing the Terraform backend after performing the initial terraform apply is technically possible
but strongly discouraged. This is because changing backends can lead to complexities in state
management, requiring manual intervention such as state migration to ensure consistency.
Terraform's documentation and best practices advise planning the backend configuration carefully
before applying Terraform configurations to avoid such changes.
References = This guidance is consistent with Terraform's official documentation, which recommends
careful consideration and planning of backend configurations to avoid the need for changes.
Question # 16
Which of the following is not a valid source path for specifying a module?
A. source - "github.com/hashicorp/examplePref-ul.0.8M B. source = "./module?version=vl.6.0" C. source - "hashicorp/consul/aws" D. source - "./module"
Answer: B
Explanation:
Terraform modules are referenced by specifying a source location. This location can be a URL or a file
path. However, specifying query parameters such as ?version=vl.6.0 directly within the source path is
not a valid or supported method for specifying a module version in Terraform. Instead, version
constraints are specified using the version argument within the module block, not as part of the
source string.
References = This clarification is based on Terraform's official documentation regarding module
usage, which outlines the correct methods for specifying module sources and versions
Question # 17
What are some benefits of using Sentinel with Terraform Cloud/Terraform Cloud? Choose threecorrect answers.
A. You can restrict specific resource configurations, such as disallowing the use of CIDR=0.0.0.0/0. B. You can check out and check in cloud access keys C. Sentinel Policies can be written in HashiCorp Configuration Language (HCL) D. Policy-as-code can enforce security best practices E. You can enforce a list of approved AWS AMIs
Answer: A,D,E
Explanation:
Sentinel is a policy-as-code framework that allows you to define and enforce rules on your Terraform
configurations, states, and plans1. Some of the benefits of using Sentinel with Terraform
Cloud/Terraform Enterprise are:
You can restrict specific resource configurations, such as disallowing the use of CIDR=0.0.0.0/0,
which would open up your network to the entire internet. This can help you prevent
misconfigurations or security vulnerabilities in your infrastructure2.
Policy-as-code can enforce security best practices, such as requiring encryption, authentication, or
compliance standards. This can help you protect your data and meet regulatory requirements3.
You can enforce a list of approved AWS AMIs, which are pre-configured images that contain the
operating system and software you need to run your applications. This can help you ensure
consistency, reliability, and performance across your infrastructure4.

Question # 18
Which of the following are advantages of using infrastructure as code (laC) instead of provisioningwith a graphical user interface (GUI)? Choose two correct answers.
A. Prevents manual modifications to your resources B. Lets you version, reuse, and share infrastructure configuration C. Secures your credentials D. Provisions the same resources at a lower cost E. Reduces risk of operator error
Answer: B,E
Explanation:
Infrastructure as code (IaC) is a way of managing and provisioning cloud infrastructure using
programming techniques instead of manual processes1. IaC has many advantages over using a
graphical user interface (GUI) for provisioning infrastructure, such as:
Versioning: IaC allows you to store your infrastructure configuration in a version control system,
such as Git, and track changes over time. This enables you to roll back to previous versions, compare
differences, and collaborate with other developers2.
Reusability: IaC allows you to create reusable modules and templates that can be applied to
different environments, such as development, testing, and production. This reduces duplication,
improves consistency, and speeds up deployment3.
Sharing: IaC allows you to share your infrastructure configuration with other developers, teams, or
organizations, and leverage existing code from open source repositories or registries. This fosters
best practices, innovation, and standardization4.
Risk reduction: IaC reduces the risk of human error, configuration drift, and security breaches that
can occur when provisioning infrastructure manually or using a GUI. IaC also enables you to perform
automated testing, validation, and compliance checks on your infrastructure before deploying it5.

Question # 19
Which of the following is not true of Terraform providers?
A. An individual person can write a Terraform Provider B. A community of users can maintain a provider C. HashiCorp maintains some providers D. Cloud providers and infrastructure vendors can write, maintain, or collaborate on Terraform E. providers F. None of the above
Answer: F
Explanation:
All of the statements are true of Terraform providers. Terraform providers are plugins that enable
Terraform to interact with various APIs and services1. Anyone can write a Terraform provider, either
as an individual or as part of a community2. HashiCorp maintains some providers, such as the AWS,
Azure, and Google Cloud providers3. Cloud providers and infrastructure vendors can also write,
maintain, or collaborate on Terraform providers, such as the VMware, Oracle, and Alibaba Cloud
providers.

Question # 20
The Terraform binary version and provider versions must match each other in a single configuration.
A. True B. False
Answer: B
Explanation:
The Terraform binary version and provider versions do not have to match each other in a single
configuration. Terraform allows you to specify provider version constraints in the configurations
terraform block, which can be different from the Terraform binary version1. Terraform will use the
newest version of the provider that meets the configurations version constraints2. You can also use
the dependency lock file to ensure Terraform is using the correct provider version3.

2: Multiple provider versions with Terraform - Stack Overflow
Which of these is true about Terraform's plugin-based architecture?
A. Terraform can only source providers from the internet B. Every provider in a configuration has its own state file for its resources C. You can create a provider for your API if none exists D. All providers are part of the Terraform core binary
Answer: C
Explanation:
Terraform is built on a plugin-based architecture, enabling developers to extend Terraform by writing
new plugins or compiling modified versions of existing plugins1. Terraform plugins are executable
binaries written in Go that expose an implementation for a specific service, such as a cloud resource,
SaaS platform, or API2. If there is no existing provider for your API, you can create one using the
Terraform Plugin SDK3 or the Terraform Plugin Framework4.

Question # 22
Which is the best way to specify a tag of v1.0.0 when referencing a module stored in Git (for example. Git::https://example.com/vpc.git)?
A. Append pref=v1.0.0 argument to the source path B. Add version = œ1.0.0 parameter to module block C. Nothing modules stored on GitHub always default to version 1.0.0
Answer: A
Explanation:
The best way to specify a tag of v1.0.0 when referencing a module stored in Git is to append ?ref=v1.0.0 argument to the source path. This tells Terraform to use a specific Git reference, such as a branch, tag, or commit, when fetching the module source code. For example, source = "git::https://example.com/vpc.git?ref=v1.0.0". This ensures that the module version is consistent and reproducible across different environments. Reference = [Module Sources], [Module Versions]
Question # 23
Terraform configuration can only import modules from the public registry.
A. True B. False
Answer: B
Explanation:
Terraform configuration can import modules from various sources, not only from the public registry.
Modules can be sourced from local file paths, Git repositories, HTTP URLs, Mercurial repositories, S3 buckets, and GCS buckets. Terraform supports a number of common conventions and syntaxes for specifying module sources, as documented in the [Module Sources] page. Reference = [Module Sources]
Question # 24
Which configuration consistency errors does terraform validate report?
A. Terraform module isn't the latest version B. Differences between local and remote state C. Declaring a resource identifier more than once D. A mix of spaces and tabs in configuration files
Answer: C
Explanation:
Terraform validate reports configuration consistency errors, such as declaring a resource identifier more than once. This means that the same resource type and name combination is used for multiple resource blocks, which is not allowed in Terraform. For example, resource "aws_instance" "example" {...} cannot be used more than once in the same configuration. Terraform validate does not report errors related to module versions, state differences, or formatting issues, as these are not relevant for checking the configuration syntax and structure. Reference = [Validate Configuration], [Resource Syntax]
Question # 25
When should you use the force-unlock command?
A. You have a high priority change B. Automatic unlocking failed C. apply failed due to a state lock D. You see a status message that you cannot acquire the lock
Answer: B
Explanation:
You should use the force-unlock command when automatic unlocking failed. Terraform will lock your
state for all operations that could write state, such as plan, apply, or destroy. This prevents others
from acquiring the lock and potentially corrupting your state. State locking happens automatically on
all operations that could write state and you wont see any message that it is happening. If state
locking fails, Terraform will not continue. You can disable state locking for most commands with the -
lock flag but it is not recommended. If acquiring the lock is taking longer than expected, Terraform
will output a status message. If Terraform doesnt output a message, state locking is still occurring if
your backend supports it. Terraform has a force-unlock command to manually unlock the state if
unlocking failed. Be very careful with this command. If you unlock the state when someone else is
holding the lock it could cause multiple writers. Force unlock should only be used to unlock your own
lock in the situation where automatic unlocking failed. To protect you, the force-unlock command
requires a unique lock ID. Terraform will output this lock ID if unlocking fails. This lock ID acts as a
nonce, ensuring that locks and unlocks target the correct lock. The other situations are not valid
reasons to use the force-unlock command. You should not use the force-unlock command if you have
a high priority change, if apply failed due to a state lock, or if you see a status message that you
cannot acquire the lock. These situations indicate that someone else is holding the lock and you
should wait for them to finish their operation or contact them to resolve the issue. Using the forceunlock
command in these cases could result in data loss or inconsistency. Reference = [State Locking],
[Command: force-unlock]
