Use Terraform outside the core workflow

A team needs to share a Terraform module across multiple projects within their organization. What is the best practice?

What is the purpose of the 'terraform validate' command?

Refer to the exhibit. An operator runs terraform plan and gets the following output. They have not modified the Terraform configuration since the last successful apply. What is the most likely cause of the planned changes?

Which THREE of the following are capabilities of Terraform Cloud's Sentinel policy framework? (Choose three.)

Which THREE of the following are necessary steps to configure OIDC (OpenID Connect) for authenticating Terraform in a CI/CD pipeline?

A company uses Terraform to manage multi-cloud infrastructure. They have separate Terraform configurations for AWS and Azure, each with its own state file. They want to share a common set of networking variables (e.g., allowed IP ranges) between these configurations without duplicating data. Which approach best achieves this?

Which THREE of the following are best practices for Terraform state management?

Your team stores Terraform state in an AWS S3 bucket and uses DynamoDB for state locking. A junior engineer runs `terraform apply` locally while a CI pipeline is also running `terraform apply` against the same state. The apply succeeds in both cases, but the resulting infrastructure is inconsistent and resources are missing from state. What is the most likely cause?

A company uses Terraform Cloud and wants to enforce policy checks before any apply. They have a set of Sentinel policies. Where should they configure these policies to run automatically on all runs?

Refer to the exhibit. A user encounters this error while running 'terraform plan'. What is the best course of action?

A team is using Terraform Cloud and wants to enforce that all AWS resources created by Terraform have a specific tag. Which feature should they use?

A team uses Terraform Cloud for remote state management. They want to ensure that state file changes are only made through the Terraform Cloud API and not through direct access to the storage backend. Which feature should they enable?

An operator runs `terraform apply` and receives an error that the state file is locked. What is the most likely cause?

Which TWO are valid methods to import existing infrastructure into Terraform?

A team has a monolithic Terraform configuration managing multiple AWS accounts. They want to decompose it into smaller configurations that can be managed independently. What is the recommended strategy?

A small startup is using Terraform to deploy AWS resources. They have two separate environments: development and production. Currently, they manage two sets of Terraform configuration files in different directories, each with its own state file stored locally. The CEO wants to reduce duplication and simplify management. The team decides to restructure into a single configuration with workspaces. After implementing workspaces, they run `terraform workspace new dev` and `terraform workspace new prod`, then `terraform apply` in the dev workspace. However, when they switch to prod and run `terraform apply`, the plan shows that Terraform wants to recreate all resources instead of managing the existing production resources. What is the most likely reason for this behavior?

A developer needs to inspect the current state of a specific resource managed by Terraform without modifying any infrastructure. Which command should they use?

Refer to the exhibit. Which command was most likely executed?

A company uses Terraform with a remote backend (AWS S3). They want to ensure that the state file is encrypted at rest. Which configuration approach guarantees this?

Refer to the exhibit. A team deploys this configuration. They run 'terraform apply' once and the instance is created. Later, they modify the instance type and run 'terraform apply' again. They notice the provisioner does not run on the second apply. Why?

Refer to the exhibit. The user runs 'terraform plan' and sees that Terraform wants to create the instance. However, the instance already exists in the AWS account with the same configuration. What is the most likely reason?

A company uses Terraform Cloud and wants to ensure that only approved modules from the private registry are used in configurations. How can they enforce this?

Which TWO of the following are valid ways to pass variables to Terraform in an automated pipeline?

You are managing a Terraform configuration that deploys resources across multiple AWS accounts using provider aliases. The configuration uses a single backend (S3) to store the state file. Recently, you discovered that the state file has become very large (over 100 MB) and is causing slow operations and timeouts. The team wants to improve performance without losing the ability to manage all resources with a single `terraform apply`. You need to propose a solution. Which approach should you take?

A small startup uses Terraform to manage infrastructure on AWS. They store the state file directly in a Git repository (gitignored but accidentally committed) and have no remote backend. The team has two engineers: Alice and Bob. They both run Terraform from their local machines. Recently, they experienced state conflicts where Alice's apply would succeed but subsequently Bob's apply would fail due to state drift. They want a simple solution without adding too much complexity. What should they do?

Which TWO of the following are valid ways to use Terraform outside the core workflow? (Choose two.)

A company uses Terraform Cloud and wants to enforce policies that all EC2 instances must be of type t2.micro or t2.small. Which feature should they use?

A company uses Terraform with a backend configured to store state in Azure Blob Storage. They want to view the current state of resources without performing a plan or apply. Which command should be used?

A company uses Terraform with multiple workspaces (dev, staging, prod) and a remote backend in an S3 bucket with a DynamoDB lock table. The backend configuration is defined in the main.tf with partial configuration. Developers are required to provide the backend configuration via command-line flags during 'terraform init'. One developer accidentally ran 'terraform init' without the required flags on a Monday morning. The init succeeded and created a local state file in the project directory. Over the next few days, other team members made changes to the workspace and pushed updates to the remote state. The developer who ran local init then runs 'terraform plan' and sees a plan that would recreate all resources. They realize their mistake. How can this situation be prevented in the future?

Which TWO Terraform backends support remote state locking?

During a CI/CD pipeline run, terraform apply fails halfway through due to a network error. The state file is locked. The team wants to resume from the last successful apply. What should they do?

You are a platform engineer at a large enterprise that uses Terraform Cloud with a VCS-backed workflow for all infrastructure. Your team manages a configuration that provisions AWS EC2 instances for a critical application. Recently, a junior team member accidentally committed a change that removed a required tag from the EC2 instance resource. The change passed the plan stage but was blocked by a Sentinel policy during the apply, preventing the infrastructure from being updated. The team needs to fix the configuration and apply the change. However, the repository is configured to automatically trigger runs on every push to the main branch. The team wants to avoid triggering an unwanted run while they work on the fix. What should the team do?

A company uses Terraform with multiple cloud providers and wants to integrate with their existing CI/CD pipeline. They need to enforce that all infrastructure changes go through code review and automated testing before being applied to production. Which approach best meets these requirements?

The user runs `terraform init` successfully, but then `terraform plan` still fails with a different error: "Error: No configuration files found in this directory." The directory contains backend.tf and main.tf. What is the most likely cause?

Which TWO statements about using Terraform with remote backends are correct?

Which THREE are valid use cases for the 'terraform state replace-provider' command?

An organization uses Terraform Cloud with a VCS-backed workspace connected to a GitHub repository. They want to trigger a speculative plan without creating a run (i.e., without costing compute resources or being displayed in the workspace). Which approach is appropriate?

A DevOps team manages infrastructure for a large e-commerce platform using Terraform with a remote backend in an S3 bucket with DynamoDB state locking. Recently, a team member ran `terraform apply` from their local machine but the command failed with the error: 'Error acquiring the state lock: ConditionalCheckFailedException: The conditional request failed'. The state file is not locked according to the DynamoDB table. After investigation, the team finds that the DynamoDB table has a TTL attribute enabled on the 'LockID' field, and old lock records are automatically deleted after a few minutes. The team suspects that another engineer's `terraform plan` process from a CI/CD pipeline might have created a lock that was subsequently deleted by TTL before it was released, causing the conflict. Which action should the team take to prevent this issue from recurring?

A CI/CD pipeline runs 'terraform plan' and needs to automatically approve only if no resources will be destroyed. Which approach should be used?

A developer accidentally deleted a resource from the Terraform state file using 'terraform state rm'. The resource still exists in the cloud provider. How can the developer re-import the resource without affecting other resources?

You are a platform engineer at a large e-commerce company that uses Terraform Enterprise to manage thousands of infrastructure resources across multiple teams. The company has a central 'networking' workspace that provisions shared VPCs and subnets, and several application workspaces that consume these networking resources via remote state data sources. Recently, the networking team changed the CIDR block of a shared subnet from '10.0.1.0/24' to '10.0.2.0/24' and applied the change successfully. However, the application teams are now reporting that their Terraform runs are failing with errors indicating that the subnet ID they reference does not exist. The application workspaces use the following configuration to consume the subnet: ```hcl data "terraform_remote_state" "networking" { backend = "remote" config = { organization = "mycompany" workspaces = { name = "networking" } } } resource "aws_instance" "app" { subnet_id = data.terraform_remote_state.networking.outputs.subnet_id ... } ``` The application workspaces have not been modified recently. The networking workspace output 'subnet_id' now contains the ID of the updated subnet. What is the most likely cause of the failures?

Which TWO are benefits of using Terraform Cloud's remote operations with a CLI-driven run workflow?

A company uses Terraform Cloud with a remote state backend and runs infrastructure as code through a CI/CD pipeline (GitHub Actions). The pipeline executes 'terraform plan' and 'terraform apply' using a service account with appropriate permissions. Recently, the team introduced a Sentinel policy to enforce that all AWS resources have mandatory tags (Environment, Owner, Project). The policy passes when runs are triggered manually from the Terraform Cloud UI, but fails consistently when the CI/CD pipeline runs the plan. The infrastructure configuration files are identical in both cases. The team verifies that the service account used by CI/CD has the same workspace permissions as the UI user. What is the most likely cause of the failure?
