Understand IaC concepts

A team is adopting Terraform to manage infrastructure. One requirement is that all configuration changes must be reviewed and approved before being applied. The team wants to ensure that the Terraform state file reflects the actual deployed infrastructure at all times. Which practice should they implement to meet these requirements?

An organization manages multiple environments (dev, staging, prod) using Terraform. They want to minimize code duplication while allowing environment-specific variable values. Which approach best achieves this goal?

A junior administrator wants to practice Terraform by deploying a single web server in AWS. They write a configuration file and run terraform init and terraform apply. The deployment succeeds but they notice the web server is not accessible from the internet. What is the most likely reason?

A company uses Terraform to manage infrastructure on AWS. They have a configuration that creates an S3 bucket and a DynamoDB table for state locking. The team notices that sometimes when two members run terraform apply simultaneously, they get a state locking error. However, they want to allow concurrent operations on different workspaces. What is the best approach?

Which THREE of the following are benefits of using Infrastructure as Code (IaC) compared to manual infrastructure management?

You are a DevOps engineer at a growing startup. The infrastructure currently consists of a single AWS EC2 instance running a web application, manually configured. The company plans to scale to multiple instances and environments (development, staging, production). They want to adopt Infrastructure as Code using Terraform. The team has limited experience with Terraform and wants to start small, then gradually adopt more advanced features. The current manual infrastructure must be imported into Terraform. The team also wants to ensure that code changes are reviewed via pull requests before being applied. Which of the following is the best course of action to meet these requirements?

Which TWO statements about Infrastructure as Code (IaC) are correct?

A developer runs terraform apply with the configuration above. The resource is created successfully, but the provisioner fails because the public_ip attribute is not yet known at plan time. What is the most likely cause?

You are a platform engineer at a growing startup. The company currently manages infrastructure manually by SSH-ing into servers to install packages and update configurations. As the team grows, this approach has led to frequent configuration drift, inconsistent environments, and manual errors. Deploying a new environment takes several days and requires detailed runbooks. The CTO has asked you to propose a solution that improves consistency, reduces deployment time, and enables version control of infrastructure. You are evaluating Infrastructure as Code (IaC) tools like Terraform. Which course of action best addresses the CTO's requirements?

An organization wants to ensure that running the same Terraform configuration multiple times produces the same result without unintended changes. Which IaC concept is most critical for this goal?

A team is evaluating Terraform and Ansible for infrastructure provisioning. They note that Terraform describes the desired end state, while Ansible defines steps to reach that state. This difference is best described as:

A team of five engineers uses Terraform with a remote backend in AWS S3 with DynamoDB state locking. One engineer runs 'terraform apply' but it hangs at 'Acquiring state lock'. What is the most likely cause?

A user runs 'terraform plan' and gets an error: 'No state file was found!'. Which is the most likely cause?

A company has a Terraform module that creates an AWS VPC with subnets. They want to reuse this module across multiple AWS accounts. What is the best practice for referencing the module from different root configurations?

During development, a Terraform user wants to check that their configuration is syntactically valid and internally consistent before running 'terraform plan'. Which command should they use?

A Terraform configuration includes a variable for a database password marked as sensitive. When a user runs 'terraform apply', the password appears as (sensitive) in the plan output. However, they want to pass this password to a provisioner as an environment variable. What should they do?

A Terraform user wants to visualize the execution order of resources before applying changes. Which command provides a dependency graph view?

A team uses Terraform to manage multiple AWS EC2 instances with a 'count' meta-argument. They need to reference the ID of the third instance in another resource's configuration. Which expression should they use?

An organization uses Terraform Cloud with VCS-driven runs. They have two workspaces: network and application. They want a new run in the application workspace to automatically trigger whenever the network workspace completes a successful plan. What should they configure?

Which two are primary benefits of using Infrastructure as Code (IaC) with Terraform?

Which three characteristics are associated with immutable infrastructure as practiced by Terraform?

Which two commands are part of the standard Terraform workflow for provisioning infrastructure?

Based on the exhibit, what can be inferred about the Terraform state and configuration?

After applying the configuration above, the user changes the AMI to a new value and runs 'terraform apply'. Assuming the new AMI triggers a recreate, what happens during the apply?

A team uses the backend configuration above. What is the primary benefit of storing state remotely in S3?

A team wants to ensure that their infrastructure configuration repeatedly results in the same environment regardless of the initial state. Which IaC concept is most directly associated with this goal?

A development team is using a declarative IaC tool. They make a change to the configuration file to add a new security group rule. When they apply the configuration, the tool automatically modifies the existing security group to add the rule. What is this behavior called?

An organization is evaluating IaC tools and wants to minimize configuration drift. Which characteristic of a declarative IaC approach is most effective in preventing drift?

Which of the following is a primary benefit of using Infrastructure as Code?

A company is managing multiple cloud environments (dev, test, prod) using Terraform. They want to ensure consistent configurations across environments while allowing environment-specific values. Which IaC practice best supports this?

A team uses Terraform to manage AWS resources. After a manual change to an S3 bucket policy through the AWS console, Terraform's next plan shows that it will revert the policy to the configuration. This is an example of which concept?

Which statement best describes 'immutable infrastructure' in the context of IaC?

A company uses Terraform to deploy virtual machines. They want to ensure that the same exact operating system and software versions are used every time. Which practice supports this?

In Terraform, the `terraform plan` command compares the current state with the configuration. This is an example of which IaC principle?

Which two are benefits of using Infrastructure as Code? (Choose two.)

Which three practices help maintain consistency and reduce configuration drift in IaC? (Choose three.)

Which two statements accurately describe the difference between declarative and imperative IaC approaches? (Choose two.)

Refer to the exhibit. A team is using this S3 backend configuration. During a deployment, they receive an error that the state file is locked. What is the most likely cause?

Refer to the exhibit. After applying this configuration, a team member manually changes the instance type to 't2.small' via the AWS console. The next `terraform plan` shows a change to revert to 't2.micro'. What does this demonstrate?

A company manages a microservices application across multiple AWS accounts using Terraform. They have a dedicated 'infrastructure' repository with Terraform configurations for each account. The team recently migrated their Terraform state to a centralized S3 backend with DynamoDB locking. After the migration, they notice that when two developers run `terraform apply` simultaneously in the same workspace, one of them receives a lock error, but the other proceeds normally. The team wants to ensure that only one apply runs at a time across all workspaces. However, they also need to allow concurrent operations on different workspaces. The current backend configuration uses a single DynamoDB table for all workspaces. What should the team do to achieve their goals?

A startup is adopting Terraform to manage their cloud infrastructure. They want to ensure that changes to infrastructure are reviewed and approved before being applied. Which practice aligns with Infrastructure as Code principles to achieve this?

A team is defining their Infrastructure as Code strategy. Which two of the following are key benefits of using IaC compared to manual configuration?

A company manages multiple AWS accounts using Terraform. They have a central repository where all Terraform configurations are stored. Recently, a developer accidentally ran terraform destroy on a production workspace and deleted critical resources. The team wants to implement safeguards to prevent such incidents while still allowing developers to test changes in non-production environments. They currently use Terraform Cloud for remote state management and runs. Which course of action should the team take to minimize risk?

Which TWO statements correctly describe Infrastructure as Code principles?

Refer to the exhibit. What will happen when you run terraform plan?

A team manages a multi-tier application consisting of web servers, application servers, and databases deployed across AWS and Azure. Historically, they have provisioned infrastructure manually using cloud consoles and ad-hoc scripts. To improve consistency and reduce errors, they decide to adopt Terraform for Infrastructure as Code. After initial rollout, they encounter problems: some team members still make direct changes via the cloud console to quickly fix issues, causing configuration drift between the Terraform state and actual resources. They also need to manage three distinct environments (development, staging, production) with different configurations (e.g., instance sizes, database settings). The team consists of five people with a limited budget for additional tools. Which course of action best addresses these challenges while adhering to IaC principles?
