AWS and Terraform Quiz

Your team is using Terraform to manage AWS resources. You run terraform apply to create an EC2 instance, but you realize the instance wasn't created. What is the most likely cause?

• The EC2 instance type was incorrect in the Terraform script.

• The terraform apply command needs to be run with -force flag.

• The AWS provider in the Terraform configuration is incorrectly set up.

• The instance was already running and Terraform couldn't detect it.

In a CloudFormation template, you are creating an EC2 instance but the instance fails to launch. What is the first step in troubleshooting this issue?

• Check the CloudFormation stack's error logs in the console.

• Delete the stack and recreate it.

• Ensure that the EC2 instance type is correct.

• Restart the CloudFormation service.

You are using Jenkins to automate deployment to AWS S3. The deployment fails because of access issues. What could be the issue?

• The S3 bucket versioning is disabled.

• Jenkins lacks the proper AWS credentials.

• Jenkins is configured for the wrong AWS region.

• The S3 bucket is configured to allow only public access.

You are deploying a static website to AWS S3 using a CI/CD pipeline. After deployment, users report slow page loads. What should you do to improve this?

• Switch to using EC2 instead of S3 for static website hosting.

• Enable Amazon CloudFront to cache content closer to users.

• Increase the number of EC2 instances.

• Configure the S3 bucket for versioning.

You are using Terraform to automate the provisioning of a VPC, but it fails. What would be the first thing to check?

• The AWS CLI is not installed.

• The IAM permissions associated with Terraform are not sufficient.

• There is a network connectivity issue.

• The terraform plan step was not executed before apply.

In a CloudFormation template, you need to define a security group to allow HTTP access to an EC2 instance. Which configuration would you use?

• Use a Type: SecurityGroup resource and configure Port: 443.

• Use a Type: SecurityGroup resource and configure Port: 80.

• Define an IAM role for the EC2 instance with HTTP access.

• Define a Lambda function to handle incoming HTTP traffic.

You have a CI/CD pipeline configured in Jenkins to deploy code to an EC2 instance. The Jenkins job fails with an error related to security credentials. What is the likely cause?

• Jenkins is missing a valid SSH key to access EC2.

• EC2 has reached its maximum instance limit.

• The Jenkins server is out of disk space.

• The IAM role attached to the EC2 instance doesn't have the correct permissions.

You are deploying a Lambda function with CloudFormation. After deployment, the Lambda function does not execute. What should you check first?

• Ensure the Lambda function has the correct IAM execution role.

• Make sure that CloudFormation stack has no errors.

• Check if the function is configured with the correct runtime version.

• All of the above.

In your CI/CD pipeline, Jenkins is configured to deploy an application to an S3 bucket. However, users report that the changes are not reflected. What is most likely causing the issue?

• The S3 bucket is not configured for static website hosting.

• Jenkins is not running the deploy job automatically.

• Jenkins failed to invalidate the CloudFront cache.

• The S3 bucket has incorrect region settings.

When using Terraform to provision a VPC on AWS, which resource is required to allow internet traffic to the VPC?

• aws_nat_gateway

• aws_route_table

• aws_internet_gateway

• aws_security_group
