A company currently uses manual configuration of VMs for each new environment, which is slow and inconsistent. They want to adopt a tool that creates identical, pre-configured VM images for both on-premises VMware and AWS. Which tool and approach best fits this requirement?

Use Terraform to build and configure VMs on both platforms.

Use Ansible to provision VMs directly on both platforms without creating images.

Use Vagrant to create and configure VMs on both platforms.

Use Packer with multiple builders in a single template to create images for both VMware and AWS.

A junior admin runs `packer build template.pkr.hcl` and receives an error stating that a required variable `iso_checksum` is not set. The admin checks the template and sees the variable declared but no default value. What is the correct way to proceed?

Run `packer build -auto-install template.pkr.hcl`.

Run `packer build template.pkr.hcl` again; the error is transient.

Run `packer validate template.pkr.hcl` to fix the error.

Run `packer build -var iso_checksum=... template.pkr.hcl`.

A team has a Packer template that builds a CentOS image. They need to pass a secret API token to a script during provisioning. The token is stored in a CI/CD pipeline secret. The team wants to avoid hard-coding the token in the template or committing it to version control. What is the most secure approach?

Use an environment variable in the CI/CD pipeline and reference it in the template with `{{ env "API_TOKEN" }}`.

Hard-code the token in the provisioner script.

Use a variable with a default value set to the token.

Use a `local` block to read the token from a file.

What is the output of a successful Packer build?

A log file of the build process.

A reusable machine image artifact.

A configuration management script.
