What is the primary purpose of HashiCorp Packer in the context of VM deployment and provisioning?

To orchestrate the deployment of containerized applications across a cluster of hosts.

To manage the runtime lifecycle of running virtual machines, such as starting, stopping, and monitoring them.

To create identical machine images for multiple platforms from a single source configuration.

To provide a configuration management language for defining the desired state of servers.

In a Packer template, what is the purpose of defining a 'source' block?

To define the software packages that will be installed by the provisioners.

To specify the output location for the built artifact.

To declare variables that can be used across the template.

To specify the base image and builder configuration that will be used to create the machine image.

A build engineer runs `packer build` on a template that uses the `qemu` builder. The build fails during the boot phase because the VM cannot find the ISO. The engineer confirms the ISO URL is correct and accessible from the build host. What is the most likely cause?

The `output_directory` is not writable.

The `boot_command` is incorrect or missing for the target OS.

The `iso_checksum` value in the template does not match the actual ISO file.

The `ssh_username` is not set in the builder.

A Packer template builds a Windows image and uses a `powershell` provisioner to install software. The build succeeds, but the resulting image has unnecessary temporary files from the installation. The team wants to clean these files before the image is finalized. What is the best approach?

Add a post-processor to clean the files after the build.

Add a `powershell` provisioner at the end of the provisioner list that deletes the temporary files.

Use a `file` provisioner to delete the temporary files.

Modify the installer script to clean up after itself.
