A developer is converting a working JSON Packer template to HCL2. The JSON template has a builder with `"type": "virtualbox-iso"` and a provisioner with `"type": "shell"`. What is the correct HCL2 syntax for these blocks?

`builder "virtualbox-iso" { ... } provisioner "shell" { ... }`

`source "virtualbox-iso" "example" { ... } build { sources = ["source.virtualbox-iso.example"] }`

`build { sources = ["source.virtualbox-iso.example"] provisioner "shell" { ... } }`

`build { builder "virtualbox-iso" { ... } provisioner "shell" { ... } }`

An administrator is reviewing a legacy Packer template written in JSON. The template has a `builders` array, a `provisioners` array, and a `post-processors` array. The admin needs to add a variable that can be overridden from the command line. Where should this variable be defined in the JSON template?

In a top-level `variables` key.

In a separate `variables.json` file referenced by the template.

Inside the `builders` array as a `variable` key.

In the `provisioners` array as a `variable` key.

A systems engineer maintains a Packer template that builds an Ubuntu 22.04 VM for the company's on-premises VMware cluster. The template currently uses the `vmware-iso` builder. The team now also needs to produce an identical image for a small VirtualBox-based lab environment used by developers. The engineer wants to minimize duplication in the template while keeping the same provisioning steps for both targets. What should the engineer do?

Add a post-processor that converts the VMware image to VirtualBox format after the build completes.

Use the `virtualbox-iso` builder with a `source_path` pointing to the VMware output artifact.

Define both the `vmware-iso` and `virtualbox-iso` builders in the same `build` block, each referencing the same provisioner list.

Create a second template file that copies the provisioner blocks from the original and changes the builder to `virtualbox-iso`.
