LPI 305-300 Exam - Topic 1 Question 45 Discussion

How does Packer interact with system images?
E) Packer creates an instance based on a source image, prepares the instance through a network connection and bundles the resulting instance as a new system image.
A) Packer has to be installed within the target image and is executed during the image's first boot in order to execute preparation tasks.
B) Packer installs a client within the image which has to be run periodically via cron in order to retrieve the latest template from the Packer server and apply it locally.
C) Packer periodically connects through the network to the Packer daemons of all running Packer images in order to re-apply the whole template to the running instance.
D) Packer downloads and extracts an image in order to make changes to the image's file system, repack the modified image and upload it again.

C is confusing. Packer doesn’t re-apply templates like that.

B sounds complicated. I don’t see why Packer would need a client in the image.

I feel like D makes sense too, but it’s more about modifying than creating.

I practiced a similar question where Packer was described as modifying images, but I can't remember if it was about downloading and extracting or just creating new instances.

I think option E sounds right because it mentions preparing the instance through a network connection, which is something I practiced in the labs.

I remember studying that Packer creates an instance from a source image, but I'm not sure if it bundles it as a new system image or just modifies it.

I'm leaning towards B, where Packer installs a client within the image that periodically retrieves updates from the Packer server. That would make sense for keeping images up-to-date, but I'm not 100% sure if that's how Packer actually works.

I'm pretty confident that E is the correct answer. Packer creates a new image by provisioning an instance from a source image and then bundling that instance into a new image. The network connection is key for Packer to interact with the instance during the preparation process.

Option D sounds right to me. Packer downloads the image, makes changes to the file system, and then repacks the modified image. That seems to fit with how I understand Packer works.

I'm a bit confused on this one. I know Packer is used to create images, but I'm not sure if it actually connects to the running instances or just modifies the image files directly. I'll have to think this through a bit more.

I think option E is the way to go here. Packer creates a new image based on a source image, and it does this by connecting to the instance over the network to prepare it.
