A1. Update your instances' metadata to add the following value: snapshot--schedule: 0 1 * * *
2. Update your instances' metadata to add the following value: snapshot--retention: 30

B1. In the Cloud Console, go to the Compute Engine Disks page and select your instance's disk.
2. In the Snapshot Schedule section, select Create Schedule and configure the following parameters:
-- Schedule frequency: Daily
-- Start time: 1:00 AM -- 2:00 AM
-- Autodelete snapshots after 30 days

C1. Create a Cloud Function that creates a snapshot of your instance's disk.
2. Create a Cloud Function that deletes snapshots that are older than 30 days.
3. Use Cloud Scheduler to trigger both Cloud Functions daily at 1:00 AM.

D1. Create a bash script in the instance that copies the content of the disk to Cloud Storage.
2. Create a bash script in the instance that deletes data older than 30 days in the backup Cloud Storage bucket.

I thought snapshots were kept indefinitely unless you delete them.

Wait, why would you create Cloud Functions for this? Seems overkill.

I recall we discussed option D in class, but using bash scripts feels risky. I’d prefer a more integrated solution like B.

I'm not entirely sure about the metadata update in option A. I remember something about it, but it feels a bit more manual than what we practiced.

I think option B sounds familiar; it seems like the easiest way to set up a snapshot schedule directly in the console.

Option C seems complicated with the Cloud Functions and Cloud Scheduler. I feel like it adds unnecessary complexity for just backing up an instance.

I'm a bit confused by this question. Is the Android library code really organized in a way that allows it to be used by multiple apps? I'll have to review my notes on Android development to be sure.

I'm a little confused by the wording of the options. Are they all referring to the same type of form, or could it be different types of forms? I'll need to think about the context and the specific scenarios where a Submit button would appear.

Okay, I think I can handle this. Applying the Jump & Turn effect to the 3D model on slide 3 should be straightforward.
