Exam Professional Cloud Architect topic 1 question 17 discussion

All four are correct answers. Google has built in cron job schduling with Cloud Schedule, so that would place "D" behind "C" in Google's perspective. Google also has it's own lifecycle management command line prompt gcloud lifecycle so "A" or "B" could be used. JSON is slightly faster than XML because of the "{" verse "<c>" distinguisher, with a Trie tree used for alphanumeric parsing. So between "A" and "B", choose "B". Between "B" and "A", "B" is slightly more efficient from the GCP operator perspective. So choose "B".

I'll go with B. A is not reasonable because life cycle policies are not written in XML. B is reasonable and is cloud native. C requires a cron script which needs something to run the script and is a non-cloud native approach. D requires a cron script which needs something to run the script and is a non-cloud native approach.

1. Lifecycle Management: Google Cloud Storage offers built-in lifecycle management rules specifically designed for automated data retention and deletion. This is the most efficient and cost-effective way to manage your backup files. 2. JSON Format: Lifecycle rules are defined in JSON format. 3. gsutil: The gsutil command-line tool is used to interact with Cloud Storage, including setting lifecycle configuration.

choose B

The correct available answer is B. But in real life, we use Terraform tfvars file.

Cloud Storage has lifecycle management rules and could be applied with gsutil and gcloud storage buckets. It is common to use JSON for transferring data.

B, gsutil can set policy using json file https://cloud.google.com/storage/docs/gsutil/commands/lifecycle#examples

To remove backup files older than 90 days from a Cloud Storage bucket and optimize ongoing Cloud Storage spend, you should consider writing a lifecycle management rule in JSON and pushing it to the bucket with gsutil, as described in option B. Lifecycle management rules allow you to automatically delete objects from a Cloud Storage bucket based on age or other criteria, such as the object's storage class. By writing a rule in JSON and pushing it to the bucket with gsutil, you can specify that objects older than 90 days should be deleted, ensuring that the bucket only contains current backup files and minimizing Cloud Storage spend. Option A, C and D would not be suitable for this use case, as they do not allow you to specify lifecycle management rules that delete objects based on age.

B. Write a lifecycle management rule in JSON and push it to the bucket with gsutil To remove backup files older than 90 days from a Cloud Storage bucket, you can use the lifecycle management feature in Cloud Storage. This feature allows you to specify rules to automatically delete objects based on their age.

B. Life cycle management using JSON.

B with JSON option is correct

B is ok

B is the right answer

life cycle management is the answer written in JSON format. JSON is easier to write and read compared to XML which you can not use in commands

Lifecycle management with JSON is right .. I will go with B

B. Write a lifecycle management rule in JSON and push it to the bucket with gsutil
