Correct Answer – D

Opion A – Write a lifecycle management rule in XML and push it to the bucket with gsutil:  you can set lifecycle configuration for an existing bucket with a PUT API call request (NOT the “gsutil lifecycle” command!). You must include an XML document in the request body that contains the lifecycle configuration. https://cloud.google.com/storage/docs/xml-api/put-bucket-lifecycle#request_body_elements

B and C can be eliminated. They do the similar thing slightly different:  write script listing object and get their timestamps

gsutil ls –[l or lr]  gs://[BUCKET_NAME]/**

If an object’s age is older than 90 days, do deleting,  then schedule a cron job for the recurring process.

However, gsutil ls -l/-lr does not list versioned objects. To list versioned object, need gsutil ls -a. Using this approach, versioned archives won’t be deleted.

There is a better, easier, and more consistent way to do this in Answer D

D (Correct answer) – Write a lifecycle management rule in JSON and push it to the bucket with gsutil.

To enable lifecycle management for a bucket: https://cloud.google.com/storage/docs/managing-lifecycles

·         Create a .json file with the lifecycle configuration rules you would like to apply (see examples below).

·         Use the lifecycle set command to apply the configuration

gsutil lifecycle set [LIFECYCLE_JSON-CONFIG_FILE] gs://[BUCKET_NAME]

The following lifecycle configuration JSON document specifies that all objects in this bucket that are more than 90 days old will be deleted automatically:

{
“rule”:
[
{
“action”: {“type”: “Delete”},
“condition”: {“age”: 90}
}
]
}
