Difficulty: EasyManaging Storage and Database Solutions

A system administrator manages a Cloud Storage bucket containing application log files. The logs are frequently inspected during the first 30 days after creation, but are accessed only occasionally after 30 days. To automatically reduce storage costs without deleting any data or manually moving files, which action should you perform?

  1. Configure an Object Lifecycle Management rule on the bucket to transition objects to Nearline Storage after 30 days.Answer
  2. B
    Change the default storage class of the Cloud Storage bucket to Archive Storage immediately upon creation.
  3. C
    Migrate all existing and incoming log data into Cloud Bigtable to lower overall per-gigabyte storage fees.
  4. D
    Execute a daily gsutil command script to copy objects older than 30 days into a secondary bucket with Uniform Bucket-Level Access disabled.

Answer

Configure an Object Lifecycle Management rule on the bucket to transition objects to Nearline Storage after 30 days.
Object Lifecycle Management rules allow setting lifecycle conditions (such as Age = 30 days) to automatically transition objects from Standard to Nearline storage, optimizing storage costs according to access frequency.

Step-by-Step Solution

1
Analyze access patterns
Logs are accessed frequently for 30 days, then infrequently afterwards.
Nearline storage is ideal for data accessed less than once a month.
2
Identify the automated management mechanism in Cloud Storage
Object Lifecycle Management allows setting rules based on conditions like object age.
Automating object class transition eliminates manual scripting and operational overhead.
