Zorluk: Çok zorManaging Storage and Database Solutions

Your organization stores daily transaction log files in a Cloud Storage bucket configured with Uniform Bucket-Level Access. An automated compliance audit script accesses and inspects all log files daily during the first 60 days following their creation. Currently, an Object Lifecycle Management rule immediately transitions all uploaded objects to the Archive storage class upon creation, resulting in substantial retrieval fee charges during the daily compliance audits. You need to reconfigure the operational storage strategy to minimize overall storage and retrieval costs without compromising daily audit access or altering bucket access control policies. Which action should you take?

  1. Update the Object Lifecycle Management rule to keep objects in the Standard storage class for 60 days before transitioning them to the Archive storage class.Cevap
  2. B
    Maintain immediate transition to Archive storage upon upload and grant the audit service account direct Object Viewer permissions to waive data retrieval fees.
  3. C
    Disable Uniform Bucket-Level Access on the bucket and set individual fine-grained Object ACLs to allow free retrieval for the compliance audit script.
  4. D
    Migrate the transaction log files to a Cloud Bigtable instance with HDD storage nodes to eliminate object retrieval costs during daily reads.

Cevap

Update the Object Lifecycle Management rule to keep objects in the Standard storage class for 60 days before transitioning them to the Archive storage class.
Cloud Storage pricing consists of storage capacity fees and operational/retrieval fees. While Archive storage offers the lowest monthly capacity rates, reading data from Archive storage incurs significant data retrieval fees. When data is accessed daily for 60 days, storing it in the Standard storage class during that active 60-day window avoids retrieval charges completely. Setting the lifecycle rule condition `age: 60` before executing `SetStorageClass: ARCHIVE` optimizes total operational expenditure.

Adım Adım Çözüm

1
Analyze data access patterns and cost drivers.
Identified that objects are accessed daily for 60 days. Archival storage classes (Nearline, Coldline, Archive) incur significant per-GB retrieval fees when accessed frequently.
Immediate transition to Archive storage causes high data retrieval charges during the 60-day active audit period.
2
Evaluate Object Lifecycle Management lifecycle conditions.
Determined that adding an Age condition of 60 days for the SetStorageClass action retains objects in Standard storage during active reading.
Standard storage has higher monthly capacity costs but zero retrieval fees, making it optimal for active data.
3
Verify compliance with security and operational constraints.
Uniform Bucket-Level Access remains enabled and compliant with organizational access policies.
Lifecycle rules operate independently of bucket-level IAM policies without requiring security policy modifications.
