Zorluk: OrtaPlanning Cloud Storage Buckets and Storage Classes

A multinational retail company generates end-of-day point-of-sale (POS) transaction files that are stored in Google Cloud Storage. Finance teams access these files daily during the first 30 days to complete inventory and sales reconciliation. After 30 days, the files are rarely accessed but must be retained for 5 years for legal compliance. Which storage bucket lifecycle configuration minimizes total storage and retrieval costs while satisfying these access requirements?

  1. A
    Deploy a bucket with the default storage class set to Archive Storage, and store all POS transaction files in this bucket from creation.
  2. Deploy a bucket with the default storage class set to Standard Storage, and configure an Object Lifecycle Management rule to transition objects to Archive Storage after 30 days.Cevap
  3. C
    Deploy a bucket with the default storage class set to Standard Storage, and configure an Object Lifecycle Management rule to transition objects to Coldline Storage on day 5 of creation.
  4. D
    Deploy a bucket with Uniform Bucket-Level Access disabled, set the bucket default class to Standard Storage, and apply individual object ACLs to change object storage classes to Archive Storage after 30 days.

Cevap

Deploy a bucket with the default storage class set to Standard Storage, and configure an Object Lifecycle Management rule to transition objects to Archive Storage after 30 days.
Standard Storage provides zero retrieval fees during the active 30-day period when finance teams access POS files daily. Transitioning objects to Archive Storage after 30 days reduces ongoing monthly storage costs to the lowest tier for the remaining 5-year compliance retention window.

Adım Adım Çözüm

1
Analyze access patterns during the initial phase.
Files are accessed daily during the first 30 days, requiring a storage class with zero retrieval fees, such as Standard Storage.
Choosing Nearline, Coldline, or Archive during the active 30-day window would result in substantial data retrieval charges.
2
Analyze long-term retention and access requirements.
After 30 days, data access becomes extremely rare (less than once per year) over a 5-year retention period, making Archive Storage the most cost-effective tier.
Archive Storage offers the lowest per-gigabyte monthly storage cost for long-term archival data.
3
Select the automated management mechanism.
Use Object Lifecycle Management to automatically transition objects from Standard Storage to Archive Storage 30 days after object creation.
Lifecycle rules natively automate class transitions without manual intervention or custom application scripts.

Anahtar Kavram

Selecting Cloud Storage classes and automating transitions using Object Lifecycle Management based on access frequency and retrieval costs.
