Difficulty: EasyPlanning Cloud Storage Buckets and Storage Classes

A financial technology company needs to store historical customer transaction receipts in Google Cloud Storage for 5 years to meet regulatory compliance requirements. These receipts are expected to be accessed less than once per year, but when requested for an audit, they must be retrieved immediately within milliseconds. Which Cloud Storage class provides the lowest storage cost for this access pattern?

  1. Archive StorageAnswer
  2. B
    Coldline Storage
  3. C
    Nearline Storage
  4. D
    Standard Storage

Answer

Archive Storage is the most cost-effective Google Cloud Storage class for data accessed less than once per year while providing millisecond retrieval times.
Archive Storage is optimized for long-term digital preservation and data accessed less than once per year. It provides the lowest per-gigabyte monthly storage cost among Google Cloud Storage classes while preserving instant (millisecond) access.

Step-by-Step Solution

1
Analyze the data access frequency and latency requirements.
Access frequency is less than once per year, and data must be retrievable within milliseconds.
Google Cloud Storage classes differ primarily by minimum storage duration, access frequency optimization, and per-GB storage vs. retrieval costs.
2
Evaluate Google Cloud Storage classes based on the annual access pattern.
Archive Storage is specifically designed for data accessed less than once a year (365-day minimum duration) and offers the lowest monthly storage cost among all GCS tiers without sacrificing millisecond access time.
Choosing Archive Storage minimizes total cost of ownership for long-term compliance archives.

Key Concept

Selecting Cloud Storage classes based on access frequency, retention period, and cost optimization.
