Difficulty: EasyPlanning Cloud Storage Buckets and Storage Classes

A system administrator needs to store software installation packages and container base images in a Google Cloud Storage bucket. These artifacts are downloaded multiple times per hour by CI/CD build pipelines and development teams. Which Cloud Storage class should be selected as the default storage class for the bucket to provide high availability without incurring retrieval fees?

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

Answer

Standard Storage
Standard Storage is the optimal choice for active, frequently accessed data such as software dependencies and container images used in CI/CD pipelines because it provides low latency access without charging any data retrieval fees.

Step-by-Step Solution

1
Analyze the workload data access pattern
The build artifacts are accessed continuously multiple times per hour.
Access frequency dictates the optimal Cloud Storage tier to minimize total cost of ownership.
2
Evaluate retrieval cost structures across storage classes
Standard Storage carries zero retrieval fee per GB, whereas Nearline, Coldline, and Archive impose retrieval fees.
For high-frequency read operations, data retrieval charges in colder storage classes quickly outweigh any at-rest storage savings.
