GCP Professional Cloud Architect Practice Question

A data-engineering team is migrating a nightly log-processing workload to a single Compute Engine VM. The VM will attach a 10-TiB persistent disk, stream the log files sequentially for about 2 hours, write the summarized results, and then stay idle until the next night. They need to minimize storage cost, but they must sustain high sequential throughput; sub-millisecond latency or very high random IOPS are not required. Which persistent disk type should they choose?

  • Standard persistent disk (pd-standard)

  • Local SSD attached as a scratch disk

  • SSD persistent disk (pd-ssd)

  • Balanced persistent disk (pd-balanced)
