Read the first 6 Cloud Engineer Cost Optimization & Resource Management flashcards as text

  1. Which Cloud Storage class is most cost-effective for data accessed less than once a year?

    Answer: Archive

    Archive storage has the lowest storage cost but highest retrieval cost, designed for data accessed fewer than once per year such as long-term backups and disaster recovery.

  2. What is the primary benefit of using custom machine types in Compute Engine?

    Answer: They allow you to specify exact vCPU and memory ratios to avoid paying for unused resources

    Custom machine types let you choose the exact number of vCPUs and amount of memory your workload needs, avoiding the waste of over-provisioning with fixed predefined machine types.

  3. Which BigQuery feature eliminates the need to manage cluster sizing and charges only for data scanned?

    Answer: BigQuery on-demand pricing

    BigQuery on-demand pricing charges per TB of data scanned, with no infrastructure to manage, making it cost-efficient for variable or unpredictable query workloads.

  4. What GCP feature allows you to export detailed billing data to BigQuery for advanced cost analysis?

    Answer: Cloud Billing data export to BigQuery

    Cloud Billing export to BigQuery streams all billing data (usage, cost, credits) into a BigQuery dataset for custom queries, dashboards, and cost allocation reports.

  5. A team deployed several test VMs that are now idle. Which GCP tool will proactively identify these idle VMs and suggest deleting them?

    Answer: Google Cloud Recommender (idle VM recommendation)

    Google Cloud Recommender provides idle VM recommendations by identifying instances with low CPU utilization over a rolling 14-day window and suggesting they be stopped or deleted.

  6. What is a GCP Commitment (CUD) applied to in terms of scope?

    Answer: A specific region and machine family

    Committed Use Discounts are scoped to a specific region and machine family (e.g., N2 in us-central1), and the discount applies to any matching usage within that scope.
