Difficulty: HardManaging Compute Engine Resources

An enterprise organization hosts a mission-critical web application on Compute Engine instances located in the europe-west1 region. During a planned capacity expansion, a Cloud Engineer attempts to launch 20 additional n2-standard-16 virtual machines within europe-west1-b. The creation request fails immediately with a QUOTA_EXCEEDED error indicating that the N2_CPUS regional quota limit has been reached. Due to strict data residency and VPC peering requirements, the workload must remain within the europe-west1 region. Which action should the engineer take to successfully provision the required compute capacity while following Google-recommended best practices?

  1. Submit a quota increase request for the N2_CPUS regional metric in europe-west1 via the Cloud Console IAM & Admin Quotas page.Answer
  2. B
    Create a secondary Virtual Private Cloud (VPC) network within europe-west1-b to reset the regional CPU quota counters for the project.
  3. C
    Reconfigure the VM provisioning deployment to use Spot VM instances, which are exempt from regional CPU quota limits.
  4. D
    Assign the primitive Owner role (roles/owner) to the service account provisioning the VMs to bypass project-level quota restrictions.

Answer

Submitting a quota increase request for the N2_CPUS regional metric in europe-west1 via the Cloud Console IAM & Admin Quotas page is the correct action.
The correct option is submitting a quota increase request via the Cloud Console IAM & Admin Quotas page. Google Cloud quotas are default safety limits placed on project resources per region or zone. When a valid operational need requires higher capacity within a specific region, administrative users must formally request a quota increase through the console or gcloud CLI.

Step-by-Step Solution

1
Identify the cause of the failure from the error message.
The failure is caused by reaching the regional N2_CPUS quota ceiling in europe-west1.
Google Cloud enforces hard default limits on regional vCPU usage to prevent accidental cost overruns and maintain capacity.
2
Evaluate alternative workaround suggestions against GCP architecture constraints.
Creating new VPCs, changing IAM roles, or using Spot VMs does not bypass standard regional CPU quota limits for mission-critical workloads.
Quotas are enforced at the project/region level by the GCP control plane regardless of networking configuration or IAM privilege level.
3
Execute the Google-recommended operational workflow for capacity adjustments.
Navigate to IAM & Admin > Quotas in the Google Cloud Console, select the N2_CPUS metric for europe-west1, and submit an edit request with justification.
Quota increase requests allow Google Cloud to evaluate capacity allocations and safely expand resource limits for the project.
