Zorluk: OrtaProvisioning Compute Engine and Kubernetes Engine Clusters

An enterprise financial service relies on automated scripts to provision a temporary managed instance group (MIG) of Compute Engine virtual machines every midnight to process end-of-day ledger reconciliations. During scale testing for an upcoming release requiring 500500 N2 vCPUs in the `us-central1` region, the deployment script fails to scale up beyond 100100 vCPUs, despite using valid credentials and validated Infrastructure as Code templates. Which action should the Cloud Architect take to resolve this provisioning failure?

  1. Request a regional N2 vCPU quota increase for `us-central1` through Cloud Quotas before running the large-scale batch workload.Cevap
  2. B
    Grant the deployment service account the Service Account Admin role to bypass regional resource provisioning boundaries.
  3. C
    Migrate the batch reconciliation script into a Google Kubernetes Engine cluster to eliminate Compute Engine vCPU quota restrictions.
  4. D
    Assign the primitive Project Owner role to the instance template's service account to unlock unrestricted instance creation capability.

Cevap

Request a regional N2 vCPU quota increase for `us-central1` through Cloud Quotas before running the large-scale batch workload.
The correct answer correctly identifies that Google Cloud projects have default regional quotas for machine families (such as N2 vCPUs). When automated provisioning fails at a specific numeric ceiling despite correct IAM permissions and IaC code, the limiting factor is regional quota. Proactively requesting a quota increase for the target region resolves the provisioning ceiling.

Adım Adım Çözüm

1
Identify the root cause of the provisioning cap at 100 vCPUs.
Recognize that default regional Compute Engine quota limits for specific machine families (such as N2 vCPUs in `us-central1`) restrict resource allocation regardless of IAM permissions.
Google Cloud enforces default resource quotas on projects to prevent unexpected spend and ensure fair resource distribution across regions.
2
Evaluate potential solutions to allow scaling to 500 vCPUs.
Determine that submitting a quota increase request for regional N2 vCPUs in `us-central1` directly addresses the provisioning constraint.
Quota adjustments must be requested and approved ahead of large-scale provisioning events.
