Difficulty: HardManaging and Requesting GCP Resource Quotas

A cloud administrator is tasked with scaling a high-throughput event processing platform in Google Cloud Project `stream-data-prod`. The platform requires deploying additional Compute Engine virtual machines in the `us-central1` region. However, automated scripts fail with an error stating that the regional `In-Use IP addresses` quota limit has been reached. To enable the deployment while following Google Cloud best practices and the principle of least privilege, what action should be taken?

  1. Assign the Quota Administrator role (`roles/servicemanagement.quotaAdmin`) to the administrator, and submit a quota increase request for the `In-Use IP addresses` metric in `us-central1` through the Quotas page in the Google Cloud Console.Answer
  2. B
    Deploy the additional Virtual Machines into a secondary region such as `us-east1` without requesting a quota adjustment, as regional limits automatically balance across active regions.
  3. C
    Assign the Project Owner primitive role (`roles/owner`) to the administrator, as primitive roles are mandatory for approving and executing GCP resource quota adjustments.
  4. D
    Increase the budget alert threshold on the linked Billing Account so that Google Cloud automatically expands the regional quota ceiling upon reaching 100% capacity.

Answer

Assign the Quota Administrator role (`roles/servicemanagement.quotaAdmin`) to the administrator, and submit a quota increase request for the `In-Use IP addresses` metric in `us-central1` through the Quotas page in the Google Cloud Console.
To increase a GCP resource quota, an administrator must request a quota increase through the Google Cloud Console Quotas page. Following the principle of least privilege, the administrator should be assigned the predefined Quota Administrator role (`roles/servicemanagement.quotaAdmin`), which provides the necessary permissions without granting unnecessary administrative rights over other resources.

Step-by-Step Solution

1
Identify the root cause of the deployment failure
The failure stems from exceeding the regional ceiling for `In-Use IP addresses` in `us-central1`.
Google Cloud enforces hard regional limits on specific infrastructure metrics to ensure fair allocation and platform stability.
2
Determine the required IAM role adhering to least privilege
Select `roles/servicemanagement.quotaAdmin` (Quota Administrator).
This predefined role provides specific permissions (`serviceusage.quotas.update`) required to request quota increases without granting administrative access over other GCP resources.
3
Submit the request through official GCP administration tooling
Navigate to IAM & Admin > Quotas in the Google Cloud Console, select `In-Use IP addresses` for `us-central1`, click Edit Quotas, and submit the requested increase.
Formal quota requests are evaluated by Google Cloud automated systems or support to approve higher limits.
