GCP PCA · Question 28 · Domain 4: Analyzing and Optimizing Technical and Business Processes

Your company is planning a massive marketing campaign that will launch in 48 hours. The engineering team expects a 20x increase in traffic. The application runs on Compute Engine instances in the us-central1 region. During a load test, the autoscaler failed to provision enough instances, and the logs showed QUOTA_EXCEEDED errors for N2 CPUs. What is the most appropriate action to ensure the campaign's success?

Answer options:

A.

Change the instance type to E2 to bypass the N2 quota limit.

B.

Deploy the application to AWS to handle the overflow traffic.

C.

Submit a quota increase request for N2 CPUs in us-central1 via the Google Cloud Console immediately.

D.

Disable the quota limits in the IAM & Admin settings.

How to approach this question

Recognize that quotas are hard limits enforced by GCP. The only way to get more resources than the quota allows is to request an increase.

Full Answer

C.Submit a quota increase request for N2 CPUs in `us-central1` via the Google Cloud Console immediately.✓ Correct
Submit a quota increase request for N2 CPUs in `us-central1` via the Google Cloud Console immediately.
Google Cloud enforces quotas on resource usage for a variety of reasons, including protecting users from unexpected spikes in usage. When planning for a known massive traffic event, capacity planning must include checking and requesting quota increases well in advance. Quota increases are requested directly through the Cloud Console.

Common mistakes

Assuming you can just turn off quotas (D). Quotas are controlled by Google. Changing instance types (A) is a risky workaround that might hit a different quota limit anyway.
