Reliability — GCP PCA Practice Question 46

How to approach this question

Identify the three proactive steps for massive scale: offload traffic (CDN), ensure GCP allows the scale (Quotas), and prove it works (Load Testing).

Full Answer

Preparing for a massive, predictable traffic spike requires proactive capacity planning. 1) Cloud CDN offloads traffic from the backend, protecting the compute layer. 2) GCP has hard quotas on resources (like CPUs); if you don't request an increase, your autoscaler will fail to spin up new VMs when you hit the limit. 3) Load testing is the only way to prove that your database, application code, and autoscaling policies will actually function under 10x load.

Common mistakes

Forgetting about GCP Quotas (Option C). Many architectures fail during spikes not because of bad design, but because they hit a default GCP quota limit.

A global streaming service is planning for a major live event that is expected to generate 10x their normal traffic. They use Compute Engine, Cloud SQL, and Cloud Load Balancing. To ensure capacity and reliability during the event, which THREE actions should they take in advance? (Select THREE)
