Question 1 of 30

A global online retail platform, hosted on Google Cloud, experiences an unprecedented 300% surge in customer traffic due to a viral marketing campaign. This surge is projected to last for an indeterminate period, potentially weeks. The platform must remain fully operational, with no degradation in user experience, and must also adhere to stringent financial regulations requiring demonstrable cost efficiency and transparent resource expenditure. The existing architecture utilizes Compute Engine instances and Cloud SQL. What strategic approach should the Cloud Architect prioritize to manage this situation effectively, balancing immediate operational demands with long-term compliance and cost-effectiveness?

Implement a dynamic autoscaling strategy across Compute Engine instances and GKE, coupled with proactive cost monitoring using Cloud Monitoring and Budget Alerts, and explore the use of preemptible VMs for non-critical background tasks to optimize expenditure while maintaining service continuity.
Immediately scale up all Compute Engine instances to the largest available machine types and provision additional Cloud SQL read replicas to absorb the increased load, without immediate focus on cost optimization due to the critical nature of service availability.
Halt all non-essential background processing and scheduled jobs, and manually adjust Compute Engine instance sizes based on daily performance reports, while deferring any cost optimization initiatives until the traffic surge subsides.
Rely solely on the default autoscaling configurations for Compute Engine and Cloud SQL, assuming Google Cloud's managed services will inherently handle the cost and performance fluctuations without further intervention.
