A retailer is migrating on-premises workloads to AWS and needs to automatically handle seasonal traffic spikes cost-effectively. Which AWS features will help accomplish this? (Choose two.)

The pay-as-you-go pricing model is correct because it means the retailer only pays for the resources consumed, avoiding upfront costs and allowing them to scale resources up and down with demand without incurring costs for idle capacity. Auto Scaling policies are correct because they automatically adjust the number of compute resources (like EC2 instances) in response to demand changes, ensuring performance during traffic spikes and scaling down during lulls to save costs. Cross-Region workload deployment is incorrect as it focuses on disaster recovery and latency, not directly on cost-effective handling of seasonal spikes. Built-in AWS CloudTrail audit capabilities are for logging API calls and auditing, not for managing traffic or costs. Centralized logging helps with operational insights but doesn't directly address scaling or cost-effectiveness for traffic spikes.
