18. What role does reserved instance pricing play in cost management?

It reduces costs by committing to long-term usage at discounted rates

It guarantees zero downtime for all applications

It eliminates the need for monitoring

It increases storage capacity automatically

19. When investigating a sudden billing increase, what should you check first?

Review recent infrastructure changes and deployments

Restart all cloud instances

Increase security group restrictions

Migrate to a different cloud provider

20. Which metric is most useful for identifying cost anomalies in a multi-cloud environment?

Cost per transaction

CPU utilization rate

Memory allocation size

Network latency
