When comparing the total cost of ownership (TCO) of an on-premises data center versus a cloud deployment, which of the following should be included in the TCO calculation?

Hardware purchase costs, operational expenses, and cloud service fees

Only the initial hardware purchase price

A cloud architect notices that the monthly bill for a web application has increased significantly. The application serves users globally, and the increase coincides with a new feature that allows users to upload large media files. Which cost driver is most likely responsible for the increase?

Data egress charges from users downloading the media files

Storage costs for the uploaded files

Networking costs for internal traffic between services

Compute costs for processing the uploads

A research organization runs a high-performance computing (HPC) workload on AWS that is used for two weeks every quarter. The workload is fault-tolerant: individual compute nodes can be lost and the job will re-run the failed portion. The organization has a strict budget and wants to minimize cost. However, the workload also has a hard deadline — it must complete within the two-week window. Which combination of pricing models should the architect recommend?

A mix of Spot Instances for the majority of nodes and On-Demand for a small core set

Reserved Instances for the full year

All On-Demand instances to guarantee completion

A startup is designing a new customer-facing API on AWS. The workload is expected to have unpredictable traffic with occasional spikes. The architecture must minimize cost during low-traffic periods while keeping response latency under 200 ms. Which compute approach best balances these requirements?

EC2 Auto Scaling with a minimum of 2 and maximum of 10 instances

AWS Lambda with a provisioned concurrency of 1

A single large EC2 instance running the API and a database

A fleet of always-on EC2 instances sized for peak load

A multinational company has a single AWS account hosting workloads for three business units: Marketing, Engineering, and Finance. The cloud team needs to generate a monthly report showing exactly how much each business unit spends on EC2, S3, and data transfer. Currently, all resources are untagged. What should the architect do first to enable this reporting?

Create separate IAM users for each business unit and review their CloudTrail logs

Use AWS Budgets to set a single monthly budget for the entire account

Create a tagging strategy with a mandatory 'BusinessUnit' tag and apply it to all existing and new resources

Enable AWS Cost Explorer and use its built-in service-level filters
