Cloud Use Cases — Quiz

Test your understanding of cloud use cases with 5 practice questions.

Practice Questions

Question 1

A global web application requires that 95\% of user requests from North America, Europe, and Asia experience p95 latency under 50~ms. Which cloud architecture best meets this requirement while minimizing operational overhead?

Question 2

A data engineering team needs to run complex Apache Spark ETL jobs on 10~TB of data every hour with predictable performance and custom configuration. Which cloud service is most appropriate?

Question 3

A deep learning training workflow requires 1{,}000 GPU-hours. On-demand GPU instances cost \4 per GPU-hour. Spot GPU instances cost \$1.2 per GPU-hour but have a 20\% interruption rate, each interruption incurring a 30-minute restart overhead on average. If the team runs 80\% of the workload on Spot and the rest on On-demand, what is the expected total compute cost?

Question 4

An industrial IoT deployment must continue performing data filtering and decision-making at the edge when connectivity to the cloud is intermittent. Which solution pattern is most suitable?

Question 5

A biomedical research group runs hourly batch analytics on 50~TB of genomics data using complex Python-based transformations. They require custom libraries and configuration. Which service should they choose?
