A batch processing job requires high CPU performance and is not memory-intensive. Which EC2 instance family is most appropriate for this workload?

Accelerated Computing (P family)

A company wants to increase the availability of its application by running it in multiple Availability Zones. What is the primary cost trade-off of this approach?

Reduced storage costs because data is replicated

Lower compute costs due to better utilization

No additional cost because AWS provides free inter-AZ traffic

Higher data transfer costs between Availability Zones

A company has IoT devices that generate data. To reduce latency and data transfer costs, where should the data be processed?

At the edge, close to the devices

In a VPC in a single Availability Zone

A company wants to reduce compute costs by paying only for the compute time consumed, without managing servers. Which AWS compute service is serverless and charges only for the duration of code execution?

Amazon ECS with EC2 launch type

A global IoT company collects sensor data from millions of devices. The devices need to respond to commands with minimal latency, and the company wants to reduce data transfer costs to the AWS Region. Which strategy should they implement?

Use EC2 instances in multiple Regions

Send all data to a central AWS Region for processing

Use AWS Outposts in each device location

Use AWS Lambda@Edge for processing at edge locations

Task 4.2: Design Cost-Optimized Compute Solutions SAA-C03 Practice Questions (Page 4)

Part of the Design Cost-Optimized Architectures domain, which makes up ~31% of our current practice bank. AWS does not publish an official question count, but from its 130-minute exam (~50–85 total, ~16–26 in this domain), expect 4–7 from this objective — we provide 30 practice questions to prepare you well beyond it.
