One batch job is CPU-intensive and another processes a large amount of local data.
Match each workload with an EC2 category.
Choose TWO appropriate mappings.
Compute optimized instances target CPU-intensive workloads, while storage optimized instances target high local-storage I/O workloads.
Detailed explanation
Compute optimized instances are designed for workloads that need high CPU performance.

Instance types differ in CPU, memory, storage, and network characteristics.

The smallest size may not meet performance requirements; the choice must fit the workload.

Foundation review
Requirement fit
The instance category should follow the dominant workload characteristic, not just the smallest price.
Capacity sizing
Category and size are separate decisions: first choose the resource profile, then the required capacity.
