Question 5
Domain 1: Cloud ConceptsA company is reviewing its cloud spending and notices several workloads consistently use only a small fraction of their allocated compute and memory resources. Which action best demonstrates rightsizing?
Correct answer: B
Explanation
Rightsizing means choosing cloud resources that match actual workload requirements so you avoid paying for more capacity than you need. — 05-AWS_Core_Services.md
Why each option is right or wrong
A. Increase resource allocations across all workloads to prepare for future growth
Rightsizing matches resources to current workload needs, not blanket overprovisioning for possible future demand.
B. Adjust resource selections so each workload more closely matches its actual usage patterns
The source defines rightsizing as understanding and applying the concept of matching resources to workload needs. Because these workloads use only a small fraction of allocated compute and memory, selecting resources that better fit their actual usage is the rightsizing action in this scenario.
C. Move every workload to the largest available instance family for performance consistency
Rightsizing focuses on aligning capacity with workload requirements, not standardizing on the largest instance type.
D. Keep existing resource allocations unchanged to avoid any operational adjustments
Rightsizing requires evaluating whether allocated resources fit workload demand; leaving overallocated resources unchanged does not do that.
