AWS Certified Cloud Practitioner (CLF-C02) — Question 116

A company is running a workload in the AWS Cloud.
Which AWS best practice ensures the MOST cost-effective architecture for the workload?

Answer options

• A. Loose coupling
• B. Rightsizing
• C. Caching
• D. Redundancy

Correct answer: B

Explanation

Rightsizing is the practice of adjusting the size of your AWS resources to match the workload's actual needs, which helps minimize costs. Loose coupling, caching, and redundancy are important architectural principles but do not primarily focus on cost efficiency like rightsizing does.
