CLF-C02 Question #11: Real Exam Question with Answer & Explanation

Question

A company wants to run its workload on Amazon EC2 instances for more than 1 year. This workload will run continuously. Which option offers a discounted hourly rate compared to the hourly rate of On-Demand Instances?

Options

• AAWS Graviton processor
• BDedicated Hosts
• CEC2 Instance Savings Plans
• DAmazon EC2 Auto Scaling instances

Explanation

EC2 Instance Savings Plans are the right choice because they offer a discounted hourly rate (up to 72% off On-Demand pricing) in exchange for a commitment to a consistent amount of compute usage over a 1 or 3-year term - making them ideal for workloads running continuously for more than one year.

Why the others are wrong:

• AWS Graviton processor (A) is a type of processor architecture that can offer better price-performance, but it is not a pricing model that directly provides a discounted hourly rate compared to On-Demand.
• Dedicated Hosts (B) provide physical servers dedicated to your use (often for compliance/licensing reasons), but they typically cost more than standard On-Demand instances, not less.
• EC2 Auto Scaling instances (D) automatically adjust capacity based on demand, but Auto Scaling is a scaling feature, not a pricing model - it uses On-Demand (or Spot) pricing by default.

Memory Tip: Think of Savings Plans = Savings through commitment. Whenever you see a question about long-term, continuous workloads needing a discounted rate, think "commitment = savings" - Savings Plans (EC2 Instance or Compute) are AWS's go-to answer for predictable discounts on steady workloads.
