1. Question 511 · 712 in bank

   Which Amazon EC2 Reserved Instances term commitment will give users the MOST cost savings?

   • A1 year
   • B2 years
   • C3 years
   • D5 years

   Show answer

   Answer: C

   Explanation

   Amazon EC2 Reserved Instances offer cost savings in exchange for a commitment to use EC2 capacity over a set term, with the 3-year term providing the highest savings compared to the 1-year option. AWS does not offer a 5-year term for Reserved Instances, so 3 years is the longest available and the most cost-effective option. Summary: A 3-year Reserved Instance term provides the greatest cost savings, making option C the correct answer.

3. Question 513 · 712 in bank

   A company runs Amazon EC2 instances in a research lab. The instances run for 3 hours each week and cannot be interrupted. What is the MOST cost-effective instance purchasing option to meet these requirements?

   • ACompute Savings Plan
   • BOn-Demand Instances
   • CConvertible Reserved Instances
   • DSpot Instances

   Show answer

   Answer: B

   Explanation

   Per ChatGPT Compute Savings Plans are not suitable for instances that run for only 3 hours a week without interruption. Compute Savings Plans provide discounts for consistent usage of EC2 instances in exchange for a commitment to a specific amount of compute usage (measured in dollars per hour) over a 1- or 3-year term. They are designed for workloads with predictable and sustained usage, not for sporadic or short-duration instances like those running only 3 hours per week. Therefore, Compute Savings Plans would not be the most cost-effective option for this scenario.

   Show answer

   Answer: C

   Explanation

7. Question 517 · 712 in bank

   A company has a test AWS environment. A company is planning on testing an application within AWS. The application testing can be interrupted and does not need to run continuously. Which Amazon EC2 purchasing option will meet these requirements MOST cost-effectively?

   • AOn-Demand Instances
   • BDedicated Instances
   • CSpot Instances
   • DReserved Instances

   Show answer

   Answer: C

   Explanation

   On-Demand Instances: On-Demand Instances are suitable for workloads that need flexibility and are short-term or unpredictable. However, they are priced higher than other options. Dedicated Instances: Dedicated Instances run on hardware dedicated to a single customer account but are priced higher than On-Demand Instances. They may not be the most cost-effective for interruptible workloads. Spot Instances: Spot Instances allow you to bid for unused EC2 capacity at potentially lower costs. They are suitable for interruptible workloads where you can tolerate potential interruptions. However, they can be terminated with short notice if the capacity is needed by On-Demand or Reserved Instances. Reserved Instances: Reserved Instances provide a capacity reservation and offer cost savings over On-Demand pricing for a commitment of 1 or 3 years. They are more suitable for steady-state workloads with predictable usage.
