Practice Test 4 | AWS Certified Cloud Practitioner | CLF-C01 | Dumps | Mock Test
An organization has started a new project to create memes based on user comments and uploaded images. As this new project is started on a pilot basis and is not pursued rigorously, cost efficiency is emphasized and not the uptime and processing time.
Given these priorities, which EC2 Instance should be preferred?
A. On-Demand Instance
B. Spot Instance
C. Dedicated Instances
D. Scheduled Reserved Instances
Answer: B
- Option A is INCORRECT. On-Demand Instances are costlier than spot instances.
- Option B is CORRECT. Spot instances are the most cost-efficient option. Please note interruptions are stated to be not an issue.
- Option C is INCORRECT. Dedicated Instances are instances that are dedicated to a single user. Dedicated instances are not suitable for these types of scenarios.
- Option D is INCORRECT. Scheduled Reserved Instances will not be preferable over spot instances in this scenario because interruptions are stated to be not an issue. Nothing in this scenario states about long term requirement. Scheduled Reserved Instances requires long term commitment.
