Practice Test 2 | AWS Certified Cloud Practitioner | CLF-C01 | Dumps | Mock Test
A large Oil & gas company is planning to deploy a high-volume application on multiple Amazon EC2 instances. Which of the following can help to reduce operational expenses?
A. Deploy Amazon EC2 instance with Auto-scaling
B. Deploy Amazon EC2 instance in multiple AZ’s
C. Deploy Amazon EC2 instance with Amazon instance store-backed AMI
D. Deploy Amazon EC2 instance with Cluster placement group
Correct Answer: A
Using Amazon EC2 Auto-Scaling helps to match the workload on the application with the optimum number of the Amazon EC2 instance. Due to this, during low load on application, Amazon EC2 instances are terminated which reduces operational cost.
- Option B is incorrect as deploying an Amazon EC2 instance in a multiple AZ might enhance application availability but will not reduce operational expenses.
- Option C is incorrect as deploying an Amazon EC2 instance with Amazon instance store-backed AMI incur charges for Amazon EC2 instance usage & storing AMI in Amazon S3. There will be no impact on operational expense using this AMI type.
- Option D is incorrect as deploying an Amazon EC2 instance in a cluster placement group will help to have low latency between instances but will not reduce operational expenses.
