A. B. C. D.Answer - B.
The AWS Documentation mentions the following:
AWS Auto Scaling enables you to configure automatic scaling for the scalable AWS resources for your application in a matter of minutes.
AWS Auto Scaling uses the Auto Scaling and Application Auto Scaling services to configure scaling policies for your scalable AWS resources.
For more information on AWS Autoscaling, please refer to the below URL:
https://docs.aws.amazon.com/autoscaling/plans/userguide/what-is-aws-auto-scaling.htmlThe AWS service that allows you to increase the number of resources based on the demand of the application or users is AWS Autoscaling, which is option B.
AWS Autoscaling allows you to automatically adjust the capacity of your EC2 instances based on the demand of your application or users. Autoscaling can help you maintain the availability and performance of your applications by automatically scaling your resources up or down based on the changing needs of your applications.
With AWS Autoscaling, you can create scaling policies that define when and how your instances should be scaled. For example, you can create a policy that scales your instances up when CPU utilization reaches a certain threshold or when there is an increase in traffic to your application. Similarly, you can create a policy that scales your instances down when the demand for your application decreases.
In addition to scaling EC2 instances, AWS Autoscaling can also be used to scale other AWS resources, such as Elastic Load Balancers and Amazon RDS instances.
AWS EC2 (option A) is a web service that provides resizable compute capacity in the cloud. While EC2 instances can be manually scaled up or down, Autoscaling provides a way to do this automatically based on demand.
AWS ELB (option C) is a service that automatically distributes incoming application traffic across multiple targets, such as EC2 instances. While ELB can help improve the availability and performance of your applications, it does not provide the automatic scaling capabilities of Autoscaling.
AWS Inspector (option D) is a security assessment service that helps you identify potential security issues in your applications and resources. It does not provide any automatic scaling capabilities.
