Network Load BalancerApplication Load BalancerClassic Load BalancerAll of the above
Network Load Balancer operates at the transport layer (Layer 4) of the OSI model.

Which AWS service can be used to automate the process of requesting Spot Instances and to maintain the number of Spot Instances in a fleet?

AWS Auto ScalingAWS Elastic BeanstalkAmazon EC2 Auto ScalingAWS Lambda
Amazon EC2 Auto Scaling helps you ensure that you have the correct number of Amazon EC2 instances available to handle the load for your application. You create collections of EC2 instances, called Auto Scaling groups.

Can you use your own domain name instead of the Elastic Beanstalk environment URL?

Yes, by configuring a CNAME record in your DNS providerNo, you can only use the Elastic Beanstalk environment URLYes, by modifying the Elastic Beanstalk configuration filesNone of the above
You can use your own domain name instead of the Elastic Beanstalk environment URL by configuring a CNAME record in your DNS provider. The CNAME record should point to the Elastic Beanstalk environment URL.

What is the main purpose of AWS Auto Scaling?

To increase storage capacityTo improve data transfer speedTo maintain application availability and performanceTo provide machine learning capabilities
The main purpose of AWS Auto Scaling is to ensure that your applications have the right amount of capacity to handle the current traffic demand. It does this by automatically increasing or decreasing capacity as needed.

Can AWS Config monitor resources that are located outside of AWS?

Yes, AWS Config can monitor any resource that is connected to the internetNo, AWS Config can only monitor AWS resourcesYes, but only if the resources are located in a VPCYes, but only if the resources are managed by AWS Systems Manager
AWS Config can only monitor resources that are located within AWS. It cannot monitor resources that are located outside of AWS.
