For which of the following scenarios should a Solutions Architect consider using ElasticBeanStalk? (Choose TWO.)

Answer options:

A.A Java web application using Amazon Linux EC2 instances
B.An Enterprise Data Warehouse
C.Configuring AWS resources using Chef
D.A worker environment with an SQS queue and an Auto Scaling group
E.A management task run once on nightly basis

Answer – A and D
AWS Documentation clearly mentions that the Elastic Beanstalk component can create Web Server environments and Worker environments.
The following diagram illustrates an example of Elastic Beanstalk architecture for a web server environment tier and shows how the components in that type of environment tier work together. 
https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features-managing-env-tiers.html
For more information on AWS Elastic beanstalk Web server environments, please visit the URL https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/concepts-webserver.html
Option B is incorrect. Elastcibeanstalk is used to deploy and manage the applications on AWS. It`s not used to store the data. https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/Welcome.html.
For more information on AWS Elastic beanstalk Worker environments, please visit the following URL: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/concepts-worker.html
Option C is incorrect. OpsWorks is more suitable when Chef is used to configure AWS resources.
Option D is correct. The worker environments in Elastic Beanstalk include an Auto Scaling group and an SQS queue. This option is suitable.
Option E is incorrect. When you launch an Elastic Beanstalk environment, you first choose an environment tier. The environment tier that you choose determines whether Elastic Beanstalk provisions resources to support an application that handles HTTP requests or an application that pulls tasks from a queue. An application that serves HTTP requests runs in a web server environment. An environment that pulls tasks from an Amazon Simple Queue Service queue runs in a worker environment.
Further, when you create an environment, Elastic Beanstalk provisions the resources required to run your application. AWS resources created for an environment include one elastic load balancer (ELB in the diagram), an Auto Scaling group, and one or more Amazon EC2 instances.
So, these resources must run the application 24/7, not for only at night or day.
