You are an AWS Solutions Architect. A company owns a large number of batch processing workloads in a local data center and plans to migrate these jobs in AWS Batch. The company needs your help to decide which provisioning model should be chosen in AWS Batch jobs. Which of the following situations would you use for AWS Fargate in AWS Batch? (Select TWO)

Answer options:

A.When a batch job needs access to particular instance configurations, including processors and GPUs.
B.When a batch job needs to be started fast at the initial scale-out of work.
C.When a batch job needs to use a compute environment based on a custom AMI and the instance type must be A1.
D.When users do not want to provision or scale clusters of virtual machines to run containers for AWS Batch jobs.
E.When a batch job needs the instance type to be C5 with multiple vCPUs.

Correct Answers: B and D
Option A is incorrect. Because, for this option, the EC2 instance is more suitable as users can choose the instance configurations.
Option B is CORRECT. Because with Fargate, jobs can start faster at the initial scale-out of work as users do not need to wait for EC2 instances to launch.
Option C is incorrect. Because the EC2 instance is more suitable as users need to customize the AMI and instance type. Users cannot do this with Fargate.
Option D is CORRECT. Because Fargate manages the servers and clusters of EC2 instances for AWS Batch jobs. Users do not need to worry about the details of compute resources.
Option E is incorrect. Because with Fargate, users cannot select instance types or the minimum number of vCPUs.
