An AWS user is trying to launch an Amazon Elastic Compute Cloud (Amazon EC2) instance in a given region. What is the region-specific constraint that the Amazon Machine Image (AMI) must meet so that it can be used for this Amazon Elastic Compute Cloud (Amazon EC2) instance?
You can use an Amazon Machine Image (AMI) from a different region, but it degrades the performance of the Amazon EC2 instance
An Amazon Machine Image (AMI) is a global entity, so the region is not applicable
You should use an Amazon Machine Image (AMI) from the same region, as it improves the performance of the Amazon EC2 instance
You must use an Amazon Machine Image (AMI) from the same region as that of the Amazon EC2 instance. The region of the Amazon Machine Image (AMI) has no bearing on the performance of the Amazon EC2 instance
You must use an Amazon Machine Image (AMI) from the same region as that of the Amazon EC2 instance. The region of the Amazon Machine Image (AMI) has no bearing on the performance of the Amazon EC2 instance
An Amazon Machine Image (AMI) provides the information required to launch an instance. The Amazon Machine Image (AMI) must be in the same region as that of the Amazon EC2 instance to be launched.
A startup runs its proprietary application on docker containers. As a Cloud Practitioner, which AWS service would you recommend so that the startup can run containers and still have access to the underlying servers?
Amazon Elastic Container Service (Amazon ECS)

Amazon Elastic File System (Amazon EFS)
Instance Store
Amazon Elastic Block Store (Amazon EBS)
Amazon Simple Storage Service (Amazon S3)
Instance Store
Instance store is ideal for the temporary block-level storage of information that changes frequently, such as buffers, caches, scratch data, and other temporary content, or for data that is replicated across a fleet of instances, such as a load-balanced pool of web servers.
Which of the following AWS services offer block-level storage? (Select two)
Amazon Elastic Container Service (Amazon ECS)
Amazon Elastic File System (Amazon EFS)
Instance Store
Amazon Simple Storage Service (Amazon S3)
