Answer: BD

Explanation:

The error message in the image indicates that the cluster creation failed due to reaching the maximum retries for provisioning cluster nodes.

Here are two possible scenarios that could lead to this issue:

Insufficient Permissions (Answer B):

If the AWS user or role used to create the cluster does not have sufficient permissions, it can result in failures during the provisioning process. Proper IAM policies must be attached to ensure that the necessary actions can be performed, such as launching instances, creating VPCs, or managing networking components.

AWS Quota Exceeded/Instance Limit Exceeded (Answer D):

AWS imposes quotas and limits on the number of instances and other resources that can be created within an account. If these quotas are exceeded, new instances cannot be provisioned, causing the cluster creation to fail. This can be resolved by requesting a quota increase from AWS.
