QUESTION NO: 1
An application running on Amazon EC2 instances must access objects within an Amaon S3 busket that are encrypted using server-side encryption using AWS KMS encryption keys (SSE-KMS).

Which combination of steps will grant the application access? (Select TWO.)
A. Create a Systems Manager parameter that exposes the KMS key to the EC2 instances.
B. Write a key policy that enables IAM policies to grant access to the key.
C. Grant access to the key in the S3 bucket's ACL

E. Write an S3 bucket policy that grants the bucket access to the key.
Answer: B,D
Explanation
https://aws.amazon.com/premiumsupport/knowledge-center/decrypt-kms-encrypted-objects-s3/
IAM role needs access to the keys to decrypt the object and key policies must allow role access to the key. Key policies are the primary way to control access to customer master keys (CMKs) in AWS KMS.
You need the permission to decrypt the AWS KMS key. When a user sends a GET request, Amazon S3 checks if the AWS Identity and Access Management (IAM) user or role that sent the request is authorized to decrypt the key associated with the object. If the IAM user or role belongs to the same
AWS account as the key, then the permission to decrypt must be granted on the AWS KMS key's policy.
