AWS Certified Security - Specialty

  • Topic 1 Question 136

    A company has an application that needs to get objects from an Amazon S3 bucket. The application runs on Amazon EC2 instances.

    All the objects in the S3 bucket are encrypted with an AWS Key Management Service (AWS KMS) customer managed key. The resources in the VPC do not have access to the internet and use a gateway VPC endpoint to access Amazon S3.

    The company discovers that the application is unable to get objects from the S3 bucket.

    Which factors could cause this issue?
