AWS Certified SAP on AWS – Specialty (PAS-C01) — Question 81

A company uses SAP S/4HANA as its ERP solution. The company is using AWS Backint Agent for SAP HANA (AWS Backint agent) for backups. Although the configuration is correct for AWS Backint agent, the backups are falling with the following error.

NoCredentialProviders: no valid providers in chain.

What could be the reason for this error?

Answer options

• A. AWS Systems Manager Agent is not installed on the Amazon EC2 instance.
• B. No IAM role is attached to the Amazon EC2 instance.
• C. AWS Backint agent binaries are owned by a non-root user.
• D. AWS Backint agent is connecting to Amazon S3 with VPC endpoints.

Correct answer: B

Explanation

The correct answer is B because if there is no IAM role attached to the Amazon EC2 instance, the AWS Backint agent cannot access the necessary permissions to perform backups, leading to the credential error. Option A is incorrect as the installation of the AWS Systems Manager Agent is not related to credential issues. Option C is not relevant since ownership of the binaries does not affect the IAM permissions required. Option D does not address the credential provider issue, as VPC endpoints do not inherently relate to providing IAM credentials.
