A developer is troubleshooting a local Java application that is failing to authenticate with Amazon DynamoDB. The developer has configured a profile in the shared credentials file (~/.aws/credentials) and also set the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables in the terminal session.
In which of the following locations will the default credential provider chain look to resolve credentials, and which has higher precedence? (Select TWO.)
- Environment variables are evaluated first and have higher precedence than the shared credentials file.Cevap
- The shared credentials file is evaluated after environment variables are checked.Cevap
- CHardcoded credentials in the application's source code are evaluated as the final fallback in the default credential provider chain.
- DAWS Systems Manager Parameter Store is checked before the shared credentials file.
- EThe IAM trust policy of the developer's local workstation is evaluated first.
Cevap
The default credential provider chain evaluates environment variables first, and then evaluates the shared credentials file.
The Default Credentials Provider Chain in the AWS SDK evaluates credential sources in a specific order of precedence. Environment variables (such as AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY) are evaluated first, while the shared credentials file (~/.aws/credentials) is checked later in the chain.
