A. B. C. D.

Answer - C.

The AWS Documentation mentions the following.

Access keys consist of an access key ID (for example, AKIAIOSFODNN7EXAMPLE) and a secret access key (for example, wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY)

You use access keys to sign programmatic requests that you make to AWS if you use the AWS SDKs, REST, or Query API operations.

Option A is incorrect because it works with APIs or SDK.

You need to use Access Key ID and Secret Access Key.

Options B and D are incorrect because SSL/TLS certificates or X.509 certificates are used to secure network communications.

They are not used to access AWS resources.

To make successful calls to AWS services using REST API, you would need Access Keys. Access Keys consist of an Access Key ID and a Secret Access Key. These are long-term credentials used to identify and authenticate your application with AWS services.

Access Keys provide programmatic access to AWS services through the AWS API. They can be used to make programmatic calls to AWS services using tools such as the AWS SDKs and REST APIs.

The Access Key ID is used to identify your application or user account when making API calls to AWS services. The Secret Access Key is used to sign API requests to AWS services, which is used to verify that the request comes from an authorized source.

It is important to keep the Secret Access Key confidential and never share it with anyone or include it in any code or configuration files that are shared or stored in a public place.

User name and password are not typically used for authentication to AWS services through REST API. SSL certificates and X.509 certificates may be used for secure communication, but they are not required for basic authentication with AWS services through REST API.
