Oracle Cloud Infrastructure 2023 Architect Associate — Question 18

You are using a custom application with third-party APIs to manage the application and data hosted in an Oracle Cloud Infrastructure (OCI) tenancy. Although your third-party APIs do not support OCI's signature-based authentication, you want them to communicate with OCI resources.
Which authentication option should you use to ensure this?

Answer options

• A. Auth Tokens
• B. API Signing Key
• C. SSH Key Pair with 2048-bit algorithm
• D. OCI Username and Password

Correct answer: A

Explanation

Auth Tokens are suitable for scenarios where third-party APIs do not support signature-based authentication, allowing secure communication with OCI resources. The API Signing Key requires signature-based authentication, which is not supported by the third-party APIs. An SSH Key Pair is primarily used for secure shell access, not API interaction, while OCI Username and Password are less secure and not ideal for programmatic access.
