CompTIA Cloud+ (CV0-004) — Question 90

A cloud engineer is provisioning a new application that requires access to the organization’s public cloud resources. Which of the following is the best way for the cloud engineer to authenticate the application?

Answer options

• A. API key
• B. Cookie
• C. MFA
• D. Username and password

Correct answer: A

Explanation

Using an API key is the best choice for authenticating applications that access public cloud resources, as it provides a secure and straightforward means of access without user interaction. Cookies are typically used for session management in web applications, while MFA and username/password combinations are more suited for user authentication rather than application authentication.
