CompTIA Cloud+ (CV0-004) — Question 20

A cloud engineer needs to integrate a new payment processor with an existing e-commerce website. Which of the following technologies is the best fit for this integration?

Answer options

• A. RPC over SSL
• B. Transactional SQL
• C. REST API over HTTPS
• D. Secure web socket

Correct answer: C

Explanation

The correct answer is C, REST API over HTTPS, as it allows for easy and secure communication between the e-commerce website and the payment processor. Options A and D, while secure, are not as commonly used for payment processing integration. Option B, Transactional SQL, is not suitable for this type of integration as it pertains to database transactions rather than web service communication.
