Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 207

Where must the data be encrypted to ensure end-to-end encryption when using an API?

Answer options

• A. on the server that stores the data
• B. on the end device after a request is received
• C. on the device that consumes the API
• D. on the source device before transmission

Correct answer: D

Explanation

The correct answer is D because end-to-end encryption requires that data is encrypted at the source before it is transmitted, ensuring that only the intended recipient can decrypt it. Options A, B, and C do not provide the necessary level of security for end-to-end encryption, as they involve encryption occurring after data has already left the source device.
