Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 162

How do end-to-end encryption principles apply to APIs?

Answer options

• A. The owners of the service are prevented from accessing data that is being transferred.
• B. Sensitive information is protected against backdoor attacks.
• C. The API data is protected against man-in-the-middle attacks.
• D. Both endpoints that are using the API resources are hardened against hacking.

Correct answer: C

Explanation

The correct answer is C because end-to-end encryption effectively ensures that data remains confidential and is not accessible to anyone who might intercept it during transmission, which includes protection against man-in-the-middle attacks. Option A is incorrect because service owners can still access data unless specific measures are taken. Option B, while relevant to security, does not directly pertain to the principles of end-to-end encryption. Option D is also misleading as hardening endpoints does not directly relate to the encryption of data in transit.
