Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 73

Why is end-to-end encryption deployed when exposing sensitive data through APIs?

Answer options

• A. Data transfers are untraceable from source to destination.
• B. Data cannot be read or modified other than by the true source and destination.
• C. Server-side encryption enables the destination to control data protection.
• D. Traffic is encrypted and decrypted at every hop in the network path.

Correct answer: B

Explanation

End-to-end encryption ensures that only the intended sender and receiver can read or modify the data, which protects it from interception. Option A is incorrect because end-to-end encryption does not make transfers untraceable; option C is wrong as server-side encryption does not guarantee protection for the data in transit; option D is inaccurate since it implies multiple decryption points which contradict the concept of end-to-end encryption.
