Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 727

Which network devices secure API platforms?

Answer options

• A. content switches
• B. web application firewalls
• C. next-generation intrusion detection systems
• D. Layer 3 transit network devices

Correct answer: B

Explanation

Web application firewalls (WAFs) are specifically designed to protect web applications, including APIs, by filtering and monitoring HTTP traffic. In contrast, content switches manage traffic but do not focus on security, next-generation intrusion detection systems primarily detect threats rather than prevent them, and Layer 3 transit network devices deal with packet routing without inherent security functions.
