350-701 Practice Question: Migrating a web application to AWS and wants to…
A company is migrating a web application to AWS and wants to protect against DDoS attacks at the application layer. Which Cisco security solution should they deploy?
⚠ Common exam trap
It's easy for candidates to confuse a network-layer DDoS mitigation solution (like Firepower NGFW or Umbrella) with an application-layer WAF, failing to recognize that only a WAF provides the deep HTTP inspection and rate-limiting needed for Layer 7 attacks.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cisco WAF (Web Application Firewall)
A Web Application Firewall (WAF) is the correct solution because it specifically inspects and filters HTTP/HTTPS traffic at the application layer (Layer 7), protecting against DDoS attacks such as HTTP floods, SQL injection, and cross-site scripting. Cisco WAF (often delivered via Cisco Secure Web Application or integrated with AWS WAF) can rate-limit requests, block malicious payloads, and enforce positive security models to mitigate application-layer DDoS. This directly addresses the requirement to protect a web application migrating to AWS against Layer 7 attacks.
