350-701 Practice Question: Deploying a cloud-based web application and wants…

A company is deploying a cloud-based web application and wants to protect against OWASP Top 10 attacks. Which THREE security controls should they implement? (Select three.)

⚠ Common exam trap

Cisco often tests the distinction between application-layer controls (input validation, WAF, rate limiting) and infrastructure-layer controls (DLP, hypervisor segmentation), leading candidates to mistakenly select DLP or hypervisor segmentation as protections against OWASP Top 10 attacks.

Answer choices

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

Input validation

Input validation (A) is correct because it is a fundamental security control that sanitizes and validates user-supplied data before processing, directly mitigating injection attacks (e.g., SQLi, XSS) listed in the OWASP Top 10. By enforcing whitelist-based validation on the cloud-based web application, it prevents malformed or malicious input from reaching the application logic, which is critical for cloud environments where the application is exposed to the internet.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Input validation

    Why this is correct

    Prevents injection attacks.

  • Rate limiting

    Why this is correct

    Prevents brute force and DDoS.

  • Data loss prevention (DLP)

    Why it's wrong here

    Not directly related to OWASP.

  • Network segmentation at the hypervisor level

    Why it's wrong here

    Network security, not OWASP-specific.

  • Web application firewall (WAF)

    Why this is correct

    Filters common web attacks.
