This CS0-003 practice question tests your understanding of vulnerability management. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: dAST tools need valid credentials for authenticated scanning.. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A DAST scan cannot reach authenticated pages of a web application and reports only public content findings. What should be configured? For stakeholder management, Which documentation or approval is required to keep the programme defensible?
Disable all application authentication
Why wrong: This would change the application and create risk.
Treat absence of findings as proof of security
Why wrong: Unreached pages were not tested.
Authenticated scanning with a test account and session handling
DAST needs valid authentication and session management to test protected functionality.
Reduce the scan to only the landing page
Why wrong: That further limits coverage.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Authenticated scanning with a test account and session handling
DAST scanners cannot access authenticated pages without valid session credentials. Configuring authenticated scanning with a test account and proper session handling (e.g., via cookies, tokens, or form-based login) allows the scanner to crawl and test behind the login wall, ensuring coverage of all application states. This is the standard remediation for the described limitation.

That further limits coverage.
Common exam traps
The trap here is that candidates may assume any authentication bypass or disabling security is acceptable, when the correct approach is to provide the scanner with legitimate credentials and session management to test authenticated areas safely.
Detailed technical explanation
Authenticated DAST scanning typically works by recording a login sequence (e.g., via a proxy or macro) that the scanner replays to obtain and maintain a session token (e.g., JSESSIONID or Bearer token). The scanner then includes this token in subsequent requests to traverse protected resources. In real-world scenarios, session timeouts, CSRF tokens, or multi-factor authentication can break the scan, requiring careful configuration of session handling rules or use of a dedicated test account with extended session expiry.
Key takeaway
DAST tools need valid credentials for authenticated scanning.
Real-world example
A security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
