CND Application And Data Protection Practice Question

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
✓
IIS Request Filtering with rules to deny double-encoding and path traversal sequences ('..')
URL Authorization and Request Filtering in IIS inspect incoming request URLs for suspicious patterns, double-escaping, and path traversal sequences like '..', blocking them before execution.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
HTTP Compression Schema module
Why it's wrong here
HTTP compression optimizes bandwidth usage for response payloads, unrelated to security filtering.
- ✓
IIS Request Filtering with rules to deny double-encoding and path traversal sequences ('..')
Why this is correct
IIS Request Filtering inspects requests for path traversal sequences and double-encoded characters and blocks them.
- ✗
IP Address and Domain Restrictions module
Why it's wrong here
This module restricts access based on client IP addresses or domain names, not request URL content.
- ✗
Windows Authentication Provider with Kerberos constraints
Why it's wrong here
Authentication providers handle user identity verification, not URL payload inspection.
