Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
ESC1: Enrollee supplies subject and template permits client authentication for low-privileged users
Why this is correct
ESC1 allows requesting certificates for arbitrary users.
- ✓
ESC4: Low-privileged users have Write permissions (Modify/WriteDACL) over the certificate template
Why this is correct
ESC4 allows modifying template settings to introduce vulnerabilities like ESC1.
- ✗
ESC10: Strict certificate mapping and strong SID binding enforced
Why it's wrong here
ESC10 represents hardening settings (KB5014754) that mitigate certificate mapping bypasses.
- ✗
LDAP signing enforced across all domain controllers
Why it's wrong here
Enforcing LDAP signing is a hardening measure, not a vulnerability.
- ✓
ESC8: HTTP-based enrollment endpoints permitting NTLM relay
Why this is correct
ESC8 leverages web enrollment endpoints for NTLM relay attacks.
