NEW QUESTION # 25
Your organization currently uses Access Assurance for 802.1X authentication of wireless users using user certificates. All users are currently placed in the same VLAN after authentication.
There are multiple VLANs at your sites.
In this scenario, how would you configure Access Assurance to make the network more secure?

  • A. Configure user authentication using EAP-TTLS and assign WxLAN roles based on AD user group.
  • B. Configure MAC Authentication Bypass (MAB) and assign WxLAN roles based on groups of MAC addresses.
  • C. Configure host (machine) authentication using EAP-TLS and assign WxLAN roles based on AD user group.
  • D. Configure user authentication using EAP-TLS and assign WxLAN roles based on AD user group.

Answer: D

Explanation:
Juniper Mist Access Assuranceprovidescloud-based network access control (NAC)by integratingRADIUS
,identity-based policy enforcement, andWxLAN role-based segmentation. It allows administrators to assign users and devices to specific VLANs or network segments dynamically based on authentication attributes, thereby improving bothsecurityandpolicy granularity.
According to theJuniper Mist Access Assurance Configuration Guide, to enhance network security in a multi-VLAN environment, you should:
"Use EAP-TLS (certificate-based authentication) for secure user identification, and dynamically assign WxLAN roles or VLANs based on Active Directory (AD) group membership." Here's whyDis correct:
* EAP-TLSensuresmutual authenticationbetween client and RADIUS server using digital certificates
- preventing credential theft or spoofing.
* Integrating withActive Directoryallowsrole-based access control (RBAC), enabling dynamic VLAN or WxLAN assignment. This ensures users from different groups (e.g., staff, contractors, guests) are automatically segmented into appropriate network zones.
Option breakdown:
* A (MAB): Used for non-802.1X devices (e.g., printers), less secure for user authentication.
* B (EAP-TTLS): Username/password-based and less secure than certificate-based EAP-TLS.
* C (Host authentication): Verifies devices only, not user identity-insufficient for user-level control.
Therefore, the most secure and scalable configuration is:
#D. Configure user authentication using EAP-TLS and assign WxLAN roles based on AD user group.
