NEW QUESTION # 134
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?
Answer: C
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.

NEW QUESTION # 135
In the context of Juniper Mist, which two statements describe a bad user minute? (Choose two.)
Answer: C,D
Explanation:
A bad user minute normalizes a user's negative network experience into a measurable metric.
It is calculated as the number of affected users multiplied by the number of minutes they are affected, giving a quantifiable measure of user impact.
NEW QUESTION # 136
Your company hosts its own enterprise-wide monitoring solution. You want to receive events from Juniper Mist. How would you accomplish this task?
Answer: D
Explanation:
To integrate Juniper Mist events with an external monitoring solution, you configure a webhook, which allows Mist to push real-time event notifications directly to your system.
NEW QUESTION # 137
What are two ways to claim an Access Point with Juniper Mist? (Choose two.)
Answer: A,D
Explanation:
From Juniper's official guide:
"You'll need either a claim code or an activation code to claim an AP. With either, you can claim an AP by using one of the following methods:
* Mist AI Mobile App
* A Web browser
You can claim either a single AP using a claim code or multiple APs using an activation code. You can use any of these methods to claim an AP:
* To claim a single AP, use the claim/QR code located on the rear of the AP.
* To claim multiple APs, you'll need to use an activation code. When you purchase multiple APs, we provide you with an activation code along with your PO information." From the Mist documentation:
"APs can be claimed to any organization by using either the activation code, claim code or QR code.
Activation Code: Whenever you order APs, our Sales Operations team will send you an activation code which can be used for claiming the APs and subscriptions as per the order. ...
AP Claim Code: You can individually claim APs to your organization by navigating to Organization > Inventory > Claim APs and entering in the claim code found on the back of each AP.
AP QR Code: Using our Mist AI mobile app you can scan the QR code printed on the back of our APs to claim APs to your organization." Summary:
The Juniper Mist platform allows you to claim an Access Point using:
* Activation code (provided for bulk purchases, via PO)
* Claim code (unique per AP, on the rear label)
* QR code (scanned with the Mist AI mobile app, also encoded as the claim code) These extracts are direct from Juniper's own documentation and confirm the methods for AP onboarding in the Mist platform.
