What is the role of a Certificate Authority (CA) in certificate management for network access?

To encrypt all network traffic between the client and the access point

To assign IP addresses to clients

To store user passwords for authentication

To issue and sign digital certificates that verify the identity of clients and servers

How does Juniper Mist integrate with a RADIUS server for authentication?

Mist replaces the RADIUS server and performs all authentication locally

Mist acts as a RADIUS proxy, forwarding authentication requests to the external server

Mist requires the RADIUS server to be on the same subnet as the access points

Mist uses the RADIUS server only for accounting, not authentication

What is the primary purpose of Juniper Mist Access Assurance?

To provide a cloud-based platform for managing and monitoring network performance

To enforce network access control policies for users and devices connecting to the network

To provide a secure tunnel for remote users to access the corporate network

To automate the configuration of Juniper switches and routers

A user reports they cannot connect to the Wi-Fi. Which first step would you take to troubleshoot using Juniper Mist?

Check the Access Assurance logs for authentication failures

Disable the user's account in the identity provider

A government agency is deploying 802.1X with Juniper Mist Access Assurance. They have a private CA and want to use EAP-TLS for all clients. During a pilot, a test client fails to authenticate. The Mist logs show a TLS handshake failure. What is the most likely cause of this failure?

The client's certificate is not trusted by the RADIUS server because the CA certificate is not installed on the server.

The client's supplicant is not configured with the correct username and password.

The client is using the wrong EAP method, such as PEAP instead of EAP-TLS.

The Mist access policy is configured to use MAC Authentication Bypass instead of 802.1X.
