What is the primary purpose of 802.1X in a Juniper Mist-managed network?

To automatically assign IP addresses to devices on the network

To provide port-based network access control, allowing or denying a device's access to the network based on authentication

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

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

A company is deploying 802.1X on Mist-managed switches. They have two RADIUS servers: one primary and one secondary. The primary server is temporarily down for maintenance. The engineer notices that clients are still authenticating successfully. What is the most likely reason?

The switch is using a local fallback authentication method

The clients are using cached credentials from a previous session

The switch is configured with a secondary RADIUS server and is failing over to it

The switch is not enforcing 802.1X on the ports

When troubleshooting a failed 802.1X authentication, which common issue would you look for in the Mist logs?

The client's IP address is not in the correct subnet

The switch's management VLAN is misconfigured

The access point is not broadcasting the SSID

A hospital is deploying 802.1X for its nursing staff using Mist-managed APs. The security team mandates that authentication must be certificate-based with mutual authentication, and they want to avoid deploying a separate CA infrastructure. Which EAP method should the network engineer select in the Mist Access Assurance policy?

EAP-TTLS-PAP with the Mist cloud acting as the certificate authority

EAP-FAST with the Mist cloud acting as the certificate authority

EAP-TLS with the Mist cloud acting as the certificate authority

PEAP-MSCHAPv2 with the Mist cloud acting as the certificate authority

A university is deploying 802.1X for its student Wi-Fi. The IT team is configuring the supplicant on student laptops. Which statement correctly describes the role of the supplicant in the 802.1X process?

The supplicant validates the client's credentials against the RADIUS server

The supplicant controls the port state based on the authentication result

The supplicant initiates authentication by sending EAPOL-start and responds to EAP requests from the authenticator

The supplicant forwards EAP frames between the client and the RADIUS server
