A company is troubleshooting 802.1X on a Mist-managed AP. A user's smartphone can authenticate, but a laptop fails with 'EAP-TLS certificate validation failed' in the Mist logs. The laptop is configured with the correct user certificate. What is the most likely cause?

The laptop does not trust the CA that issued the RADIUS server's certificate

The smartphone is using a different EAP method than the laptop

The AP is not configured with the correct RADIUS shared secret

The RADIUS server is not configured with the laptop's user certificate

A manufacturing plant is deploying 802.1X on Mist-managed switches to secure its OT network. The plant manager wants to ensure that if the RADIUS server becomes unreachable, the switches do not block all traffic on the access ports. What should the network engineer configure in the Mist switch template?

Disable 802.1X on the access ports and rely on MAC authentication bypass

Configure the RADIUS server with a longer timeout value

Set the authentication failure and server timeout actions to 'allow' on the access ports

Use a local fallback authentication method on the switch

A multi-national company uses Mist Access Assurance for 802.1X. They need to enforce different access policies based on the user's group (e.g., engineering vs. finance) and the device's compliance status (e.g., antivirus up-to-date). The RADIUS server is Mist Access Assurance. What is the most efficient way to achieve this?

Use a single policy that grants access based on user group only, ignoring device compliance

Configure Access Assurance policies that match on both user group and device compliance attributes

Create separate SSIDs for each user group and device compliance state

Configure the RADIUS server to return the same VLAN for all users and rely on the firewall for segmentation

A company is using Mist Access Assurance for 802.1X. They want to ensure that only devices that are enrolled in their MDM can access the corporate SSID. How can this be achieved in Mist Access Assurance?

Configure an Access Assurance policy that checks the device's MDM compliance status

Use a pre-shared key (PSK) for the SSID

Use MAC address filtering on the AP

Configure the RADIUS server to reject all authentication requests
