A user reports that their laptop connects to the corporate WLAN but cannot reach the internet. Other users on the same AP are working fine. The Mist dashboard shows the client is associated with an AP and has a valid IP address. What should the administrator check next in Mist to isolate the issue?

The client's authentication logs for 802.1X failures

The AP's RF health and interference levels

The client's assigned VLAN and firewall policy

The client's signal strength and retry rate

A hotel wants to offer a free basic Wi-Fi service to all guests and a premium tier with higher bandwidth for paying guests. Both tiers should use the same SSID. The hotel uses a captive portal for guest access. How can the administrator differentiate the service levels in Juniper Mist?

Use dynamic PSK to provide different keys for basic and premium guests

Configure two separate SSIDs, one for basic and one for premium

Create two WLANs with the same SSID but different VLANs and apply different QoS policies

Use a single WLAN with a captive portal that assigns different VLANs based on the user's selection

A hospital has a WLAN using 802.1X with PEAP-MSCHAPv2. Recently, some Windows laptops fail to connect, while others work fine. The Mist dashboard shows authentication failures with the error 'EAP-MSCHAPv2 authentication failed'. The administrator checks the RADIUS logs and sees that the failures occur only for users whose passwords contain special characters. What is the most likely cause and solution?

The WLAN is configured for WPA3-Enterprise, which does not support PEAP-MSCHAPv2; switch to WPA2-Enterprise

The affected laptops have outdated wireless drivers; update the drivers

The RADIUS server is rejecting passwords with special characters due to an encoding mismatch; configure the RADIUS server to use UTF-8 encoding

The client certificates are expired; renew them for the affected laptops

A hospital is deploying a new guest WLAN for visitors. They require that each visitor receives a unique pre-shared key that is automatically rotated and can be revoked individually without affecting other guests. The SSID must support the latest security standard on capable devices while remaining compatible with older devices. Which configuration should the administrator use?

WPA3-Enterprise with 802.1X and a RADIUS server using per-user certificates

WPA2-PSK with a single shared passphrase and a long key rotation interval

WPA2/WPA3 mixed mode with Mist dynamic PSK (DPSK)

WPA3-SAE with a single passphrase and opportunistic wireless encryption
