   A company is setting up MPSK for a temporary event. They want to create a passphrase that will be used by all attendees. They plan to delete this passphrase after the event. In the Juniper Mist portal, where would the administrator go to create and later delete this passphrase?

   • BNavigate to the Organization's Users page and add a new user with the passphrase as their password.
   • CNavigate to the Site's SSIDs page and create a new SSID with the passphrase.
   • DNavigate to the WLAN's MPSK settings and add a new entry with a name and passphrase. To delete, remove the entry from the same page.

   An administrator has configured MPSK on a WLAN. A user reports they cannot authenticate. The administrator checks the Mist portal and sees the client is failing authentication. The MPSK passphrase was recently changed. What is the most likely reason for the authentication failure?

   • AThe Access Policy for the MPSK name is misconfigured, blocking the user's VLAN.
   • BThe WLAN's encryption method was changed from WPA2 to WPA3, which is incompatible with MPSK.
   • CThe AP is not broadcasting the SSID because MPSK is enabled.
   • DThe client device is still using the old passphrase. The administrator should verify the client has updated to the new passphrase.
