Which Juniper Mist dashboard feature uses the ROAMINGOF element?

The ROAMINGOF element is a specific filter within the Marvis Query Language (MQL). MQL is a structured search tool that allows administrators to perform precise queries against the Mist cloud's data. Using the ROAMINGOF filter, an administrator can find clients that have roamed from a particular Access Point (AP), BSSID, or radio. This is a powerful tool for troubleshooting specific client roaming behaviors and performance issues.

A. The Conversational Assistant uses natural language processing to translate user questions into MQL, but the user does not directly use elements like ROAMINGOF.

C. Marvis Minis are dashboard widgets that visualize network data; they are a presentation layer, not the query language itself.

D. Wireless SLEs are high-level performance metrics. MQL and its elements are used to investigate the root cause of a poor SLE, not define it.

- Juniper Mist Documentation, "Marvis Query Language." This document provides a list of available MQL filters, including ROAMINGOF, and describes its function for querying client roaming events from a specific source.

- Juniper Networks, "Marvis Conversational Assistant," Datasheet. Page 2, Section "Marvis Query Language," explains that MQL provides "the ability to query the Mist platform for insights into the network and user experiences," with examples of specific query elements.
