TheROAMINGOF elementis part of theMarvis Query Language (MQL), which is the structured query syntax used byMarvis, Juniper’sVirtual Network Assistant (VNA).
According to theJuniper Mist Marvis and MQL Technical Reference, Marvis Query Language provides advanced data query and automation capabilities that go beyond the conversational interface. It allows administrators to directly extract analytical insights, run network diagnostics, and perform queries related touser experience metricsandService Level Expectations (SLEs).
The documentation specifies:
“MQL is the analytical engine of Marvis that uses elements such as ROAMINGOF, CONNECTIVITYOF, and PERFORMANCEOF to query Mist data and retrieve SLE metrics, performance trends, and device events.”
TheROAMINGOFelement specifically relates to theWireless Roaming SLEcategory, enabling Marvis to evaluate client roaming performance across access points, identify failed transitions, and correlate signal quality or capacity-related issues.
While theConversational Assistant (A)uses natural language queries, it translates them internally intoMQLcommands.Marvis Minis (C)runs synthetic tests, andWireless SLE (D)displays performance metrics but does not directly use MQL syntax elements.
Thus, the correct answer isB. Marvis Query Language.
