The AI VALIDATED status update means that the issue was opened and Marvis confirms it has been closed.

According to the Marvis Virtual Network Assistant Datasheet1, the AI-VALIDATED status update means that the issue was opened and Marvis confirms it has been closed. This status indicates that Marvis has verified that the issue is no longer present and the root cause has been resolved.

As part of the Throughput SLE in the Mist UI, the Coverage classifier indicates the signal strength of the client.

InJuniper Networks Mist AI Wireless, controlling client connection quality is a critical part of maintaining high Service Level Expectations (SLEs). One of the most effective ways to ensure good user experience is by enforcing aminimum acceptable RSSI (Received Signal Strength Indication)threshold for client devices. This functionality is implemented usingwireless traffic filteringat the WLAN level.

Wireless traffic filtering allows administrators to defineminimum and maximum RSSI thresholdsthat determine whether a client is permitted to associate or remain connected to an SSID. If a client’s RSSI falls below the configured minimum threshold, the AP can deny association requests or deauthenticate the client. This prevents low-signal or “sticky” clients from connecting at poor signal levels, which would otherwise result in excessive retries, low data rates, increased airtime consumption, and degraded performance for all users.

Mist applies these controls intelligently and surfaces their impact through AI-driven analytics. When low-RSSI clients are filtered, Mist can correlate improvements in throughput, latency, and roaming behavior directly to RF health and client quality metrics. This aligns with Mist best practices, which emphasize proactive client quality enforcement rather than reactive troubleshooting.

The incorrect options are explained as follows:

WLAN forwardingdetermines how traffic is bridged, tunneled, or NATed and has no impact on RSSI enforcement.

Geofencingis used for location-based services and RTLS use cases, not RF signal quality control.

WLAN rate limitrestricts bandwidth usage per client or SSID but does not evaluate or enforce signal strength requirements.

Therefore, the correct feature required to set an acceptable minimum RSSI for client devices iswireless traffic filtering, which directly controls association behavior based on signal quality and helps maintain optimal wireless performance.

Syslog is a protocol that can be used to forward event messages from Mist to an external log collector.

According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, syslog is a feature that enables forwarding event messages from Mist to an external log collector. Syslog messages can be sent over UDP or TCP protocols.

According to the Create a Mist Account and Organization - Mist document1, two fields that are required when creating a new site are:

Site name, which is a unique identifier for the site within the organization.

Time zone, which is used to display the correct time for events and reports related to the site.

 According to the Cisco Catalyst 9800 Series Wireless Controller Software Configuration Guide1, RF templates are assigned to sites, which are logical groupings of devices based on physical location or other criteria. RF templates allow you to configure RF parameters such as channel width, transmit power, and data rates for multiple devices at once.

InJuniper Networks Mist AI Wireless, Juniper prescribes atop-down, structured troubleshooting methodologywhen using Service-Level Expectations (SLEs). This approach ensures that engineers identify systemic issues before drilling into individual client problems, preventing misdiagnosis and wasted effort.

The correct troubleshooting order is:

Organization → Site → SLE → Client

Organization of interestTroubleshooting always begins at the organization level. This provides a global view of overall health, license status, widespread outages, and configuration changes that may impact multiple sites. Organization-level visibility helps determine whether the issue is localized or systemic.

Site of interestAfter confirming the organization is healthy, the next step is narrowing the scope to the affected site. Site-level views expose infrastructure issues such as WAN problems, DHCP outages, AP connectivity issues, or RF-wide anomalies that affect many users simultaneously.

SLE of interestOnce scoped to the site, administrators identify the specific degraded SLE (for example, Time to Connect, Coverage, Capacity, or Throughput). Each SLE includes classifiers that pinpoint the likely root cause, such as DHCP, DNS, authentication, or RF interference.

Client of interestOnly after isolating the failing SLE should troubleshooting move to the individual client level. Client views provide detailed timelines, event history, and packet-level insights to confirm whether the issue is isolated or a symptom of a broader problem.

The other answer choices are incorrect because they start with either the SLE or client, which risks overlooking organization-wide or site-wide conditions. Juniper’s recommended workflow ensures efficient, accurate fault isolation and aligns with how Mist AI correlates telemetry and events.

Therefore, the correct answer isA. Organization of interest, site of interest, SLE of interest, client of interest.

According to the Mist documentation1, WLANs are wireless networks that can be configured with different settings such as SSID, security, encryption, authentication, etc. WLANs can be created and managed at different levels of hierarchy in the Mist cloud.

The site group level allows you to create and apply WLANs to a group of sites that share common characteristics or requirements2. This helps you to simplify and standardize your WLAN configuration across multiple sites.

The site level allows you to create and manage WLANs for a specific site that may have unique needs or preferences1. This gives you more flexibility and granularity for your WLAN configuration at each site.
