What is one key difference between Marvis Insight and Marvis Action?
- A . Insights are used for firmware upgrades
- B . Actions can make changes; Insights only explain issues
- C . Insights trigger SNMP traps; Actions only log events
- D . Actions are available only for 6 GHz networks
B
Explanation:
Marvis Insights help identify and explain network problems; Marvis Actions go a step further by recommending or executing fixes.
A university deploys Mist Wi-Fi across multiple buildings. All users connect to a single SSID called “CampusWiFi.” However, students should only have internet access, while faculty should access internal systems like printers and servers.
What is the **best way** to implement this using Mist?
- A . Create two SSIDs with different VLAN tags
- B . Assign WxLAN roles based on RADIUS authentication and enforce role-based VLAN and policy controls
- C . Set SLE scores differently for students and faculty
- D . Use MAC address filtering for faculty and students
B
Explanation:
Mist’s WxLAN allows assigning roles based on RADIUS identity. Both students and faculty can connect to the same SSID, but access different network resources based on their assigned roles and VLANs.
What is the primary role of a Captive Portal operating in "Redirect-Only" mode in Mist?
- A . Handles authentication within the Mist cloud
- B . Provides MAC address whitelisting for IoT devices
- C . Delivers RADIUS attribute enforcement
- D . Redirects clients to an external site without performing authentication
D
Explanation:
In Redirect-Only mode, Mist simply redirects clients to an external URL. It doesn’t perform authentication or policy enforcement ― this is handled by the external server.
Which pair of configuration objects must be cloned when copying a full site to a new tenant? Choose two.
- A . WLAN objects
- B . RF profiles
- C . WxLAN policy tags
- D . Organization‑level webhook secrets
- E . REST API tokens
A, B
Explanation:
WLANs and RF profiles are site‑specific and need duplication; WxLAN tags live at org level, webhooks and tokens don’t copy with sites.
What type of failure is Marvis most likely to report if a device is associated with an AP but never receives an IP address?
- A . Authentication failure
- B . DNS resolution error
- C . DHCP failure
- D . VLAN misalignment
C
Explanation:
If a client is associated but does not obtain an IP address, Marvis will detect and report a DHCP failure, possibly due to DHCP server issues or bad options.
When troubleshooting a coverage‑hole SLE breach, which Marvis insights and RF metrics are most telling? Choose two.
- A . Client RSSI distribution heat‑map
- B . AP neighbour‑list completeness percentage
- C . Client EAP failure count
- D . Wi‑Fi location accuracy deviation
- E . DHCP discover/reply time delta
A, B
Explanation:
Low RSSI and sparse neighbour lists confirm RF holes; EAP, location deviation, and DHCP timings are secondary.
A Mist administrator receives a notification stating: “Users in the East Wing are experiencing high DHCP failure rates.” This type of AI-generated message is an example of:
- A . SLE alert
- B . SNMP trap
- C . Marvis Insight
- D . AP health log
C
Explanation:
Marvis Insight interprets event patterns and surfaces actionable issues, such as DHCP failures in specific areas, with context and suggestions.
Which steps are mandatory to enable Proximity Tracing using vBLE while also surfacing insights in Marvis NLP? Choose three.
- A . Upload accurate floor plans with scale and orientation
- B . Enable “Virtual BLE” under Site → Radio Settings
- C . Create a REST API key with “BLE Analytics” scope
- D . License the site with User‑Engagement or Asset‑Visibility SKU
- E . Add a WxLAN policy allowing multicast DNS
A, B, D
Explanation:
Trilateration needs floor plans and vBLE turned on; an LBS license is required. API keys are optional for automation, and mDNS isn’t mandatory for BLE telemetry.
A company enables 160 MHz channels on all 5 GHz APs to maximize speed. However, users report unstable performance in open office areas.
What is the **most likely technical reason** for this problem?
- A . Wide channels overlapping and increasing interference
- B . Clients only supporting 2.4 GHz band
- C . Excessive collision detection by CSMA/CD
- D . Channel width too narrow for high data rates
A
Explanation:
160 MHz channels are wide and can easily overlap with other nearby APs using the same frequency. This leads to increased interference and instability in shared environments. A narrower width (40/80 MHz) may perform better.
A technician is deploying Mist APs in a new office site. After plugging the APs into a PoE-enabled switch and verifying they receive DHCP addresses, the APs are not broadcasting any SSIDs.
What is the **most likely reason** for this behavior?
- A . The APs need static IPs to function with the Mist cloud
- B . The APs must be registered and assigned a configuration template in Mist Cloud
- C . Marvis AI must first run an RF scan before enabling broadcast
- D . The APs require CLI access to enable SSIDs manually
B
Explanation:
In Mist, APs must be registered to an organization/site and have a configuration template applied before broadcasting SSIDs. DHCP and PoE are necessary, but cloud configuration is essential to complete the setup.
