An admin wants Marvis to suggest improvements but doesn’t want any changes made automatically.
Which execution mode should they use?
- A . Manual Review
- B . Auto Execution
- C . Read-Only Mode
- D . Bulk Push
A
Explanation:
Manual Review mode lets Marvis suggest actions, but requires the admin to manually approve them before implementation.
A hospital deploys Mist APs with vBLE to track wheelchairs across multiple floors. However, the location accuracy is inconsistent, especially near elevators and glass-walled corridors.
What is the most likely cause of this issue?
- A . The BLE tags are using outdated firmware
- B . The APs are misconfigured with incorrect SSIDs
- C . The APs are spaced too closely (<3 meters)
- D . RF reflections from glass and metal are disrupting signal triangulation
D
Explanation:
Reflective surfaces like **glass walls and metal structures** can cause signal distortion or multipath effects, reducing the precision of vBLE-based triangulation.
What deployment best practice improves the accuracy of Mist’s indoor location services?
- A . Mount APs 2.5C4 meters high facing downward
- B . Use only 2.4 GHz radios for lower interference
- C . Disable directional BLE antennas
- D . Place APs in walls instead of ceilings
A
Explanation:
Mounting APs at the recommended height (2.5C4 meters) facing downward ensures optimal signal coverage and BLE directionality.
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.
A helpdesk technician receives a call from a user who says, “I can see the Wi-Fi network, but I can’t connect.” The admin types the user’s MAC address into Marvis. The response shows: “Association successful → Authentication failed → PSK mismatch.” What should the technician do next?
- A . Ask the user to verify their Wi-Fi password
- B . Restart the AP
- C . Reset the DHCP server
- D . Adjust the transmit power on the AP
A
Explanation:
Marvis has already identified a **PSK mismatch** in the authentication stage. This indicates the user entered the wrong Wi-Fi password. Re-entering the correct password resolves the issue.
A school uses a single SSID for all users. Faculty should have access to printers and internal resources, while students should only have web access.
What Mist feature enables this?
- A . WxLAN role-based policy with dynamic VLAN assignment
- B . WPA3-Personal with MAC filtering
- C . SSID band steering and SLE scoring
- D . DNS blacklisting per client
A
Explanation:
WxLAN allows dynamic role-based policy enforcement. The same SSID can assign different VLANs and permissions depending on RADIUS roles or MACs.
A company wants to track how long visitors spend near specific product displays and whether they return later.
Which Mist feature would support this use case?
- A . Indoor navigation
- B . Engagement analytics with heatmaps and dwell time
- C . Turn-by-turn pathing
- D . Proximity tracing
B
Explanation:
Heatmaps and dwell time metrics are part of Mist Premium Analytics, used to analyze visitor behavior and optimize engagement strategies.
What does Mist’s API-first architecture enable you to do?
- A . Automate the deployment and management of sites via RESTful APIs
- B . Update firmware on APs using TFTP
- C . Monitor AP health via SNMP traps only
- D . Restrict users based on MAC address filtering
A
Explanation:
Mist’s API-first approach allows you to automate tasks such as creating sites, registering APs, applying templates, pulling performance data, and integrating with IT systems.
An IT administrator wants to trigger alerts when high-value medical carts leave the ICU area.
Which feature should they configure?
- A . Path Replay
- B . Indoor Navigation
- C . SDK-based Engagement
- D . Asset Geofencing
D
Explanation:
Geofencing in Mist LBS allows defining virtual boundaries (zones), triggering alerts when tracked assets like medical carts leave the defined area.
The IT team at a hospital receives an alert via Microsoft Teams that a critical AP in the ICU has gone offline. They want to ensure they only get **important alerts** without being overwhelmed by minor notifications.
What Mist feature helps them control this?
- A . SNMP Polling
- B . Alert Suppression and Severity Settings
- C . Manual Log Filtering
- D . Historical Client Comparison
B
Explanation:
Mist lets you assign severity levels (e.g., Critical, Major, Minor) and apply alert suppression rules to avoid notification spam. You can also send high-priority alerts to platforms like Teams or ServiceNow via webhook.
