Which VLAN configuration method enables Mist to assign different VLANs to users on the same SSID?
- A . VLAN pooling with random assignment
- B . Static VLAN mapping via port groups
- C . WxLAN identity-based VLAN assignment
- D . LACP-based VLAN trunking
C
Explanation:
With WxLAN, Mist can dynamically assign VLANs based on user identity, device type, or authentication method ― all while using a single SSID.
A healthcare provider is deploying Mist APs in a hospital. Due to strict data protection regulations, all patient-related traffic must stay within the building and never touch the cloud.
Which Mist component is required in this design?
- A . Mist Edge for local traffic breakout and compliance
- B . Marvis AI with SLE metrics enabled
- C . Webhook-based DNS redirection
- D . Mist-hosted Captive Portal
A
Explanation:
Mist Edge enables on-premises traffic forwarding while still using cloud-managed configuration. It ensures compliance with data protection rules by keeping sensitive traffic local.
A Mist administrator observes that several APs in a conference room are showing increased retry rates and degraded SLE scores. Users report that Wi-Fi becomes slow during events.
What Mist feature is designed to help **automatically resolve** this kind of channel interference issue?
- A . Marvis Actions
- B . Manual SSID rebroadcasting
- C . Fixed transmit power profiles
- D . Roaming priority settings
A
Explanation:
Marvis Actions can automatically perform network optimizations like adjusting channel plans and transmit power to reduce interference and improve client experience based on detected SLE degradation or event patterns.
During a roaming event, a client device moves from one AP to another. The connection drops briefly and then resumes. A packet trace shows the client sent a **probe request**, then performed **authentication** and **association** again.
What IEEE 802.11 standard could help minimize this disruption?
- A . 802.11a
- B . 802.11ac
- C . 802.11r
- D . 802.11b
C
Explanation:
To satisfy a data‑sovereignty policy, a customer wants all Wi‑Fi analytics to be processed locally, yet still consume Marvis NLP from the cloud.
Which architecture satisfies both? Choose two.
- A . Deploy Mist Edge in “Analytics” mode for on‑prem processing
- B . Configure the APs to send syslog directly to a local collector
- C . Enable the “Cloud anonymisation” toggle in org privacy settings
- D . Use REST API /local_msp/logs to upload summaries nightly
- E . Keep Marvis Pro license active at organization level
A, E
Explanation:
Edge in analytics mode keeps raw data on‑prem while Marvis Pro (cloud) interprets meta‑data; this honours sovereignty yet enables NLP insights. Syslog and manual REST uploads are unrelated, and anonymisation alone doesn’t localise data.
Which of the following is a recommended AP spacing for accurate vBLE triangulation in indoor deployments?
- A . 10 meters or less
- B . 20 meters or more
- C . Exact center of each room
- D . Random to reduce interference
A
Explanation:
For accurate directional triangulation using Mist vBLE, it is recommended to space APs ≤10 meters apart.
Which two client roaming enhancements require 802.11k/v and are exposed in Mist dashboard metrics? Choose two.
- A . Neighbour‑list reporting
- B . BSS transition management (BTM)
- C . Fast BSS Transition (11r)
- D . Opportunistic Wireless Encryption (OWE)
- E . Target Wake Time (TWT)
A, B
Explanation:
11k supplies neighbour lists, 11v enables BTM; both appear in roaming stats. 11r, OWE, TWT are other amendments.
A healthcare clinic requires that all IoT medical devices (e.g., monitors, scanners) connect securely without user interaction and be placed in VLAN 30. These devices don’t support 802.1X.
What is the most appropriate way to allow access using Mist?
- A . Create a hidden SSID with WPA3-Enterprise
- B . Use OWE encryption and dynamic VLAN mapping
- C . Use sponsor-based guest portal login for all devices
- D . Assign a WxLAN “IoT” role based on MAC address and map to VLAN 30
D
Explanation:
Mist allows MAC-based WxLAN role assignment, ideal for IoT devices that cannot perform 802.1X. The role can assign VLAN 30 automatically for isolation and policy enforcement.
During proactive troubleshooting, which Marvis components interact with SLE “Roaming” metrics and event insights to suggest optimizations? Choose two.
- A . Marvis Languages natural‑language parser
- B . Marvis Actions engine
- C . Marvis Minis synthetic roaming tests
- D . Webhook alerts for “Excessive 802.11 retries”
- E . Network arbitration threshold defined in WLAN object
B, C
Explanation:
Marvis Minis gather synthetic data (e.g., roaming times), feeding the Actions engine that correlates with SLEs and event insights to propose fixes. The NLP parser is only an interface; webhooks just forward alerts; arbitration thresholds are a WLAN‑level RF setting, not a Marvis component.
What is the function of the WxLAN feature in Mist?
- A . Assigns VLANs dynamically based on user/device identity
- B . Encrypts data traffic using WPA3 only
- C . Automatically tunnels guest traffic to the cloud
- D . Extends wired VLANs into remote data centers
A
Explanation:
WxLAN allows Mist to apply role-based access policies and assign VLANs dynamically based on identity (e.g., employee, guest, printer), even on the same SSID.
