Mist AI Wireless, Specialist (JNCIS-MistAI-Wireless) JN0-452 Practice Test 10

Question 90

A hospital's Successful Connects SLE falls following a RADIUS configuration update, while AP RSSI remains strong. The selected operator action is: Drill into Authorization failures and compare the affected EAP events to the configuration change. Which postchange finding most directly validates the action?

  1. A test managed client completes enterprise authentication after the actual RADIUS issue is corrected
  2. The original threshold is met through measured client improvement rather than altered reporting
  3. The affected access point receives adequate supported power and its intended radios remain enabled
  4. The narrowed timeline exposes the failed stage during the affected users' session

Explanation

Correct Answer

A:

A test managed client completes enterprise authentication after the actual RADIUS issue is corrected directly tests the proposed corrective action: Drill into Authorization failures and compare the affected EAP events to the configuration change. SLE troubleshooting links the selected failed classifier to real client and upstream dependency evidence before changing infrastructure.

Incorrect Answers

B:

That observation would confirm another situation: An engineer changes SLE thresholds to make a failing department green without repairing its persistent connection faults. Here the selected action should produce: A test managed client completes enterprise authentication after the actual RADIUS issue is corrected.

C:

This check instead concerns a separate case: A hospital's AP Health SLE flags low power while every AP looks physically mounted and connected. Here the selected action should produce: A test managed client completes enterprise authentication after the actual RADIUS issue is corrected.

D:

That evidence would establish success in a different scenario: A campus WLAN quality score is poor but the operator studies the previous month rather than the reported afternoon outage. Here the selected action should produce: A test managed client completes enterprise authentication after the actual RADIUS issue is corrected.

Question 91

A classroom receives a corporate WLAN configuration object but its AP profile never advertises the selected SSID. The recommended remediation is: Bind the WLAN to the intended AP/site deployment target and verify actual beaconing. What evidence most clearly distinguishes success from a partial fix?

  1. The surviving permitted WLANs retain correct access and the stale policy reference is absent
  2. A capable 6 GHz client completes compliant security negotiation while legacy 5 GHz service remains separate
  3. A client scan detects the SSID on the correct APs and sees the approved security mode
  4. At both locations clients authenticate to the same SSID and receive correct site-local addresses

Explanation

Correct Answer

C:

A client scan detects the SSID on the correct APs and sees the approved security mode directly tests the proposed corrective action: Bind the WLAN to the intended AP/site deployment target and verify actual beaconing. WLAN objects must be scoped to the intended radios, sites, networks and associated security and portal dependencies.

Incorrect Answers

A:

This check instead concerns a separate case: A consultant deletes a WLAN object without checking that an access-policy rule still references its identifier. Here the selected action should produce: A client scan detects the SSID on the correct APs and sees the approved security mode.

B:

That evidence would establish success in a different scenario: A retailer expects 6 GHz SSIDs to accept an old WPA2-only WLAN security profile copied from 5 GHz. Here the selected action should produce: A client scan detects the SSID on the correct APs and sees the approved security mode.

D:

That observation would confirm another situation: A campus needs the same staff SSID at two sites with distinct local IP subnets and different uplink mappings. Here the selected action should produce: A client scan detects the SSID on the correct APs and sees the approved security mode.

Question 92

A university purchases Wireless Assurance for only half of its AP inventory but expects complete advanced analytics across every building. The change request proposes: Reconcile AP inventory and assigned subscription entitlements before expanding the service promise. Which outcome should the site engineer expect after the repair?

  1. The transferred AP has the approved organization owner and its required Wireless Assurance license works
  2. Subscription reports identify the uncovered APs and required monitored devices show valid entitlements
  3. An attempted template edit outside the operator's approved scope fails and is auditable
  4. The customer gets separate identities, device inventory and configuration boundaries

Explanation

Correct Answer

B:

Subscription reports identify the uncovered APs and required monitored devices show valid entitlements directly tests the proposed corrective action: Reconcile AP inventory and assigned subscription entitlements before expanding the service promise. Mist organization scope, least-privilege identities and active subscriptions must match the responsible tenant and deployed services.

Incorrect Answers

A:

That evidence would establish success in a different scenario: A network team changes device ownership during an acquisition without checking whether licensed WLAN features remain available under the receiving organization. Here the selected action should produce: Subscription reports identify the uncovered APs and required monitored devices show valid entitlements.

C:

That observation would confirm another situation: A global WLAN uses site-specific administrators yet a template editor is inadvertently allowed to change every international location. Here the selected action should produce: Subscription reports identify the uncovered APs and required monitored devices show valid entitlements.

D:

This check instead concerns a separate case: An engineer confuses adding a new Mist site with creating a legally separate organization for a new external customer. Here the selected action should produce: Subscription reports identify the uncovered APs and required monitored devices show valid entitlements.

Question 93

A retail center assumes that the AP with the strongest RSSI identifies an exact shopper coordinate even though the device is moving among several floors. The site engineer plans to: Use supported Wi-Fi location methods and calibrated multi-AP floor context rather than a single signal observation. What observation would justify marking this case resolved?

  1. A receiving analyst sees only approved devices and events for the designated tenant
  2. An occupancy sample more closely matches the permitted indoor zone without counting neighboring networks
  3. The live view distinguishes recently seen devices from historical observations after clients leave
  4. A representative walk trace follows the correct floor and reports realistic uncertainty for the tracked device

Explanation

Correct Answer

D:

A representative walk trace follows the correct floor and reports realistic uncertainty for the tracked device directly tests the proposed corrective action: Use supported Wi-Fi location methods and calibrated multi-AP floor context rather than a single signal observation. Wi-Fi location estimates require mapped APs, realistic uncertainty, appropriate time context and privacy-aware interpretation.

Incorrect Answers

A:

That observation would confirm another situation: An MSP exports Wi-Fi location trails for every organization without checking the recipient's permission to view person-related records. Here the selected action should produce: A representative walk trace follows the correct floor and reports realistic uncertainty for the tracked device.

B:

This check instead concerns a separate case: A school uses Wi-Fi device presence to produce an occupancy estimate but its report includes unrelated devices seen from outside the building. Here the selected action should produce: A representative walk trace follows the correct floor and reports realistic uncertainty for the tracked device.

C:

That evidence would establish success in a different scenario: A location dashboard aggregates client presence over a whole day and the team treats it as an instantaneous live headcount. Here the selected action should produce: A representative walk trace follows the correct floor and reports realistic uncertainty for the tracked device.

Question 94

A warehouse upgrades its access points to Wi-Fi 6 but its legacy scanner fleet supports only 802.11n and shows no OFDMA capability. The incident lead approves this next step: Validate client PHY capabilities before expecting Wi-Fi 6 efficiency improvements on those scanners. Which observation best confirms the correction worked?

  1. A supported test client reports actual negotiated links instead of relying on the AP product label
  2. A traffic test records both negotiated link rate and lower delivered payload throughput under the same conditions
  3. An updated supported client advertises 6 GHz capability and discovers the allowed test SSID
  4. A capability inventory separates 802.11n clients from HE-capable devices and documents observed airtime use

Explanation

Correct Answer

D:

A capability inventory separates 802.11n clients from HE-capable devices and documents observed airtime use directly tests the proposed corrective action: Validate client PHY capabilities before expecting Wi-Fi 6 efficiency improvements on those scanners. 802.11 PHY capability is negotiated per client and is not conferred automatically by an AP marketing label.

Incorrect Answers

A:

This check instead concerns a separate case: A WLAN design labels one 802.11be multi-link-capable access point as proof that every connected device uses simultaneous multi-link operation. Here the selected action should produce: A capability inventory separates 802.11n clients from HE-capable devices and documents observed airtime use.

B:

That evidence would establish success in a different scenario: An engineer counts the advertised PHY rate as guaranteed application throughput for a Wi-Fi 6 workstation. Here the selected action should produce: A capability inventory separates 802.11n clients from HE-capable devices and documents observed airtime use.

C:

That observation would confirm another situation: A Wi-Fi 6E site enables a 6 GHz SSID but leaves client operating-system drivers unable to recognize that band. Here the selected action should produce: A capability inventory separates 802.11n clients from HE-capable devices and documents observed airtime use.

Question 95

A clinic provides one shared SSID for staff, guests and IoT equipment without separate identity or traffic policy requirements. The intended correction is: Define distinct trust and access intents before choosing common or separate WLAN profiles. What evidence should be required before closing the incident?

  1. Test clients from each population reach only their permitted services under the approved design
  2. A representative client completes authentication, addressing and permitted application connectivity
  3. Terminal battery tests improve without missing critical application notifications
  4. Guest devices cannot reach staff services while approved Internet connectivity continues

Explanation

Correct Answer

A:

Test clients from each population reach only their permitted services under the approved design directly tests the proposed corrective action: Define distinct trust and access intents before choosing common or separate WLAN profiles. SSID availability, client admission, VLAN segmentation, QoS and actual service reachability are separate WLAN properties.

Incorrect Answers

B:

That evidence would establish success in a different scenario: An engineer measures AP packet counters but does not check if an authorized user can complete the required DNS and gateway exchanges. Here the selected action should produce: Test clients from each population reach only their permitted services under the approved design.

C:

That observation would confirm another situation: A warehouse supports barcode terminals with limited battery capacity but forces them to stay awake with unnecessarily frequent broadcast traffic. Here the selected action should produce: Test clients from each population reach only their permitted services under the approved design.

D:

This check instead concerns a separate case: A venue enables guest client isolation but visitors still reach employee servers through the site's unrestricted routing policy. Here the selected action should produce: Test clients from each population reach only their permitted services under the approved design.

Question 96

A campus statically assigns the same 5 GHz channel to adjacent APs and reports severe co-channel contention during lectures. The selected operator action is: Allow a supported RRM channel plan that accounts for RF overlap and available spectrum. Which result would demonstrate the intended network outcome?

  1. APs avoid overlapping wide-channel blocks that would consume each other's effective airtime
  2. The AP no longer causes unnecessary repeated channel moves during the protected event
  3. The mapped APs use compatible channel reuse and busy-hour contention declines
  4. The measured client uplink RSSI and retry rate improve while coverage remains adequate

Explanation

Correct Answer

C:

The mapped APs use compatible channel reuse and busy-hour contention declines directly tests the proposed corrective action: Allow a supported RRM channel plan that accounts for RF overlap and available spectrum. RRM choices balance interference, legal channel/power limits, cell reuse, client needs and actual service-impact evidence.

Incorrect Answers

A:

That observation would confirm another situation: A channel-planning script assumes a 160 MHz operating channel can coexist independently with several overlapping 80 MHz cells. Here the selected action should produce: The mapped APs use compatible channel reuse and busy-hour contention declines.

B:

This check instead concerns a separate case: An access point changes channels repeatedly during a critical presentation because RRM tuning is allowed to cause frequent disruptive reassignment. Here the selected action should produce: The mapped APs use compatible channel reuse and busy-hour contention declines.

D:

That evidence would establish success in a different scenario: A site has poor scanner uplink reliability because the AP transmit power is much stronger than the low-power client radio can support. Here the selected action should produce: The mapped APs use compatible channel reuse and busy-hour contention declines.

Question 97

A university maps three campuses into one Mist site despite different country settings, time zones and local policy boundaries. The recommended remediation is: Create site objects reflecting distinct real operational locations and assign access points accordingly. What is the best acceptance test for this change?

  1. Hardware inventory shows only its legitimate receiving organization as owner
  2. A consolidated view lists each building while local VLAN and RF differences are preserved
  3. The AP's organization/site identifiers and incident timeline match its physical installation
  4. AP inventory and incident timestamps display correct campus-specific site metadata

Explanation

Correct Answer

D:

AP inventory and incident timestamps display correct campus-specific site metadata directly tests the proposed corrective action: Create site objects reflecting distinct real operational locations and assign access points accordingly. Mist organizations provide ownership boundaries while sites represent actual locations with correct device membership and metadata.

Incorrect Answers

A:

This check instead concerns a separate case: A consultant moves an AP between two customers by changing its site name while leaving organization ownership unchanged. Here the selected action should produce: AP inventory and incident timestamps display correct campus-specific site metadata.

B:

That evidence would establish success in a different scenario: A managed-service customer wants a single dashboard for multiple buildings but insists that each building receive distinct local wireless policies. Here the selected action should produce: AP inventory and incident timestamps display correct campus-specific site metadata.

C:

That observation would confirm another situation: A device is accidentally assigned to a similarly named site in another time zone and displays unrelated troubleshooting data. Here the selected action should produce: AP inventory and incident timestamps display correct campus-specific site metadata.

Question 98

A newly installed AP receives a DHCP lease with a stale default gateway from an outdated relay scope and cannot reach its regional cloud endpoint. The change request proposes: Correct the management VLAN DHCP scope and routed gateway option without modifying client SSIDs. Which postchange finding most directly validates the action?

  1. A renewed lease supplies the proper gateway and the AP establishes its cloud-management connection
  2. A corrected time source supports trusted cloud TLS and consistent incident timestamps
  3. Test markers correspond to physical AP positions and follow-up diagnostics locate the correct floor
  4. Test clients validate certificates and complete the approved guest or enterprise onboarding flow

Explanation

Correct Answer

A:

A renewed lease supplies the proper gateway and the AP establishes its cloud-management connection directly tests the proposed corrective action: Correct the management VLAN DHCP scope and routed gateway option without modifying client SSIDs. Mist AP onboarding depends on local addressing, power, DNS, time, outbound management reachability and intended WLAN policy.

Incorrect Answers

B:

That evidence would establish success in a different scenario: A branch uses wrong time synchronization and Mist event logs show a TLS onboarding certificate error. Here the selected action should produce: A renewed lease supplies the proper gateway and the AP establishes its cloud-management connection.

C:

That observation would confirm another situation: A project copies an old floorplan with AP marker positions that do not correspond to the new building. Here the selected action should produce: A renewed lease supplies the proper gateway and the AP establishes its cloud-management connection.

D:

This check instead concerns a separate case: A new WLAN is deployed before the service identity and guest portal certificate chains are ready for client authentication. Here the selected action should produce: A renewed lease supplies the proper gateway and the AP establishes its cloud-management connection.

Question 99

A hotel guest portal displays successfully but allows full Internet browsing without requiring the configured acceptance step. The site engineer plans to: Correct portal enforcement and the preauthentication access policy for the WLAN. What evidence most clearly distinguishes success from a partial fix?

  1. An unauthenticated guest is redirected and gains only permitted access after completing the portal
  2. Representative supported phones and laptops both complete guest onboarding without broad prelogin access
  3. Wireless captures and client settings confirm the intended encryption profile independent of portal state
  4. An ordinary guest browser opens the portal without an identity mismatch or certificate warning

Explanation

Correct Answer

A:

An unauthenticated guest is redirected and gains only permitted access after completing the portal directly tests the proposed corrective action: Correct portal enforcement and the preauthentication access policy for the WLAN. Guest portals require effective prelogin, HTTPS, redirection, authentication and postlogin service authorization controls.

Incorrect Answers

B:

That observation would confirm another situation: A hotel captive portal loads on phones but fails on laptops because only one redirect URL is allowed and required companion resources are blocked. Here the selected action should produce: An unauthenticated guest is redirected and gains only permitted access after completing the portal.

C:

This check instead concerns a separate case: A site treats portal completion as proof that Wi-Fi link-layer traffic was encrypted on an open network. Here the selected action should produce: An unauthenticated guest is redirected and gains only permitted access after completing the portal.

D:

That evidence would establish success in a different scenario: A conference venue has a guest portal certificate whose server name does not match the redirect hostname and browsers warn of interception. Here the selected action should produce: An unauthenticated guest is redirected and gains only permitted access after completing the portal.

Question 100

A help desk sees one laptop repeatedly fail Wi-Fi login and asks Marvis about the whole organization without giving the affected client identifier. The incident lead approves this next step: Supply the relevant client, site and event timing for a targeted Marvis diagnostic query. Which outcome should the site engineer expect after the repair?

  1. The root-cause record identifies the actual missing VLAN or DHCP path and confirms restored leasing
  2. Client-specific events reveal the handoff delay and guide a targeted verified fix
  3. New client transactions agree with the updated policy state and the current diagnosis
  4. The answer references the actual laptop and exposes its failed authentication stage

Explanation

Correct Answer

D:

The answer references the actual laptop and exposes its failed authentication stage directly tests the proposed corrective action: Supply the relevant client, site and event timing for a targeted Marvis diagnostic query. Marvis reactive diagnosis requires the correct authorized client/site context and corroborating current operational measurements.

Incorrect Answers

A:

This check instead concerns a separate case: An engineer receives a Marvis finding about failed DHCP and immediately blames the AP without examining uplink VLAN configuration. Here the selected action should produce: The answer references the actual laptop and exposes its failed authentication stage.

B:

That evidence would establish success in a different scenario: A support analyst sees an excellent site-level Marvis summary but a named voice handset has repeated roaming disruptions. Here the selected action should produce: The answer references the actual laptop and exposes its failed authentication stage.

C:

That observation would confirm another situation: A hotel engineer queries Marvis after a WLAN policy update but the tool still references older events collected before the edit. Here the selected action should produce: The answer references the actual laptop and exposes its failed authentication stage.
