Mist AI Wireless, Specialist (JNCIS-MistAI-Wireless) JN0-452 Practice Test 79

Question 780

A conference center wants a quick answer about an individual AP but sends a vague request with no serial and several APs sharing similar names. Which configuration or control should the operator select?

  1. Preserve authorized organization, site and client source references with the summary
  2. Use Marvis for authorized network management use cases rather than unrelated business records
  3. Set the correct organization and site before using natural-language network diagnosis
  4. Identify the intended AP with a unique device identifier and relevant site scope

Explanation

Correct Answer

D:

Conversational Marvis queries should use supported language, clear network context, correct identities and evidence-aware interpretation. In the described case, identify the intended AP with a unique device identifier and relevant site scope resolves the identified control gap. Confirm with: The response reports the actual AP health and explains its recent events accurately.

Incorrect Answers

A:

This is relevant to a separate marvis languages and conversational queries problem: A technician copies a Marvis answer into a ticket without identifying which organization supplied the diagnostic result. It does not directly address this incident, which instead calls for: Identify the intended AP with a unique device identifier and relevant site scope.

B:

This is relevant to a separate marvis languages and conversational queries problem: A security team treats Marvis natural-language support as a general search engine for private employee payroll data. It does not directly address this incident, which instead calls for: Identify the intended AP with a unique device identifier and relevant site scope.

C:

This is relevant to a separate marvis languages and conversational queries problem: A school support engineer requests DHCP analysis while the portal is currently scoped to a site outside the school. It does not directly address this incident, which instead calls for: Identify the intended AP with a unique device identifier and relevant site scope.

Question 781

A project copies an old floorplan with AP marker positions that do not correspond to the new building. The site engineer plans to: Survey actual access point locations and update mapping before enabling location-dependent features. What observation would justify marking this case resolved?

  1. Test clients validate certificates and complete the approved guest or enterprise onboarding flow
  2. Test markers correspond to physical AP positions and follow-up diagnostics locate the correct floor
  3. The AP connects to the cloud and test clients reach their correct local network segment
  4. The AP resolves the correct endpoint and establishes its authorized management session

Explanation

Correct Answer

B:

Test markers correspond to physical AP positions and follow-up diagnostics locate the correct floor directly tests the proposed corrective action: Survey actual access point locations and update mapping before enabling location-dependent features. Mist AP onboarding depends on local addressing, power, DNS, time, outbound management reachability and intended WLAN policy.

Incorrect Answers

A:

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: Test markers correspond to physical AP positions and follow-up diagnostics locate the correct floor.

C:

That evidence would establish success in a different scenario: An AP setup team assigns WLANs to a site before confirming the wired switch trunk carries the intended client VLANs. Here the selected action should produce: Test markers correspond to physical AP positions and follow-up diagnostics locate the correct floor.

D:

That observation would confirm another situation: An AP has a management address but its DNS resolver cannot translate the assigned regional Mist service hostname. Here the selected action should produce: Test markers correspond to physical AP positions and follow-up diagnostics locate the correct floor.

Question 782

A shopping center wants custom guest terms but saves the form without associating it with its deployed WLAN. The incident lead approves this next step: Connect the configured guest portal and terms presentation to the active WLAN profile. Which observation best confirms the correction worked?

  1. An unauthenticated guest is redirected and gains only permitted access after completing the portal
  2. An expired visitor cannot reauthenticate and a current guest maintains permitted connectivity
  3. New guest devices see the current approved terms before access is granted
  4. The guest client moves to permitted access and reaches approved external destinations after sign-in

Explanation

Correct Answer

C:

New guest devices see the current approved terms before access is granted directly tests the proposed corrective action: Connect the configured guest portal and terms presentation to the active WLAN profile. Guest portals require effective prelogin, HTTPS, redirection, authentication and postlogin service authorization controls.

Incorrect Answers

A:

That evidence would establish success in a different scenario: A hotel guest portal displays successfully but allows full Internet browsing without requiring the configured acceptance step. Here the selected action should produce: New guest devices see the current approved terms before access is granted.

B:

That observation would confirm another situation: A hotel sets guest vouchers to remain usable forever even though visit entitlements expire after checkout. Here the selected action should produce: New guest devices see the current approved terms before access is granted.

D:

This check instead concerns a separate case: A campus guest portal redirects correctly but its backend authorization succeeds while the user remains isolated after acceptance. Here the selected action should produce: New guest devices see the current approved terms before access is granted.

Question 783

A VoIP fleet uses robust low-rate modulation yet voice packet loss persists because the shared channel is saturated. The intended correction is: Investigate MAC contention separately from modulation robustness when identifying the bottleneck. What evidence should be required before closing the incident?

  1. Channel busy time explains missed voice frames even as the selected robust MCS remains stable
  2. Association data explains why the clients have different expected nominal PHY rate ceilings
  3. Time-aligned client metrics show lower MCS with weaker quality and an improved rate after moving closer
  4. Link measurements show the one-stream ceiling and identify whether other airtime constraints remain

Explanation

Correct Answer

A:

Channel busy time explains missed voice frames even as the selected robust MCS remains stable directly tests the proposed corrective action: Investigate MAC contention separately from modulation robustness when identifying the bottleneck. A negotiated PHY rate depends on modulation, coding, streams and channel conditions and differs from application payload throughput.

Incorrect Answers

B:

That observation would confirm another situation: A field engineer compares two same-band clients with similar RSSI but different negotiated streams and MCS rates. Here the selected action should produce: Channel busy time explains missed voice frames even as the selected robust MCS remains stable.

C:

This check instead concerns a separate case: A client moves behind a concrete wall and its selected MCS steps down while packet errors rise. Here the selected action should produce: Channel busy time explains missed voice frames even as the selected robust MCS remains stable.

D:

That evidence would establish success in a different scenario: A deployment uses 6 GHz with modern-capable devices but results remain slow because clients have only one supported spatial stream. Here the selected action should produce: Channel busy time explains missed voice frames even as the selected robust MCS remains stable.

Question 784

A customer reports a Marvis Action that appears locked or unavailable while its Marvis subscription has expired. The selected operator action is: Verify entitlement and supported feature access before assuming the AI service is malfunctioning. Which result would demonstrate the intended network outcome?

  1. The AP returns online and affected client SLEs recover under current telemetry
  2. The relevant licensed Action detail becomes available to authorized staff after entitlement correction
  3. The recovered data tunnel and guest client path resolve the issue independently of radio settings
  4. The work order names correct site and APs with measurable outcome checks

Explanation

Correct Answer

B:

The relevant licensed Action detail becomes available to authorized staff after entitlement correction directly tests the proposed corrective action: Verify entitlement and supported feature access before assuming the AI service is malfunctioning. Marvis Actions can guide operators or execute permitted self-driving changes; scope, authorization and outcome remain essential.

Incorrect Answers

A:

This check instead concerns a separate case: A campus engineer marks a Marvis AP offline Action resolved after pressing Acknowledge even though the device remains unreachable. Here the selected action should produce: The relevant licensed Action detail becomes available to authorized staff after entitlement correction.

C:

That evidence would establish success in a different scenario: A WLAN Action indicates a tunnel anomaly at Mist Edge but the NOC changes only the 2.4 GHz channel plan. Here the selected action should produce: The relevant licensed Action detail becomes available to authorized staff after entitlement correction.

D:

That observation would confirm another situation: A managed service provider views a global Actions dashboard and starts repairing one branch without identifying the exact affected APs. Here the selected action should produce: The relevant licensed Action detail becomes available to authorized staff after entitlement correction.

Question 785

A developer installs a generic BLE beacon on a cart and assumes Mist can associate the device with an employee record without registering any tag identity. The recommended remediation is: Create the authorized mapping from the observed BLE tag identifier to the named tracked asset. What is the best acceptance test for this change?

  1. Representative users receive the expected beacon signal in each designated service zone
  2. Engagement messages and asset-tag observations both succeed within supported service limits
  3. A representative phone test locates known points using the current AP map rather than obsolete positions
  4. The device is listed with its correct identity in the permitted asset tracking view

Explanation

Correct Answer

D:

The device is listed with its correct identity in the permitted asset tracking view directly tests the proposed corrective action: Create the authorized mapping from the observed BLE tag identifier to the named tracked asset. vBLE Engagement transmits positioning beacons while Asset Visibility listens for BLE tag advertisements; mapping and hardware matter.

Incorrect Answers

A:

That evidence would establish success in a different scenario: A campus enables a virtual BLE array only on one AP but expects continuous location guidance throughout several separate floors. Here the selected action should produce: The device is listed with its correct identity in the permitted asset tracking view.

B:

That observation would confirm another situation: An engineer enables both virtual beacon transmission and BLE-tag reception on a constrained AP without reviewing the supported update and performance behavior. Here the selected action should produce: The device is listed with its correct identity in the permitted asset tracking view.

C:

This check instead concerns a separate case: A site expects BLE positioning to remain stable after moving access points but never adjusts beam geometry or floorplan references. Here the selected action should produce: The device is listed with its correct identity in the permitted asset tracking view.

Question 786

A campus waits for users to complain about poor roaming even though historical Marvis findings repeatedly identify a common RF corridor problem. The change request proposes: Use proactive action trends to plan a verified site-specific radio or client fix. Which postchange finding most directly validates the action?

  1. An off-hours test detects the simulated address or DNS issue before staff arrive
  2. An unsafe proposed change requires accountable approval while safe allowed tasks remain available
  3. After the controlled change recurring handoff problems and matching action counts decrease
  4. The affected offline AP inventory is visible and not excluded from the incident assessment

Explanation

Correct Answer

C:

After the controlled change recurring handoff problems and matching action counts decrease directly tests the proposed corrective action: Use proactive action trends to plan a verified site-specific radio or client fix. Proactive Marvis findings help detect network risk before users complain but do not remove the need for controlled verification.

Incorrect Answers

A:

That observation would confirm another situation: A retail store has no connected users overnight and the operations team assumes no network problems can be identified before opening. Here the selected action should produce: After the controlled change recurring handoff problems and matching action counts decrease.

B:

This check instead concerns a separate case: A hospital enables self-driving network changes for every anomaly and risks disrupting clinical radios during active procedures. Here the selected action should produce: After the controlled change recurring handoff problems and matching action counts decrease.

D:

That evidence would establish success in a different scenario: An AP fleet starts losing cloud connectivity yet the proactive dashboard is filtered to only the still-online test devices. Here the selected action should produce: After the controlled change recurring handoff problems and matching action counts decrease.

Question 787

An engineer measures AP packet counters but does not check if an authorized user can complete the required DNS and gateway exchanges. The site engineer plans to: Test the end-to-end WLAN service beyond radio association with client-specific flows. What evidence most clearly distinguishes success from a partial fix?

  1. Authorized and unauthorized clients on the same SSID receive different permitted access as intended
  2. Guest devices cannot reach staff services while approved Internet connectivity continues
  3. A busy-hour voice test meets latency objectives while background transfers remain authorized
  4. A representative client completes authentication, addressing and permitted application connectivity

Explanation

Correct Answer

D:

A representative client completes authentication, addressing and permitted application connectivity directly tests the proposed corrective action: Test the end-to-end WLAN service beyond radio association with client-specific flows. SSID availability, client admission, VLAN segmentation, QoS and actual service reachability are separate WLAN properties.

Incorrect Answers

A:

This check instead concerns a separate case: A WLAN owner treats its naming convention as a security policy and allows full network access to any authenticated user of a particular SSID. Here the selected action should produce: A representative client completes authentication, addressing and permitted application connectivity.

B:

That evidence would establish success in a different scenario: 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: A representative client completes authentication, addressing and permitted application connectivity.

C:

That observation would confirm another situation: A campus WLAN design gives voice handsets and bulk backup endpoints identical airtime priority under heavy usage. Here the selected action should produce: A representative client completes authentication, addressing and permitted application connectivity.

Question 788

A technician claims that every AP can transmit at identical 6 GHz power outdoors because it is a globally unlicensed band. The incident lead approves this next step: Check current local 6 GHz indoor-outdoor and power restrictions for the exact deployment class. Which outcome should the site engineer expect after the repair?

  1. The approved channel and power inventory corresponds to the site's regulatory region and installation type
  2. A capacity simulation identifies the usable AP channel reuse count and representative client throughput
  3. Spectrum and airtime observations show fewer mutually interfering neighboring transmissions
  4. After replan adjacent cells have distinguishable channels and measured client contention falls

Explanation

Correct Answer

A:

The approved channel and power inventory corresponds to the site's regulatory region and installation type directly tests the proposed corrective action: Check current local 6 GHz indoor-outdoor and power restrictions for the exact deployment class. Channel planning depends on supported frequency bands, local regulatory rules, widths and actual interference.

Incorrect Answers

B:

That evidence would establish success in a different scenario: A high-density stadium assumes wider 160 MHz channels always increase total usable capacity even when only a few non-overlapping channels remain. Here the selected action should produce: The approved channel and power inventory corresponds to the site's regulatory region and installation type.

C:

That observation would confirm another situation: A hospital leaves all 2.4 GHz access points on channel one even though overlapping cells share a long corridor. Here the selected action should produce: The approved channel and power inventory corresponds to the site's regulatory region and installation type.

D:

This check instead concerns a separate case: An operator assigns an 80 MHz channel in 5 GHz to every neighboring classroom AP without reviewing channel reuse. Here the selected action should produce: The approved channel and power inventory corresponds to the site's regulatory region and installation type.

Question 789

A long hallway deployment suffers deep signal nulls where reflections combine destructively despite nearby AP proximity. The intended correction is: Investigate multipath fading and client antenna behavior with a measured physical survey. What observation would justify marking this case resolved?

  1. Client timeline shows stable association and isolates the missing DHCP response as the true fault
  2. A verified walk test restores the expected RF field outside the cabinet and client associations succeed
  3. Multiple positions or antenna orientations remove persistent coverage nulls for representative clients
  4. Users remain covered across the intended path and the site map shows no new blind sectors

Explanation

Correct Answer

C:

Multiple positions or antenna orientations remove persistent coverage nulls for representative clients directly tests the proposed corrective action: Investigate multipath fading and client antenna behavior with a measured physical survey. RF planning must account for bidirectional signal, noise, building attenuation and actual antenna propagation.

Incorrect Answers

A:

That observation would confirm another situation: An organization blames poor RF for a client that consistently fails DHCP after successful association at excellent signal level. Here the selected action should produce: Multiple positions or antenna orientations remove persistent coverage nulls for representative clients.

B:

This check instead concerns a separate case: A facility installs an AP inside a metal cabinet and the team blames cloud service health when Wi-Fi disappears outside. Here the selected action should produce: Multiple positions or antenna orientations remove persistent coverage nulls for representative clients.

D:

That evidence would establish success in a different scenario: A remote office compares two antenna options only by maximum dBi gain without checking the azimuth coverage needed by moving users. Here the selected action should produce: Multiple positions or antenna orientations remove persistent coverage nulls for representative clients.

Question 790

A Marvis Mini indicates a problem during a network incident but the technician looks only at an old cached result after a successful repair. The recommended remediation is: Run or inspect a fresh supported validation cycle to prove the service is now healthy. What is the best acceptance test for this change?

  1. A handset roam test measures the actual handoff behavior independently of Mini status
  2. A reporting matrix identifies which network contexts were tested and which still need validation
  3. After supported version updates, the expected site Minis tests execute successfully
  4. Current test timestamps and results show the formerly failed stage passing after remediation

Explanation

Correct Answer

D:

Current test timestamps and results show the formerly failed stage passing after remediation directly tests the proposed corrective action: Run or inspect a fresh supported validation cycle to prove the service is now healthy. Marvis Minis is a synthetic network validation capability, not proof of every real client experience or unsupported service.

Incorrect Answers

A:

This check instead concerns a separate case: A customer assumes a successful Marvis Mini probe proves that an employee's laptop can roam across ten APs without a voice interruption. Here the selected action should produce: Current test timestamps and results show the formerly failed stage passing after remediation.

B:

That evidence would establish success in a different scenario: A test for one VLAN passes and the help desk assumes every other SSID and security policy is equally correct. Here the selected action should produce: Current test timestamps and results show the formerly failed stage passing after remediation.

C:

That observation would confirm another situation: An IT engineer enables Minis but one AP at the site runs firmware below the feature's supported software prerequisite. Here the selected action should produce: Current test timestamps and results show the formerly failed stage passing after remediation.
