Mist AI Wireless, Specialist (JNCIS-MistAI-Wireless) JN0-452 Practice Test 87

Question 860

An engineer confuses modulation order with antenna count and claims adding a spatial stream automatically produces 4096-QAM. How should the team correct this specific WLAN problem?

  1. Evaluate the negotiated MLO links instead of comparing marketing aggregate PHY rates
  2. Check the required quality margin for high-order modulation before promising peak throughput
  3. Distinguish spatial multiplexing from QAM constellation and coding capabilities
  4. Use effective airtime, retransmissions and actual MCS to evaluate useful throughput

Explanation

Correct Answer

C:

A negotiated PHY rate depends on modulation, coding, streams and channel conditions and differs from application payload throughput. In the described case, distinguish spatial multiplexing from QAM constellation and coding capabilities resolves the identified control gap. Confirm with: The capability and link-rate report lists streams and modulation settings independently.

Incorrect Answers

A:

This is relevant to a separate modulation, coding and phy rates problem: A Wi-Fi 7 demonstration advertises a high aggregate link rate using multiple bands but a client establishes only one supported link. It does not directly address this incident, which instead calls for: Distinguish spatial multiplexing from QAM constellation and coding capabilities.

B:

This is relevant to a separate modulation, coding and phy rates problem: A planner assumes a 1024-QAM PHY rate will remain usable at the far edge of every 802.11ax cell. It does not directly address this incident, which instead calls for: Distinguish spatial multiplexing from QAM constellation and coding capabilities.

D:

This is relevant to a separate modulation, coding and phy rates problem: A dense WLAN uses a wide PHY channel but business video throughput falls due to repeated transmissions at low MCS. It does not directly address this incident, which instead calls for: Distinguish spatial multiplexing from QAM constellation and coding capabilities.

Question 861

A regional office moves APs between Mist sites but the operations log identifies only a human-readable device name reused elsewhere. Which action should the specialist recommend FIRST?

  1. Use event identifiers and deduplication in the operational alert receiver
  2. Route verified security-relevant wireless alerts into the proper incident workflow
  3. Use stable AP serials and site identifiers when correlating administrative events
  4. Restrict the suppression condition to the intended retry event class and explicitly preserve AP outage escalation

Explanation

Correct Answer

C:

Actionable alerts and audit records require correct routing, context, retention and confirmation of recovered service. In the described case, use stable AP serials and site identifiers when correlating administrative events resolves the identified control gap. Confirm with: The move history resolves the exact hardware and location with no name collision.

Incorrect Answers

A:

This is relevant to a separate alerts and administrative audit records problem: An MSSP receives the same AP outage notification many times and opens a separate incident ticket for each retry. It does not directly address this incident, which instead calls for: Use stable AP serials and site identifiers when correlating administrative events.

B:

This is relevant to a separate alerts and administrative audit records problem: A WLAN security incident appears in the AP alert list but is never shared with the authorized security-response team. It does not directly address this incident, which instead calls for: Use stable AP serials and site identifiers when correlating administrative events.

D:

This is relevant to a separate alerts and administrative audit records problem: A hospital alert-suppression filter intended for low-priority client retries accidentally matches critical AP disconnects because its pattern is too broad. It does not directly address this incident, which instead calls for: Use stable AP serials and site identifiers when correlating administrative events.

Question 862

A school tries to suppress all AI actions when one noisy client produces repeated warnings, hiding separate high-impact issues. What corrective step most directly addresses the wireless fault?

  1. Use Marvis proactive telemetry and supported synthetic validation to detect latent service failures
  2. Restrict high-impact autonomous actions by policy and choose driver-assist review when appropriate
  3. Confirm the proactive finding with current SLE and client impact evidence before a disruptive response
  4. Tune noisy client handling and preserve independent critical action visibility

Explanation

Correct Answer

D:

Proactive Marvis findings help detect network risk before users complain but do not remove the need for controlled verification. In the described case, tune noisy client handling and preserve independent critical action visibility resolves the identified control gap. Confirm with: The repeated low-impact signal is controlled while distinct real incidents remain discoverable.

Incorrect Answers

A:

This is relevant to a separate marvis proactive troubleshooting problem: A retail store has no connected users overnight and the operations team assumes no network problems can be identified before opening. It does not directly address this incident, which instead calls for: Tune noisy client handling and preserve independent critical action visibility.

B:

This is relevant to a separate marvis proactive troubleshooting problem: A hospital enables self-driving network changes for every anomaly and risks disrupting clinical radios during active procedures. It does not directly address this incident, which instead calls for: Tune noisy client handling and preserve independent critical action visibility.

C:

This is relevant to a separate marvis proactive troubleshooting problem: An AI-derived performance warning leads a campus NOC to disable an entire student WLAN before verifying whether the reported problem is ongoing. It does not directly address this incident, which instead calls for: Tune noisy client handling and preserve independent critical action visibility.

Question 863

A large auditorium is planned using a single AP at maximum power to cover every seat during a full-capacity conference. Which network-management change is most appropriate?

  1. Design sufficient small cells and channel reuse using measured density and application needs
  2. Use representative peak-hour client and airtime measurements before finalizing RRM choices
  3. Balance receive-side client link margins and AP power rather than increasing only downlink strength
  4. Analyze actual available spectrum, regulatory limits and neighboring BSS occupancy

Explanation

Correct Answer

A:

RRM choices balance interference, legal channel/power limits, cell reuse, client needs and actual service-impact evidence. In the described case, design sufficient small cells and channel reuse using measured density and application needs resolves the identified control gap. Confirm with: Busy-hour tests show acceptable airtime and throughput across representative seating areas.

Incorrect Answers

B:

This is relevant to a separate radio resource management (rrm) problem: A WLAN administrator interprets quiet RF at 3 AM as enough evidence to accept a capacity plan for lunchtime crowds. It does not directly address this incident, which instead calls for: Design sufficient small cells and channel reuse using measured density and application needs.

C:

This is relevant to a separate radio resource management (rrm) problem: A site has poor scanner uplink reliability because the AP transmit power is much stronger than the low-power client radio can support. It does not directly address this incident, which instead calls for: Design sufficient small cells and channel reuse using measured density and application needs.

D:

This is relevant to a separate radio resource management (rrm) problem: An engineer assumes dynamic channel selection always avoids co-channel interference even when only one permissible channel is available. It does not directly address this incident, which instead calls for: Design sufficient small cells and channel reuse using measured density and application needs.

Question 864

A school plans automatic RF selection but locks every AP to the same static 5 GHz channel anyway. What should the engineer investigate or configure next?

  1. Test client continuity and alternative-channel selection during a controlled DFS evacuation event
  2. Evaluate total channel reuse and interference against requested wide-channel throughput
  3. Measure non-Wi-Fi interference in the affected band and adjust coverage or device placement
  4. Remove conflicting static channel constraints and verify the supported radio-management policy

Explanation

Correct Answer

D:

Channel planning depends on supported frequency bands, local regulatory rules, widths and actual interference. In the described case, remove conflicting static channel constraints and verify the supported radio-management policy resolves the identified control gap. Confirm with: The controller-independent RF plan distributes feasible channels across the mapped cells.

Incorrect Answers

A:

This is relevant to a separate frequency bands and channel plans problem: A building uses DFS channels for critical client traffic but no failover testing covers forced channel moves. It does not directly address this incident, which instead calls for: Remove conflicting static channel constraints and verify the supported radio-management policy.

B:

This is relevant to a separate frequency bands and channel plans problem: A high-density stadium assumes wider 160 MHz channels always increase total usable capacity even when only a few non-overlapping channels remain. It does not directly address this incident, which instead calls for: Remove conflicting static channel constraints and verify the supported radio-management policy.

C:

This is relevant to a separate frequency bands and channel plans problem: A warehouse 2.4 GHz scanner loses packets whenever a nearby microwave operates during lunch. It does not directly address this incident, which instead calls for: Remove conflicting static channel constraints and verify the supported radio-management policy.

Question 865

An MSP reuses one customer-branded portal across two unrelated tenants and exposes the wrong terms and support contacts. Which response best follows from the observed evidence?

  1. Install a valid trusted certificate for the actual portal hostname and verify HTTPS behavior
  2. Enforce encrypted portal transport and minimize collected guest information according to policy
  3. Scope guest portal objects, branding and data collection to the correct organization
  4. Check the supported portal walled garden and redirect dependencies for both client classes

Explanation

Correct Answer

C:

Guest portals require effective prelogin, HTTPS, redirection, authentication and postlogin service authorization controls. In the described case, scope guest portal objects, branding and data collection to the correct organization resolves the identified control gap. Confirm with: Each customer's test guest receives the matching approved portal and separate visitor records.

Incorrect Answers

A:

This is relevant to a separate guest captive portals problem: A conference venue has a guest portal certificate whose server name does not match the redirect hostname and browsers warn of interception. It does not directly address this incident, which instead calls for: Scope guest portal objects, branding and data collection to the correct organization.

B:

This is relevant to a separate guest captive portals problem: An employee guest portal is embedded in an HTTP page that collects personal information without trusted HTTPS. It does not directly address this incident, which instead calls for: Scope guest portal objects, branding and data collection to the correct organization.

D:

It does not directly address this incident, which instead calls for: Scope guest portal objects, branding and data collection to the correct organization.

Question 866

A facility installs an AP inside a metal cabinet and the team blames cloud service health when Wi-Fi disappears outside. What is the most defensible next troubleshooting action?

  1. Move or correctly antenna-feed the radio so the metal enclosure no longer shields the intended coverage area
  2. Measure the actual obstruction and multipath environment before selecting a placement
  3. Measure bidirectional link budgets and client uplink quality instead of using AP transmit RSSI alone
  4. Investigate multipath fading and client antenna behavior with a measured physical survey

Explanation

Correct Answer

A:

RF planning must account for bidirectional signal, noise, building attenuation and actual antenna propagation. In the described case, move or correctly antenna-feed the radio so the metal enclosure no longer shields the intended coverage area resolves the identified control gap. Confirm with: A verified walk test restores the expected RF field outside the cabinet and client associations succeed.

Incorrect Answers

B:

This is relevant to a separate rf fundamentals and propagation problem: An office places an AP behind an elevator shaft and assumes line-of-sight signal loss is identical to ordinary drywall attenuation. It does not directly address this incident, which instead calls for: Move or correctly antenna-feed the radio so the metal enclosure no longer shields the intended coverage area.

C:

This is relevant to a separate rf fundamentals and propagation problem: A classroom reports strong AP signal but poor client uploads because the handset's return path is much weaker than the downlink.

  1. Inspect policy synchronization and actual AP deployment state before marking the task complete
  2. Retire the SSID from the authoritative applied template and verify propagation
  3. Configure a supported tunnel termination association and verify the AP-to-edge path
  4. Correct the chosen forwarding mode or security enforcement design before handover

Explanation

Correct Answer

D:

Mist WLAN configurations require correct effective inheritance and verified delivery to the intended access points. In the described case, correct the chosen forwarding mode or security enforcement design before handover resolves the identified control gap. Confirm with: A packet path test verifies frames traverse the intended inspection point for the authorized network.

Incorrect Answers

A:

This is relevant to a separate mist wlan configurations problem: A WLAN change is saved successfully in Mist but one disconnected AP retains the previous SSID after reconnecting. It does not directly address this incident, which instead calls for: Correct the chosen forwarding mode or security enforcement design before handover.

B:

This is relevant to a separate mist wlan configurations problem: A retail chain must remove an obsolete SSID, yet it remains advertised because the organization WLAN template still includes it. It does not directly address this incident, which instead calls for: Correct the chosen forwarding mode or security enforcement design before handover.

C:

This is relevant to a separate mist wlan configurations problem: A guest WLAN is tunneled toward Mist Edge but its site does not have a reachable edge-cluster assignment. It does not directly address this incident, which instead calls for: Correct the chosen forwarding mode or security enforcement design before handover.

Question 868

A change ticket marks a WLAN edit successful as soon as the portal saves, but offline APs still carry old settings. How should the team correct this specific WLAN problem?

  1. Inventory client radio capabilities and stage a supported multi-band migration
  2. Validate actual device configuration propagation and live client connectivity before closing the ticket
  3. Coordinate WLAN-to-network mapping with the wired AP uplink and relevant trunk configuration
  4. Modify the supported source WLAN object and deliver the change through governed configuration

Explanation

Correct Answer

B:

WLAN objects must be scoped to the intended radios, sites, networks and associated security and portal dependencies. In the described case, validate actual device configuration propagation and live client connectivity before closing the ticket resolves the identified control gap. Confirm with: Returning APs adopt the intended revision and representative client associations succeed.

Incorrect Answers

A:

This is relevant to a separate wlan configuration objects and deployment problem: An engineer changes a WLAN's radio-band selection without checking whether the affected client fleet supports the replacement band. It does not directly address this incident, which instead calls for: Validate actual device configuration propagation and live client connectivity before closing the ticket.

C:

This is relevant to a separate wlan configuration objects and deployment problem: A field engineer changes an SSID's VLAN ID but the switching fabric never carries that VLAN to the access point. It does not directly address this incident, which instead calls for: Validate actual device configuration propagation and live client connectivity before closing the ticket.

D:

This is relevant to a separate wlan configuration objects and deployment problem: A managed SSID is renamed directly on a single AP outside the authoritative template and the cloud later reverts the edit. It does not directly address this incident, which instead calls for: Validate actual device configuration propagation and live client connectivity before closing the ticket.

Question 869

An office Wi-Fi dashboard shows only 61 percent of sessions meeting an SLE threshold and a manager treats that as 61 percent AP uptime. Which action should the specialist recommend FIRST?

  1. Use the Association classifier and timed management exchange evidence
  2. Check the selected SLE definition and measured denominator rather than using the number as uptime
  3. Interpret Coverage as signal quality and Capacity as available airtime or contention experience
  4. Analyze the authorization time contribution in Time to Connect and EAP transactions

Explanation

Correct Answer

B:

Wireless SLEs measure defined client-experience success and classifiers; different metrics and denominators are not interchangeable. In the described case, check the selected SLE definition and measured denominator rather than using the number as uptime resolves the identified control gap. Confirm with: The dashboard separates actual user attempts from AP Health availability measurements.

Incorrect Answers

A:

This is relevant to a separate wireless assurance sle metric interpretation problem: A warehouse has Time to Connect failures related to delayed association responses and the engineer examines only Internet reachability. It does not directly address this incident, which instead calls for: Check the selected SLE definition and measured denominator rather than using the number as uptime.

C:

This is relevant to a separate wireless assurance sle metric interpretation problem: A technician compares Coverage SLE to Capacity SLE and assumes both report the same received signal strength. It does not directly address this incident, which instead calls for: Check the selected SLE definition and measured denominator rather than using the number as uptime.

D:

This is relevant to a separate wireless assurance sle metric interpretation problem: A school reports long wireless connection times even when the DHCP server is healthy but its identity provider is overloaded. It does not directly address this incident, which instead calls for: Check the selected SLE definition and measured denominator rather than using the number as uptime.
