Mist AI Wireless, Specialist (JNCIS-MistAI-Wireless) JN0-452 Practice Test 73

Question 720

A WLAN disconnect follows an AP firmware update but the engineer cannot tell whether affected clients share a device model. The change request proposes: Correlate firmware change history with actual client type and failure timestamps. Which result would demonstrate the intended network outcome?

  1. Guest-to-guest communication fails across both wireless and routed paths while Internet remains available
  2. The kiosk recovers without introducing authentication failures across the remaining organization
  3. The AP advertises the campus SSID and the valid student completes association and authentication
  4. The postchange report identifies the impacted client cohort and confirms improvement after an approved repair

Explanation

Correct Answer

D:

The postchange report identifies the impacted client cohort and confirms improvement after an approved repair directly tests the proposed corrective action: Correlate firmware change history with actual client type and failure timestamps. Wireless faults should be isolated at the actual RF, association, authorization, DHCP, policy or application stage.

Incorrect Answers

A:

That observation would confirm another situation: A school disables client-to-client communication yet two guest devices can communicate through a routed subnet outside the AP. Here the selected action should produce: The postchange report identifies the impacted client cohort and confirms improvement after an approved repair.

B:

This check instead concerns a separate case: An operator changes a global WLAN security setting to repair one kiosk and unintentionally disconnects every other site. Here the selected action should produce: The postchange report identifies the impacted client cohort and confirms improvement after an approved repair.

C:

That evidence would establish success in a different scenario: A student cannot join the expected wireless network because its AP is claimed but not assigned to the right campus site. Here the selected action should produce: The postchange report identifies the impacted client cohort and confirms improvement after an approved repair.

Question 721

An AP hears a neighboring company WLAN using the same SSID but operations automatically labels it malicious without checking physical or ownership context. What corrective step most directly addresses the wireless fault?

  1. Investigate unauthorized SSID and authentication server identity together using WIDS evidence
  2. Correlate intrusion event history with SLE and client timeline evidence before assigning root cause
  3. Investigate wired attachment, inventory and physical location to determine the rogue-device category
  4. Validate SSID collision, BSSID and authorization evidence before classifying the device

Explanation

Correct Answer

D:

Wireless intrusion monitoring requires evidence-based classification of rogue, interfering and authorized devices and bounded response. In the described case, validate SSID collision, BSSID and authorization evidence before classifying the device resolves the identified control gap. Confirm with: The classification report separates coincidental neighboring networks from actual enterprise impersonation.

Incorrect Answers

A:

This is relevant to a separate wireless intrusion detection and prevention problem: A branch identifies an evil-twin SSID but analysts never compare the fake authentication portal with the approved server certificate. It does not directly address this incident, which instead calls for: Validate SSID collision, BSSID and authorization evidence before classifying the device.

B:

This is relevant to a separate wireless intrusion detection and prevention problem: A campus receives frequent WIPS events during a conference but no analyst checks whether the timestamps align with the reported client failures. It does not directly address this incident, which instead calls for: Validate SSID collision, BSSID and authorization evidence before classifying the device.

C:

This is relevant to a separate wireless intrusion detection and prevention problem: A security report calls every unrecognized BSSID rogue without distinguishing unauthorized devices connected to enterprise wired infrastructure. It does not directly address this incident, which instead calls for: Validate SSID collision, BSSID and authorization evidence before classifying the device.

Question 722

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. Which network-management change is most appropriate?

  1. Enable the supported vBLE arrays on the required corridor APs and validate application map integration
  2. Recalibrate BLE coverage and virtual beacon placement when physical AP positions change
  3. Apply the documented combined-feature configuration and verify device performance under simultaneous use
  4. Create the authorized mapping from the observed BLE tag identifier to the named tracked asset

Explanation

Correct Answer

D:

vBLE Engagement transmits positioning beacons while Asset Visibility listens for BLE tag advertisements; mapping and hardware matter. In the described case, create the authorized mapping from the observed BLE tag identifier to the named tracked asset resolves the identified control gap. Confirm with: The device is listed with its correct identity in the permitted asset tracking view.

Incorrect Answers

A:

This is relevant to a separate virtual bluetooth low energy problem: A conference venue has active vBLE Engagement at its front lobby only, leaving corridor AP virtual arrays disabled and indoor turn-by-turn guidance incomplete. It does not directly address this incident, which instead calls for: Create the authorized mapping from the observed BLE tag identifier to the named tracked asset.

B:

This is relevant to a separate virtual bluetooth low energy problem: A site expects BLE positioning to remain stable after moving access points but never adjusts beam geometry or floorplan references. It does not directly address this incident, which instead calls for: Create the authorized mapping from the observed BLE tag identifier to the named tracked asset.

C:

This is relevant to a separate virtual bluetooth low energy problem: An engineer enables both virtual beacon transmission and BLE-tag reception on a constrained AP without reviewing the supported update and performance behavior. It does not directly address this incident, which instead calls for: Create the authorized mapping from the observed BLE tag identifier to the named tracked asset.

Question 723

An engineer counts the advertised PHY rate as guaranteed application throughput for a Wi-Fi 6 workstation. What should the engineer investigate or configure next?

  1. Parse the captured wireless management or action frame according to the 802.11 frame format
  2. Separate negotiated PHY speed from MAC overhead, contention and usable application throughput
  3. Examine negotiated capabilities and channel scheduling rather than treating MU-MIMO as an always-active mode
  4. Confirm the client radio standards and bands before enabling a 6 GHz-only WLAN

Explanation

Correct Answer

B:

802.11 PHY capability is negotiated per client and is not conferred automatically by an AP marketing label. In the described case, separate negotiated PHY speed from MAC overhead, contention and usable application throughput resolves the identified control gap. Confirm with: A traffic test records both negotiated link rate and lower delivered payload throughput under the same conditions.

Incorrect Answers

A:

This is relevant to a separate 802.11 phy protocols problem: An auditor mistakes an 802.11 action frame for an ordinary Ethernet frame and expects wired protocol fields in its native header. It does not directly address this incident, which instead calls for: Separate negotiated PHY speed from MAC overhead, contention and usable application throughput.

C:

This is relevant to a separate 802.11 phy protocols problem: An access point supports both SU-MIMO and MU-MIMO, but support staff assumes multiuser transmission is used for every small packet. It does not directly address this incident, which instead calls for: Separate negotiated PHY speed from MAC overhead, contention and usable application throughput.

D:

This is relevant to a separate 802.11 phy protocols problem: A conference venue requires Wi-Fi 6E capacity but its purchased client tablets support only 5 GHz 802.11ac radios. It does not directly address this incident, which instead calls for: Separate negotiated PHY speed from MAC overhead, contention and usable application throughput.

Question 724

A university wants a consistent Coverage success target but varies the configured RSSI goal arbitrarily by campus without documentation. Which response best follows from the observed evidence?

  1. Use a documented service-specific coverage target and justified local exceptions
  2. Configure and interpret Successful Connects separately from Time to Connect
  3. Keep the appropriate entire service population or a representative approved client cohort in the SLE scope
  4. Tailor handoff success requirements to the critical voice application's approved service objectives

Explanation

Correct Answer

A:

SLE thresholds must express documented user-service goals with transparent scope, denominator and change history. In the described case, use a documented service-specific coverage target and justified local exceptions resolves the identified control gap. Confirm with: Per-site success rates can be compared using the same stated RSSI goal or clearly recorded exceptions.

Incorrect Answers

B:

This is relevant to a separate configuring wireless sle thresholds problem: A company uses one WLAN goal to measure both association success and time spent completing already successful connections. It does not directly address this incident, which instead calls for: Use a documented service-specific coverage target and justified local exceptions.

C:

This is relevant to a separate configuring wireless sle thresholds problem: A school changes a radio channel plan and then selects only the students' most capable laptops for postchange SLE verification. It does not directly address this incident, which instead calls for: Use a documented service-specific coverage target and justified local exceptions.

D:

This is relevant to a separate configuring wireless sle thresholds problem: A roaming SLE is set according to an office laptop tolerance despite life-safety voice devices requiring lower interruption. It does not directly address this incident, which instead calls for: Use a documented service-specific coverage target and justified local exceptions.

Question 725

A team deploys two edge appliances but both use the same physical power feed and uplink path during a resilience demonstration. What is the most defensible next troubleshooting action?

  1. Assess independent infrastructure failure domains for the active and backup Mist Edge paths
  2. Validate the AP-to-edge tunnel path and documented transport requirements independently of cloud registration
  3. Validate data-center service reachability for tunneled WLAN clients including identity and address services
  4. Match Mist Edge responsibilities to the specific tunneled WLAN service rather than all AP traffic

Explanation

Correct Answer

A:

Mist Edge terminates selected tunneled WLAN data paths and needs independent tunnel, interface, routing, capacity and failover checks. In the described case, assess independent infrastructure failure domains for the active and backup Mist Edge paths resolves the identified control gap. Confirm with: A controlled power or link failure leaves at least one supported tunnel termination available.

Incorrect Answers

B:

This is relevant to a separate juniper mist edge tunneling and resilience problem: A branch AP can reach the cloud but its configured Mist Edge tunnel endpoint has no reachable path through the site firewall. It does not directly address this incident, which instead calls for: Assess independent infrastructure failure domains for the active and backup Mist Edge paths.

C:

This is relevant to a separate juniper mist edge tunneling and resilience problem: An engineer sends a corporate WLAN through the edge but leaves the route to the enterprise authentication server absent. It does not directly address this incident, which instead calls for: Assess independent infrastructure failure domains for the active and backup Mist Edge paths.

D:

This is relevant to a separate juniper mist edge tunneling and resilience problem: An architect assumes Juniper Mist Edge processes every locally bridged wireless flow even when no WLAN tunnel is assigned. It does not directly address this incident, which instead calls for: Assess independent infrastructure failure domains for the active and backup Mist Edge paths.

Question 726

A WLAN disconnect follows an AP firmware update but the engineer cannot tell whether affected clients share a device model. Which configuration or control should the operator select?

  1. Correlate firmware change history with actual client type and failure timestamps
  2. Inspect device band and security capability versus the 6 GHz WLAN configuration
  3. Roll back broad changes and apply a scoped compatible exception after client capability assessment
  4. Use client and RADIUS timelines to isolate EAP authorization rather than increasing transmit power

Explanation

Correct Answer

A:

Wireless faults should be isolated at the actual RF, association, authorization, DHCP, policy or application stage. In the described case, correlate firmware change history with actual client type and failure timestamps resolves the identified control gap. Confirm with: The postchange report identifies the impacted client cohort and confirms improvement after an approved repair.

Incorrect Answers

B:

This is relevant to a separate wlan configuration and troubleshooting problem: A university enables a Wi-Fi 6E WLAN but older laptops cannot see it at all. It does not directly address this incident, which instead calls for: Correlate firmware change history with actual client type and failure timestamps.

C:

This is relevant to a separate wlan configuration and troubleshooting problem: An operator changes a global WLAN security setting to repair one kiosk and unintentionally disconnects every other site. It does not directly address this incident, which instead calls for: Correlate firmware change history with actual client type and failure timestamps.

D:

This is relevant to a separate wlan configuration and troubleshooting problem: A hospital handset fails enterprise WLAN authentication while the AP radio reports good coverage. It does not directly address this incident, which instead calls for: Correlate firmware change history with actual client type and failure timestamps.

Question 727

A central administrator changes an RF template without documenting who approved the change or which access points inherited it. How should the team correct this specific WLAN problem?

  1. Bind the WLAN configuration to the correct deployment scope and verify effective AP settings
  2. Apply governed versioning and validate the actual target scope before deployment
  3. Distinguish saved cloud intent from confirmed AP configuration delivery and acceptance
  4. Use supported site-specific VLAN mapping or a scoped configuration override

Explanation

Correct Answer

B:

Reusable Mist configuration objects require correct references, inheritance, target membership and verified device delivery. In the described case, apply governed versioning and validate the actual target scope before deployment resolves the identified control gap. Confirm with: Change records identify the approved template version and affected access point population.

Incorrect Answers

A:

This is relevant to a separate mist configuration objects and inheritance problem: An administrator creates a new WLAN object but never associates it with the appropriate site or WLAN template. It does not directly address this incident, which instead calls for: Apply governed versioning and validate the actual target scope before deployment.

C:

This is relevant to a separate mist configuration objects and inheritance problem: A site policy makes changes after an AP has gone offline, but operators assume the device has immediately received every update. It does not directly address this incident, which instead calls for: Apply governed versioning and validate the actual target scope before deployment.

D:

This is relevant to a separate mist configuration objects and inheritance problem: A WLAN template uses a static VLAN identifier that is different at two physical campuses. It does not directly address this incident, which instead calls for: Apply governed versioning and validate the actual target scope before deployment.

Question 728

A VoIP fleet uses robust low-rate modulation yet voice packet loss persists because the shared channel is saturated. Which action should the specialist recommend FIRST?

  1. Distinguish spatial multiplexing from QAM constellation and coding capabilities
  2. Inspect retries and quality-driven rate adaptation before diagnosing the driver
  3. Investigate MAC contention separately from modulation robustness when identifying the bottleneck
  4. Compare client coding capability, bandwidth, resource scheduling and negotiated radio conditions

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, investigate MAC contention separately from modulation robustness when identifying the bottleneck resolves the identified control gap. Confirm with: Channel busy time explains missed voice frames even as the selected robust MCS remains stable.

Incorrect Answers

A:

This is relevant to a separate modulation, coding and phy rates problem: An engineer confuses modulation order with antenna count and claims adding a spatial stream automatically produces 4096-QAM. It does not directly address this incident, which instead calls for: Investigate MAC contention separately from modulation robustness when identifying the bottleneck.

B:

This is relevant to a separate modulation, coding and phy rates problem: A WLAN engineer sees a client using a lower MCS during interference and assumes the wireless driver is defective. It does not directly address this incident, which instead calls for: Investigate MAC contention separately from modulation robustness when identifying the bottleneck.

D:

This is relevant to a separate modulation, coding and phy rates problem: An auditor concludes that two access points supporting 802.11ax necessarily give all associated devices identical PHY efficiency. It does not directly address this incident, which instead calls for: Investigate MAC contention separately from modulation robustness when identifying the bottleneck.

Question 729

An MSP exports Wi-Fi location trails for every organization without checking the recipient's permission to view person-related records. What corrective step most directly addresses the wireless fault?

  1. Restrict location data export by organization scope, purpose and authorized access roles
  2. Revalidate the location model under the actual supported radio configuration
  3. Update AP physical placement and recalibrate the site location map before relying on position estimates
  4. Complete site and floorplan AP positioning before interpreting wireless client location

Explanation

Correct Answer

A:

Wi-Fi location estimates require mapped APs, realistic uncertainty, appropriate time context and privacy-aware interpretation. In the described case, restrict location data export by organization scope, purpose and authorized access roles resolves the identified control gap. Confirm with: A receiving analyst sees only approved devices and events for the designated tenant.

Incorrect Answers

B:

This is relevant to a separate wi-fi location and mapping problem: A campus draws conclusions from Wi-Fi RSSI location information despite changing AP transmit-power and antenna settings during the survey. It does not directly address this incident, which instead calls for: Restrict location data export by organization scope, purpose and authorized access roles.

C:

This is relevant to a separate wi-fi location and mapping problem: A campus relocates access points but keeps their old floorplan coordinates, causing all Wi-Fi location estimates to drift. It does not directly address this incident, which instead calls for: Restrict location data export by organization scope, purpose and authorized access roles.

D:

This is relevant to a separate wi-fi location and mapping problem: A hospital tries to locate Wi-Fi devices across two buildings but one building has incomplete AP mapping and no reliable floor metadata. It does not directly address this incident, which instead calls for: Restrict location data export by organization scope, purpose and authorized access roles.

Question 730

An engineer says service analytics are not available for a locally bridged WLAN because no user packets are sent to the public cloud. What should the engineer investigate or configure next?

  1. Verify AP management-plane connectivity and WLAN client forwarding independently
  2. Design tenant-level organization isolation with explicit administrator and API identity boundaries
  3. Validate the supported AP telemetry path separately from client user-data forwarding
  4. Assess end-to-end WLAN service availability including wired uplinks, address servers and access identity systems

Explanation

Correct Answer

C:

Mist cloud control and observability are distinct from selected local or tunneled WLAN user-data forwarding paths. In the described case, validate the supported AP telemetry path separately from client user-data forwarding resolves the identified control gap. Confirm with: Mist monitoring receives permissible connection metrics while client traffic remains on the local network.

Incorrect Answers

A:

This is relevant to a separate cloud-managed wlan architecture and traffic paths problem: A site engineer equates AP cloud registration with proof that its physical uplink supports the intended client VLANs. It does not directly address this incident, which instead calls for: Validate the supported AP telemetry path separately from client user-data forwarding.

B:
