Mist AI Wireless, Specialist (JNCIS-MistAI-Wireless) JN0-452 Practice Test 20

Question 190

A warehouse client has strong RSSI but its successful connection percentage falls sharply during a RADIUS outage. The intended correction is: Investigate the Successful Connects authorization classifier rather than channel coverage. What is the best acceptance test for this change?

  1. The dashboard separates actual user attempts from AP Health availability measurements
  2. Client and EAP events show authorization failures during the service interruption
  3. The incident report assigns actual contributing airtime causes using measured evidence
  4. The SLE correctly flags completed but excessively slow connections as below target

Explanation

Correct Answer

B:

Client and EAP events show authorization failures during the service interruption directly tests the proposed corrective action: Investigate the Successful Connects authorization classifier rather than channel coverage. Wireless SLEs measure defined client-experience success and classifiers; different metrics and denominators are not interchangeable.

Incorrect Answers

A:

This check instead concerns a separate case: 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. Here the selected action should produce: Client and EAP events show authorization failures during the service interruption.

C:

That evidence would establish success in a different scenario: An RF team uses Capacity SLE deterioration alone to blame non-Wi-Fi interference without examining classifier breakdown. Here the selected action should produce: Client and EAP events show authorization failures during the service interruption.

D:

That observation would confirm another situation: An operator sets a five-second connection threshold and then claims success because all users eventually connected in fifteen seconds. Here the selected action should produce: Client and EAP events show authorization failures during the service interruption.

Question 191

An international company uses the same geographic address for two Mist sites and asset location results appear on the wrong floorplan. The selected operator action is: Correct the site record and floorplan association before accepting the location deployment. Which postchange finding most directly validates the action?

  1. The site inventory includes the AP and it advertises the approved service SSIDs
  2. Observed tags and AP positions align to the actual building map after correction
  3. AP inventory and incident timestamps display correct campus-specific site metadata
  4. A consolidated view lists each building while local VLAN and RF differences are preserved

Explanation

Correct Answer

B:

Observed tags and AP positions align to the actual building map after correction directly tests the proposed corrective action: Correct the site record and floorplan association before accepting the location deployment. Mist organizations provide ownership boundaries while sites represent actual locations with correct device membership and metadata.

Incorrect Answers

A:

That evidence would establish success in a different scenario: An access point is correctly claimed to an organization but remains unassigned to a physical site and receives no WLAN template. Here the selected action should produce: Observed tags and AP positions align to the actual building map after correction.

C:

That observation would confirm another situation: A university maps three campuses into one Mist site despite different country settings, time zones and local policy boundaries. Here the selected action should produce: Observed tags and AP positions align to the actual building map after correction.

D:

This check instead concerns a separate case: 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: Observed tags and AP positions align to the actual building map after correction.

Question 192

An AP has a management address but its DNS resolver cannot translate the assigned regional Mist service hostname. The recommended remediation is: Repair DNS resolution for the AP management path without changing client WLAN encryption. What evidence most clearly distinguishes success from a partial fix?

  1. The device reports online in Mist while unsolicited Internet management traffic stays blocked
  2. The AP resolves the correct endpoint and establishes its authorized management session
  3. A compatible powered port runs the AP under full radio load without repeated brownout
  4. The AP connects to the cloud and test clients reach their correct local network segment

Explanation

Correct Answer

B:

The AP resolves the correct endpoint and establishes its authorized management session directly tests the proposed corrective action: Repair DNS resolution for the AP management path without changing client WLAN encryption. Mist AP onboarding depends on local addressing, power, DNS, time, outbound management reachability and intended WLAN policy.

Incorrect Answers

A:

That observation would confirm another situation: A staging firewall allows inbound SSH to all APs yet denies the device-initiated TLS connection needed by cloud management. Here the selected action should produce: The AP resolves the correct endpoint and establishes its authorized management session.

C:

This check instead concerns a separate case: A newly installed access point is powered from an old PoE switch port and reboots whenever both radios activate. Here the selected action should produce: The AP resolves the correct endpoint and establishes its authorized management session.

D:

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: The AP resolves the correct endpoint and establishes its authorized management session.

Question 193

An API dashboard reads only the first response page and falsely reports that half the AP fleet is missing. The change request proposes: Follow the documented collection pagination and filter semantics for Mist resources. Which outcome should the site engineer expect after the repair?

  1. Rerunning a failed transaction yields exactly one intended site with the stable identifier
  2. The accepted request stores the correct typed settings and a GET returns the intended values
  3. A complete authorized inventory query matches the corresponding portal count across all pages
  4. The intended WLAN object is current and an online AP confirms the applied policy revision

Explanation

Correct Answer

C:

A complete authorized inventory query matches the corresponding portal count across all pages directly tests the proposed corrective action: Follow the documented collection pagination and filter semantics for Mist resources. Mist API operations require the supported method, region, stable resource identity, scoped credentials and post-write readback.

Incorrect Answers

A:

This check instead concerns a separate case: A deployment script creates duplicate Mist sites whenever it retries a POST after a delayed response. Here the selected action should produce: A complete authorized inventory query matches the corresponding portal count across all pages.

B:

That evidence would establish success in a different scenario: A script sends JSON properties with incompatible types and receives schema validation errors from the cloud service. Here the selected action should produce: A complete authorized inventory query matches the corresponding portal count across all pages.

D:

That observation would confirm another situation: An integration assumes a successful HTTP request response means an AP has already applied the new configuration. Here the selected action should produce: A complete authorized inventory query matches the corresponding portal count across all pages.

Question 194

An engineer copies a WPA2-PSK only profile to 6 GHz and new Wi-Fi 6E clients refuse to associate. The site engineer plans to: Select a supported 6 GHz security mode consistent with applicable WPA3 requirements. What observation would justify marking this case resolved?

  1. A rogue authentication endpoint is rejected and authorized logins follow approved policy
  2. The authorized casting workflow works while guest-to-guest scanning remains restricted
  3. Managed laptops complete trusted authentication without relaxing required certificate validation
  4. A certified-capable client joins the 6 GHz WLAN using the permitted robust security exchange

Explanation

Correct Answer

D:

A certified-capable client joins the 6 GHz WLAN using the permitted robust security exchange directly tests the proposed corrective action: Select a supported 6 GHz security mode consistent with applicable WPA3 requirements. Wireless security requires supported link encryption, trusted identity/certificates and least-privilege authorization beyond naming an SSID.

Incorrect Answers

A:

That evidence would establish success in a different scenario: An enterprise uses PEAP with weak passwords and treats the outer TLS tunnel as proof that credential phishing is impossible. Here the selected action should produce: A certified-capable client joins the 6 GHz WLAN using the permitted robust security exchange.

B:

That observation would confirm another situation: A team disables wireless client isolation to support one casting device and unintentionally enables lateral traffic among hundreds of guests. Here the selected action should produce: A certified-capable client joins the 6 GHz WLAN using the permitted robust security exchange.

C:

This check instead concerns a separate case: A university's network profile uses outdated EAP cipher choices and rejects modern clients that require stricter TLS behavior. Here the selected action should produce: A certified-capable client joins the 6 GHz WLAN using the permitted robust security exchange.

Question 195

An office interprets momentary movement past a doorway as a lengthy visitor encounter because the minimum encounter duration is unset. The incident lead approves this next step: Choose a supported minimum encounter duration appropriate to the occupancy analysis. Which observation best confirms the correction worked?

  1. A device entering and leaving the zone produces correctly ordered in and out events
  2. The report counts the designated tracked population within the actual permitted service zones
  3. A brief pass is excluded and a sustained authorized test visit appears with its correct duration
  4. The evaluation names equivalent spatial and time criteria with comparable occupancy observations

Explanation

Correct Answer

C:

A brief pass is excluded and a sustained authorized test visit appears with its correct duration directly tests the proposed corrective action: Choose a supported minimum encounter duration appropriate to the occupancy analysis. Proximity tracing depends on permitted zone definitions, client sources, RSSI thresholds, encounter duration and privacy controls.

Incorrect Answers

A:

That observation would confirm another situation: A facility configures zone entry on an RSSI threshold but omits exit event handling, so occupancy never decreases. Here the selected action should produce: A brief pass is excluded and a sustained authorized test visit appears with its correct duration.

B:

This check instead concerns a separate case: A retailer's proximity report includes passive neighboring devices outside the intended store zones and inflates occupancy counts. Here the selected action should produce: A brief pass is excluded and a sustained authorized test visit appears with its correct duration.

D:

That evidence would establish success in a different scenario: An engineer compares proximity dwell reports from two sites that use incompatible zone sizes and different encounter intervals. Here the selected action should produce: A brief pass is excluded and a sustained authorized test visit appears with its correct duration.

Question 196

An executive asks which sites were affected by last night's DHCP outage but the analyst exports an unfiltered organization-wide usage chart. The intended correction is: Filter Mist Insights by service classifier, affected sites and the exact outage interval. What evidence should be required before closing the incident?

  1. The root-cause record identifies the uplink reset and the resulting WLAN client failures
  2. A report identifies impacted branches and the associated DHCP attempts rather than overall traffic volume
  3. The outcome quantifies the target clients' transition improvement without mixing unrelated sites
  4. The analysis identifies whether clients actually left or access points stopped reporting

Explanation

Correct Answer

B:

A report identifies impacted branches and the associated DHCP attempts rather than overall traffic volume directly tests the proposed corrective action: Filter Mist Insights by service classifier, affected sites and the exact outage interval. Mist Insights need correct site, AP, client and time context and fresh telemetry to establish the real affected population.

Incorrect Answers

A:

This check instead concerns a separate case: A network engineer reviews an AP's event timeline but overlooks a simultaneous switch uplink reset that preceded all client disconnections. Here the selected action should produce: A report identifies impacted branches and the associated DHCP attempts rather than overall traffic volume.

C:

That evidence would establish success in a different scenario: A site owner wants proof that a roaming tuning change helped but the analysis compares devices in dissimilar buildings. Here the selected action should produce: A report identifies impacted branches and the associated DHCP attempts rather than overall traffic volume.

D:

That observation would confirm another situation: A site owner sees a steep decline in active-client counts and celebrates improved WLAN efficiency without checking offline AP inventory. Here the selected action should produce: A report identifies impacted branches and the associated DHCP attempts rather than overall traffic volume.

Question 197

A building wants to find tagged equipment but enables only AP-transmitted vBLE beams intended for phone-based wayfinding. The selected operator action is: Enable Asset Visibility reception with compatible BLE tags and the required entitlement. Which result would demonstrate the intended network outcome?

  1. Engagement messages and asset-tag observations both succeed within supported service limits
  2. A controlled BLE walk test shows improved location estimates along the target corridor
  3. Representative users receive the expected beacon signal in each designated service zone
  4. A named test tag appears in the correct Asset Visibility location view

Explanation

Correct Answer

D:

A named test tag appears in the correct Asset Visibility location view directly tests the proposed corrective action: Enable Asset Visibility reception with compatible BLE tags and the required entitlement. 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: 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: A named test tag appears in the correct Asset Visibility location view.

B:

That observation would confirm another situation: An installer places BLE-capable APs above a metal ceiling grid and the location map repeatedly identifies the wrong corridor. Here the selected action should produce: A named test tag appears in the correct Asset Visibility location view.

C:

This check instead concerns a separate case: 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: A named test tag appears in the correct Asset Visibility location view.

Question 198

A Marvis Mini reports DNS failure on a specific VLAN, but the technician replaces an AP radio without inspecting service dependencies. The recommended remediation is: Follow the synthetic validation stage to the actual DNS or network-path fault. What is the best acceptance test for this change?

  1. The relevant authorized synthetic-test view returns under a valid supported subscription
  2. A reporting matrix identifies which network contexts were tested and which still need validation
  3. A valid completed test returns current results without conflicting simultaneous executions
  4. A corrected resolver path yields successful DNS checks on the relevant VLAN

Explanation

Correct Answer

D:

A corrected resolver path yields successful DNS checks on the relevant VLAN directly tests the proposed corrective action: Follow the synthetic validation stage to the actual DNS or network-path fault. Marvis Minis is a synthetic network validation capability, not proof of every real client experience or unsupported service.

Incorrect Answers

A:

That observation would confirm another situation: A warehouse's Marvis Minis tests appear missing after a Marvis for Wireless subscription expires. Here the selected action should produce: A corrected resolver path yields successful DNS checks on the relevant VLAN.

B:

This check instead concerns a separate case: 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: A corrected resolver path yields successful DNS checks on the relevant VLAN.

C:

That evidence would establish success in a different scenario: A WLAN team enables on-demand Minis during a running automatic validation and assumes an overlapping request must work immediately. Here the selected action should produce: A corrected resolver path yields successful DNS checks on the relevant VLAN.

Question 199

A multinational NOC sends an ambiguous phrase translated from one language and receives results for the wrong site identifier. The change request proposes: Use a supported language and explicit unambiguous site or device identifiers in the query. Which postchange finding most directly validates the action?

  1. The answer shows separate prechange failures and recent validated client outcomes
  2. The case includes traceable measurements rather than an unsupported narrative assertion
  3. The assistant returns a scoped diagnostic explanation without silently changing production WLAN policy
  4. The returned diagnostic names the intended asset and remains within the authorized Mist tenant

Explanation

Correct Answer

D:

The returned diagnostic names the intended asset and remains within the authorized Mist tenant directly tests the proposed corrective action: Use a supported language and explicit unambiguous site or device identifiers in the query. Conversational Marvis queries should use supported language, clear network context, correct identities and evidence-aware interpretation.

Incorrect Answers

A:

This check instead concerns a separate case: A campus engineer asks Marvis about client connectivity after resetting the access point but does not specify whether the requested interval is before or after the reset. Here the selected action should produce: The returned diagnostic names the intended asset and remains within the authorized Mist tenant.

B:

That evidence would establish success in a different scenario: A field engineer interprets a Marvis conversational description as raw proof of every packet loss event without opening supporting telemetry. Here the selected action should produce: The returned diagnostic names the intended asset and remains within the authorized Mist tenant.

C:

That observation would confirm another situation: A help desk translates a technical WLAN request using an unsupported or ambiguous command phrase and assumes Marvis must execute a privileged configuration change. Here the selected action should produce: The returned diagnostic names the intended asset and remains within the authorized Mist tenant.

Question 200

A warehouse expects exact centimeter location from low-cost BLE tags that transmit only limited advertising information. The site engineer plans to: Set realistic zonal-accuracy acceptance criteria and validate positioning with known test tags. What evidence most clearly distinguishes success from a partial fix?

  1. A measured tracking exercise reports the actual supported location error without exaggerated precision
  2. After entitlement correction authorized tags return to the portal without unnecessary replacement
  3. A supported replacement tag broadcasts and the pump returns to named asset monitoring
  4. The Live View distinguishes each tested infusion pump rather than listing anonymous beacons

Explanation

Correct Answer

A:

A measured tracking exercise reports the actual supported location error without exaggerated precision directly tests the proposed corrective action: Set realistic zonal-accuracy acceptance criteria and validate positioning with known test tags. Asset Visibility uses compatible BLE tags, authorized reception, correct asset mapping and realistic zonal-accuracy expectations.

Incorrect Answers

B:

That evidence would establish success in a different scenario: A hospital's BLE asset tracking stops after its cloud service entitlement expires and staff blame the tags' batteries. Here the selected action should produce: A measured tracking exercise reports the actual supported location error without exaggerated precision.

C:

That observation would confirm another situation: A critical pump tag disappears from the dashboard after its battery is exhausted but nearby APs remain healthy. Here the selected action should produce: A measured tracking exercise reports the actual supported location error without exaggerated precision.

D:

This check instead concerns a separate case: A hospital attaches BLE tags to infusion pumps but never associates their identifiers with named inventory records. Here the selected action should produce: A measured tracking exercise reports the actual supported location error without exaggerated precision.
