Question 230

An engineer adjusts SLE settings after an outage but compares the new success percentage directly with an old threshold. The incident lead approves this next step: Document and normalize threshold changes before comparing performance across measurement periods. Which outcome should the site engineer expect after the repair?

  1. The audit displays the same underlying event set as both correct counts and rates
  2. Each threshold is attributable to a requirement and any revision is recorded before deployment
  3. The filtered results refer only to the affected guest sessions and appropriate service threshold
  4. The report identifies the old and new goals and avoids misrepresenting improved compliance as better radio health

Explanation

Correct Answer

D:

The report identifies the old and new goals and avoids misrepresenting improved compliance as better radio health directly tests the proposed corrective action: Document and normalize threshold changes before comparing performance across measurement periods. SLE thresholds must express documented user-service goals with transparent scope, denominator and change history.

Incorrect Answers

A:

That evidence would establish success in a different scenario: An engineer changes an SLE from Success Rate to Values and concludes that the metric suddenly improved by thousands of percent. Here the selected action should produce: The report identifies the old and new goals and avoids misrepresenting improved compliance as better radio health.

B:

That observation would confirm another situation: A wireless design has no documented reason for its selected coverage or throughput targets and teams continually change them after complaints. Here the selected action should produce: The report identifies the old and new goals and avoids misrepresenting improved compliance as better radio health.

C:

This check instead concerns a separate case: A branch site allows its Wireless Assurance view to aggregate unrelated SSIDs when only a guest WLAN is under investigation. Here the selected action should produce: The report identifies the old and new goals and avoids misrepresenting improved compliance as better radio health.

Question 231

An administrator disables protected management frames on a WPA3-only WLAN because legacy devices have trouble connecting. The intended correction is: Preserve supported PMF requirements and provide a separate compatible legacy service if justified. What observation would justify marking this case resolved?

  1. A rogue authentication endpoint is rejected and authorized logins follow approved policy
  2. Routine WLAN operators cannot export protected authentication secrets and all changes are attributed
  3. Modern clients negotiate protected management frames and approved legacy devices use the separate profile
  4. The protected transport comes up only for the appropriately authenticated trusted peer

Explanation

Correct Answer

C:

Modern clients negotiate protected management frames and approved legacy devices use the separate profile directly tests the proposed corrective action: Preserve supported PMF requirements and provide a separate compatible legacy service if justified. Wireless security requires supported link encryption, trusted identity/certificates and least-privilege authorization beyond naming an SSID.

Incorrect Answers

A:

That observation would confirm another situation: 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: Modern clients negotiate protected management frames and approved legacy devices use the separate profile.

B:

This check instead concerns a separate case: A branch uses the same administrative login for WLAN configuration and RADIUS credential access, leaving no separation of duties. Here the selected action should produce: Modern clients negotiate protected management frames and approved legacy devices use the separate profile.

D:

That evidence would establish success in a different scenario: An engineer configures RADIUS-over-TLS but one peer presents a certificate signed by an unknown issuing authority. Here the selected action should produce: Modern clients negotiate protected management frames and approved legacy devices use the separate profile.

Question 232

An operator assigns an 80 MHz channel in 5 GHz to every neighboring classroom AP without reviewing channel reuse. The selected operator action is: Use channel width and reuse decisions based on density, interference and available spectrum. Which observation best confirms the correction worked?

  1. Channel events explain the move and clients remain served through an acceptable alternative channel
  2. After replan adjacent cells have distinguishable channels and measured client contention falls
  3. The updated survey records real 6 GHz beacons and supported client RSSI along the target route
  4. The walk survey records actual received signals beyond the walls and identifies coverage gaps

Explanation

Correct Answer

B:

After replan adjacent cells have distinguishable channels and measured client contention falls directly tests the proposed corrective action: Use channel width and reuse decisions based on density, interference and available spectrum. Channel planning depends on supported frequency bands, local regulatory rules, widths and actual interference.

Incorrect Answers

A:

This check instead concerns a separate case: A new 5 GHz channel is selected in a radar-sensitive range and APs unexpectedly change frequency when radar is detected. Here the selected action should produce: After replan adjacent cells have distinguishable channels and measured client contention falls.

C:

That evidence would establish success in a different scenario: An engineer surveys a 6 GHz WLAN using a test laptop whose adapter can scan only 2.4 and 5 GHz and records zero service coverage. Here the selected action should produce: After replan adjacent cells have distinguishable channels and measured client contention falls.

D:

That observation would confirm another situation: A technician expects 5 GHz to propagate through reinforced concrete as well as 2.4 GHz at the same power. Here the selected action should produce: After replan adjacent cells have distinguishable channels and measured client contention falls.

Question 233

A technician asks Marvis to compare two clients but supplies only their shared display name rather than stable identities. The recommended remediation is: Specify distinct supported client identifiers and the same observation window. What evidence should be required before closing the incident?

  1. The supported diagnostic follows the specified 802.11 or service-layer condition rather than an ambiguous term
  2. The answer compares the correct two clients and their separate connection event histories
  3. The resulting diagnosis references the correct service and a manageable set of relevant events
  4. The returned diagnostic names the intended asset and remains within the authorized Mist tenant

Explanation

Correct Answer

B:

The answer compares the correct two clients and their separate connection event histories directly tests the proposed corrective action: Specify distinct supported client identifiers and the same observation window. Conversational Marvis queries should use supported language, clear network context, correct identities and evidence-aware interpretation.

Incorrect Answers

A:

That evidence would establish success in a different scenario: A network manager asks the assistant to interpret an acronym inconsistently across regions and receives an irrelevant troubleshooting path. Here the selected action should produce: The answer compares the correct two clients and their separate connection event histories.

C:

That observation would confirm another situation: A regional operator asks a broad query about poor Wi-Fi and gets several unrelated candidate issues. Here the selected action should produce: The answer compares the correct two clients and their separate connection event histories.

D:

This check instead concerns a separate case: A multinational NOC sends an ambiguous phrase translated from one language and receives results for the wrong site identifier. Here the selected action should produce: The answer compares the correct two clients and their separate connection event histories.

Question 234

A venue enables guest client isolation but visitors still reach employee servers through the site's unrestricted routing policy. The change request proposes: Combine WLAN client isolation with appropriate VLAN and upstream network access controls. Which result would demonstrate the intended network outcome?

  1. Guest devices cannot reach staff services while approved Internet connectivity continues
  2. A busy-hour voice test meets latency objectives while background transfers remain authorized
  3. The client receives an address on the intended subnet and reaches only approved company services
  4. Terminal battery tests improve without missing critical application notifications

Explanation

Correct Answer

A:

Guest devices cannot reach staff services while approved Internet connectivity continues directly tests the proposed corrective action: Combine WLAN client isolation with appropriate VLAN and upstream network access controls. SSID availability, client admission, VLAN segmentation, QoS and actual service reachability are separate WLAN properties.

Incorrect Answers

B:

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: Guest devices cannot reach staff services while approved Internet connectivity continues.

C:

This check instead concerns a separate case: An employee associates to the company SSID on an AP mapped to the wrong local VLAN and cannot reach the assigned application. Here the selected action should produce: Guest devices cannot reach staff services while approved Internet connectivity continues.

D:

That evidence would establish success in a different scenario: 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: Guest devices cannot reach staff services while approved Internet connectivity continues.

Question 235

An administrator edits a guest WLAN's captive portal option but forgets to enable the portal requirement on the applied WLAN. The site engineer plans to: Associate the guest portal configuration with the effective WLAN authentication workflow. What is the best acceptance test for this change?

  1. The surviving permitted WLANs retain correct access and the stale policy reference is absent
  2. Only lab APs advertise the new SSID and other sites show no unintended broadcast
  3. A fresh guest client receives the required redirect and permitted service after acceptance
  4. A capable 6 GHz client completes compliant security negotiation while legacy 5 GHz service remains separate

Explanation

Correct Answer

C:

A fresh guest client receives the required redirect and permitted service after acceptance directly tests the proposed corrective action: Associate the guest portal configuration with the effective WLAN authentication workflow. 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 fresh guest client receives the required redirect and permitted service after acceptance.

B:

That evidence would establish success in a different scenario: A company enables a WLAN in every site through an inherited template when only its pilot lab should advertise it. Here the selected action should produce: A fresh guest client receives the required redirect and permitted service after acceptance.

D:

That observation would confirm another situation: 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 fresh guest client receives the required redirect and permitted service after acceptance.

Question 236

A hospital enables mandatory 802.11r fast transition on a legacy device population that cannot complete FT handshakes. The incident lead approves this next step: Validate client FT interoperability and choose a compatible supported roaming configuration. Which postchange finding most directly validates the action?

  1. The capture identifies association success followed by the precise EAP or RADIUS failure stage
  2. The health report shows successful and failed handoffs with actual interruption durations
  3. Old clients complete roaming while newer fast-transition clients retain the intended behavior
  4. A valid roam completes without unnecessary new addressing while application traffic continues

Explanation

Correct Answer

C:

Old clients complete roaming while newer fast-transition clients retain the intended behavior directly tests the proposed corrective action: Validate client FT interoperability and choose a compatible supported roaming configuration. Association, EAP authorization, DHCP and roaming transitions are distinct stages with distinct evidence and failure modes.

Incorrect Answers

A:

That evidence would establish success in a different scenario: An operator confuses successful initial 802.11 association with completed 802.1X authorization on an enterprise WLAN. Here the selected action should produce: Old clients complete roaming while newer fast-transition clients retain the intended behavior.

B:

That observation would confirm another situation: A site evaluates roaming performance using only AP uptime and ignores each client's transition time. Here the selected action should produce: Old clients complete roaming while newer fast-transition clients retain the intended behavior.

D:

This check instead concerns a separate case: An engineer assumes every association request must complete a full DHCP lease exchange even when a permitted roam preserves client addressing. Here the selected action should produce: Old clients complete roaming while newer fast-transition clients retain the intended behavior.

Question 237

A team wants near-real-time AP outages but its integration fetches a complete historical report once daily. The intended correction is: Configure a supported event subscription and authorized webhook receiver for the relevant alerts. What evidence most clearly distinguishes success from a partial fix?

  1. The integration receives event POSTs while packet troubleshooting uses the supported diagnostic interface
  2. A controlled AP disconnect produces a timely notification to the correct operational system
  3. Unauthorized forged alert requests are rejected and a genuine test alert reaches the approved queue
  4. A notification appears only in its authorized customer's incident view and data partition

Explanation

Correct Answer

B:

A controlled AP disconnect produces a timely notification to the correct operational system directly tests the proposed corrective action: Configure a supported event subscription and authorized webhook receiver for the relevant alerts. Event-driven webhook delivery needs authorized receivers, scoped event context, safe retries and reliable processing.

Incorrect Answers

A:

That observation would confirm another situation: A developer assumes a webhook can stream raw packet-capture frames continuously over a two-way open session. Here the selected action should produce: A controlled AP disconnect produces a timely notification to the correct operational system.

C:

This check instead concerns a separate case: A Mist monitoring integration treats every incoming POST as trusted without validating sender credentials or request origin. Here the selected action should produce: A controlled AP disconnect produces a timely notification to the correct operational system.

D:

That evidence would establish success in a different scenario: An MSP processes multiple customers' webhooks in the same unpartitioned queue and exposes device identities across tenants. Here the selected action should produce: A controlled AP disconnect produces a timely notification to the correct operational system.

Question 238

A campus relocates access points but keeps their old floorplan coordinates, causing all Wi-Fi location estimates to drift. The selected operator action is: Update AP physical placement and recalibrate the site location map before relying on position estimates. Which outcome should the site engineer expect after the repair?

  1. A representative walk trace follows the correct floor and reports realistic uncertainty for the tracked device
  2. Known test device locations align with the updated floor plan within the supported service tolerance
  3. A test device's building and floor estimates match its verified physical route
  4. A field test identifies true zone visits without claiming centimeter-level precision

Explanation

Correct Answer

B:

Known test device locations align with the updated floor plan within the supported service tolerance directly tests the proposed corrective action: Update AP physical placement and recalibrate the site location map before relying on position estimates. Wi-Fi location estimates require mapped APs, realistic uncertainty, appropriate time context and privacy-aware interpretation.

Incorrect Answers

A:

This check instead concerns a separate case: 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. Here the selected action should produce: Known test device locations align with the updated floor plan within the supported service tolerance.

C:

That evidence would establish success in a different scenario: A hospital tries to locate Wi-Fi devices across two buildings but one building has incomplete AP mapping and no reliable floor metadata. Here the selected action should produce: Known test device locations align with the updated floor plan within the supported service tolerance.

D:

That observation would confirm another situation: A warehouse wants to use Wi-Fi location records to determine whether scanners visited a restricted loading area. Here the selected action should produce: Known test device locations align with the updated floor plan within the supported service tolerance.

Question 239

A help desk interprets a Wi-Fi interferer alert as proof that the device is a malicious rogue AP. The recommended remediation is: Differentiate RF interference from an unauthorized infrastructure device before assigning security severity. What observation would justify marking this case resolved?

  1. A test unauthorized hotspot is located and handled without blocking approved neighboring business networks
  2. The classification report separates coincidental neighboring networks from actual enterprise impersonation
  3. An inspection identifies the emitter and categorizes its security relevance using appropriate evidence
  4. A rogue attempt is detected while test devices independently reject untrusted authentication exchanges

Explanation

Correct Answer

C:

An inspection identifies the emitter and categorizes its security relevance using appropriate evidence directly tests the proposed corrective action: Differentiate RF interference from an unauthorized infrastructure device before assigning security severity. Wireless intrusion monitoring requires evidence-based classification of rogue, interfering and authorized devices and bounded response.

Incorrect Answers

A:

That evidence would establish success in a different scenario: An enterprise permits unsanctioned personal hotspots in a sensitive clinical zone and relies only on a global SSID blacklist. Here the selected action should produce: An inspection identifies the emitter and categorizes its security relevance using appropriate evidence.

B:

That observation would confirm another situation: An AP hears a neighboring company WLAN using the same SSID but operations automatically labels it malicious without checking physical or ownership context. Here the selected action should produce: An inspection identifies the emitter and categorizes its security relevance using appropriate evidence.

D:

This check instead concerns a separate case: A wireless team assumes intrusion prevention eliminates the need for protected management frames and certificate validation on clients. Here the selected action should produce: An inspection identifies the emitter and categorizes its security relevance using appropriate evidence.

Question 240

A warehouse's Roaming SLE drops only when barcode terminals move past shelving at one location. The change request proposes: Correlate handoff events, cell overlap and client capability near the affected aisle. Which observation best confirms the correction worked?

  1. A RADIUS timing test restores connection delay beneath the approved threshold
  2. The moving scanner completes transitions without the previously observed repeated disconnects
  3. Uplink negotiation and effective client throughput rise after the supported wired fix
  4. A reconciled report includes disconnected devices and shows the actual service-health trend

Explanation

Correct Answer

B:

The moving scanner completes transitions without the previously observed repeated disconnects directly tests the proposed corrective action: Correlate handoff events, cell overlap and client capability near the affected aisle. SLE troubleshooting links the selected failed classifier to real client and upstream dependency evidence before changing infrastructure.

Incorrect Answers

A:

That observation would confirm another situation: An office Time to Connect SLE is low because the AP receives authentication responses slowly, but users eventually connect. Here the selected action should produce: The moving scanner completes transitions without the previously observed repeated disconnects.

C:

This check instead concerns a separate case: A classroom shows low Throughput SLE while every device still has adequate coverage and a 100 Mbps AP wired uplink is saturated. Here the selected action should produce: The moving scanner completes transitions without the previously observed repeated disconnects.

D:

That evidence would establish success in a different scenario: An enterprise SLE reports improved success after all impaired clients disconnect, shrinking the observation population. Here the selected action should produce: The moving scanner completes transitions without the previously observed repeated disconnects.
