Mist AI Wireless, Specialist (JNCIS-MistAI-Wireless) JN0-452 Practice Test 35

Question 340

A store has excellent AP Health but customers report poor wireless capacity during the lunch rush. The recommended remediation is: Compare RF Capacity and client Throughput SLEs with AP availability separately. What observation would justify marking this case resolved?

  1. Port-specific Ethernet evidence explains the affected AP's failure without equating green global scores to all-up
  2. Wired interface negotiation and throughput measurements expose the upstream bottleneck
  3. The SLE correctly flags completed but excessively slow connections as below target
  4. Busy-hour capacity classifiers show airtime contention despite available access points

Explanation

Correct Answer

D:

Busy-hour capacity classifiers show airtime contention despite available access points directly tests the proposed corrective action: Compare RF Capacity and client Throughput SLEs with AP availability separately. 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: A remote site has a green AP Health SLE but one unplugged switch port disrupts staff on a single radio. Here the selected action should produce: Busy-hour capacity classifiers show airtime contention despite available access points.

B:

That evidence would establish success in a different scenario: A client RSSI improves after AP relocation, yet application throughput remains low because the wired uplink is limited to 100 Mbps. Here the selected action should produce: Busy-hour capacity classifiers show airtime contention despite available access points.

C:

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: Busy-hour capacity classifiers show airtime contention despite available access points.

Question 341

A warehouse scanner loses service only when moving from one AP to another while stationary signal is sufficient. The change request proposes: Analyze roaming events and mobility policy compatibility across the source and destination APs. Which observation best confirms the correction worked?

  1. DHCP exchanges succeed on the correct subnet after the authorized mapping repair
  2. The AP advertises the campus SSID and the valid student completes association and authentication
  3. The retired network is no longer advertised and other SSIDs remain unchanged
  4. Handoff evidence isolates the failing transition and application connectivity remains stable after repair

Explanation

Correct Answer

D:

Handoff evidence isolates the failing transition and application connectivity remains stable after repair directly tests the proposed corrective action: Analyze roaming events and mobility policy compatibility across the source and destination APs. Wireless faults should be isolated at the actual RF, association, authorization, DHCP, policy or application stage.

Incorrect Answers

A:

That evidence would establish success in a different scenario: A corporate client associates to an SSID but cannot obtain an IP address after a VLAN mapping change. Here the selected action should produce: Handoff evidence isolates the failing transition and application connectivity remains stable after repair.

B:

That observation would confirm another situation: 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: Handoff evidence isolates the failing transition and application connectivity remains stable after repair.

C:

This check instead concerns a separate case: An engineer removes an SSID from a site WLAN object but it remains visible because an inherited template still applies. Here the selected action should produce: Handoff evidence isolates the failing transition and application connectivity remains stable after repair.

Question 342

A Mist site has both local WLAN settings and an organization template, and operators cannot explain which parameters take effect. The site engineer plans to: Inspect the supported configuration precedence and the resulting device configuration. What evidence should be required before closing the incident?

  1. An AP configuration readback shows the actual inherited and overridden WLAN parameters
  2. An inventory export maps the target AP to the unique intended WLAN object
  3. The returning AP reports the current approved profile and a client test validates actual service
  4. All dependent APs have migrated to a supported replacement before the object is removed

Explanation

Correct Answer

A:

An AP configuration readback shows the actual inherited and overridden WLAN parameters directly tests the proposed corrective action: Inspect the supported configuration precedence and the resulting device configuration. Reusable Mist configuration objects require correct references, inheritance, target membership and verified device delivery.

Incorrect Answers

B:

That observation would confirm another situation: A technician creates multiple WLAN objects with the same display name and cannot identify which one is bound to the AP template. Here the selected action should produce: An AP configuration readback shows the actual inherited and overridden WLAN parameters.

C:

This check instead concerns a separate case: A site policy makes changes after an AP has gone offline, but operators assume the device has immediately received every update. Here the selected action should produce: An AP configuration readback shows the actual inherited and overridden WLAN parameters.

D:

That evidence would establish success in a different scenario: An engineer deletes a network profile in use by several production access points, causing unexpected service loss. Here the selected action should produce: An AP configuration readback shows the actual inherited and overridden WLAN parameters.

Question 343

A branch identifies an evil-twin SSID but analysts never compare the fake authentication portal with the approved server certificate. The incident lead approves this next step: Investigate unauthorized SSID and authentication server identity together using WIDS evidence. Which result would demonstrate the intended network outcome?

  1. Incident evidence links actual affected connections to relevant threat events rather than coincidental alarms
  2. A controlled rogue event creates a traceable security case with responsible responders
  3. The attack simulation identifies the fraudulent transmitter and a managed client rejects its false identity
  4. A controlled test prevents unauthorized broad deauthentication while approved managed security responses remain possible

Explanation

Correct Answer

C:

The attack simulation identifies the fraudulent transmitter and a managed client rejects its false identity directly tests the proposed corrective action: Investigate unauthorized SSID and authentication server identity together using WIDS evidence. Wireless intrusion monitoring requires evidence-based classification of rogue, interfering and authorized devices and bounded response.

Incorrect Answers

A:

This check instead concerns a separate case: A campus receives frequent WIPS events during a conference but no analyst checks whether the timestamps align with the reported client failures. Here the selected action should produce: The attack simulation identifies the fraudulent transmitter and a managed client rejects its false identity.

B:

That evidence would establish success in a different scenario: A WIDS deployment detects rogue devices but never forwards actionable high-severity findings to the security response team. Here the selected action should produce: The attack simulation identifies the fraudulent transmitter and a managed client rejects its false identity.

D:

That observation would confirm another situation: An engineer enables automatic containment against every neighboring Wi-Fi network and disrupts legitimate third-party users. Here the selected action should produce: The attack simulation identifies the fraudulent transmitter and a managed client rejects its false identity.

Question 344

A shopping mall's asset map shows tagged carts on the wrong floor after an AP was moved during construction. The intended correction is: Correct AP placement and floorplan metadata before accepting the tag location result. What is the best acceptance test for this change?

  1. Known cart-tag locations map to the revised physical floor accurately enough for the service
  2. A measured tracking exercise reports the actual supported location error without exaggerated precision
  3. The Live View distinguishes each tested infusion pump rather than listing anonymous beacons
  4. A supported replacement tag broadcasts and the pump returns to named asset monitoring

Explanation

Correct Answer

A:

Known cart-tag locations map to the revised physical floor accurately enough for the service directly tests the proposed corrective action: Correct AP placement and floorplan metadata before accepting the tag location result. 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 warehouse expects exact centimeter location from low-cost BLE tags that transmit only limited advertising information. Here the selected action should produce: Known cart-tag locations map to the revised physical floor accurately enough for the service.

C:

That observation would confirm another situation: A hospital attaches BLE tags to infusion pumps but never associates their identifiers with named inventory records. Here the selected action should produce: Known cart-tag locations map to the revised physical floor accurately enough for the service.

D:

This check instead concerns a separate case: A critical pump tag disappears from the dashboard after its battery is exhausted but nearby APs remain healthy. Here the selected action should produce: Known cart-tag locations map to the revised physical floor accurately enough for the service.

Question 345

A campus enables a virtual BLE array only on one AP but expects continuous location guidance throughout several separate floors. The selected operator action is: Plan appropriate supported AP coverage and enable vBLE on the required device population. Which postchange finding most directly validates the action?

  1. A controlled BLE walk test shows improved location estimates along the target corridor
  2. A representative phone test locates known points using the current AP map rather than obsolete positions
  3. A named test tag appears in the correct Asset Visibility location view
  4. Representative users receive the expected beacon signal in each designated service zone

Explanation

Correct Answer

D:

Representative users receive the expected beacon signal in each designated service zone directly tests the proposed corrective action: Plan appropriate supported AP coverage and enable vBLE on the required device population. vBLE Engagement transmits positioning beacons while Asset Visibility listens for BLE tag advertisements; mapping and hardware matter.

Incorrect Answers

A:

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: Representative users receive the expected beacon signal in each designated service zone.

B:

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: Representative users receive the expected beacon signal in each designated service zone.

C:

That evidence would establish success in a different scenario: A building wants to find tagged equipment but enables only AP-transmitted vBLE beams intended for phone-based wayfinding. Here the selected action should produce: Representative users receive the expected beacon signal in each designated service zone.

Question 346

A retail site uses a Mist organization for all regional customers despite contractual separation of configuration and user records. The recommended remediation is: Design tenant-level organization isolation with explicit administrator and API identity boundaries. What evidence most clearly distinguishes success from a partial fix?

  1. Cross-tenant access tests deny unrelated customer data while authorized per-organization operations succeed
  2. A controlled management outage documents the surviving client forwarding and any unavailable management features
  3. The staging acceptance test follows successful power-up, addressing, DNS and cloud onboarding
  4. Test client packets traverse the required firewall path only when the intended forwarding mode is applied

Explanation

Correct Answer

A:

Cross-tenant access tests deny unrelated customer data while authorized per-organization operations succeed directly tests the proposed corrective action: Design tenant-level organization isolation with explicit administrator and API identity boundaries. Mist cloud control and observability are distinct from selected local or tunneled WLAN user-data forwarding paths.

Incorrect Answers

B:

This check instead concerns a separate case: An enterprise expects wireless service to lose its complete dataplane instantly whenever its Mist management portal is unreachable. Here the selected action should produce: Cross-tenant access tests deny unrelated customer data while authorized per-organization operations succeed.

C:

That evidence would establish success in a different scenario: A branch deploys a new Mist-managed AP without identifying the role of DNS, DHCP and external cloud reachability in onboarding. Here the selected action should produce: Cross-tenant access tests deny unrelated customer data while authorized per-organization operations succeed.

D:

That observation would confirm another situation: A client SSID is configured for local bridge but the firewall team expects to enforce all its traffic at Mist Edge in a distant DMZ. Here the selected action should produce: Cross-tenant access tests deny unrelated customer data while authorized per-organization operations succeed.

Question 347

A campus changes all access points simultaneously and loses the ability to isolate whether the fault came from firmware or policy. The change request proposes: Stage WLAN changes with controlled scope, documented rollback and version comparison. Which outcome should the site engineer expect after the repair?

  1. Payment devices sustain approved transactions and the previous path remains available until acceptance
  2. Post-renovation RF evidence supports the new AP locations and client experience objectives
  3. Quarterly evidence identifies changed load and validates revised coverage or channel policy
  4. The pilot identifies the faulty change and rollback restores user service without a sitewide outage

Explanation

Correct Answer

D:

The pilot identifies the faulty change and rollback restores user service without a sitewide outage directly tests the proposed corrective action: Stage WLAN changes with controlled scope, documented rollback and version comparison. The WLAN lifecycle includes requirements, RF survey, compatibility, staged deployment, client acceptance, operation and controlled retirement.

Incorrect Answers

A:

That evidence would establish success in a different scenario: A WLAN team migrates to a new SSID without preserving a rollback option for payment handsets used around the clock. Here the selected action should produce: The pilot identifies the faulty change and rollback restores user service without a sitewide outage.

B:

That observation would confirm another situation: An office reuses a radio plan after extensive construction adds metal partitions and new meeting rooms. Here the selected action should produce: The pilot identifies the faulty change and rollback restores user service without a sitewide outage.

C:

This check instead concerns a separate case: A company runs a year-long WLAN without periodic RF review despite growing device density and new neighboring networks. Here the selected action should produce: The pilot identifies the faulty change and rollback restores user service without a sitewide outage.

Question 348

A WLAN's Coverage SLE drops sharply after access points are moved behind new metal partitions. The site engineer plans to: Perform RF measurements of the altered obstruction and correct AP location or antenna orientation. What observation would justify marking this case resolved?

  1. The case identifies the failing roam stage and confirms improvement after a targeted fix
  2. A test managed client completes enterprise authentication after the actual RADIUS issue is corrected
  3. Uplink negotiation and effective client throughput rise after the supported wired fix
  4. An updated walk survey shows restored received signal along the affected work route

Explanation

Correct Answer

D:

An updated walk survey shows restored received signal along the affected work route directly tests the proposed corrective action: Perform RF measurements of the altered obstruction and correct AP location or antenna orientation. 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 engineer responds to a Wi-Fi Roaming SLE failure by rebooting a cloud management portal instead of checking client handoff timelines. Here the selected action should produce: An updated walk survey shows restored received signal along the affected work route.

B:

This check instead concerns a separate case: A hospital's Successful Connects SLE falls following a RADIUS configuration update, while AP RSSI remains strong. Here the selected action should produce: An updated walk survey shows restored received signal along the affected work route.

C:

That evidence would establish success in a different scenario: 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: An updated walk survey shows restored received signal along the affected work route.

Question 349

A company grants privileged production network access whenever a device presents any certificate signed by an unrelated public CA. The intended correction is: Restrict accepted EAP-TLS client certificates to approved trust anchors and policy identity requirements. What is the best acceptance test for this change?

  1. A corporate device succeeds and a nonmember certificate cannot acquire the privileged VLAN
  2. A rogue authentication endpoint is rejected and authorized logins follow approved policy
  3. The test client rejects protected-frame spoofing where the selected standard and devices support PMF
  4. A compliance test documents the Wi-Fi cipher and the separate authorized portal behavior

Explanation

Correct Answer

A:

A corporate device succeeds and a nonmember certificate cannot acquire the privileged VLAN directly tests the proposed corrective action: Restrict accepted EAP-TLS client certificates to approved trust anchors and policy identity requirements. Wireless security requires supported link encryption, trusted identity/certificates and least-privilege authorization beyond naming an SSID.

Incorrect Answers

B:

This check instead concerns a separate case: 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 corporate device succeeds and a nonmember certificate cannot acquire the privileged VLAN.

C:

That evidence would establish success in a different scenario: A medical AP receives deauthentication frames from a spoofed address and the team assumes WPA2 encryption protects every management message. Here the selected action should produce: A corporate device succeeds and a nonmember certificate cannot acquire the privileged VLAN.

D:

That observation would confirm another situation: A school allows any device to join a staff SSID using a captive portal login while assuming the portal encrypts all pre-portal radio traffic. Here the selected action should produce: A corporate device succeeds and a nonmember certificate cannot acquire the privileged VLAN.

Question 350

An engineer creates a Mist site without setting the appropriate country and the AP cannot use the required legal wireless channels. The selected operator action is: Correct site country and operating metadata to match the physical installation. Which postchange finding most directly validates the action?

  1. The old site has no live dependencies and authorized alert routing remains functional
  2. AP inventory and incident timestamps display correct campus-specific site metadata
  3. The AP selects permitted channels and the site record matches documented installation coordinates
  4. The site inventory includes the AP and it advertises the approved service SSIDs

Explanation

Correct Answer

C:

The AP selects permitted channels and the site record matches documented installation coordinates directly tests the proposed corrective action: Correct site country and operating metadata to match the physical installation. 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: A regional team deletes an old Mist site while several active APs and webhooks still reference its identifier. Here the selected action should produce: The AP selects permitted channels and the site record matches documented installation coordinates.

B:

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: The AP selects permitted channels and the site record matches documented installation coordinates.

D:

This check instead concerns a separate case: 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: The AP selects permitted channels and the site record matches documented installation coordinates.
