Question 400

A store experiences Capacity SLE degradation at lunchtime and the RF spectrum shows a neighboring microwave interfering on 2.4 GHz. What is the most defensible next troubleshooting action?

  1. Follow the Internet Services or DNS-related connection classifier into the actual name-resolution dependency
  2. Filter SLE, client and classifier evidence to the exact incident window
  3. Use AP Health Ethernet or network classifiers and switch interface counters for diagnosis
  4. Investigate non-Wi-Fi interference timing and mitigate the affected channel or physical placement

Explanation

Correct Answer

D:

SLE troubleshooting links the selected failed classifier to real client and upstream dependency evidence before changing infrastructure. In the described case, investigate non-Wi-Fi interference timing and mitigate the affected channel or physical placement resolves the identified control gap. Confirm with: Channel-busy measurements improve and handheld transactions succeed during the problem period.

Incorrect Answers

A:

This is relevant to a separate sle troubleshooting and root-cause classifiers problem: A school has repeated Time to Connect problems because its client DNS service is unreachable after successful authorization and DHCP. It does not directly address this incident, which instead calls for: Investigate non-Wi-Fi interference timing and mitigate the affected channel or physical placement.

B:

This is relevant to a separate sle troubleshooting and root-cause classifiers problem: A campus WLAN quality score is poor but the operator studies the previous month rather than the reported afternoon outage. It does not directly address this incident, which instead calls for: Investigate non-Wi-Fi interference timing and mitigate the affected channel or physical placement.

C:

This is relevant to a separate sle troubleshooting and root-cause classifiers problem: An AP's Ethernet interface drops packets under load while wireless error counters appear normal. It does not directly address this incident, which instead calls for: Investigate non-Wi-Fi interference timing and mitigate the affected channel or physical placement.

Question 401

An enterprise uses PEAP with weak passwords and treats the outer TLS tunnel as proof that credential phishing is impossible. Which configuration or control should the operator select?

  1. Specify and test separate approved authentication flows for the relevant SSIDs and client groups
  2. Validate actual negotiated authentication and cryptographic mode for each client class
  3. Strengthen supplicant server validation and migrate to appropriate phishing-resistant authentication where supported
  4. Validate the returned policy, VLAN or role independently of authentication success

Explanation

Correct Answer

C:

Wireless security requires supported link encryption, trusted identity/certificates and least-privilege authorization beyond naming an SSID. In the described case, strengthen supplicant server validation and migrate to appropriate phishing-resistant authentication where supported resolves the identified control gap. Confirm with: A rogue authentication endpoint is rejected and authorized logins follow approved policy.

Incorrect Answers

A:

This is relevant to a separate wireless security and authentication problem: A WLAN offers both a captive portal and enterprise certificate authentication, but the design does not state which users follow each method. It does not directly address this incident, which instead calls for: Strengthen supplicant server validation and migrate to appropriate phishing-resistant authentication where supported.

B:

This is relevant to a separate wireless security and authentication problem: A high-security office enables WPA2/WPA3 transition mode without checking whether its intended devices downgrade to weaker protection. It does not directly address this incident, which instead calls for: Strengthen supplicant server validation and migrate to appropriate phishing-resistant authentication where supported.

D:

This is relevant to a separate wireless security and authentication problem: An auditor treats a successful EAP authentication event as proof that the user's assigned WLAN role is appropriately restricted. It does not directly address this incident, which instead calls for: Strengthen supplicant server validation and migrate to appropriate phishing-resistant authentication where supported.

Question 402

A network team copies a multi-PSK inventory between sites without auditing which credentials correspond to staff versus IoT groups. How should the team correct this specific WLAN problem?

  1. Reconcile key ownership and mapped network privileges before enabling the imported policy
  2. Issue distinct scoped keys and test cross-unit denial through WLAN policy
  3. Configure supported multiple PSK policy mapping to the intended student groups or network segments
  4. Use a supported per-device or per-group multiple-PSK design with documented key lifecycle

Explanation

Correct Answer

A:

Multiple-PSK designs can distinguish devices or groups only when credentials, scope, entitlements and network roles are governed. In the described case, reconcile key ownership and mapped network privileges before enabling the imported policy resolves the identified control gap. Confirm with: Each test PSK is attributable to an authorized group and delivers its expected role or VLAN.

Incorrect Answers

B:

This is relevant to a separate multiple and cloud psks problem: A network review finds PSK values are reused among independent business units although separation is required by policy. It does not directly address this incident, which instead calls for: Reconcile key ownership and mapped network privileges before enabling the imported policy.

C:

This is relevant to a separate multiple and cloud psks problem: A school needs separate classroom VLAN roles on one SSID but all students share a single personal passphrase. It does not directly address this incident, which instead calls for: Reconcile key ownership and mapped network privileges before enabling the imported policy.

D:

This is relevant to a separate multiple and cloud psks problem: A warehouse deploys dozens of IoT readers that lack 802.1X support but the company requires per-device revocation. It does not directly address this incident, which instead calls for: Reconcile key ownership and mapped network privileges before enabling the imported policy.

Question 403

An engineer compares proximity dwell reports from two sites that use incompatible zone sizes and different encounter intervals. Which action should the specialist recommend FIRST?

  1. Create approved proximity zones and appropriate entry and exit thresholds for the intended areas
  2. Implement the supported paired proximity entry and exit event processing
  3. Normalize zone definitions and measurement settings before drawing utilization comparisons
  4. Limit proximity analytics by permitted purpose, privacy policy, access and retention

Explanation

Correct Answer

C:

Proximity tracing depends on permitted zone definitions, client sources, RSSI thresholds, encounter duration and privacy controls. In the described case, normalize zone definitions and measurement settings before drawing utilization comparisons resolves the identified control gap. Confirm with: The evaluation names equivalent spatial and time criteria with comparable occupancy observations.

Incorrect Answers

A:

This is relevant to a separate proximity tracing and occupancy analytics problem: A museum wants to analyze which exhibit zones visitors approached but defines no proximity zones or RSSI thresholds on its location map. It does not directly address this incident, which instead calls for: Normalize zone definitions and measurement settings before drawing utilization comparisons.

B:

This is relevant to a separate proximity tracing and occupancy analytics problem: A facility configures zone entry on an RSSI threshold but omits exit event handling, so occupancy never decreases. It does not directly address this incident, which instead calls for: Normalize zone definitions and measurement settings before drawing utilization comparisons.

D:

This is relevant to a separate proximity tracing and occupancy analytics problem: A campus uses proximity reports to identify individual staff movement without defining legal purpose or authorized access.

  1. Refresh the relevant context and verify postchange telemetry before taking another action
  2. Review action scope, policy authority and operational impact before applying the recommended change
  3. Check telemetry source freshness and management connectivity before trusting negative findings
  4. Resolve the specific authorized client identity before relying on the query response

Explanation

Correct Answer

A:

Marvis reactive diagnosis requires the correct authorized client/site context and corroborating current operational measurements. In the described case, refresh the relevant context and verify postchange telemetry before taking another action resolves the identified control gap. Confirm with: New client transactions agree with the updated policy state and the current diagnosis.

Incorrect Answers

B:

This is relevant to a separate marvis reactive troubleshooting problem: A technician treats a Marvis natural-language result as permission to change authentication roles without a separate change approval. It does not directly address this incident, which instead calls for: Refresh the relevant context and verify postchange telemetry before taking another action.

C:

This is relevant to a separate marvis reactive troubleshooting problem: A new analyst interprets the absence of Marvis findings for a branch as proof that no service outage exists, although all APs stopped reporting. It does not directly address this incident, which instead calls for: Refresh the relevant context and verify postchange telemetry before taking another action.

D:

This is relevant to a separate marvis reactive troubleshooting problem: A campus operator asks Marvis about a tablet but uses a device name shared by multiple devices in the inventory. It does not directly address this incident, which instead calls for: Refresh the relevant context and verify postchange telemetry before taking another action.

Question 405

A client sees two SSIDs with the same name but one operates on an unsupported 6 GHz band only. Which network-management change is most appropriate?

  1. Replan 2.4 GHz cells around practical non-overlapping channels with site-specific RF measurements
  2. Preserve a compatible supported band for the legacy clients while planning 6 GHz adoption
  3. Separate diagnostics by radio band and channel before attributing source and impact
  4. Inventory actual 802.11 client band capabilities separately from BLE device radio usage

Explanation

Correct Answer

B:

Channel planning depends on supported frequency bands, local regulatory rules, widths and actual interference. In the described case, preserve a compatible supported band for the legacy clients while planning 6 GHz adoption resolves the identified control gap. Confirm with: The legacy device discovers its permitted SSID and an EHT-capable test device uses the 6 GHz service.

Incorrect Answers

A:

This is relevant to a separate frequency bands and channel plans problem: A cafe packs four nearby APs on overlapping 2.4 GHz channels and clients spend much of the hour waiting to transmit. It does not directly address this incident, which instead calls for: Preserve a compatible supported band for the legacy clients while planning 6 GHz adoption.

C:

This is relevant to a separate frequency bands and channel plans problem: A remote branch misidentifies interference because its spectrum report aggregates both 2.4 GHz and 5 GHz into one average. It does not directly address this incident, which instead calls for: Preserve a compatible supported band for the legacy clients while planning 6 GHz adoption.

D:

This is relevant to a separate frequency bands and channel plans problem: A retail site disables 2.4 GHz for all clients although installed BLE sensors are unrelated and many payment handhelds still use 2.4 GHz Wi-Fi. It does not directly address this incident, which instead calls for: Preserve a compatible supported band for the legacy clients while planning 6 GHz adoption.

Question 406

A wireless client loses calls because the AP's Ethernet uplink negotiates half-duplex and reports late collisions. What should the engineer investigate or configure next?

  1. Check the specified device power class and enable sufficient supported PoE supply
  2. Confirm negotiated LLDP power and actual Ethernet link parameters on the supported hardware
  3. Fix the physical port negotiation or cabling issue instead of tuning only wireless radio power
  4. Measure Ethernet physical errors and cable health before changing 802.11 channel settings

Explanation

Correct Answer

C:

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: Validate actual hardware compatibility and service entitlement before promising virtual beacon features.

Question 408

A campus assumes OFDMA prevents every overlapping Wi-Fi cell from competing for the same channel. What is the most defensible next troubleshooting action?

  1. Diagnose CSMA/CA contention and airtime demand before increasing AP transmit power
  2. Explain the shared medium and verify actual channel occupancy during bidirectional load
  3. Distinguish within-BSS scheduled transmissions from inter-BSS shared-medium coordination
  4. Separate 802.11 MAC acknowledgment and retry behavior from upper-layer transport retransmissions

Explanation

Correct Answer

C:

Wi-Fi uses a shared contention-based medium; access-category priority and radio efficiency cannot be inferred from RSSI alone. In the described case, distinguish within-BSS scheduled transmissions from inter-BSS shared-medium coordination resolves the identified control gap. Confirm with: Two overlapping cells still show channel-busy contention even with OFDMA-capable clients.

Incorrect Answers

A:

This is relevant to a separate network arbitration and contention problem: A crowded classroom shows strong signal on all devices but hundreds of collisions and backoffs during simultaneous uploads. It does not directly address this incident, which instead calls for: Distinguish within-BSS scheduled transmissions from inter-BSS shared-medium coordination.

B:

This is relevant to a separate network arbitration and contention problem: An engineer claims that WLAN stations can transmit and receive at full speed simultaneously on one half-duplex radio channel. It does not directly address this incident, which instead calls for: Distinguish within-BSS scheduled transmissions from inter-BSS shared-medium coordination.

D:

This is relevant to a separate network arbitration and contention problem: A branch IT team treats a Wi-Fi retransmission as evidence that TCP alone has already recovered the lost wireless frame. It does not directly address this incident, which instead calls for: Distinguish within-BSS scheduled transmissions from inter-BSS shared-medium coordination.

Question 409

A WLAN Action indicates a tunnel anomaly at Mist Edge but the NOC changes only the 2.4 GHz channel plan. Which configuration or control should the operator select?

  1. Check the action category, subscription and selected automation permissions before changing firmware
  2. Compare actual impacted user periods and verify sustained recovery before dismissing the Action
  3. Inspect indicated edge-tunnel traffic and interface evidence before RF intervention
  4. Inspect the organization-level Action grouping and common authentication server evidence

Explanation

Correct Answer

C:

Marvis Actions can guide operators or execute permitted self-driving changes; scope, authorization and outcome remain essential. In the described case, inspect indicated edge-tunnel traffic and interface evidence before RF intervention resolves the identified control gap. Confirm with: The recovered data tunnel and guest client path resolve the issue independently of radio settings.

Incorrect Answers

A:

This is relevant to a separate marvis actions, driver-assist and self-driving problem: A help desk sees a Marvis Action about firmware noncompliance but does not know whether it is driver-assist or permitted self-driving. It does not directly address this incident, which instead calls for: Inspect indicated edge-tunnel traffic and interface evidence before RF intervention.

B:

This is relevant to a separate marvis actions, driver-assist and self-driving problem: A hospital suppresses a high-priority Marvis Action because the site score briefly improved during an empty-night interval. It does not directly address this incident, which instead calls for: Inspect indicated edge-tunnel traffic and interface evidence before RF intervention.

D:

This is relevant to a separate marvis actions, driver-assist and self-driving problem: A retail organization has one Marvis Action combining Wi-Fi authentication failures across multiple branches but support assigns separate unrelated root causes. It does not directly address this incident, which instead calls for: Inspect indicated edge-tunnel traffic and interface evidence before RF intervention.

Question 410

A network team changes device ownership during an acquisition without checking whether licensed WLAN features remain available under the receiving organization. How should the team correct this specific WLAN problem?

  1. Plan entitlement and device-claim reconciliation as part of the organization migration
