Question 160

A team wants near-real-time AP outages but its integration fetches a complete historical report once daily. Which network-management change is most appropriate?

  1. Carry appropriate device, site, event type and time context into downstream case creation
  2. Configure a supported event subscription and authorized webhook receiver for the relevant alerts
  3. Use durable processing and supported recovery or reconciliation for notification gaps
  4. Choose supported webhook event delivery for notifications and use a separate appropriate live stream or capture mechanism

Explanation

Correct Answer

B:

Event-driven webhook delivery needs authorized receivers, scoped event context, safe retries and reliable processing. In the described case, configure a supported event subscription and authorized webhook receiver for the relevant alerts resolves the identified control gap. Confirm with: A controlled AP disconnect produces a timely notification to the correct operational system.

Incorrect Answers

A:

This is relevant to a separate webhooks and event delivery problem: A site-alert webhook integration submits incident tickets without identifying which AP and SSID produced the event. It does not directly address this incident, which instead calls for: Configure a supported event subscription and authorized webhook receiver for the relevant alerts.

C:

This is relevant to a separate webhooks and event delivery problem: An alert receiving service silently drops webhooks during an Internet outage and never reconciles its missed monitoring window. It does not directly address this incident, which instead calls for: Configure a supported event subscription and authorized webhook receiver for the relevant alerts.

D:

This is relevant to a separate webhooks and event delivery problem: A developer assumes a webhook can stream raw packet-capture frames continuously over a two-way open session. It does not directly address this incident, which instead calls for: Configure a supported event subscription and authorized webhook receiver for the relevant alerts.

Question 161

A technician clones a template while dropping a referenced WxLAN rule, creating an unsecured access path. What should the engineer investigate or configure next?

  1. Preserve or explicitly reconcile dependent WLAN and policy objects during template migration
  2. Use supported site-specific VLAN mapping or a scoped configuration override
  3. Apply governed versioning and validate the actual target scope before deployment
  4. Inspect the supported configuration precedence and the resulting device configuration

Explanation

Correct Answer

A:

Reusable Mist configuration objects require correct references, inheritance, target membership and verified device delivery. In the described case, preserve or explicitly reconcile dependent WLAN and policy objects during template migration resolves the identified control gap. Confirm with: The deployed clone enforces the same approved security rules at the destination site.

Incorrect Answers

B:

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: Preserve or explicitly reconcile dependent WLAN and policy objects during template migration.

C:

This is relevant to a separate mist configuration objects and inheritance problem: A central administrator changes an RF template without documenting who approved the change or which access points inherited it. It does not directly address this incident, which instead calls for: Preserve or explicitly reconcile dependent WLAN and policy objects during template migration.

D:

This is relevant to a separate mist configuration objects and inheritance problem: A Mist site has both local WLAN settings and an organization template, and operators cannot explain which parameters take effect. It does not directly address this incident, which instead calls for: Preserve or explicitly reconcile dependent WLAN and policy objects during template migration.

Question 162

A warehouse's Roaming SLE drops only when barcode terminals move past shelving at one location. Which response best follows from the observed evidence?

  1. Follow the Internet Services or DNS-related connection classifier into the actual name-resolution dependency
  2. Validate telemetry coverage, client count and AP state before accepting the result
  3. Perform RF measurements of the altered obstruction and correct AP location or antenna orientation
  4. Correlate handoff events, cell overlap and client capability near the affected aisle

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, correlate handoff events, cell overlap and client capability near the affected aisle resolves the identified control gap. Confirm with: The moving scanner completes transitions without the previously observed repeated disconnects.

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: Correlate handoff events, cell overlap and client capability near the affected aisle.

B:

This is relevant to a separate sle troubleshooting and root-cause classifiers problem: An enterprise SLE reports improved success after all impaired clients disconnect, shrinking the observation population. It does not directly address this incident, which instead calls for: Correlate handoff events, cell overlap and client capability near the affected aisle.

C:

This is relevant to a separate sle troubleshooting and root-cause classifiers problem: A WLAN's Coverage SLE drops sharply after access points are moved behind new metal partitions. It does not directly address this incident, which instead calls for: Correlate handoff events, cell overlap and client capability near the affected aisle.

Question 163

An analyst receives a Marvis answer that names RF interference but dismisses conflicting packet evidence from the same client. What is the most defensible next troubleshooting action?

  1. Confirm client capability, RF quality and competing access point evidence before replacing hardware
  2. Compare query timestamp and current network measurements before concluding the service has recovered
  3. Respect tenant authorization and request a properly scoped operational context
  4. Validate the conversational diagnosis against its underlying client and AP event evidence

Explanation

Correct Answer

D:

Marvis reactive diagnosis requires the correct authorized client/site context and corroborating current operational measurements. In the described case, validate the conversational diagnosis against its underlying client and AP event evidence resolves the identified control gap. Confirm with: A technical trace confirms or revises the suspected cause before any radio adjustment.

Incorrect Answers

A:

This is relevant to a separate marvis reactive troubleshooting problem: A network team uses Marvis to claim a client has an antenna fault based only on one poor throughput sample. It does not directly address this incident, which instead calls for: Validate the conversational diagnosis against its underlying client and AP event evidence.

B:

This is relevant to a separate marvis reactive troubleshooting problem: A retailer uses a Marvis interpretation generated before DNS failover to close a new incident created after failover. It does not directly address this incident, which instead calls for: Validate the conversational diagnosis against its underlying client and AP event evidence.

C:

This is relevant to a separate marvis reactive troubleshooting problem: A branch operator asks a natural-language question about a network that belongs to a different customer account. It does not directly address this incident, which instead calls for: Validate the conversational diagnosis against its underlying client and AP event evidence.

Question 164

A school shares one Mist subscription record across two separately owned customer organizations without authority. Which configuration or control should the operator select?

  1. Allocate cloud service entitlements to the authorized organization and device inventory
  2. Scope the management role to intended sites and test inherited organization permissions
  3. Use distinct organizations where customer tenant ownership requires isolation rather than merely adding sites
  4. Assign a role with the minimum required site and monitoring privileges

Explanation

Correct Answer

A:

Mist organization scope, least-privilege identities and active subscriptions must match the responsible tenant and deployed services. In the described case, allocate cloud service entitlements to the authorized organization and device inventory resolves the identified control gap. Confirm with: Each customer sees only its legitimate subscription and the active services authorized for its assets.

Incorrect Answers

B:

This is relevant to a separate account organization and subscriptions problem: A global WLAN uses site-specific administrators yet a template editor is inadvertently allowed to change every international location. It does not directly address this incident, which instead calls for: Allocate cloud service entitlements to the authorized organization and device inventory.

It does not directly address this incident, which instead calls for: Allocate cloud service entitlements to the authorized organization and device inventory.

Question 165

A site receives repeated AP health anomalies but the team keeps resetting every AP without examining the common PoE switch. How should the team correct this specific WLAN problem?

  1. Confirm the proactive finding with current SLE and client impact evidence before a disruptive response
  2. Use Marvis firmware compliance findings with actual model and site context
  3. Treat proactive findings as evidence-based risk signals requiring validation rather than deterministic forecasts
  4. Correlate proactively detected wireless issues with shared upstream infrastructure

Explanation

Correct Answer

D:

Proactive Marvis findings help detect network risk before users complain but do not remove the need for controlled verification. In the described case, correlate proactively detected wireless issues with shared upstream infrastructure resolves the identified control gap. Confirm with: A switch-level repair eliminates recurring AP alarms and related client interruptions.

Incorrect Answers

A:

This is relevant to a separate marvis proactive troubleshooting problem: An AI-derived performance warning leads a campus NOC to disable an entire student WLAN before verifying whether the reported problem is ongoing. It does not directly address this incident, which instead calls for: Correlate proactively detected wireless issues with shared upstream infrastructure.

B:

This is relevant to a separate marvis proactive troubleshooting problem: A college wants to identify APs running an inconsistent firmware release but does not monitor approved model-specific versions.

  1. Use scoped authentication and enforce separate privileges for read and write API methods
  2. Read back both configured resource state and device deployment status after the API change
  3. Validate organization ownership and explicit resource identity before any high-impact API deletion
  4. Select the official region-specific API host and corresponding organization context

Explanation

Correct Answer

A:

Mist API operations require the supported method, region, stable resource identity, scoped credentials and post-write readback. In the described case, use scoped authentication and enforce separate privileges for read and write API methods resolves the identified control gap. Confirm with: Read-only requests succeed while unauthorized destructive calls receive explicit denial.

Incorrect Answers

B:

This is relevant to a separate restful api concepts problem: An integration assumes a successful HTTP request response means an AP has already applied the new configuration. It does not directly address this incident, which instead calls for: Use scoped authentication and enforce separate privileges for read and write API methods.

C:

This is relevant to a separate restful api concepts problem: A scheduled script deletes a site using an unverified variable that sometimes refers to another organization. It does not directly address this incident, which instead calls for: Use scoped authentication and enforce separate privileges for read and write API methods.

D:

This is relevant to a separate restful api concepts problem: An engineer writes requests to a Mist API endpoint in the wrong regional cloud and receives tenant-not-found errors. It does not directly address this incident, which instead calls for: Use scoped authentication and enforce separate privileges for read and write API methods.

Question 168

A hospital enables mandatory 802.11r fast transition on a legacy device population that cannot complete FT handshakes. Which network-management change is most appropriate?

  1. Align effective WLAN security parameters throughout the intended roaming domain
  2. Inspect client roaming decisions, neighbor information and RF thresholds before raising every AP's power
  3. Validate client FT interoperability and choose a compatible supported roaming configuration
  4. Evaluate dual-band client capabilities and steering policy against real association outcomes

Explanation

Correct Answer

C:

Association, EAP authorization, DHCP and roaming transitions are distinct stages with distinct evidence and failure modes. In the described case, validate client FT interoperability and choose a compatible supported roaming configuration resolves the identified control gap. Confirm with: Old clients complete roaming while newer fast-transition clients retain the intended behavior.

Incorrect Answers

A:

This is relevant to a separate wlan association and roaming problem: A campus uses the same SSID on different security modes at neighboring APs, preventing seamless reassociation for managed laptops. It does not directly address this incident, which instead calls for: Validate client FT interoperability and choose a compatible supported roaming configuration.

B:

This is relevant to a separate wlan association and roaming problem: A warehouse scanner remains associated with an AP two aisles away while passing closer APs and repeatedly loses packets. It does not directly address this incident, which instead calls for: Validate client FT interoperability and choose a compatible supported roaming configuration.

D:

This is relevant to a separate wlan association and roaming problem: A university sees association retries after enabling band steering but no one checks whether older clients support the preferred band. It does not directly address this incident, which instead calls for: Validate client FT interoperability and choose a compatible supported roaming configuration.

Question 169

A hospital AP shows acceptable RSSI but application performance falls when nearby industrial machinery raises the noise floor. What should the engineer investigate or configure next?

  1. Account for antenna directivity, installed orientation and allowed EIRP in the site survey
  2. Apply appropriate path-loss expectations and field measurements when evaluating increased distance
  3. Investigate signal-to-noise ratio and non-Wi-Fi noise rather than absolute RSSI alone
  4. Evaluate SNR margin under actual traffic and interferer conditions before declaring RF health

Explanation

Correct Answer

C:

RF planning must account for bidirectional signal, noise, building attenuation and actual antenna propagation. In the described case, investigate signal-to-noise ratio and non-Wi-Fi noise rather than absolute RSSI alone resolves the identified control gap. Confirm with: The recorded SNR drops during machine use and rises when interference is removed.

Incorrect Answers

A:

This is relevant to a separate rf fundamentals and propagation problem: A retail RF design uses an isotropic antenna calculation for a directional panel antenna without considering its beam pattern. It does not directly address this incident, which instead calls for: Investigate signal-to-noise ratio and non-Wi-Fi noise rather than absolute RSSI alone.

B:

This is relevant to a separate rf fundamentals and propagation problem: A warehouse planner doubles distance from an access point and expects the received signal to remain unchanged in open space. It does not directly address this incident, which instead calls for: Investigate signal-to-noise ratio and non-Wi-Fi noise rather than absolute RSSI alone.

D:

This is relevant to a separate rf fundamentals and propagation problem: A radio report identifies a large received noise value but operations assumes a clean channel because device RSSI is high. It does not directly address this incident, which instead calls for: Investigate signal-to-noise ratio and non-Wi-Fi noise rather than absolute RSSI alone.

Question 170

A campus sees low Time to Connect while all authentication exchanges complete quickly but DHCP replies arrive late. Which response best follows from the observed evidence?

  1. Check the selected SLE definition and measured denominator rather than using the number as uptime
  2. Audit measurement coverage and disconnected AP inventory before interpreting the improvement
  3. Compare actual handoff interval and supported fast-transition behavior to the Roaming threshold
  4. Drill into the DHCP classifier under the relevant client onboarding metric

Explanation

Correct Answer

D:

Wireless SLEs measure defined client-experience success and classifiers; different metrics and denominators are not interchangeable. In the described case, drill into the DHCP classifier under the relevant client onboarding metric resolves the identified control gap. Confirm with: A time-scoped client event trace isolates DHCP delay as the dominant connection-time component.

Incorrect Answers

A:

This is relevant to a separate wireless assurance sle metric interpretation problem: 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. It does not directly address this incident, which instead calls for: Drill into the DHCP classifier under the relevant client onboarding metric.

B:

This is relevant to a separate wireless assurance sle metric interpretation problem: A site reports 100 percent successful wireless connects after every failing AP stopped reporting telemetry. It does not directly address this incident, which instead calls for: Drill into the DHCP classifier under the relevant client onboarding metric.

C:

This is relevant to a separate wireless assurance sle metric interpretation problem: A voice handset remains associated but its Roaming SLE fails when it takes a long time to move between neighboring APs.
