Question 840

A retailer uses a Marvis interpretation generated before DNS failover to close a new incident created after failover. The incident lead approves this next step: Compare query timestamp and current network measurements before concluding the service has recovered. Which observation best confirms the correction worked?

  1. Marvis and client tests isolate name-resolution delay rather than an invented RF issue
  2. The root-cause record identifies the actual missing VLAN or DHCP path and confirms restored leasing
  3. Current resolution and application tests prove whether the new outage is still present
  4. The diagnostic result identifies the correct MAC or client record and time period

Explanation

Correct Answer

C:

Current resolution and application tests prove whether the new outage is still present directly tests the proposed corrective action: Compare query timestamp and current network measurements before concluding the service has recovered. Marvis reactive diagnosis requires the correct authorized client/site context and corroborating current operational measurements.

Incorrect Answers

A:

That observation would confirm another situation: A branch complains of DNS delay, but the support question says only that wireless signal is weak despite strong RSSI. Here the selected action should produce: Current resolution and application tests prove whether the new outage is still present.

B:

This check instead concerns a separate case: An engineer receives a Marvis finding about failed DHCP and immediately blames the AP without examining uplink VLAN configuration. Here the selected action should produce: Current resolution and application tests prove whether the new outage is still present.

D:

That evidence would establish success in a different scenario: A campus operator asks Marvis about a tablet but uses a device name shared by multiple devices in the inventory. Here the selected action should produce: Current resolution and application tests prove whether the new outage is still present.

Question 841

An MSP claims two organizations may share an identical API token because each portal has distinct site names. What should the engineer investigate or configure next?

  1. Issue appropriately scoped integration credentials for the correct organization and region
  2. Validate the supported AP telemetry path separately from client user-data forwarding
  3. Distinguish cloud control and telemetry from the actual locally bridged or tunneled WLAN forwarding design
  4. Document local IP services and permitted outbound management prerequisites for the selected devices

Explanation

Correct Answer

A:

Mist cloud control and observability are distinct from selected local or tunneled WLAN user-data forwarding paths. In the described case, issue appropriately scoped integration credentials for the correct organization and region resolves the identified control gap. Confirm with: An authorized script accesses only one intended tenant and requests against the other are rejected.

Incorrect Answers

B:

This is relevant to a separate cloud-managed wlan architecture and traffic paths problem: An engineer says service analytics are not available for a locally bridged WLAN because no user packets are sent to the public cloud. It does not directly address this incident, which instead calls for: Issue appropriately scoped integration credentials for the correct organization and region.

C:

This is relevant to a separate cloud-managed wlan architecture and traffic paths problem: A network architect assumes all client Wi-Fi traffic must traverse a public Mist cloud data center because the AP is cloud managed. It does not directly address this incident, which instead calls for: Issue appropriately scoped integration credentials for the correct organization and region.

D:

This is relevant to a separate cloud-managed wlan architecture and traffic paths problem: A branch deploys a new Mist-managed AP without identifying the role of DNS, DHCP and external cloud reachability in onboarding. It does not directly address this incident, which instead calls for: Issue appropriately scoped integration credentials for the correct organization and region.

Question 842

A multi-building WLAN uses one nominal SSID but guest portals differ by site due to inconsistent inherited configuration. Which response best follows from the observed evidence?

  1. Align effective WLAN security settings throughout the intended roaming service area
  2. Review the WLAN band selection and target AP radio capabilities before declaring a coverage defect
  3. Define distinct trust and access intents before choosing common or separate WLAN profiles
  4. Reconcile WLAN portal and authentication intent across all targeted site objects

Explanation

Correct Answer

D:

SSID availability, client admission, VLAN segmentation, QoS and actual service reachability are separate WLAN properties. In the described case, reconcile WLAN portal and authentication intent across all targeted site objects resolves the identified control gap. Confirm with: Guests see the approved portal flow at every intended building.

Incorrect Answers

A:

This is relevant to a separate wlan operational concepts problem: An engineer expects the SSID name alone to define a secure network despite inconsistent authentication on neighboring APs. It does not directly address this incident, which instead calls for: Reconcile WLAN portal and authentication intent across all targeted site objects.

B:

This is relevant to a separate wlan operational concepts problem: A university installs additional APs but forgets that one WLAN object is configured to operate only on a different frequency band. It does not directly address this incident, which instead calls for: Reconcile WLAN portal and authentication intent across all targeted site objects.

C:

This is relevant to a separate wlan operational concepts problem: A clinic provides one shared SSID for staff, guests and IoT equipment without separate identity or traffic policy requirements. It does not directly address this incident, which instead calls for: Reconcile WLAN portal and authentication intent across all targeted site objects.

Question 843

A busy lecture hall sees throughput failure but management assumes the slowest user's device is defective without checking contention. What is the most defensible next troubleshooting action?

  1. Scope the SLE to the affected AP and time rather than accepting the organization-wide average
  2. Follow the Internet Services or DNS-related connection classifier into the actual name-resolution dependency
  3. Use the Capacity and Throughput classifiers to distinguish client capability from excessive shared airtime
  4. Investigate non-Wi-Fi interference timing and mitigate the affected channel or physical placement

Explanation

Correct Answer

C:

SLE troubleshooting links the selected failed classifier to real client and upstream dependency evidence before changing infrastructure. In the described case, use the Capacity and Throughput classifiers to distinguish client capability from excessive shared airtime resolves the identified control gap. Confirm with: Time-aligned channel utilization identifies the root bottleneck and improves after an approved RF change.

Incorrect Answers

A:

This is relevant to a separate sle troubleshooting and root-cause classifiers problem: A WLAN reports a high Capacity success rate but a critical warehouse aisle has repeated non-Wi-Fi interference during one shift. It does not directly address this incident, which instead calls for: Use the Capacity and Throughput classifiers to distinguish client capability from excessive shared airtime.

B:

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: Use the Capacity and Throughput classifiers to distinguish client capability from excessive shared airtime.

D:

This is relevant to a separate sle troubleshooting and root-cause classifiers problem: A store experiences Capacity SLE degradation at lunchtime and the RF spectrum shows a neighboring microwave interfering on 2.4 GHz. It does not directly address this incident, which instead calls for: Use the Capacity and Throughput classifiers to distinguish client capability from excessive shared airtime.

Question 844

A deployment team considers a green dashboard proof that a WLAN is finished without testing real client roaming under load. Which configuration or control should the operator select?

  1. Validate wireless onboarding, guest authorization, DNS and Internet service before handover
  2. Require operational client acceptance tests during representative movement and peak utilization
  3. Stage WLAN changes with controlled scope, documented rollback and version comparison
  4. Plan a reversible phased cutover with explicit maintenance, compatibility and success gates

Explanation

Correct Answer

B:

The WLAN lifecycle includes requirements, RF survey, compatibility, staged deployment, client acceptance, operation and controlled retirement. In the described case, require operational client acceptance tests during representative movement and peak utilization resolves the identified control gap. Confirm with: A busy-hour test validates key clients' association, throughput and roaming against design objectives.

A:

This is relevant to a separate wlan lifecycle problem: A hotel turns up a guest WLAN but never performs an end-to-end client data path test after portal acceptance. It does not directly address this incident, which instead calls for: Require operational client acceptance tests during representative movement and peak utilization.

C:

This is relevant to a separate wlan lifecycle problem: A campus changes all access points simultaneously and loses the ability to isolate whether the fault came from firmware or policy. It does not directly address this incident, which instead calls for: Require operational client acceptance tests during representative movement and peak utilization.

D:

This is relevant to a separate wlan lifecycle problem: A WLAN team migrates to a new SSID without preserving a rollback option for payment handsets used around the clock. It does not directly address this incident, which instead calls for: Require operational client acceptance tests during representative movement and peak utilization.

Question 845

An engineer changes a WLAN's radio-band selection without checking whether the affected client fleet supports the replacement band. How should the team correct this specific WLAN problem?

  1. Constrain the WLAN template or site membership to the authorized pilot deployment
  2. Inventory client radio capabilities and stage a supported multi-band migration
  3. Inventory policy dependencies and migrate references before removing the retired WLAN
  4. Validate actual device configuration propagation and live client connectivity before closing the ticket

Explanation

Correct Answer

B:

WLAN objects must be scoped to the intended radios, sites, networks and associated security and portal dependencies. In the described case, inventory client radio capabilities and stage a supported multi-band migration resolves the identified control gap. Confirm with: Required clients discover the WLAN and service continues during the approved band transition.

Incorrect Answers

A:

This is relevant to a separate wlan configuration objects and deployment problem: A company enables a WLAN in every site through an inherited template when only its pilot lab should advertise it. It does not directly address this incident, which instead calls for: Inventory client radio capabilities and stage a supported multi-band migration.

C:

  2. Match Mist Edge responsibilities to the specific tunneled WLAN service rather than all AP traffic
  3. Validate data-center service reachability for tunneled WLAN clients including identity and address services
  4. Configure supported backup cluster associations and test AP tunnel failover behavior

Explanation

Correct Answer

D:

Mist Edge terminates selected tunneled WLAN data paths and needs independent tunnel, interface, routing, capacity and failover checks. In the described case, configure supported backup cluster associations and test AP tunnel failover behavior resolves the identified control gap. Confirm with: Access points re-establish their permitted data tunnels through the approved recovery cluster.

Incorrect Answers

A:

This is relevant to a separate juniper mist edge tunneling and resilience problem: A team deploys two edge appliances but both use the same physical power feed and uplink path during a resilience demonstration. It does not directly address this incident, which instead calls for: Configure supported backup cluster associations and test AP tunnel failover behavior.

B:

This is relevant to a separate juniper mist edge tunneling and resilience problem: An architect assumes Juniper Mist Edge processes every locally bridged wireless flow even when no WLAN tunnel is assigned. It does not directly address this incident, which instead calls for: Configure supported backup cluster associations and test AP tunnel failover behavior.

C:

This is relevant to a separate juniper mist edge tunneling and resilience problem: An engineer sends a corporate WLAN through the edge but leaves the route to the enterprise authentication server absent. It does not directly address this incident, which instead calls for: Configure supported backup cluster associations and test AP tunnel failover behavior.

Question 848

A large campus advertises the same WLAN twice with duplicate object names and different authentication profiles. Which network-management change is most appropriate?

  1. Provide a compatible WLAN service on supported bands for required legacy clients
  2. Reconcile target-organization WLAN dependencies rather than copying raw identifiers blindly
  3. Remove conflicting effective WLAN bindings and retain the single intended secured profile
  4. Enable the approved WLAN on supported radio bands and verify AP configuration delivery

Explanation

Correct Answer

C:

Mist WLAN configurations require correct effective inheritance and verified delivery to the intended access points.
