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. It does not directly address this incident, which instead calls for: Drill into the DHCP classifier under the relevant client onboarding metric.

Question 171

A help desk interprets a Wi-Fi interferer alert as proof that the device is a malicious rogue AP. What is the most defensible next troubleshooting action?

  1. Investigate unauthorized SSID and authentication server identity together using WIDS evidence
  2. Investigate wired attachment, inventory and physical location to determine the rogue-device category
  3. Scope the exception to the documented BSSID or device identity and retain broad detection coverage
  4. Differentiate RF interference from an unauthorized infrastructure device before assigning security severity

Explanation

Correct Answer

D:

Wireless intrusion monitoring requires evidence-based classification of rogue, interfering and authorized devices and bounded response. In the described case, differentiate RF interference from an unauthorized infrastructure device before assigning security severity resolves the identified control gap. Confirm with: An inspection identifies the emitter and categorizes its security relevance using appropriate evidence.

Incorrect Answers

A:

This is relevant to a separate wireless intrusion detection and prevention problem: A branch identifies an evil-twin SSID but analysts never compare the fake authentication portal with the approved server certificate. It does not directly address this incident, which instead calls for: Differentiate RF interference from an unauthorized infrastructure device before assigning security severity.

B:

This is relevant to a separate wireless intrusion detection and prevention problem: A security report calls every unrecognized BSSID rogue without distinguishing unauthorized devices connected to enterprise wired infrastructure. It does not directly address this incident, which instead calls for: Differentiate RF interference from an unauthorized infrastructure device before assigning security severity.

C:

This is relevant to a separate wireless intrusion detection and prevention problem: A customer creates a rogue suppression exception for one approved test AP and it accidentally disables detection for all SSIDs at the site. It does not directly address this incident, which instead calls for: Differentiate RF interference from an unauthorized infrastructure device before assigning security severity.

Question 172

An engineer claims that WLAN stations can transmit and receive at full speed simultaneously on one half-duplex radio channel. Which configuration or control should the operator select?

  1. Inspect RF channel occupancy from all transmitters rather than only the local SSID traffic
  2. Review both physical channel sensing and virtual carrier reservation in the contention analysis
  3. Reduce unnecessary broadcast airtime and legacy low-rate behavior within supported service requirements
  4. Explain the shared medium and verify actual channel occupancy during bidirectional load

Explanation

Correct Answer

D:

Wi-Fi uses a shared contention-based medium; access-category priority and radio efficiency cannot be inferred from RSSI alone. In the described case, explain the shared medium and verify actual channel occupancy during bidirectional load resolves the identified control gap. Confirm with: The capture shows arbitration and alternating transmissions rather than simultaneous full-duplex use.

Incorrect Answers

A:

This is relevant to a separate network arbitration and contention problem: A wireless link is slow while the AP reports low Internet usage because a neighboring BSS occupies the same channel. It does not directly address this incident, which instead calls for: Explain the shared medium and verify actual channel occupancy during bidirectional load.

B:

This is relevant to a separate network arbitration and contention problem: A technician assumes a successful physical carrier sense means virtual NAV reservations can be ignored. It does not directly address this incident, which instead calls for: Explain the shared medium and verify actual channel occupancy during bidirectional load.

C:

This is relevant to a separate network arbitration and contention problem: A high-density venue uses 2.4 GHz with many low-rate broadcasts and sees large delays for unicast voice frames. It does not directly address this incident, which instead calls for: Explain the shared medium and verify actual channel occupancy during bidirectional load.

Question 173

A consultant moves an AP between two customers by changing its site name while leaving organization ownership unchanged. How should the team correct this specific WLAN problem?

  1. Inventory site dependencies and migrate or retire affected devices and integrations before deletion
  2. Correct the site record and floorplan association before accepting the location deployment
  3. Validate stable site identifiers and move the AP into the actual managed location
  4. Use the supported device ownership transfer or claim reconciliation rather than relabeling a site

Explanation

Correct Answer

D:

Mist organizations provide ownership boundaries while sites represent actual locations with correct device membership and metadata. In the described case, use the supported device ownership transfer or claim reconciliation rather than relabeling a site resolves the identified control gap. Confirm with: Hardware inventory shows only its legitimate receiving organization as owner.

Incorrect Answers

A:

This is relevant to a separate organization and site objects problem: A regional team deletes an old Mist site while several active APs and webhooks still reference its identifier. It does not directly address this incident, which instead calls for: Use the supported device ownership transfer or claim reconciliation rather than relabeling a site.

B:

This is relevant to a separate organization and site objects problem: An international company uses the same geographic address for two Mist sites and asset location results appear on the wrong floorplan. It does not directly address this incident, which instead calls for: Use the supported device ownership transfer or claim reconciliation rather than relabeling a site.

C:

This is relevant to a separate organization and site objects problem: A device is accidentally assigned to a similarly named site in another time zone and displays unrelated troubleshooting data. It does not directly address this incident, which instead calls for: Use the supported device ownership transfer or claim reconciliation rather than relabeling a site.

Question 174

  2. Size Mist Edge capacity and cluster distribution against expected tunneled WLAN demand
  3. Separate supported management and tunnel-data interface addressing according to the platform requirements
  4. Match Mist Edge responsibilities to the specific tunneled WLAN service rather than all AP traffic

Explanation

Correct Answer

C:

Mist Edge terminates selected tunneled WLAN data paths and needs independent tunnel, interface, routing, capacity and failover checks. In the described case, separate supported management and tunnel-data interface addressing according to the platform requirements resolves the identified control gap. Confirm with: Interface state and routing checks show distinct approved IP subnets for OOBM and data tunneling.

Incorrect Answers

A:

This is relevant to a separate juniper mist edge tunneling and resilience problem: A disaster recovery plan includes an alternate Mist Edge cluster but AP profiles reference only the failed primary endpoint. It does not directly address this incident, which instead calls for: Separate supported management and tunnel-data interface addressing according to the platform requirements.

B:
