Question 40

A classroom receives a corporate WLAN configuration object but its AP profile never advertises the selected SSID. Which action should the specialist recommend FIRST?

  1. Use a common WLAN intent with supported site-specific network mapping parameters
  2. Coordinate WLAN-to-network mapping with the wired AP uplink and relevant trunk configuration
  3. Validate and replace inherited security policy references for the isolated test environment
  4. Bind the WLAN to the intended AP/site deployment target and verify actual beaconing

Explanation

Correct Answer

D:

WLAN objects must be scoped to the intended radios, sites, networks and associated security and portal dependencies. In the described case, bind the WLAN to the intended AP/site deployment target and verify actual beaconing resolves the identified control gap. Confirm with: A client scan detects the SSID on the correct APs and sees the approved security mode.

Incorrect Answers

A:

This is relevant to a separate wlan configuration objects and deployment problem: A campus needs the same staff SSID at two sites with distinct local IP subnets and different uplink mappings. It does not directly address this incident, which instead calls for: Bind the WLAN to the intended AP/site deployment target and verify actual beaconing.

Question 41

An international company copies a 6 GHz channel plan from one country into a region with different permitted indoor power rules. What corrective step most directly addresses the wireless fault?

  1. Account for DFS channel-availability checks and radar evacuation in the WLAN design
  2. Inventory actual 802.11 client band capabilities separately from BLE device radio usage
  3. Validate local regulatory domain and supported 6 GHz operating class before assigning channels
  4. Compute available channels after regulatory, DFS and site-specific exclusions before setting cell width

Explanation

Correct Answer

C:

Channel planning depends on supported frequency bands, local regulatory rules, widths and actual interference. In the described case, validate local regulatory domain and supported 6 GHz operating class before assigning channels resolves the identified control gap. Confirm with: The effective AP channel and power plan remains within the deployment country's permitted ranges.

Incorrect Answers

A:

This is relevant to a separate frequency bands and channel plans problem: A new 5 GHz channel is selected in a radar-sensitive range and APs unexpectedly change frequency when radar is detected. It does not directly address this incident, which instead calls for: Validate local regulatory domain and supported 6 GHz operating class before assigning channels.

B:

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: Validate local regulatory domain and supported 6 GHz operating class before assigning channels.

D:

This is relevant to a separate frequency bands and channel plans problem: A planner counts all nominal 5 GHz channels as simultaneously usable despite local DFS exclusions and reserved backhaul requirements.

This is relevant to a separate initial wireless setup and onboarding problem: A newly installed access point is powered from an old PoE switch port and reboots whenever both radios activate. It does not directly address this incident, which instead calls for: Correct the management VLAN DHCP scope and routed gateway option without modifying client SSIDs.

Question 43

A site forces maximum AP transmit power across a dense floor, increasing sticky-client connections and neighboring cell overlap. Which response best follows from the observed evidence?

  1. Adjust the RRM power design based on measured cell boundaries and client uplink behavior
  2. Inspect actual channel width and occupied spectral blocks, not only primary channel numbers
  3. Analyze actual available spectrum, regulatory limits and neighboring BSS occupancy
  4. Correlate spectrum interference with capacity classifiers and modify channel or physical placement

Explanation

Correct Answer

A:

RRM choices balance interference, legal channel/power limits, cell reuse, client needs and actual service-impact evidence. In the described case, adjust the RRM power design based on measured cell boundaries and client uplink behavior resolves the identified control gap. Confirm with: The revised client association distribution and retries improve without losing required coverage.

Incorrect Answers

B:

This is relevant to a separate radio resource management (rrm) problem: A campus deploys two APs on adjacent channels but their wide 80 MHz operating blocks still overlap heavily. It does not directly address this incident, which instead calls for: Adjust the RRM power design based on measured cell boundaries and client uplink behavior.

C:

This is relevant to a separate radio resource management (rrm) problem: An engineer assumes dynamic channel selection always avoids co-channel interference even when only one permissible channel is available.

Wireless service can fail because of wired uplink VLAN, Ethernet integrity or negotiated PoE limits even when RF is sound. In the described case, correct wired uplink VLAN/trunk policy to carry the intended locally bridged WLAN traffic resolves the identified control gap. Confirm with: A test guest receives an address from the approved segment while AP cloud management stays online.

Incorrect Answers

A:

This is relevant to a separate wired ap connectivity and poe problem: A building installs more APs on one switch than its aggregate PoE power budget can supply simultaneously. It does not directly address this incident, which instead calls for: Correct wired uplink VLAN/trunk policy to carry the intended locally bridged WLAN traffic.

C:

This is relevant to a separate wired ap connectivity and poe problem: An engineer assumes LLDP neighbors prove a mounted AP supports every requested switch port and PoE mode. It does not directly address this incident, which instead calls for: Correct wired uplink VLAN/trunk policy to carry the intended locally bridged WLAN traffic.

D:

This is relevant to a separate wired ap connectivity and poe problem: A wireless client loses calls because the AP's Ethernet uplink negotiates half-duplex and reports late collisions. It does not directly address this incident, which instead calls for: Correct wired uplink VLAN/trunk policy to carry the intended locally bridged WLAN traffic.

Question 48

A school uses Wi-Fi device presence to produce an occupancy estimate but its report includes unrelated devices seen from outside the building. What corrective step most directly addresses the wireless fault?

  1. Configure permitted location zones and verify Wi-Fi observation accuracy with representative scanners
  2. Revalidate the location model under the actual supported radio configuration
  3. Scope location observations to authorized site zones and assess signal reach and detection limitations
  4. Restrict location data export by organization scope, purpose and authorized access roles

Explanation

Correct Answer

C:

Wi-Fi location estimates require mapped APs, realistic uncertainty, appropriate time context and privacy-aware interpretation. In the described case, scope location observations to authorized site zones and assess signal reach and detection limitations resolves the identified control gap. Confirm with: An occupancy sample more closely matches the permitted indoor zone without counting neighboring networks.

Incorrect Answers

A:

This is relevant to a separate wi-fi location and mapping problem: A warehouse wants to use Wi-Fi location records to determine whether scanners visited a restricted loading area.
