Question 1070

An office installs a new 6 GHz-capable AP, but an older 802.11ac laptop cannot detect the dedicated 6 GHz-only SSID. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Replan the 2.4 GHz channel assignments using nonoverlapping channels and measured interference.
  2. Provide an appropriate supported 5 GHz service for legacy clients instead of assuming 6 GHz backward compatibility.
  3. Maintain a device band-capability inventory when expanding Wi-Fi 6E coverage.
  4. Require predictive and post-deployment validation for material building changes.

Explanation

Correct Answers

B:

This is the corrective intervention because a 5 GHz-only 802.11ac radio cannot discover or join a 6 GHz WLAN. Confirm its effect using the specified operational recovery check.

C:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: a hospital's staff WLAN has strong signal near APs but frequent retries in a wing where two adjacent APs use the same busy 2.4 GHz channel. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a wireless floor gets poor coverage behind dense concrete despite high AP transmit power in the corridor. It does not specifically prevent this problem.

Question 1071

A stadium's WLAN uses 80 MHz channels everywhere, producing excessive overlapping BSSs during a sold-out event. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Reorient or replace the antenna according to the validated coverage design.
  2. Use narrower 5 GHz channel widths where validated by high-density RF design and channel availability.
  3. Survey occupied locations instead of relying on corridor sample points.
  4. Validate channel width against density and spectrum occupancy at each event venue.

Explanation

Correct Answers

B:

This is the corrective intervention because very wide channels reduce the number of reusable channel blocks in dense environments. Confirm its effect using the specified operational recovery check.

D:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: an AP is installed with a directional antenna pointed into a concrete wall rather than the intended warehouse aisle. It is not the targeted repair for this case.

C:

That safeguard would suit a different situation, such as when a video conference room's clients show low RSSI but good signal-to-noise ratio only near the door; the meeting area itself is below the survey target. It does not specifically prevent this problem.

Question 1072

A conference room has healthy RSSI but intermittent audio latency when several nearby clients transmit on the same channel. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Provide approved compatible security service or a planned device upgrade, without falsely claiming WPA3 support on legacy devices.
  2. Diagnose airtime contention and RF interference rather than increasing transmit power without evidence.
  3. Validate channel width against density and spectrum occupancy at each event venue.
  4. Include retry and airtime measurements in WLAN quality baselines.

Explanation

Correct Answers

B:

This is the corrective intervention because strong RSSI does not rule out busy-channel contention and wireless retransmissions. Confirm its effect using the specified operational recovery check.

D:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: a campus is migrating staff to WPA3-Enterprise but several devices only support WPA2-Enterprise. It is not the targeted repair for this case.

C:

That safeguard would suit a different situation, such as when a stadium's WLAN uses 80 MHz channels everywhere, producing excessive overlapping BSSs during a sold-out event. It does not specifically prevent this problem.

Question 1073

An AP shows DFS radar events and channels change during business hours, interrupting some clients. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Balance AP cell size and client transmit capability and adjust RF design for bidirectional reachability.
  2. Replan channels and DFS use according to regulatory requirements and service tolerance, never disable mandatory radar protection.
  3. Test 802.11r interoperability rather than enabling it blindly on every SSID.
  4. Monitor radar events and use regulatory-safe channel planning.

Explanation

Correct Answers

B:

This is the corrective intervention because regulated DFS channels require evacuation when radar is detected. Confirm its effect using the specified operational recovery check.

D:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: a VoIP design attempts to solve poor call quality solely by raising AP power while clients still transmit at weak power levels. It is not the targeted repair for this case.

C:

That safeguard would suit a different situation, such as when a voice WLAN introduces rapid roaming requirements, but the configuration has no support for the client-compatible 802.11r fast transition mechanism. It does not specifically prevent this problem.

Question 1074

A warehouse handheld disconnects while roaming between APs because its target radios have different SSID security settings. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Move the legacy device to an approved separate compatible service or replace it while keeping mandatory PMF on the protected WLAN.
  2. Check country code and antenna model before approving radio templates.
  3. Align WLAN security, authentication and mobility configuration on APs in the intended roaming domain.
  4. Version-control WLAN security profiles across mobility areas.

Explanation

Correct Answers

C:

This is the corrective intervention because roaming fails when the target WLAN is not compatible with the client's established security association. Confirm its effect using the specified operational recovery check.

D:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: an engineer disables protected management frames to support one old handheld despite a WLAN security requirement that mandates PMF. It is not the targeted repair for this case.

B:

That safeguard would suit a different situation, such as when a retail site uses multiple AP models but a uniform antenna-gain configuration that overstretches permitted EIRP in some areas. It does not specifically prevent this problem.

Question 1075

A wireless floor gets poor coverage behind dense concrete despite high AP transmit power in the corridor. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Relocate or add properly surveyed APs to improve line-of-sight and usable SNR in the obstructed area.
  2. Require predictive and post-deployment validation for material building changes.
  3. Validate 802.11k neighbor reporting where supported by the APs and clients.
  4. Track every SSID-to-profile association in change management.

Explanation

Correct Answers

A:

This is the corrective intervention because building attenuation and obstruction, not merely configuration, create the coverage hole. Confirm its effect using the specified operational recovery check.

B:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

C:

This action fits a different incident: a location-aware application cannot find good roam candidates although coverage overlaps because neighbor information is missing. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a security team wants to disable a previously unused SSID but the site still broadcasts it through a second WLAN profile. It does not specifically prevent this problem.

Question 1076

A VoIP design attempts to solve poor call quality solely by raising AP power while clients still transmit at weak power levels. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Balance AP cell size and client transmit capability and adjust RF design for bidirectional reachability.
  2. Maintain AP placement metadata and a verified floor plan before using location analytics.
  3. Test voice service with actual supported client devices.
  4. Maintain exception expiry dates for devices lacking required WPA capabilities.

Explanation

Correct Answers

A:

This is the corrective intervention because an asymmetric RF link can hear a strong AP even when the AP cannot reliably hear the weaker client. Confirm its effect using the specified operational recovery check.

C:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

B:

This action fits a different incident: a warehouse deployment needs accurate client location, but APs were installed with no stable coordinate or floor map assignment. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when an engineer disables protected management frames to support one old handheld despite a WLAN security requirement that mandates PMF. It does not specifically prevent this problem.

Question 1077

A campus is migrating staff to WPA3-Enterprise but several devices only support WPA2-Enterprise. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Balance AP cell size and client transmit capability and adjust RF design for bidirectional reachability.
  2. Provide approved compatible security service or a planned device upgrade, without falsely claiming WPA3 support on legacy devices.
  3. Inventory supplicant capabilities before tightening WLAN security policies.
  4. Include DHCP lease acceptance in WLAN provisioning checks.

Explanation

Correct Answers

B:

This is the corrective intervention because unsupported authentication and encryption suites prevent association to WPA3-only WLANs. Confirm its effect using the specified operational recovery check.

C:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: a VoIP design attempts to solve poor call quality solely by raising AP power while clients still transmit at weak power levels. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a wireless client can associate to an SSID but never obtains an IPv4 address, while neighboring wired clients obtain DHCP leases. It does not specifically prevent this problem.

Question 1078

A visitor WLAN sends all guest traffic into a production data VLAN because its role mapping uses the employee default role. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Trace the SSID VLAN mapping, trunk path and DHCP relay/scope for the wireless client.
  2. Apply the correct guest role and segmentation mapping with a controlled external egress.
  3. Validate band steering after large RF-policy changes.
  4. Audit role mappings whenever SSIDs or identity policies change.

Explanation

Correct Answers

B:

This is the corrective intervention because the default post-authentication role bypasses the designed guest isolation policy. Confirm its effect using the specified operational recovery check.

D:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

A:

This action fits a different incident: a wireless client can associate to an SSID but never obtains an IPv4 address, while neighboring wired clients obtain DHCP leases. It is not the targeted repair for this case.

C:

That safeguard would suit a different situation, such as when a large office wants better distribution of capable clients between 2.4 and 5 GHz but all steer to 2.4 after a new RF policy. It does not specifically prevent this problem.

Question 1079

An office has a high-density 2.4 GHz WLAN where many IoT sensors use old low basic rates, consuming excessive airtime. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Adjust supported basic rates and client capabilities carefully using a measured site-specific IoT design.
  2. Test legacy-device compatibility before changing minimum/basic rates.
  3. Move the legacy device to an approved separate compatible service or replace it while keeping mandatory PMF on the protected WLAN.
  4. Audit AP coordinates after moves, renovations and device replacements.

Explanation

Correct Answers

A:

This is the corrective intervention because slow basic rates and many management frames consume airtime that higher-rate clients would otherwise use. Confirm its effect using the specified operational recovery check.

B:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

C:

This action fits a different incident: an engineer disables protected management frames to support one old handheld despite a WLAN security requirement that mandates PMF. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a warehouse deployment needs accurate client location, but APs were installed with no stable coordinate or floor map assignment. It does not specifically prevent this problem.

Question 1080

A voice WLAN introduces rapid roaming requirements, but the configuration has no support for the client-compatible 802.11r fast transition mechanism. Which TWO coordinated steps provide the immediate correction and a sensible ongoing safeguard? Select two.

  1. Enable and validate a supported fast-roaming design with compatible clients and authentication infrastructure.
  2. Move the legacy device to an approved separate compatible service or replace it while keeping mandatory PMF on the protected WLAN.
  3. Test 802.11r interoperability rather than enabling it blindly on every SSID.
  4. Document legacy band requirements and decommission dates.

Explanation

Correct Answers

A:

This is the corrective intervention because repeated full key exchanges during roaming can add latency beyond voice application tolerance. Confirm its effect using the specified operational recovery check.

C:

This adds the continuing safeguard so the corrected failure does not recur after the original intervention.

Incorrect Answers

B:

This action fits a different incident: an engineer disables protected management frames to support one old handheld despite a WLAN security requirement that mandates PMF. It is not the targeted repair for this case.

D:

That safeguard would suit a different situation, such as when a warehouse WLAN assigns every radio to 5 GHz, leaving legacy scanners that support only 2.4 GHz unable to join. It does not specifically prevent this problem.
