Question 80

A voice WLAN introduces rapid roaming requirements, but the configuration has no support for the client-compatible 802.11r fast transition mechanism. Which immediate engineering change most directly addresses this issue?

  1. Tune supported band-preference or steering settings based on client capabilities and coverage evidence.
  2. Enable and validate a supported fast-roaming design with compatible clients and authentication infrastructure.
  3. Validate 802.11k neighbor reporting where supported by the APs and clients.
  4. Measure airtime utilization, per-client throughput and channel contention rather than relying on association counts.

Explanation

Correct Answer

B:

The underlying issue is that repeated full key exchanges during roaming can add latency beyond voice application tolerance. This intervention addresses that cause directly. A useful result to confirm is: voice clients roam with acceptable handoff time and retained security.

Incorrect Answers

A:

This is suited to a different condition, 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. The reported fault instead arises because repeated full key exchanges during roaming can add latency beyond voice application tolerance.

C:

This is suited to a different condition, such as when a location-aware application cannot find good roam candidates although coverage overlaps because neighbor information is missing. The reported fault instead arises because repeated full key exchanges during roaming can add latency beyond voice application tolerance.

D:

This is suited to a different condition, such as when a deployment reports high AP client counts but users complain about slow uploads during busy classes. The reported fault instead arises because repeated full key exchanges during roaming can add latency beyond voice application tolerance.

Question 81

A location-aware application cannot find good roam candidates although coverage overlaps because neighbor information is missing. Which immediate engineering change most directly addresses this issue?

  1. Enable and validate a supported fast-roaming design with compatible clients and authentication infrastructure.
  2. Adjust supported basic rates and client capabilities carefully using a measured site-specific IoT design.
  3. Remove the SSID from all unintended broadcast profiles and validate the permitted networks.
  4. Validate 802.11k neighbor reporting where supported by the APs and clients.

Explanation

Correct Answer

D:

The underlying issue is that without neighbor guidance a client may scan more widely before selecting a roam target. This intervention addresses that cause directly. A useful result to confirm is: supported clients receive useful neighbor reports and roam efficiently.

Incorrect Answers

A:

This is suited to a different condition, 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. The reported fault instead arises because without neighbor guidance a client may scan more widely before selecting a roam target.

B:

This is suited to a different condition, such as when an office has a high-density 2.4 GHz WLAN where many IoT sensors use old low basic rates, consuming excessive airtime. The reported fault instead arises because without neighbor guidance a client may scan more widely before selecting a roam target.

C:

This is suited to a different condition, such as when a security team wants to disable a previously unused SSID but the site still broadcasts it through a second WLAN profile. The reported fault instead arises because without neighbor guidance a client may scan more widely before selecting a roam target.

Question 82

An engineer interprets 802.11v BSS transition recommendations as a command that always forces a client onto a chosen AP. Which immediate engineering change most directly addresses this issue?

  1. Design steering with client support and behavior in mind rather than assuming the AP unilaterally controls associations.
  2. Validate the server certificate trust chain, name and validity against client supplicant policy.
  3. Define the correct client mobility and session continuity architecture for inter-building transitions.
  4. Apply the correct guest role and segmentation mapping with a controlled external egress.

Explanation

Correct Answer

A:

The underlying issue is that a BSS transition management request guides client selection but clients may decline. This intervention addresses that cause directly. A useful result to confirm is: client distributions improve under supported steering without depending on mandatory compliance.

Incorrect Answers

B:

This is suited to a different condition, such as when an employee WLAN uses EAP-TLS and clients fail immediately after a RADIUS server certificate renewal. The reported fault instead arises because a BSS transition management request guides client selection but clients may decline.

C:

This is suited to a different condition, such as when a six-building WLAN uses the same SSID but places client VLANs into different subnets without planning how real-time applications survive moves. The reported fault instead arises because a BSS transition management request guides client selection but clients may decline.

D:

This is suited to a different condition, such as when a visitor WLAN sends all guest traffic into a production data VLAN because its role mapping uses the employee default role. The reported fault instead arises because a BSS transition management request guides client selection but clients may decline.

Question 83

A six-building WLAN uses the same SSID but places client VLANs into different subnets without planning how real-time applications survive moves. Which immediate engineering change most directly addresses this issue?

  1. Define the correct client mobility and session continuity architecture for inter-building transitions.
  2. Provide approved compatible security service or a planned device upgrade, without falsely claiming WPA3 support on legacy devices.
  3. Base enforcement on validated user or device attributes and assigned access role, not the SSID name alone.
  4. Align WLAN security, authentication and mobility configuration on APs in the intended roaming domain.

Explanation

Correct Answer

A:

The underlying issue is that SSID equality does not itself preserve IP reachability or active sessions across subnet boundaries. This intervention addresses that cause directly. A useful result to confirm is: a supported client moves across buildings and retains the intended connectivity behavior.

Incorrect Answers

B:

This is suited to a different condition, such as when a campus is migrating staff to WPA3-Enterprise but several devices only support WPA2-Enterprise. The reported fault instead arises because SSID equality does not itself preserve IP reachability or active sessions across subnet boundaries.

C:

This is suited to a different condition, such as when a wireless role design assumes connecting to the corporate SSID always grants internal network privileges even when a guest certificate authenticates. The reported fault instead arises because SSID equality does not itself preserve IP reachability or active sessions across subnet boundaries.

D:

This is suited to a different condition, such as when a warehouse handheld disconnects while roaming between APs because its target radios have different SSID security settings. The reported fault instead arises because SSID equality does not itself preserve IP reachability or active sessions across subnet boundaries.

Question 84

A lab SSID uses a pre-shared password and the organization needs different access per shared IoT device type. Which immediate engineering change most directly addresses this issue?

  1. Move the legacy device to an approved separate compatible service or replace it while keeping mandatory PMF on the protected WLAN.
  2. Examine probe, authentication and association negotiation rather than assuming hiding an SSID prevents discovery or guarantees security.
  3. Use nonoverlapping channels supported by the local regulatory domain, such as a verified 1/6/11 plan where appropriate.
  4. Use supported identity-aware or multi-PSK device-group mapping with separate policies.

Explanation

Correct Answer

D:

The underlying issue is that a single common PSK provides insufficient per-class segmentation without additional controls. This intervention addresses that cause directly. A useful result to confirm is: approved device types enter only their assigned roles and unauthorized types are denied.

Incorrect Answers

A:

This is suited to a different condition, such as when an engineer disables protected management frames to support one old handheld despite a WLAN security requirement that mandates PMF. The reported fault instead arises because a single common PSK provides insufficient per-class segmentation without additional controls.

B:

This is suited to a different condition, such as when a client station repeatedly attempts to join a hidden SSID but technicians attribute its failure solely to low signal. The reported fault instead arises because a single common PSK provides insufficient per-class segmentation without additional controls.

C:

This is suited to a different condition, such as when a site uses overlapping 2.4 GHz channels 1 and 3 believing their numbers are far enough apart. The reported fault instead arises because a single common PSK provides insufficient per-class segmentation without additional controls.

Question 85

An AP is installed with a directional antenna pointed into a concrete wall rather than the intended warehouse aisle. Which immediate engineering change most directly addresses this issue?

  1. Reorient or replace the antenna according to the validated coverage design.
  2. Enable and validate a supported fast-roaming design with compatible clients and authentication infrastructure.
  3. Remove the SSID from all unintended broadcast profiles and validate the permitted networks.
  4. Provide an appropriate supported 5 GHz service for legacy clients instead of assuming 6 GHz backward compatibility.

Explanation

Correct Answer

A:

The underlying issue is that a directional antenna focuses radiated energy in the wrong physical direction. This intervention addresses that cause directly. A useful result to confirm is: survey measurements show usable SNR along the aisle with reduced unnecessary spill.

Incorrect Answers

B:

This is suited to a different condition, 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. The reported fault instead arises because a directional antenna focuses radiated energy in the wrong physical direction.

C:

This is suited to a different condition, such as when a security team wants to disable a previously unused SSID but the site still broadcasts it through a second WLAN profile. The reported fault instead arises because a directional antenna focuses radiated energy in the wrong physical direction.

D:

This is suited to a different condition, such as when an office installs a new 6 GHz-capable AP, but an older 802.11ac laptop cannot detect the dedicated 6 GHz-only SSID. The reported fault instead arises because a directional antenna focuses radiated energy in the wrong physical direction.

Question 86

The campus WLAN's APs transmit at maximum power, creating very large overlapping cells and sticky client behavior. Which immediate engineering change most directly addresses this issue?

  1. Apply the correct guest role and segmentation mapping with a controlled external egress.
  2. Tune transmit power and cell overlap using RF measurements and the client's roaming behavior.
  3. Use nonoverlapping channels supported by the local regulatory domain, such as a verified 1/6/11 plan where appropriate.
  4. Base enforcement on validated user or device attributes and assigned access role, not the SSID name alone.

Explanation

Correct Answer

B:

The underlying issue is that oversized high-power cells can encourage clients to remain associated beyond a useful data-rate boundary. This intervention addresses that cause directly. A useful result to confirm is: clients move to stronger APs at appropriate locations and throughput improves.

Incorrect Answers

A:

This is suited to a different condition, such as when a visitor WLAN sends all guest traffic into a production data VLAN because its role mapping uses the employee default role. The reported fault instead arises because oversized high-power cells can encourage clients to remain associated beyond a useful data-rate boundary.

C:

This is suited to a different condition, such as when a site uses overlapping 2.4 GHz channels 1 and 3 believing their numbers are far enough apart. The reported fault instead arises because oversized high-power cells can encourage clients to remain associated beyond a useful data-rate boundary.

D:

This is suited to a different condition, such as when a wireless role design assumes connecting to the corporate SSID always grants internal network privileges even when a guest certificate authenticates. The reported fault instead arises because oversized high-power cells can encourage clients to remain associated beyond a useful data-rate boundary.

Question 87

A security team wants to disable a previously unused SSID but the site still broadcasts it through a second WLAN profile. Which immediate engineering change most directly addresses this issue?

  1. Examine probe, authentication and association negotiation rather than assuming hiding an SSID prevents discovery or guarantees security.
  2. Remove the SSID from all unintended broadcast profiles and validate the permitted networks.
  3. Trace the SSID VLAN mapping, trunk path and DHCP relay/scope for the wireless client.
  4. Revisit AP density, power and channel reuse instead of adding yet more unmanaged cells.

Explanation

Correct Answer

B:

The underlying issue is that duplicate or inherited WLAN profiles can continue advertising a supposedly retired SSID. This intervention addresses that cause directly. A useful result to confirm is: beacon scans no longer reveal the retired SSID and approved SSIDs remain available.

Incorrect Answers

A:

This is suited to a different condition, such as when a client station repeatedly attempts to join a hidden SSID but technicians attribute its failure solely to low signal. The reported fault instead arises because duplicate or inherited WLAN profiles can continue advertising a supposedly retired SSID.

C:

This is suited to a different condition, such as when a wireless client can associate to an SSID but never obtains an IPv4 address, while neighboring wired clients obtain DHCP leases. The reported fault instead arises because duplicate or inherited WLAN profiles can continue advertising a supposedly retired SSID.

D:

This is suited to a different condition, such as when an event venue experiences persistent poor throughput after deploying many extra APs in close proximity on unchanged channels. The reported fault instead arises because duplicate or inherited WLAN profiles can continue advertising a supposedly retired SSID.

Question 88

A deployment reports high AP client counts but users complain about slow uploads during busy classes. Which immediate engineering change most directly addresses this issue?

  1. Define the correct client mobility and session continuity architecture for inter-building transitions.
  2. Measure airtime utilization, per-client throughput and channel contention rather than relying on association counts.
  3. Provide a carefully bounded 2.4 GHz service or upgrade the scanners, based on supported radio capabilities.
  4. Apply the correct guest role and segmentation mapping with a controlled external egress.

Explanation

Correct Answer

B:

The underlying issue is that client count alone does not describe real capacity or whether uplink airtime is overloaded. This intervention addresses that cause directly. A useful result to confirm is: representative uploads meet target throughput under peak occupancy.

Incorrect Answers

A:

This is suited to a different condition, such as when a six-building WLAN uses the same SSID but places client VLANs into different subnets without planning how real-time applications survive moves. The reported fault instead arises because client count alone does not describe real capacity or whether uplink airtime is overloaded.

C:

This is suited to a different condition, such as when a warehouse WLAN assigns every radio to 5 GHz, leaving legacy scanners that support only 2.4 GHz unable to join. The reported fault instead arises because client count alone does not describe real capacity or whether uplink airtime is overloaded.

D:

This is suited to a different condition, such as when a visitor WLAN sends all guest traffic into a production data VLAN because its role mapping uses the employee default role. The reported fault instead arises because client count alone does not describe real capacity or whether uplink airtime is overloaded.

Question 89

A site uses overlapping 2.4 GHz channels 1 and 3 believing their numbers are far enough apart. Which immediate engineering change most directly addresses this issue?

  1. Align WLAN security, authentication and mobility configuration on APs in the intended roaming domain.
  2. Replan channels and DFS use according to regulatory requirements and service tolerance, never disable mandatory radar protection.
  3. Move the legacy device to an approved separate compatible service or replace it while keeping mandatory PMF on the protected WLAN.
  4. Use nonoverlapping channels supported by the local regulatory domain, such as a verified 1/6/11 plan where appropriate.

Explanation

Correct Answer

D:

The underlying issue is that closely spaced 2.4 GHz channels overlap spectrally and interfere with one another. This intervention addresses that cause directly. A useful result to confirm is: spectrum scans show reduced adjacent-channel interference after replan.

Incorrect Answers

A:

This is suited to a different condition, such as when a warehouse handheld disconnects while roaming between APs because its target radios have different SSID security settings. The reported fault instead arises because closely spaced 2.4 GHz channels overlap spectrally and interfere with one another.

B:

This is suited to a different condition, such as when an AP shows DFS radar events and channels change during business hours, interrupting some clients. The reported fault instead arises because closely spaced 2.4 GHz channels overlap spectrally and interfere with one another.

C:

This is suited to a different condition, such as when an engineer disables protected management frames to support one old handheld despite a WLAN security requirement that mandates PMF. The reported fault instead arises because closely spaced 2.4 GHz channels overlap spectrally and interfere with one another.

Question 90

A wireless client can associate to an SSID but never obtains an IPv4 address, while neighboring wired clients obtain DHCP leases. Which immediate engineering change most directly addresses this issue?

  1. Adjust supported basic rates and client capabilities carefully using a measured site-specific IoT design.
  2. Enable and validate a supported fast-roaming design with compatible clients and authentication infrastructure.
  3. Tune transmit power and cell overlap using RF measurements and the client's roaming behavior.
  4. Trace the SSID VLAN mapping, trunk path and DHCP relay/scope for the wireless client.

Explanation

Correct Answer

D:

The underlying issue is that association success verifies radio access, not correct DHCP transport into the client subnet. This intervention addresses that cause directly. A useful result to confirm is: the client receives correct IP settings through the intended WLAN and VLAN path.

Incorrect Answers

A:

This is suited to a different condition, such as when an office has a high-density 2.4 GHz WLAN where many IoT sensors use old low basic rates, consuming excessive airtime. The reported fault instead arises because association success verifies radio access, not correct DHCP transport into the client subnet.

B:

This is suited to a different condition, 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. The reported fault instead arises because association success verifies radio access, not correct DHCP transport into the client subnet.
