Question 290

A university WLAN unexpectedly changes channels after radar detection and some client devices disconnect during the move. Which specific corrective design step best meets the stated campus requirement?

  1. Keep compatible service on supported bands and enable 6 GHz only for capable clients with regulatory-compliant security.
  2. Use supported Wi-Fi 6 OFDMA capabilities and an appropriate channel design for simultaneous small transmissions.
  3. Choose an approved alternative channel plan or allow compliant DFS behavior without suppressing mandatory radar protection.
  4. Enable only supported multiuser features while keeping channel and antenna design appropriate to clients.

Explanation

Correct Answer

C:

Choose an approved alternative channel plan or allow compliant DFS behavior without suppressing mandatory radar protection. Dynamic Frequency Selection requires compliant behavior on radar-sensitive channels; disabling the protection is not a safe availability fix. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described 5 ghz dfs channel radar events situation.

Incorrect Answers

A:

Keep compatible service on supported bands and enable 6 GHz only for capable clients with regulatory-compliant security. This instead concerns 6 ghz regulatory and client capabilities. A 6 GHz radio requires supporting hardware, local regulatory permissions and compatible security; existing Wi-Fi connectivity does not imply 6 GHz capability. It would not implement the specifically required change. The immediate problem concerns 5 ghz dfs channel radar events.

B:

Use supported Wi-Fi 6 OFDMA capabilities and an appropriate channel design for simultaneous small transmissions. This instead concerns ofdma scheduling for dense clients. 802.11ax OFDMA can schedule multiple users on resource units, but benefits depend on client capability and RF conditions. It would not implement the specifically required change. The immediate problem concerns 5 ghz dfs channel radar events.

D:

Enable only supported multiuser features while keeping channel and antenna design appropriate to clients. This instead concerns mu-mimo client and ap support. MU-MIMO gains are conditional on AP radio and client capability; a configuration toggle does not create missing physical-layer support. It would not implement the specifically required change. The immediate problem concerns 5 ghz dfs channel radar events.

Question 291

A university WLAN unexpectedly changes channels after radar detection and some client devices disconnect during the move. Following a targeted change, which acceptance test would most directly demonstrate success?

  1. Verify capable test clients discover and associate on 6 GHz while legacy devices still use an approved alternative band.
  2. Verify the AP moves to a permitted channel on a DFS event and clients reconnect in acceptable time.
  3. Measure improved airtime efficiency and aggregate latency with compatible clients under representative concurrency.
  4. Verify compatible client groups gain throughput without regressions for unsupported stations.

Explanation

Correct Answer

B:

Verify the AP moves to a permitted channel on a DFS event and clients reconnect in acceptable time. Dynamic Frequency Selection requires compliant behavior on radar-sensitive channels; disabling the protection is not a safe availability fix. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described 5 ghz dfs channel radar events situation.

Incorrect Answers

A:

Verify capable test clients discover and associate on 6 GHz while legacy devices still use an approved alternative band. This instead concerns 6 ghz regulatory and client capabilities. A 6 GHz radio requires supporting hardware, local regulatory permissions and compatible security; existing Wi-Fi connectivity does not imply 6 GHz capability. It would not establish that this function actually works. The immediate problem concerns 5 ghz dfs channel radar events.

C:

Measure improved airtime efficiency and aggregate latency with compatible clients under representative concurrency. This instead concerns ofdma scheduling for dense clients. 802.11ax OFDMA can schedule multiple users on resource units, but benefits depend on client capability and RF conditions. It would not establish that this function actually works. The immediate problem concerns 5 ghz dfs channel radar events.

Question 292

A university WLAN unexpectedly changes channels after radar detection and some client devices disconnect during the move. The change fails acceptance. What is the safest targeted restoration action?

  1. Revert to known permitted non-DFS channels for affected service areas if DFS moves break required client support.
  2. Restore the previous multi-band WLAN and remove unsupported 6 GHz-only assumptions until endpoint capabilities are validated.
  3. Reinstate the last stable radio configuration if the change harms mixed-generation client compatibility.
  4. Restore conservative radio settings if measured performance remains worse for the actual client population.

Explanation

Correct Answer

A:

Revert to known permitted non-DFS channels for affected service areas if DFS moves break required client support. Dynamic Frequency Selection requires compliant behavior on radar-sensitive channels; disabling the protection is not a safe availability fix. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described 5 ghz dfs channel radar events situation.

Incorrect Answers

B:

Restore the previous multi-band WLAN and remove unsupported 6 GHz-only assumptions until endpoint capabilities are validated. This instead concerns 6 ghz regulatory and client capabilities. A 6 GHz radio requires supporting hardware, local regulatory permissions and compatible security; existing Wi-Fi connectivity does not imply 6 GHz capability. It would not safely roll back the relevant failed change. The immediate problem concerns 5 ghz dfs channel radar events.

C:

Reinstate the last stable radio configuration if the change harms mixed-generation client compatibility. This instead concerns ofdma scheduling for dense clients. 802.11ax OFDMA can schedule multiple users on resource units, but benefits depend on client capability and RF conditions. It would not safely roll back the relevant failed change. The immediate problem concerns 5 ghz dfs channel radar events.

D:

Restore conservative radio settings if measured performance remains worse for the actual client population. This instead concerns mu-mimo client and ap support. MU-MIMO gains are conditional on AP radio and client capability; a configuration toggle does not create missing physical-layer support. It would not safely roll back the relevant failed change. The immediate problem concerns 5 ghz dfs channel radar events.

Question 293

An office AP radio refuses to remain on a selected 5 GHz DFS channel because local radar events trigger regulatory evacuation. The review requires TWO complementary actions: one diagnostic check and one controlled configuration remedy. Select TWO actions that together meet those requirements.

  1. Review client radio and regulatory support, AP band settings, advertised discovery behavior and SSID security.
  2. Review DFS events, local regulatory domain and recent channel changes for the affected AP radios.
  3. Choose supported Wi-Fi 6 OFDMA capabilities and an appropriate channel design for simultaneous small transmissions.
  4. Select an approved alternative channel plan or allow compliant DFS behavior without suppressing mandatory radar protection.

Explanation

Correct Answers

B:

Review DFS events, local regulatory domain and recent channel changes for the affected AP radios. Dynamic Frequency Selection requires compliant behavior on radar-sensitive channels; disabling the protection is not a safe availability fix. This is the required diagnosis or controlled remedy; the other keyed action supplies the complementary role. The decision applies to the described 5 ghz dfs channel radar events situation.

D:

Select an approved alternative channel plan or allow compliant DFS behavior without suppressing mandatory radar protection. Dynamic Frequency Selection requires compliant behavior on radar-sensitive channels; disabling the protection is not a safe availability fix. This is the required diagnosis or controlled remedy; the other keyed action supplies the complementary role. The decision applies to the described 5 ghz dfs channel radar events situation.

Incorrect Answers

A:

Review client radio and regulatory support, AP band settings, advertised discovery behavior and SSID security. This instead concerns 6 ghz regulatory and client capabilities. A 6 GHz radio requires supporting hardware, local regulatory permissions and compatible security; existing Wi-Fi connectivity does not imply 6 GHz capability. It is not one of the requested paired diagnosis and configuration actions. The immediate problem concerns 5 ghz dfs channel radar events.

C:

Choose supported Wi-Fi 6 OFDMA capabilities and an appropriate channel design for simultaneous small transmissions. This instead concerns ofdma scheduling for dense clients. 802.11ax OFDMA can schedule multiple users on resource units, but benefits depend on client capability and RF conditions. It is not one of the requested paired diagnosis and configuration actions. The immediate problem concerns 5 ghz dfs channel radar events.

Question 294

An office AP radio refuses to remain on a selected 5 GHz DFS channel because local radar events trigger regulatory evacuation. After the root cause is confirmed, which narrowly scoped configuration action should be selected?

  1. Maintain compatible service on supported bands and enable 6 GHz only for capable clients with regulatory-compliant security.
  2. Choose supported Wi-Fi 6 OFDMA capabilities and an appropriate channel design for simultaneous small transmissions.
  3. Select an approved alternative channel plan or allow compliant DFS behavior without suppressing mandatory radar protection.
  4. Activate only supported multiuser features while keeping channel and antenna design appropriate to clients.

Explanation

Correct Answer

C:

Select an approved alternative channel plan or allow compliant DFS behavior without suppressing mandatory radar protection. Dynamic Frequency Selection requires compliant behavior on radar-sensitive channels; disabling the protection is not a safe availability fix.

Question 295

An office AP radio refuses to remain on a selected 5 GHz DFS channel because local radar events trigger regulatory evacuation. A deployment job reports success. Which observed result would actually validate the affected service?

  1. Confirm capable test clients discover and associate on 6 GHz while legacy devices still use an approved alternative band.
  2. Confirm the AP moves to a permitted channel on a DFS event and clients reconnect in acceptable time.
  3. Quantify improved airtime efficiency and aggregate latency with compatible clients under representative concurrency.
  4. Confirm compatible client groups gain throughput without regressions for unsupported stations.

Question 297

A campus enables a 6 GHz WLAN but older clients only support 2.4 and 5 GHz and cannot see the new SSID. Which investigation would best isolate the immediate network dependency?

  1. Inspect client radio and regulatory support, AP band settings, advertised discovery behavior and SSID security.
  2. Inspect 802.11ax client support, airtime efficiency and scheduler behavior under comparable small-packet load.
  3. Inspect AP antenna capability, client MU-MIMO support and actual airtime statistics rather than relying on feature names.
  4. Inspect client band support, band-selection decisions, RSSI and per-band channel utilization.

Explanation

Correct Answer

A:

Inspect client radio and regulatory support, AP band settings, advertised discovery behavior and SSID security. A 6 GHz radio requires supporting hardware, local regulatory permissions and compatible security; existing Wi-Fi connectivity does not imply 6 GHz capability. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described 6 ghz regulatory and client capabilities situation.

Incorrect Answers

B:

Inspect 802.11ax client support, airtime efficiency and scheduler behavior under comparable small-packet load.
