Question 680

A voice WLAN introduces rapid roaming requirements, but the configuration has no support for the client-compatible 802.11r fast transition mechanism. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Audit role mappings whenever SSIDs or identity policies change.
  2. Test 802.11r interoperability rather than enabling it blindly on every SSID.
  3. Baseline capacity using traffic mix and airtime, not connected-station counts alone.
  4. Rotate shared credentials and audit identity-to-role mappings.

Explanation

Correct Answer

B:

This is a continuing control for the failure mode in which repeated full key exchanges during roaming can add latency beyond voice application tolerance. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

A:

That control is useful for a different failure, such as when a visitor WLAN sends all guest traffic into a production data VLAN because its role mapping uses the employee default role. It would leave the present failure mode insufficiently addressed.

C:

That control is useful for a different failure, such as when a deployment reports high AP client counts but users complain about slow uploads during busy classes. It would leave the present failure mode insufficiently addressed.

D:

That control is useful for a different failure, such as when a lab SSID uses a pre-shared password and the organization needs different access per shared IoT device type. It would leave the present failure mode insufficiently addressed.

Question 681

A location-aware application cannot find good roam candidates although coverage overlaps because neighbor information is missing. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Require predictive and post-deployment validation for material building changes.
  2. Maintain exception expiry dates for devices lacking required WPA capabilities.
  3. Inventory supplicant capabilities before tightening WLAN security policies.
  4. Keep neighbor reporting consistent across the mobility domain.

Explanation

Correct Answer

D:

This is a continuing control for the failure mode in which without neighbor guidance a client may scan more widely before selecting a roam target. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

A:

That control is useful for a different failure, such as when a wireless floor gets poor coverage behind dense concrete despite high AP transmit power in the corridor. It would leave the present failure mode insufficiently addressed.

B:

That control is useful for a different failure, such as when an engineer disables protected management frames to support one old handheld despite a WLAN security requirement that mandates PMF. It would leave the present failure mode insufficiently addressed.

C:

That control is useful for a different failure, such as when a campus is migrating staff to WPA3-Enterprise but several devices only support WPA2-Enterprise. It would leave the present failure mode insufficiently addressed.

Question 682

An engineer interprets 802.11v BSS transition recommendations as a command that always forces a client onto a chosen AP. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Validate channel width against density and spectrum occupancy at each event venue.
  2. Maintain a device band-capability inventory when expanding Wi-Fi 6E coverage.
  3. Survey occupied locations instead of relying on corridor sample points.
  4. Test steering behavior across real device drivers and firmware revisions.

Explanation

Correct Answer

D:

This is a continuing control for the failure mode in which a BSS transition management request guides client selection but clients may decline. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

A:

C:

That control is useful for a different failure, 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 would leave the present failure mode insufficiently addressed.

Question 683

A six-building WLAN uses the same SSID but places client VLANs into different subnets without planning how real-time applications survive moves. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Include routed-subnet boundaries in mobility design reviews.
  2. Use approved channel templates rather than arbitrary channel-number spacing.
  3. Test legacy-device compatibility before changing minimum/basic rates.
  4. Document legacy band requirements and decommission dates.

Explanation

Correct Answer

A:

This is a continuing control for the failure mode in which SSID equality does not itself preserve IP reachability or active sessions across subnet boundaries. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

A:

That control is useful for a different failure, such as when a warehouse deployment needs accurate client location, but APs were installed with no stable coordinate or floor map assignment. It would leave the present failure mode insufficiently addressed.

B:

That control is useful for a different failure, such as when an AP is installed with a directional antenna pointed into a concrete wall rather than the intended warehouse aisle. It would leave the present failure mode insufficiently addressed.

D:

That control is useful for a different failure, 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 would leave the present failure mode insufficiently addressed.
