Question 890
A school improves average Wi-Fi throughput but several older laptops stop associating. What is the most appropriate first technical change?
- Evaluate narrower channels and improved reuse based on measured co-channel occupancy
- Reassess minimum rates, security mode and band/channel compatibility for supported legacy clients
- Apply supported WMM and end-to-end QoS marking for voice while maintaining normal data policy
- Investigate RF SNR, channel contention and client rates instead of assuming spare airtime
Explanation
Correct Answer
B:A faster design can exclude hardware without newer radio features. The exact mismatch identifies what optimization broke compatibility.
Incorrect Answers
A:Wide channels can reduce the number of nonoverlapping cells. In this situation, a faster design can exclude hardware without newer radio features.
C:Priority handling can reduce voice delay under contention. By contrast, a faster design can exclude hardware without newer radio features.
D:Repeated failed frames consume radio time even when payload throughput is low. It would not resolve the documented symptom; a faster design can exclude hardware without newer radio features.

Question 892
A school improves average Wi-Fi throughput but several older laptops stop associating. Which belief about the configuration should the team reject?
- Replace core routing tables to fix a radio capability mismatch
- Increase each AP's transmit power and expect the wired uplink capacity to grow
- Set every traffic class to the highest queue priority
- Maximize advertised transmit power instead of addressing long low-rate airtime use
Explanation
Correct Answer
A:Wired routes cannot make a client support unsupported WLAN settings. A faster design can exclude hardware without newer radio features.
Incorrect Answers
B:Radio power cannot change the uplink's physical rate. By contrast, wired routes cannot make a client support unsupported WLAN settings.
C:If all packets are premium, prioritization has no value. Here, however, wired routes cannot make a client support unsupported WLAN settings.
D:More signal does not remove the airtime cost of slow transmissions. The relevant technical distinction is that wired routes cannot make a client support unsupported WLAN settings.
Question 893
A school improves average Wi-Fi throughput but several older laptops stop associating. What should be included in the rollout plan to limit a foreseeable failure?
- Pilot basic-rate changes with the oldest approved client group
- Provide a restricted compatible SSID or managed replacement plan
- Rebalance queues on a pilot interface and verify other application classes
- Size a surviving uplink for the largest critical single-flow demand
Explanation
Correct Answer
B:Performance improvements should include a supported transition for older devices. The exact mismatch identifies what optimization broke compatibility.
Incorrect Answers
A:Incompatible edge devices can lose service after aggressive tuning. The relevant technical distinction is that performance improvements should include a supported transition for older devices.
C:Fixing one class should not starve another. Here, however, performance improvements should include a supported transition for older devices.
D:Aggregate capacity does not guarantee per-flow throughput. In this situation, performance improvements should include a supported transition for older devices.
Question 894
A campus configures high-priority voice queues but suffers packet loss after one distribution link fails. What should the network engineer do to address this requirement?
- Evaluate supported band steering and cell design without excluding legacy clients
- Capacity-plan QoS classes for the surviving link and test degraded-path congestion
- Schedule or shape backup traffic with an approved lower-priority class
- Review antenna placement, multipath and fallback coverage around moving obstructions
Explanation
Correct Answer
B:Redundancy reduces available bandwidth during a failure. Failure-mode performance is the relevant acceptance gate.
Incorrect Answers
A:Moving compatible users can reduce 2.4 GHz contention. Here, however, redundancy reduces available bandwidth during a failure.
C:Noncritical bulk transfers should yield when interactive demand rises. In this situation, redundancy reduces available bandwidth during a failure.
D:Temporary shielding can change signal-to-noise and retransmission needs. It would not resolve the documented symptom; redundancy reduces available bandwidth during a failure.
Question 895
A campus configures high-priority voice queues but suffers packet loss after one distribution link fails. What should the team inspect to confirm the result?
- Compare failing client capability against changed WLAN parameters and association logs
- Compare next-hop counters for many independent flows versus one transfer
- Measure voice jitter, queue drops and backup-link utilization during controlled failover
- Test a live class, bulk stream and ordinary browsing under the revised policy
Explanation
Correct Answer
C:Failure-mode performance is the relevant acceptance gate. Redundancy reduces available bandwidth during a failure.
Incorrect Answers
A:The exact mismatch identifies what optimization broke compatibility. In this situation, failure-mode performance is the relevant acceptance gate.
B:The contrast demonstrates the distribution granularity. By contrast, failure-mode performance is the relevant acceptance gate.
D:Three service types reveal whether the change is appropriately targeted. It would not resolve the documented symptom; failure-mode performance is the relevant acceptance gate.
Question 896
A campus configures high-priority voice queues but suffers packet loss after one distribution link fails. Which misconception is most likely to obstruct a correct fix?
- Assume a wider channel always improves total campus throughput regardless of density
- Increase each AP's transmit power and expect the wired uplink capacity to grow
- Assume nominal aggregate dual-link bandwidth remains unchanged after one link fails
- Disable 2.4 GHz immediately for all devices without checking scanner support
Explanation
Correct Answer
C:Losing a physical link reduces available capacity. Redundancy reduces available bandwidth during a failure.
Incorrect Answers
A:High overlap can cancel any per-link bandwidth advantage. The relevant technical distinction is that losing a physical link reduces available capacity.
B:Radio power cannot change the uplink's physical rate. By contrast, losing a physical link reduces available capacity.
D:Single-band legacy devices may lose connectivity. It would not resolve the documented symptom; losing a physical link reduces available capacity.
Question 897
A campus configures high-priority voice queues but suffers packet loss after one distribution link fails. What precaution is most important before the change is expanded?
- Pilot basic-rate changes with the oldest approved client group
- Validate client capability and latency during a phased channel-plan change
- Provide a restricted compatible SSID or managed replacement plan
- Define noncritical shedding and recovery criteria for failover
Explanation
Correct Answer

Question 898
A university uses wireless traffic shaping to cap student video, but real-time learning sessions are also throttled. Which configuration decision most directly resolves the situation?
- Define trust boundaries for DSCP markings and remark untrusted edge traffic
