Question 860
A remote branch prioritizes real-time collaboration but clients can mark any traffic as high priority. Which misconception is most likely to obstruct a correct fix?
- Remove all QoS classification so both applications compete without any prioritization
- Accept every client DSCP value as an approved enterprise priority
- Set an AP's channel width to maximum and assume metal obstruction ceases to matter
- Assume one TCP flow will saturate the sum of every ECMP uplink rate
Explanation
Correct Answer
B:Untrusted endpoints can abuse premium queues. User-provided priority tags must not override business policy.
Incorrect Answers
A:Eliminating controls may worsen low-latency traffic service. By contrast, untrusted endpoints can abuse premium queues.
C:Channel width cannot remove physical shadowing. In this situation, untrusted endpoints can abuse premium queues.
D:Hash-based load balancing typically pins a flow to one path. It would not resolve the documented symptom; untrusted endpoints can abuse premium queues.
Question 861
A remote branch prioritizes real-time collaboration but clients can mark any traffic as high priority. What precaution is most important before the change is expanded?
- Implement a tested shaping policy with emergency backup exceptions
- Validate client capability and latency during a phased channel-plan change

- Pilot basic-rate changes with the oldest approved client group
Explanation
Correct Answer
C:Excessive priority reservation can starve needed background traffic. The effective treatment shows whether trust rules are applied.
Incorrect Answers

B:A new width can affect older devices and regulatory choices. By contrast, excessive priority reservation can starve needed background traffic.
D:Incompatible edge devices can lose service after aggressive tuning. It would not resolve the documented symptom; excessive priority reservation can starve needed background traffic.
Question 862
A classroom AP sees high retransmissions despite low reported data volume. Which configuration decision most directly resolves the situation?
- Review antenna placement, multipath and fallback coverage around moving obstructions
- Investigate RF SNR, channel contention and client rates instead of assuming spare airtime
- Reassess minimum rates, security mode and band/channel compatibility for supported legacy clients
- Evaluate narrower channels and improved reuse based on measured co-channel occupancy
Explanation
Correct Answer
B:Repeated failed frames consume radio time even when payload throughput is low. The measurements distinguish interference from insufficient capacity.
Incorrect Answers
A:Temporary shielding can change signal-to-noise and retransmission needs. Here, however, repeated failed frames consume radio time even when payload throughput is low.
C:A faster design can exclude hardware without newer radio features. By contrast, repeated failed frames consume radio time even when payload throughput is low.
D:Wide channels can reduce the number of nonoverlapping cells. The relevant technical distinction is that repeated failed frames consume radio time even when payload throughput is low.
Question 863
A classroom AP sees high retransmissions despite low reported data volume. Which check most directly demonstrates the desired network behavior?
- Compare retries, noise floor and channel busy time for affected clients
- Measure video bitrate, dropped frames and matched QoS class during the shaper interval
- Measure interactive latency and backup throughput during representative simultaneous load
- Correlate voice/video quality with burst counters and per-queue occupancy
Explanation
Correct Answer
A:The measurements distinguish interference from insufficient capacity. Repeated failed frames consume radio time even when payload throughput is low.
Incorrect Answers
B:Per-class evidence identifies the overrestricted traffic class. The relevant technical distinction is that the measurements distinguish interference from insufficient capacity.
C:Both service classes should remain within business targets. Here, however, the measurements distinguish interference from insufficient capacity.
D:Fine-grained evidence exposes transient congestion. In this situation, the measurements distinguish interference from insufficient capacity.
Question 864
A classroom AP sees high retransmissions despite low reported data volume. Which assumption would be most misleading when investigating this situation?
- Assume a low five-minute average utilization guarantees zero short-term queue loss
- Assume one TCP flow will saturate the sum of every ECMP uplink rate
- Accept every client DSCP value as an approved enterprise priority
- Assume low useful throughput always means the AP is underutilized
Explanation
Correct Answer
D:Failed transmissions can occupy most of the channel. Repeated failed frames consume radio time even when payload throughput is low.
Incorrect Answers
A:Averages can hide momentary saturation. It would not resolve the documented symptom; failed transmissions can occupy most of the channel.
B:Hash-based load balancing typically pins a flow to one path. In this situation, failed transmissions can occupy most of the channel.
C:Untrusted endpoints can abuse premium queues. Here, however, failed transmissions can occupy most of the channel.
Question 865
A classroom AP sees high retransmissions despite low reported data volume. Which safeguard best reduces the deployment risk in this case?
- Implement a tested shaping policy with emergency backup exceptions
- Record contracted QoS behavior and test failover through secondary carriers
- Size a surviving uplink for the largest critical single-flow demand
- Address interference first and then retest application latency
Explanation
Correct Answer
D:A bandwidth upgrade cannot fix the RF collision environment. The measurements distinguish interference from insufficient capacity.
Incorrect Answers
A:Performance tuning should not prevent essential recovery jobs. It would not resolve the documented symptom; a bandwidth upgrade cannot fix the RF collision environment.
B:Backup networks may not honor the same traffic classes. By contrast, a bandwidth upgrade cannot fix the RF collision environment.
C:Aggregate capacity does not guarantee per-flow throughput. In this situation, a bandwidth upgrade cannot fix the RF collision environment.
Question 866
A campus uses a single 1 Gbps uplink for several APs and peak combined traffic exceeds that link. What is the most appropriate first technical change?
- Capacity-plan QoS classes for the surviving link and test degraded-path congestion
- Evaluate narrower channels and improved reuse based on measured co-channel occupancy
- Size and aggregate uplinks according to measured AP demand and switch capability
- Review per-flow hashing and consider supported aggregation or application-level distribution
Explanation
Correct Answer
C:A shared physical bottleneck can cap total WLAN performance. Correlation identifies the wired bottleneck behind a healthy WLAN signal.
Incorrect Answers
A:Redundancy reduces available bandwidth during a failure. The relevant technical distinction is that a shared physical bottleneck can cap total WLAN performance.
B:Wide channels can reduce the number of nonoverlapping cells. It would not resolve the documented symptom; a shared physical bottleneck can cap total WLAN performance.
D:A single flow may not spread across multiple equal-cost paths. By contrast, a shared physical bottleneck can cap total WLAN performance.
Question 867
A campus uses a single 1 Gbps uplink for several APs and peak combined traffic exceeds that link. Which observation would best verify that the intended behavior is working?
- Compare channel utilization and client connection success before and after rate tuning
- Correlate voice/video quality with burst counters and per-queue occupancy
- Compare combined AP traffic, uplink saturation and queue drops during a busy class
- Measure SNR, retry rates and application latency along the equipment routes
Explanation
Correct Answer
C:Correlation identifies the wired bottleneck behind a healthy WLAN signal. A shared physical bottleneck can cap total WLAN performance.
Incorrect Answers
A:Higher rates are useful only when edge devices still operate. Here, however, correlation identifies the wired bottleneck behind a healthy WLAN signal.
B:Fine-grained evidence exposes transient congestion. The relevant technical distinction is that correlation identifies the wired bottleneck behind a healthy WLAN signal.
D:A moving RF survey captures the conditions that cause jitter. By contrast, correlation identifies the wired bottleneck behind a healthy WLAN signal.
Question 868
A campus uses a single 1 Gbps uplink for several APs and peak combined traffic exceeds that link. Which belief about the configuration should the team reject?
- Replace core routing tables to fix a radio capability mismatch

- Assume a local DSCP tag guarantees identical handling in every carrier network
- Set every traffic class to the highest queue priority
Explanation
Correct Answer
B:Radio power cannot change the uplink's physical rate. A shared physical bottleneck can cap total WLAN performance.
Incorrect Answers
A:Wired routes cannot make a client support unsupported WLAN settings. Here, however, radio power cannot change the uplink's physical rate.
C:External providers apply their own QoS policies. The relevant technical distinction is that radio power cannot change the uplink's physical rate.
D:If all packets are premium, prioritization has no value. In this situation, radio power cannot change the uplink's physical rate.
Question 869
A campus uses a single 1 Gbps uplink for several APs and peak combined traffic exceeds that link. What should be included in the rollout plan to limit a foreseeable failure?
- Test the upgraded path under multiple concurrent AP workloads
- Address interference first and then retest application latency
- Limit mis-marking by untrusted clients and document class boundaries
- Pilot basic-rate changes with the oldest approved client group
Explanation
Correct Answer

Question 870
A campus switch has a traffic shaper that reduces video quality even though voice remains clear. What should the network engineer do to address this requirement?
- Review per-flow hashing and consider supported aggregation or application-level distribution
- Coordinate the provider's supported QoS class mapping and local ingress/egress policy
- Review minimum/basic rates with measured coverage and legacy client requirements
- Review class allocation and rate limits for video and voice separately
Explanation
Correct Answer
D:Application priorities and shaping limits need proportionate capacity. Per-class evidence identifies the overrestricted traffic class.
Incorrect Answers
A:A single flow may not spread across multiple equal-cost paths. By contrast, application priorities and shaping limits need proportionate capacity.
B:End-to-end prioritization depends on preserved or translated markings. In this situation, application priorities and shaping limits need proportionate capacity.
C:Slow management traffic consumes disproportionate airtime in dense cells. It would not resolve the documented symptom; application priorities and shaping limits need proportionate capacity.
