Question 360

At the Thornfield campus network, a switch shows low average interface utilization yet bursty storage traffic suffers intermittent loss. Which ongoing control best prevents this issue from recurring?

  1. Track IGMP group and querier health as media demand grows
  2. Review optic health and loss budgets during fiber maintenance
  3. Check MST region digests during switch onboarding
  4. Monitor peak queue usage and burst indicators

Explanation

Correct Answer

D:

This control works beyond the initial remediation because it requires the team to monitor peak queue usage and burst indicators. This result addresses the stated challenge at the Thornfield campus network.

Incorrect Answers

A:

without valid membership tracking multicast can be flooded to unrelated ports. The offered alternative applies that mechanism: Track IGMP group and querier health as media demand grows. The reported facts point to a different controlling condition: it requires the team to monitor peak queue usage and burst indicators. The alternative does not directly settle the required recurrence control.

B:

Review optic health and loss budgets during fiber maintenance. Its technical scope is explained by: insufficient optical signal can cause link drops even with correct VLAN and routing setup. In this question, the decisive issue is: it requires the team to monitor peak queue usage and burst indicators. That is why the offered option is not the most direct recurrence control.

C:

Check MST region digests during switch onboarding. The reported problem is governed by this different mechanism: it requires the team to monitor peak queue usage and burst indicators. The offered choice would not address that particular recurrence control directly.

Question 361

At the Highbridge energy utility, one network path has low throughput and rising frame check sequence errors while neighboring links are clean. Which implementation choice best addresses the situation?

  1. Check both endpoint and switch negotiation mode and return to a supported compatible configuration
  2. Inspect physical error counters and validate cable optic and port conditions on the suspect hop
  3. Inspect total and per-port PoE consumption and correct the power budget shortfall
  4. Inspect the VRF route tables route leaking and interface memberships then remove the unauthorized exchange

Explanation

Correct Answer

B:

Inspect physical error counters and validate cable optic and port conditions on the suspect hop is the best response because corrupt frames require retransmission even when link speed appears correctly negotiated. A focused validation would establish that a known-good cable test removes CRC growth and restores expected throughput. This result addresses the stated challenge at the Highbridge energy utility.

Incorrect Answers

A:

Check both endpoint and switch negotiation mode and return to a supported compatible configuration. Its technical scope is explained by: mismatched link parameters can create retransmissions and degraded forwarding even with link up, the required evidence must show that the negotiated link passes an error-free throughput validation. In this question, the decisive issue is: corrupt frames require retransmission even when link speed appears correctly negotiated. That is why the offered option is not the most direct implementation.

C:

Inspect total and per-port PoE consumption and correct the power budget shortfall. This option is based on the following distinct technical behavior: exhausted shared PoE power can remove power from otherwise healthy endpoints; a passing acceptance check would show that all approved powered devices remain online at their peak expected draw. The present question instead depends on this mechanism: corrupt frames require retransmission even when link speed appears correctly negotiated. That difference matters for the requested implementation.

D:

a poorly scoped route import can undermine segmentation without changing physical VLANs. The offered alternative applies that mechanism: Inspect the VRF route tables route leaking and interface memberships then remove the unauthorized exchange. The reported facts point to a different controlling condition: corrupt frames require retransmission even when link speed appears correctly negotiated. The alternative does not directly settle the required implementation.

Question 362

At the Highbridge energy utility, one network path has low throughput and rising frame check sequence errors while neighboring links are clean. What risk should the team identify as the primary issue?

  1. An overly aggressive queue allocation can starve another important traffic class
  2. Untracked changes make a fleet-wide regression difficult to diagnose and reverse safely
  3. Improper physical negotiation or defective medium can corrupt Ethernet frames despite an up state
  4. Corrupt frames require retransmission even when link speed appears correctly negotiated

Explanation

Correct Answer

D:

The architectural weakness is that corrupt frames require retransmission even when link speed appears correctly negotiated. It can be addressed through the controlled change to inspect physical error counters and validate cable optic and port conditions on the suspect hop. This result addresses the stated challenge at the Highbridge energy utility.

Incorrect Answers

A:

The option states: An overly aggressive queue allocation can starve another important traffic class. The source describes its associated mechanism as: an overly aggressive queue allocation can starve another important traffic class, rather than merely a monitoring or presentation issue. By contrast, the current situation is governed by: it requires the team to trend physical-layer counters and schedule corrective replacement. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

B:

Untracked changes make a fleet-wide regression difficult to diagnose and reverse safely. The present question instead depends on this mechanism: it requires the team to trend physical-layer counters and schedule corrective replacement. That difference matters for the requested root-cause explanation.

C:

The offered alternative states: Improper physical negotiation or defective medium can corrupt Ethernet frames despite an up state. The reported facts point to a different controlling condition: it requires the team to trend physical-layer counters and schedule corrective replacement. The alternative does not directly settle the required root-cause explanation.

Question 363

At the Highbridge energy utility, one network path has low throughput and rising frame check sequence errors while neighboring links are clean. What is the strongest acceptance test for this change?

  1. A known-good cable test removes CRC growth and restores expected throughput
  2. The negotiated link passes an error-free throughput validation
  3. The neighbor becomes established and authorized route advertisements are observed
  4. Measured optical levels return within specification and the link remains stable under load

Explanation

Correct Answer

A:

Because corrupt frames require retransmission even when link speed appears correctly negotiated, the required evidence must show that a known-good cable test removes CRC growth and restores expected throughput. A healthy endpoint status alone is insufficient. This result addresses the stated challenge at the Highbridge energy utility.

Incorrect Answers

B:

mismatched link parameters can create retransmissions and degraded forwarding even with link up, the required evidence must show that the negotiated link passes an error-free throughput validation. The offered alternative applies that mechanism: The negotiated link passes an error-free throughput validation. The reported facts point to a different controlling condition: corrupt frames require retransmission even when link speed appears correctly negotiated, the required evidence must show that a known-good cable test removes CRC growth and restores expected throughput. The alternative does not directly settle the required acceptance evidence.

C:

The neighbor becomes established and authorized route advertisements are observed. Its technical scope is explained by: it requires the team to monitor BGP transport and peer state after firewall updates. In this question, the decisive issue is: corrupt frames require retransmission even when link speed appears correctly negotiated, the required evidence must show that a known-good cable test removes CRC growth and restores expected throughput. That is why the offered option is not the most direct acceptance evidence.

D:

The option states: Measured optical levels return within specification and the link remains stable under load. The source describes its associated mechanism as: insufficient optical signal can cause link drops even with correct VLAN and routing setup. By contrast, the current situation is governed by: corrupt frames require retransmission even when link speed appears correctly negotiated, the required evidence must show that a known-good cable test removes CRC growth and restores expected throughput. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 364

At the Highbridge energy utility, one network path has low throughput and rising frame check sequence errors while neighboring links are clean. Which setting or practice should be reviewed in future?

  1. Review end-to-end QoS trust after new transit links
  2. Trend physical-layer counters and schedule corrective replacement
  3. Monitor PoE utilization and maintain reserve headroom
  4. Archive configurations and track diffs before every change

Explanation

Correct Answer

B:

This control works beyond the initial remediation because it requires the team to trend physical-layer counters and schedule corrective replacement. This result addresses the stated challenge at the Highbridge energy utility.

Incorrect Answers

A:

Review end-to-end QoS trust after new transit links. The reported problem is governed by this different mechanism: it requires the team to trend physical-layer counters and schedule corrective replacement. The offered choice would not address that particular recurrence control directly.

C:

The option states: Monitor PoE utilization and maintain reserve headroom. The source describes its associated mechanism as: exhausted shared PoE power can remove power from otherwise healthy endpoints; a passing acceptance check would show that all approved powered devices remain online at their peak expected draw. By contrast, the current situation is governed by: it requires the team to trend physical-layer counters and schedule corrective replacement. Choosing this alternative would leave the question’s specific recurrence control unresolved.

D:

Archive configurations and track diffs before every change. This option is based on the following distinct technical behavior: untracked changes make a fleet-wide regression difficult to diagnose and reverse safely. The present question instead depends on this mechanism: it requires the team to trend physical-layer counters and schedule corrective replacement. That difference matters for the requested recurrence control.

Question 365

At the Brookfield enterprise office, only one laptop model experiences poor wired performance after a driver update while switch counters remain healthy. Which corrective action best meets the requirement?

  1. Inspect physical error counters and validate cable optic and port conditions on the suspect hop
  2. Compare affected endpoint driver version and link behavior against a known-good device
  3. Identify inconsistent MST region mappings and align supported region parameters to the topology plan
  4. Use measured light levels and a known-good optic or fiber segment to isolate the physical fault

Explanation

Correct Answer

B:

The primary failure mode is that an endpoint driver defect can cause retries or negotiation issues without a switch fault. The proposed action directly fixes it by requiring the team to compare affected endpoint driver version and link behavior against a known-good device; afterward, verify that the controlled driver fix restores throughput only on affected devices. This result addresses the stated challenge at the Brookfield enterprise office.

Incorrect Answers

A:

Inspect physical error counters and validate cable optic and port conditions on the suspect hop. Its technical scope is explained by: corrupt frames require retransmission even when link speed appears correctly negotiated. In this question, the decisive issue is: an endpoint driver defect can cause retries or negotiation issues without a switch fault. That is why the offered option is not the most direct implementation.

C:

Identify inconsistent MST region mappings and align supported region parameters to the topology plan. The reported problem is governed by this different mechanism: an endpoint driver defect can cause retries or negotiation issues without a switch fault. The offered choice would not address that particular implementation directly.

D:

configuration changes cannot repair excessive attenuation or a defective transceiver; a passing acceptance check would show that after component replacement the same load test shows stable link and clean error counters. The offered alternative applies that mechanism: Use measured light levels and a known-good optic or fiber segment to isolate the physical fault. The reported facts point to a different controlling condition: an endpoint driver defect can cause retries or negotiation issues without a switch fault. The alternative does not directly settle the required implementation.

Question 366

At the Brookfield enterprise office, only one laptop model experiences poor wired performance after a driver update while switch counters remain healthy. Which underlying issue most directly explains this situation?

  1. A stateful security device may reject return flows when paths are asymmetric
  2. Exhausted shared PoE power can remove power from otherwise healthy endpoints
  3. Insufficient optical signal can cause link drops even with correct VLAN and routing setup
  4. An endpoint driver defect can cause retries or negotiation issues without a switch fault

Explanation

Correct Answer

D:

The problem stems from the fact that an endpoint driver defect can cause retries or negotiation issues without a switch fault. A correct solution would compare affected endpoint driver version and link behavior against a known-good device and check that the controlled driver fix restores throughput only on affected devices. This result addresses the stated challenge at the Brookfield enterprise office.

Incorrect Answers

A:

The option states: A stateful security device may reject return flows when paths are asymmetric. By contrast, the current situation is governed by: an endpoint driver defect can cause retries or negotiation issues without a switch fault. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

B:

Exhausted shared PoE power can remove power from otherwise healthy endpoints. This option is based on the following distinct technical behavior: exhausted shared PoE power can remove power from otherwise healthy endpoints; a passing acceptance check would show that all approved powered devices remain online at their peak expected draw. The present question instead depends on this mechanism: an endpoint driver defect can cause retries or negotiation issues without a switch fault. That difference matters for the requested root-cause explanation.

C:

The offered alternative states: Insufficient optical signal can cause link drops even with correct VLAN and routing setup. The reported facts point to a different controlling condition: an endpoint driver defect can cause retries or negotiation issues without a switch fault. The alternative does not directly settle the required root-cause explanation.

Question 367

At the Brookfield enterprise office, only one laptop model experiences poor wired performance after a driver update while switch counters remain healthy. What evidence would justify considering this concern addressed?

  1. A loaded traffic mix meets latency and loss targets for both protected classes
  2. The targeted queue correction restores application throughput while voice priority remains healthy
  3. Both peers reach the expected stable state and install the intended routes
  4. The controlled driver fix restores throughput only on affected devices

Explanation

Correct Answer

D:

This is the relevant acceptance result: the controlled driver fix restores throughput only on affected devices. It demonstrates the outcome of choosing to compare affected endpoint driver version and link behavior against a known-good device. This result addresses the stated challenge at the Brookfield enterprise office.

Incorrect Answers

A:

A loaded traffic mix meets latency and loss targets for both protected classes. This option is based on the following distinct technical behavior: an overly aggressive queue allocation can starve another important traffic class, rather than merely a monitoring or presentation issue. The present question instead depends on this mechanism: an endpoint driver defect can cause retries or negotiation issues without a switch fault. That difference matters for the requested acceptance evidence.

B:

it requires the team to use load tests and class counters as gates for QoS changes. The offered alternative applies that mechanism: The targeted queue correction restores application throughput while voice priority remains healthy. The reported facts point to a different controlling condition: an endpoint driver defect can cause retries or negotiation issues without a switch fault. The alternative does not directly settle the required acceptance evidence.

C:

Both peers reach the expected stable state and install the intended routes. Its technical scope is explained by: OSPF neighbors may reject or stall adjacency when interface parameters differ. In this question, the decisive issue is: an endpoint driver defect can cause retries or negotiation issues without a switch fault. That is why the offered option is not the most direct acceptance evidence.

Question 368

At the Brookfield enterprise office, only one laptop model experiences poor wired performance after a driver update while switch counters remain healthy. How should the organization sustain the improvement?

  1. Revalidate queue weights whenever workload patterns change
  2. Review optic health and loss budgets during fiber maintenance
  3. Track endpoint NIC and driver compatibility after image updates
  4. Record firmware validation and upgrade exceptions before wider rollout

Explanation

Correct Answer

C:

The continuing safeguard is to track endpoint NIC and driver compatibility after image updates. It helps avoid the original condition: an endpoint driver defect can cause retries or negotiation issues without a switch fault. This result addresses the stated challenge at the Brookfield enterprise office.

Incorrect Answers

A:

an overly aggressive queue allocation can starve another important traffic class, rather than merely a monitoring or presentation issue. The offered alternative applies that mechanism: Revalidate queue weights whenever workload patterns change. The reported facts point to a different controlling condition: an endpoint driver defect can cause retries or negotiation issues without a switch fault. The alternative does not directly settle the required recurrence control.

B:

Review optic health and loss budgets during fiber maintenance. Its technical scope is explained by: insufficient optical signal can cause link drops even with correct VLAN and routing setup. In this question, the decisive issue is: an endpoint driver defect can cause retries or negotiation issues without a switch fault. That is why the offered option is not the most direct recurrence control.

D:

Record firmware validation and upgrade exceptions before wider rollout. This option is based on the following distinct technical behavior: an untested fleet-wide image change can replace one defect with a broader outage, the required evidence must show that a pilot upgrade survives service tests and demonstrates a controlled fallback. The present question instead depends on this mechanism: an endpoint driver defect can cause retries or negotiation issues without a switch fault. That difference matters for the requested recurrence control.

Question 369

At the Jasperfield airport network, large application sessions break after a new default route sends return packets through a different security path. Which approach best resolves the described issue?

  1. Review traffic class assignments schedulers and per-queue occupancy against agreed service priorities
  2. Check VLAN presence and tagged membership along every hop of the wired trunk
  3. Trace DHCP discovery relay server reachability and scope availability to identify the failed component
  4. Trace both directions and align routing or firewall session policies with the approved topology

Explanation

Correct Answer

D:

Trace both directions and align routing or firewall session policies with the approved topology is the best response because a stateful security device may reject return flows when paths are asymmetric. A focused validation would establish that a bidirectional trace and test session confirm permitted symmetric or supported paths. This result addresses the stated challenge at the Jasperfield airport network.

Incorrect Answers

A:

Review traffic class assignments schedulers and per-queue occupancy against agreed service priorities. Its technical scope is explained by: an overly aggressive queue allocation can starve another important traffic class, rather than merely a monitoring or presentation issue. In this question, the decisive issue is: a stateful security device may reject return flows when paths are asymmetric. That is why the offered option is not the most direct root-cause explanation.

B:

The option states: Check VLAN presence and tagged membership along every hop of the wired trunk. The source describes its associated mechanism as: a physical link can be up while the VLAN tag is omitted or filtered. By contrast, the current situation is governed by: a stateful security device may reject return flows when paths are asymmetric. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

C:

Trace DHCP discovery relay server reachability and scope availability to identify the failed component. This option is based on the following distinct technical behavior: a Layer 3 path can pass static traffic while DHCP assignment fails separately. The present question instead depends on this mechanism: a stateful security device may reject return flows when paths are asymmetric. That difference matters for the requested root-cause explanation.

Question 370

At the Jasperfield airport network, large application sessions break after a new default route sends return packets through a different security path. Which explanation best accounts for the concern?

  1. Temperature sensitive optical hardware can fall outside receive tolerance and interrupt the link
  2. A stateful security device may reject return flows when paths are asymmetric
  3. Broad speculative configuration changes can expand an outage and obscure the original fault
  4. A poorly scoped route import can undermine segmentation without changing physical VLANs

Explanation

Correct Answer

B:

The problem stems from the fact that a stateful security device may reject return flows when paths are asymmetric. A correct solution would trace both directions and align routing or firewall session policies with the approved topology and check that a bidirectional trace and test session confirm permitted symmetric or supported paths. This result addresses the stated challenge at the Jasperfield airport network.
