Question 70

At the Yorkport airport network, a renovated campus will power 48 cameras and phones from a switch whose PoE budget has not been calculated. Which explanation best accounts for the concern?

  1. A port count alone does not guarantee simultaneous available PoE watts
  2. Multicast delivery and control depend on membership learning and appropriate Layer 3 design
  3. Data center leaf workloads demand interfaces and resilient forwarding not supplied by every access product
  4. Core undersizing can create campus-wide congestion and costly replatforming

Explanation

Correct Answer

A:

The strongest explanation is that a port count alone does not guarantee simultaneous available PoE watts. This accounts for the outcome and supports the action to budget per port PoE requirements and total switch power with reserve for critical endpoints. This result addresses the stated challenge at the Yorkport airport network.

Incorrect Answers

B:

Multicast delivery and control depend on membership learning and appropriate Layer 3 design. The present question instead depends on this mechanism: it requires the team to recalculate PoE headroom when cameras or phones are upgraded. That difference matters for the requested root-cause explanation.

C:

data center leaf workloads demand interfaces and resilient forwarding not supplied by every access product, rather than merely a monitoring or presentation issue. The offered alternative applies that mechanism: Data center leaf workloads demand interfaces and resilient forwarding not supplied by every access product. The reported facts point to a different controlling condition: it requires the team to recalculate PoE headroom when cameras or phones are upgraded. The alternative does not directly settle the required root-cause explanation.

D:

Core undersizing can create campus-wide congestion and costly replatforming. In this question, the decisive issue is: it requires the team to recalculate PoE headroom when cameras or phones are upgraded. That is why the offered option is not the most direct root-cause explanation.

Question 71

At the Yorkport airport network, a renovated campus will power 48 cameras and phones from a switch whose PoE budget has not been calculated. Which test result best shows the requirement is met?

  1. The validated pair reports healthy peer state and passes a member isolation test
  2. A device and power budget confirms all branch phones and workstations operate within capacity
  3. All test endpoints operate at peak expected power without denial or overload
  4. The selected switches onboard with the approved management subscription and policies

Explanation

Correct Answer

C:

Because a port count alone does not guarantee simultaneous available PoE watts, the required evidence must show that all test endpoints operate at peak expected power without denial or overload. A healthy endpoint status alone is insufficient. This result addresses the stated challenge at the Yorkport airport network.

Incorrect Answers

A:

The validated pair reports healthy peer state and passes a member isolation test. The reported problem is governed by this different mechanism: a port count alone does not guarantee simultaneous available PoE watts, the required evidence must show that all test endpoints operate at peak expected power without denial or overload. The offered choice would not address that particular acceptance evidence directly.

B:

purchase price alone omits required power budgets uplink speeds and management capabilities; a passing acceptance check would show that a device and power budget confirms all branch phones and workstations operate within capacity. The offered alternative applies that mechanism: A device and power budget confirms all branch phones and workstations operate within capacity. The reported facts point to a different controlling condition: a port count alone does not guarantee simultaneous available PoE watts, the required evidence must show that all test endpoints operate at peak expected power without denial or overload. The alternative does not directly settle the required acceptance evidence.

D:

The option states: The selected switches onboard with the approved management subscription and policies. The source describes its associated mechanism as: central management eligibility depends on product software and contracted entitlements rather than cabling alone. By contrast, the current situation is governed by: a port count alone does not guarantee simultaneous available PoE watts, the required evidence must show that all test endpoints operate at peak expected power without denial or overload. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 72

At the Yorkport airport network, a renovated campus will power 48 cameras and phones from a switch whose PoE budget has not been calculated. Which ongoing control best prevents this issue from recurring?

  1. Review subnet capacity and assignment when new buildings are added
  2. Review aggregation capacity and platform compatibility as the fabric changes
  3. Audit optic inventory and firmware compatibility before building moves
  4. Recalculate PoE headroom when cameras or phones are upgraded

Explanation

Correct Answer

D:

This control works beyond the initial remediation because it requires the team to recalculate PoE headroom when cameras or phones are upgraded. This result addresses the stated challenge at the Yorkport airport network.

Incorrect Answers

A:

inconsistent VLAN and network addressing produces reachability and isolation faults during deployment. The offered alternative applies that mechanism: Review subnet capacity and assignment when new buildings are added. The reported facts point to a different controlling condition: it requires the team to recalculate PoE headroom when cameras or phones are upgraded. The alternative does not directly settle the required recurrence control.

B:

Review aggregation capacity and platform compatibility as the fabric changes. Its technical scope is explained by: access device selection does not establish the capacity and latency suitability of aggregation links. In this question, the decisive issue is: it requires the team to recalculate PoE headroom when cameras or phones are upgraded. That is why the offered option is not the most direct recurrence control.

C:

The option states: Audit optic inventory and firmware compatibility before building moves. The source describes its associated mechanism as: unsupported or mismatched optics can prevent link establishment despite matching connector shapes. By contrast, the current situation is governed by: it requires the team to recalculate PoE headroom when cameras or phones are upgraded. Choosing this alternative would leave the question’s specific recurrence control unresolved.

Question 73

At the Nortonwood financial services network, a distribution design assumes two parallel Ethernet links automatically combine without matching LACP configuration. Which implementation choice best addresses the situation?

  1. Create a governed VLAN-to-subnet mapping with routing and migration dependencies
  2. Evaluate a supported CX 8325 class fabric switch with appropriate speed and redundancy
  3. Validate approved optics reach fiber type port compatibility and link budget before procurement
  4. Specify the link aggregation groups member interfaces negotiation and peer configuration on both ends

Explanation

Correct Answer

D:

The primary failure mode is that uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. The proposed action directly fixes it by requiring the team to specify the link aggregation groups member interfaces negotiation and peer configuration on both ends; afterward, verify that the test LAG forwards and maintains service after one member is removed. This result addresses the stated challenge at the Nortonwood financial services network.

Incorrect Answers

A:

Create a governed VLAN-to-subnet mapping with routing and migration dependencies. Its technical scope is explained by: inconsistent VLAN and network addressing produces reachability and isolation faults during deployment. In this question, the decisive issue is: uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. That is why the offered option is not the most direct implementation.

B:

The option states: Evaluate a supported CX 8325 class fabric switch with appropriate speed and redundancy. The source describes its associated mechanism as: data center leaf workloads demand interfaces and resilient forwarding not supplied by every access product. By contrast, the current situation is governed by: uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. Choosing this alternative would leave the question’s specific implementation unresolved.

C:

Validate approved optics reach fiber type port compatibility and link budget before procurement. This option is based on the following distinct technical behavior: unsupported or mismatched optics can prevent link establishment despite matching connector shapes. The present question instead depends on this mechanism: uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. That difference matters for the requested implementation.

Question 74

At the Nortonwood financial services network, a distribution design assumes two parallel Ethernet links automatically combine without matching LACP configuration. What risk should the team identify as the primary issue?

  1. An all-at-once cutover can leave essential services down without a recoverable configuration
  2. A fixed platform cannot always provide the requested chassis scale or modular resilience
  3. Undersized aggregation links can oversubscribe building traffic and weaken resiliency
  4. Uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate

Explanation

Correct Answer

D:

The architectural weakness is that uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. It can be addressed through the controlled change to specify the link aggregation groups member interfaces negotiation and peer configuration on both ends. This result addresses the stated challenge at the Nortonwood financial services network.

Incorrect Answers

A:

An all-at-once cutover can leave essential services down without a recoverable configuration. The reported problem is governed by this different mechanism: uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. The offered choice would not address that particular root-cause explanation directly.

B:

A fixed platform cannot always provide the requested chassis scale or modular resilience. This option is based on the following distinct technical behavior: a fixed platform cannot always provide the requested chassis scale or modular resilience, rather than merely a monitoring or presentation issue. The present question instead depends on this mechanism: uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. That difference matters for the requested root-cause explanation.

C:

The offered alternative states: Undersized aggregation links can oversubscribe building traffic and weaken resiliency. The reported facts point to a different controlling condition: uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. The alternative does not directly settle the required root-cause explanation.

Question 75

At the Nortonwood financial services network, a distribution design assumes two parallel Ethernet links automatically combine without matching LACP configuration. What is the strongest acceptance test for this change?

  1. A pilot closet converts and rolls back within the tested maintenance window
  2. The test LAG forwards and maintains service after one member is removed
  3. The bill of materials supports the required modules and simulated component loss
  4. The selected switches onboard with the approved management subscription and policies

Explanation

Correct Answer

B:

The team can confirm the fix by showing that the test LAG forwards and maintains service after one member is removed. This aligns with the corrective design to specify the link aggregation groups member interfaces negotiation and peer configuration on both ends. This result addresses the stated challenge at the Nortonwood financial services network.

Incorrect Answers

A:

A pilot closet converts and rolls back within the tested maintenance window. The reported problem is governed by this different mechanism: uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. The offered choice would not address that particular acceptance evidence directly.

C:

The bill of materials supports the required modules and simulated component loss. Its technical scope is explained by: it requires the team to review chassis headroom and redundant component inventories before major expansions. In this question, the decisive issue is: uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. That is why the offered option is not the most direct acceptance evidence.

D:

The option states: The selected switches onboard with the approved management subscription and policies. The source describes its associated mechanism as: central management eligibility depends on product software and contracted entitlements rather than cabling alone. By contrast, the current situation is governed by: uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 76

At the Nortonwood financial services network, a distribution design assumes two parallel Ethernet links automatically combine without matching LACP configuration. Which setting or practice should be reviewed in future?

  1. Audit LACP group consistency during physical cabling changes
  2. Require cutover checklists and recovery evidence for each facility
  3. Track management license status and model support changes
  4. Validate leaf oversubscription and replacement stock during quarterly capacity planning

Explanation

Correct Answer

A:

After implementation, the team should audit LACP group consistency during physical cabling changes as the appropriate recurring safeguard against the identified issue. This result addresses the stated challenge at the Nortonwood financial services network.

Incorrect Answers

B:

Require cutover checklists and recovery evidence for each facility. The reported problem is governed by this different mechanism: uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. The offered choice would not address that particular recurrence control directly.

C:

The option states: Track management license status and model support changes. The source describes its associated mechanism as: central management eligibility depends on product software and contracted entitlements rather than cabling alone. By contrast, the current situation is governed by: uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. Choosing this alternative would leave the question’s specific recurrence control unresolved.

D:

Validate leaf oversubscription and replacement stock during quarterly capacity planning. This option is based on the following distinct technical behavior: data center leaf workloads demand interfaces and resilient forwarding not supplied by every access product, rather than merely a monitoring or presentation issue. The present question instead depends on this mechanism: uncoordinated parallel ports may create loops or remain individual links rather than a single aggregate. That difference matters for the requested recurrence control.

Question 77

At the Northport regional library system, a campus routing migration enables OSPF without documenting neighbor area and authentication requirements. Which corrective action best meets the requirement?

  1. Create a governed VLAN-to-subnet mapping with routing and migration dependencies
  2. Prepare a neighbor matrix covering OSPF areas IP interfaces timers and approved authentication
  3. Validate approved optics reach fiber type port compatibility and link budget before procurement
  4. Evaluate a supported CX 6200 access design against PoE endpoint and uplink requirements

Explanation

Correct Answer

B:

The primary failure mode is that OSPF peers require matching adjacency conditions before exchanging routes. The proposed action directly fixes it by requiring the team to prepare a neighbor matrix covering OSPF areas IP interfaces timers and approved authentication; afterward, verify that configured neighbors reach Full state and required destinations appear in the routing table. This result addresses the stated challenge at the Northport regional library system.

Incorrect Answers

A:

Create a governed VLAN-to-subnet mapping with routing and migration dependencies. Its technical scope is explained by: inconsistent VLAN and network addressing produces reachability and isolation faults during deployment.

Question 79

At the Northport regional library system, a campus routing migration enables OSPF without documenting neighbor area and authentication requirements. What evidence would justify considering this concern addressed?

  1. An address and VLAN validation matrix matches every intended endpoint segment
  2. A device and power budget confirms all branch phones and workstations operate within capacity
  3. The selected switches onboard with the approved management subscription and policies
  4. Configured neighbors reach Full state and required destinations appear in the routing table

Explanation

Correct Answer

D:

This is the relevant acceptance result: configured neighbors reach Full state and required destinations appear in the routing table. It demonstrates the outcome of choosing to prepare a neighbor matrix covering OSPF areas IP interfaces timers and approved authentication. This result addresses the stated challenge at the Northport regional library system.

Incorrect Answers

A:

An address and VLAN validation matrix matches every intended endpoint segment. This option is based on the following distinct technical behavior: inconsistent VLAN and network addressing produces reachability and isolation faults during deployment. The present question instead depends on this mechanism: OSPF peers require matching adjacency conditions before exchanging routes. That difference matters for the requested acceptance evidence.

B:

purchase price alone omits required power budgets uplink speeds and management capabilities; a passing acceptance check would show that a device and power budget confirms all branch phones and workstations operate within capacity.

Question 80

At the Northport regional library system, a campus routing migration enables OSPF without documenting neighbor area and authentication requirements. How should the organization sustain the improvement?

  1. Review group memberships and multicast capacity as video services expand
  2. Review chassis headroom and redundant component inventories before major expansions
  3. Validate OSPF neighbor and route baselines after each rollout phase
  4. Update core capacity forecasts and platform lifecycle plans annually

Explanation

Correct Answer

C:

The continuing safeguard is to validate OSPF neighbor and route baselines after each rollout phase. It helps avoid the original condition: OSPF peers require matching adjacency conditions before exchanging routes. This result addresses the stated challenge at the Northport regional library system.

Incorrect Answers

A:

multicast delivery and control depend on membership learning and appropriate Layer 3 design. The offered alternative applies that mechanism: Review group memberships and multicast capacity as video services expand. The reported facts point to a different controlling condition: OSPF peers require matching adjacency conditions before exchanging routes. The alternative does not directly settle the required recurrence control.

B:

Review chassis headroom and redundant component inventories before major expansions. Its technical scope is explained by: it requires the team to review chassis headroom and redundant component inventories before major expansions. In this question, the decisive issue is: OSPF peers require matching adjacency conditions before exchanging routes. That is why the offered option is not the most direct recurrence control.

D:

Update core capacity forecasts and platform lifecycle plans annually. This option is based on the following distinct technical behavior: core undersizing can create campus-wide congestion and costly replatforming. The present question instead depends on this mechanism: OSPF peers require matching adjacency conditions before exchanging routes. That difference matters for the requested recurrence control.
