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.

Question 81

At the Maplehaven transport facility, a video distribution design floods each campus segment because it omits IGMP and routing boundary decisions. Which approach best resolves the described issue?

  1. Plan supported IGMP snooping querier and multicast routed distribution for actual receiver groups
  2. Include addressing time synchronization and required Central reachability in the deployment checklist
  3. Evaluate a supported CX 8325 class fabric switch with appropriate speed and redundancy
  4. Evaluate a supported CX 6200 access design against PoE endpoint and uplink requirements

Explanation

Correct Answer

A:

The reported facts support this change rather than a general platform replacement. The team should plan supported IGMP snooping querier and multicast routed distribution for actual receiver groups because multicast delivery and control depend on membership learning and appropriate Layer 3 design. A suitable test confirms that a subscribed receiver sees the stream while nonmembers avoid unnecessary traffic. This result addresses the stated challenge at the Maplehaven transport facility.

Incorrect Answers

B:

The option states: Include addressing time synchronization and required Central reachability in the deployment checklist. The source describes its associated mechanism as: cloud management discovery and authentication can fail without basic underlay services; a passing acceptance check would show that the remote device joins the intended site and reports a current management connection. By contrast, the current situation is governed by: multicast delivery and control depend on membership learning and appropriate Layer 3 design. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

C:

Evaluate a supported CX 8325 class fabric switch with appropriate speed and redundancy. 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. The present question instead depends on this mechanism: multicast delivery and control depend on membership learning and appropriate Layer 3 design. That difference matters for the requested root-cause explanation.

D:

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: Evaluate a supported CX 6200 access design against PoE endpoint and uplink requirements. The reported facts point to a different controlling condition: multicast delivery and control depend on membership learning and appropriate Layer 3 design. The alternative does not directly settle the required root-cause explanation.

Question 82

At the Maplehaven transport facility, a video distribution design floods each campus segment because it omits IGMP and routing boundary decisions. Which explanation best accounts for the concern?

  1. Inconsistent VLAN and network addressing produces reachability and isolation faults during deployment
  2. Multicast delivery and control depend on membership learning and appropriate Layer 3 design
  3. Undersized aggregation links can oversubscribe building traffic and weaken resiliency
  4. Unsupported or mismatched optics can prevent link establishment despite matching connector shapes

Explanation

Correct Answer

B:

The problem stems from the fact that multicast delivery and control depend on membership learning and appropriate Layer 3 design. A correct solution would plan supported IGMP snooping querier and multicast routed distribution for actual receiver groups and check that a subscribed receiver sees the stream while nonmembers avoid unnecessary traffic. This result addresses the stated challenge at the Maplehaven transport facility.

Incorrect Answers

A:

The option states: Inconsistent VLAN and network addressing produces reachability and isolation faults during deployment. By contrast, the current situation is governed by: multicast delivery and control depend on membership learning and appropriate Layer 3 design. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

C:

The offered alternative states: Undersized aggregation links can oversubscribe building traffic and weaken resiliency. The reported facts point to a different controlling condition: multicast delivery and control depend on membership learning and appropriate Layer 3 design. The alternative does not directly settle the required root-cause explanation.

D:

Unsupported or mismatched optics can prevent link establishment despite matching connector shapes. In this question, the decisive issue is: multicast delivery and control depend on membership learning and appropriate Layer 3 design. That is why the offered option is not the most direct root-cause explanation.

Question 83

At the Maplehaven transport facility, a video distribution design floods each campus segment because it omits IGMP and routing boundary decisions. Which test result best shows the requirement is met?

  1. A test contractor reaches approved DNS and internet while sensitive server access fails
  2. A subscribed receiver sees the stream while nonmembers avoid unnecessary traffic
  3. The measured optical link stays up within vendor-supported reach and error targets
  4. A representative forwarding and failure test meets the documented data center service profile

Explanation

Correct Answer

B:

This is the relevant acceptance result: a subscribed receiver sees the stream while nonmembers avoid unnecessary traffic. It demonstrates the outcome of choosing to plan supported IGMP snooping querier and multicast routed distribution for actual receiver groups. This result addresses the stated challenge at the Maplehaven transport facility.

Incorrect Answers

A:

A test contractor reaches approved DNS and internet while sensitive server access fails. This option is based on the following distinct technical behavior: VLAN separation alone does not establish which inter-segment flows are permitted. The present question instead depends on this mechanism: multicast delivery and control depend on membership learning and appropriate Layer 3 design. That difference matters for the requested acceptance evidence.

C:

The measured optical link stays up within vendor-supported reach and error targets. Its technical scope is explained by: unsupported or mismatched optics can prevent link establishment despite matching connector shapes. In this question, the decisive issue is: multicast delivery and control depend on membership learning and appropriate Layer 3 design. That is why the offered option is not the most direct acceptance evidence.

D:

The option states: A representative forwarding and failure test meets the documented data center service profile. The source describes its associated mechanism as: access device selection does not establish the capacity and latency suitability of aggregation links. By contrast, the current situation is governed by: multicast delivery and control depend on membership learning and appropriate Layer 3 design. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 84

At the Maplehaven transport facility, a video distribution design floods each campus segment because it omits IGMP and routing boundary decisions. Which ongoing control best prevents this issue from recurring?

  1. Review segmentation exceptions and policy owners after contract changes
  2. Review group memberships and multicast capacity as video services expand
  3. Validate leaf oversubscription and replacement stock during quarterly capacity planning
  4. Review switch family selection when endpoint counts and services change

Explanation

Correct Answer

B:

The needed prevention is to review group memberships and multicast capacity as video services expand. It directly sustains the original change to plan supported IGMP snooping querier and multicast routed distribution for actual receiver groups. This result addresses the stated challenge at the Maplehaven transport facility.

Incorrect Answers

A:

VLAN separation alone does not establish which inter-segment flows are permitted. The offered alternative applies that mechanism: Review segmentation exceptions and policy owners after contract changes. The reported facts point to a different controlling condition: multicast delivery and control depend on membership learning and appropriate Layer 3 design. The alternative does not directly settle the required recurrence control.

C:

The option states: Validate leaf oversubscription and replacement stock during quarterly capacity planning. The source describes its associated mechanism as: data center leaf workloads demand interfaces and resilient forwarding not supplied by every access product, rather than merely a monitoring or presentation issue. By contrast, the current situation is governed by: multicast delivery and control depend on membership learning and appropriate Layer 3 design. Choosing this alternative would leave the question’s specific recurrence control unresolved.

D:

Review switch family selection when endpoint counts and services change. This option is based on the following distinct technical behavior: access closets and campus cores have different interface power redundancy and operational requirements. The present question instead depends on this mechanism: multicast delivery and control depend on membership learning and appropriate Layer 3 design. That difference matters for the requested recurrence control.

Question 85

At the Ashbourne retail infrastructure, a voice modernization specifies premium quality but includes no DSCP trust or queue policy across the switched path. Which implementation choice best addresses the situation?

  1. Plan supported IGMP snooping querier and multicast routed distribution for actual receiver groups
  2. Confirm Central supported device capabilities management licensing and operational scope before purchase
  3. Define end-to-end classification marking trust and queue behavior for voice and business traffic
  4. Validate approved optics reach fiber type port compatibility and link budget before procurement

Explanation

Correct Answer

C:

This is the direct HPE Aruba wired switching remedy: define end-to-end classification marking trust and queue behavior for voice and business traffic. The observed risk is that one access-port priority setting cannot protect traffic across every congested hop; a passing acceptance check would show that a loaded-path test meets voice loss and latency targets without starving other classes. This result addresses the stated challenge at the Ashbourne retail infrastructure.

Incorrect Answers

A:

Plan supported IGMP snooping querier and multicast routed distribution for actual receiver groups. Its technical scope is explained by: multicast delivery and control depend on membership learning and appropriate Layer 3 design. In this question, the decisive issue is: one access-port priority setting cannot protect traffic across every congested hop; a passing acceptance check would show that a loaded-path test meets voice loss and latency targets without starving other classes. That is why the offered option is not the most direct implementation.

B:

The option states: Confirm Central supported device capabilities management licensing and operational scope before purchase. 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: one access-port priority setting cannot protect traffic across every congested hop; a passing acceptance check would show that a loaded-path test meets voice loss and latency targets without starving other classes. Choosing this alternative would leave the question’s specific implementation unresolved.

D:

unsupported or mismatched optics can prevent link establishment despite matching connector shapes. The offered alternative applies that mechanism: Validate approved optics reach fiber type port compatibility and link budget before procurement. The reported facts point to a different controlling condition: one access-port priority setting cannot protect traffic across every congested hop; a passing acceptance check would show that a loaded-path test meets voice loss and latency targets without starving other classes. The alternative does not directly settle the required implementation.

Question 86

At the Ashbourne retail infrastructure, a voice modernization specifies premium quality but includes no DSCP trust or queue policy across the switched path. What risk should the team identify as the primary issue?

  1. One access-port priority setting cannot protect traffic across every congested hop
  2. An all-at-once cutover can leave essential services down without a recoverable configuration
  3. Core undersizing can create campus-wide congestion and costly replatforming
  4. Data center leaf workloads demand interfaces and resilient forwarding not supplied by every access product

Explanation

Correct Answer

A:

The situation shows that one access-port priority setting cannot protect traffic across every congested hop, rather than merely a monitoring or presentation issue. Remediation is to define end-to-end classification marking trust and queue behavior for voice and business traffic. This result addresses the stated challenge at the Ashbourne retail infrastructure.

Incorrect Answers

B:

An all-at-once cutover can leave essential services down without a recoverable configuration. The reported problem is governed by this different mechanism: one access-port priority setting cannot protect traffic across every congested hop, rather than merely a monitoring or presentation issue. The offered choice would not address that particular root-cause explanation directly.

C:

The offered alternative states: Core undersizing can create campus-wide congestion and costly replatforming. The reported facts point to a different controlling condition: one access-port priority setting cannot protect traffic across every congested hop, rather than merely a monitoring or presentation issue. The alternative does not directly settle the required root-cause explanation.

D:

Data center leaf workloads demand interfaces and resilient forwarding not supplied by every access product. Its technical scope is explained by: data center leaf workloads demand interfaces and resilient forwarding not supplied by every access product, rather than merely a monitoring or presentation issue. In this question, the decisive issue is: one access-port priority setting cannot protect traffic across every congested hop, rather than merely a monitoring or presentation issue. That is why the offered option is not the most direct root-cause explanation.

Question 87

At the Ashbourne retail infrastructure, a voice modernization specifies premium quality but includes no DSCP trust or queue policy across the switched path. What is the strongest acceptance test for this change?

  1. A supported test stack forms with the requested members and expected recovery
  2. A representative forwarding and failure test meets the documented data center service profile
  3. A loaded-path test meets voice loss and latency targets without starving other classes
  4. The selected switches onboard with the approved management subscription and policies

Explanation

Correct Answer

C:

This tests the real business behavior: a loaded-path test meets voice loss and latency targets without starving other classes. It specifically checks whether the risk that one access-port priority setting cannot protect traffic across every congested hop has been reduced. This result addresses the stated challenge at the Ashbourne retail infrastructure.

Incorrect Answers

A:

A supported test stack forms with the requested members and expected recovery. This option is based on the following distinct technical behavior: VSF interoperability and topology limits depend on the chosen hardware and software. The present question instead depends on this mechanism: one access-port priority setting cannot protect traffic across every congested hop, rather than merely a monitoring or presentation issue. That difference matters for the requested acceptance evidence.

B:

access device selection does not establish the capacity and latency suitability of aggregation links. The offered alternative applies that mechanism: A representative forwarding and failure test meets the documented data center service profile. The reported facts point to a different controlling condition: one access-port priority setting cannot protect traffic across every congested hop, rather than merely a monitoring or presentation issue. 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: one access-port priority setting cannot protect traffic across every congested hop, rather than merely a monitoring or presentation issue. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 88

At the Ashbourne retail infrastructure, a voice modernization specifies premium quality but includes no DSCP trust or queue policy across the switched path. Which setting or practice should be reviewed in future?

  1. Monitor onboarding prerequisites whenever branch ISP paths change
  2. Track management license status and model support changes
  3. Review QoS policy and traffic class mappings after application changes
  4. Review switch family selection when endpoint counts and services change

Explanation

Correct Answer

C:

The team should review QoS policy and traffic class mappings after application changes. That recurring practice targets the same weakness, namely that one access-port priority setting cannot protect traffic across every congested hop. This result addresses the stated challenge at the Ashbourne retail infrastructure.

Incorrect Answers

A:

cloud management discovery and authentication can fail without basic underlay services. The offered alternative applies that mechanism: Monitor onboarding prerequisites whenever branch ISP paths change. The reported facts point to a different controlling condition: one access-port priority setting cannot protect traffic across every congested hop, rather than merely a monitoring or presentation issue. The alternative does not directly settle the required recurrence control.

B:

Track management license status and model support changes. Its technical scope is explained by: central management eligibility depends on product software and contracted entitlements rather than cabling alone. In this question, the decisive issue is: one access-port priority setting cannot protect traffic across every congested hop, rather than merely a monitoring or presentation issue. That is why the offered option is not the most direct recurrence control.

D:

Review switch family selection when endpoint counts and services change. This option is based on the following distinct technical behavior: access closets and campus cores have different interface power redundancy and operational requirements. The present question instead depends on this mechanism: one access-port priority setting cannot protect traffic across every congested hop, rather than merely a monitoring or presentation issue. That difference matters for the requested recurrence control.

Question 89

At the Quayside energy utility, a company introduces contractor VLANs without documenting approved access to shared services. Which corrective action best meets the requirement?

  1. Create a governed VLAN-to-subnet mapping with routing and migration dependencies
  2. Evaluate a supported CX 6200 access design against PoE endpoint and uplink requirements
  3. Define a security policy matrix and staged segment access validation before deployment
  4. Compare the supported CX 8100 data center aggregation role against port speed and fabric needs

Explanation

Correct Answer

C:

The reported facts support this change rather than a general platform replacement. The team should define a security policy matrix and staged segment access validation before deployment because VLAN separation alone does not establish which inter-segment flows are permitted. A suitable test confirms that a test contractor reaches approved DNS and internet while sensitive server access fails. This result addresses the stated challenge at the Quayside energy utility.

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: VLAN separation alone does not establish which inter-segment flows are permitted. That is why the offered option is not the most direct implementation.

B:

The option states: Evaluate a supported CX 6200 access design against PoE endpoint and uplink requirements. The source describes its associated mechanism as: 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. By contrast, the current situation is governed by: VLAN separation alone does not establish which inter-segment flows are permitted. Choosing this alternative would leave the question’s specific implementation unresolved.

D:

access device selection does not establish the capacity and latency suitability of aggregation links. The offered alternative applies that mechanism: Compare the supported CX 8100 data center aggregation role against port speed and fabric needs. The reported facts point to a different controlling condition: VLAN separation alone does not establish which inter-segment flows are permitted. The alternative does not directly settle the required implementation.

Question 90

At the Quayside energy utility, a company introduces contractor VLANs without documenting approved access to shared services. Which underlying issue most directly explains this situation?

  1. Inconsistent VLAN and network addressing produces reachability and isolation faults during deployment
  2. VLAN separation alone does not establish which inter-segment flows are permitted
  3. Different operating system families do not guarantee equivalent command syntax or feature behavior
  4. Core undersizing can create campus-wide congestion and costly replatforming

Explanation

Correct Answer

B:

The architectural weakness is that VLAN separation alone does not establish which inter-segment flows are permitted. It can be addressed through the controlled change to define a security policy matrix and staged segment access validation before deployment. This result addresses the stated challenge at the Quayside energy utility.

Incorrect Answers

A:

The option states: Inconsistent VLAN and network addressing produces reachability and isolation faults during deployment. By contrast, the current situation is governed by: VLAN separation alone does not establish which inter-segment flows are permitted. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

C:

The offered alternative states: Different operating system families do not guarantee equivalent command syntax or feature behavior. The reported facts point to a different controlling condition: VLAN separation alone does not establish which inter-segment flows are permitted. The alternative does not directly settle the required root-cause explanation.

D:
