Question 130

At the Uptonbridge school district, a distribution switch has two power modules connected to the same failed circuit. Which explanation best accounts for the concern?

  1. Mismatched optic characteristics prevent a valid light path despite correct switch configuration
  2. Two power supplies on one electrical source do not protect against a common circuit failure
  3. Without learned receiver groups a Layer 2 multicast stream may be flooded to unrelated ports
  4. BGP neighbors require compatible AS relationships and reachable transport before exchanging routes

Explanation

Correct Answer

B:

The problem stems from the fact that two power supplies on one electrical source do not protect against a common circuit failure. A correct solution would feed supported redundant power supplies from independent approved circuits and verify failover and check that removing one approved circuit leaves forwarding and required modules operational. This result addresses the stated challenge at the Uptonbridge school district.

Incorrect Answers

A:

The option states: Mismatched optic characteristics prevent a valid light path despite correct switch configuration. By contrast, the current situation is governed by: two power supplies on one electrical source do not protect against a common circuit failure. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

C:

without learned receiver groups a Layer 2 multicast stream may be flooded to unrelated ports, rather than merely a monitoring or presentation issue. The offered alternative applies that mechanism: Without learned receiver groups a Layer 2 multicast stream may be flooded to unrelated ports. The reported facts point to a different controlling condition: two power supplies on one electrical source do not protect against a common circuit failure. The alternative does not directly settle the required root-cause explanation.

D:

BGP neighbors require compatible AS relationships and reachable transport before exchanging routes. Its technical scope is explained by: BGP neighbors require compatible AS relationships and reachable transport before exchanging routes, rather than merely a monitoring or presentation issue. In this question, the decisive issue is: two power supplies on one electrical source do not protect against a common circuit failure. That is why the offered option is not the most direct root-cause explanation.

Question 131

At the Uptonbridge school district, a distribution switch has two power modules connected to the same failed circuit. Which test result best shows the requirement is met?

  1. Optical diagnostics show receive levels within specification and the link establishes
  2. Removing one approved circuit leaves forwarding and required modules operational
  3. Neighbor state reaches Full and expected link state routes are installed
  4. An authorized SSH login succeeds while an unauthorized plaintext management attempt fails

Explanation

Correct Answer

B:

This is the relevant acceptance result: removing one approved circuit leaves forwarding and required modules operational. It demonstrates the outcome of choosing to feed supported redundant power supplies from independent approved circuits and verify failover. This result addresses the stated challenge at the Uptonbridge school district.

Incorrect Answers

A:

Optical diagnostics show receive levels within specification and the link establishes. This option is based on the following distinct technical behavior: mismatched optic characteristics prevent a valid light path despite correct switch configuration. The present question instead depends on this mechanism: it requires the team to audit power source diversity and module status during site inspections. That difference matters for the requested acceptance evidence.

C:

Neighbor state reaches Full and expected link state routes are installed. Its technical scope is explained by: area or hello mismatch on adjacent interfaces prevents normal OSPF peering, the required evidence must show that neighbor state reaches Full and expected link state routes are installed. In this question, the decisive issue is: it requires the team to audit power source diversity and module status during site inspections. That is why the offered option is not the most direct acceptance evidence.

D:

The option states: An authorized SSH login succeeds while an unauthorized plaintext management attempt fails. The source describes its associated mechanism as: unencrypted or broadly reachable management exposes network configuration and credentials, the required evidence must show that an authorized SSH login succeeds while an unauthorized plaintext management attempt fails. By contrast, the current situation is governed by: it requires the team to audit power source diversity and module status during site inspections. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 132

At the Uptonbridge school district, a distribution switch has two power modules connected to the same failed circuit. Which ongoing control best prevents this issue from recurring?

  1. Keep approved optics and fiber testing records for each cable plant
  2. Audit access VLAN mappings after workstation moves
  3. Retest traffic markings after endpoint software updates
  4. Audit power source diversity and module status during site inspections

Explanation

Correct Answer

D:

This control works beyond the initial remediation because it requires the team to audit power source diversity and module status during site inspections. This result addresses the stated challenge at the Uptonbridge school district.

Incorrect Answers

A:

mismatched optic characteristics prevent a valid light path despite correct switch configuration. The offered alternative applies that mechanism: Keep approved optics and fiber testing records for each cable plant. The reported facts point to a different controlling condition: it requires the team to audit power source diversity and module status during site inspections. The alternative does not directly settle the required recurrence control.

B:

Audit access VLAN mappings after workstation moves. Its technical scope is explained by: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. In this question, the decisive issue is: it requires the team to audit power source diversity and module status during site inspections. That is why the offered option is not the most direct recurrence control.

C:

The option states: Retest traffic markings after endpoint software updates. The source describes its associated mechanism as: a configured policy may not match traffic or may be rewritten further along the path. By contrast, the current situation is governed by: it requires the team to audit power source diversity and module status during site inspections. Choosing this alternative would leave the question’s specific recurrence control unresolved.

Question 133

At the Juniperford media production office, a core port is configured for multiple downstream interfaces without compatible breakout cable and port mode. Which implementation choice best addresses the situation?

  1. Check available PoE budget per port classification cabling and total supply against measured demand
  2. Implement supported classification and queue scheduling for voice without starving other traffic classes
  3. Set the intended untagged access VLAN on the endpoint interface and verify its forwarding role
  4. Verify support for breakout on the exact model port speed transceiver and cable before configuring the logical interfaces

Explanation

Correct Answer

D:

The primary failure mode is that a physical breakout requires matched hardware and operating mode rather than only an interface name. The proposed action directly fixes it by requiring the team to verify support for breakout on the exact model port speed transceiver and cable before configuring the logical interfaces; afterward, verify that all intended breakout links negotiate supported speed and pass connectivity tests. This result addresses the stated challenge at the Juniperford media production office.

Incorrect Answers

A:

Check available PoE budget per port classification cabling and total supply against measured demand. Its technical scope is explained by: total chassis PoE consumption can exceed available power when endpoints start together. In this question, the decisive issue is: a physical breakout requires matched hardware and operating mode rather than only an interface name. That is why the offered option is not the most direct implementation.

B:

The option states: Implement supported classification and queue scheduling for voice without starving other traffic classes. The source describes its associated mechanism as: a single congested best-effort queue does not protect latency-sensitive voice packets. By contrast, the current situation is governed by: a physical breakout requires matched hardware and operating mode rather than only an interface name. Choosing this alternative would leave the question’s specific implementation unresolved.

C:

Set the intended untagged access VLAN on the endpoint interface and verify its forwarding role. This option is based on the following distinct technical behavior: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. The present question instead depends on this mechanism: a physical breakout requires matched hardware and operating mode rather than only an interface name. That difference matters for the requested implementation.

Question 134

At the Juniperford media production office, a core port is configured for multiple downstream interfaces without compatible breakout cable and port mode. What risk should the team identify as the primary issue?

  1. Mismatched optic characteristics prevent a valid light path despite correct switch configuration
  2. A physical breakout requires matched hardware and operating mode rather than only an interface name
  3. An incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain
  4. An established Ethernet link does not imply all tagged VLANs are carried across it

Explanation

Correct Answer

B:

This identifies the root issue: a physical breakout requires matched hardware and operating mode rather than only an interface name. At the Juniperford media production office, the team should therefore verify support for breakout on the exact model port speed transceiver and cable before configuring the logical interfaces.

Incorrect Answers

A:

The option states: Mismatched optic characteristics prevent a valid light path despite correct switch configuration. By contrast, the current situation is governed by: a physical breakout requires matched hardware and operating mode rather than only an interface name. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

C:

The offered alternative states: An incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. The reported facts point to a different controlling condition: a physical breakout requires matched hardware and operating mode rather than only an interface name. The alternative does not directly settle the required root-cause explanation.

D:

An established Ethernet link does not imply all tagged VLANs are carried across it. In this question, the decisive issue is: a physical breakout requires matched hardware and operating mode rather than only an interface name. That is why the offered option is not the most direct root-cause explanation.

Question 135

At the Juniperford media production office, a core port is configured for multiple downstream interfaces without compatible breakout cable and port mode. What is the strongest acceptance test for this change?

  1. All intended breakout links negotiate supported speed and pass connectivity tests
  2. All simulated high load PoE clients remain powered with margin
  3. A scheduled synchronization preserves the approved setting and records its source
  4. An authorized SSH login succeeds while an unauthorized plaintext management attempt fails

Explanation

Correct Answer

A:

Because a physical breakout requires matched hardware and operating mode rather than only an interface name, the required evidence must show that all intended breakout links negotiate supported speed and pass connectivity tests. A healthy endpoint status alone is insufficient. This result addresses the stated challenge at the Juniperford media production office.

Incorrect Answers

B:

total chassis PoE consumption can exceed available power when endpoints start together. The offered alternative applies that mechanism: All simulated high load PoE clients remain powered with margin. The reported facts point to a different controlling condition: a physical breakout requires matched hardware and operating mode rather than only an interface name, the required evidence must show that all intended breakout links negotiate supported speed and pass connectivity tests. The alternative does not directly settle the required acceptance evidence.

C:

A scheduled synchronization preserves the approved setting and records its source. Its technical scope is explained by: group managed configurations can supersede direct local changes when ownership is not coordinated. In this question, the decisive issue is: a physical breakout requires matched hardware and operating mode rather than only an interface name, the required evidence must show that all intended breakout links negotiate supported speed and pass connectivity tests. That is why the offered option is not the most direct acceptance evidence.

D:

The option states: An authorized SSH login succeeds while an unauthorized plaintext management attempt fails. The source describes its associated mechanism as: unencrypted or broadly reachable management exposes network configuration and credentials, the required evidence must show that an authorized SSH login succeeds while an unauthorized plaintext management attempt fails. By contrast, the current situation is governed by: a physical breakout requires matched hardware and operating mode rather than only an interface name, the required evidence must show that all intended breakout links negotiate supported speed and pass connectivity tests. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 136

At the Juniperford media production office, a core port is configured for multiple downstream interfaces without compatible breakout cable and port mode. Which setting or practice should be reviewed in future?

  1. Review power utilization and supply redundancy as endpoints grow
  2. Use context-aware configuration reviews and peer verification
  3. Revalidate breakout compatibility after interface module or optics replacement
  4. Monitor LACP actor partner status after port changes

Explanation

Correct Answer

C:

The team should revalidate breakout compatibility after interface module or optics replacement. That recurring practice targets the same weakness, namely that a physical breakout requires matched hardware and operating mode rather than only an interface name. This result addresses the stated challenge at the Juniperford media production office.

Incorrect Answers

A:

total chassis PoE consumption can exceed available power when endpoints start together. The offered alternative applies that mechanism: Review power utilization and supply redundancy as endpoints grow. The reported facts point to a different controlling condition: a physical breakout requires matched hardware and operating mode rather than only an interface name, the required evidence must show that all intended breakout links negotiate supported speed and pass connectivity tests. The alternative does not directly settle the required recurrence control.

B:

Use context-aware configuration reviews and peer verification. Its technical scope is explained by: a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. In this question, the decisive issue is: a physical breakout requires matched hardware and operating mode rather than only an interface name, the required evidence must show that all intended breakout links negotiate supported speed and pass connectivity tests. That is why the offered option is not the most direct recurrence control.

D:

Monitor LACP actor partner status after port changes. This option is based on the following distinct technical behavior: it requires the team to monitor LACP actor partner status after port changes. The present question instead depends on this mechanism: a physical breakout requires matched hardware and operating mode rather than only an interface name, the required evidence must show that all intended breakout links negotiate supported speed and pass connectivity tests. That difference matters for the requested recurrence control.

Question 137

At the Brookfield transport facility, a finance workstation receives the guest subnet after moving to a newly configured CX access port. Which corrective action best meets the requirement?

  1. Align approved native or untagged VLAN behavior on both ends and avoid unnecessary untagged service traffic
  2. Set the intended untagged access VLAN on the endpoint interface and verify its forwarding role
  3. Align OSPF area and adjacency parameters on the intended interfaces then validate neighbors
  4. Verify required Central control-plane DNS time and outbound management connectivity without exposing switch administration publicly

Explanation

Correct Answer

B:

The primary failure mode is that an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. The proposed action directly fixes it by requiring the team to set the intended untagged access VLAN on the endpoint interface and verify its forwarding role; afterward, verify that the test endpoint obtains the finance subnet while guest resources stay isolated. This result addresses the stated challenge at the Brookfield transport facility.

Incorrect Answers

A:

Align approved native or untagged VLAN behavior on both ends and avoid unnecessary untagged service traffic. Its technical scope is explained by: different untagged VLAN handling can leak or misdeliver management and user frames. In this question, the decisive issue is: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. That is why the offered option is not the most direct implementation.

C:

Align OSPF area and adjacency parameters on the intended interfaces then validate neighbors. This option is based on the following distinct technical behavior: area or hello mismatch on adjacent interfaces prevents normal OSPF peering. The present question instead depends on this mechanism: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. That difference matters for the requested implementation.

D:

local traffic forwarding can survive while cloud management communication is blocked. The offered alternative applies that mechanism: Verify required Central control-plane DNS time and outbound management connectivity without exposing switch administration publicly. The reported facts point to a different controlling condition: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. The alternative does not directly settle the required implementation.

Question 138

At the Brookfield transport facility, a finance workstation receives the guest subnet after moving to a newly configured CX access port. Which underlying issue most directly explains this situation?

  1. An incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain
  2. Incorrect VSF stacking links or member configuration can prevent a common logical control plane
  3. Incorrect VRF assignment defeats the intended separation of independent routing contexts
  4. Two power supplies on one electrical source do not protect against a common circuit failure

Explanation

Correct Answer

A:

The evidence indicates that an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. The appropriate response is to set the intended untagged access VLAN on the endpoint interface and verify its forwarding role and demonstrate that the test endpoint obtains the finance subnet while guest resources stay isolated. This result addresses the stated challenge at the Brookfield transport facility.

Incorrect Answers

B:

Incorrect VSF stacking links or member configuration can prevent a common logical control plane. The present question instead depends on this mechanism: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. That difference matters for the requested root-cause explanation.

C:

The offered alternative states: Incorrect VRF assignment defeats the intended separation of independent routing contexts. The reported facts point to a different controlling condition: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. The alternative does not directly settle the required root-cause explanation.

D:

Two power supplies on one electrical source do not protect against a common circuit failure. In this question, the decisive issue is: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. That is why the offered option is not the most direct root-cause explanation.

Question 139

At the Brookfield transport facility, a finance workstation receives the guest subnet after moving to a newly configured CX access port. What evidence would justify considering this concern addressed?

  1. The test endpoint obtains the finance subnet while guest resources stay isolated
  2. A tagged and untagged test confirms the intended VLAN separation across the link
  3. Sample devices show the approved firmware version after a phased compliant upgrade
  4. The device appears online in the correct site and reports the expected managed configuration

Explanation

Correct Answer

A:

This tests the real business behavior: the test endpoint obtains the finance subnet while guest resources stay isolated. It specifically checks whether the risk that an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain has been reduced. This result addresses the stated challenge at the Brookfield transport facility.

Incorrect Answers

B:

different untagged VLAN handling can leak or misdeliver management and user frames. The offered alternative applies that mechanism: A tagged and untagged test confirms the intended VLAN separation across the link. The reported facts point to a different controlling condition: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. The alternative does not directly settle the required acceptance evidence.

C:

Sample devices show the approved firmware version after a phased compliant upgrade. Its technical scope is explained by: uncontrolled mixed software releases can create inconsistent features and security exposure; a passing acceptance check would show that sample devices show the approved firmware version after a phased compliant upgrade. In this question, the decisive issue is: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. That is why the offered option is not the most direct acceptance evidence.

D:

The option states: The device appears online in the correct site and reports the expected managed configuration. The source describes its associated mechanism as: it requires the team to review site inventory assignments whenever access closets move. By contrast, the current situation is governed by: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 140

At the Brookfield transport facility, a finance workstation receives the guest subnet after moving to a newly configured CX access port. How should the organization sustain the improvement?

  1. Validate trunk tagging assumptions during interface changes
  2. Retest traffic markings after endpoint software updates
  3. Validate peer parameters before routing policy deployments
  4. Audit access VLAN mappings after workstation moves

Explanation

Correct Answer

D:

The needed prevention is to audit access VLAN mappings after workstation moves. It directly sustains the original change to set the intended untagged access VLAN on the endpoint interface and verify its forwarding role. This result addresses the stated challenge at the Brookfield transport facility.

Incorrect Answers

A:

different untagged VLAN handling can leak or misdeliver management and user frames. The offered alternative applies that mechanism: Validate trunk tagging assumptions during interface changes. The reported facts point to a different controlling condition: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. The alternative does not directly settle the required recurrence control.

B:

Retest traffic markings after endpoint software updates. Its technical scope is explained by: a configured policy may not match traffic or may be rewritten further along the path. In this question, the decisive issue is: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. That is why the offered option is not the most direct recurrence control.

C:

The option states: Validate peer parameters before routing policy deployments. The source describes its associated mechanism as: BGP neighbors require compatible AS relationships and reachable transport before exchanging routes, rather than merely a monitoring or presentation issue. By contrast, the current situation is governed by: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. Choosing this alternative would leave the question’s specific recurrence control unresolved.
