Question 240

At the Willowford telecommunications company, network administrators share one local privileged account across all switches making actions untraceable. Which ongoing control best prevents this issue from recurring?

  1. Review AAA fallback and administrative role mappings quarterly
  2. Monitor VSX consistency and active gateway status after releases
  3. Alert on OSPF neighbor down events and compare interface templates
  4. Review stack topology and split detection before member additions

Explanation

Correct Answer

A:

The continuing safeguard is to review AAA fallback and administrative role mappings quarterly. It helps avoid the original condition: shared device administrator credentials prevent strong accountability and selective revocation. This result addresses the stated challenge at the Willowford telecommunications company.

Incorrect Answers

B:

Monitor VSX consistency and active gateway status after releases. Its technical scope is explained by: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. In this question, the decisive issue is: shared device administrator credentials prevent strong accountability and selective revocation. That is why the offered option is not the most direct recurrence control.

C:

The option states: Alert on OSPF neighbor down events and compare interface templates. The source describes its associated mechanism as: 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. By contrast, the current situation is governed by: shared device administrator credentials prevent strong accountability and selective revocation. Choosing this alternative would leave the question’s specific recurrence control unresolved.

D:

Review stack topology and split detection before member additions. This option is based on the following distinct technical behavior: incorrect VSF stacking links or member configuration can prevent a common logical control plane. The present question instead depends on this mechanism: shared device administrator credentials prevent strong accountability and selective revocation. That difference matters for the requested recurrence control.

Question 241

At the Pinewick data center, a dual distribution pair intermittently forwards routed client traffic incorrectly after an active-gateway misconfiguration. Which implementation choice best addresses the situation?

  1. Deploy a compatible AOS-CX Network Analytics Engine script and agent for the intended state metric
  2. Use a governed MAC authentication fallback or equivalent device onboarding policy with restricted authorization
  3. Align supported VSX active gateway configuration addresses and consistency on both peers
  4. Inspect the classification rules DSCP mappings and per-queue counters at each relevant hop

Explanation

Correct Answer

C:

This is the direct HPE Aruba wired switching remedy: align supported VSX active gateway configuration addresses and consistency on both peers. The observed risk is that dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding; a passing acceptance check would show that a connected host preserves gateway reachability after either peer uplink fails. This result addresses the stated challenge at the Pinewick data center.

Incorrect Answers

A:

Deploy a compatible AOS-CX Network Analytics Engine script and agent for the intended state metric. Its technical scope is explained by: periodic manual inspection can miss transient fault patterns that require device-local monitoring. In this question, the decisive issue is: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding; a passing acceptance check would show that a connected host preserves gateway reachability after either peer uplink fails. That is why the offered option is not the most direct implementation.

B:

The option states: Use a governed MAC authentication fallback or equivalent device onboarding policy with restricted authorization. The source describes its associated mechanism as: a device without an EAP supplicant cannot complete the chosen port identity protocol. By contrast, the current situation is governed by: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding; a passing acceptance check would show that a connected host preserves gateway reachability after either peer uplink fails. Choosing this alternative would leave the question’s specific implementation unresolved.

D:

a configured policy may not match traffic or may be rewritten further along the path. The offered alternative applies that mechanism: Inspect the classification rules DSCP mappings and per-queue counters at each relevant hop. The reported facts point to a different controlling condition: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding; a passing acceptance check would show that a connected host preserves gateway reachability after either peer uplink fails. The alternative does not directly settle the required implementation.

Question 242

At the Pinewick data center, a dual distribution pair intermittently forwards routed client traffic incorrectly after an active-gateway misconfiguration. What risk should the team identify as the primary issue?

  1. Periodic manual inspection can miss transient fault patterns that require device-local monitoring
  2. An incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain
  3. Dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding
  4. A physical breakout requires matched hardware and operating mode rather than only an interface name

Explanation

Correct Answer

C:

The evidence indicates that dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. The appropriate response is to align supported VSX active gateway configuration addresses and consistency on both peers and demonstrate that a connected host preserves gateway reachability after either peer uplink fails. This result addresses the stated challenge at the Pinewick data center.

Incorrect Answers

A:

The option states: Periodic manual inspection can miss transient fault patterns that require device-local monitoring. By contrast, the current situation is governed by: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

B:

An incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. The present question instead depends on this mechanism: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. That difference matters for the requested root-cause explanation.

D:

A physical breakout requires matched hardware and operating mode rather than only an interface name. In this question, the decisive issue is: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. That is why the offered option is not the most direct root-cause explanation.

Question 243

At the Pinewick data center, a dual distribution pair intermittently forwards routed client traffic incorrectly after an active-gateway misconfiguration. What is the strongest acceptance test for this change?

  1. A test port event appears with matching switch identity and timestamp in monitoring
  2. All planned members form one healthy stack and recover through a supported link failure
  3. Traffic generators show guest bursts are limited while approved office flows pass
  4. A connected host preserves gateway reachability after either peer uplink fails

Explanation

Correct Answer

D:

The intended correction is to align supported VSX active gateway configuration addresses and consistency on both peers. The decisive verification is that a connected host preserves gateway reachability after either peer uplink fails, rather than only confirming configuration was saved. This result addresses the stated challenge at the Pinewick data center.

Incorrect Answers

A:

A test port event appears with matching switch identity and timestamp in monitoring. This option is based on the following distinct technical behavior: it requires the team to verify log retention and time synchronization after management changes. The present question instead depends on this mechanism: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. That difference matters for the requested acceptance evidence.

B:

incorrect VSF stacking links or member configuration can prevent a common logical control plane. The offered alternative applies that mechanism: All planned members form one healthy stack and recover through a supported link failure. The reported facts point to a different controlling condition: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. The alternative does not directly settle the required acceptance evidence.

C:

Traffic generators show guest bursts are limited while approved office flows pass. Its technical scope is explained by: bursting guest traffic can consume resources needed for contracted business services. In this question, the decisive issue is: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. That is why the offered option is not the most direct acceptance evidence.

Question 244

At the Pinewick data center, a dual distribution pair intermittently forwards routed client traffic incorrectly after an active-gateway misconfiguration. Which setting or practice should be reviewed in future?

  1. Verify log retention and time synchronization after management changes
  2. Monitor LACP actor partner status after port changes
  3. Monitor VSX consistency and active gateway status after releases
  4. Review firmware exceptions and rollout failures on a defined schedule

Explanation

Correct Answer

C:

The team should monitor VSX consistency and active gateway status after releases. That recurring practice targets the same weakness, namely that dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. This result addresses the stated challenge at the Pinewick data center.

Incorrect Answers

A:

it requires the team to verify log retention and time synchronization after management changes. The offered alternative applies that mechanism: Verify log retention and time synchronization after management changes. The reported facts point to a different controlling condition: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. The alternative does not directly settle the required recurrence control.

B:

Monitor LACP actor partner status after port changes. Its technical scope is explained by: it requires the team to monitor LACP actor partner status after port changes. In this question, the decisive issue is: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. That is why the offered option is not the most direct recurrence control.

D:

Review firmware exceptions and rollout failures on a defined schedule. This option is based on the following distinct technical behavior: 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. The present question instead depends on this mechanism: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. That difference matters for the requested recurrence control.

Question 245

At the Birchhaven municipal network, an access switch connects to two VSX distribution devices but one side is configured as an unrelated standalone port. Which corrective action best meets the requirement?

  1. Configure the supported VSX multi-chassis LAG coherently across both peers and the downstream device
  2. Integrate supported event logging and Central monitoring with synchronized time and device identity
  3. Align the intended MST region name revision and VLAN-to-instance mapping on participating switches
  4. Use a governed MAC authentication fallback or equivalent device onboarding policy with restricted authorization

Explanation

Correct Answer

A:

This is the direct HPE Aruba wired switching remedy: configure the supported VSX multi-chassis LAG coherently across both peers and the downstream device. The observed risk is that a mismatched multi-chassis aggregation can create blocked members or forwarding loops; a passing acceptance check would show that both uplinks carry the approved aggregate and the path recovers after a peer failure. This result addresses the stated challenge at the Birchhaven municipal network.

Incorrect Answers

B:

The option states: Integrate supported event logging and Central monitoring with synchronized time and device identity. The source describes its associated mechanism as: without common time and device references cross-system event timelines become ambiguous. By contrast, the current situation is governed by: a mismatched multi-chassis aggregation can create blocked members or forwarding loops; a passing acceptance check would show that both uplinks carry the approved aggregate and the path recovers after a peer failure. Choosing this alternative would leave the question’s specific implementation unresolved.

C:

Align the intended MST region name revision and VLAN-to-instance mapping on participating switches. This option is based on the following distinct technical behavior: mST region mismatches change topology interpretation and can select unexpected ports; a passing acceptance check would show that all intended switches report matching region configuration and stable root paths. The present question instead depends on this mechanism: a mismatched multi-chassis aggregation can create blocked members or forwarding loops; a passing acceptance check would show that both uplinks carry the approved aggregate and the path recovers after a peer failure. That difference matters for the requested implementation.

D:

a device without an EAP supplicant cannot complete the chosen port identity protocol. The offered alternative applies that mechanism: Use a governed MAC authentication fallback or equivalent device onboarding policy with restricted authorization. The reported facts point to a different controlling condition: a mismatched multi-chassis aggregation can create blocked members or forwarding loops; a passing acceptance check would show that both uplinks carry the approved aggregate and the path recovers after a peer failure. The alternative does not directly settle the required implementation.

Question 246

At the Birchhaven municipal network, an access switch connects to two VSX distribution devices but one side is configured as an unrelated standalone port. Which underlying issue most directly explains this situation?

  1. A mismatched multi-chassis aggregation can create blocked members or forwarding loops
  2. Dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding
  3. Unsaved live changes may be lost on restart even if forwarding initially works
  4. Heavy unsolicited control traffic can contend with essential switch control functions

Explanation

Correct Answer

A:

The evidence indicates that a mismatched multi-chassis aggregation can create blocked members or forwarding loops. The appropriate response is to configure the supported VSX multi-chassis LAG coherently across both peers and the downstream device and demonstrate that both uplinks carry the approved aggregate and the path recovers after a peer failure. This result addresses the stated challenge at the Birchhaven municipal network.

Incorrect Answers

B:

Dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. The present question instead depends on this mechanism: a mismatched multi-chassis aggregation can create blocked members or forwarding loops. That difference matters for the requested root-cause explanation.

C:

The offered alternative states: Unsaved live changes may be lost on restart even if forwarding initially works. The reported facts point to a different controlling condition: a mismatched multi-chassis aggregation can create blocked members or forwarding loops. The alternative does not directly settle the required root-cause explanation.

D:

Heavy unsolicited control traffic can contend with essential switch control functions. In this question, the decisive issue is: a mismatched multi-chassis aggregation can create blocked members or forwarding loops. That is why the offered option is not the most direct root-cause explanation.

Question 247

At the Birchhaven municipal network, an access switch connects to two VSX distribution devices but one side is configured as an unrelated standalone port. What evidence would justify considering this concern addressed?

  1. A connected host preserves gateway reachability after either peer uplink fails
  2. All intended breakout links negotiate supported speed and pass connectivity tests
  3. Removing one approved circuit leaves forwarding and required modules operational
  4. Both uplinks carry the approved aggregate and the path recovers after a peer failure

Explanation

Correct Answer

D:

This is the relevant acceptance result: both uplinks carry the approved aggregate and the path recovers after a peer failure. It demonstrates the outcome of choosing to configure the supported VSX multi-chassis LAG coherently across both peers and the downstream device. This result addresses the stated challenge at the Birchhaven municipal network.

Incorrect Answers

A:

A connected host preserves gateway reachability after either peer uplink fails. This option is based on the following distinct technical behavior: dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. The present question instead depends on this mechanism: a mismatched multi-chassis aggregation can create blocked members or forwarding loops. That difference matters for the requested acceptance evidence.

B:

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 offered alternative applies that mechanism: All intended breakout links negotiate supported speed and pass connectivity tests. The reported facts point to a different controlling condition: a mismatched multi-chassis aggregation can create blocked members or forwarding loops. The alternative does not directly settle the required acceptance evidence.

C:

Removing one approved circuit leaves forwarding and required modules operational. Its technical scope is explained by: it requires the team to audit power source diversity and module status during site inspections. In this question, the decisive issue is: a mismatched multi-chassis aggregation can create blocked members or forwarding loops. That is why the offered option is not the most direct acceptance evidence.

Question 248

At the Birchhaven municipal network, an access switch connects to two VSX distribution devices but one side is configured as an unrelated standalone port. How should the organization sustain the improvement?

  1. Review AAA fallback and administrative role mappings quarterly
  2. Review cost design after link-speed upgrades
  3. Audit VSX LAG identifiers peer consistency and actor status
  4. Review DSCP trust configurations after access role changes

Explanation

Correct Answer

C:

The continuing safeguard is to audit VSX LAG identifiers peer consistency and actor status. It helps avoid the original condition: a mismatched multi-chassis aggregation can create blocked members or forwarding loops. This result addresses the stated challenge at the Birchhaven municipal network.

Incorrect Answers

A:

shared device administrator credentials prevent strong accountability and selective revocation. The offered alternative applies that mechanism: Review AAA fallback and administrative role mappings quarterly. The reported facts point to a different controlling condition: a mismatched multi-chassis aggregation can create blocked members or forwarding loops. The alternative does not directly settle the required recurrence control.

B:

Review cost design after link-speed upgrades. Its technical scope is explained by: OSPF path selection follows its calculated metrics rather than business labels on ports. In this question, the decisive issue is: a mismatched multi-chassis aggregation can create blocked members or forwarding loops. That is why the offered option is not the most direct recurrence control.

D:

Review DSCP trust configurations after access role changes. The reported problem is governed by this different mechanism: a mismatched multi-chassis aggregation can create blocked members or forwarding loops. The offered choice would not address that particular recurrence control directly.

Question 249

At the Oakport customer service center, the helpdesk sees Central alerts but has no correlation to switch interface events during incidents. Which approach best resolves the described issue?

  1. Configure supported RADIUS connectivity and identity policy integration with ClearPass or the approved AAA service
  2. Verify multicast routing and the supported PIM design between source and receiver networks
  3. Set the approved trust boundary and re-mark untrusted traffic according to port and policy
  4. Integrate supported event logging and Central monitoring with synchronized time and device identity

Explanation

Correct Answer

D:

Integrate supported event logging and Central monitoring with synchronized time and device identity is the best response because without common time and device references cross-system event timelines become ambiguous. A focused validation would establish that a test port event appears with matching switch identity and timestamp in monitoring. This result addresses the stated challenge at the Oakport customer service center.

Incorrect Answers

A:

Configure supported RADIUS connectivity and identity policy integration with ClearPass or the approved AAA service. Its technical scope is explained by: wired authentication cannot authorize users if switch and server trust or reachability is missing. In this question, the decisive issue is: without common time and device references cross-system event timelines become ambiguous. That is why the offered option is not the most direct root-cause explanation.

B:

The option states: Verify multicast routing and the supported PIM design between source and receiver networks. The source describes its associated mechanism as: IGMP local group membership does not automatically create routed multicast forwarding across VLANs; a passing acceptance check would show that a routed subscriber receives the expected group through the authorized multicast tree. By contrast, the current situation is governed by: without common time and device references cross-system event timelines become ambiguous. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

C:

Set the approved trust boundary and re-mark untrusted traffic according to port and policy. The reported problem is governed by this different mechanism: without common time and device references cross-system event timelines become ambiguous. The offered choice would not address that particular root-cause explanation directly.

Question 250

At the Oakport customer service center, the helpdesk sees Central alerts but has no correlation to switch interface events during incidents. Which explanation best accounts for the concern?

  1. Dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding
  2. Without learned receiver groups a Layer 2 multicast stream may be flooded to unrelated ports
  3. An established Ethernet link does not imply all tagged VLANs are carried across it
  4. Without common time and device references cross-system event timelines become ambiguous

Explanation

Correct Answer

D:

This identifies the root issue: without common time and device references cross-system event timelines become ambiguous. At the Oakport customer service center, the team should therefore integrate supported event logging and Central monitoring with synchronized time and device identity.

Incorrect Answers

A:

The option states: Dual switch gateway services require coordinated configuration to prevent inconsistent L3 forwarding. By contrast, the current situation is governed by: without common time and device references cross-system event timelines become ambiguous. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

B:

Without learned receiver groups a Layer 2 multicast stream may be flooded to unrelated ports. This option is based on the following distinct technical behavior: without learned receiver groups a Layer 2 multicast stream may be flooded to unrelated ports, rather than merely a monitoring or presentation issue. The present question instead depends on this mechanism: without common time and device references cross-system event timelines become ambiguous. That difference matters for the requested root-cause explanation.

C:

The offered alternative states: An established Ethernet link does not imply all tagged VLANs are carried across it. The reported facts point to a different controlling condition: without common time and device references cross-system event timelines become ambiguous. The alternative does not directly settle the required root-cause explanation.
