Question 150

At the Nortonwood public agency, a redundant campus ring has unexpected blocking because MST regions use different names or revision mappings. Which underlying issue most directly explains this situation?

  1. MST region mismatches change topology interpretation and can select unexpected ports
  2. An incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain
  3. BGP neighbors require compatible AS relationships and reachable transport before exchanging routes
  4. A static next hop that cannot be resolved prevents the default route from forwarding traffic

Explanation

Correct Answer

A:

The evidence indicates that mST region mismatches change topology interpretation and can select unexpected ports. The appropriate response is to align the intended MST region name revision and VLAN-to-instance mapping on participating switches and demonstrate that all intended switches report matching region configuration and stable root paths. This result addresses the stated challenge at the Nortonwood public agency.

Incorrect Answers

B:

An incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. The present question instead depends on this mechanism: mST region mismatches change topology interpretation and can select unexpected ports. That difference matters for the requested root-cause explanation.

C:

BGP neighbors require compatible AS relationships and reachable transport before exchanging routes, rather than merely a monitoring or presentation issue. The offered alternative applies that mechanism: BGP neighbors require compatible AS relationships and reachable transport before exchanging routes. The reported facts point to a different controlling condition: mST region mismatches change topology interpretation and can select unexpected ports. The alternative does not directly settle the required root-cause explanation.

D:

A static next hop that cannot be resolved prevents the default route from forwarding traffic. In this question, the decisive issue is: mST region mismatches change topology interpretation and can select unexpected ports. That is why the offered option is not the most direct root-cause explanation.

Question 151

At the Nortonwood public agency, a redundant campus ring has unexpected blocking because MST regions use different names or revision mappings. What evidence would justify considering this concern addressed?

  1. All intended switches report matching region configuration and stable root paths
  2. The controlled test host reaches its permitted peer through the end-to-end VLAN path
  3. A known user receives the approved role while an unauthorized client is denied or isolated
  4. The allowed management station reaches the switch while a user subnet attempt is blocked

Explanation

Correct Answer

A:

This tests the real business behavior: all intended switches report matching region configuration and stable root paths. It specifically checks whether the risk that mST region mismatches change topology interpretation and can select unexpected ports has been reduced. This result addresses the stated challenge at the Nortonwood public agency.

Incorrect Answers

B:

an established Ethernet link does not imply all tagged VLANs are carried across it, the required evidence must show that the controlled test host reaches its permitted peer through the end-to-end VLAN path. The offered alternative applies that mechanism: The controlled test host reaches its permitted peer through the end-to-end VLAN path. The reported facts point to a different controlling condition: mST region mismatches change topology interpretation and can select unexpected ports. The alternative does not directly settle the required acceptance evidence.

C:

A known user receives the approved role while an unauthorized client is denied or isolated. Its technical scope is explained by: open access ports cannot distinguish authorized identities before granting network privileges. In this question, the decisive issue is: mST region mismatches change topology interpretation and can select unexpected ports. That is why the offered option is not the most direct acceptance evidence.

D:

The allowed management station reaches the switch while a user subnet attempt is blocked. The reported problem is governed by this different mechanism: mST region mismatches change topology interpretation and can select unexpected ports. The offered choice would not address that particular acceptance evidence directly.

Question 152

At the Nortonwood public agency, a redundant campus ring has unexpected blocking because MST regions use different names or revision mappings. How should the organization sustain the improvement?

  1. Validate trunk tagging assumptions during interface changes
  2. Periodically audit MST region digests and spanning tree changes
  3. Review DSCP trust configurations after access role changes
  4. Audit next-hop reachability when WAN addresses change

Explanation

Correct Answer

B:

For the Nortonwood public agency, this maintenance action preserves the fix: periodically audit MST region digests and spanning tree changes. It should be revisited as the workload evolves.

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: mST region mismatches change topology interpretation and can select unexpected ports. The alternative does not directly settle the required recurrence control.

C:

Review DSCP trust configurations after access role changes. The reported problem is governed by this different mechanism: mST region mismatches change topology interpretation and can select unexpected ports. The offered choice would not address that particular recurrence control directly.

D:

Audit next-hop reachability when WAN addresses change. This option is based on the following distinct technical behavior: a static next hop that cannot be resolved prevents the default route from forwarding traffic. The present question instead depends on this mechanism: mST region mismatches change topology interpretation and can select unexpected ports. That difference matters for the requested recurrence control.

Question 153

At the Northport distribution center, a bundled uplink reports only one active member because the peer uses an incompatible aggregation setting. Which approach best resolves the described issue?

  1. Set the intended untagged access VLAN on the endpoint interface and verify its forwarding role
  2. Correct matching LACP group configuration interface speed and peer negotiation on both ends
  3. Match supported transceivers fiber medium and optical parameters at both ends and verify link budget
  4. Create and validate the supported VLAN interface with the correct IP gateway and VLAN operational state

Explanation

Correct Answer

B:

For the Northport distribution center, the appropriate correction is to correct matching LACP group configuration interface speed and peer negotiation on both ends. The decisive reason is that a link aggregation group requires consistent partner settings before members collect and distribute traffic; acceptance evidence is that both links join the active aggregate and service survives one member failure.

Incorrect Answers

A:

Set the intended untagged access VLAN on the endpoint interface and verify its forwarding role. 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 monitor LACP actor partner status after port changes. That is why the offered option is not the most direct root-cause explanation.

C:

Match supported transceivers fiber medium and optical parameters at both ends and verify link budget. This option is based on the following distinct technical behavior: mismatched optic characteristics prevent a valid light path despite correct switch configuration; a passing acceptance check would show that optical diagnostics show receive levels within specification and the link establishes. The present question instead depends on this mechanism: it requires the team to monitor LACP actor partner status after port changes. That difference matters for the requested root-cause explanation.

D:

layer 2 VLAN existence does not by itself supply a routed gateway interface; a passing acceptance check would show that a test host reaches the SVI address and permitted off subnet destinations. The offered alternative applies that mechanism: Create and validate the supported VLAN interface with the correct IP gateway and VLAN operational state. The reported facts point to a different controlling condition: it requires the team to monitor LACP actor partner status after port changes. The alternative does not directly settle the required root-cause explanation.

Question 154

At the Northport distribution center, a bundled uplink reports only one active member because the peer uses an incompatible aggregation setting. Which explanation best accounts for the concern?

  1. A link aggregation group requires consistent partner settings before members collect and distribute traffic
  2. Incorrect VSF stacking links or member configuration can prevent a common logical control plane
  3. Group managed configurations can supersede direct local changes when ownership is not coordinated
  4. A single congested best-effort queue does not protect latency-sensitive voice packets

Explanation

Correct Answer

A:

The strongest explanation is that a link aggregation group requires consistent partner settings before members collect and distribute traffic. This accounts for the outcome and supports the action to correct matching LACP group configuration interface speed and peer negotiation on both ends. This result addresses the stated challenge at the Northport distribution center.

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: it requires the team to monitor LACP actor partner status after port changes. That difference matters for the requested root-cause explanation.

C:

The offered alternative states: Group managed configurations can supersede direct local changes when ownership is not coordinated. The reported facts point to a different controlling condition: it requires the team to monitor LACP actor partner status after port changes. The alternative does not directly settle the required root-cause explanation.

D:

A single congested best-effort queue does not protect latency-sensitive voice packets. In this question, the decisive issue is: it requires the team to monitor LACP actor partner status after port changes. That is why the offered option is not the most direct root-cause explanation.

Question 155

At the Northport distribution center, a bundled uplink reports only one active member because the peer uses an incompatible aggregation setting. Which test result best shows the requirement is met?

  1. All intended switches report matching region configuration and stable root paths
  2. The contractor test reaches its approved exit but cannot route to restricted enterprise subnets
  3. Both links join the active aggregate and service survives one member failure
  4. The BGP session establishes and authorized prefixes appear in the routing policy output

Explanation

Correct Answer

C:

Because a link aggregation group requires consistent partner settings before members collect and distribute traffic, the required evidence must show that both links join the active aggregate and service survives one member failure. A healthy endpoint status alone is insufficient. This result addresses the stated challenge at the Northport distribution center.

Incorrect Answers

A:

All intended switches report matching region configuration and stable root paths. This option is based on the following distinct technical behavior: mST region mismatches change topology interpretation and can select unexpected ports. The present question instead depends on this mechanism: a link aggregation group requires consistent partner settings before members collect and distribute traffic, the required evidence must show that both links join the active aggregate and service survives one member failure. That difference matters for the requested acceptance evidence.

B:

incorrect VRF assignment defeats the intended separation of independent routing contexts. The offered alternative applies that mechanism: The contractor test reaches its approved exit but cannot route to restricted enterprise subnets. The reported facts point to a different controlling condition: a link aggregation group requires consistent partner settings before members collect and distribute traffic, the required evidence must show that both links join the active aggregate and service survives one member failure. The alternative does not directly settle the required acceptance evidence.

D:

The option states: The BGP session establishes and authorized prefixes appear in the routing policy output. 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: a link aggregation group requires consistent partner settings before members collect and distribute traffic, the required evidence must show that both links join the active aggregate and service survives one member failure. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 156

At the Northport distribution center, a bundled uplink reports only one active member because the peer uses an incompatible aggregation setting. Which ongoing control best prevents this issue from recurring?

  1. Review stack topology and split detection before member additions
  2. Review rate thresholds against measured normal guest demand
  3. Audit multicast routing neighbors and reverse path checks after route changes
  4. Monitor LACP actor partner status after port changes

Explanation

Correct Answer

D:

This control works beyond the initial remediation because it requires the team to monitor LACP actor partner status after port changes. This result addresses the stated challenge at the Northport distribution center.

Incorrect Answers

A:

incorrect VSF stacking links or member configuration can prevent a common logical control plane. The offered alternative applies that mechanism: Review stack topology and split detection before member additions. The reported facts point to a different controlling condition: it requires the team to monitor LACP actor partner status after port changes. The alternative does not directly settle the required recurrence control.

B:

Review rate thresholds against measured normal guest demand. Its technical scope is explained by: bursting guest traffic can consume resources needed for contracted business services. In this question, the decisive issue is: it requires the team to monitor LACP actor partner status after port changes. That is why the offered option is not the most direct recurrence control.

C:

The option states: Audit multicast routing neighbors and reverse path checks after route changes. The source describes its associated mechanism as: IGMP local group membership does not automatically create routed multicast forwarding across VLANs. By contrast, the current situation is governed by: it requires the team to monitor LACP actor partner status after port changes. Choosing this alternative would leave the question’s specific recurrence control unresolved.

Question 157

At the Maplehaven school district, a stack expansion uses an unsupported cabling topology and leaves new access switches as independent management units. Which implementation choice best addresses the situation?

  1. Reconfigure supported VSF stack links and member roles according to the hardware topology
  2. Set the intended untagged access VLAN on the endpoint interface and verify its forwarding role
  3. Install a correct default route via the validated reachable next hop and routing context
  4. Deploy a compatible AOS-CX Network Analytics Engine script and agent for the intended state metric

Explanation

Correct Answer

A:

This solution addresses the stated limitation: incorrect VSF stacking links or member configuration can prevent a common logical control plane. Implementing it means the team should reconfigure supported VSF stack links and member roles according to the hardware topology, then verify that all planned members form one healthy stack and recover through a supported link failure. This result addresses the stated challenge at the Maplehaven school district.

Incorrect Answers

B:

The option states: Set the intended untagged access VLAN on the endpoint interface and verify its forwarding role. The source describes its associated mechanism as: an incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. By contrast, the current situation is governed by: incorrect VSF stacking links or member configuration can prevent a common logical control plane. Choosing this alternative would leave the question’s specific implementation unresolved.

C:

Install a correct default route via the validated reachable next hop and routing context. This option is based on the following distinct technical behavior: a static next hop that cannot be resolved prevents the default route from forwarding traffic. The present question instead depends on this mechanism: incorrect VSF stacking links or member configuration can prevent a common logical control plane. That difference matters for the requested implementation.

D:

periodic manual inspection can miss transient fault patterns that require device-local monitoring. The offered alternative applies that mechanism: Deploy a compatible AOS-CX Network Analytics Engine script and agent for the intended state metric. The reported facts point to a different controlling condition: incorrect VSF stacking links or member configuration can prevent a common logical control plane. The alternative does not directly settle the required implementation.

Question 158

At the Maplehaven school district, a stack expansion uses an unsupported cabling topology and leaves new access switches as independent management units. What risk should the team identify as the primary issue?

  1. An incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain
  2. Without common time and device references cross-system event timelines become ambiguous
  3. Incorrect VSF stacking links or member configuration can prevent a common logical control plane
  4. Open access ports cannot distinguish authorized identities before granting network privileges

Explanation

Correct Answer

C:

The evidence indicates that incorrect VSF stacking links or member configuration can prevent a common logical control plane. The appropriate response is to reconfigure supported VSF stack links and member roles according to the hardware topology and demonstrate that all planned members form one healthy stack and recover through a supported link failure. This result addresses the stated challenge at the Maplehaven school district.

Incorrect Answers

A:

The option states: An incorrect access VLAN places untagged endpoint frames into the wrong broadcast domain. By contrast, the current situation is governed by: incorrect VSF stacking links or member configuration can prevent a common logical control plane. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

B:

Without common time and device references cross-system event timelines become ambiguous. The present question instead depends on this mechanism: incorrect VSF stacking links or member configuration can prevent a common logical control plane. That difference matters for the requested root-cause explanation.

D:

Open access ports cannot distinguish authorized identities before granting network privileges. In this question, the decisive issue is: incorrect VSF stacking links or member configuration can prevent a common logical control plane. That is why the offered option is not the most direct root-cause explanation.

Question 159

At the Maplehaven school district, a stack expansion uses an unsupported cabling topology and leaves new access switches as independent management units. What is the strongest acceptance test for this change?

  1. Both links join the active aggregate and service survives one member failure
  2. All planned members form one healthy stack and recover through a supported link failure
  3. A connected host preserves gateway reachability after either peer uplink fails
  4. A receiver gets the approved stream while a nonmember test port sees no unnecessary copy

Explanation

Correct Answer

B:

The team can confirm the fix by showing that all planned members form one healthy stack and recover through a supported link failure. This aligns with the corrective design to reconfigure supported VSF stack links and member roles according to the hardware topology. This result addresses the stated challenge at the Maplehaven school district.

Incorrect Answers

A:

Both links join the active aggregate and service survives one member failure. This option is based on the following distinct technical behavior: a link aggregation group requires consistent partner settings before members collect and distribute traffic, the required evidence must show that both links join the active aggregate and service survives one member failure. The present question instead depends on this mechanism: incorrect VSF stacking links or member configuration can prevent a common logical control plane. That difference matters for the requested acceptance evidence.

C:

A connected host preserves gateway reachability after either peer uplink fails. 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: incorrect VSF stacking links or member configuration can prevent a common logical control plane. That is why the offered option is not the most direct acceptance evidence.

D:

The option states: A receiver gets the approved stream while a nonmember test port sees no unnecessary copy. The source describes its associated mechanism as: without learned receiver groups a Layer 2 multicast stream may be flooded to unrelated ports, the required evidence must show that a receiver gets the approved stream while a nonmember test port sees no unnecessary copy. By contrast, the current situation is governed by: incorrect VSF stacking links or member configuration can prevent a common logical control plane. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 160

At the Maplehaven school district, a stack expansion uses an unsupported cabling topology and leaves new access switches as independent management units. Which setting or practice should be reviewed in future?

  1. Review stack topology and split detection before member additions
  2. Review trunk allowed VLAN lists during service rollout
  3. Retest traffic markings after endpoint software updates
  4. Audit role policy mappings and authentication enforcement after directory changes

Explanation

Correct Answer

A:

After implementation, the team should review stack topology and split detection before member additions as the appropriate recurring safeguard against the identified issue. This result addresses the stated challenge at the Maplehaven school district.

Incorrect Answers

B:

Review trunk allowed VLAN lists during service rollout. Its technical scope is explained by: an established Ethernet link does not imply all tagged VLANs are carried across it, the required evidence must show that the controlled test host reaches its permitted peer through the end-to-end VLAN path. In this question, the decisive issue is: incorrect VSF stacking links or member configuration can prevent a common logical control plane. 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: incorrect VSF stacking links or member configuration can prevent a common logical control plane. Choosing this alternative would leave the question’s specific recurrence control unresolved.

D:

Audit role policy mappings and authentication enforcement after directory changes. This option is based on the following distinct technical behavior: port-only VLAN membership does not express changing identity-driven access requirements reliably, rather than merely a monitoring or presentation issue. The present question instead depends on this mechanism: incorrect VSF stacking links or member configuration can prevent a common logical control plane. That difference matters for the requested recurrence control.
