Question 110

At the Elmhurst transport facility, a technician pastes interface commands at the wrong AOS-CX CLI configuration level and assumes they applied. What risk should the team identify as the primary issue?

  1. A command entered outside the required CLI context may fail or affect a different object
  2. Unsaved live changes may be lost on restart even if forwarding initially works
  3. Total chassis PoE consumption can exceed available power when endpoints start together
  4. A configured policy may not match traffic or may be rewritten further along the path

Explanation

Correct Answer

A:

The situation shows that a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. Remediation is to enter the proper configuration context and confirm the intended interface running configuration. This result addresses the stated challenge at the Elmhurst transport facility.

Incorrect Answers

B:

Unsaved live changes may be lost on restart even if forwarding initially works. The present question instead depends on this mechanism: a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. That difference matters for the requested root-cause explanation.

C:

The offered alternative states: Total chassis PoE consumption can exceed available power when endpoints start together. The reported facts point to a different controlling condition: a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. The alternative does not directly settle the required root-cause explanation.

D:

A configured policy may not match traffic or may be rewritten further along the path. In this question, the decisive issue is: a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. That is why the offered option is not the most direct root-cause explanation.

Question 111

At the Elmhurst transport facility, a technician pastes interface commands at the wrong AOS-CX CLI configuration level and assumes they applied. What is the strongest acceptance test for this change?

  1. An authorized SSH login succeeds while an unauthorized plaintext management attempt fails
  2. Show output confirms the interface setting appears on the exact target port
  3. The controlled test host reaches its permitted peer through the end-to-end VLAN path
  4. Neighbor state reaches Full and expected link state routes are installed

Explanation

Correct Answer

B:

The team can confirm the fix by showing that show output confirms the interface setting appears on the exact target port. This aligns with the corrective design to enter the proper configuration context and confirm the intended interface running configuration. This result addresses the stated challenge at the Elmhurst transport facility.

Incorrect Answers

A:

An authorized SSH login succeeds while an unauthorized plaintext management attempt fails. This option is based on the following distinct technical behavior: 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. The present question instead depends on this mechanism: a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. That difference matters for the requested acceptance evidence.

C:

The controlled test host reaches its permitted peer through the end-to-end VLAN path. 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: a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. That is why the offered option is not the most direct acceptance evidence.

D:

The option states: Neighbor state reaches Full and expected link state routes are installed. 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: a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 112

At the Elmhurst transport facility, a technician pastes interface commands at the wrong AOS-CX CLI configuration level and assumes they applied. Which setting or practice should be reviewed in future?

  1. Add configuration persistence verification to change closure
  2. Monitor authentication failures and certificate lifecycle
  3. Use context-aware configuration reviews and peer verification
  4. Retest traffic markings after endpoint software updates

Explanation

Correct Answer

C:

The team should use context-aware configuration reviews and peer verification. That recurring practice targets the same weakness, namely that a command entered outside the required CLI context may fail or affect a different object. This result addresses the stated challenge at the Elmhurst transport facility.

Incorrect Answers

A:

unsaved live changes may be lost on restart even if forwarding initially works. The offered alternative applies that mechanism: Add configuration persistence verification to change closure. The reported facts point to a different controlling condition: a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. The alternative does not directly settle the required recurrence control.

B:

Monitor authentication failures and certificate lifecycle. Its technical scope is explained by: open access ports cannot distinguish authorized identities before granting network privileges. In this question, the decisive issue is: a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. That is why the offered option is not the most direct recurrence control.

D:

Retest traffic markings after endpoint software updates. This option is based on the following distinct technical behavior: a configured policy may not match traffic or may be rewritten further along the path. The present question instead depends on this mechanism: a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. That difference matters for the requested recurrence control.

Question 113

At the Stonehaven retail infrastructure, a switch works after a live CLI change but reboots into the older VLAN configuration. Which corrective action best meets the requirement?

  1. Enter the proper configuration context and confirm the intended interface running configuration
  2. Implement supported classification and queue scheduling for voice without starving other traffic classes
  3. Feed supported redundant power supplies from independent approved circuits and verify failover
  4. Save and verify the supported persistent configuration after validating the running configuration

Explanation

Correct Answer

D:

For the Stonehaven retail infrastructure, the appropriate correction is to save and verify the supported persistent configuration after validating the running configuration. The decisive reason is that unsaved live changes may be lost on restart even if forwarding initially works; acceptance evidence is that a controlled reboot retains the intended VLAN and uplink settings.

Incorrect Answers

A:

Enter the proper configuration context and confirm the intended interface running configuration. Its technical scope is explained by: a command entered outside the required CLI context may fail or affect a different object; a passing acceptance check would show that show output confirms the interface setting appears on the exact target port. In this question, the decisive issue is: unsaved live changes may be lost on restart even if forwarding initially works. 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: unsaved live changes may be lost on restart even if forwarding initially works. Choosing this alternative would leave the question’s specific implementation unresolved.

C:

Feed supported redundant power supplies from independent approved circuits and verify failover. This option is based on the following distinct technical behavior: two power supplies on one electrical source do not protect against a common circuit failure. The present question instead depends on this mechanism: unsaved live changes may be lost on restart even if forwarding initially works. That difference matters for the requested implementation.

Question 114

At the Stonehaven retail infrastructure, a switch works after a live CLI change but reboots into the older VLAN configuration. Which underlying issue most directly explains this situation?

  1. Unsaved live changes may be lost on restart even if forwarding initially works
  2. A command entered outside the required CLI context may fail or affect a different object
  3. A static next hop that cannot be resolved prevents the default route from forwarding traffic
  4. Shared device administrator credentials prevent strong accountability and selective revocation

Explanation

Correct Answer

A:

The evidence indicates that unsaved live changes may be lost on restart even if forwarding initially works. The appropriate response is to save and verify the supported persistent configuration after validating the running configuration and demonstrate that a controlled reboot retains the intended VLAN and uplink settings. This result addresses the stated challenge at the Stonehaven retail infrastructure.

Incorrect Answers

B:

A command entered outside the required CLI context may fail or affect a different object. This option is based on the following distinct technical behavior: a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. The present question instead depends on this mechanism: unsaved live changes may be lost on restart even if forwarding initially works. That difference matters for the requested root-cause explanation.

C:

The offered alternative states: A static next hop that cannot be resolved prevents the default route from forwarding traffic. The reported facts point to a different controlling condition: unsaved live changes may be lost on restart even if forwarding initially works. The alternative does not directly settle the required root-cause explanation.

D:

Shared device administrator credentials prevent strong accountability and selective revocation. In this question, the decisive issue is: unsaved live changes may be lost on restart even if forwarding initially works. That is why the offered option is not the most direct root-cause explanation.

Question 115

At the Stonehaven retail infrastructure, a switch works after a live CLI change but reboots into the older VLAN configuration. What evidence would justify considering this concern addressed?

  1. Show output confirms the interface setting appears on the exact target port
  2. Both links join the active aggregate and service survives one member failure
  3. A controlled reboot retains the intended VLAN and uplink settings
  4. Under load corporate voice retains its target class while contractor traffic remains best effort

Explanation

Correct Answer

C:

At the Stonehaven retail infrastructure, evidence that a controlled reboot retains the intended VLAN and uplink settings directly validates the correction, instead of testing a neighboring service.

Incorrect Answers

A:

Show output confirms the interface setting appears on the exact target port. This option is based on the following distinct technical behavior: a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. The present question instead depends on this mechanism: unsaved live changes may be lost on restart even if forwarding initially works. That difference matters for the requested acceptance evidence.

B:

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 offered alternative applies that mechanism: Both links join the active aggregate and service survives one member failure. The reported facts point to a different controlling condition: unsaved live changes may be lost on restart even if forwarding initially works. The alternative does not directly settle the required acceptance evidence.

D:

Under load corporate voice retains its target class while contractor traffic remains best effort. The reported problem is governed by this different mechanism: unsaved live changes may be lost on restart even if forwarding initially works. The offered choice would not address that particular acceptance evidence directly.

Question 116

At the Stonehaven retail infrastructure, a switch works after a live CLI change but reboots into the older VLAN configuration. How should the organization sustain the improvement?

  1. Use context-aware configuration reviews and peer verification
  2. Validate peer parameters before routing policy deployments
  3. Add configuration persistence verification to change closure
  4. Monitor control-plane drop and CPU statistics after policy updates

Explanation

Correct Answer

C:

The continuing safeguard is to add configuration persistence verification to change closure. It helps avoid the original condition: unsaved live changes may be lost on restart even if forwarding initially works. This result addresses the stated challenge at the Stonehaven retail infrastructure.

Incorrect Answers

A:

a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. The offered alternative applies that mechanism: Use context-aware configuration reviews and peer verification. The reported facts point to a different controlling condition: unsaved live changes may be lost on restart even if forwarding initially works. The alternative does not directly settle the required recurrence control.

B:

Validate peer parameters before routing policy deployments. 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: unsaved live changes may be lost on restart even if forwarding initially works. That is why the offered option is not the most direct recurrence control.

D:

Monitor control-plane drop and CPU statistics after policy updates. This option is based on the following distinct technical behavior: heavy unsolicited control traffic can contend with essential switch control functions. The present question instead depends on this mechanism: unsaved live changes may be lost on restart even if forwarding initially works. That difference matters for the requested recurrence control.

Question 117

At the Goldport energy utility, an engineer enables unmanaged plaintext remote access for convenient switch configuration. Which approach best resolves the described issue?

  1. Enter the proper configuration context and confirm the intended interface running configuration
  2. Enable the supported SSH-based management path with approved user roles and restrict insecure remote protocols
  3. Permit the required tagged VLAN on the appropriate trunk or uplink interfaces at each end
  4. Verify multicast routing and the supported PIM design between source and receiver networks

Explanation

Correct Answer

B:

For the Goldport energy utility, the appropriate correction is to enable the supported SSH-based management path with approved user roles and restrict insecure remote protocols. The decisive reason is that unencrypted or broadly reachable management exposes network configuration and credentials; acceptance evidence is that an authorized SSH login succeeds while an unauthorized plaintext management attempt fails.

Incorrect Answers

A:

Enter the proper configuration context and confirm the intended interface running configuration. Its technical scope is explained by: a command entered outside the required CLI context may fail or affect a different object; a passing acceptance check would show that show output confirms the interface setting appears on the exact target port. In this question, the decisive issue is: 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. That is why the offered option is not the most direct root-cause explanation.

C:

Permit the required tagged VLAN on the appropriate trunk or uplink interfaces at each end. This option is based on the following distinct technical behavior: an established Ethernet link does not imply all tagged VLANs are carried across it. The present question instead depends on this mechanism: 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. That difference matters for the requested root-cause explanation.

D:

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. The offered alternative applies that mechanism: Verify multicast routing and the supported PIM design between source and receiver networks. The reported facts point to a different controlling condition: 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. The alternative does not directly settle the required root-cause explanation.

Question 118

At the Goldport energy utility, an engineer enables unmanaged plaintext remote access for convenient switch configuration. Which explanation best accounts for the concern?

  1. A command entered outside the required CLI context may fail or affect a different object
  2. Layer 3 separation blocks local broadcast discovery without an approved relay path
  3. Unencrypted or broadly reachable management exposes network configuration and credentials
  4. OSPF path selection follows its calculated metrics rather than business labels on ports

Explanation

Correct Answer

C:

The situation shows that unencrypted or broadly reachable management exposes network configuration and credentials, rather than merely a monitoring or presentation issue. Remediation is to enable the supported SSH-based management path with approved user roles and restrict insecure remote protocols. This result addresses the stated challenge at the Goldport energy utility.

Incorrect Answers

A:

The option states: A command entered outside the required CLI context may fail or affect a different object. The source describes its associated mechanism as: a command entered outside the required CLI context may fail or affect a different object, rather than merely a monitoring or presentation issue. By contrast, the current situation is governed by: unencrypted or broadly reachable management exposes network configuration and credentials, rather than merely a monitoring or presentation issue. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

B:

Layer 3 separation blocks local broadcast discovery without an approved relay path. This option is based on the following distinct technical behavior: layer 3 separation blocks local broadcast discovery without an approved relay path, the required evidence must show that a test client receives the correct scope address and relay logs show the exchange. The present question instead depends on this mechanism: unencrypted or broadly reachable management exposes network configuration and credentials, rather than merely a monitoring or presentation issue. That difference matters for the requested root-cause explanation.

D:

OSPF path selection follows its calculated metrics rather than business labels on ports. In this question, the decisive issue is: unencrypted or broadly reachable management exposes network configuration and credentials, rather than merely a monitoring or presentation issue. That is why the offered option is not the most direct root-cause explanation.

Question 119

At the Goldport energy utility, an engineer enables unmanaged plaintext remote access for convenient switch configuration. Which test result best shows the requirement is met?

  1. A controlled reboot retains the intended VLAN and uplink settings
  2. A test client receives the correct scope address and relay logs show the exchange
  3. An authorized SSH login succeeds while an unauthorized plaintext management attempt fails
  4. Under load corporate voice retains its target class while contractor traffic remains best effort

Explanation

Correct Answer

C:

Because 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. A healthy endpoint status alone is insufficient. This result addresses the stated challenge at the Goldport energy utility.

Incorrect Answers

A:

A controlled reboot retains the intended VLAN and uplink settings. This option is based on the following distinct technical behavior: unsaved live changes may be lost on restart even if forwarding initially works. The present question instead depends on this mechanism: 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. That difference matters for the requested acceptance evidence.

B:

layer 3 separation blocks local broadcast discovery without an approved relay path, the required evidence must show that a test client receives the correct scope address and relay logs show the exchange. The offered alternative applies that mechanism: A test client receives the correct scope address and relay logs show the exchange. The reported facts point to a different controlling condition: 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. The alternative does not directly settle the required acceptance evidence.

D:

Under load corporate voice retains its target class while contractor traffic remains best effort. The reported problem is governed by this different mechanism: 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. The offered choice would not address that particular acceptance evidence directly.

Question 120

At the Goldport energy utility, an engineer enables unmanaged plaintext remote access for convenient switch configuration. Which ongoing control best prevents this issue from recurring?

  1. Add configuration persistence verification to change closure
  2. Audit management protocols and trusted access sources during upgrades
  3. Validate trunk tagging assumptions during interface changes
  4. Review rate thresholds against measured normal guest demand

Explanation

Correct Answer

B:

The needed prevention is to audit management protocols and trusted access sources during upgrades. It directly sustains the original change to enable the supported SSH-based management path with approved user roles and restrict insecure remote protocols. This result addresses the stated challenge at the Goldport energy utility.

Incorrect Answers

A:

unsaved live changes may be lost on restart even if forwarding initially works. The offered alternative applies that mechanism: Add configuration persistence verification to change closure. The reported facts point to a different controlling condition: 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. The alternative does not directly settle the required recurrence control.

C:

The option states: Validate trunk tagging assumptions during interface changes. The source describes its associated mechanism as: different untagged VLAN handling can leak or misdeliver management and user frames. By contrast, the current situation is governed by: 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. Choosing this alternative would leave the question’s specific recurrence control unresolved.

D:

Review rate thresholds against measured normal guest demand. This option is based on the following distinct technical behavior: bursting guest traffic can consume resources needed for contracted business services. The present question instead depends on this mechanism: 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. That difference matters for the requested recurrence control.
