Question 430

At the Glenbrook school district, a regional outage destroys a network file server that held the only copies of switch configurations. Which explanation best accounts for the concern?

  1. Peer configuration drift can produce different forwarding and security outcomes after failover
  2. The number of link-up ports cannot reveal whether powered endpoints face imminent overload
  3. Backups co-located with the failed site cannot support restoration after a regional disaster
  4. Snapshot route presence can conceal unstable sessions and transient packet loss

Explanation

Correct Answer

C:

The situation shows that backups co-located with the failed site cannot support restoration after a regional disaster, rather than merely a monitoring or presentation issue. Remediation is to store encrypted configuration recovery copies in an independent approved offsite repository. This result addresses the stated challenge at the Glenbrook school district.

Incorrect Answers

A:

The option states: Peer configuration drift can produce different forwarding and security outcomes after failover. By contrast, the current situation is governed by: backups co-located with the failed site cannot support restoration after a regional disaster, rather than merely a monitoring or presentation issue. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

B:

The number of link-up ports cannot reveal whether powered endpoints face imminent overload. The present question instead depends on this mechanism: backups co-located with the failed site cannot support restoration after a regional disaster, rather than merely a monitoring or presentation issue. That difference matters for the requested root-cause explanation.

D:

Snapshot route presence can conceal unstable sessions and transient packet loss. The reported problem is governed by this different mechanism: backups co-located with the failed site cannot support restoration after a regional disaster, rather than merely a monitoring or presentation issue. The offered choice would not address that particular root-cause explanation directly.

Question 431

At the Glenbrook school district, a regional outage destroys a network file server that held the only copies of switch configurations. Which test result best shows the requirement is met?

  1. A compliance report flags a seeded unauthorized setting while permitting approved site differences
  2. A forecast predicts the upgrade threshold before expected user and application growth
  3. An OSPF reset fixture generates the correct neighbor stability alert
  4. A recovery exercise retrieves the latest approved switch configuration from outside the affected site

Explanation

Correct Answer

D:

The team can confirm the fix by showing that a recovery exercise retrieves the latest approved switch configuration from outside the affected site. This aligns with the corrective design to store encrypted configuration recovery copies in an independent approved offsite repository. This result addresses the stated challenge at the Glenbrook school district.

Incorrect Answers

A:

A compliance report flags a seeded unauthorized setting while permitting approved site differences. This option is based on the following distinct technical behavior: configuration drift increases security exposure and incident uncertainty between otherwise similar sites. The present question instead depends on this mechanism: backups co-located with the failed site cannot support restoration after a regional disaster, rather than merely a monitoring or presentation issue. That difference matters for the requested acceptance evidence.

B:

average throughput obscures repeated peaks and does not establish adequate burst headroom, the required evidence must show that a forecast predicts the upgrade threshold before expected user and application growth. The offered alternative applies that mechanism: A forecast predicts the upgrade threshold before expected user and application growth. The reported facts point to a different controlling condition: backups co-located with the failed site cannot support restoration after a regional disaster, rather than merely a monitoring or presentation issue. The alternative does not directly settle the required acceptance evidence.

C:

An OSPF reset fixture generates the correct neighbor stability alert. The reported problem is governed by this different mechanism: backups co-located with the failed site cannot support restoration after a regional disaster, rather than merely a monitoring or presentation issue. The offered choice would not address that particular acceptance evidence directly.

Question 432

At the Glenbrook school district, a regional outage destroys a network file server that held the only copies of switch configurations. Which ongoing control best prevents this issue from recurring?

  1. Review scope membership and template diffs before deployment
  2. Test geographic backup recovery and retention expiration twice yearly
  3. Monitor client authentication time and service dependencies
  4. Track ISL capacity peer events and redundancy targets

Explanation

Correct Answer

B:

The needed prevention is to test geographic backup recovery and retention expiration twice yearly. It directly sustains the original change to store encrypted configuration recovery copies in an independent approved offsite repository. This result addresses the stated challenge at the Glenbrook school district.

Incorrect Answers

A:

a global or group template change may affect more devices than the operator expects, rather than merely a monitoring or presentation issue. The offered alternative applies that mechanism: Review scope membership and template diffs before deployment. The reported facts point to a different controlling condition: backups co-located with the failed site cannot support restoration after a regional disaster, rather than merely a monitoring or presentation issue. The alternative does not directly settle the required recurrence control.

C:

The option states: Monitor client authentication time and service dependencies. The source describes its associated mechanism as: user experience can degrade in identity services even with healthy switching and routing. By contrast, the current situation is governed by: backups co-located with the failed site cannot support restoration after a regional disaster, rather than merely a monitoring or presentation issue. Choosing this alternative would leave the question’s specific recurrence control unresolved.

D:

Track ISL capacity peer events and redundancy targets. This option is based on the following distinct technical behavior: it requires the team to track ISL capacity peer events and redundancy targets. The present question instead depends on this mechanism: backups co-located with the failed site cannot support restoration after a regional disaster, rather than merely a monitoring or presentation issue. That difference matters for the requested recurrence control.

Question 433

At the Thornfield media production office, a campus uplink has slowly increasing discarded packets but the daily health report shows only whether the link is up. Which implementation choice best addresses the situation?

  1. Inspect neighbor event history adjacency uptime and relevant interface logs instead of only the routing table
  2. Query the switch for supported REST API versions and use the appropriate supported version or latest path
  3. Verify HTTPS server availability and REST access on the intended management VRF with authorized client connectivity
  4. Trend interface discards error counters and utilization to select the appropriate remediation threshold

Explanation

Correct Answer

D:

The primary failure mode is that binary link state can hide progressive congestion and packet-quality degradation. The proposed action directly fixes it by requiring the team to trend interface discards error counters and utilization to select the appropriate remediation threshold; afterward, verify that a dashboard alert fires for a seeded sustained discard increase before an application outage. This result addresses the stated challenge at the Thornfield media production office.

Incorrect Answers

A:

Inspect neighbor event history adjacency uptime and relevant interface logs instead of only the routing table. The reported problem is governed by this different mechanism: binary link state can hide progressive congestion and packet-quality degradation. The offered choice would not address that particular implementation directly.

B:

The option states: Query the switch for supported REST API versions and use the appropriate supported version or latest path. The source describes its associated mechanism as: aPI resource version availability can differ between AOS-CX software releases and platforms. By contrast, the current situation is governed by: binary link state can hide progressive congestion and packet-quality degradation. Choosing this alternative would leave the question’s specific implementation unresolved.

C:

Verify HTTPS server availability and REST access on the intended management VRF with authorized client connectivity. This option is based on the following distinct technical behavior: REST requests require the appropriate management service exposure and reachability beyond the presence of SSH. The present question instead depends on this mechanism: binary link state can hide progressive congestion and packet-quality degradation. That difference matters for the requested implementation.

Question 434

At the Thornfield media production office, a campus uplink has slowly increasing discarded packets but the daily health report shows only whether the link is up. What risk should the team identify as the primary issue?

  1. Snapshot route presence can conceal unstable sessions and transient packet loss
  2. A global or group template change may affect more devices than the operator expects
  3. Binary link state can hide progressive congestion and packet-quality degradation
  4. REST sessions and tokens must be established and refreshed according to platform security requirements

Explanation

Correct Answer

C:

The evidence indicates that binary link state can hide progressive congestion and packet-quality degradation. The appropriate response is to trend interface discards error counters and utilization to select the appropriate remediation threshold and demonstrate that a dashboard alert fires for a seeded sustained discard increase before an application outage. This result addresses the stated challenge at the Thornfield media production office.

Incorrect Answers

A:

Snapshot route presence can conceal unstable sessions and transient packet loss. The reported problem is governed by this different mechanism: binary link state can hide progressive congestion and packet-quality degradation. The offered choice would not address that particular root-cause explanation directly.

B:

A global or group template change may affect more devices than the operator expects. This option is based on the following distinct technical behavior: a global or group template change may affect more devices than the operator expects, rather than merely a monitoring or presentation issue. The present question instead depends on this mechanism: binary link state can hide progressive congestion and packet-quality degradation. That difference matters for the requested root-cause explanation.

D:

REST sessions and tokens must be established and refreshed according to platform security requirements. The reported problem is governed by this different mechanism: binary link state can hide progressive congestion and packet-quality degradation. The offered choice would not address that particular root-cause explanation directly.

Question 435

At the Thornfield media production office, a campus uplink has slowly increasing discarded packets but the daily health report shows only whether the link is up. What is the strongest acceptance test for this change?

  1. A captured resource spike correlates with the affected process and application behavior
  2. A test restore identifies unsupported features and re-establishes intended forwarding
  3. A dashboard alert fires for a seeded sustained discard increase before an application outage
  4. A pilot site receives only the intended changes and other sites retain baseline service

Explanation

Correct Answer

C:

This tests the real business behavior: a dashboard alert fires for a seeded sustained discard increase before an application outage. It specifically checks whether the risk that binary link state can hide progressive congestion and packet-quality degradation has been reduced. This result addresses the stated challenge at the Thornfield media production office.

Incorrect Answers

A:

A captured resource spike correlates with the affected process and application behavior. This option is based on the following distinct technical behavior: it requires the team to track resource baselines and software version regressions. The present question instead depends on this mechanism: binary link state can hide progressive congestion and packet-quality degradation. That difference matters for the requested acceptance evidence.

B:

a backup from different hardware or release cannot be assumed directly reusable, the required evidence must show that a test restore identifies unsupported features and re-establishes intended forwarding. The offered alternative applies that mechanism: A test restore identifies unsupported features and re-establishes intended forwarding. The reported facts point to a different controlling condition: binary link state can hide progressive congestion and packet-quality degradation. The alternative does not directly settle the required acceptance evidence.

D:

The option states: A pilot site receives only the intended changes and other sites retain baseline service. The source describes its associated mechanism as: a global or group template change may affect more devices than the operator expects, rather than merely a monitoring or presentation issue. By contrast, the current situation is governed by: binary link state can hide progressive congestion and packet-quality degradation. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 436

At the Thornfield media production office, a campus uplink has slowly increasing discarded packets but the daily health report shows only whether the link is up. Which setting or practice should be reviewed in future?

  1. Baseline interface error rates and investigate persistent deviations
  2. Reassess power reserve when new cameras or access points deploy
  3. Compare switches to the baseline after every change window
  4. Review credential handling token expiry and audit logs during automation updates

Explanation

Correct Answer

A:

After implementation, the team should baseline interface error rates and investigate persistent deviations as the appropriate recurring safeguard against the identified issue. This result addresses the stated challenge at the Thornfield media production office.

Incorrect Answers

B:

Reassess power reserve when new cameras or access points deploy. Its technical scope is explained by: the number of link-up ports cannot reveal whether powered endpoints face imminent overload. In this question, the decisive issue is: binary link state can hide progressive congestion and packet-quality degradation. That is why the offered option is not the most direct recurrence control.

C:

The option states: Compare switches to the baseline after every change window. The source describes its associated mechanism as: configuration drift increases security exposure and incident uncertainty between otherwise similar sites. By contrast, the current situation is governed by: binary link state can hide progressive congestion and packet-quality degradation. Choosing this alternative would leave the question’s specific recurrence control unresolved.

D:

Review credential handling token expiry and audit logs during automation updates. The reported problem is governed by this different mechanism: binary link state can hide progressive congestion and packet-quality degradation. The offered choice would not address that particular recurrence control directly.

Question 437

At the Highbridge transport facility, an important fiber link remains up but its optical receive power steadily approaches the transceiver threshold. Which corrective action best meets the requirement?

  1. Trend interface discards error counters and utilization to select the appropriate remediation threshold
  2. Review VSX consistency and align relevant configuration under a controlled dual-peer change procedure
  3. Trend receive power and temperature against supported optics specifications and schedule proactive remediation
  4. Verify HTTPS server availability and REST access on the intended management VRF with authorized client connectivity

Explanation

Correct Answer

C:

The reported facts support this change rather than a general platform replacement. The team should trend receive power and temperature against supported optics specifications and schedule proactive remediation because a link can appear operational until optical margins deteriorate enough to cause intermittent failure. A suitable test confirms that an early warning triggers before the test link reaches the specified optical threshold. This result addresses the stated challenge at the Highbridge transport facility.

Incorrect Answers

A:

Trend interface discards error counters and utilization to select the appropriate remediation threshold. Its technical scope is explained by: binary link state can hide progressive congestion and packet-quality degradation. In this question, the decisive issue is: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. That is why the offered option is not the most direct implementation.

B:

The option states: Review VSX consistency and align relevant configuration under a controlled dual-peer change procedure. The source describes its associated mechanism as: peer configuration drift can produce different forwarding and security outcomes after failover. By contrast, the current situation is governed by: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. Choosing this alternative would leave the question’s specific implementation unresolved.

D:

REST requests require the appropriate management service exposure and reachability beyond the presence of SSH. The offered alternative applies that mechanism: Verify HTTPS server availability and REST access on the intended management VRF with authorized client connectivity. The reported facts point to a different controlling condition: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. The alternative does not directly settle the required implementation.

Question 438

At the Highbridge transport facility, an important fiber link remains up but its optical receive power steadily approaches the transceiver threshold. Which underlying issue most directly explains this situation?

  1. User experience can degrade in identity services even with healthy switching and routing
  2. REST requests require the appropriate management service exposure and reachability beyond the presence of SSH
  3. Backups co-located with the failed site cannot support restoration after a regional disaster
  4. A link can appear operational until optical margins deteriorate enough to cause intermittent failure

Explanation

Correct Answer

D:

The problem stems from the fact that a link can appear operational until optical margins deteriorate enough to cause intermittent failure. A correct solution would trend receive power and temperature against supported optics specifications and schedule proactive remediation and check that an early warning triggers before the test link reaches the specified optical threshold. This result addresses the stated challenge at the Highbridge transport facility.

Incorrect Answers

A:

The option states: User experience can degrade in identity services even with healthy switching and routing. By contrast, the current situation is governed by: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

B:

REST requests require the appropriate management service exposure and reachability beyond the presence of SSH. The present question instead depends on this mechanism: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. That difference matters for the requested root-cause explanation.

C:

backups co-located with the failed site cannot support restoration after a regional disaster, rather than merely a monitoring or presentation issue. The offered alternative applies that mechanism: Backups co-located with the failed site cannot support restoration after a regional disaster. The reported facts point to a different controlling condition: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. The alternative does not directly settle the required root-cause explanation.

Question 439

At the Highbridge transport facility, an important fiber link remains up but its optical receive power steadily approaches the transceiver threshold. What evidence would justify considering this concern addressed?

  1. A dashboard alert fires for a seeded sustained discard increase before an application outage
  2. The script completes read-only inventory checks against each approved test release
  3. A lab and pilot group complete the approved upgrade with route and VLAN health intact
  4. An early warning triggers before the test link reaches the specified optical threshold

Explanation

Correct Answer

D:

This is the relevant acceptance result: an early warning triggers before the test link reaches the specified optical threshold. It demonstrates the outcome of choosing to trend receive power and temperature against supported optics specifications and schedule proactive remediation. This result addresses the stated challenge at the Highbridge transport facility.

Incorrect Answers

A:

A dashboard alert fires for a seeded sustained discard increase before an application outage. This option is based on the following distinct technical behavior: binary link state can hide progressive congestion and packet-quality degradation. The present question instead depends on this mechanism: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. That difference matters for the requested acceptance evidence.

B:

aPI resource version availability can differ between AOS-CX software releases and platforms. The offered alternative applies that mechanism: The script completes read-only inventory checks against each approved test release. The reported facts point to a different controlling condition: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. The alternative does not directly settle the required acceptance evidence.

C:

A lab and pilot group complete the approved upgrade with route and VLAN health intact. Its technical scope is explained by: aging and inconsistent firmware creates security and interoperability risk across the fabric. In this question, the decisive issue is: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. That is why the offered option is not the most direct acceptance evidence.

Question 440

At the Highbridge transport facility, an important fiber link remains up but its optical receive power steadily approaches the transceiver threshold. How should the organization sustain the improvement?

  1. Alert on unauthorized spanning-tree root elections
  2. Review optic sensor history and replacement candidates monthly
  3. Audit backup completion and test recoverability each quarter
  4. Compare switches to the baseline after every change window

Explanation

Correct Answer

B:

For the Highbridge transport facility, this maintenance action preserves the fix: review optic sensor history and replacement candidates monthly. It should be revisited as the workload evolves.

Incorrect Answers

A:

frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. The offered alternative applies that mechanism: Alert on unauthorized spanning-tree root elections. The reported facts point to a different controlling condition: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. The alternative does not directly settle the required recurrence control.

C:

The option states: Audit backup completion and test recoverability each quarter. The source describes its associated mechanism as: a switch running configuration cannot be reconstructed reliably after hardware loss without an archived copy, rather than merely a monitoring or presentation issue. By contrast, the current situation is governed by: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. Choosing this alternative would leave the question’s specific recurrence control unresolved.

D:

Compare switches to the baseline after every change window. This option is based on the following distinct technical behavior: configuration drift increases security exposure and incident uncertainty between otherwise similar sites. The present question instead depends on this mechanism: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. That difference matters for the requested recurrence control.
