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.

Question 441

At the Zephyrhaven regional hospital, a building periodically changes MSTP root bridge during normal operations and experiences short user traffic interruptions. Which approach best resolves the described issue?

  1. Correlate spanning-tree topology-change counters and root history to identify unexpected bridge transitions
  2. Trend receive power and temperature against supported optics specifications and schedule proactive remediation
  3. Create scheduled versioned configuration backups with protected storage and periodic restore checks
  4. Store encrypted configuration recovery copies in an independent approved offsite repository

Explanation

Correct Answer

A:

The reported facts support this change rather than a general platform replacement. The team should correlate spanning-tree topology-change counters and root history to identify unexpected bridge transitions because frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. A suitable test confirms that a controlled bridge event is correlated with topology logs and the expected root is restored. This result addresses the stated challenge at the Zephyrhaven regional hospital.

Incorrect Answers

B:

The option states: Trend receive power and temperature against supported optics specifications and schedule proactive remediation. The source describes its associated mechanism as: a link can appear operational until optical margins deteriorate enough to cause intermittent failure. By contrast, the current situation is governed by: frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

C:

Create scheduled versioned configuration backups with protected storage and periodic restore checks. This option is based on the following distinct technical behavior: a switch running configuration cannot be reconstructed reliably after hardware loss without an archived copy, rather than merely a monitoring or presentation issue. The present question instead depends on this mechanism: frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. That difference matters for the requested root-cause explanation.

D:

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: Store encrypted configuration recovery copies in an independent approved offsite repository. The reported facts point to a different controlling condition: frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. The alternative does not directly settle the required root-cause explanation.

Question 442

At the Zephyrhaven regional hospital, a building periodically changes MSTP root bridge during normal operations and experiences short user traffic interruptions. Which explanation best accounts for the concern?

  1. An alert without appropriate duration or threshold generates noise rather than useful incident signals
  2. Frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails
  3. Backups co-located with the failed site cannot support restoration after a regional disaster
  4. Configuration drift increases security exposure and incident uncertainty between otherwise similar sites

Explanation

Correct Answer

B:

The problem stems from the fact that frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. A correct solution would correlate spanning-tree topology-change counters and root history to identify unexpected bridge transitions and check that a controlled bridge event is correlated with topology logs and the expected root is restored. This result addresses the stated challenge at the Zephyrhaven regional hospital.

Incorrect Answers

A:

The option states: An alert without appropriate duration or threshold generates noise rather than useful incident signals. The source describes its associated mechanism as: an alert without appropriate duration or threshold generates noise rather than useful incident signals, rather than merely a monitoring or presentation issue. By contrast, the current situation is governed by: frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

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: frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. The alternative does not directly settle the required root-cause explanation.

D:

Configuration drift increases security exposure and incident uncertainty between otherwise similar sites. In this question, the decisive issue is: frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. That is why the offered option is not the most direct root-cause explanation.

Question 443

At the Zephyrhaven regional hospital, a building periodically changes MSTP root bridge during normal operations and experiences short user traffic interruptions. Which test result best shows the requirement is met?

  1. An OSPF reset fixture generates the correct neighbor stability alert
  2. A controlled bridge event is correlated with topology logs and the expected root is restored
  3. An approved API client authenticates over the management VRF while unauthorized sources fail
  4. The script completes read-only inventory checks against each approved test release

Explanation

Correct Answer

B:

This is the relevant acceptance result: a controlled bridge event is correlated with topology logs and the expected root is restored. It demonstrates the outcome of choosing to correlate spanning-tree topology-change counters and root history to identify unexpected bridge transitions. This result addresses the stated challenge at the Zephyrhaven regional hospital.

Incorrect Answers

A:

An OSPF reset fixture generates the correct neighbor stability alert. The reported problem is governed by this different mechanism: frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. The offered choice would not address that particular acceptance evidence directly.

C:

An approved API client authenticates over the management VRF while unauthorized sources fail. Its technical scope is explained by: REST requests require the appropriate management service exposure and reachability beyond the presence of SSH. In this question, the decisive issue is: frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. That is why the offered option is not the most direct acceptance evidence.

D:

The option states: The script completes read-only inventory checks against each approved test release. 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: frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 444

At the Zephyrhaven regional hospital, a building periodically changes MSTP root bridge during normal operations and experiences short user traffic interruptions. Which ongoing control best prevents this issue from recurring?

  1. Track ISL capacity peer events and redundancy targets
  2. Alert on unauthorized spanning-tree root elections
  3. Keep platform migration mappings in backup runbooks
  4. Audit backup completion and test recoverability each quarter

Explanation

Correct Answer

B:

The needed prevention is to alert on unauthorized spanning-tree root elections. It directly sustains the original change to correlate spanning-tree topology-change counters and root history to identify unexpected bridge transitions. This result addresses the stated challenge at the Zephyrhaven regional hospital.

Incorrect Answers

A:

it requires the team to track ISL capacity peer events and redundancy targets. The offered alternative applies that mechanism: Track ISL capacity peer events and redundancy targets. The reported facts point to a different controlling condition: frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. The alternative does not directly settle the required recurrence control.

C:

The option states: Keep platform migration mappings in backup runbooks. The source describes its associated mechanism as: 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. By contrast, the current situation is governed by: frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. Choosing this alternative would leave the question’s specific recurrence control unresolved.

D:

Audit backup completion and test recoverability each quarter. This option is based on the following distinct technical behavior: a switch running configuration cannot be reconstructed reliably after hardware loss without an archived copy, rather than merely a monitoring or presentation issue. The present question instead depends on this mechanism: frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. That difference matters for the requested recurrence control.

Question 445

At the Ivystone technical college, a four-port core LAG loses two members but its logical interface remains up and alerts stay green. Which implementation choice best addresses the situation?

  1. Trend interface discards error counters and utilization to select the appropriate remediation threshold
  2. Measure active member count and bundle capacity rather than only logical interface availability
  3. Verify HTTPS server availability and REST access on the intended management VRF with authorized client connectivity
  4. Version group templates and evaluate inheritance impact against pilot devices before wider push

Explanation

Correct Answer

B:

Measure active member count and bundle capacity rather than only logical interface availability is the best response because a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state. A focused validation would establish that the monitor detects a removed member and reports reduced aggregate capacity. This result addresses the stated challenge at the Ivystone technical college.

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 partially degraded aggregate can silently lose redundancy and throughput while reporting operational state. That is why the offered option is not the most direct implementation.

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: a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state. That difference matters for the requested implementation.

D:

a global or group template change may affect more devices than the operator expects. The offered alternative applies that mechanism: Version group templates and evaluate inheritance impact against pilot devices before wider push. The reported facts point to a different controlling condition: a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state. The alternative does not directly settle the required implementation.

Question 446

At the Ivystone technical college, a four-port core LAG loses two members but its logical interface remains up and alerts stay green. What risk should the team identify as the primary issue?

  1. A partially degraded aggregate can silently lose redundancy and throughput while reporting operational state
  2. User experience can degrade in identity services even with healthy switching and routing
  3. Repeated blind writes can create drift errors and difficult rollback even if the first execution succeeds
  4. API resource version availability can differ between AOS-CX software releases and platforms

Explanation

Correct Answer

A:

The situation shows that a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state, rather than merely a monitoring or presentation issue. Remediation is to measure active member count and bundle capacity rather than only logical interface availability. This result addresses the stated challenge at the Ivystone technical college.

Incorrect Answers

B:

User experience can degrade in identity services even with healthy switching and routing. The present question instead depends on this mechanism: a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state, rather than merely a monitoring or presentation issue. That difference matters for the requested root-cause explanation.

C:

The offered alternative states: Repeated blind writes can create drift errors and difficult rollback even if the first execution succeeds. The reported facts point to a different controlling condition: a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state, rather than merely a monitoring or presentation issue. The alternative does not directly settle the required root-cause explanation.

D:

API resource version availability can differ between AOS-CX software releases and platforms. In this question, the decisive issue is: a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state, rather than merely a monitoring or presentation issue. That is why the offered option is not the most direct root-cause explanation.

Question 447

At the Ivystone technical college, a four-port core LAG loses two members but its logical interface remains up and alerts stay green. What is the strongest acceptance test for this change?

  1. A controlled bridge event is correlated with topology logs and the expected root is restored
  2. A test restore identifies unsupported features and re-establishes intended forwarding
  3. The monitor detects a removed member and reports reduced aggregate capacity
  4. Running the automation twice yields no additional unauthorized configuration change

Explanation

Correct Answer

C:

This tests the real business behavior: the monitor detects a removed member and reports reduced aggregate capacity. It specifically checks whether the risk that a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state has been reduced. This result addresses the stated challenge at the Ivystone technical college.

Incorrect Answers

A:

A controlled bridge event is correlated with topology logs and the expected root is restored. This option is based on the following distinct technical behavior: frequent root movement can cause temporary forwarding reconvergence even when no interface permanently fails. The present question instead depends on this mechanism: a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state, rather than merely a monitoring or presentation issue. 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: a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state, rather than merely a monitoring or presentation issue. The alternative does not directly settle the required acceptance evidence.

D:

The option states: Running the automation twice yields no additional unauthorized configuration change. The source describes its associated mechanism as: repeated blind writes can create drift errors and difficult rollback even if the first execution succeeds. By contrast, the current situation is governed by: a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state, rather than merely a monitoring or presentation issue. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 448

At the Ivystone technical college, a four-port core LAG loses two members but its logical interface remains up and alerts stay green. Which setting or practice should be reviewed in future?

  1. Alert on unauthorized spanning-tree root elections
  2. Review vendor security advisories and supported release trains regularly
  3. Review LAG resiliency and partner status during maintenance
  4. Review credential handling token expiry and audit logs during automation updates

Explanation

Correct Answer

C:

The team should review LAG resiliency and partner status during maintenance. That recurring practice targets the same weakness, namely that a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state. This result addresses the stated challenge at the Ivystone technical college.

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 partially degraded aggregate can silently lose redundancy and throughput while reporting operational state, rather than merely a monitoring or presentation issue. The alternative does not directly settle the required recurrence control.

B:

Review vendor security advisories and supported release trains regularly. 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 partially degraded aggregate can silently lose redundancy and throughput while reporting operational state, rather than merely a monitoring or presentation issue. That is why the offered option is not the most direct recurrence control.

D:

Review credential handling token expiry and audit logs during automation updates. The reported problem is governed by this different mechanism: a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state, rather than merely a monitoring or presentation issue. The offered choice would not address that particular recurrence control directly.

Question 449

At the Westhaven public agency, a switch shows routes currently installed but OSPF neighbors have been repeatedly resetting over the past hour. Which corrective action best meets the requirement?

  1. Measure active member count and bundle capacity rather than only logical interface availability
  2. Validate target model and software compatibility and transform unsupported commands before restoration
  3. Use supported AOS-CX REST login session cookie CSRF token handling and clean logout for the target release
  4. Inspect neighbor event history adjacency uptime and relevant interface logs instead of only the routing table

Explanation

Correct Answer

D:

For the Westhaven public agency, the appropriate correction is to inspect neighbor event history adjacency uptime and relevant interface logs instead of only the routing table. The decisive reason is that snapshot route presence can conceal unstable sessions and transient packet loss; acceptance evidence is that an OSPF reset fixture generates the correct neighbor stability alert.

Incorrect Answers

A:

Measure active member count and bundle capacity rather than only logical interface availability. This option operates on the following technical behavior: a partially degraded aggregate can silently lose redundancy and throughput while reporting operational state. The source question instead asks about the control represented by: Inspect neighbor event history adjacency uptime and relevant interface logs instead of only the routing table. That distinction must be resolved for the requested implementation.

B:

Validate target model and software compatibility and transform unsupported commands before restoration. This option operates on the following technical behavior: a backup from different hardware or release cannot be assumed directly reusable. The source question instead asks about the control represented by: Inspect neighbor event history adjacency uptime and relevant interface logs instead of only the routing table. That distinction must be resolved for the requested implementation.

C:

AOS-CX REST API session and CSRF handling matters for authenticated automation requests. The current issue is unstable OSPF adjacencies: a routing-table snapshot may contain installed routes while neighbor resets continue. Neighbor history, uptime and interface logs reveal the repeated resets; REST login behavior does not establish OSPF stability.

Question 450

At the Westhaven public agency, a switch shows routes currently installed but OSPF neighbors have been repeatedly resetting over the past hour. Which underlying issue most directly explains this situation?

  1. A link can appear operational until optical margins deteriorate enough to cause intermittent failure
  2. Snapshot route presence can conceal unstable sessions and transient packet loss
  3. Backups co-located with the failed site cannot support restoration after a regional disaster
  4. Configuration drift increases security exposure and incident uncertainty between otherwise similar sites

Explanation

Correct Answer

B:

The architectural weakness is that snapshot route presence can conceal unstable sessions and transient packet loss. It can be addressed through the controlled change to inspect neighbor event history adjacency uptime and relevant interface logs instead of only the routing table. This result addresses the stated challenge at the Westhaven public agency.

Incorrect Answers

A:

A link can appear operational until optical margins deteriorate enough to cause intermittent failure. This option operates on the following technical behavior: a link can appear operational until optical margins deteriorate enough to cause intermittent failure.
