Question 480

At the Oakport public agency, IPTV clients report intermittent stream loss but administrators inspect only ordinary unicast route summaries. Which ongoing control best prevents this issue from recurring?

  1. Trend multicast membership and RPF failure counts
  2. Review NAE agent performance and false-alert rates quarterly
  3. Audit configuration changes against approved work orders monthly
  4. Keep platform migration mappings in backup runbooks

Explanation

Correct Answer

A:

The continuing safeguard is to trend multicast membership and RPF failure counts. It helps avoid the original condition: multicast delivery depends on its own control and forwarding tables in addition to unicast routing. This result addresses the stated challenge at the Oakport public agency.

Incorrect Answers

B:

Review NAE agent performance and false-alert rates quarterly. Its technical scope is explained by: it requires the team to review NAE agent performance and false-alert rates quarterly. In this question, the decisive issue is: multicast delivery depends on its own control and forwarding tables in addition to unicast routing, the required evidence must show that a monitored subscription test shows receiver memberships and source packets on the approved interface. That is why the offered option is not the most direct recurrence control.

C:

The option states: Audit configuration changes against approved work orders monthly. The source describes its associated mechanism as: uncontrolled edits remove traceability and may prevent rapid service restoration. By contrast, the current situation is governed by: multicast delivery depends on its own control and forwarding tables in addition to unicast routing, the required evidence must show that a monitored subscription test shows receiver memberships and source packets on the approved interface. Choosing this alternative would leave the question’s specific recurrence control unresolved.

D:

Keep platform migration mappings in backup runbooks. This option is based on the following distinct technical behavior: 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 present question instead depends on this mechanism: multicast delivery depends on its own control and forwarding tables in addition to unicast routing, the required evidence must show that a monitored subscription test shows receiver memberships and source packets on the approved interface. That difference matters for the requested recurrence control.

Question 481

At the Claremont telecommunications company, an enterprise delays uplink replacement because current average traffic is low despite repeated peak congestion. Which implementation choice best addresses the situation?

  1. Use busy-hour utilization percentile trends growth forecasting and queue drops for capacity planning
  2. Inspect neighbor event history adjacency uptime and relevant interface logs instead of only the routing table
  3. Manage a reviewed golden configuration baseline with documented per-site exceptions
  4. Create scheduled versioned configuration backups with protected storage and periodic restore checks

Explanation

Correct Answer

A:

This solution addresses the stated limitation: average throughput obscures repeated peaks and does not establish adequate burst headroom. Implementing it means the team should use busy-hour utilization percentile trends growth forecasting and queue drops for capacity planning, then verify that a forecast predicts the upgrade threshold before expected user and application growth. This result addresses the stated challenge at the Claremont telecommunications company.

Incorrect Answers

B:

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: 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 choice would not address that particular implementation directly.

C:

Manage a reviewed golden configuration baseline with documented per-site exceptions. 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: 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. That difference matters for the requested implementation.

D:

a switch running configuration cannot be reconstructed reliably after hardware loss without an archived copy, rather than merely a monitoring or presentation issue. The offered alternative applies that mechanism: Create scheduled versioned configuration backups with protected storage and periodic restore checks. The reported facts point to a different controlling condition: 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 alternative does not directly settle the required implementation.

Question 482

At the Claremont telecommunications company, an enterprise delays uplink replacement because current average traffic is low despite repeated peak congestion. What risk should the team identify as the primary issue?

  1. A degraded inter-switch link can compromise multi-chassis resilience even while user traffic works
  2. Average throughput obscures repeated peaks and does not establish adequate burst headroom
  3. A switch running configuration cannot be reconstructed reliably after hardware loss without an archived copy
  4. API resource version availability can differ between AOS-CX software releases and platforms

Explanation

Correct Answer

B:

This identifies the root issue: average throughput obscures repeated peaks and does not establish adequate burst headroom. At the Claremont telecommunications company, the team should therefore use busy-hour utilization percentile trends growth forecasting and queue drops for capacity planning.

Incorrect Answers

A:

The option states: A degraded inter-switch link can compromise multi-chassis resilience even while user traffic works. By contrast, the current situation is governed by: average throughput obscures repeated peaks and does not establish adequate burst headroom. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

C:

a switch running configuration cannot be reconstructed reliably after hardware loss without an archived copy, rather than merely a monitoring or presentation issue. The offered alternative applies that mechanism: A switch running configuration cannot be reconstructed reliably after hardware loss without an archived copy. The reported facts point to a different controlling condition: average throughput obscures repeated peaks and does not establish adequate burst headroom. 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: average throughput obscures repeated peaks and does not establish adequate burst headroom. That is why the offered option is not the most direct root-cause explanation.

Question 483

At the Claremont telecommunications company, an enterprise delays uplink replacement because current average traffic is low despite repeated peak congestion. What is the strongest acceptance test for this change?

  1. A forecast predicts the upgrade threshold before expected user and application growth
  2. An OSPF reset fixture generates the correct neighbor stability alert
  3. A replacement lab device restores the required network state from the latest approved backup
  4. Unauthorized test users cannot retrieve the archived configuration and authorized restores succeed

Explanation

Correct Answer

A:

Because 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. A healthy endpoint status alone is insufficient. This result addresses the stated challenge at the Claremont telecommunications company.

Incorrect Answers

B:

An OSPF reset fixture generates the correct neighbor stability alert. The reported problem is governed by this different mechanism: 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 choice would not address that particular acceptance evidence directly.

C:

A replacement lab device restores the required network state from the latest approved backup. Its technical scope is explained by: a switch running configuration cannot be reconstructed reliably after hardware loss without an archived copy, rather than merely a monitoring or presentation issue. In this question, the decisive issue is: 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. That is why the offered option is not the most direct acceptance evidence.

D:

The option states: Unauthorized test users cannot retrieve the archived configuration and authorized restores succeed. The source describes its associated mechanism as: configuration backups can expose operational credentials and topology even without device login, rather than merely a monitoring or presentation issue. By contrast, the current situation is governed by: 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. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 484

At the Claremont telecommunications company, an enterprise delays uplink replacement because current average traffic is low despite repeated peak congestion. Which setting or practice should be reviewed in future?

  1. Review capacity forecasts and procurement lead times each quarter
  2. Review flap counts and hello processing after network changes
  3. Audit VSX consistency after each distribution change
  4. Audit configuration changes against approved work orders monthly

Explanation

Correct Answer

A:

After implementation, the team should review capacity forecasts and procurement lead times each quarter as the appropriate recurring safeguard against the identified issue. This result addresses the stated challenge at the Claremont telecommunications company.

Incorrect Answers

B:

Review flap counts and hello processing after network changes. The reported problem is governed by this different mechanism: 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 choice would not address that particular recurrence control directly.

C:

The option states: Audit VSX consistency after each distribution change. 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: 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. Choosing this alternative would leave the question’s specific recurrence control unresolved.

D:

Audit configuration changes against approved work orders monthly. This option is based on the following distinct technical behavior: uncontrolled edits remove traceability and may prevent rapid service restoration. The present question instead depends on this mechanism: 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. That difference matters for the requested recurrence control.

Question 485

At the Redhaven software campus, an automation script breaks after firmware upgrades because it hardcodes an unsupported REST API endpoint version. Which corrective action best meets the requirement?

  1. Verify HTTPS server availability and REST access on the intended management VRF with authorized client connectivity
  2. Validate target model and software compatibility and transform unsupported commands before restoration
  3. Query the switch for supported REST API versions and use the appropriate supported version or latest path
  4. Inspect neighbor event history adjacency uptime and relevant interface logs instead of only the routing table

Explanation

Correct Answer

C:

The reported facts support this change rather than a general platform replacement. The team should query the switch for supported REST API versions and use the appropriate supported version or latest path because aPI resource version availability can differ between AOS-CX software releases and platforms. A suitable test confirms that the script completes read-only inventory checks against each approved test release. This result addresses the stated challenge at the Redhaven software campus.

Incorrect Answers

A:

Verify HTTPS server availability and REST access on the intended management VRF with authorized client connectivity. 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: aPI resource version availability can differ between AOS-CX software releases and platforms. That is why the offered option is not the most direct implementation.

B:

The option states: Validate target model and software compatibility and transform unsupported commands before restoration. The source describes its associated mechanism as: a backup from different hardware or release cannot be assumed directly reusable. By contrast, the current situation is governed by: aPI resource version availability can differ between AOS-CX software releases and platforms. Choosing this alternative would leave the question’s specific implementation unresolved.

D:

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: aPI resource version availability can differ between AOS-CX software releases and platforms. The offered choice would not address that particular implementation directly.

Question 486

At the Redhaven software campus, an automation script breaks after firmware upgrades because it hardcodes an unsupported REST API endpoint version. Which underlying issue most directly explains this situation?

  1. API resource version availability can differ between AOS-CX software releases and platforms
  2. REST sessions and tokens must be established and refreshed according to platform security requirements
  3. Software resource contention can delay control processes while hardware interfaces look healthy
  4. Configuration backups can expose operational credentials and topology even without device login

Explanation

Correct Answer

A:

The evidence indicates that aPI resource version availability can differ between AOS-CX software releases and platforms. The appropriate response is to query the switch for supported REST API versions and use the appropriate supported version or latest path and demonstrate that the script completes read-only inventory checks against each approved test release. This result addresses the stated challenge at the Redhaven software campus.

Incorrect Answers

B:

REST sessions and tokens must be established and refreshed according to platform security requirements. The reported problem is governed by this different mechanism: aPI resource version availability can differ between AOS-CX software releases and platforms. The offered choice would not address that particular root-cause explanation directly.

C:

it requires the team to track resource baselines and software version regressions. The offered alternative applies that mechanism: Software resource contention can delay control processes while hardware interfaces look healthy. The reported facts point to a different controlling condition: aPI resource version availability can differ between AOS-CX software releases and platforms. The alternative does not directly settle the required root-cause explanation.

D:

Configuration backups can expose operational credentials and topology even without device login. Its technical scope is explained by: configuration backups can expose operational credentials and topology even without device login, rather than merely a monitoring or presentation issue. In this question, the decisive issue is: aPI resource version availability can differ between AOS-CX software releases and platforms. That is why the offered option is not the most direct root-cause explanation.

Question 487

At the Redhaven software campus, an automation script breaks after firmware upgrades because it hardcodes an unsupported REST API endpoint version. What evidence would justify considering this concern addressed?

  1. A test job authenticates modifies only the permitted resource and terminates its session
  2. A peer-by-peer comparison shows approved consistent ACLs and member failover
  3. The script completes read-only inventory checks against each approved test release
  4. A pilot site receives only the intended changes and other sites retain baseline service

Explanation

Correct Answer

C:

At the Redhaven software campus, evidence that the script completes read-only inventory checks against each approved test release directly validates the correction, instead of testing a neighboring service.

Incorrect Answers

A:

A test job authenticates modifies only the permitted resource and terminates its session. The reported problem is governed by this different mechanism: aPI resource version availability can differ between AOS-CX software releases and platforms. The offered choice would not address that particular acceptance evidence directly.

B:

peer configuration drift can produce different forwarding and security outcomes after failover. The offered alternative applies that mechanism: A peer-by-peer comparison shows approved consistent ACLs and member failover. The reported facts point to a different controlling condition: aPI resource version availability can differ between AOS-CX software releases and platforms. 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: aPI resource version availability can differ between AOS-CX software releases and platforms. Choosing this alternative would leave the question’s specific acceptance evidence unresolved.

Question 488

At the Redhaven software campus, an automation script breaks after firmware upgrades because it hardcodes an unsupported REST API endpoint version. How should the organization sustain the improvement?

  1. Audit HTTPS management reachability and VRF restrictions routinely
  2. Audit configuration changes against approved work orders monthly
  3. Check cooling and hardware alarms during routine site walks
  4. Revalidate API versions and schemas after firmware changes

Explanation

Correct Answer

D:

The needed prevention is to revalidate API versions and schemas after firmware changes. It directly sustains the original change to query the switch for supported REST API versions and use the appropriate supported version or latest path. This result addresses the stated challenge at the Redhaven software campus.

Incorrect Answers

A:

REST requests require the appropriate management service exposure and reachability beyond the presence of SSH. The offered alternative applies that mechanism: Audit HTTPS management reachability and VRF restrictions routinely. The reported facts point to a different controlling condition: aPI resource version availability can differ between AOS-CX software releases and platforms. The alternative does not directly settle the required recurrence control.

B:

Audit configuration changes against approved work orders monthly. Its technical scope is explained by: uncontrolled edits remove traceability and may prevent rapid service restoration. In this question, the decisive issue is: aPI resource version availability can differ between AOS-CX software releases and platforms. That is why the offered option is not the most direct recurrence control.

C:

The option states: Check cooling and hardware alarms during routine site walks. The source describes its associated mechanism as: thermal faults can destabilize forwarding independent of network traffic congestion. By contrast, the current situation is governed by: aPI resource version availability can differ between AOS-CX software releases and platforms. Choosing this alternative would leave the question’s specific recurrence control unresolved.

Question 489

At the Dunbridge research organization, a controller cannot reach AOS-CX REST endpoints although SSH works over the dedicated management network. Which approach best resolves the described issue?

  1. Use supported AOS-CX REST login session cookie CSRF token handling and clean logout for the target release
  2. Create scheduled versioned configuration backups with protected storage and periodic restore checks
  3. Version group templates and evaluate inheritance impact against pilot devices before wider push
  4. Verify HTTPS server availability and REST access on the intended management VRF with authorized client connectivity

Explanation

Correct Answer

D:

Verify HTTPS server availability and REST access on the intended management VRF with authorized client connectivity is the best response because REST requests require the appropriate management service exposure and reachability beyond the presence of SSH. A focused validation would establish that an approved API client authenticates over the management VRF while unauthorized sources fail. This result addresses the stated challenge at the Dunbridge research organization.

Incorrect Answers

A:

Use supported AOS-CX REST login session cookie CSRF token handling and clean logout for the target release. The reported problem is governed by this different mechanism: REST requests require the appropriate management service exposure and reachability beyond the presence of SSH. The offered choice would not address that particular root-cause explanation directly.

B:

The option states: Create scheduled versioned configuration backups with protected storage and periodic restore checks. 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: REST requests require the appropriate management service exposure and reachability beyond the presence of SSH. Choosing this alternative would leave the question’s specific root-cause explanation unresolved.

C:

Version group templates and evaluate inheritance impact against pilot devices before wider push. This option is based on the following distinct technical behavior: a global or group template change may affect more devices than the operator expects. The present question instead depends on this mechanism: REST requests require the appropriate management service exposure and reachability beyond the presence of SSH. That difference matters for the requested root-cause explanation.

Question 490

At the Dunbridge research organization, a controller cannot reach AOS-CX REST endpoints although SSH works over the dedicated management network. Which explanation best accounts for the concern?

  1. REST sessions and tokens must be established and refreshed according to platform security requirements
  2. Uncontrolled edits remove traceability and may prevent rapid service restoration
  3. Poor ownership records delay approvals and root cause investigation after changes
  4. REST requests require the appropriate management service exposure and reachability beyond the presence of SSH

Explanation

Correct Answer

D:

This identifies the root issue: REST requests require the appropriate management service exposure and reachability beyond the presence of SSH. At the Dunbridge research organization, the team should therefore verify HTTPS server availability and REST access on the intended management VRF with authorized client connectivity.

Incorrect Answers

A:

REST sessions and tokens must be established and refreshed according to platform security requirements. The reported problem is governed by this different mechanism: REST requests require the appropriate management service exposure and reachability beyond the presence of SSH.

B:

Uncontrolled edits remove traceability and may prevent rapid service restoration. The present question instead depends on this mechanism: REST requests require the appropriate management service exposure and reachability beyond the presence of SSH. That difference matters for the requested root-cause explanation.
