Cisco 350-401 Practice Test 57

Question 560

A business application uses UDP voice flows and a manager measures only ping latency to infer voice quality. The incident evidence is: Voice breaks up while ICMP round-trip latency remains acceptable. Which targeted configuration or design change best addresses the failure?

  1. Use a supported IPSLA UDP-jitter operation when the platform supports the intended test to measure jitter/packet loss.
  2. Associate the supported IPSLA reachability operation with object tracking and the conditional route.
  3. Attach the correct flow monitor to the intended ingress or egress direction supported by the platform.
  4. Configure an IPSLA ICMP echo operation and a schedule with the intended source interface and target.

Explanation

Correct Answer

A:

The required correction is: Use a supported IPSLA UDP-jitter operation when the platform supports the intended test to measure jitter/packet loss. The underlying failure mechanism is: Basic ICMP RTT does not measure the interpacket-delay variation and loss affecting voice quality. Verify success by carrying out this direct test: compare UDP-jitter output under controlled impaired links against basic ICMP RTT.

Incorrect Answers

B:

Associate the supported IPSLA reachability operation with object tracking and the conditional route would not meet the need for a supported IPSLA UDP-jitter operation when the platform supports the intended test to measure jitter/packet loss.

C:

Attaching the correct flow monitor to the intended ingress or egress direction supported by the platform would not meet the need for a supported IPSLA UDP-jitter operation when the platform supports the intended test to measure jitter/packet loss.

D:

Configuring an IPSLA ICMP echo operation and a schedule with the intended source interface and target would not meet the need for a supported IPSLA UDP-jitter operation when the platform supports the intended test to measure jitter/packet loss.

Question 561

A business application uses UDP voice flows and a manager measures only ping latency to infer voice quality. The proposed remedy is: Use a supported IPSLA UDP-jitter operation when the platform supports the intended test to measure jitter/packet loss. Which observation would most directly confirm that remedy works as intended?

  1. Compare UDP-jitter output under controlled impaired links against basic ICMP RTT.
  2. Inspect IPSLA success, RTT and last return code over controlled test intervals.
  3. Disable the target path and verify track state causes correct static-route failover.
  4. Observe flow cache counters for traffic in the actual direction and match collector records.

Explanation

Correct Answer

A:

The decisive acceptance observation is: Compare UDP-jitter output under controlled impaired links against basic ICMP RTT. This tests the working mechanism, while the original incident was: voice breaks up while ICMP round-trip latency remains acceptable.

Incorrect Answers

B:

This test measures a different behavior: Inspect IPSLA success, RTT and last return code over controlled test intervals. It does not establish the target outcome. For the documented fault, the direct acceptance test is: compare UDP-jitter output under controlled impaired links against basic ICMP RTT.

C:

This test measures a different behavior: Disable the target path and verify track state causes correct static-route failover. It does not establish the target outcome. For the documented fault, the direct acceptance test is: compare UDP-jitter output under controlled impaired links against basic ICMP RTT.

D:

This test measures a different behavior: Observe flow cache counters for traffic in the actual direction and match collector records. It does not establish the target outcome. For the documented fault, the direct acceptance test is: compare UDP-jitter output under controlled impaired links against basic ICMP RTT.

Question 562

A business application uses UDP voice flows and a manager measures only ping latency to infer voice quality. During troubleshooting: Voice breaks up while ICMP round-trip latency remains acceptable. Which underlying cause best explains the recorded behavior?

  1. The IPSLA operation was not scheduled or started.
  2. Basic ICMP RTT does not measure the interpacket-delay variation and loss affecting voice quality.
  3. The monitor is attached in the wrong traffic direction/interface for the tested flows.
  4. The route has no operative track dependency tied to IPSLA status.

Explanation

Correct Answer

B:

The actual technical cause is: Basic ICMP RTT does not measure the interpacket-delay variation and loss affecting voice quality. It specifically explains the observation: voice breaks up while ICMP round-trip latency remains acceptable. The correcting configuration is: use a supported IPSLA UDP-jitter operation when the platform supports the intended test to measure jitter/packet loss.

Incorrect Answers

A:

That diagnosis is supported by a different symptom: The monitoring dashboard shows no probes after the IPSLA operation was configured. Here the recorded observation is: voice breaks up while ICMP round-trip latency remains acceptable. The applicable cause is: basic ICMP RTT does not measure the interpacket-delay variation and loss affecting voice quality.

C:

That diagnosis is supported by a different symptom: Telemetry remains empty during an outbound-only test despite healthy exporter sessions. Here the recorded observation is: voice breaks up while ICMP round-trip latency remains acceptable. The applicable cause is: basic ICMP RTT does not measure the interpacket-delay variation and loss affecting voice quality.

D:

That diagnosis is supported by a different symptom: The primary static route remains in the RIB after its monitored endpoint stops responding. Here the recorded observation is: voice breaks up while ICMP round-trip latency remains acceptable. The applicable cause is: basic ICMP RTT does not measure the interpacket-delay variation and loss affecting voice quality.

Question 563

A business application uses UDP voice flows and a manager measures only ping latency to infer voice quality. The initial change is: Use a supported IPSLA UDP-jitter operation when the platform supports the intended test to measure jitter/packet loss. Which continuing control most directly prevents a recurrence of the documented problem: Voice breaks up while ICMP round-trip latency remains acceptable.

  1. Include service-protocol checks and relevant source/destination/port details in diagnostic evidence.
  2. Audit operation schedules and reaction thresholds when deploying synthetic monitoring.
  3. Validate backup-route reachability and avoid tracking only a local interface when remote path health matters.
  4. Track UDP-specific jitter and packet-loss thresholds separately from generic ping availability.

Explanation

Correct Answer

D:

The continuing protective control is: Track UDP-specific jitter and packet-loss thresholds separately from generic ping availability. This addresses the underlying failure mechanism: basic ICMP RTT does not measure the interpacket-delay variation and loss affecting voice quality. The corresponding operational check is: compare UDP-jitter output under controlled impaired links against basic ICMP RTT.

Incorrect Answers

A:

That control reduces a separate risk: ICMP echo reachability does not prove that TCP443 is allowed through middleboxes. For the described design, the recurring risk arises from: basic ICMP RTT does not measure the interpacket-delay variation and loss affecting voice quality. The specific required safeguard is: track UDP-specific jitter and packet-loss thresholds separately from generic ping availability.

B:

That control reduces a separate risk: The IPSLA operation was not scheduled or started. For the described design, the recurring risk arises from: basic ICMP RTT does not measure the interpacket-delay variation and loss affecting voice quality. The specific required safeguard is: track UDP-specific jitter and packet-loss thresholds separately from generic ping availability.

C:

That control reduces a separate risk: The route has no operative track dependency tied to IPSLA status. For the described design, the recurring risk arises from: basic ICMP RTT does not measure the interpacket-delay variation and loss affecting voice quality. The specific required safeguard is: track UDP-specific jitter and packet-loss thresholds separately from generic ping availability.

Question 564

A campus operations team wants Cisco Catalyst Center Assurance to correlate network-device health and client path experience instead of running manual show commands on every node. The incident evidence is: An administrator assumes inventory registration alone automatically populates all assurance metrics without telemetry collection. Which targeted configuration or design change best addresses the failure?

  1. Use supported Catalyst Center template/provisioning workflow with target device scope and staged validation.
  2. Use supported Cisco Catalyst Center assurance telemetry, inventory and path trace workflows.
  3. Use interface counters, flow/trace data and narrowly bounded tests instead of continuous invasive debugging.
  4. Correlate AI insights with actual device telemetry, client timeline and path tests before remediation.

Explanation

Correct Answer

B:

The required correction is: Use supported Cisco Catalyst Center assurance telemetry, inventory and path trace workflows. The underlying failure mechanism is: Required device integration, credentials or telemetry sources for Assurance are incomplete. Verify success by carrying out this direct test: inspect an affected client path/health issue and drill into specific device/interface evidence.

Incorrect Answers

A:

Using supported Catalyst Center template/provisioning workflow with target device scope and staged validation would not meet the need for supported Cisco Catalyst Center assurance telemetry, inventory and path trace workflows.

C:

Using interface counters, flow/trace data and narrowly bounded tests would not meet the need for supported Cisco Catalyst Center assurance telemetry, inventory and path trace workflows.

D:

Correlating AI insights with actual device telemetry, client timeline and path tests would not meet the need for supported Cisco Catalyst Center assurance telemetry, inventory and path trace workflows.

Question 565

A campus operations team wants Cisco Catalyst Center Assurance to correlate network-device health and client path experience instead of running manual show commands on every node.

  1. Inspect an affected client path/health issue and drill into specific device/interface evidence.
  2. Compare the suggested fault time to measured interface errors and packet loss on affected clients.
  3. Compare low-overhead telemetry before, during and after the event at the same time scale.
  4. Preview intended differences and verify running configuration and compliance on a pilot device.

Explanation

Correct Answer

A:

The decisive acceptance observation is: Inspect an affected client path/health issue and drill into specific device/interface evidence. This tests the working mechanism, while the original incident was: an administrator assumes inventory registration alone automatically populates all assurance metrics without telemetry collection.

Incorrect Answers

B:

This test measures a different behavior: Compare the suggested fault time to measured interface errors and packet loss on affected clients. It does not establish the target outcome.

Question 566

A campus operations team wants Cisco Catalyst Center Assurance to correlate network-device health and client path experience instead of running manual show commands on every node. During troubleshooting: An administrator assumes inventory registration alone automatically populates all assurance metrics without telemetry collection. Which underlying cause best explains the recorded behavior?

  1. The diagnostic itself adds CPU and logging overhead that changes production behavior.
  2. A model-generated insight was treated as definitive without corroborating observations.
  3. The change was drafted but device/site scope and deployment were not completed.
  4. Required device integration, credentials or telemetry sources for Assurance are incomplete.

Explanation

Correct Answer

D:

The actual technical cause is: Required device integration, credentials or telemetry sources for Assurance are incomplete. It specifically explains the observation: an administrator assumes inventory registration alone automatically populates all assurance metrics without telemetry collection. The correcting configuration is: use supported Cisco Catalyst Center assurance telemetry, inventory and path trace workflows.

Incorrect Answers

A:

That diagnosis is supported by a different symptom: A high-rate debug makes a forwarding problem appear worse by starving the control plane. Here the recorded observation is: an administrator assumes inventory registration alone automatically populates all assurance metrics without telemetry collection. The applicable cause is: required device integration, credentials or telemetry sources for Assurance are incomplete.

B:

That diagnosis is supported by a different symptom: A team changes routing because an AI tile mentions congestion with no matching traffic evidence. Here the recorded observation is: an administrator assumes inventory registration alone automatically populates all assurance metrics without telemetry collection. The applicable cause is: required device integration, credentials or telemetry sources for Assurance are incomplete.

C:

That diagnosis is supported by a different symptom: Some switches keep old configuration because the template was not provisioned to their site inventory. Here the recorded observation is: an administrator assumes inventory registration alone automatically populates all assurance metrics without telemetry collection. The applicable cause is: required device integration, credentials or telemetry sources for Assurance are incomplete.

Question 567

A campus operations team wants Cisco Catalyst Center Assurance to correlate network-device health and client path experience instead of running manual show commands on every node. The initial change is: Use supported Cisco Catalyst Center assurance telemetry, inventory and path trace workflows. Which continuing control most directly prevents a recurrence of the documented problem: An administrator assumes inventory registration alone automatically populates all assurance metrics without telemetry collection.

  1. Establish a safe debug escalation process and baseline telemetry before intrusive tools.
  2. Monitor telemetry coverage and data freshness before basing incidents on health scores.
  3. Keep operator review and telemetry evidence alongside AI-assisted network recommendations.
  4. Apply change templates through reviewed sites and post-deployment compliance checks.
