Question 370

At the Ironwood training campus, fault records from R-IRN-RT1 and R-CLR-RT2 arrive at the same syslog collector but their timestamps differ by minutes, hiding causal order. Which underlying technical condition best accounts for this evidence?

  1. Unsynchronized device time makes otherwise collected logs unreliable for cross-device event correlation.
  2. Event-only syslog messages do not provide the periodic operational counter series requested.
  3. Duplicate-address conflicts are withholding otherwise available pool addresses from assignment.
  4. Client DHCP broadcasts are not forwarded across the router to the remote DHCP service.

Explanation

Correct Answer

A:

The evidence at the Ironwood training campus supports this condition: Unsynchronized device time makes otherwise collected logs unreliable for cross-device event correlation. The associated fix is: Synchronize network device clocks using approved time sources and include usable syslog timestamps.

Incorrect Answers

B:

This diagnoses a different mechanism: Event-only syslog messages do not provide the periodic operational counter series requested. The reported symptom at the Ironwood training campus instead concerns syslog timestamp correlation.

C:

That diagnosis belongs to dhcp declined conflicts, while the observation at the Ironwood training campus points to syslog timestamp correlation.

D:

The observation at the Ironwood training campus does not point to ipv4 dhcp relay for remote server; it points to a different condition. Unsynchronized device time makes otherwise collected logs unreliable for cross-device event correlation.

Question 371

At the Hillcrest research lab, a remote syslog collector receives critical events but not informational interface-change records from R-HCR-RT1. Which underlying technical condition best accounts for this evidence?

  1. Hosts are not signaled to use DHCPv6 for auxiliary information despite having SLAAC addresses.
  2. Unrestricted debug processing is consuming resources that the routing device needs for production forwarding and control.
  3. The relay function required to forward DHCPv6 messages to a remote server is absent or misdirected.
  4. The remote logging level filters less-severe events before they are forwarded.

Explanation

Correct Answer

D:

This diagnosis fits the symptoms at the Hillcrest research lab. The remote logging level filters less-severe events before they are forwarded. The remedial action is: Set the remote logging severity threshold to include the events needed by operations without overloading the collector.

Incorrect Answers

A:

That diagnosis belongs to dhcpv6 stateless information request, while the observation at the Hillcrest research lab points to syslog severity threshold.

B:

The observation at the Hillcrest research lab does not point to conditional debug and router load; it points to a different condition. The remote logging level filters less-severe events before they are forwarded.

C:

This diagnoses a different mechanism: The relay function required to forward DHCPv6 messages to a remote server is absent or misdirected. The reported symptom at the Hillcrest research lab instead concerns syslog severity threshold.

Question 372

  2. Client DHCP broadcasts are not forwarded across the router to the remote DHCP service.
  3. The remote logging level filters less-severe events before they are forwarded.
  4. Unsynchronized device time makes otherwise collected logs unreliable for cross-device event correlation.

Explanation

This diagnoses a different mechanism: Unsynchronized device time makes otherwise collected logs unreliable for cross-device event correlation. The reported symptom at the Northport logistics site instead concerns syslog severity threshold.

Question 373

At the Elmfield engineering office, a technician enables unrestricted high-volume routing debug on R-ELM-EDGE1, sharply increasing CPU load during a customer incident. Which underlying technical condition best accounts for this evidence?

  1. Unsynchronized device time makes otherwise collected logs unreliable for cross-device event correlation.
  2. Unrestricted debug processing is consuming resources that the routing device needs for production forwarding and control.
  3. Duplicate-address conflicts are withholding otherwise available pool addresses from assignment.
  4. The remote logging level filters less-severe events before they are forwarded.

Explanation

Correct Answer

B:

Unrestricted debug processing is consuming resources that the routing device needs for production forwarding and control. That explains the specific symptom at the Elmfield engineering office. A direct corrective action is: Use targeted conditional debugging, capture only needed events and disable debug promptly.

Incorrect Answers

A:

The observation at the Elmfield engineering office does not point to syslog timestamp correlation; it points to a different condition. Unrestricted debug processing is consuming resources that the routing device needs for production forwarding and control.

C:

That diagnosis belongs to dhcp declined conflicts, while the observation at the Elmfield engineering office points to conditional debug and router load.

The observation at the Elmfield engineering office does not point to syslog severity threshold; it points to a different condition. Unrestricted debug processing is consuming resources that the routing device needs for production forwarding and control.

Question 374

At the Granite manufacturing plant, a technician enables unrestricted high-volume routing debug on R-GRA-PE1, sharply increasing CPU load during a customer incident. Which underlying technical condition best accounts for this evidence?

  1. The remote logging level filters less-severe events before they are forwarded.
  2. Hosts are not signaled to use DHCPv6 for auxiliary information despite having SLAAC addresses.
  3. Unrestricted debug processing is consuming resources that the routing device needs for production forwarding and control.
  4. The DHCP pool includes addresses reserved for devices that are configured manually.

D:

That diagnosis belongs to dhcp excluded-address pool, while the observation at the Granite manufacturing plant points to conditional debug and router load.

Question 375

At the Aspen agricultural office, R-ASP-WAN1 sends discrete syslog alarms, but operators need continuous interface queue and utilization time series to investigate intermittent congestion. Which underlying technical condition best accounts for this evidence?

  1. Required DHCP relay-agent location information is missing from forwarded requests.
  2. Event-only syslog messages do not provide the periodic operational counter series requested.
  3. The DHCP pool includes addresses reserved for devices that are configured manually.
  4. Duplicate-address conflicts are withholding otherwise available pool addresses from assignment.

Explanation

Correct Answer

B:

This diagnosis fits the symptoms at the Aspen agricultural office. Event-only syslog messages do not provide the periodic operational counter series requested. The remedial action is: Configure supported model-driven telemetry or scheduled counter collection for the required performance paths.

Incorrect Answers

A:

This diagnoses a different mechanism: Required DHCP relay-agent location information is missing from forwarded requests. The reported symptom at the Aspen agricultural office instead concerns telemetry visibility versus only log events.

C:

The observation at the Aspen agricultural office does not point to dhcp excluded-address pool; it points to a different condition. Event-only syslog messages do not provide the periodic operational counter series requested.

D:

This diagnoses a different mechanism: Duplicate-address conflicts are withholding otherwise available pool addresses from assignment. The reported symptom at the Aspen agricultural office instead concerns telemetry visibility versus only log events.

  1. Client DHCP broadcasts are not forwarded across the router to the remote DHCP service.
  2. The DHCP pool includes addresses reserved for devices that are configured manually.
  3. The remote logging level filters less-severe events before they are forwarded.
  4. Hosts are not signaled to use DHCPv6 for auxiliary information despite having SLAAC addresses.

Explanation
