Question 770

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 continuing operational control is most directly relevant to preventing this problem?

  1. Review syslog severity and collection capacity after troubleshooting requirements change.
  2. Use time-bounded, conditionally scoped debug procedures with active CPU monitoring.
  3. Reconcile DHCP exclusions with static inventories whenever subnet assignments change.
  4. Monitor clock synchronization and timestamp settings across infrastructure devices.

Explanation

Correct Answer

D:

This control monitors the relevant configuration or operational behavior at the Ironwood training campus. Monitor clock synchronization and timestamp settings across infrastructure devices. It targets the condition described in the stem.

Incorrect Answers

A:

This would manage a different failure pattern. The remote logging level filters less-severe events before they are forwarded. It is not the most direct recurring check for syslog timestamp correlation at the Ironwood training campus.

B:

That safeguard protects against conditional debug and router load, not the concrete risk described at the Ironwood training campus. Unsynchronized device time makes otherwise collected logs unreliable for cross-device event correlation.

C:

This is useful for another concern: Reconcile DHCP exclusions with static inventories whenever subnet assignments change. It does not continuously test syslog timestamp correlation at the Ironwood training campus.

Question 771

At the Hillcrest research lab, a remote syslog collector receives critical events but not informational interface-change records from R-HCR-RT1. Which continuing operational control is most directly relevant to preventing this problem?

  1. Use time-bounded, conditionally scoped debug procedures with active CPU monitoring.
  2. Review syslog severity and collection capacity after troubleshooting requirements change.
  3. Monitor clock synchronization and timestamp settings across infrastructure devices.
  4. Define metric sampling and retention separately from event logging policies.

Explanation

Correct Answer

B:

This control monitors the relevant configuration or operational behavior at the Hillcrest research lab. Review syslog severity and collection capacity after troubleshooting requirements change. It targets the condition described in the stem.

Incorrect Answers

Question 775

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 continuing operational control is most directly relevant to preventing this problem?

  1. Define metric sampling and retention separately from event logging policies.
  2. Use time-bounded, conditionally scoped debug procedures with active CPU monitoring.
  3. Monitor DHCP conflicts and investigate their source instead of routinely clearing them blind.
  4. Audit helper-address settings and relay reachability on every client VLAN.

Explanation

Correct Answer

A:

The safeguard follows the failure mechanism at the Aspen agricultural office. Define metric sampling and retention separately from event logging policies.

Incorrect Answers

B:

This is useful for another concern: Use time-bounded, conditionally scoped debug procedures with active CPU monitoring. It does not continuously test telemetry visibility versus only log events at the Aspen agricultural office.

C:

This would manage a different failure pattern. Duplicate-address conflicts are withholding otherwise available pool addresses from assignment. It is not the most direct recurring check for telemetry visibility versus only log events at the Aspen agricultural office.

D:

That safeguard protects against ipv4 dhcp relay for remote server, not the concrete risk described at the Aspen agricultural office. Event-only syslog messages do not provide the periodic operational counter series requested.

Question 776
