- A. Send email.
- B. Run a script.
- C. Ping a host.
- D. Include in RSS feed.
正解: A,B,D
解説:
Explanation

質問 34
For which ITSI function is it a best practice to use a 15-30 minute time buffer?
- A. Anomaly detection.
- B. Adaptive thresholding.
- C. Correlation searches.
- D. Maintenance windows
正解: D
解説:
Explanation
It's a best practice to schedule maintenance windows with a 15- to 30-minute time buffer before and after you start and stop your maintenance work. This gives the system an opportunity to catch up with the maintenance state and reduces the chances of ITSI generating false positives during maintenance operations.
質問 35
Which of the following are deployment recommendations for ITSI? (Choose all that apply.)
- A. Deployments often require an increase of hardware resources above base Splunk requirements.
- B. Deployments should use fastest possible disk arrays for indexers.
- C. Deployments may increase the number of required indexers based on the number of KPI searches.
- D. Deployments require a dedicated ITSI search head.
正解: A,C,D
解説:
Explanation
You might need to increase the hardware specifications of your own Enterprise Security deployment above the minimum hardware requirements depending on your environment.
Install Splunk Enterprise Security on a dedicated search head or search head cluster.
The Splunk platform uses indexers to scale horizontally. The number of indexers required in an Enterprise Security deployment varies based on the data volume, data type, retention requirements, search type, and search concurrency.
質問 36
Which of the following is a valid type of Multi-KPI Alert?
- A. Rise over run.
- B. Score over composite.
- C. Status over time.
- D. Value over time.
正解: C
質問 37
Which ITSI functions generate notable events? (Choose all that apply.)
- A. Correlation search.
- B. Multi-KPI alert.
- C. KPI anomaly detection.
- D. KPI threshold breaches.
正解: A,C,D
解説:
Explanation
After you configure KPI thresholds, you can set up alerts to notify you when aggregate KPI severities change.
ITSI generates notable events in Episode Review based on the alerting rules you configure.
Anomaly detection generates notable events when a KPI IT Service Intelligence (ITSI) deviates from an expected pattern.
Notable events are typically generated by a correlation search.
質問 38
What is the default importance value for dependent services' health scores?
- A. 0
- B. 1
- C. Unassigned
- D. 2
正解: B
解説:
Explanation
By default, impacting service health scores have an importance value of 11.
質問 39
Which scenario would benefit most by implementing ITSI?
- A. Monitoring of system hardware.
- B. Monitoring of system process statuses
- C. Monitoring of retail sales metrics.
- D. Monitoring of business services functionality.
正解: D
質問 40
What effects does the KPI importance weight of 11 have on the overall health score of a service?
- A. At least 10% of the KPIs will go critical.
- B. The service will go critical.
- C. It is a minimum health indicator KPI.
- D. Importance weight is unused for health scoring.
正解: C
質問 41
Which of the following applies when configuring time policies for KPI thresholds?
- A. It is possible for multiple time policies to overlap.
- B. They are great if you expect normal behavior at 1:00 to be different than normal behavior at 5:00
- C. A person can only configure 24 policies, one for each hour of the day.
- D. If a person expects a KPI to change significantly through a cycle on a daily basis, don't use it.
正解: A
解説:
Explanation
If you're creating multiple time policies that require the same threshold values, you can save time by copying the threshold levels and their corresponding values from one policy to another.
質問 42
ITSI Saved Search Scheduling is configured to use realtime_schedule = 0. Which statement is accurate about this configuration?
- A. If this value is set to 0, the scheduler might skip some execution periods to make sure that the scheduler is executing the searches running over the most recent time range.
- B. If this value is set to 0, the scheduler bases its determination of the next scheduled search execution time on the current time.
- C. If this value is set to 0, the scheduler bases its determination of the next scheduled search on the last search execution time.
- D. If this value is set to 0, the scheduler may skip scheduled execution periods.
正解: C
解説:
Explanation
If set to 0, the scheduler determines the next scheduled search run time based on the last run time for the search. This is called continuous scheduling.
