Which of the following is a best practice for identifying the most effective services with which to start an iterative ITSI deployment?
- A. Define a large number of key services early.
- B. Focus on low-level services.
- C. Only include KPIs if they will be used in multiple services.
- D. Analyze the business to determine the most critical services.
正解：C
質問 # 28
Which of the following is a characteristic of base searches?
- A. Search expression, entity splitting rules, and thresholds are configured at the base search level.
- B. It is possible to filter to entities assigned to the service for calculating the metrics for the service's KPIs.
- C. The fewer KPIs that share a common base search, the more efficiency a base search provides, and anomaly detection is more efficient.
- D. The base search will execute whether or not a KPI needs it.
正解：B
解説：
Reference:
A base search is a search definition that can be shared across multiple KPIs that use the same data source. Base searches can improve search performance and reduce search load by consolidating multiple similar KPIs. One of the characteristics of base searches is that it is possible to filter to entities assigned to the service for calculating the metrics for the service's KPIs. This means that you can use entity filtering rules to specify which entities are relevant for each KPI based on the base search results. Reference: Create KPI base searches in ITSI, [Filter entities for KPIs based on base searches]
質問 # 29
When deploying ITSI on a distributed Splunk installation, which component must be installed on the search head(s)?
- A. All ITSI components
- B. SA-ITOA
- C. SA-ITSI-Licensechecker
- D. ITSI app
正解：D
解説：
Install SA-ITSI-Licensechecker and SA-UserAccess on any license master in a distributed or search head cluster environment. If a search head in your environment is also a license master, the license master components are installed when you install ITSI on the search heads.
Reference:
When deploying ITSI on a distributed Splunk installation, the component that must be installed on the search head(s) is the ITSI app. The ITSI app contains the main features and functionality of ITSI, such as service creation and management, KPI configuration, glass table creation and editing, episode review, deep dives, and so on. The ITSI app also contains some add-ons that provide additional functionality, such as SA-ITOA (IT Operations Analytics), SA-UserAccess (User Access Management), and SA-Utils (Utility Functions). The ITSI app must be installed on the search head(s) because it handles the search management and presentation functions for ITSI. Reference: Install IT Service Intelligence in a distributed environment
質問 # 30
In distributed search, which components need to be installed on instances other than the search head?
- A. SA-ITSI-Licensechecker on indexers.
- B. SA-IndexCreation and SA-ITOA on indexers; SA-ITSI-Licensechecker and SA-UserAccess on the license master.
- C. SA-IndexCreation and SA-ITSI-Licensechecker on indexers.
- D. SA-IndexCreation on idexers; SA-ITSI-Licensechecker and SA-UserAccess on the license master.
正解：C
解説：
SA-IndexCreation is required on all indexers. For non-clustered, distributed environments, copy SA-IndexCreation to $SPLUNK_HOME/etc/apps/ on individual indexers.
Reference:
In distributed search, the components that need to be installed on instances other than the search head are SA-IndexCreation and SA-ITSI-Licensechecker on indexers. SA-IndexCreation is an add-on that creates the indexes required by ITSI, such as itsi_summary and itsi_tracked_alerts. SA-ITSI-Licensechecker is an add-on that monitors the license usage of ITSI and generates alerts when the license limit is exceeded or about to expire. These components need to be installed on indexers because they handle the data ingestion and storage functions for ITSI. The other components, such as ITSI app and SA-ITOA, need to be installed on the search head(s) because they handle the search management and presentation functions for ITSI. Reference: Install IT Service Intelligence in a distributed environment
質問 # 31
Which of the following describes entities? (Choose all that apply.)
- A. To automatically restrict the KPI to only the entities in a particular service, select "Filter to Entities in Service".
- B. Multiple entities can share the same alias value, but must have different role values.
- C. An abstract (pseudo/logical) entity can be used to split by for a KPI, although no entity rules or filtering can be used to limit data to a specific service.
- D. Entities must be IT devices, such as routers and switches, and must be identified by either IP value, host name, or mac address.
正解：A、C
解説：
Reference:
Entities are IT components that require management to deliver an IT service. Each entity has specific attributes and relationships to other IT processes that uniquely identify it. Entities contain alias fields and informational fields that ITSI associates with indexed events. Some statements that describe entities are:
B) An abstract (pseudo/logical) entity can be used to split by for a KPI, although no entity rules or filtering can be used to limit data to a specific service. An abstract entity is an entity that does not represent a physical host or device, but rather a logical grouping of data sources. For example, you can create an abstract entity for each business unit in your organization and use it to split by for a KPI that measures revenue or customer satisfaction. However, you cannot use entity rules or filtering to limit data to a specific service based on abstract entities, because they do not have alias fields that match indexed events.
D). To automatically restrict the KPI to only the entities in a particular service, select "Filter to Entities in Service". This option allows you to filter the data sources for a KPI by the entities that are assigned to the service. For example, if you have a service for web servers and you want to monitor the CPU load percent for each web server entity, you can select this option to ensure that only the events from those entities are used for the KPI calculation.
質問 # 32
When changing a service template, which of the following will be added to linked services by default?
- A. Health score.
- B. Entity Rules.
- C. New KPIs.
- D. Thresholds.
正解：B
解説：
Explanation
Link multiple services to a service template to manage them collectively in IT Service Intelligence (ITSI). A service can only be linked to one service template at a time. When you link a service to a service template, any existing KPIs in the service are preserved and KPIs in the template are added to the service. You can choose to append, replace, or keep entity rules.
質問 # 33
In distributed search, which components need to be installed on instances other than the search head?
- A. SA-ITSI-Licensechecker on indexers.
- B. SA-IndexCreation and SA-ITOA on indexers; SA-ITSI-Licensechecker and SA-UserAccess on the license master.
- C. SA-IndexCreation and SA-ITSI-Licensechecker on indexers.
- D. SA-IndexCreation on idexers; SA-ITSI-Licensechecker and SA-UserAccess on the license master.
正解：C
質問 # 34
In maintenance mode, which features of KPIs still function?
- A. KPI calculations and threshold settings can be modified.
- B. KPI searches will execute but will be buffered until the maintenance window is over.
- C. New KPIs can be created, but existing KPIs are locked.
- D. KPI searches still run during maintenance mode, but results go to itsi_maintenance_summary index.
正解：B
解説：
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.
Reference:
A is the correct answer because KPI searches still run during maintenance mode, but the results are buffered until the maintenance window is over. This means that no alerts are triggered during maintenance mode, but once it ends, the buffered results are processed and alerts are generated if necessary. You cannot create new KPIs or modify existing KPIs during maintenance mode. Reference: [Overview of maintenance windows in ITSI]
質問 # 35
Which of the following items describe ITSI Backup and Restore functionality? (Choose all that apply.)
- A. ITSI backups are stored as a collection of JSON formatted files.
- B. kvstore_to_json.py can be used in scripts or command line to backup ITSI for full or partial backups.
- C. A pre-configured default ITSI backup job is provided that can be modified, but not deleted.
- D. ITSI backup is inclusive of KV Store, ITSI Configurations, and index dependencies.
正解：A、B
解説：
ITSI provides a kvstore_to_json.py script that lets you backup/restore ITSI configuration data, perform bulk service KPI operations, apply time zone offsets for ITSI objects, and regenerate KPI search schedules.
When you run a backup job, ITSI saves your data to a set of JSON files compressed into a single ZIP file.
Reference:
https://docs.splunk.com/Documentation/ITSI/4.10.2/Configure/kvstorejson
https://docs.splunk.com/Documentation/ITSI/4.10.2/Configure/BackupandRestoreITSIconfig C and D are correct answers because ITSI backup and restore functionality uses kvstore_to_json.py as a command line script or as part of custom scripts to backup ITSI data for full or partial backups. ITSI backups are also stored as a collection of JSON formatted files that contain KV store objects such as services, KPIs, glass tables, etc. A is not a correct answer because there is no pre-configured default ITSI backup job provided. You can create your own backup jobs or use the command line script or custom scripts to backup ITSI data. B is not a correct answer because ITSI backup is not inclusive of index dependencies. ITSI backup only includes KV store objects and optionally some .conf files. You need to use other methods to backup index data. Reference: [Overview of backing up and restoring ITSI KV store data], [Create a full backup of ITSI], [Create a partial backup of ITSI]
質問 # 36
What is the default importance value for dependent services' health scores?
- A. 0
- B. 1
- C. 2
- D. Unassigned
正解：C
解説：
Explanation
By default, impacting service health scores have an importance value of 11.
質問 # 37
When in maintenance mode, which of the following is accurate?
- A. Service health scores and KPI events are deleted until the window is over.
- B. Maintenance mode slots are scheduled on a per hour basis.
- C. KPIs are shown in blue while in maintenance mode.
- D. Once the window is over, KPIs and notable events will begin to be generated again.
正解：D
解説：
Reference:
A is the correct answer because when in maintenance mode, KPIs and notable events will begin to be generated again once the window is over. Maintenance mode is a feature of ITSI that allows you to temporarily suspend alerts and health score calculations for a service or an entity during planned maintenance or downtime. During maintenance mode, KPI searches still run, but the results are buffered until the window is over. Once the window is over, the buffered results are processed and alerts and health scores are generated if necessary. Reference: [Overview of maintenance windows in ITSI]
質問 # 38
Which index contains ITSI Episodes?
- A. itsi_notable_archive
- B. itsi_summary
- C. itsi_tracked_alerts
- D. itsi_grouped_alerts
正解：A
質問 # 39
Where are KPI search results stored?
- A. KV Store.
- B. The default index.
- C. Output to a CSV lookup.
- D. The itsi_summary index.
正解：D
解説：
Search results are processed, created, and written to the itsi_summary index via an alert action.
Reference:
D is the correct answer because KPI search results are stored in the itsi_summary index in ITSI. This index is an events index that stores the results of scheduled KPI searches. Summary indexing lets you run fast searches over large data sets by spreading out the cost of a computationally expensive report over time. Reference: Overview of ITSI indexes
質問 # 40
Which of the following is a best practice when configuring maintenance windows?
- A. Disable any glass tables that reference a KPI that is part of an open maintenance window.
- B. Give the maintenance window a buffer, for example, 15 minutes before and after actual maintenance work.
- C. Develop a strategy for configuring a service's notable event generation when the service's maintenance window is open.
- D. Change the color of services and entities that are part of an open maintenance window in the service analyzer.
正解：B
解説：
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.
Reference:
A maintenance window is a period of time when a service or entity is undergoing maintenance operations or does not require active monitoring. It is 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. For example, if a server will be shut down for maintenance at 1:00PM and restarted at 5:00PM, the ideal maintenance window is 12:30PM to 5:30PM. The 15- to 30-minute time buffer is a rough estimate based on 15 minutes being the time period over which most KPIs are configured to search data and identify alert triggers. Reference: Overview of maintenance windows in ITSI
質問 # 41
Which scenario would benefit most by implementing ITSI?
- A. Monitoring of business services functionality.
- B. Monitoring of system process statuses
- C. Monitoring of retail sales metrics.
- D. Monitoring of system hardware.
正解：A
解説：
Reference:
Splunk IT Service Intelligence (ITSI) is a monitoring and analytics solution that uses artificial intelligence and machine learning to provide insights into the health and performance of IT services. ITSI lets you create services that represent the critical components of your IT infrastructure, such as applications, databases, servers, networks, and so on. You can then monitor the status and performance of these services using key performance indicators (KPIs), which are metrics that measure aspects of service health, such as availability, latency, error rate, and so on. ITSI also provides tools for visualizing, investigating, and alerting on service issues, such as service analyzers, glass tables, deep dives, episode review, and so on. The scenario that would benefit most by implementing ITSI is monitoring of business service functionality, because ITSI enables you to measure and improve the quality and reliability of your IT services and align them with your business objectives. Reference: What is Splunk IT Service Intelligence?
質問 # 42
When must a service define entity rules?
- A. If the intention is for the KPIs in the service to have different aggregate vs. entity KPI values.
- B. If some or all of the KPIs in the service will be split by entity.
- C. To enable entity cohesion anomaly detection.
- D. If the intention is for the KPIs in the service to filter to only entities assigned to the service.
正解：D
解説：
Provide a value to filter the service to a specific set of entities. These entity rule values are meant to be custom for each service.
Reference:
A is the correct answer because a service must define entity rules if the intention is for the KPIs in the service to filter to only entities assigned to the service. Entity rules are filters that match entities to services based on entity aliases or entity metadata. If you enable the Filter to Entities in Service option for a KPI, you need to define entity rules for the service to ensure that the KPI search results only include the relevant entities for the service. Otherwise, the KPI search results might include entities that are not part of the service or exclude entities that are part of the service. Reference: [Define entities for a service in ITSI], [Configure KPI settings in ITSI]
質問 # 43
Which index will contain useful error messages when troubleshooting ITSI issues?
- A. itsi_notable_audit
- B. _internal
- C. itsi_summary
- D. _introspection
正解：B
解説：
Reference:
The index that will contain useful error messages when troubleshooting ITSI issues is:
B) _internal. This is true because the _internal index contains logs and metrics generated by Splunk processes, such as splunkd and metrics.log. These logs can help you diagnose problems with your Splunk environment, including ITSI components and features.
The other indexes will not contain useful error messages because:
A) _introspection. This is not true because the _introspection index contains data about Splunk resource usage, such as CPU, memory, disk space, and so on. These data can help you monitor the performance and health of your Splunk environment, but not the error messages.
C) itsi_summary. This is not true because the itsi_summary index contains summarized data for your KPIs and services, such as health scores, severity levels, threshold values, and so on. These data can help you analyze the trends and anomalies of your IT services, but not the error messages.
D) itsi_notable_audit. This is not true because the itsi_notable_audit index contains audit data for your notable events and episodes, such as creation time, owner
質問 # 44
There are two departments using ITSI. Finance and Sales. Analysts in each department should not be allowed to see each other's services. What are the role configuration steps required to accomplish this?
- A. itoa_finance_admin, inherited from itoa_team_admin; itoa_sales_admin, inherited from itoa_team_admin; itoa_finance_analyst, inherited from itoa_analyst; itoa_sales_analyst, inherited from itoa_analyst.
- B. itoa_finance_admin, inherited from itoa_admin; itoa_sales_admin, inherited from itoa_team_admin; itoa_finance_analyst, inherited from itoa_analyst; itoa_sales_analyst, inherited from itoa_team_analyst.
- C. itoa_finance_admin, inherited from itoa_admin; itoa_sales_admin, inherited from itoa_team_admin; itoa_finance_analyst, inherited from itoa_analyst; itoa_sales_analyst, inherited from itoa_analyst.
- D. itoa_finance_admin, inherited from itoa_admin; itoa_sales_admin, inherited from itoa_team_admin; itoa_finance_analyst, inherited from itoa_team_analyst; itoa_sales_analyst, inherited from itoa_team_analyst.
正解：B
解説：
C is the correct answer because teams are a feature of ITSI that allow you to restrict access to service content in UI views based on user roles. To create separate teams for finance and sales analysts, you need to create custom roles that inherit from the itoa_analyst role, which has read-only access to ITSI content. For example, you can create itoa_finance_analyst and itoa_sales_analyst roles that inherit from itoa_analyst. Then, you need to create custom teams that include these roles and assign them to the relevant services. For example, you can create a finance team that includes the itoa_finance_analyst role and assign it to the finance services. Similarly, you can create a sales team that includes the itoa_sales_analyst role and assign it to the sales services. This way, analysts in each department can only see their own services and not each other's. Reference: Create teams in ITSI, Assign teams to services in ITSI

Which ITSI functions generate notable events? (Choose all that apply.)
- A. KPI threshold breaches.
- B. Multi-KPI alert.
- C. Correlation search.
- D. KPI anomaly detection.
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.
