質問 # 16
What do most Discovery properties start with?
- A. glide.discovery
- B. discovery.prop
- C. disco.release
- D. glide.itom
正解：A
解説：
In ServiceNow Discovery, most properties related to the Discovery module start with the prefix
'glide.discovery'. This naming convention is part of ServiceNow's system property design, where 'glide' typically indicates system properties and 'discovery' specifies that the property is related to the Discovery module. Properties are used to configure various aspects of the Discovery process, such as behavior, timeouts, and performance settings.
質問 # 17
What are the main KPIs for CMDB Health scorecard?
Choose 3 answers
- A. Duplicates
- B. Correctness
- C. Completeness
- D. Staleness
- E. Compliance
正解：B、C、D
解説：
The main Key Performance Indicators (KPIs) for the CMDB Health scorecard in ServiceNow include Correctness, Completeness, and Staleness. These KPIs are critical for assessing the overall health and quality of the CMDB. Correctness refers to the accuracy of the data in the CMDB, Completeness measures whether all required CI data is present, and Staleness indicates the freshness or timeliness of the CI data. Compliance and Duplicates, while important, are not considered main KPIs in the context of the CMDB Health scorecard.

質問 # 18
Which of the following are contained in an extension section of a discovery pattern?
- A. Connection sections
- B. Identification sections
- C. Network libraries
- D. Shared libraries
正解：D
解説：
An extension section of a discovery pattern is a section that allows you to modify or extend the functionality of an existing pattern without customizing it. An extension section can contain shared libraries, which are reusable code snippets that can be invoked from any pattern or extension section. Shared libraries can be used to define common functions, variables, or constants that are used across multiple patterns or extension sections. Shared libraries can also be used to override the default behavior of some built-in functions, such as identification or classification12.

質問 # 19
Which choice best describes the Reconciliation process?
- A. The process of normalizing applications, to allow the data to be used by Software Asset Management.
- B. The process of reconciling a deleted Cl, if it is identified as a duplicate. The result is stored in de-duplication tasks.
- C. The process of reconciling uniquely identifying Cis. to determine if the Cl already exists in the CMDB or if it is a newly discovered Cl.
- D. The process of reconciling Cis and Cl attributes by allowing only designated authoritative data sources to write to the CMDB at the Cl table and attribute level.
正解：D
解説：
The reconciliation process in ServiceNow refers to the method of ensuring data integrity and consistency in the Configuration Management Database (CMDB) by allowing only designated authoritative data sources to write or update information at the CI (Configuration Item) table and attribute level. This process helps maintain accurate and reliable data in the CMDB by controlling how and from where data is sourced and updated. The other options describe different processes or aspects of CMDB management and are not directly related to the reconciliation process. References = ServiceNow CMDB documentation, particularly the sections on CI data management and reconciliation processes.
質問 # 20
A discovery pattern of type application can be used by both Horizontal Discovery and Vertical Discovery.
Response:
- A. True.
- B. false.
正解：A
質問 # 21
Which of the following choices explain differences between Service Mapping and Discovery? (Choose two.)
- A. Discovery finds applications and devices on your network, Service Mapping monitors those devices.
- B. Discovery requires agent installation to find hardware devices, Service Mapping requires agents for software.
- C. Discovery addresses inventory-related use-cases, while Service Mapping allows for the creation of accurate maps of application service topologies.
- D. Discovery utilizes IP address ranges for initial discovery, Service Mapping uses entry points.
正解：C、D
解説：
Discovery and Service Mapping are both products that help to identify and map the IT infrastructure and services in an organization. However, they have different approaches and objectives. Discovery uses IP address ranges as the starting point for finding devices and applications on the network, and then runs probes and sensors to collect information and classify them. Discovery focuses on inventory-related use-cases, such as asset management, configuration management, and compliance. Service Mapping uses entry points, such as URLs or host names, as the starting point for mapping business services and their dependencies. Service Mapping runs patterns, which are sequences of operations that follow the traffic connections between devices and applications, and then creates a service map that shows the logical and semantic relationships. Service Mapping focuses on service-related use-cases, such as service availability, impact analysis, and root cause analysis12.

質問 # 22
How many CI Identifiers can be configured per CI Class?
Response:
- A. 0
- B. 1
- C. 2
- D. 3
正解：B
質問 # 23
Which of the choices have a higher chance of leading to lost data during CI reclassification? (Choose two.)
- A. Upgrading
- B. Downgrading
- C. Switching
- D. Identifying
正解：B、C
解説：
CI reclassification is the process of changing the class of a CI in the CMDB based on the discovery data. It can be done manually or automatically, depending on the configuration settings. CI reclassification can result in data loss if the new class has fewer or different attributes than the original class, and the existing attribute values are not preserved or mapped to the new class. This can happen when a CI is switched to a different class hierarchy, such as from a Linux Server to a Windows Server, or when a CI is downgraded to a less specific class, such as from a Database to a Software Instance. Therefore, switching and downgrading have a higher chance of leading to lost data during CI reclassification.

質問 # 24
In a pattern operation, which of the following correctly calls the value of the executableDir variable from the tabular process variable?
- A. $process.executableDir
- B. process(executableDir)
- C. "process_executableDir"
- D. $process_executableDir
正解：A
解説：
The $process.executableDir expression correctly calls the value of the executableDir variable from the tabular process variable. The process variable is a tabular variable that contains the output of the ps command, which lists the processes running on a CI. The executableDir variable is a column name that holds the directory path of the executable file for each process. To access the value of a column name from a tabular variable, you need to use the dot notation, such as $variable.columnName12.

質問 # 27
From the Discovery Status record, which of the following does a Device record contain?
- A. contains a link to the discovered Cl
- B. the CMDB Health Dashboard link
- C. contains a link to the discovered Asset
- D. the contents of the discovered Cl
正解：A
解説：
From the Discovery Status record, a Device record in ServiceNow Discovery contains a link to the discovered Configuration Item (CI). This link provides direct access to the CI record that was discovered and processed during the discovery cycle. The Device record does not contain the contents of the CI, a link to the discovered Asset, or a link to the CMDB Health Dashboard. References = ServiceNow Discovery documentation, focusing on the details of Discovery Status records and the information contained within Device records.
