Question #1
Refer to the exhibit.
Based on this image, which of the following statements are true? (Choose three.)
- A . Attributes from two tables populate a table with the same name as a ServiceNow CMDB table.
- B . This operation is more than likely a part of a step on a pattern set to Application Pattern Type.
- C . If a value is unmatched, it is still merged into the Target Table.
- D . For this operation to run, there must be some data in the process.executablePath variable.
- E . This is a horizontal pattern of type "infrastructure."
Correct Answer: A, B, D
A, B, D
Explanation:
A is true because the target table $cmdb_ci_web_server is a ServiceNow CMDB table that stores information about web servers1.
B is true because the merge table operation is typically used for application patterns, which are horizontal patterns that discover applications and their dependencies. The condition on the process.executablePath variable suggests that the operation is looking for a specific application (mongoose) running on the web servers.
D is true because the merge table operation requires at least one matching field value between the two source tables1. In this case, the process.executablePath variable is the matching field, and it must contain “mongoose” for the operation to run.

Question #2
Refer to the exhibit.
Based on the following images, which choice best describes what occurs if Discovery sets the name attribute of a discovered Windows Server CI to ‘Windows1’ and then Altiris discovery runs detecting ‘Windows2’ for the name attribute on the same CI?
- A . The name of the CI stays ‘Windows1’.
- B . The name of the CI changes to ‘Windows2’.
- C . The name of the CI does not populate with either discovery.
- D . The CI is not discovered because Discovery is not listed in either image.
Correct Answer: B
B
Explanation:
In ServiceNow Discovery, the reconciliation process is governed by precedence rules. These rules determine which data source’s information will be retained if there are conflicts when multiple sources discover the same CI. In this case, Altiris has a higher order of precedence (300) compared to ServiceNow (100), as seen in the “Data Source Precedents” section of the image. Therefore, if Altiris discovers ‘Windows2’ for the name attribute on the same CI after ServiceNow sets it to ‘Windows1’, the name will change to ‘Windows2’ due to Altiris’s higher precedence.
Reference: The explanation is inferred from understanding how reconciliation and data source precedents work in ServiceNow Discovery, though not directly quoted from specific documents. You can find more information on these topics in the following links: Reconciliation

Question #3
For the Parse Variable pattern operation, what is required to have two different parsing methods to populate variables?
- A . Two different Debug Mode sessions.
- B . A tabular and a scalar variable.
- C . Two different steps.
- D . Two different Define Parsing selections on the same step.
Correct Answer: C
C
Explanation:
The Parse Variable pattern operation allows you to extract information from the output of a previous operation and save it in a variable. You can choose from different parsing methods, such as JSON File, XML File, Regular Expression, or Custom Script. To have two different parsing methods to populate variables, you need to use two different steps, each with a different Define Parsing selection.
For example, you can use one step to parse a JSON file and another step to parse an XML file. You cannot use two different parsing methods on the same step, as the Define Parsing selection is unique for each step.

- B . Creates only a list of discovered IPs in both IPv4 and IPv6 formats.
- C . Collects complete information from the scanned IP ranges and sends it to the CMDB.
- D . Directly populates records in the assets table.
Correct Answer: C
C
Explanation:
A Discovery schedule of type Configuration Item collects complete information from the scanned IP ranges and sends it to the CMDB. This type of schedule runs a series of probes and sensors to identify and classify the devices and applications on the network, and to create or update the corresponding configuration items in the CMDB. A Discovery schedule of type Configuration Item can also run patterns to discover more details and relationships about the configuration items.

Question #5
When installing a MID Server on a Windows platform, which right must be associated when creating a Service Account?
- A . Local Admin
- B . Domain Admin
- C . MID Server User Role
- D . Log on as service
Correct Answer: D
D
Explanation:
The Service Account for the MID Server must have the Log on as service right on the Windows platform. This right allows the MID Server to run as a Windows service and communicate with the ServiceNow instance. The Service Account does not need to have local or domain admin rights, as these are not required for the MID Server functionality. The MID Server User Role is a role on the ServiceNow instance, not on the Windows platform, and it is used to control the access and permissions of the MID Server on the instance.

Question #8
A discovery runs against a Windows Server returning the following attribute values for the first time:
name = WindowsSN1 serial_number = 12321
A subsequent discovery is ran against a different Windows Server returning the following attribute values: name = WindowsSN2
serial_number = 12321
With only base system CI Identifiers configured, which of the following is true?
- A . A Windows Server CI is created, then updated with WindowsSN2 as the name.
- B . Two Windows Sewer CIs are created, with WindowsSN1 AND WindowsSN2 for names.
- C . Two Windows Server CIs are created, without serial_number values.
- D . A Windows Server CI is created, then updated with WindowsSN1 as the name.
Correct Answer: B
B
Explanation:
According to the ServiceNow Discovery documentation, the base system CI Identifiers for Windows Server class are name and serial_number. These are the attributes that Discovery uses to uniquely identify a Windows Server CI. If both attributes match an existing CI, Discovery updates that CI. If only one attribute matches, Discovery creates a new CI. If neither attribute matches, Discovery also creates a new CI. In this scenario, the serial_number is the same for both Windows Servers, but the name is different. Therefore, Discovery will create two separate CIs, one with WindowsSN1 as the name and one with WindowsSN2 as the name.

Question #9
Which choice represents the three best ways of extending Discovery?
- A . Orchestration, Classifiers, Discovery Patterns
- B . Fingerprinting, Classifiers, Discovery Patterns
- C . Orchestration, Classifiers, Probes & Sensors
- D . Classifiers, Probes & Sensors, Discovery Patterns
- E . Classifiers, Fingerprinting, Probes & Sensors
Correct Answer: D
D
Explanation:
ServiceNow Discovery can be extended in three main ways: Classifiers, Probes & Sensors, and Discovery Patterns. Classifiers are used to identify the type of device or application that is being discovered, based on the information returned by a probe. Probes are commands or scripts that are executed on the target device or application to collect data. Sensors are scripts that process the data collected by probes and create or update configuration items (CIs) in the CMDB. Discovery Patterns are graphical representations of the discovery process that can be customized or created to discover specific types of devices or applications, using classifiers, probes, and sensors as building blocks.

SNMP Credentials require which of the following?
- A . write community strings
- B . usernames
- C . read community strings
- D . port 135 access
Correct Answer: C
C
Explanation:
SNMP credentials are used by Discovery to communicate with devices that support the Simple Network Management Protocol (SNMP). SNMP credentials do not include a user name, just a password, called the community string. The default read-only community string for many SNMP devices is public, and Discovery will try that automatically. Enter the appropriate SNMP credentials if they differ from the public community string1.

Which choice will populate the Location field for a discovered CI?
- A . Location field for a Discovery Schedule
- B . Location field for a parent CI Type
- C . Location field for a Port Probe
- D . Location report from the Discovery Dashboard
Correct Answer: A
A
Explanation:
The Location field for a discovered CI is populated by the Location field of the Discovery Schedule that triggered the discovery of that CI. This is done by the DiscoverySensor script, which gets the location ID from the Discovery Schedule and passes it to the Shazzam probe, which then updates the cidata with the location information. The Location field for a parent CI Type, a Port Probe, or a Discovery Dashboard report does not affect the Location field for a discovered CI.

Which of the following choices must be installed on a MID Server to run Credential-less Discovery?
- A . Credential-less Extension
- B . Nmap
- C . Advanced IP Scanner
- D . Defender
Correct Answer: B
B
Explanation:
Credential-less Discovery is a feature of ServiceNow Discovery that allows the instance to identify configuration items (CIs) without using credentials. Credential-less Discovery uses Network Mapper (Nmap), a free and open-source network scanner, to collect information about the CIs by sending packets and analyzing the responses. Nmap must be installed on the MID Server that runs Credential-less Discovery. Credential-less Discovery can be used as a fallback option when credential-based probes fail, or as a primary option for scanning certain types of devices, such as network devices, printers, or IoT devices12.

Question #19
A network device has both an SSH port and an SNMP port open. Discovery tries the SSH probe first and it fails. This triggers the SNMP probe, which succeeds. Discovery uses SNMP first for subsequent discoveries on that device.
What discovery functionality allows the above to happen?
- A . Classification
- B . Credential affinity
- C . MID Server affinity
- D . IP service affinity
Correct Answer: B
B
Explanation:
Credential affinity is an association between a set of credentials and a device on your network. When Discovery or Orchestration first attempts to access a device, they try all available credentials until a valid one is found. Once a valid credential is found, it is recorded in the dscy_credentials_affinity table, and further discovery processes rely on this information. If the credentials are modified or changed, the process will be repeated until a valid credential is found and updated in the same table. Credential affinity allows Discovery to use the most efficient and successful credential for each device, and avoid unnecessary credential failures.

Question #22
For CMDB Health, relationships can be which of the following choices? (Choose three.)
- A . Duplicate
- B . Stale
- C . Orphan
- D . Required
- E . Recommended
Correct Answer: ABC
ABC
Explanation:
CMDB Health measures the quality of the data in the CMDB by testing it against predefined rules and metrics. One of the categories of these rules is Correctness, which tests the data against data integrity rules such as identification rules, orphan CI rules, and stale CI rules1. These rules help identify and flag the existing CMDB relationships that are not compliant with the suggested relationships2.
Duplicate relationships are those that have more than one relationship of the same type between the same two CIs3. For example, if a server CI has two relationships of type “Depends on” with the same network CI, it is a duplicate relationship.
Stale relationships are those that have not been updated for a specified period of time3. For example, if a server CI has a relationship of type “Runs on” with a virtual machine CI that has not been discovered for more than 60 days, it is a stale relationship.
Orphan relationships are those that are missing a defined relationship within the CMDB3. For example, if a server CI has no relationship of type “Depends on” with any network CI, it is an orphan relationship.

- A . infrastructure_system
- B . The CI Type on the Discovery Pattern form
- C . windows_cmdb_ci
- D . computer_system
Correct Answer: AD
AD
Explanation:
Horizontal discovery patterns are a series of operations that tell Discovery which CIs to find on your network, what credentials to use, and what tables to populate in the CMDB. Horizontal discovery patterns use variables to store and pass information between the operations. By default, there are two variables that are automatically available for horizontal discovery patterns:
infrastructure_system and computer_system. These variables store the information about the infrastructure and the computer system of the target CI, respectively. They are populated by the Horizontal Pattern probe and sensor, which enable Discovery to use patterns for horizontal discovery123.

Question #28
Which choices are necessary to launch any pattern? (Choose two.)
- A . CI Classification
- B . CI Serial Number Attribute
- C . Data Certification
- D . CI Type
Correct Answer: AD
AD
Explanation:
To launch any pattern, you need to specify the CI classification and the CI type. The CI classification determines the table where the discovered CI is stored in the CMDB, and the CI type defines the specific attributes and relationships of the CI. For example, if you want to discover a Windows server, you need to select the CI classification as cmdb_ci_win_server and the CI type as Windows Server. These choices are mandatory for any pattern, as they enable Discovery to identify and classify the CIs correctly.

Question #31
A Discovery Schedule contains a /24 subnet IP Range and a Shazzam batch size of 5000.
How many times will a Shazzam probe be launched during discovery?
- A . 1
- B . 2
- C . 5000
- D . 254
Correct Answer: C
C
Explanation:
A /24 subnet IP Range means that there are 256 possible IP addresses in the range, from 0 to 255. A Shazzam batch size of 5000 means that Discovery will send 5000 ICMP packets at a time to scan the IP addresses. Therefore, Discovery will launch the Shazzam probe once for every 5000 IP addresses in the range, or 256 / 5000 = 0.0512 times. Since the number of times must be an integer, Discovery will round up to 1 and launch the Shazzam probe once. However, since the Shazzam probe is launched for each MID Server that is assigned to the Discovery Schedule, the actual number of times will depend on how many MID Servers are available. If there are N MID Servers, then the Shazzam probe will be launched N times, each sending 5000 ICMP packets to the same IP range. Therefore, the total number of times that the Shazzam probe will be launched during discovery is N * 1 = N.

- A . Classify Phase
- B . Scan Phase
- C . Exploration Phase
- D . Pattern Phase
- E . Identification Phase
Correct Answer: C
C
Explanation:
File-based Discovery is a process that helps identify what software is running on your Windows and UNIX servers and devices, even if there is no registration information available. File-based Discovery is triggered in the exploration phase of normal Discovery, after the target device has been classified and identified. File-based Discovery probes execute a scan searching for specific file extensions or file names in paths that you configure. The resulting file information is returned in the probe payload.
The sensor attempts to match the discovered files with installed software, using the file name, size, and version returned by the probe.
