Which choice will populate the Location field for a discovered CI?
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.

What role is needed by the MID Server's user account to interact with a ServiceNow instance?
A
Explanation:
The MID Server’s user account must have the mid_server role to interact with a ServiceNow
instance. This role allows the MID Server to access protected tables and perform discovery and
orchestration tasks on behalf of the instance. The other roles are not related to the MID Server
functionality. The discovery_admin role is for configuring and managing discovery, the sm_mid role is
for using the Service Mapping MID Server, and the mid_discovery role is for running discovery probes
and sensors.

Which operation is used to change from the default credentials to any other appropriate credentials
in a horizontal pattern?
B
Explanation:
A horizontal pattern is a type of Discovery pattern that discovers configuration items (CIs) and their
relationships by moving across the network from one device to another. A horizontal pattern can use
the Change user operation to switch from the default credentials to any other appropriate
credentials for a specific device or application. This operation allows the pattern to access different
types of CIs with different authentication methods.

After navigating to an Automaton Error Messages list from Discovery > Home, how are the options
on the right navigation pane categorized? (Choose two.)
A C
Explanation:
The Automation Error Messages list displays the errors that occurred during the execution of
Discovery automation scripts. From this list, you can view the details of each error, such as the script
name, the error message, the device, and the time. You can also perform actions on the errors, such
as retrying the script, ignoring the error, or creating an incident.
To do so, you can use the options on
the right navigation pane, which are categorized as follows1
:
SELECT ALL: This option allows you to select all the errors in the list.
SELECT ONE: This option allows you to select one error in the list by clicking on the checkbox next to
it.
ACTION ON SELECTED: This option allows you to perform an action on the selected errors, such as
Retry, Ignore, or Create Incident. You can also choose to perform the action on all the errors in the
list by selecting the All option from the drop-down menu.
ACTION ON ALL: This option allows you to perform an action on all the errors in the list, regardless of
the selection. You can choose from the same actions as the ACTION ON SELECTED option.

Discovery, and how to access and manage them.
Which of the following can be used in the Debug Identification Section in Debug Mode for an
infrastructure pattern? (Choose two.)
AD
Explanation:
The Debug Identification Section in Debug Mode allows you to specify the identification attributes of
a CI that you want to debug. These attributes are used to find the CI in the CMDB and run the pattern
on it. The identification attributes vary depending on the CI class, but for infrastructure patterns, the
common ones are IP and Host Name. These attributes are also used by the horizontal discovery to
identify CIs. AWS Endpoint and PID are not valid identification attributes for infrastructure patterns.
Reference: The explanation is based on the following sources:

With multiple CI data sources, which choice is the best for determining which source can update a CI
attribute?
D
Explanation:
Reconciliation rules are used to determine which data sources can update CI attributes in
ServiceNow. Reconciliation rules can be static or dynamic, and they can be applied to specific CI
classes, attributes, or discovery sources.
Reconciliation rules can also specify the actions to take
when there are unmatched values, such as removing, ignoring, or updating them1
.

Which method for deleting specific CIs is not discovered in 30 days?
A
Explanation:
A scheduled job is a background process that runs at a specified time or interval to perform a specific
task1
. It is not a method for deleting specific CIs that are not discovered in 30 days. The other options
are methods for deleting or updating CIs based on discovery data.
A UI policy is a script that can
dynamically change the behavior of a form or list2
.
A service mapping is a process that creates a map
of the relationships between CIs that support a business service3
. A data policy is a rule that enforces
data consistency and accuracy by validating the data entered into a record.

Which of the following choices must be installed on a MID Server to run Credential-less Discovery?
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
.

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?
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.

The CMDB contains which of the following record types? (Choose two.)
BD
Explanation:
The CMDB contains records of configuration items (CIs) and their relationships. A CI is any
component that needs to be managed in order to deliver an IT service, such as a server, an
application, or a user. A relation type defines the nature of the connection between two CIs, such as
depends on, uses, or contains. A model is a template for a CI that defines its attributes and default
values. An asset is a tangible or intangible resource that is tracked and managed by the organization,
such as a laptop, a license, or a contract.
