CIS-DF Ingest Practice Test 3 — 15 Questions

Question 1

An administrator is configuring a Service Graph Connector to ingest client workstations. During test runs, they notice that workstations with identical hostnames but different serial numbers are being incorrectly merged into a single CI. Where should the administrator check and modify the matching criteria to ensure serial number is prioritized over hostname?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

CI Class Manager -> Select cmdb_ci_computer -> Identification Rule -> Adjust criteria precedence and attribute selection. Identification rule priority and criteria order in CI Class Manager govern which attributes are evaluated first and how matching takes place.

Answer

Data Source Precedence rules for workstations

Answer

Robust Transform Map Coalesce order

Answer

Discovery Schedule IP range filters

Question 2

An architect is troubleshooting an integration payload processed by the Identification and Reconciliation Engine (IRE) that resulted in an error. Which THREE of the following scenarios commonly trigger IRE processing errors? (Choose three.)

Accepted Answer

The incoming payload is missing attributes required by the class's identification rule criteria.. Common IRE errors involve missing mandatory identification attributes, invalid reference payloads, or unresolvable dependent relationships.

Answer

The target table does not have any UI Policies defined on its form view.

Answer

The import set table row count exceeds 1,000 records per batch.

Question 3

An administrator is designing identification rules for a custom CI class in the CMDB. Which THREE ofg the following best practices should be followed when configuring identification rules? (Choose three.)

Accepted Answer

Use attributes that are guaranteed to be unique and immutable, such as serial numbers or hardware asset tags.. Good identification rule design ensures uniqueness, avoids overly broad criteria, and uses reliable hardware attributes like serial numbers or MAC addresses.

Answer

Ensure that identification rules are created on custom tables without inheriting from cmdb_ci.

Answer

Configure every single attribute of the CI class into a single compound identification rule entry to ensure maximum security.

Question 4

When reviewing data ingestion methods for the ServiceNow CMDB, which TWO methods natively invoke the Identification and Reconciliation Engine (IRE) out of the box? (Choose two.)

Accepted Answer

Service Graph Connectors. ServiceNow Discovery and Service Graph Connectors use the IRE natively, whereas legacy import sets require configuration to use RTE/IRE.

Answer

Direct manual table inserts via background scripts using GlideRecord

Answer

Standard Email Inbound Actions creating incident records

Answer

Legacy Transform Maps with standard Coalesce settings

Question 5

An organization wants to ingest data into the CMDB using the Robust Transform Engine (RTE). Which TWO of the following capabilities are provided by RTE? (Choose two.)

Accepted Answer

Transforming complex hierarchical JSON or XML payloads into structured tabular data for IRE processing.. RTE supports complex data ingestion, hierarchical data mapping, and direct integration with the IRE.

Answer

Managing user authentication sessions for inbound REST API calls.

Answer

Replacing the underlying relational database management system with an in-memory graph store.

Answer

Automatically generating ITSM Change Requests for every ingested CI.

Question 6

An administrator is troubleshooting missing relationship data after running a custom data integration. Which THREE of the following factors should be investigated? (Choose three.)

Accepted Answer

Whether the payload structure correctly formats the related items or relationship blocks required by the IRE.. Missing relationships can result from unresolvable parent/child references, incorrect relationship type definitions, or improper payload syntax.

Answer

Whether the target CI table has active client scripts blocking the relationship field.

Answer

Whether the Discovery status schedule is set to 'Quick Discovery'.

Question 7

An enterprise is planning a data ingestion strategy for their CSDM implementation. Which TWO principles should guide their approach to data ingestion and the CMDB? (Choose two.)

Accepted Answer

Always route automated integrations through the Identification and Reconciliation Engine (IRE) to maintain data hygiene.. CSDM and CMDB best practices dictate avoiding legacy custom transforms that bypass IRE and leveraging authoritative automated sources.

Answer

Disable identification rules on all base classes to allow any data source to create records freely.

Answer

Rely exclusively on manual spreadsheet imports performed weekly for all infrastructure CIs.

Answer

Use legacy transform maps with direct GlideRecord insertions for all server ingestion to maximize performance.

Question 8

An administrator is configuring Data Source Precedence rules and notices unexpected attribute overwrites. Which THREE of the following conditions or settings can influence how Data Source Precedence behaves? (Choose three.)

Accepted Answer

The exact case-sensitive string value used for the discovery source in the payload.. Precedence behavior is influenced by discovery source string matching, class inheritance hierarchies, and attribute-level configurations.

Answer

The number of active user sessions currently logged into the ServiceNow instance.

Answer

Whether the attribute being updated is included in the class's identification rule criteria.

Question 9

When designing an integration using Robust Transform Engine (RTE), which TWO components must be configured to successfully ingest data into the CMDB? (Choose two.)

Accepted Answer

Robust Transform Engine Data Stream Definition and field maps. RTE requires data stream definitions and mapping configurations to transform and route payloads to the IRE.

Answer

Discovery schedule IP address ranges

Answer

Service Mapping application pattern criteria

Answer

Legacy Transform Map Coalesce scripts

Question 10

An administrator is reviewing the CMDB IRE execution logs and notices numerous warnings regarding payloads that skipped attribute updates. Which THREE of the following reasons would cause the IRE to skip updating an attribute on an existing CI? (Choose three.)

Accepted Answer

The attribute is configured to be ignored when incoming values are empty, and the incoming payload provided a blank value.. Attributes are skipped by the IRE when Data Source Precedence dictates a lower priority, when incoming values are identical, or when ignore-empty rules apply.

Answer

The target CI table has an active Business Rule that aborts all updates.

Answer

The user executing the integration does not have read access to the sys_user table.

Question 11

An administrator is troubleshooting an integration that uses Robust Transform Engine (RTE) to ingest software licenses. During testing, records are inserted into staging tables, but the RTE fails to push them into the CMDB via the IRE. Which THREE areas should the administrator inspect to diagnose the failure? (Choose three.)

Accepted Answer

CMDB Integration Results / IRE Execution Logs to identify specific payload rejection reasons.. Troubleshooting RTE-to-IRE integrations requires checking RTE data stream mappings, IRE identification rules, and integration error logs.

Answer

The Service Level Agreement (SLA) definition table for expired response times.

Answer

The UI Macro table for broken form decorators.

Question 12

An enterprise is setting up automated server discovery across multiple VLANs. Which TWO configuration steps are essential for ensuring Discovery successfully ingests this infrastructure? (Choose two.)

Accepted Answer

Configure Discovery Schedules with target IP ranges and associate appropriate credentials.. Successful discovery ingestion requires active MID Servers with network reachability and correct IP ranges associated with credentials.

Answer

Set all transform maps to coalesce on the sys_id field.

Answer

Create custom Business Rules on cmdb_ci to simulate Service Mapping.

Answer

Disable the Identification and Reconciliation Engine globally to speed up server creation.

Question 13

An organization is preparing to ingest data from an external asset tracking system into the ServiceNow CMDB using a custom REST API integration. Which THREE architectural components must be considered to ensure data integrity and prevent duplication? (Choose three.)

Accepted Answer

Establishing and verifying CI identification rules in CI Class Manager for all target classes.. Custom integrations require proper IRE invocation, unique identification rules, and standardized discovery source naming.

Answer

Writing custom Client Scripts to validate JSON payloads on form load.

Answer

Enabling 'Cascade Delete' on all reference fields in the target CMDB tables.

Question 14

When configuring Identification Rules in CI Class Manager, administrators can specify multiple criteria entries. Which TWO behaviors apply when multiple identification rule entries are defined for a single class? (Choose two.)

Accepted Answer

The IRE evaluates the identification rule entries in sequential order based on their priority ranking.. Multiple identification rule entries act as an OR condition where the IRE evaluates them in priority order.

Answer

Defining multiple entries automatically merges all matching records into a single record.

Answer

Identification rule entries only apply when ingestion is performed via legacy Import Sets.

Answer

All identification rule entries must match simultaneously for a CI to be identified.

Question 15

An administrator is reviewing Discovery results and notices that network switches are successfully discovered, but their associated switch ports are missing. Which TWO factors are most likely responsible for this ingestion gap? (Choose two.)

Accepted Answer

The dependent relationship payload structure for switch ports failed IRE validation or was omitted.. Missing switch ports during discovery can result from pattern configurations, SNMP walk limits, or dependent relationship payloads.

Answer

The cmdb_ci_ip_address table has read-only access enabled for all users.

Answer

Data Source Precedence rules marked switch ports as deprecated.

Answer

Discovery schedules were run outside of business hours.
