CIS-DF Practice Test 4 — 25 Questions

Question 1

An enterprise is audited for CSDM compliance. The CSDM Data Foundations Dashboard indicates that application services are not properly connected to technical services. What is the governance impact of this structural gap?

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

Accepted Answer

Inability to accurately perform impact analysis during outages and incorrect service portfolio visibility. Unlinked application services prevent proper impact analysis, incident management escalation, and business service portfolio tracking.

Answer

Hardware assets will automatically be marked as deprecated

Answer

Database replication lag will increase across MID servers

Answer

Discovery will fail to run network scans on IP subnets

Question 2

An organization is ingesting printer CIs from a legacy asset system via Import Sets. Some incoming records contain a serial number with leading/trailing whitespace, causing the IRE to treat them as distinct CIs rather than matching existing ones. Where can data normalization be applied to clean this data before it reaches the IRE?

Accepted Answer

Use Robust Transform Engine (RTE) field transformations (such as Trim or Regex) during the data ingestion mapping phase.. Data normalization rules (Data Normalization plugin / Robust Transform Engine field transformations) can clean and standardize incoming data before IRE processing.

Answer

Modify the IRE Identification Rule to automatically ignore whitespace.

Answer

Write a Client Script on the target cmdb_ci table to strip whitespace upon insert.

Answer

Configure a Data Policy to reject records containing whitespace.

Question 3

An administrator is configuring a new Import Set to ingest third-party server data into the cmdb_ci_server table. During testing, they notice that records are being inserted as duplicates rather than updating existing CIs because the incoming payload lacks a unique identifier match. Which component should be configured to ensure the Identification and Reconciliation Engine (IRE) correctly identifies the existing CI?

Accepted Answer

Configure an Identification Rule in CI Class Manager for cmdb_ci_server.. Identification Rules are used by the IRE to determine if an incoming payload matches an existing CI in the CMDB, preventing duplicates.

Answer

Modify the coalesce setting on the Transform Map to use serial number.

Answer

Enable 'Robust Transform Engine' on the data source properties.

Answer

Create a Data Source Precedence rule for the import set.

Question 4

Which TWO of the following capabilities are provided out-of-the-box by the CMDB Health Dashboard? (Choose two.)

Accepted Answer

Answer

CMDB Health > Escalation Properties

Question 6

An administrator wants to view the hierarchical relationship and physical connections between a Business Application and its underlying database infrastructure in the CMDB. Which feature should they open from the Configuration Item form?

Accepted Answer

Dependency Views. The Dependency Views map provides a graphical representation of configuration items and their relationships, allowing administrators to visualize upstream and downstream dependencies.

Answer

Service Portfolio Management

Answer

Map Builder

Answer

CMDB Query Builder

Question 7

An organization uses Service Mapping to visualize an e-commerce application. A user notices that a specific entry point shows a 'Partial' map status. What does this Insight indicator specifically communicate?

Accepted Answer

Service Mapping encountered errors, missing credentials, or unmapped traffic during discovery of the service topology.. A partial status in Service Mapping indicates that the mapping engine encountered an error or missing credentials while traversing a specific CI or connection, resulting in an incomplete map.

Answer

The Discovery schedule is currently paused by an administrator.

Answer

The underlying infrastructure has not been updated within the last 90 days.

Answer

The business service record lacks mandatory CSDM technical service offerings.

Question 8

An enterprise configuration manager needs to audit all manual relationship modifications made to production servers over the last 30 days to ensure compliance with automated discovery policies. Which native audit mechanism tracks this?

Accepted Answer

Audit history on the Configuration Item Relationship [cmdb_rel_ci] table. Enhanced CMDB auditing and History sets / Audit logs on the cmdb_rel_ci table track relationship creations, modifications, and deletions.

Answer

Question 10

During a Dependency Views troubleshooting session, an engineer notices that a specific application server is missing its connected database nodes. What is the most likely cause when relationships are missing despite successful Discovery runs?

Accepted Answer

The relationship type filter in the Dependency Views UI is hiding specific relationship types.. Discovery identification and reconciliation engine (IRE) rules or payload payload processors might be dropping relationship payloads if parent/child identifiers don't match or if payload rules filter them out.

Answer

Data archiving automatically deletes relationship records older than 30 days.

Answer

The CMDB Query Builder cache needs to be manually cleared.

Answer

The cmdb_ci table has reached its maximum row count limit for relationships.

Question 11

An organization is troubleshooting a Service Mapping map where a discovery pattern fails to populate attributes for a custom application server. Which diagnostic tool helps inspect the raw payload and intermediate variables during pattern execution?

Question 14

A healthcare enterprise uses both ServiceNow Discovery and a third-party asset management tool to update server records in the CMDB. The third-party tool frequently populates stale operational status data. Using Data Source Precedence rules, how can the administrator ensure that ServiceNow Discovery always overrides the third-party tool for the 'Operational status' attribute on Linux servers?

Accepted Answer

Navigate to CI Class Manager, select cmdb_ci_linux_server, and configure Data Source Precedence to assign a higher priority to 'ServiceNow' than the third-party source for 'Operational status'.. Data Source Precedence rules allow administrators to define which data sources take precedence for specific attributes on specific classes.

Answer

Add a Business Rule on cmdb_ci that checks the sys_updated_by field and aborts updates from the third-party source.

Answer

Modify the Discovery schedule to run after the third-party integration job completes.

Answer

Create an Access Control List (ACL) that restricts write access on the cmdb_ci_linux_server table for the third-party integration user.

Question 15

A team needs to evaluate the overall health of their CSDM implementation by verifying if technical services are correctly linked to applications and infrastructure. Which built-in assessment tool provides this specific visibility?

Answer

Dependency Views baseline diff

Answer

CMDB Query Builder topology export

Answer

Discovery Schedule Log

Question 17

An organization discovers network gear using both SNMP Discovery and an external cloud management platform API. Both integrations populate the same physical switch CIs. The cloud platform sometimes sends an empty string for the serial number, which accidentally clears out valid serial numbers previously populated by SNMP Discovery. How can this be prevented using CMDB ingestion controls?

Accepted Answer

Configure IRE payload settings or Data Source Precedence rules to ignore empty or null attribute updates from specific data sources.. The IRE supports ignore empty attributes or data source precedence settings that prevent empty or null values from overwriting existing non-empty data.

Answer

Delete the identification rule for serial number.

Answer

Write an Inbound Email Action to reject empty payloads.

Answer

Set the serial number field dictionary attribute to 'read-only'.

Question 18

An administrator notices that when Discovery updates a virtual machine, the 'Environment' attribute populated by a manual spreadsheet import is overwritten, despite Data Source Precedence rules being configured. Upon investigation, they find that both sources are writing with the exact same discovery source string value. What is the correct way to resolve this conflict?

Accepted Answer

Configure the manual import to use a distinct discovery source string (e.g., 'Manual Import' or 'Spreadsheet') rather than sharing the default discovery source string.. If two different workflows or integrations use the exact same discovery source string, the IRE treats them as the same entity and precedence rules cannot distinguish between them.

Answer

Enable 'Coalesce' on the spreadsheet import transform map.

Answer

Modify the CI Class Manager identification rule to exclude the Environment attribute.

Answer

Set the table to read-only for the discovery integration user.

Question 19

An administrator is troubleshooting a custom integration where incoming JSON payloads for routers contain an array of interfaces. When the payload is processed, the parent router updates successfully, but none of the interface CIs are created. Reviewing the IRE payload structure shows that the interface objects are nested inside a property named `network_interfaces`. What must be configured in the IRE payload mapping to successfully process these child items?

Accepted Answer

Define a related items block in the payload structure mapping `network_interfaces` to the corresponding child class and relationship type.. When child items are nested in arrays within an IRE payload, related items / dependent relationships must be explicitly defined in the payload structure so the IRE iterates through the array.

Answer

Modify the Transform Map coalesce script to loop through the array.

Answer

Create a Business Rule to split the JSON array into individual rows on the import staging table.

Answer

Add 'network_interfaces' as a comma-separated string column in the base cmdb_ci table dictionary.

Question 20

An administrator is configuring a Robust Transform Engine (RTE) definition for a complex CMDB data import. They need to ensure that if an incoming record fails identification or has missing mandatory attributes, the entire batch does not fail, but instead logs an error for that specific row. Where is this error handling behavior managed in RTE?

Accepted Answer

Configure error handling options within the Robust Transform Engine Data Stream Definition and field processors to capture row-level exceptions.. RTE error handling and row-level logging are configured within the Robust Transform Engine definitions and associated data stream transformers.

Answer

Set the Import Set transform map property to 'Ignore Errors' globally.

Answer

Modify the IRE engine configuration property 'glide.cmdb.ire.abort_on_error' to false.

Answer

Write a global Business Rule on sys_import_set_row to catch exceptions.
