SERVICENOW-CIS-DISCOVERY CMDB Integration And Maintenance Practice Test 2 — 15 Questions

Question 1

A pattern is failing to map a specific attribute because the command used returns multi-line output. What is the standard way to handle this in a Discovery Pattern?

Accepted Answer

Use a 'Parse' step with a Regular Expression (Regex) to extract the specific value.. Patterns use parsing steps (like Regex or Split) to convert multi-line output into structured attribute data.

Answer

Use a MID Server script file to process the output.

Answer

Ignore the attribute.

Answer

Change the command to only return a single line.

Question 2

What is the purpose of a 'Discovery Source' in the CMDB?

Accepted Answer

To identify which tool or process created or updated the CI record.. The 'Discovery Source' field identifies which tool (Discovery, Service Mapping, SCCM, etc.) populated or last updated the CI record.

Answer

To store the last successful login time.

Answer

To specify which MID server is authorized to access the CI.

Answer

To define which credentials should be used for a scan.

Question 3

Which action should you perform before modifying a default Discovery Pattern?

Accepted Answer

Create a copy of the pattern.. To avoid losing changes during upgrades, you must make a copy of the pattern before modification.

Answer

Export the pattern to an XML file.

Answer

Reboot the MID server.

Answer

Delete the original pattern.

Question 4

You are migrating from legacy horizontal discovery to Service Mapping. How should you handle the transition of existing CMDB CI relationships?

Accepted Answer

Ensure existing CIs have stable identification attributes so Service Mapping can build on them.. Service Mapping relies on existing identification rules; existing relationships should be verified for consistency.

Answer

Create a new CMDB class for all Service Mapping CIs.

Answer

Force all CIs to be re-discovered by the same MID server.

Answer

Delete all existing relationships before starting.

Question 5

Which module allows you to visualize the dependencies and connections between CIs in a map view?

Accepted Answer

Dependency View. The Dependency View is the standard ServiceNow interface for visualizing CI relationships.

Answer

CMDB Query Builder

Answer

Discovery Status

Answer

Business Service Map

Question 6

When a CI record is 'Orphaned' according to the CMDB Health Dashboard, what does this mean?

Accepted Answer

The CI has no relationships to other CIs.. An Orphan CI is a CI that has no incoming or outgoing relationships, which is often unexpected for core infrastructure components.

Answer

The CI has no identified owner.

Answer

The CI is not associated with an Asset.

Answer

The CI has not been scanned for over 30 days.

Question 7

You notice that the 'Last Discovered' field is not updating, even though the Discovery schedule runs successfully. What is the first thing you should check?

Accepted Answer

Check the Identification and Reconciliation Engine (IRE) logs.. The 'Last Discovered' field is updated by the Discovery process; if it isn't updating, the process may be failing at the Identification stage.

Answer

Check the MID server's CPU usage.

Answer

Update the Discovery Pattern definition.

Answer

Verify the network connectivity to the targets.

Question 8

What is the primary role of the Identification and Reconciliation Engine (IRE) in the Discovery process?

Accepted Answer

To ensure data integrity and prevent CI duplication.. The IRE acts as a gatekeeper to ensure that only valid, non-duplicate, and authorized data is written to the CMDB.

Answer

To execute discovery probes on target devices.

Answer

To monitor the status of MID servers.

Answer

To map business services based on traffic data.

Question 9

You have a situation where a CI is being updated, but you don't know which data source is responsible. Where can you look to find the authoritative source for each attribute?

Accepted Answer

CMDB Reconciliation Rules. Reconciliation rules allow an administrator to define which sources are permitted to update specific CI attributes.

Answer

CI relationship graph

Answer

Discovery schedule settings

Answer

Discovery log

Question 10

Which of the following best describes the purpose of 'CMDB Data Manager'?

Accepted Answer

To automate the lifecycle management of CIs.. CMDB Data Manager is used for automating the lifecycle management of CIs, such as retiring or deleting them.

Answer

To map IP addresses to subnets.

Answer

To manage MID server credentials.

Answer

To generate reports on CI count.

Question 11

What is the purpose of the 'discovery_id' in a discovery log?

Accepted Answer

To uniquely identify a specific Discovery scan execution.. The discovery_id (or status ID) is a unique identifier for a specific Discovery scan execution, used for troubleshooting.

Answer

To identify the user who triggered the scan.

Answer

To link the device to a specific MID server.

Answer

To mark the CI as 'Discovered'.

Question 12

When a discovery pattern finishes, it creates an 'Identification' payload. Where is this payload processed?

Accepted Answer

Identification and Reconciliation Engine (IRE). The payload is sent to the Identification and Reconciliation Engine (IRE) for processing against the CMDB.

Answer

Discovery Status table

Answer

MID Server

Answer

CMDB CI table

Question 13

What is the primary function of the 'CI Class Manager'?

Accepted Answer

To manage class hierarchy, identification, and reconciliation rules.. CI Class Manager is the centralized UI for managing class hierarchy, identification rules, and reconciliation rules.

Answer

To monitor network traffic.

Answer

To create new Discovery users.

Answer

To update Discovery patterns.

Question 14

You are creating a custom CI class. Which step is essential to ensure that Discovery can identify CIs of this new class?

Accepted Answer

Define an Identification Rule for the new class.. You must create an Identification Rule for the new class, otherwise the system won't know how to handle incoming discovery data for it.

Answer

Add the class to the global discovery schedule.

Answer

Assign a default MID server.

Answer

Publish the class to the Service Catalog.

Question 15

If Discovery cannot find a pattern for an OS version, what does the system typically do?

Accepted Answer

The discovery process for that device fails or remains incomplete.. If no pattern is found, Discovery may fall back to a classification probe or simply stop discovery for that specific device depending on the configuration.

Answer

It automatically creates a generic Linux CI.

Answer

It creates a dummy CI record.

Answer

It uses the last used pattern.
