SERVICENOW-CIS-DISCOVERY CMDB Integration And Maintenance Practice Test 4 — 15 Questions

Question 1

When a discovery pattern finishes, which log should you review to see the raw payload output that was sent to the IRE?

Accepted Answer

Discovery Log. The 'Discovery Log' within the Discovery Status record shows the sequence of events, and the 'Payload' tab or related list shows what was sent to the IRE.

Answer

MID Server log

Answer

CMDB Health Dashboard

Answer

System Log

Question 2

You need to ensure that a specific attribute is NOT updated by any source except a manual update from a specific user group. How can this be done?

Accepted Answer

Set the Reconciliation rule for that attribute to only allow the 'Manual' data source.. Reconciliation rules allow you to specify data sources, but for non-Discovery sources, ACLs or Data Policies might be used; however, in terms of reconciliation, you can define a 'None' rule or manage it via source priority.

Answer

Change the class to 'Internal'.

Answer

Remove the attribute from the discovery pattern.

Answer

Create a business rule that runs after insert/update.

Question 3

Which of the following is the most effective way to view the relationships of a CI in a graphical format?

Accepted Answer

Dependency View. The Dependency View is the standard graphical interface for viewing CI relationships in ServiceNow.

Answer

CMDB Health Dashboard

Answer

List View

Answer

Discovery Status

Question 4

When a Discovery pattern step fails due to a timeout, what is the best approach to fix it?

Accepted Answer

Increase the timeout value in the pattern step settings.. Timeouts often occur because the command is too slow. You can increase the timeout setting in the specific pattern step or optimize the command.

Answer

Change the Discovery schedule to run at night.

Answer

Delete the step.

Answer

Increase the MID server memory.

Question 5

What is the primary benefit of using the CMDB Health Dashboard?

Accepted Answer

To identify and report on data quality issues in the CMDB.. The dashboard provides visibility into data quality, helping admins identify areas that need attention.

Answer

To manage server patches.

Answer

To configure MID server credentials.

Answer

To create new CI relationships.

Question 6

Which of the following is a common symptom of a 'stale' CI?

Accepted Answer

The CI has not been updated by discovery within the expected timeframe.. A stale CI is one that hasn't been updated recently, suggesting it might be retired or the discovery scan is failing.

Answer

The CI has a duplicate.

Answer

The CI has too many relationships.

Answer

The CI is missing required attributes.

Question 7

Which of the following is true regarding the relationship between Discovery and the CMDB?

Accepted Answer

Discovery acts as a data source that the IRE processes into the CMDB.. Discovery is one of many data sources that can populate the CMDB, and it relies on the IRE to process its findings.

Answer

The CMDB informs Discovery what to scan.

Answer

Discovery and the CMDB are the same application.

Answer

Discovery directly writes to the CMDB tables.

Question 8

In the context of the CMDB, what does 'Orphan' refer to?

Accepted Answer

A CI with no relationships to other CIs.. An 'Orphan' CI is a CI that lacks any relationships to other CIs, which is often an indication of an incomplete CMDB model.

Answer

A CI with no owner.

Answer

A CI that has not been scanned.

Answer

A CI created by a guest user.

Question 9

You are implementing a new discovery tool and want to ensure it integrates seamlessly with existing CMDB identification rules. What is the first step?

Accepted Answer

Review existing Identification Rules to ensure they support the new tool's incoming CI data.. You must check existing Identification Rules to see if the new tool's data can be mapped using existing identifiers.

Answer

Delete all existing CIs.

Answer

Disable all existing identification rules.

Answer

Use a new CI class for all data from the new tool.

Question 10

What happens in the CMDB when a 'Reconciliation Rule' identifies a conflict between two data sources?

Accepted Answer

The data source with the higher priority value updates the CI attribute.. The rule determines which source 'wins' based on the priority value assigned to the data sources; the loser is ignored for that attribute.

Answer

The system automatically creates a new CI.

Answer

The system prompts the user to choose.

Answer

Both values are stored as an array.

Question 11

If you need to define a new CI attribute that should be populated by Discovery, which task is mandatory?

Accepted Answer

Ensure the Reconciliation Rule allows the 'Discovery' data source to write to the new attribute.. If Discovery is to populate the attribute, you must add it to the pattern and ensure that no Reconciliation Rule prevents the 'Discovery' data source from writing to it.

Answer

Make the attribute 'Mandatory' in the dictionary.

Answer

Create a new CI class.

Answer

Add the attribute to the 'Discovery' schedule.

Question 12

Which of the following describes the purpose of the 'CI Class Manager'?

Accepted Answer

To manage class hierarchy and CI rules.. It provides a centralized interface for managing the configuration of all CI classes, including identification and reconciliation rules.

Answer

To manage user roles.

Answer

To perform network vulnerability scans.

Answer

To schedule Discovery jobs.

Question 13

You are configuring a Discovery CI identification rule for Linux servers and notice that multiple CIs are being created for the same physical device. Which component should you verify to ensure the Identification Engine correctly links the incoming data to an existing CI?

Accepted Answer

Identification Rule. The Identification Engine uses Identification Rules to compare attributes to determine if a CI exists. If these rules are misconfigured, duplicates occur.

Answer

Discovery Schedule

Answer

Discovery Pattern

Answer

Data Source

Question 14

A technician reports that Discovery is updating the 'Last discovered' field, but the 'Operational status' is not changing as expected. Where should you investigate the mapping of Discovery data to the CMDB?

Accepted Answer

Identification and Reconciliation Engine (IRE) Data Source Rules. The CMDB CI Class Models and the mapping configuration in the pattern or identification rule define how attributes are populated.

Answer

Discovery Log

Answer

CMDB Data Manager

Answer

Discovery Dashboard

Question 15

You are troubleshooting a scenario where Discovery is creating a new CI instead of updating an existing one. You have verified the serial number is correctly identified. What is the most likely cause within the Identification Rule?

Accepted Answer

The 'Required' checkbox is unchecked for the Serial Number attribute in the Identifier Entry.. If the identification rule has 'Required' fields that do not match the incoming payload, the IRE cannot successfully match the existing CI.

Answer

The CI Class is not in the Discovery Schedule.

Answer

The 'Sync' flag is disabled in the Discovery Schedule.

Answer

The Discovery Pattern is set to 'Create' mode.
