SERVICENOW-CIS-DISCOVERY Quick Quiz — 10 Questions

Question 1

When a pattern step uses a 'Query' to the target, what is the 'Temporary Variable' used for?

Accepted Answer

To store the output of the step for use in subsequent steps.. A temporary variable is used to store the output of a pattern step so that subsequent steps can access and parse that data.

Answer

To act as a filter for the result set.

Answer

To increase the speed of the scan.

Answer

To define the credentials for the query.

Question 2

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 3

Which THREE actions should you take when troubleshooting a discovery process that is failing to populate the 'Serial Number' field for a specific class of routers?

Accepted Answer

Review the Identification Rule for the router class. Troubleshooting involves verifying the pattern execution, the identification rule logic, and the reconciliation rule settings.

Answer

Increase the Discovery timeout value

Answer

Modify the MID Server cluster configuration

Question 4

When configuring Data Sources for CMDB reconciliation, which TWO of the following are true regarding the behavior of the Identification and Reconciliation Engine (IRE)?

Accepted Answer

Data source importance determines which source takes precedence during a reconciliation conflict.. The IRE uses source priority and data source configuration to manage conflicting attribute data.

Answer

Custom data sources require a new Identification Rule for every CI class.

Answer

IRE ignores data sources that are not explicitly defined in the Identification Rules.

Answer

Discovery always has higher priority than manual CMDB updates by default.

Question 5

Where can you see the 'Discovery Log' for a specific device that was scanned?

Accepted Answer

In the Discovery Status record.. The Discovery Status record contains a related list for 'Discovery Log' which shows all messages for that scan run.

Answer

In the CMDB CI record.

Answer

In the MID Server dashboard.

Answer

In the System Log.

Question 6

You are troubleshooting a scenario where Discovery is creating duplicate CIs for the same server. Which table should you inspect to verify the Identification Rule settings for the specific CI class?

Accepted Answer

cmdb_identifier_entry. The cmdb_identifier_entry table defines the attributes used to uniquely identify a CI, which prevents duplicates.

Answer

discovery_device_history

Answer

sys_reconciliation_rule

Answer

cmdb_ci_relation

Question 7

Which ServiceNow feature allows you to visualize the flow of data from Discovery into the CMDB, helping to debug why a CI attribute was populated with a specific value?

Accepted Answer

CI Identification and Reconciliation (IRE) logs. The 'CMDB Workspace' or 'CI Identification and Reconciliation' logs allow you to see the payload sent to the IRE.

Answer

System Logs

Answer

Discovery Pattern Designer

Answer

Discovery Home Page

Question 8

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 9

Which THREE of the following are components or features that are part of the 'Discovery' to 'CMDB' data pipeline?

Accepted Answer

Discovery Patterns. The pipeline includes data collection (Discovery), processing (IRE), and governance (Reconciliation).

Answer

Incident Management

Answer

Knowledge Management

Question 10

A customer requires that a specific Discovery Schedule only executes during maintenance windows on weekends. Which configuration setting should be modified?

Accepted Answer

Adjust the 'Run' field to 'Periodically' and select a custom Schedule record.. The Schedule field on the Discovery Schedule record defines the execution frequency using standard system schedules.

Answer

Change the discovery pattern logic.

Answer

Update the Discovery Behavior record.

Answer

Modify the MID Server cluster affinity.
