SERVICENOW-CIS-DISCOVERY Practice Test 5 — 25 Questions

Question 1

You are troubleshooting a MID Server that is stuck in the 'Validated' state but not picking up jobs. You notice the 'MID Server Issues' list reports a 'Clock drift' error. What is the recommended resolution?

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

Accepted Answer

Synchronize the MID Server host time with an NTP server. Clock drift indicates the MID Server host time is out of sync with the instance, causing authentication issues with the ECC Queue.

Answer

Update the 'MID Server' record to 'Down' and back to 'Up'

Answer

Increase the 'ECC Queue' processing timeout

Answer

Restart the MID Server service

Question 2

If a MID Server is configured to use an encrypted credential but it is failing, what is the most likely cause?

Accepted Answer

The credential alias is not associated with the MID Server or its policy. The credential might be missing the appropriate scope or the MID server might not have the rights to use that specific credential alias.

Answer

The MID Server is running on Windows

Answer

The MID Server is not in a cluster

Answer

The MID Server needs to be restarted

Question 3

A Discovery scan successfully identifies a Linux server, but the 'Operating System' field is not being updated in the CMDB. You have verified that the pattern correctly extracts the OS version. What is the most likely configuration issue?

Accepted Answer

A Reconciliation Rule exists that prevents the 'ServiceNow' data source from updating the 'Operating System' attribute.. Data source reconciliation rules determine which data sources have update authority for specific fields.

Answer

The CI class is marked as 'Read Only' in the CMDB dashboard.

Answer

The Discovery schedule is using the wrong MID server.

Answer

The Linux pattern is not published to the production environment.

Question 4

An administrator wants to ensure that data imported from an external asset system does not overwrite data collected by Discovery. How should this be configured?

Accepted Answer

Configure Reconciliation Rules to grant Discovery higher priority for those attributes.. Reconciliation rules allow you to specify which data sources are authoritative for specific CI attributes.

Answer

Change the CI class to read-only.

Answer

Use an Import Set Transform Map script to check the source.

Answer

Disable the external import integration.

Question 5

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 6

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 7

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 8

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 9

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 10

You need to ensure that Discovery data from a third-party integration does not overwrite manual updates made by the IT team in the CMDB. Which feature should you configure?

Accepted Answer

Reconciliation Rules. Reconciliation Rules define which data sources are allowed to update specific attributes of a CI.

Answer

CMDB Transform Maps

Answer

Discovery Access Control Lists (ACLs)

Answer

Data Preserver

Question 11

You are creating a new Discovery pattern and need to extract data from a command output where lines are separated by a consistent delimiter. Which parsing strategy should you use to map these specific values to table attributes?

Accepted Answer

Delimited parsing. The Delimited parsing strategy is specifically designed for structured text outputs where fields are separated by characters like commas, tabs, or pipes.

Answer

JSON parsing

Answer

XML parsing

Answer

Regex parsing

Question 12

You want to run a command only if a previous step was successful. How is this configured?

Accepted Answer

Using a 'Pre-condition' on the step.. You can use the 'Condition' field on a step to check the state of previous steps.

Answer

This is not possible.

Answer

Using an Extension section.

Answer

Using a 'Wait' step.

Question 13

Which of the following parsing strategies is best for a response formatted as a list of key-value pairs separated by equal signs?

Accepted Answer

Name-Value pair parsing. The Name-Value pair parser is specifically designed for such formats.

Answer

Delimiter parsing

Answer

Regex

Answer

JSON parsing

Question 14

Which TWO actions should you perform to maintain the integrity of the CMDB when a CI is decommissioned?

Accepted Answer

Update the 'Operational status' field to 'Retired'.. To properly retire a CI, you must update its status and ensure it no longer appears in active discovery processes.

Answer

Delete the CI record from the database.

Answer

Clear the 'Last discovered' field.

Answer

Change the CI class to 'Archive'.

Question 15

If you want to ensure that a Discovery Schedule runs exactly once every 24 hours starting at a specific time, which setting do you use?

Accepted Answer

Run: Daily. Setting the 'Run' field to 'Daily' allows you to define the start time and frequency.

Answer

Run: On Demand

Answer

Run: Periodically

Answer

Run: Weekly

Question 16

If you need to ensure that a Discovery scan does not impact network traffic, what is a recommended best practice?

Accepted Answer

Distribute discovery scans across multiple schedules and MID servers.. Staggering discovery schedules and using IP ranges to distribute the load across time and MID servers is the standard practice.

Answer

Set the discovery to run at night.

Answer

Disable the Shazzam phase.

Answer

Limit the scan to one IP per hour.

Question 17

What is the consequence of having an incorrect 'Identification Rule' for a hardware CI class?

Accepted Answer

Discovery may create duplicate CI records for the same physical hardware.. Incorrect rules lead to either duplicate CI records or 'flapping' (repeatedly updating the wrong CI).

Answer

Discovery will stop scanning the network.

Answer

The CMDB Health Dashboard will automatically fix the rules.

Answer

The MID server will lose its credentials.

Question 18

Which component is responsible for orchestrating the flow of CI data from the discovery source to the CMDB, ensuring data quality?

Accepted Answer

Identification and Reconciliation Engine (IRE). The Identification and Reconciliation Engine (IRE) orchestrates all incoming CI data to ensure it adheres to CMDB rules.

Answer

MID Server

Answer

Discovery Pattern

Answer

CMDB Health Dashboard

Question 19

What is the purpose of an 'IP Service' in Discovery?

Accepted Answer

To define a set of ports and protocols for scanning.. IP Services group ports and protocols together for use in port scanning, making it easier to define what to scan.

Answer

To assign a MID Server.

Answer

To define the IP range.

Answer

To provide credentials.

Question 20

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