SERVICENOW-CIS-DISCOVERY Practice Test 2 — 25 Questions

Question 1

What is the status of a newly installed MID Server that has not yet been validated?

Accepted Answer

Validation Required. New MID servers require validation by an admin before they are trusted to perform work.

Answer

Validated

Answer

Down

Answer

Up

Question 2

Which functionality allows a pattern to call another pattern, thereby promoting modularity and reuse of common identification logic?

Accepted Answer

Call Pattern step. The 'Call Pattern' step in ServiceNow Pattern Designer allows one pattern to invoke another pattern as a subroutine, passing inputs and receiving outputs. This enables modular design where common identification logic (e.g., Linux hostname parsing) is defined once and reused across multiple patterns.

Answer

Pattern Inheritance

Answer

Pattern Extension

Answer

Global Function Library

Question 3

Which TWO of the following are true about the 'Discovery Status' module?

Accepted Answer

It provides detailed phase-by-phase information. It provides a historical log of all discovery runs and detailed information about what occurred during each phase.

Answer

It is the only place to define IP ranges

Answer

It automatically fixes CMDB errors

Answer

It is used to manage credentials

Question 4

What is the purpose of 'Discovery' patterns?

Accepted Answer

To populate the CMDB with CI data.. Discovery patterns are used to populate the CMDB with CI data from infrastructure components.

Answer

To generate incident reports.

Answer

To manage user access.

Answer

To create business services.

Question 5

What is the effect of setting 'mid.log.level' to 'debug' in the agent.config file?

Accepted Answer

It provides more detailed troubleshooting information in the agent logs. Setting the log level to debug increases the granularity of the logs, useful for troubleshooting, but generates large files.

Answer

It increases the polling speed

Answer

It enables automatic error reporting

Answer

It forces the MID Server to re-validate

Question 6

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 7

Which UI tool is used to visualize the pattern execution flow?

Accepted Answer

Pattern Designer. The Pattern Designer includes a graphical interface that displays the steps and flow of the pattern.

Answer

Discovery Dashboard

Answer

Service Mapping view

Answer

CI Class Manager

Question 8

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 9

You need to ensure that a specific MID Server only performs WMI discovery and ignores SSH tasks. How do you configure this?

Accepted Answer

Assign only the 'WMI' capability in the 'Capabilities' related list. Capabilities are used to restrict the types of tasks a MID Server will accept. Removing the SSH capability ensures the MID Server ignores those jobs.

Answer

Create an Access Control List (ACL) on the ECC Queue

Answer

Set the 'Discovery Source' field to 'WMI'

Answer

Modify the 'Supported Protocols' field on the MID Server record

Question 10

When a pattern step fails, how can you determine which step caused the failure?

Accepted Answer

Review the Discovery Status record log.. The Discovery status log shows the step that failed in the execution flow.

Answer

Re-run the Discovery as admin.

Answer

Check the MID Server service.

Answer

Look at the CMDB class manager.

Question 11

What is the primary function of the 'MID Server' application in ServiceNow?

Accepted Answer

To act as a gateway for communication between the instance and the local network. The MID Server acts as a bridge between the instance and the internal network for data collection.

Answer

To handle user authentication

Answer

To replace the need for firewalls

Answer

To store all network data

Question 12

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. Encrypted credentials in ServiceNow Discovery rely on credential aliases that must be explicitly associated with the MID Server or its MID Server policy. If the alias is not linked, the MID Server cannot decrypt or use the credential, causing authentication failures. This is the most common configuration oversight when encrypted credentials fail.

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 13

A MID Server reports 'Up' but is not processing any jobs. What is the most likely cause?

Accepted Answer

The MID Server is paused. If a MID Server is paused, it will remain up but will not poll for work from the ECC Queue.

Answer

The MID Server is in a cluster

Answer

The MID Server is not validated

Answer

The MID Server is missing the 'Discovery' capability

Question 14

What is the purpose of the 'MID Server Properties' module?

Accepted Answer

To manage global configuration properties for all MID Servers. This module allows you to define system-wide properties that influence all MID Servers.

Answer

To define individual server IP addresses

Answer

To store user passwords

Answer

To list all discovery jobs

Question 15

Which of the following best describes how the CMDB Health Dashboard defines 'Duplicate' CIs?

Accepted Answer

Multiple CIs that share the same identification criteria.. Duplicates are identified based on multiple CIs matching the same criteria defined in the Identification Rules.

Answer

CIs with the same name.

Answer

CIs discovered at the same time.

Answer

CIs that share the same IP address.

Question 16

When a pattern step needs to run as root, where is this configuration set?

Accepted Answer

In the step properties, 'Run as' field.. The 'Run as' field in the step properties allows you to specify the execution context (e.g., sudo/root).

Answer

In the MID Server property.

Answer

In the Discovery Schedule.

Answer

This cannot be done in a pattern.

Question 17

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 18

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 19

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 20

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
