SERVICENOW-CIS-DISCOVERY Practice Test 15 — 15 Questions

Question 1

Which THREE of the following are key components for configuring a successful Discovery?

Accepted Answer

MID Server. Schedules, MID Servers, and Credentials are the foundational blocks for any discovery project.

Answer

Knowledge Base

Answer

Incident Management

Question 2

Which TWO of the following are true regarding the Shazzam phase?

Accepted Answer

It is used to identify which ports are open. Shazzam is the first phase and is used to identify which ports are open on discovered IPs.

Answer

It gathers detailed CI attributes

Answer

It updates the CMDB directly

Answer

It performs credential validation

Question 3

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 4

After an upgrade, several CIs are showing as 'Orphaned'. What does this status imply in the context of CMDB Health?

Accepted Answer

The CI has no relationship to any other CI in the CMDB.. An orphaned CI is a CI that has no relationship to other CIs or that is not correctly linked to the business service topology as defined.

Answer

The CI belongs to a class that is no longer supported.

Answer

The CI was discovered by a decommissioned MID Server.

Answer

The CI has no parent class.

Question 5

You need to add a new CI type to an existing horizontal pattern. Which step must be performed in the Pattern Designer to ensure the CI is linked to the parent process?

Accepted Answer

Use the 'Related CI' step within the Identification section.. To link a CI to a parent process in a pattern, you must define the relation in the Identification section using the 'Related CI' step.

Answer

Add a new CI entry in the 'Identification Rules' table.

Answer

Modify the 'Discovery CI Identification' business rule.

Answer

Create a new pattern definition record in the CMDB.

Question 6

Which of the following is the correct order of operations in a horizontal pattern?

Accepted Answer

Identification, Connection, Extension. The standard flow is Identification, then Connection, then Extension sections.

Answer

Connection, Identification, Extension

Answer

Identification, Extension, Connection

Answer

Extension, Identification, Connection

Question 7

Which TWO of the following are valid ways to configure an IP range for a Discovery Schedule?

Accepted Answer

CIDR notation. Discovery supports both CIDR notation and start/end IP ranges.

Answer

Subnet mask

Answer

Wildcard ranges (e.g., 10.1.*.*)

Answer

Comma-separated list of Hostnames

Question 8

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 9

A Discovery run is successfully finding CIs, but the 'CMDB Health Dashboard' shows 'Staleness' errors. What is the primary cause of staleness in the CMDB?

Accepted Answer

The CI has not been updated by a discovery source within the defined threshold.. Staleness occurs when a CI's 'Last discovered' date is older than the threshold defined in the CMDB Health configuration.

Answer

The discovery credentials have expired.

Answer

The CI record has duplicate attributes.

Answer

The CI is not associated with any Discovery Schedule.

Question 10

A complex environment requires that two different Discovery sources (e.g., ServiceWatch and a third-party tool) populate the same CI attributes. How can you ensure the third-party tool's data is preferred over Discovery for specific attributes?

Accepted Answer

Set the third-party data source priority to 100 and discovery to 200.. Reconciliation Rules assign a priority value to data sources; the highest priority source wins the attribute update.

Answer

Disable 'Discovery' in the CI Class identification rule.

Answer

Use a Business Rule to intercept the discovery payload.

Answer

Set the discovery source priority to 100 and the third-party source to 200.

Question 11

When using the 'Parse Delimited' step, what is the 'Separator' attribute used for?

Accepted Answer

To define the character that splits the data fields.. The separator defines the character (e.g., comma, pipe) that splits the columns in the text.

Answer

To define the row identifier.

Answer

To identify the end of the file.

Answer

To escape special characters.

Question 12

What does the 'Debug' mode in the Pattern Designer require to function?

Accepted Answer

A selected Discovery status record (node).. Debug mode requires a target node to execute the pattern against, which is provided by a Discovery status record.

Answer

A new CI class.

Answer

A valid user session.

Answer

The MID Server to be in debug mode.

Question 13

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 14

Where can you find a summary of the total number of CIs discovered versus those updated, identifying potential efficiency issues in your Discovery infrastructure?

Accepted Answer

Discovery Dashboard. The Discovery Dashboard provides metrics on CIs discovered, updated, and failed during a discovery run.

Answer

Service Mapping dashboard

Answer

CMDB Health Dashboard

Answer

MID Server dashboard

Question 15

Which THREE of the following are valid sources for the Identification and Reconciliation Engine (IRE)?

Accepted Answer

Service Graph Connectors. The IRE is agnostic to the source, and data can come from Discovery, Service Graph Connectors, or manual imports.

Answer

System Logs

Answer

Manual CI creation via UI
