SERVICENOW-CIS-DISCOVERY Discovery Pattern Design Practice Test 4 — 15 Questions

Question 1

Which TWO of the following can be configured in a Pattern step?

Accepted Answer

Run as (user privilege). Steps include configurations for command execution and error handling.

Answer

User password rotation

Answer

MID Server selection

Answer

CI Class Manager update

Question 2

Which THREE things must be true for a pattern to successfully populate an attribute?

Accepted Answer

The target attribute must exist on the CI class. The data must be captured, mapped, and the target CI must be valid.

Answer

The pattern must be running as administrator

Answer

The pattern must be in English

Question 3

Which TWO of the following are valid ways to debug a pattern?

Accepted Answer

Review the 'Pattern Log' in the Discovery Status. You can use the debugger with saved status data or preview the output in the step.

Answer

Restart the instance

Answer

Modify the MID Server source code

Answer

Run the pattern from the command line

Question 4

Which THREE actions occur when a pattern is published?

Accepted Answer

The pattern moves from 'Draft' to 'Active'. Publication makes the pattern active, allows it to be used by discovery, and saves a version.

Answer

The MID server is restarted

Answer

The pattern is deleted

Question 5

Which TWO of the following are key components of the Pattern Designer?

Accepted Answer

Debug panel. The designer consists of the step palette and the execution/debug environment.

Answer

Update Set Manager

Answer

CMDB Health dashboard

Answer

CI Class Manager

Question 6

Which THREE parsing methods are available in the 'Parse' step?

Accepted Answer

JSON. The Parse step supports several formats including JSON, XML, and Regex.

Answer

JavaScript

Answer

SQL

Question 7

Which TWO of the following are considered 'best practices' for pattern design?

Accepted Answer

Add comments to steps to describe logic. Keeping patterns modular and documenting the steps are essential practices.

Answer

Hardcode all credentials in the pattern

Answer

Create one giant section for everything

Answer

Never use variables

Question 8

Which THREE options are available when creating a 'New Step'?

Accepted Answer

Parse. Steps can be chosen from the palette, such as command, parsing, or flow control.

Answer

Database Update

Answer

Report

Question 9

Which THREE of the following are valid ways to handle command output in a pattern?

Accepted Answer

Parse it with regex. You can parse it, store it in a variable, or use it as a trigger for conditional logic.

Answer

Delete it from the MID Server

Answer

Email it to the admin

Question 10

Which TWO of the following are valid CI relationship types that can be created in a pattern?

Accepted Answer

Runs on. Patterns support standard CMDB relationships like 'Runs on' or 'Depends on'.

Answer

Owned by

Answer

Created by

Answer

Updated by

Question 11

Which TWO scenarios indicate that an identification rule is misconfigured?

Accepted Answer

The system creates duplicate CIs for the same asset. If multiple CIs are created when one should exist, or if updates are applied to the wrong CI, the rules are likely wrong.

Answer

The pattern takes too long to run

Answer

The CMDB is full

Answer

The MID server service is stopped

Question 12

You are creating a custom pattern to identify a new type of load balancer. You need to verify that the identification section correctly maps the serial number to the cmdb_ci_lb_device table. Which debugging tool within the Pattern Designer should you use to validate the identification section without running a full Discovery schedule?

Accepted Answer

Pattern Debugger. The 'Debug' button within the Pattern Designer allows users to execute individual sections of a pattern against a specific MID Server and IP address to validate output variables and identification logic.

Answer

Identification Reconciliation Engine (IRE) Log

Answer

ECC Queue Monitor

Answer

Discovery Log

Question 13

When parsing a configuration file using the 'Text' parser, which configuration setting is required to define how the parser should handle multi-line blocks where key-value pairs are separated by colons?

Accepted Answer

Line Delimiter. The Delimiter and block parsing settings are required to correctly identify the structure of the text file.

Answer

JSON Path

Answer

Regex Pattern

Answer

Variable Mapping

Question 14

You are writing a pattern that requires data from a REST API endpoint that returns a nested JSON array. Which step type is most appropriate to extract a specific attribute from an object located at the third index of the nested array?

Accepted Answer

Parse JSON. The 'Parse JSON' step allows for the use of JSONPath, which is the standard way to traverse complex, nested JSON structures in ServiceNow patterns.

Answer

Table Transformation

Answer

Set Variable

Answer

Regex Extraction

Question 15

If you need to extend an existing pattern for a network switch, which action ensures that your custom logic is executed during the Discovery process while maintaining the original functionality?

Accepted Answer

Create an Extension Section. The 'Extension Section' is the designated feature for adding custom logic to an existing pattern without modifying the base, OOB pattern steps.

Answer

Override the CI Class

Answer

Create a new Discovery Schedule

Answer

Modify the Base Pattern directly
