SERVICENOW-CIS-DISCOVERY Practice Test 8 — 10 Questions

Question 1

When dealing with a nested XML response from an API, which parsing method should be used to drill down into a specific child node?

Accepted Answer

Parse XML with XPath. The 'Parse XML' step supports XPath, which is ideal for traversing nested XML structures.

Answer

Parse Delimited Text

Answer

Parse JSON

Answer

Parse Name-Value pair

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 'Library' feature (shared patterns) or calling sub-patterns allows for modular code reuse in Discovery.

Answer

Pattern Inheritance

Answer

Pattern Extension

Answer

Global Function Library

Question 3

Which TWO steps are essential for parsing a command output that contains key-value pairs formatted as 'key = value'?

Accepted Answer

Define the Line Delimiter. For key-value parsing, identifying the line delimiter and the key-value separator is essential.

Answer

Execute an external shell script

Answer

Convert the output to XML

Answer

Apply a JSON Path

Question 4

You are parsing a multi-line string containing key-value pairs separated by colons. Which tool is most appropriate for a single step extraction?

Accepted Answer

Parse Name-Value pair. The 'Parse Name-Value pair' step is designed to automatically extract multiple key-value pairs from a text block.

Answer

Regex

Answer

Parse Delimited

Answer

XPath

Question 5

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 6

In a horizontal pattern, you have an Identification section that fails to match a CI. What is the most likely cause if the 'Identification' step has correct attributes?

Accepted Answer

The Identification rule does not support the CI class.. If attributes are correct, the 'Identification Rule' or 'CI Type' settings are usually the culprit for mismatches.

Answer

The pattern contains syntax errors.

Answer

The Discovery credentials are invalid.

Answer

The pattern is not published.

Answer

The MID Server is down.

Question 7

Which of the following is true about 'Identification Sections'?

Accepted Answer

They must be the first section in the pattern.. An identification section must contain at least one step that identifies the CI.

Answer

They are optional.

Answer

They don't support regex.

Answer

They can only be used once per pattern.

Question 8

What should you check to see if a MID Server has successfully completed a job?

Accepted Answer

The ECC Queue list. The ECC Queue output and input messages for that job will show status and returned data.

Answer

The Discovery Dashboard

Answer

The MID Server log

Answer

The MID Server Properties

Question 9

When using 'Parse JSON' for a complex structure, how do you access a nested property named 'id' inside an array 'servers'?

Accepted Answer

servers[0].id. You use dot-notation (or specific path syntax) to navigate the JSON structure.

Answer

servers->id

Answer

servers.id

Answer

id(servers)

Question 10

You need to store the result of a WMI query in a variable that can be accessed across different sections of the pattern. Which step type should you use?

Accepted Answer

Set Variable. The 'Set Variable' step allows you to capture output from previous steps and assign it to a variable that persists throughout the pattern execution.

Answer

Parse JSON

Answer

Table Transformation

Answer

Registry Extraction
