SERVICENOW-CIS-DISCOVERY Practice Test 3 — 30 Questions

Question 1

Which of the following is NOT a required part of a Discovery Schedule?

Accepted Answer

Excluded IP Range.. While many fields exist, an 'Excluded IP Range' is optional, whereas target IP ranges and MID servers are fundamental.

Answer

Target IP Range.

Answer

MID Server.

Answer

Discovery Behavior.

Question 2

Which TWO of the following are primary functions of a Discovery Behavior?

Accepted Answer

Assigning specific probes to a schedule. Behaviors dictate which probes to use and can be used to define customized sets of exploration tasks.

Answer

Defining the target IP address range

Answer

Managing MID Server credentials

Answer

Scheduling the discovery job

Question 3

During the Identification phase, you notice that multiple CI records are being created for the same physical server. Which component should you verify to ensure the Identification engine correctly merges these attributes?

Accepted Answer

Identification Rules. Identification Rules define the criteria used by the Identification and Reconciliation Engine (IRE) to determine if a CI already exists, preventing duplicates.

Answer

Classification Criteria

Answer

Discovery Patterns

Answer

Discovery Probes

Question 4

Which THREE of the following are valid ways to improve discovery performance?

Accepted Answer

Using a MID Server cluster for load balancing. Parallel processing, clustering, and targeting smaller, frequent ranges all improve efficiency.

Answer

Disabling all classifiers

Answer

Running all discoveries at once

Question 5

A discovery scan is failing during the Exploration phase because the credentials are insufficient. Where should you look to find the specific error logs related to this credential failure?

Accepted Answer

The Discovery Log. The Discovery Log (Discovery > Discovery Log) captures status and error messages from all phases, including credential failures encountered during Exploration.

Answer

The Workflow Context

Answer

The ECC Queue

Answer

The MID Server Issue record

Question 6

Which of the following describes the function of the 'Discovery' section in a pattern?

Accepted Answer

It executes commands to gather data from the target.. The discovery section is where actual commands are executed on the host.

Answer

It defines the connection to the target.

Answer

It creates the CI record.

Answer

It maps attributes to the CMDB.

Question 7

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

Answer

Answer

Question 8

When using the 'Parse Variable' step to extract data, which component is required to capture a specific substring from a larger variable using a capture group?

Accepted Answer

Regular Expression. A Regular Expression (Regex) with parentheses for capture groups is the correct method to extract specific data from a string variable.

Answer

Delimited Parsing

Answer

XML Path

Answer

JSONPath

Question 9

What happens if you have two MID Servers with the same name?

Accepted Answer

The MID Server will fail to register correctly. Naming collisions in MID Servers cause registration failures or erratic behavior as they attempt to update the same record.

Answer

They load balance automatically

Answer

The instance will merge them

Answer

Nothing, it is supported

Question 10

Which action allows you to test a pattern against a specific Discovery status record without running a full Discovery scan?

Accepted Answer

Pattern Designer Test mode. The 'Test' feature in the Pattern Designer allows you to simulate execution against a specific Discovery node.

Answer

Modify Discovery Schedule

Answer

Submit a change request

Answer

Re-run Discovery

Question 11

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 12

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 13

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 14

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 15

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 16

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 17

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 18

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 19

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 20

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
