SERVICENOW-CIS-DISCOVERY Practice Test 4 — 25 Questions

Question 1

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 2

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 3

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 4

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 5

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

Question 6

You are modifying a pattern and need to extract a specific attribute from a JSON response returned by an API. Which step type is most appropriate for this task?

Accepted Answer

Parse JSON. The Parse JSON step type is specifically designed to parse structured JSON data and map values to variables.

Answer

Parse Variable

Answer

Set Parameter

Answer

Regex Extract

Question 7

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 8

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 9

What happens to the data extracted by a pattern if it is not mapped to an attribute?

Accepted Answer

It is discarded.. Data not mapped to an attribute is discarded after the pattern execution completes.

Answer

It is kept as a temporary CI.

Answer

It is stored in the error table.

Answer

It is saved in the discovery log.

Question 10

You have a PowerShell script step in your pattern that returns multiple key-value pairs separated by commas. What is the most efficient way to convert this output into a table format for further processing in the pattern?

Accepted Answer

Use the Parse Delimited Text step. The 'Delimited Text' parser allows you to specify a delimiter (comma) and map the results directly into a table structure usable by subsequent pattern steps.

Answer

Use a series of Set Variable steps

Answer

Use a Regex extraction step

Answer

Use the Table Transformation step

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

Which type of credential is primarily used by Discovery patterns to execute commands on a Linux-based target via SSH?

Accepted Answer

SSH Credentials. SSH Private Key or SSH Password credentials are the standard methods for Discovery to authenticate to Linux environments.

Answer

API Key

Answer

SNMP Community String

Answer

Windows Credentials

Question 13

What is the purpose of the 'mid.snmp.port' parameter?

Accepted Answer

To set the default port for SNMP discovery. This parameter defines the port the MID server listens on for SNMP traps or communicates via, depending on the discovery configuration.

Answer

To secure the connection

Answer

To set the heartbeat port

Answer

To configure the MID Server's web interface

Question 14

You are configuring a MID Server Cluster for high availability. What determines which MID Server in the cluster processes a specific task?

Accepted Answer

The 'Load Balancing' policy selected on the Cluster record. The Load Balancing policy determines how tasks are distributed among available MID Servers in a cluster.

Answer

The 'ECC Queue' record priority

Answer

The 'Performance Metric' score calculated by the instance

Answer

The 'Cluster Priority' field on the MID Server record

Question 15

Which THREE parameters are commonly found in the agent.config file?

Accepted Answer

mid.proxy.host. Proxy settings, instance URL, and thread counts are standard configurations within agent.config.

Answer

mid.db.connection

Answer

mid.user.password

Question 16

You need to upgrade a large number of MID Servers. Which feature should you use to avoid manual updates?

Accepted Answer

MID Server Auto-Upgrade. The MID Server Auto-Upgrade feature allows the instance to push updates to the agents automatically.

Answer

MID Server Update Sets

Answer

MID Server Cluster Overrides

Answer

Scheduled Jobs to restart services

Question 17

When a MID Server is 'Validated', what actually happens?

Accepted Answer

The instance trusts the MID Server's public key. The instance stores the public key from the MID server, establishing a secure trust relationship.

Answer

The MID Server is rebooted

Answer

The MID Server password is changed

Answer

The MID Server is updated

Question 18

A MID Server is failing to upgrade. What should you check first?

Accepted Answer

The upgrade log files on the MID Server host. The upgrade logs in the agent/logs directory provide insight into why an upgrade process failed (e.g., permissions, disk space).

Answer

The Discovery Schedule

Answer

The System Property list

Answer

The MID Server record status

Question 19

A MID Server is configured to scan a network segment but the scan fails with an 'Access Denied' error. Where should you look to ensure the MID Server is using the correct credentials?

Accepted Answer

Discovery Logs. The Discovery Logs provide the specific execution details, including which credentials were tried and rejected.

Answer

Service Mapping Logs

Answer

MID Server Logs

Answer

Credential Store

Question 20

What happens to the MID Server service if the host machine reboots?

Accepted Answer

It will start automatically if configured as a system service. The MID Server is typically configured as a system service, so it starts automatically upon OS boot.

Answer

It will stay down until manually started

Answer

It will be uninstalled

Answer

It will require a re-validation
