SERVICENOW-CIS-DISCOVERY Multiple Select — 30 Questions

Question 1

Which THREE actions should you take when troubleshooting a discovery process that is failing to populate the 'Serial Number' field for a specific class of routers?

Accepted Answer

Review the Identification Rule for the router class. Troubleshooting involves verifying the pattern execution, the identification rule logic, and the reconciliation rule settings.

Answer

Increase the Discovery timeout value

Answer

Modify the MID Server cluster configuration

Question 2

When configuring Data Sources for CMDB reconciliation, which TWO of the following are true regarding the behavior of the Identification and Reconciliation Engine (IRE)?

Accepted Answer

Data source importance determines which source takes precedence during a reconciliation conflict.. The IRE uses source priority and data source configuration to manage conflicting attribute data.

Answer

Custom data sources require a new Identification Rule for every CI class.

Answer

IRE ignores data sources that are not explicitly defined in the Identification Rules.

Answer

Discovery always has higher priority than manual CMDB updates by default.

Question 3

Which THREE of the following are components or features that are part of the 'Discovery' to 'CMDB' data pipeline?

Accepted Answer

Discovery Patterns. The pipeline includes data collection (Discovery), processing (IRE), and governance (Reconciliation).

Answer

Incident Management

Answer

Knowledge Management

Question 4

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 5

When the Identification and Reconciliation Engine (IRE) processes a payload, which THREE components determine if a CI is updated or created?

Accepted Answer

Data Source. The IRE relies on Identification Rules, Reconciliation Rules, and the payload content to make decisions.

Answer

MID Server configuration

Answer

Discovery Schedule

Question 6

Which TWO of the following are components of the Discovery process?

Accepted Answer

Shazzam. Shazzam and Exploration are key phases of the Discovery lifecycle.

Answer

Incident Management

Answer

Workflow Designer

Answer

Service Mapping

Question 7

Which THREE of the following are true about Discovery Behaviors?

Accepted Answer

They define which probes to use. Behaviors can be assigned to multiple schedules, can use custom probe lists, and default behaviors are available.

Answer

They automatically update the CMDB

Answer

They manage the MID Server cluster affinity

Question 8

Which TWO of the following are valid ways to define the scope of a Discovery scan?

Accepted Answer

IP Address ranges. Discovery ranges can be defined by specific IP address ranges or by using individual IP addresses.

Answer

Schedule Behaviors

Answer

MID Server Capability

Answer

Credential profiles

Question 9

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 10

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 11

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 12

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 13

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 14

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 15

Which THREE logs should you investigate when troubleshooting a failing discovery task?

Accepted Answer

Discovery log. Agent logs, wrapper logs, and discovery logs together provide a full picture of the execution path.

Answer

System log

Answer

Event log

Question 16

Which TWO actions should you perform to maintain the integrity of the CMDB when a CI is decommissioned?

Accepted Answer

Update the 'Operational status' field to 'Retired'.. To properly retire a CI, you must update its status and ensure it no longer appears in active discovery processes.

Answer

Delete the CI record from the database.

Answer

Clear the 'Last discovered' field.

Answer

Change the CI class to 'Archive'.

Question 17

Which THREE of the following items are considered 'CI Identification' best practices?

Accepted Answer

Keep identification rules as simple as possible to maximize performance.. Best practices for identification focus on stability, uniqueness, and minimizing rule sprawl.

Answer

Create a unique identification rule for every single CI instance.

Answer

Use the CI's 'Name' field as the primary unique identifier.

Question 18

Which THREE of the following are valid ways to improve the 'Correctness' metric in the CMDB Health Dashboard?

Accepted Answer

Refining identification rules to prevent duplicate CI creation.. Correctness is improved by reducing duplicates and ensuring that identification is reliable.

Answer

Running more frequent discovery scans.

Answer

Adding more fields to the CI classes.

Question 19

Which TWO of the following factors contribute to the CMDB Health Dashboard's 'Completeness' score?

Accepted Answer

Presence of required fields.. Completeness is measured by the presence of required and recommended fields on a CI record.

Answer

Number of duplicate CIs.

Answer

Number of relationships to other CIs.

Answer

Time since last discovery.

Question 20

Which THREE of the following are valid CMDB Health metrics?

Accepted Answer

Completeness. The CMDB Health Dashboard specifically tracks Completeness, Correctness, and Compliance (often interpreted as Relationships/Staleness).

Answer

Performance

Answer
